What is economic burden?
The economic cost to the nation associated with expenditures on a disease preventive, screening
and treatment services,
the economic cost associated with time and effort spent by patients and their families undergoing
treatment and the economic cost associated with lost productivity due to disease-related disability
and premature death.
The cost-of-illness (COI) study
One approach to estimating this burden is the Cost-of-Illness study, that uses various national level data sources to obtain estimates of these various components
It is very rare to find cost studies of oral care employing the COI approach
Why study economic burden of a disease? http://www.who.int/choice/economicburden/en/
Statistics on morbidity and mortality of disease help estimate the burden of disease in populations, however they provide an incomplete picture of the adverse impact of ill health on human welfare.
In particular, the economic consequences of poor health can be substantial. E.g. impact of ill-health on a household’s income or a firm’s profits, or the aggregate impact of a disease on a country’s current and future gross domestic product (GDP).
Uses of economic burden studies
Useful for planning health budgets Comparisons of strategies
Basis for priority setting
Projection of future cost of programmes
Convince administrators and policy-makers of the magnitude of burden associated with a particular disease
For example, diabetes and cardiovascular diseases exert considerable economic impacts on health care systems, societies and the individual patients through the need for continued care and loss of productivity - prevention is “cheaper” than cure
Treatment of oral diseases account for the fourth most expensive disease in many industrialised countries, and costs are often borne by patients’ out-of-pocket payments [Petersen et al 2005].
While cost-related studies in oral healthcare are fewer compared to medical care, cost-of-illness (COI) studies of oral diseases are extremely rare [Fardal et al 2012, Ide et al 2009]
Periodontitis is an established and widespread chronic disease, yet its burden on healthcare costs remain largely neglected.
Most studies estimating costs of periodontal care focus on cost of specific periodontal treatment modalities but not the cost of managing the whole spectrum of the disease itself [Braegger 2005, Gjermo & Grytten 2009, Heasman et al 2011]
The neglected burden of periodontal diseases
Periodontal diseases, like any other oral conditions, on their own do not cause death.
However, its known links with known non-communicable diseases such as diabetes and cardiovascular diseases (Chapple et al 2013, Schenkein & Loos 2013) increases its role in contributing to the disease burden of these systemic conditions which may bring about fatality.
A recent review of periodontitis patients dental records in Malaysia indicated that at least a quarter of these patients suffer from diabetes mellitus and hypertension (Tuti et al 2014).
Jeffcoat, M., et. al., Periodontal Therapy Improves Outcomes in Systemic Conditions, 2014
A considerable amount of medical resources is being used for managing DM, PD and their several complications that can occur. A healthy mouth could mean thousands in healthcare savings!
The Increasing Global Burden of Periodontitis [Marcenes et al 2013]
• Oral diseases affect 3.9 billion people worldwide
• 291 diseases and injuries: Severe periodontitis (CPI=4, CAL 6 mm or a gingival pocket depth of >5 mm) is ranked 6th (11%) – higher than cardiovascular diseases.
• In the same study, severe periodontitis has been cited to have a mean disability-adjusted life years (DALYs) which was ranked at number 77. Disability was defined as “bad breath, a bad taste in the mouth, and gums that bleed a little from time to time”
In 2010, about 94.0% of Malaysian adults have periodontal disease
30.3% have shallow pockets (CPI=3)
18.2% have deep pockets (CPI=4)
• This is translated into a total of 48.5% of the adult population with periodontitis, or an estimated quantum of 11.5 million adults!
Study rationale
An estimate of economic burden of managing periodontitis will assist in allocation of resources and provide an economic framework for evaluation of related healthcare programmes
Aim of study
• To estimate the economic burden associated with the specialist management of periodontitis in Malaysia from the societal perspective.

Tuti et al 2014. Cost analysis of Periodontitis management in public sector specialist dental clinics BMC Oral Health 14:56
Methods (2) : Patient recruitment and one-year periodontal therapy at specialist clinics
Methods (3): Cost analysis
Conducted from the societal perspective: the economic viewpoint of the provider, Ministry of Health, Malaysia, and the patients
Employed two costing methods: the step-down and activity-based costing (ABC) methods, which were substantiated by a clinical pathway.
The scope of costs included resources consumed for 30 procedures classified into diagnostics, non-surgical periodontal therapy and surgical interventions performed for periodontitis patients
Methods (4): Cost components

Direct cost Indirect cost
Dental procedures
including diagnostic
tests (equipment,
supplies, time taken,

Programme
administration, physical
space, utilities (water,

patients’ out-of-pocket
expenses (meals,
travels, etc)
Time spent by patient
seeking care (work
days/ hours lost)
Total cost per procedure = dental equipment cost + dental consumables cost+ staff salary + administrative cost (building, traveling, staff training, utilities, professional services, printing, hospitality, cleaning and sterilisation services)
Methods (5): Sources of cost data
Provider cost: clinic, annual returns, administrative and financial record for year 2011, as well as observation of 60 patients undergoing various treatments.
Patient cost: diaries provided primary data for patient out-of-pocket expenditures and time taken off work, whenever applicable, for a period of twelve months after being recruited into the study

Provider cost per outpatient visit = Capital cost + Recurrent cost Capital cost = Building cost + Equipment cost (≥RM 500) Recurrent cost = Utility cost + maintenance cost + staff emolument and benefits + stocks and dental consumables/ supplies cost + drug cost
Patient cost per outpatient visit = Transportation cost + meals and beverages cost + clinic fees + productivity loss + others (crèche etc.).

Study insights Periodontitis is a disease which seems unassuming in nature when it is at an early stage.
Because of this, most patients will not appreciate the need to seek early treatment.
Because of this, policymakers will not appreciate and address the potential impacts or threats of this disease.
Measuring the economic burden imposed by periodontitis on society as a whole means quantifying the consumption of health care resources and production losses incurred by the disease.
Conclusions
This study validates the longstanding hypothesis that a heavy economic burden is imposed on health care systems and the society to provide care for patients with periodontitis. It is comparable and even higher than economic burden of some chronic diseases in the country.
The more severe, the greater the need, the greater the economic burden!
Interpretation of findings is limited by the scope (specialist care, public sector) and duration of the study (first year of treatment)
Recommendations
Raise awareness among policy-makers and the public about the negative economic impact of periodontitis
Further emphasise the need for oral disease prevention and oral health promotion.
Focus on primary prevention and early detection of signs and symptoms reinforced and targeted to the younger age group.
Closing thoughts With such an economic burden higher than the health budget itself, and so many health needs of the population to cater for, no country will be able to meet these periodontal treatment needs
As it is, utilisation of public sector dental clinics including specialist periodontal clinics among adults is already very low.
It is clear that many patients have been or will be left under-treated or untreated and will potentially suffer the negative consequences
It is our collective responsibility to solve this problem
