- Description
- People with dementia (PWD) are at risk for medication-related harm due to their impaired cognition and frequently being prescribed many medications. This study evaluated a medication safety intervention (including pharmacist medication reconciliation and review) for PWD during an unplanned admission to hospital. This article reports the effect of the intervention on polypharmacy, potentially inappropriate medications (PIMs), and anticholinergic burden scores for PWD. A pre-post design using an intervention site and a control site was conducted in 2017-2019, in a regional area in New South Wales, Australia. Polypharmacy, PIMs, and anticholinergic burden were measured at admission, discharge, and three months after discharge. There were 628 participants including 289 at the control site and 339 at the intervention site. Polypharmacy was 95% at admission and 90% at discharge. PIMs at admission were 95-98% across timepoints and decreased significantly at discharge. The mean anticholinergic score decreased significantly between admission (2.40-3.15) and discharge (2.01-2.57). Reduced PIMs at discharge were correlated with reduced anticholinergic burden (rho = 0.48-0.55, p < 0.001). No significant differences were identified between the study and control sites for Polypharmacy, PIMs, and anticholinergic burden rates and scores. High rates of polypharmacy and PIMs in this study indicate a study population with multiple comorbidities. This intervention was feasible to implement but was limited due to difficulty recruiting participants and deaths during the study. Future multisite studies should be designed to recruit larger study samples to evaluate interventions for improving medication safety for PWD and improve outcomes for these vulnerable people.
