Drug Utilisation Review among Geriatric Patients with Noncommunicable Diseases in a Primary Care Setting in Malaysia.

Abstract

A prospective cross-sectional study was conducted to analyse the drugs prescribed to the elderly population with noncommunicable diseases and to determine the polypharmacy at a primary care clinic in Negeri Sembilan, Malaysia. The study was conducted for 6 months at the primary care clinic of Gemas. Geriatric patients above the age of 65 and diagnosed with noncommunicable diseases were included upon providing written informed consent. The majority of the geriatric patients were between 65 and 69 years (mean: 69.72 ± 2.85) and prescribed 4 or more medications (mean: 5.18 ± 0.64, p = 0.007). More than 95% (n = 295) of the geriatrics were found to have multimorbidity, in which around 45% (n = 139) had type-2 diabetes together with hypertension and dyslipidaemia. Combination therapy was prescribed to more than 97% (n = 302) of the elderly, whereas cardiovascular and endocrine medications were the most commonly prescribed. Ten prescriptions were found to have drug-related problems, prescribing cascade (80%), lack of medicine optimisation (10%), and inappropriate prescription (10%). In this study, the majority of the elderly had multimorbidity; polypharmacy was commonly seen among geriatric patients. Polypharmacy is the biggest threat to the elderly population, as it increases the chances of falls and fall-related injuries. Medicine optimisation and deprescribing will reduce the chances of drug-related problems and morbidity and mortality associated with polypharmacy and over-consumption of medications. Hence, the study recommends the health fraternity look for medication optimisation and deprescribing to reduce the future complications associated with polypharmacy.
