Randomized controlled trial parallel-group on optimizing community pharmacist’s care for the elderly: The influence of WhatsApp-Email delivered clinical case scenarios

Abstract

Background Drug-related problems (DRPs) significantly threaten the safety of the elderly. In order to improve pharmacists’ ability to minimize these events, novel educational interventions that consider the current challenges in clinical practice are crucial. Objectives The primary objective is to assess the impact of two unique educational interventions on pharmacists’ ability to identify DRPs. Method A total of 127 community pharmacies in the United Arab Emirates (UAE) were recruited and randomly allocated to one of three arms using a 1:1:1 allocation ratio. While a series of clinical case scenarios (N = 24) related to elderly care were established and validated and sent to pharmacists in Active Group A over a 3-month period, lengthy research articles focused on medication safety in elderly were emailed to pharmacists in Active Group B. The control group pharmacist received no intervention. Then, pharmacists self-reported the number, categories, and severity of DRPs and pharmacist recommendations. Results The incidence of DRPs identified by pharmacists was 10.8% in Active Group A, 2.0% in the Control Group (p = 0.011), and 3.8% in Active Group B (p = 0.014). A significant difference was observed in the proportion of DRP types between Active Group A and the Control Group. The most common DRPs in Active Group A were avoidable medication (14.7%) and untreated disease (9.2%). Pharmacists in Active Group A (37.2%) and Active Group B (32.3%) most commonly intervened by recommending the cessation of medication, while the most common intervention in the Control Group was recommending a decrease in dose (29.8%). The mean cost reduction per patient was highest in Active Group A (31.3 ±11.8 $), followed by Active Group B (20.8 ±8.6 $) and the Control Group (19.6 ±9.5 $). The mean time needed to resolve a DRP was shortest in Active Group A (7.3 ±3.5 minutes), followed by Active Group B (9.8 ±4.2 minutes) and the Control Group (9.8 ±5.7 minutes). Conclusion Using WhatsApp to deliver clinical scenarios was effective in improving pharmacists’ ability to identify and address DRPs in elderly patients, resulting in faster resolution and higher cost savings.
