The Office of the Auditor General undertook a value for money audit of the operations of Regional Referral Hospitals (RRHs) to assess their efficiency in delivery of healthcare services at the regional level in Uganda. The overall objective of the audit was to assess whether there was efficient allocation and utilisation of resources in RRHs with specific focus on utilisation of medicines, health workers and infrastructure. The audit employed a benchmarking technique called the Data Envelopment Analysis (DEA) to determine the overall efficiency scores for each RRH over a period of three years. DEA compares different entities considering the resources used and services provided. The technique identifies the most efficient units or best practice units and the inefficient units in which real efficiency improvements are possible.

KEY FINDINGSBased on the results of this audit, the average inefficiency scores were 6%, 13% and 9% in the financial years (FY) 2011/12, 2012/13 and 2013/14, respectively. This implies that for instance in 2013/14, all the inefficient hospitals had the potential to reduce their inputs by 9% in total, while continuing to produce the same level of output. Approximately 50% of the RRHs exhibited this potential for improvement (input saving potential). Although there was an improvement in efficiency between 2012/13 and 2013/2014, there was still a considerable variation in the inefficiency levels of individual hospitals, ranging from 1% to 33%. The RRHs of Mbale, Moroto, Mubende, Masaka and Hoima were relatively efficient over the three years while Arua, Jinja, Kabale, Lira and Mbarara RRHs were relatively inefficient and hence had room for improvements over all the three years under review.

The sensitivity analysis conducted to ascertain the behaviour of the model, due to changes in the mix of the inputs and outputs, did not show much change in the score and rankings of the RRHs. This showed comprehensiveness of the input and output variables used and confirmed the credibility of the preferred model used in this audit.

As explained below, this audit has identified some of the potential areas that hospitals need to address in order to improve the efficiency with which they deliver their services.

1. Medicines and other health supplies• RRHs continued to have and accumulate expired drugs while also experiencing stock-

out of certain drugs over the 3 years under review. Expired items represent wastage of resources as they are purchased using funds that could be put to other areas of operation. They also take up space in the stores and more funds are required to ensure their safe destruction.

• A comparison was made of expenditures on medicines and health supplies with the standard unit of output to generate medicines utilized per unit of output1.It was observed that the value of medicines used per unit of output ranged between UGX 995 to UGX 2,417 (143% difference) in 2013/14, UGX 1,190 to 3,590 (200% difference)

1Ministry of Health Uganda generates a composite output measure called the Standard Unit of Output that converts all hospital outputs into outpatient equivalents. A unit of output is the equivalent of one outpatient treated (Refer to chapter 2 for the detailed definition)

in 2012/13 and UGX 1,031 to 3,177 (208% difference) in 2011/12. Whereas, there is no standard average amount of the value of drugs consumed by each patient, a hospital spending less for each patient will likely treat more patients using a given expenditure on drugs. Mbale RRH was the best performing hospital since it spent the least amount on drugs to treat one unit of output (the equivalent of one outpatient). Kabale, Soroti, Mbarara and Arua had the largest room for improvement compared to other RRHs in drug utilisation. The high variation in utilisation of drugs for each unit of output could be partly attributed to the extent of expiry of medicines and other health supplies at the affected hospitals and different preferences of treatment options by clinicians.

2. Infrastructure• Bed occupancy rates (BOR) over the 3 years ranged from 51% to 235%. Analysis

of data showed that that seven of the thirteen RRHs experienced floor admissions ranging from an average of 6 patients to 445 patients per day over the review period. Hospitals with BOR between 80% and 90% are considered to be operating optimally2. A bed occupancy rate below 80% implies that a hospital has many unutilized beds. For instance, it was noted that in Lira RRH, the 16-bed Intensive Care Unit (ICU) was unutilised while 7 out of 13 beds in the ICU of Jinja were not utilised. This partially contributed to their low average bed occupancy rates of 68% and 65% respectively.

Bed occupancy rates above 100% are caused by a huge influx of patients due to operational weaknesses in Health centre II, III and IVs. One such weakness is absenteeism of health workers in these health centres, prompting a large number of patients to seek health services from the referral hospital for conditions which a health centre should be capable of handling.

• It was observed that the number of hospitals that met the target Average Length of Stay (ALOS) of five days were increasing over the three year period. However, four (4) RRHs: Arua, Kabale, Moroto and Mubende showed no improvement in their ALOS over the three-year period, that is, their ALOS was increasing.

• It was noted that some of the infrastructure in RRHs was lying idle and/or under-utilized. This included beds, mattresses in Gulu and Lira and ICU equipment in Jinja and Lira. Money spent on the purchase of these items, estimated at $77,200 in total, could have been used for more pressing needs. In addition, such capital assets being left idle in stores could depreciate before the hospital derives the intended benefits.

• Analysis of data relating to X-ray and ultra sound machines utilisation (only functional machines for FY 2013/14) revealed that the RRHs exhibited big differences in the number of examinations conducted per machine for FY 2013/14. For X-ray machines, the annual number of examinations ranged between 887 in Arua to 8,782 in Masaka while number of ultra sound scans ranged between 629 images per scanner annually in Kabale to 6,309 in Gulu. It was also observed that a number of X-ray machines and ultra sound scanners were non-functional and this further limited the output of this vital equipment. That was an indication that availability of equipment is not commensurate to need.

3. Health workersRRHs lacked some specialized staff to deliver the services. At the time of the audit, most of RRHs visited had not achieved the required number of consultants, as per the established structure, to handle the specialized services.

KEY RECOMMENDATIONS1. Committees should be instituted in the inefficient RRHs to re-examine their

operational procedures with the view of identifying slacks in the utilisation of resources. This could be done by interacting with the efficient RRHs to ascertain the usage of inputs especially in the consistently efficient RRHs that is Mbale, Moroto, Mubende, Masaka and Hoima.

2. The Ministry of Health should ensure that budget allocations for drugs are commensurate to the output of hospitals so that stock-outs do not affect the provision of services in hospitals.

3. RRHs are advised to ensure that all clinicians adhere to treatment guidelines of the MOH while making prescriptions so that medicines supplied by NMS are well utilized. It is also recommended that a study on the stock-out levels of medicines be instituted in the RRHs to ascertain the impact on service delivery.

4. Stock taking exercises should be emphasized. This would enable the hospitals keep track of drug stocks, stock outs and thus provide a basis for planning.

5. The MoH should expedite the development of a system for redistribution of medicines and coordination between various players in the health system. RRHs should strengthen the tracking system of consumption patterns of medicines and other health supplies so that expected future orders do not materially differ from current plans.

6. The District Directors of Health Services at the districts should address the operational weaknesses in the Health centre II, III and IVs such as absenteeism, lack of medicines which results in the RRHs being overstretched.

7. Shortage of health workers should be addressed by putting in place mechanisms that would attract and retain these professionals to the RRHs.

8. RRHs with unutilised and underutilised equipment should consider redistributing them to other health units that would put these items to better use.

9. The MOH is advised to develop staffing structures suitable for the needs of RRHs.

OVERALL CONCLUSIONThe results of the efficiency study of the operations of RRHs using the data envelopment analysis technique have shown that 50% of the RRHs were relatively efficient in the utilization of their resources. The remaining inefficient hospitals exhibited potential for improvements if appropriate interventions were made to address the slacks in the utilization of the key inputs such as medicines, infrastructure, /equipment and human resource.

With reduced inefficiency, RRHs stand to reap significant input savings from their activities. This would ensure improvements in the coverage and quality of health services.

CHAPTER ONE

INTRODUCTION

1.1 BACK GROUNDIn Africa, particularly sub-Saharan Africa, poor health of the population is generally a known reality and Uganda is no exception to this. The healthcare delivery systems remain too inadequate to meet the needs of the ever-growing population. This has raised concerns by policy makers and planners on whether health services are being delivered efficiently by hospitals.

In Uganda, hospital services are provided under a four-tier health care system, that is, primary, secondary, tertiary and quaternary with Regional Referral Hospitals being major contributors to essential clinical care because of their provision of specialist clinical services.

This audit covered thirteen out of the fourteen Regional Referral Hospitals in Uganda, namely: Arua, Fort Portal, Gulu, Hoima, Jinja, Kabale, Lira, Masaka, Mbale, Mbarara, Moroto, Mubende and Soroti.

1.2 MOTIVATIONA number of international treaties3 oblige the Government of Uganda to commit sufficient resources and establish a comprehensive healthcare framework that meets the health needs of the citizens. Besides, the State has a duty to guarantee the right to health to all its citizens.

In order to deliver the required health services, the Government of Uganda (GoU) endeavoured to put in place a regulatory framework4 in line with the 1995 Constitution of the Republic of Uganda (as amended). The regulatory framework spells out the services of hospitals at different levels including Regional Referral Hospitals (RRHs), in providing the healthcare needs of the population.

Over the past three financial years 2011/12, 2012/13 and 2013/14, there has been an 18% increment in the funding of RRHs from UGX 53.86 billion to UGX 63.56 billion.5

Despite the increment in funding of RRHs, over the years, there are investigative and research reports,6 as well as press reports, about the declining quality of health services in the country, mainly attributed to the lack of drugs/ stock outs, shortage of health workers, delays in accessing healthcare services in every referral hospital, mismanagement of hospital infrastructure, overcrowding of hospital facilities, among others; with dire

consequences, including avoidable deaths of patients. This has raised concerns as to whether these hospitals are operating efficiently with the resources availed to them.

There is need for efficient provision of clinical and non-clinical services to attain a healthy population as an input for economic development.

The inefficiency in RRHs is an issue that needs to be addressed if Uganda is to reap significant savings from all activities carried out by RRHs and meet its Millennium Development Goals (MDGs) related to health.

It is against this background that the Office of the Auditor General decided to undertake an independent assessment of the operations of the RRHs to ascertain their efficiency in delivery of health care services at the regional level in Uganda.

1.3 DESCRIPTION OF THE AUDIT AREA

1.3.1 General DescriptionUganda has 14 self-accounting RRHs which are responsible for delivering a complementary, integrated, and continuous package of health care to achieve a common national goal. RRHs offer specialised services such as Psychiatry, Ear, Nose and Throat (ENT), Radiology, Pathology, Ophthalmology, higher level surgical and medical services, including teaching and research. This is in addition to the services offered at general hospitals. RRHs are required to provide care for a population of 2,000,000 people, have a bed capacity of 500, employ an average of 349 members of staff and maintain all the relevant health equipment as prescribed by the Ministry of Health (MoH).

1.3.2 Legal Framework for RRHsThe Uganda Hospital Policy provides for RRHs as part of the health service delivery system of Uganda. The policy states that RRHs offer all services of general hospitals in addition to specialized services such as psychiatry, Ear, Nose and Throat (ENT), radiology, pathology, ophthalmology, higher level surgical and medical services, including teaching and research.

1.3.3 Mission and VisionRRHs derive their visions and missions from that of the Health sector which is:

Vision “A healthy and productive population that contributes to social-economic growth and national development”

Mission “To provide the highest possible level of health services to all people in Uganda through delivery of promotive, preventive, curative, palliative and rehabilitative health services at all levels.”

1.3.4 Organizational StructureRRHs have the Management Board as the highest authority which provides oversight on the activities of the hospital. The executive function is headed by the Hospital Director. (For details, refer to Appendix II)

1.4 AUDIT OBjECTIVESThe overall objective of the audit was to assess whether there is efficient allocation and utilisation of resources in RRHs.

The specific objectives of the audit were:

a) To determine the overall efficiency score of each RRH with respect to the provision of health services.

b) To assess and compare the efficiency in utilisation of key inputs, that is, health infrastructure (beds and equipment), health workforce and medicines and other health supplies in RRHs.

1.5 AUDIT QUESTIONSa) What are the overall efficiency scores for each RRH with respect to provision of health

services?

The standards require that the audit is planned in a manner which ensures that an audit of high quality is carried out in an economic, efficient and effective way and in a timely manner.

2.1.1 SamplingOut of the fourteen (14) hospitals, a sample of thirteen (13) were selected, that is, Fort Portal, Gulu, Jinja, Lira, Masaka, Mbale, Mbarara, Mubende, Moroto, Arua, Kabale, Hoima and Soroti. Naguru Regional referral hospital was excluded because it was not fully functional during FY 2011/12, one of the financial years under review.

2.1.2 Data Collection MethodsThe data collection methods used to obtain audit evidence for the audit were:

• Document review: The team reviewed policy guidelines from the Ministry of Health and annual health sector performance reports to obtain an insight into the operations of hospitals. Previous studies on hospital efficiency were also reviewed to ascertain similar characteristics that were incorporated in the report.

• Interviews: Interviews were conducted with officials of MOH, management and staff of RRHs and management of National Medical Stores (NMS) to seek clarification on the issues identified through data analysis.

• Physical inspections: Nine (9) RRHs were selected for inspection. The inspection was conducted to validate data and other information obtained from MOH and from document review.

• Questionnaires: These were sent to 4 RRHs which were not covered through physical inspection, namely: Arua, Kabale, Moroto and Hoima. However, only Kabale RRH responded to the questionnaire.

• Reference group discussion: A workshop was held with the responsible officials from the Ministry of Health, Directors of RRHs and Hospital administrators, in which findings were presented and discussed. Subsequently, their input was incorporated in the final audit report.

Data was collected from the Health Management Information System (DHIS-2) and corroborated with that from the 13 RRHs under review. Data on medicines and health supplies was further corroborated with that from (NMS) data records.

2.1.3 Data Envelopment AnalysisData Envelopment Analysis (DEA) was used to assess the efficiency of each RRH. This was achieved by comparing the mix of inputs and outputs of each unit with those of all the other units.7 In this audit, the service units were the RRHs across the financial years 2011/2012, 2012/2013 and 2013/2014.

2.1.4 Data AnalysisFurther data analysis was carried out to explain the results of DEA. This involved ratio analysis, interpretation of performance indicators commonly used in health services, correlations and graphical comparisons. This analysis was used to provide explanations for the efficiency performance.

2.2 THEORETICAL FRAMEWORK OF DEADEA is a benchmarking technique which compares different entities called Decision Making Units (DMUs) considering resources used and services provided. A DMU could either be a firm or an organization, as in this case.8 In DEA analysis, efficiency refers to the success of the DMU in producing as large as possible output from a given set of inputs (output based) or using the least amount of resources to meet a target in production (input based). The technique identifies the most efficient units or best practice units and the inefficient units in which real efficiency improvements are possible. In the context of health, the DMU is the referral hospital and the technical efficiency can be described as producing a given level of health service outputs with the least health system inputs.

Efficiency can be assessed using a number of analysis tools such as ratio analysis, regression analysis, unit cost measurement, Stochastic Frontier analysis. Most studies on efficiency of hospitals have used Data Envelopment Analysis. This is mainly due to the fact that hospitals have an array of inputs and outputs that would render most methodologies ineffective.

The DEA model is a model that makes it possible to determine the presence and amount of inefficiency within each RRH. This information can thus be used by management to aid policy decision-making and resource allocation. (Further illustration of DEA is in Appendix III)

2.2.1 Previous StudiesDEA has been widely used to measure the efficiency of hospitals and a number of efficiency studies from different countries have been published. A review of these previous studies on hospitals revealed common traits which have been summarized in Appendix IV.

Most of these studies considered “beds” and “human resource” as inputs and, “outpatient services” and “inpatient services” as outputs. The most common indicator used to capture the quality of health service was mortality rate. Most studies assumed both the Variable Returns to Scale (VRS) and Constant returns to Scale (CRS).

7Sherman, H.D.; Zhu, J.; 2006; Service Productivity Management: Improving Service Performance using Data Envelopment Analysis, p508The DEA framework was introduced by Farrell(1957) and extended to situations with multiple inputs and outputs by Charnes, Cooper and Rhodes (1978), Measuring the efficiency of decision making units, CCR 1978 (page 429)

2.2.2 The Data SetThe dataset includes thirteen (13) RRHs for the three (3) financial years 2011/2012, 2012/2013 and 2013/2014. It was sourced from the Health Management Information System (DHIS-2) under the management of the Ministry of Health. HMIS data was used because it is the recommended data source for the health sector due to its reliability. The audit also obtained data from the RRHs.

For each hospital, the dataset included number of health workers, beds, diagnostic equipment, diagnostic tests, outpatient attendance, admissions, deliveries, hospital deaths, still births, live births, immunization data, ANC visits, standard unit of output, drug expenditure and other operating costs. These were discussed with the RRH directors to agree on what they considered key inputs and outputs of the RRH.

2.2.3 Model SpecificationThe input and output variables were chosen based on discussions with the RRHs, the hospital production process and on the commonly used variables in previous similar research studies on efficiency of hospitals as explained above.

Input VariablesThe input variables used in our preferred model included:

a) Health workers: These were chosen because they are directly involved in the provision of health services to patients. Furthermore, the wage bill of RRHs constitutes about two thirds of their total operating cost. Health worker category included medical professionals (medical officers, specialists and consultants), nursing staff, midwifery staff, dental professionals, allied health professionals.

b) Beds: This is commonly chosen in hospital studies as a proxy for capital investment and hospital size9.

c) Drug expenditure: This represents the treatment given to both the inpatients and outpatients. It constitutes the actual expenditure on essential medicines and health supplies.

Output Variablesa) Standard unit of Output (SUO): This is a composite output measure converting

all outputs of the RRH into outpatient equivalents. SUO total = [(Inpatients x15)+ (Outpatients x1) + (Deliveries x5) + (Immunizations x0.2) + (ANC/MCH/FP1 x0.5)]10. It is based on earlier work of cost comparisons and is used by the MoH in the Annual Health Sector Performance reports to make a uniform and fair comparison of outputs across hospitals that have varying capacities.

Furthermore, SUO captures the different types of patient care services provided by the RRHs such as outpatient services, inpatient services, maternity services, and prevention and rehabilitation services.

b) Hospital deaths: This variable was used as a rough measure of the quality of health care provided by the RRHs. It is assumed that the more deaths a hospital encounters, the lower the quality of its services. This same parameter was used in previous studies as a quality measure as discussed earlier.

Source: OAG Analysis of data from RRHs

The mean and standard deviation serve to show that the quantity of each input and output generally varies amongst the RRHs and from one year to another. The only exceptions are health workers and beds which remain fairly constant on a year-on-year basis. The aforementioned variation necessitated that the efficiency analysis be carried out separately for each year in order to obtain unbiased results.

2.2.4 Sensitivity AnalysisA sensitivity analysis was carried out using four models in order to assess the credibility of the results and the comprehensiveness of the variables. The input and output variables used for each model were:

SYSTEMS AND PROCESS DESCRIPTION

3.1 PROCESS DESCRIPTION

3.1.1 BudgetingThe User department/unit of the RRH generates priorities and the Head of Department or unit presents them to Top Management which serves as a Budget Committee. The Top management develops work plans and budgets which are presented to the Hospital Management Board, which is the link to the community served by the respective referral. The budget is presented to the Ministry of Health for consideration. However, sometimes the Ministry has its own priorities as per government policies. Feedback is then given to the respective players by the top management.

Budgeting for medicines and other health suppliesIndicative planning figures (IPFs) are set and presented to RRHs as ceilings for expenditures on medicines and other health supplies. Procurement plans are developed based on these ceilings and sent to NMS which has the mandate to procure and distribute medicines and other health supplies to all government health units in the country. NMS then develops its own procurement plan for drugs by amalgamating procurement plans for all the government health units. Funds for these items are sent directly to NMS for general procurement and deliveries made to health units based on a predetermined schedule.

3.1.2 Outpatient serviceWhen patients arrive at the Outpatients Department (OPD), their personal details are registered by the records officer. They are directed to the clinician or the dentist. The patient’s complaint is then considered and the patient is sent to the laboratory where the lab attendant carries out the required tests and sends the patient, with the results, back to the clinician. Based on the results, the clinician makes a diagnosis and gives the patient a prescription or recommends them for admission. The clinician may send a patient to a consultant or one of the specialized clinics such as Tuberculosis, Diabetes, if they need a specialized service. The patient receives the prescribed drugs from the pharmacy.

3.1.3 Inpatient serviceWards receive patients from the Outpatients Department, referrals from other hospitals and patients from their homes. All patients are received by the ward in-charge or any medical staff on duty, depending on the different shifts. Each patient has a personal file which is referred to on admission and where necessary, tests are done. Different wards have different procedures for treating their patients, for example: in the surgical ward, a Complete Blood Count (CBC) and X-ray is done prior to operation. In the maternity ward, mothers are examined: those in latent labour admitted in the maternity ward, and those in established labour admitted in the labour suite. Expectant mothers with other complications, such as: pregnancy-induced hypertension, malaria are also admitted and monitored. Referrals and other complications are handled by the specialized doctors.

FINDINGS AND RECOMMENDATIONSThis chapter presents the efficiency-score results of the preferred model and the sensitivity analysis carried out. Conclusions, recommendations and other issues affecting performance of RRHs are also detailed thereafter.

4.1 RESULTS

4.1.1 Efficiency Scores of RRHsTable 3 presents the calculated annual efficiency scores for the different RRHs during the chosen period. The score required to be a benchmark hospital is 100%. Any score below 100% suggests an input saving potential given the level of outputs produced by the RRH in that particular year.

M A R C H 2 0 1 5 19THE EFFICIENCY

OF OPERATIONS OF REGIONALREFERRAL HOSPITALS IN UGANDA

For example, the efficiency score for Mbarara RRH of 83% in 2012 implies that it is possible to reduce its inputs by 17% and maintain its current level of outputs. By doing so, Mbarara RRH will become 100% efficient. For further illustration, consider the total recurrent expenditure of Mbarara RRH in 2012/2013 of UGX 4,528,189,274. This RRH has the potential to reduce its annual recurrent expenditure by UGX 769,792,176.58 while delivering the same level of output in terms of SUO. Details of the saving potential per RRH on recurrent expenditure for FY 2012/13 are shown in Appendix V.

From Table 4 above, the average inefficiency score varied between 6% and 13% over the three-year period and approximately 50% of the RRHs were inefficient. Although there was an improvement in the average inefficiency score between 2012/13 and 2013/2014, there was still a considerable variation in inefficiency scores among the RRHs from 1% to 33%.

The sensitivity analysis conducted to ascertain the behaviour of the model due to changes in the mix of the inputs and outputs did not show much change in the score and rankings of the RRHs as shown in Appendix VI. This further emphasizes the comprehensiveness of the input and output variables used and the credibility of the preferred model.

Management ResponseThe efficiency results from the DEA model should be interpreted with caution and in the context of the health care system as higher level health facilities such as regional referral hospitals can appear inefficient, for example, because of relatively longer stays due to patient mix, staff skill mix and staff cost associated with specialists. However, this may be an indication of the effectiveness of the health system in referring individuals with serious health conditions to better equipped health facilities.

Audit Comment Regional referral hospitals in Uganda are required to offer the same services as detailed in section 1.3.1 of this report (description of the audit area). They also employ the same categories of human resource who are paid based on the Government of Uganda salary structure at their various levels of specialisation.

The tool used to compute efficiency scores in this study assessed the use of inputs of a hospital relative to usage of the same inputs by counterpart hospitals.

The results are therefore reliable and showed a potential for improving efficiency in the RRHs by saving on the inputs currently used to produce outputs. At the individual hospital level, this saving potential ranged from 1% to 33. It implies that these RRHs have gaps that hindered the provision of the highest possible level of service. The saving potential of each RRH varies and may not be uniform across all inputs.

RecommendationCommittees should be instituted in the inefficient RRHs to re-examine their operational procedures with the view of identifying slacks in the utilisation of resources. This could be done by interacting with the efficient RRHs to ascertain the usage of inputs especially in the consistently efficient RRHs that is Mbale, Moroto, Mubende, Masaka and Hoima. Based on interviews, reviews of documentation and data analysis undertaken in the course of this study, the potential areas of interest could include but not limited to those identified in section 4.2 below.

4.2 UTILISATION OF KEY INPUTSIn measuring the efficiency of RRHs, the audit analysed the use of key inputs, that is, medicines and other health supplies, health infrastructure and health workforce in the delivery of health services and how they impact on the efficiency of operations of RRHs. The following was observed:

4.2.1 Analysis of Medicines Management and Utilisation

a) Variances in Medicines Utilisation

RRHs committed to attaining value for money in the delivery of their outputs in the Ministerial Policy Statements by ensuring efficiency in utilisation of resources. Medicines and health supplies are an essential input in all RRHs. Analysis of the relationship between unit cost of drugs and the efficiency scores, showed that efficient hospitals had lower expenditures on medicine per unit of output. (Appendix VII (b)).

A comparison was made of the expenditures on medicines and health supplies with the standard unit of output to generate medicines utilized per unit of output as shown in Table 5 below. It was observed that the value of medicines used per unit of output ranged between UGX 995 to 2,417 (143% difference) in 2013/14; UGX1,190 to 3,590 (200% difference) in 2012/13; and UGX1,031 to 3,177 (208% difference) in 2011/12. Whereas, there is no standard average amount of the value of drugs consumed by each patient, a hospital spending less for each patient will be likely to treat more patients using a given expenditure on drugs. In this case, Mbale RRH was the best performing hospital since it spent the least amount on drugs to treat the equivalent of one outpatient. Kabale, Soroti, Mbarara and Arua performed lowest compared to other RRHs in drug utilisation. This affected their efficiency score as was illustrated in Table 4.

OF OPERATIONS OF REGIONALREFERRAL HOSPITALS IN UGANDA

The high variation in utilisation of drugs for each unit of output was partly attributed to the extent of expiry of medicines and other health supplies at the affected hospitals and clinician preferences for expensive drugs over cheaper alternatives.

The difference expressed by the figures above is an indication of wide variations in the pattern of drug prescription and consumption across the RRHs and may, in part, account for differences in overall hospital efficiency. It also indicates the potential for savings in drugs expenditure after critical assessment of the economic consequences of how drugs are managed in hospitals.

Management responseThe variations could result from differences in levels of stock-outs of medicines across the RRHs in the country. Hospitals that see more patients compared to the available medicines and thus have to give prescriptions for the patients to source for the medicine outside the hospital may seem more efficient. Differences were also attributed to varying prescription patterns by specialists.

Audit Comment It is true that variations in medicines could result from differences in stock-out levels across the RRHs. That being the case, hospitals spending less on medicines for every unit of output would have a bigger need for medicines than those spending more. This implied that the budget for medicines was not allocated according to the outputs of the hospitals.

Recommendation•The Ministry of Health is advised to ensure that the budget allocated to hospitals

is based on the output of hospitals so that stock-outs do not affect the provision of services in hospitals.

•RRHs are advised to ensure that all clinicians adhere to treatment guidelines of the MOH while making prescriptions so that medicines supplied by NMS are well utilized. It is also recommended that a study on the stock-out levels of medicines be instituted in the RRHs to ascertain the impact on service delivery.

b) Expired and shortage of drugs

According to the Ministry of Health Ministerial Policy Statement, National Medical Stores (NMS) is supposed to procure and distribute essential medicines and health supplies in accordance with procurement plans for RRHs.

According to the RRH delivery schedule, NMS is supposed to deliver essential medicines after every two months which translate into six cycles in a year. The orders and delivery should be in line with the RRH procurement plan to curb the expiry and shortage of drugs in RRHs and ensure effective service delivery.

Inspections, interview and review of the stock cards made in 9 RRHs13 revealed that RRHs continued to have and accumulate expired and experience stock out of medicines over the 3 years under review.

Hospital managers attributed the expiry to changes in morbidity patterns, changes in treatment policies, delivery of drugs with a short shelf-life and the push system of supplies

13This is respect to all 9 RRHs visited by the audit team. There was no information provided by the 4 unvisited hospitals.

delivery where NMS supplied items not ordered by the hospital while the shortage was due to NMS failure to deliver what is actually required. Analysis of drug deliveries indicated that NMS supplied more items towards the end of the year than at the beginning contrary to the procurement plan.

Whereas, expiry and shortage of drugs was partly attributed to the irregular deliveries of health supplies by NMS, in an interview with the NMS General Manager, it was noted that the expiry and shortage of the drugs in RRHs was also due to improper planning by the RRHs in their annual procurement plans. Whereas, hospitals are allowed a variance between order and plan of 20%, it was observed that all RRHs exceeded this allowance at time of ordering. This contributed to the stock outs of drugs.

In Mubende, it was noted that the RRH had eight stores dispersed across the hospital premises yet it only had one stores assistant in charge of all these stores. Furthermore, the stores assistant seldom conducted stock-taking exercises to confirm that balances of inventories on record physically existed. Without a proper procedure of taking inventory of the stores, the stores assistant could not identify and report any expired medicines and those medicines nearing expiry so that management could devise strategies to counter losses before expiry such as redistribution/donation of the medicines to other health units.

It was also observed that in the RRHs where physical counts were conducted, no reports were made to the accounting officer. As a result, the RRHs did not have the actual balances of medicines in their stores which further led to requisitioning for less or more than what was needed.

In Jinja, Mubende and Gulu, it was also observed that expired drugs were mixed with unexpired drugs. Whereas, this was attributed to lack of storage space, the team noted that this practice increased the probability of issuing expired drugs to users.

Management Comment

The MoH redistribution strategy and the improvement in the hospital quantification capacity, computerization of stores and the continued use of the pull system of EMHS from NMS would progressively reduce both levels of expired medicines and stock-outs as coordination in the health systems improved.

Audit Comment Expired items represented wastage of resources as they were purchased using funds that could be put to other areas of operation. They also take up space in the stores and more funds are required to ensure their safe destruction.

Recommendations• Stock taking exercises should be emphasized. This would enable the hospitals

keep track of near expiries, stock outs and thus be a basis for planning.

• The MoH should expedite the development of a system for redistribution of medicines and coordination between various players in the health system. RRHs should strengthen the tracking system of consumption patterns of medicines and other health supplies so that expected future orders do not materially differ from current plans.

• The hospitals should prioritize the construction of consolidated stores to ease the distribution of drugs to different units and stock taking.

4.2.2 Infrastructure Usage

a) Beds

According to the Annual Health Sector Performance Reports of 2012/13 and 2013/14, bed utilisation is assessed using indicators such as bed occupancy rate and average length of stay.

i) Bed occupancy rate

The bed occupancy rate is an indicator of the average proportion of beds in the hospital which are occupied by patients in a day. A bed occupancy rate of 100% would imply that all the hospital beds were occupied by patients on a daily basis. Hospitals with BOR between 80% and 90% are considered to be operating optimally.14 Through interviews with the Directors of RRHs, it was established that this provides an allowance for emergency admissions. Coupled with a moderate length of stay, an optimal BOR would ensure the readiness of the hospital to take in more admissions. The bed occupancy rate varied among the RRHs as shown in the Table 6 below.

From Table 6 above, bed occupancy rates over the 3 years ranged from 51% to 235%.

A bed occupancy rate of below 80% implies that a hospital has many unutilized beds. For instance; it was noted that in Lira and Jinja, there were 16 beds and 13 beds respectively in their Intensive Care Units that were underutilized. This partially contributed to their low bed occupancy rates. Inspection of the store in Gulu RRH revealed 20 unutilised beds.

High bed occupancy rates (that is above 100%) were caused by a huge influx of patients due to operational weaknesses in Health Centre IIs, IIIs and IVs. One such weakness was absenteeism of health workers, prompting a large number of patients to seek health services from the referral hospital for conditions which these lower health centres would have been capable of handling. For example, an interview with a midwife at Mbale RRH revealed that expectant mothers travel long distances from the neighbouring districts seeking the services of a midwife because of lack of midwives at the Health Centre IIIs or IVs.

Furthermore, from document review15, absenteeism rates of health centres IIs to IVs in the financial year 2011/12 also contributed to the high bed occupancy rates in RRH. Table 7 below shows the absenteeism rates of health workers at the various health centres during 2011/12.

Health Centre II 25%

Health Centre III 30%

Health Centre IV 50%

Source: Annual Health Sector Performance Report, 2012-2013, p35

Audit CommentThe RRHs with a bed occupancy rate above 100% may have a low preparedness for emergency admissions. In addition, it diminished the quality of health services provided by the hospital arising from floor admissions. Through a review and analysis of patient days and available beds over the three years under review, we noted that six of the thirteen RRHs experienced floor admissions ranging from an average of 6 to 445 patients per day over the review period as shown in Table 6. Discussions with Hospital Directors revealed that the floor admissions increase the risk of patient to patient infections therefore prolonging their recovery and stay at the hospital.

ii) Average Length of Stay

Analysis of Data shows that the average length of stay of patients affects the performance of RRHs in delivering inpatient services. RRHs with a higher average length of stay tend to have fewer admissions yet the number of available beds remains unchanged (Figure 2 below refers). For example, the hospitals which had ALOS of 3 days reported admissions over 40,000 on average, while an average of only 10,000 admissions were reported where the ALOS was 8 days. This is because if inpatients are admitted for long periods, fewer beds will be available to accommodate new ones.

From Table 6 above, audit noted that four (4) RRHs such as Arua, Kabale, Moroto and Mubende showed no improvement in their ALOS over the three-year period i.e. their ALOS was increasing.

It was noted that one of the causes of a high average length of stay in RRHs is the shortage of medical specialists. From interviews with the Hospital management16, it was noted that where there were fewer medical specialists such as medical officers- special grade, consultants, and senior consultants, the average length of stay tends to be high because patients suffering acute illnesses spend extra days admitted in the hospital, waiting in line to receive treatment from the few available specialists.

This was confirmed by a comparison of the number of medical professionals in a RRH and its average length of stay (Figure 3 below refers). The average number of medical specialists across the RRHs is 8. Moroto and Kabale which reported average length of stay above 5 days had fewer medical specialists than the average of 8. Masaka, Mbarara, Soroti and Jinja which had an average length of stay below 5 days were found to have more medical professionals than the average of 8.

b) Idle Infrastructure

Infrastructure is considered a key focus and a priority intervention in health system strengthening.17 In addition, the National Committee on Medical Equipment (NACME) Standard Equipment list 2009 prepared by the Ministry of Health sets out the type and quantity of equipment required by a RRH.18

Efficiency is achieved when the available resource inputs are applied in a way that maximises the desired output. Although health infrastructure is a key input of RRHs, it was noted that some of the infrastructure in RRHs was lying idle and/or under-utilised.

i) ICU Facilities in jinja and Lira RRHsFor example, inspections and interviews in Jinja and Lira RRHs revealed that Jinja RRH which ran a 13-bed Intensive Care unit only used 6 of the beds, leaving 7 beds idle in the unit while Lira RRH had not utilized its 16-bed ICU since FY 2012/13. The Hospital Directors of Jinja and Lira RRHs explained that more nurses would have to be deployed as each bed required at least 2 full time nurses to the unit to ensure full utilisation of the unit without compromising the quality of care. The unit would also require full time doctors and an anaesthesiologist. In Lira RRH, management explained that the ICU had not been commissioned and that its underutilisation was also due to the absence of an oxygen plant. However, audit noted that the ICU facility was completed in the FY 2012/13 and that Jinja RRH, which had no oxygen plant, had partially utilized its ICU. It was also observed that the oxygen plant had not been planned for.

With the current ICU bed capacity in Uganda of 61 in all public and private hospitals, 23 unutilized ICU beds in Jinja and Lira represents a wasted resource. It is estimated that about 10 critically ill patients were deprived of ICU admission daily and as a result succumbed to their illnesses19.

ii) Idle beds in Gulu RRH Inspection of the main store at Gulu RRH revealed that 20 mattresses, 20 pillows and 20 beds had been kept in the stores for more than one year as shown in Picture 1 below. The stock cards indicated that these items had been acquired by the hospital in 2013 but had never been handed over to any ward for usage.

Gulu RRH management explained that the mattresses were a donation at a time when the hospital had enough mattresses and all the beds commonly used had mattresses. The store keeper further explained that the mattresses could not be distributed without protective plastic mattress covers as they would easily be soiled by patients. The audit team however, attributed this to poor planning as these covers were not planned for in the financial years 2012/13 and 2013/14.

It was also noted that in 2011/12, the bed occupancy rate of Gulu RRH was below 100% and there were no floor admissions. This goes to show that no proper needs assessment was carried out before procuring these items.

Lira faced a similar challenge with 15 beds stacked up in their store for over a year.

iii) Imaging Equipment in Mbale RRH In Mbale RRH, imaging equipment donated by the Japan government had been idle for part of the FY 2013/2014. Interview with the principal hospital administrator revealed that

the equipment was not repaired promptly because the spare parts and technical repair skills were not available on the Ugandan market.

iv) Idle Equipment in Mubende RRH In Mubende RRH, inspection of the stores established that two slit lamps, four oxygen therapy apparatus machines and one operating cold light unit which was supplied by Uganda Health Systems Strengthening Project (UHSSP) have been idle for 1 year (since 2013).

Management responseSome of the equipment was acquired through donations and not procured by the RRHs. The donated mattresses in Gulu were received at a time when the hospital had an adequate stock of mattresses and kept them as buffer stock. All the commonly used beds have mattresses. Consideration was not made for additional requirements of the ICU in Jinja namely: presence of an anaesthesiologist, specialised nurses and doctors, a darkroom and maintenance funds.

Audit Comment Any unutilised equipment (whether donated or procured by the RRH) represents an idle resource. The money spent on the purchase of these items, estimated at United States dollars (US$77,200 in total (as shown in table 9 below) could have been put to procurement of more pressing equipment in the hospital such as diagnostic equipment. In addition, such capital assets being left idle in stores could depreciate before the hospital derives the intended benefits.

c) Utilisation of X-ray and Ultrasound Machines

RRHs are committed to attaining value for money in the delivery of their outputs by ensuring efficient utilisation of resources. Carrying out diagnostic testing and examinations for both outpatients and inpatient services is a key output of RRHs as spelled out in the Ministerial Policy Statements for MoH.

Analysis of data relating to utilisation of X-ray and ultra sound machines (only functional machines for FY 2013/14) revealed that the RRHs exhibited big differences in the number of examinations conducted per machine per year. For X-ray machines, the number ranged between 887 in Arua to 8,782 in Masaka (as shown in Table 10 below) while usage of ultra sound scans ranged between 629 images per scanner per year in Kabale to 6,309 in Gulu as detailed in Table 11 below.

It was also observed that a number of X-ray machines and ultra sound scanners were non-functional and this further limited the output of these vital equipment.

The low performance of hospital equipment was mainly due to lack of routine and proper maintenance. Hospital managers in response attributed this to the lack of bio medical engineers and high costs of repairing the equipment, for instance, according to Jinja RRH, the maintenance of the En-Visor ultra sound machine and the repairs of the Duo-Diagnostic big x-ray machine requires not less than UGX 15 million, and without a medical equipment maintenance fund, it is a challenge to maintain and repair the radiology and imaging machines.

Management of Fort Portal RRH attributed the low usage of the x-ray and ultrasound machines to stock-outs of the supplies, such as reagents and films required for the operation of this diagnostic equipment.

Management responseOne of the machines in Fort Portal was a mobile x-ray for limb fractures and its outputs were not expected to be the same as the main digital x-ray. Similarly the second ultrasound machine was acquired toward end of 2013/14. The demand for services was high but x-ray and ultrasound has been one of the areas where supplies have not been consistently delivered.

Audit Comment Whereas, mobile x-ray machines were expected to conduct less x-ray examination, as was the case in Fort Portal, the analysis as shown in the Table 9 above indicated that availability of additional machines was not commensurate to need. For example, Masaka and Hoima which had the highest numbers of x-ray examinations conducted had only one x-ray machine while Soroti and Hoima with much lower numbers of examinations had 2 machines each.

Recommendations• The District Directors of Health Services at the districts should address the

operational weaknesses in the Health centre II, III and IVs such as absenteeism, lack of medicines among others, which results in the RRHs being overstretched.

• Shortage of health workers should be addressed by putting in place mechanisms that would attract and retain these professionals to the RRHs.

• RRHs with unutilised and underutilised equipment should consider redistributing them to other health units that would put these items to better use.

• Lira RRH is advised to expedite the commissioning of the ICU and benchmark from Jinja RRH on the alternative sources of oxygen in the absence of an oxygen plant.

4.2.3 StaffingRRHs are mandated to provide specialized services such as Obstetrics and Gynaecology, Surgery, Paediatrics, Medicine, Psychiatry, Ear Nose and Throat (ENT), Ophthalmology, dentistry, intensive care, radiology, pathology, higher level surgical and medical services training and research in addition to general health care services20. In order to meet this mandate, they are required, in coordination with Health Service Commission, to recruit highly specialized personnel in the various areas. Furthermore, WHO recommended a patient: doctor ratio is 800:1.21

However through interviews with the hospital directors and administrators and analysis of the approved staffing structures, it was noted that all RRHs have not recruited all the specialized staff to deliver the services. At the time of the audit, most of RRHs visited had not achieved required number of consultants as per the established structure to handle the specialized services of the RRHs as shown in table 11 below.

Source: RRHs staffing structures.

Moroto had the worst case scenario with no consultant, followed by Gulu with only one consultant who was doubling as the Hospital Director, followed by Lira and Mubende.

RRHs are staffed according to staffing norms approved by the Health Service Commission. The staffing levels in some areas do not enable RRHs to fulfil their mandate of providing specialized service. The staffing situation in the hospitals is inadequate and there is wide variance across all RRHs.

Through document review of the annual health sector performance report 2012/13, it was revealed that the ratio of patients to clinicians was high in RRHs and varied from one RRH to another. The average doctor-patient ratio per year in RRHs was 12440:1 implying one doctor for 34 patients per day while clinician- patient ratio was 10652:1 annually implying one clinician for 29 patients.

In an interview with the management of each RRH, the situation was attributed to failure by the hospital to retain health workers due lack of accommodation, and remoteness of some referral hospitals.

Interviews with ministry officials confirmed the assertion that geographical location of some referral hospitals affected their ability to attract health workers.

As a result, there was distributive inefficiency leading to some referral hospitals having to refer patients to other referral hospital for specialized services. For example; Kabale, Fort Portal, Masaka and Mbale Regional Hospitals referred some special cases to Mbarara RRH for services like CT scan, renal dialysis, neurosurgeon, paediatric surgery. In addition, lack of adequate staff has led to referrals to the National Referral Hospital and this has further resulted in the congestion and handling of cases at National Referral Hospital which cases could be handled by the RRHs. The process of referrals is costly and in some cases patients lose their lives in the process of reaching the health facility to which they have been referred.

Management responseStaffing needs for RRHs have not been adjusted to meet the growth of the hospitals and in some cases; to adapt with the transformation from District General hospitals to Regional Referral hospitals. There is also no standard staffing structure provided to RRHs by the MOH.

Audit Comment Lack of specialised staff limits the ability of RRHs to execute their mandate of offering specialised services.

Recommendations• The MOH is advised to develop staffing structures suitable for the needs of

RRHs.

OVERALL AUDIT CONCLUSIONThe results of the efficiency study of the operations of RRHs using the data envelopment analysis technique have shown that 50% of the RRHs were relatively efficient in the utilization of their resources. The remaining inefficient hospitals exhibited potential for improvements if appropriate interventions were made to address the slacks in the utilization of the key inputs such as medicines, infrastructure, /equipment and human resource.

With reduced inefficiency, RRHs stand to reap significant input savings from their activities. This would ensure improvements in the coverage and quality of health services.

Admissions Patients who undergo a hospital’s formal admission process and may be either an overnight-stay patient or a same-day patient.

Allocative efficiency This occurs when there is an optimal distribution of services, taking into account consumers’ preferences

Maternal Mortality rate Maternal mortality rate is the number of maternal deaths in a population divided by the number of women of reproductive age, usually expressed per 1,000 women.

Outpatient A patient who receives medical treatment without being admitted to a hospital.

Patient days The total number of days stayed by all inpatients during a year.

Standard Unit of Output The SUO is a composite measure of outputs that allows for a fair comparison of volumes of output of hospitals that have varying capacities in providing the different types of patient care services. The standard unit of output attempts to attribute the final outputs of a hospital a relative weight based on previous cost analyses taking the outpatient contact as the standard of reference. The SUO converts all outputs to outpatient equivalents.

Technical efficiency This occurs when a firm is producing the maximum output from the minimum quantity of inputs, such as labour, capital and technology.

Waiting Time The time from when a patient arrives at the hospital to the time of being attended to by a health worker.

APPENDIX III: DETAILS OF DEA THEORETICAL FRAMEWORK.

Illustration of the DEA model

Assuming five hospitals (A, B, C, D & E) with two inputs (for example doctors and money spent on drugs). The following illustrates their usage of the inputs.

A

D

Drug expenditure

In the analysis an input based model is used. That is, the model used assumes that hospitals have little control over varying their outputs than their inputs. Units (A, B, C, D)uses the least amount of resources to produce a given level of output. Combining (envelope) these hospitals makes up what in economics is called an isoquant, or best practice frontier. Since A, B, C and D are on the isoquant the assumption is that the isoquant represents all possible combinations of minimum inputs that can be used to produce a given level of output. It is therefore not possible to reduce the inputs and at the same time produce the given level of output. Turning the focus to hospital E it is obvious that hospital E could reduce the amount of Doctors and Drugs and still be able to produce a given amount of output. Hence E can be considered to be inefficient. When measuring the efficiency we make use of the line between O and E as the direction for potential input savings. The input saving potential is hence represented by the distance between E and E*. Thus in order to become efficient hospital Ecan reduce its inputs to level.

The technical efficiency (TE) scores are computed by comparing the distance between the origin and E with the distance from the origin and E*: T.E = ||OE*||/||OE||. The efficiency score obtained is interpret as the potential reduction in resources. For example, of the efficiency score for hospital E is 0.7 only 70% of the currant resource use is necessary. Only using 70% if E’s input place unit E where E* is located. Multiplying E’s resources use with 0.7 is the same as claiming that the potential is an input reduction with 30%. This implies that in order for hospital E to be efficient, it must save up to 30% (i.e. 100% minus 70%) of their current inputs while still producing the same level of output.

Returns to ScaleReturns to scale (RTS) explains the behaviour of the rate of increase in outputs relative to the associated increase in the input. In the long run all inputs are variable and subject to change due to a given increase in size (scale). A constant return to scale (CRS) implies that a double increase in inputs results in a double increase in the outputs. Production units strive to attain a constant RTS in the long run and therefore this method is applicable where decision making units aim to attain efficiency in the long term.

Variable returns to scale (VRS) implies that a double increase in the inputs results in a more than or less than double increase in the outputs. In the short run, this method is more applicable.

a) Model 1This model uses the same variables as the preferred model but applies floor admissions as a quality measure rather than hospital deaths. This is because floor admissions were thought to be an indicator of quality of health care as suggested by the Hospital directors. The average efficiency scores changes lightly from the preferred model because most of the hospitals report few or no floor admissions. Of interest are Masaka and Mbale RRH which report the highest number of floor admissions in 2011/12 (Masaka) and in 2012/13 (Mbale) resulting in a drop in their average efficiency scores from 100% to 91% and 96% respectively.

b) Model 2This model uses the same variables as the preferred model but applies average length of stay as a quality measure rather than hospital deaths. The average scores generally remain the same for all the RRHs with only marginal changes of 1%-3% for three RRHs from the preferred model results. This model therefore, does not offer unique information.

c) Model 3This model uses the same variables as the preferred model but excludes hospital deaths, therefore leaving quality measures out of the model. There are slight changes in the average efficiency scores of four RRHs while the considerable change is in Soroti RRH which goes from 95% to 100% efficiency. However, this model has not been chosen because disregarding quality results in omitted variable bias as argued by Carey and Burgess (1999)22.

d) Model 4 This model uses the same variables as the preferred model but replaces health workers with total number of staff, therefore incorporating administrative and support staff in the model. This changes the average efficiency score of five RRHs. However, this model has not been chosen because the administrative and support staff are not directly involved in delivering the health service to patients.
