Deprescribing Antipsychotics and Proton Pump Inhibitors in Long-Term Care: A Prescribing Portraits Approach.

INTRODUCTION

Antipsychotics (APs) and proton pump inhibitors (PPIs) are commonly prescribed in long-term care (LTC) despite potential risks with prolonged use.

OBJECTIVE

This study evaluates the frequency of AP and PPI prescriptions and assesses the impact of "prescribing portraits" on deprescribing in LTC residents at 2 LTC facilities in British Columbia.

METHODS

This multicenter, prospective quality improvement (QI) study was conducted at two LTC homes: Holy Family Hospital (site A) and Queen's Park Care Centre (site B). The QI approach involved collecting data on prescribing appropriateness, implementing a real-time intervention, and tracking its impact. Prescribing portraits-personalized reports detailing individual prescribing patterns, evidence-based indications, and deprescribing recommendations-were presented to prescribers by clinical pharmacists. The primary outcomes were the proportion of prescriptions eligible for deprescribing and the deprescribing rate at 3 months post-intervention.

RESULTS

At site A, 21 of 48 residents receiving AP were identified as eligible for deprescribing, with 31.6% receiving deprescribing orders within 3 months. Among 12 residents previously assessed in our earlier QI study at site A who remained on PPIs, 33% were newly deprescribed after reassessment in this study. At site B, 23 of 48 residents on antipsychotics were eligible, with a deprescribing rate of 20%. For PPIs, 31 of 38 residents were considered eligible at site B, and 36% had deprescribing orders initiated.

CONCLUSIONS

Integrating prescribing portraits into multidisciplinary medication reviews promotes appropriate deprescribing of APs and PPIs in LTC, encouraging safer prescribing practices and improving medication safety.
