Abstract
Objective: To summarise the findings of an updated
Cochrane review of interventions aimed at improving
the appropriate use of polypharmacy in older people.
Design: Cochrane systematic review. Multiple
electronic databases were searched including
MEDLINE, EMBASE and the Cochrane Central Register
of Controlled Trials (from inception to November
2013). Hand searching of references was also
performed. Randomised controlled trials (RCTs),
controlled clinical trials, controlled before-and-after
studies and interrupted time series analyses reporting
on interventions targeting appropriate polypharmacy in
older people in any healthcare setting were included if
they used a validated measure of prescribing
appropriateness. Evidence quality was assessed using
the Cochrane risk of bias tool and GRADE (Grades of
Recommendation, Assessment, Development and
Evaluation).
Setting: All healthcare settings.
Participants: Older people (≥65 years) with ≥1 long-term condition who were receiving polypharmacy (≥4 regular medicines).
Primary and secondary outcome measures: Primary outcomes were the change in prevalence of appropriate polypharmacy and hospital admissions. Medication-related problems (eg, adverse drug reactions), medication adherence and quality of life were included as secondary outcomes.
Results: 12 studies were included: 8 RCTs, 2 cluster RCTs and 2 controlled before-and-after studies. 1 study involved computerised decision support and 11 comprised pharmaceutical care approaches across various settings. Appropriateness was measured using validated tools, including the Medication Appropriateness Index, Beers’ criteria and Screening Tool of Older Person’s Prescriptions (STOPP)/ Screening Tool to Alert doctors to Right Treatment (START). The interventions demonstrated a reduction in inappropriate prescribing. Evidence of effect on hospital admissions and medication-related problems was conflicting. No differences in health-related quality of life were reported.
Conclusions: The included interventions demonstrated improvements in appropriate polypharmacy based on reductions in inappropriate prescribing. However, it remains unclear if interventions resulted in clinically significant improvements (eg, in terms of hospital admissions). Future intervention studies would benefit from available guidance on intervention development, evaluation and reporting to facilitate replication in clinical practice.
