Appropriate Long Term Prescribing and Polypharmacy Alpana Mair Dr Gregor Smith
Some Background: The ageing population • 62% projected rise in over 65s 2006-31 • 144% projected rise in over 85s 2006-31 • Increased prevalence of LTC, esp COPD and Diabetes • 24% projected rise in older people admitted as emergencies by 2016 • Would require an extra £3.5 billion 2031 Audit Scotland
Multiple Morbidities • “Multiple conditions”: presence of 2 or more LTC • Largely the norm but associated with poorer outcomes • More people in Scotland with MM below 65 years than above • Develops around 10 years earlier in deprived areas • Associated with more medical errors

Contributory Factors • AGE • Non age factors that contribute to developing polypharmacy include: • Multiple morbidities • Residence in long term care home • Hospitalisation, esp repeat episodes of care • Patient expectation • GP attitude • Consultation with several doctors
Polypharmacy: associated dangers • Adverse drug event • Confusion • Falls • Interactions • Drug – drug Interaction • Drug – Disease Interaction • Poor compliance and concordance
Drugs commonly associated with admissions due to ADR • NSAIDs 29.6% • Diuretics 27.3% • Warfarin 10.5% • ACE 7.7% • Antidepressants 7.1% • Beta blockers 6.8% • Opiates 6.0% • Digoxin 2.9% • Prednisolone 2.5% • Clopidogrel 2.4%
High Risk Combinations • NSAID plus any of: • ACE or ARB + diuretic (triple whammy) • eGFR <60 • Diagnosis heart failure • Warfarin • Age >75 without PPI
High Risk Combinations • Warfarin Plus any of: • Another antiplatelet • NSAID • Macrolide • Quinolone • Metronidazole • Azole antifungal
High Risk Combinations • Heart Failure diagnosis plus any of: • Glitazone • NSAID • Tricyclic antidepressant
Drugs Poorly Tolerated in the Elderly • Digoxin (doses higher than 250mcg) • Antipsychotics • Tricyclic antidepressants • Benzodiazepines • Anti cholinergics • Phenothiazines • Combination painkillers
Special considerations • Orthostatic hypotension • Shared side effects eg sedation, bleeding • Diabetic treatment; optimal HbA1c • Antipsychotic medication • Laxatives • Shortened life expectancy
Drugs which can be associated with rapid symptomatic decline if stopped • ACE inhibitors in heart failure / LVSD • Diuretics in heart failure • Steroids • Drugs for heart rate or rhythm control • Anticonvulsants for epilepsy • Antidepressant, antipsychotic, mood stabilisers • amiodarone • Drugs for managing Parkinson’s Dis • Disease modifying anti-rheumatic drugs With caution With specialist advice
CEL 36: November 2012 • Appropriateness of long term prescribing • At medicines review • On starting new medicines • First iteration of National Guidance • Aim – to improve therapeutic care by reducing the risk of adverse drug reactions associated with polypharmacy
GMS Contract 2013 / 14 • Unique negotiated settlement in Scotland • QPQOF – High Risk Patients • Anticipatory Care Plans • Polypharmacy Review • Multi-disciplinary approach • SPARRA risk score 40-60% • 0.75% practice popn 1st yr, rising to 1.5% 2nd yr
