Abstract
The impact of several pharmaceutical interventions to reduce the use of potentially inappropriate medications (PIMs) and potentially omitted medications (POMs) has been recently studied. We aimed to determine whether clinical medication review (CMR) (i.e. a systematic and patient-centred clinical assessment of all medicines currently taken by a patient) performed by a geriatrician and a pharmacist added to standard pharmaceutical care (SPC) (i.e. medication reconciliation and regular prescription review by the pharmacist) resulted in more appropriate prescribing compared to SPC among older inpatients. A retrospective observational single-centre study was conducted in a French geriatric ward. Six criteria for appropriate prescribing were chosen: the number of PIMs and POMs as defined by the STOPP/STARTv2 list, the total number of drugs prescribed, the number of administrations per day and the number of psychotropic and anticholinergic drugs. These criteria were compared between CMR and SPC group using linear and logistic regression models weighted on propensity scores. There were 137 patients included, 66 in the CMR group and 71 in the SPC group. The mean age was 87years, the sex ratio was 0.65, the mean number of drugs prescribed was 9, the mean MMSE was 21 and at admission 242 POMs, and 363 PIMs were prescribed. Clinical medication review did not reduce the number of PIMs at discharge compared to SPC (beta = - 0.13 [- 0.84; 0.57], p = 0.71) nor did it reduce the number of drugs prescribed (p = 0.10), the number of psychotropic drugs (p = 0.17) or the anticholinergic load (p = 0.87). Clinical medication review resulted in more POMs being prescribed than in standard pharmaceutical care (beta = - 0.39 [- 0.72; - 0.06], p = 0.02). Cardiology POMs were more implemented in the medication review group (p = 0.03). Clinical medication review did not reduce the number of PIMs but helped clinicians introduce underused drugs, especially cardiovascular drugs, which are known to be associated with morbidity and mortality risk reduction.
