Hippocrates: ‘Primum non nocere’

“Life is short, and the Art is long; opportunity fleeting; experience perilous, and decision difficult. ”

“Wherever a doctor cannot do good, he must keep from doing harm.”

460 BC – 377 BC

Hippocrates: Therapeutic Restraint

“To do nothing is sometimesa good remedy. ”

Definition of an ADR

• “Any noxious, unintended and undesired effect of a drug, excluding therapeutic failures, intentional or accidental poisoning, and drug abuse.”

WHO 1969

• Severe ADR �- Immediate discontinuation of suspect drug

- Required resuscitative or antidote treatment- Caused or contributed to hospitalization

- Caused or contributed to death

Adverse Drug Reactions (ADRs)• Type A: predictable, often dose-dependent, e.g. hypoglycaemia with

insulin, bleeding with warfarin, bradykinesia with neuroleptics

• Type B: unpredictable, idiosyncratic e.g. drug-induced skin rash

• Type C: related to duration of treatment or excessive dose e.g. analgesic nephropathy

• Type D: related to critical timing of treatment e.g. teratogenesis with thalidomide

• Type E: related to sudden withdrawal of long-term therapy, e.g. delirium with benzodiazepine withdrawal

Type A events account for > 80% of all ADRs

ADR epidemiology - 1

• 6% of hospital admissions

• 4% of hospital bed-days• Hospital stay in ADR patients 8% longer

• 0.3% of ADRs are fatal• Mortality in ADR patients increased x 19

• Incidence rate increasing with global ageing• Recent USA statistics: 5th highest cause of death

ADR epidemiology - 2

• Approx. 3% of all deaths in Sweden • Median age in men 81 yrs, in women 83 yrs;• Mortality in older ADR patients 7 times greater

than in younger ADR patients• Hospital admissions for ADRs increasing since

1980s

ADR Costs

• Costly++ i.e. > $200 billion in USA per annum

• UK 2004: £706 million (approx. €1 billion) annually (Pirmohamed et al., 2004)

• Netherlands 2011: €94 million per annum on preventable ADR-related admissions (Leendertse et al., 2011)

• Germany 2006-7: €434 million per annum on preventable ADR-related admissions (Rottenkolber et al., 2011)

• 0.5%-1% of total national health budget in Europe

ADR Risk Factors

• Age > 65• Female > Male• Polypharmacy (> 6 medicines/day)• Multimorbid illness (≥ 4 chronic diseases)• Chronic liver disease• Acute, chronic kidney disease (eGFR < 60

ml/min/1.73m2)• Chronic heart failure• Previous ADR• Certain drugs: insulin, anticoagulants, neuroleptics, oral

hypoglycaemic agents, non-steroidal anti-inflammatories

ADR’s in elderly patients: Cork University Hospital

� Prospective study design: July – Nov 2010

� Eligibility: patients ≥ 65 years admitted via ED

� Patients reviewed admission→ discharge

� ADR detection: patient interview, case-note analysis, physician consultation, review of laboratory and other investigations

� WHO-UMC causality criteria

� Discharge letters requested on all in-patients who had an in-hospital ADR (n=135)

� All 135 index hospital admissions were reviewed on the Hospital In-Patient Enquiry portal.

ADR’s in hospitalized older people

• 513 hospitalised patients; ≥ 65 years

• 135 in-hospital ADR’s identified (affecting 26% of

patients)

• 95% were defined as certain/probable

Polypharmacy

Polypharmacy & ADR risk in Older Patients

• ADR rate with 2 daily drugs: 13%

• ADR rate with 5 daily drugs: 58%

• ADR rate with ≥7 daily drugs: 82%

Prybys et al., 2002

Polypharmacy & Major Polypharmacy

Denham MJ, Brit Med Bull 1990

Median number ofdaily drugs taken by older people with acute illness admitted to hospital = 7 (IQR 5-10)

What causes polypharmacy?

R = 0.726

Gilmartin & O’Mahony, 2012

Polypharmacy: new definition

• “The inappropriate pharmacotherapeutic response from doctors to the presence of multimorbidity, usually in an older person, that results in heightened risk of adverse drug reactions and adverse drug events. The presence of 8 or more daily medicinesrepresents a serious risk of adverse drug-related morbidity, which should trigger corrective action.”

O’Mahony, 2012.

Inappropriate Prescribing & ADRs

• Laroche et al. (2007): 2018 pts • Onder et al. (2005): 5152 pts

PIMs not significantly associated with ADRs in older hospitalised patients, using Beers Criteria

ADEs & Inappropriate Drugs

Arch Intern Med June, 2011

Definition of an Adverse Drug Event (ADE)

• “Harm caused by the use of a drug”Nebeker et al., Ann Intern Med, 2004

• Non-trivial ADE �- Immediate discontinuation of suspect drug- Required resuscitative or antidote treatment

- Caused or contributed to hospitalization- Caused or contributed to death

admission and definitely/possibly avoidable

STOPP vs Beers: SummaryAfter adjusting for age, sex, comorbidity, dementia, baseline ADLs, number of medications……

• Clinically significant ADEs were listed in STOPP 2.54 times more often than in Beers criteria

• Risk of a non-trivial, avoidable ADE is increased significantly with STOPP medications (OR=1.85, 95% CI 1.51-2.26, p<0.001)

• Risk of a non-trivial, avoidable ADE is not increased significantly with Beers medications (OR=1.28, 95% CI 0.94-1.72,p=0.11)

STOPP vs. Beers: Conclusion

• STOPP criteria predict ADEs to a significant degree; Beers criteria do not.

• Potentially inappropriate medications (PIMs) according to STOPP criteriarepresent a significant ADE risk factor

GerontoNet ADR Risk Scale: Conclusions

• GerontoNet scale uses co-dependent variables i.e. statistically flawed

• At least 30% of ADRs in the prospective study are not detected by GerontoNet scale

• Cork prospective ADR study study shows poor ADR prediction of GerontoNet scale

• GerontoNet ADR risk scale does not meet the criteria for clinical utility

ADR prevention

• A new ADR risk scale is needed to identify high-risk older patients

• A new ADR Risk in Older People (ADRROP) scale must focus on modifiable ADR risk factors

• Computerized, standardized method of ADR risk assessment is needed

• Demographic imperative (rising at-risk population)

• Economic imperative (health budgets under strain)

ADRs: Demographic Imperative

Interventions to prevent ADRs

• Focus on the high-risk groups i.e. frail elderly with multimorbidity, polypharmacy, renal disease, liver disease

• Must be cost effective• Education of prescribers• Surveillance by clinical pharmacists• Electronic methods of ADR prevention• ADR reporting

Evidence-based ADR prevention

• Pharmacist-led medication review (17 studies): odds ratio 0.64 (95% CI: 0.43 – 0.96) prevents ADR-related admissions

Royal S et al., Qual Saf Health Care 2005(Systematic review and meta-analysis)

• Outpatient geriatric clinic care using Comprehensiv e Geriatric Assessment (one RCT) :odds ratio 0.65 (95% CI: 0.45 – 0.93) prevents serious ADRs (outside hospital)

Schmader KE et al., Am J Med 2004(Randomized controlled trial)

• In-patient structured education programme on ADR re cognition, prevention (one RCT in the rehabilitation setting):odds ratio: 0.61 (95% CI not cited) prevents in-patient ADRs

Trivalle C et al., J Nutr Aging Health 2010(Randomized controlled trial)

Can STOPP & START criteria help to optimise prescribing in older people?

• Improve medication appropriateness?

• Reduce drug costs?

• Reduce incidence of ADRs/ADEs?

STOPP PIM’s: Implications for drug budget in older people

• 338801 persons aged ≥ 70 years in Ireland during 2007• Primary Care Reimbursement database (uses ATC drug

classification)• 30 out of 65 STOPP criteria � PIM prevalence rate of 36%• Main PIM’s were:

- PPI’s at full dose > 8 weeks- NSAID’s for > 3/12- Long half-life BZD’s > 4/12- Duplicate drug classes

• Polypharmacy was the main risk factor for PIM’s• Expenditure on STOPP PIM’s = 9% of total spent on drugs for

persons aged ≥ 70 years in Ireland during 2007)

Take-home messages - 1

• ADR’s in older people represents a major public health problem.

• ADR incidence is increasing in tandem with increased numbers of older people.

• Comorbid illness leading to polypharmacy is the main cause of ADR’s in old age.

Take-home messages - 2

• Pay careful attention to other ADR risk factors, i.e. chronic kidney disease, liver dysfunction, ADL dependency and inappropriate medication.

• Certain higher-risk medicines demand caution, e.g. insulin, anticoagulants, NSAID’s, neuroleptics, sedatives.

• When 1-year life expectancy is < 50%, consider a switch to palliative pharmacotherapy

Sir William Osler (1849 – 1919)

“One of the first duties of thephysician is to educate the masses not to take (inappropriate) medicine.”

“Imperative drugging – the ordering of medicine in any and every malady (i.e. polypharmacy) -is no longer regarded as the chief function of the doctor.”
