In‐hospital deprescribing in the real world – a clinician‐led approach to hyperpolypharmacy

Abstract

AbstractBackgroundA lack of clear guidelines for medication cessation has contributed to the proliferation of polypharmacy. Hospitalisation provides a unique opportunity for initiating deprescribing. Deprescribing interventions are usually pharmacist‐ or multidisciplinary team‐led and are typically safe and beneficial for patients. However, few studies have explored interventions that are implementable by clinicians at the bedside.AimTo explore the efficacy and feasibility of a clinician‐led deprescribing intervention on an acute general medicine ward.MethodA multifaceted intervention was implemented comprising (a) education sessions on deprescribing and (b) a deprescribing alert in the bedside folders of patients with hyperpolypharmacy (>10 medications). Using a historical cohort study design, data from the intervention cohort were compared to a historical control group. A subset of the intervention cohort was surveyed after discharge regarding attitudes toward deprescribing.ResultsWe recruited 1333 patients and had complete data for 1169 (nintervention = 888, ncontrol = 281). The prevalence of hyperpolypharmacy decreased from 28% to 26% in the intervention cohort, but this reduction was not statistically significant (net change = −1, interquartile range [IQR] = −2–0; p = 0.26). There was similarly no statistically significant change in medication numbers due to the intervention across other subgroups. Most patients agreed they were taking too many medications and supported deprescribing.ConclusionsDespite observing no statistically significant effect of the intervention, we demonstrated the feasibility of introducing clinician‐led deprescribing interventions in resource‐poor, busy inpatient units. Simple, innovative deprescribing interventions in hospital settings, along with the measurement of long‐term patient outcomes and medication adverse effects, should be investigated further in large inpatient cohorts.
