Background. Ischemic stroke incidence is increasing amongst elderly patients in China; this is closely associated with drug-related problems (DRPs). Objectives. To evaluate the influencing factors of DRPs among elderly patients with a history of ischemic stroke in the Chinese community and the role clinical pharmacists play in providing solutions. Materials and methods. This study was conducted in 2 community health service centers in Putuo District, Shanghai, China, between December 2018 and June 2019. Demographics and clinical characteristics of the 130 selected patients were collected. Drug-related problems were classified using the Pharmaceutical Care Network Europe (PCNE)-DRP V8.03 classification system. The number, types, causes, interventions, and status of DRPs were then analyzed. Results. The average number of DRPs per patient was 1.3, corresponding to 256 causes. "Treatment effectiveness P1" was identified as the most common problem (75.0%). The main causes were "drug selection C1" (33.2%) and "patient-related C7" (30.9%). Antihypertensive drugs, statins, aspirin, and Chinese patent medicines were the top 4 drugs for DRPs. Age, unintentional medication discrepancy and medication compliance were independent predictors of DRPs. Pharmacists provided 339 interventions, mainly "at drug level I3" (38.9%) and "at patient level I2" (30.7%). Most of the interventions (85.5%) were accepted by the patients and 65.9% of the problems were solved. Conclusions. The number, types and etiology of DRPs in elderly patients with ischemic stroke in our community are diverse and treatment effectiveness is the main cause of their occurrence. Clinical pharmacists play an important role in providing interventions for major causes of DRPs. [ABSTRACT FROM AUTHOR]
