Factors related to community pharmacists’ intention to provide collaborative deprescribing service for fall-risk medications in older adults: a factorial and theory-based cross-sectional study
摘要
Collaborative deprescribing of fall-risk-increasing medication by community pharmacists and family physicians can reduce falls in older adults. No such exists in Türkiye.
AimTo identify factors related to community pharmacists’ intention (1) to provide collaborative deprescribing service for fall-risk medications in older adults, and (2) to discuss older adults’ potential fall-risk medications with the family physician.
MethodIn this cross-sectional study, a web-based survey was conducted between November 2023 and February 2024 among Turkish community pharmacists recruited using convenience sampling. The questionnaire included items at the respondent level (including a theory of planned behaviour-based questionnaire) and the vignette level (including factorial vignettes). The factors related to their intention to perform two behaviours were evaluated: (1) providing collaborative deprescribing service and (2) discussing older adults’ potential fall-risk medications with the family physician. Multilevel linear mixed-effects models were used.
ResultsBased on responses from 398 community pharmacists (response rate of 93.2%), the intention to provide collaborative deprescribing service was related to their knowledge test score, self-reported rate of older adults served in the community pharmacy (61–80% category), their scores of subjective norm, self-efficacy, and perceived behavioural control (p < 0.05). Community pharmacists’ intention to discuss older adults’ potential fall-risk medications with the family physician was related to being male, younger age, their experience on patient-centred services, their higher scores of subjective norm, self-efficacy, and perceived behavioural control, and lower scores of attitude (p < 0.05). At vignette level, both intentions were linked to having a history of falls and the number of patients waiting in the community pharmacy (p < 0.05).
ConclusionA collaborative deprescribing service for fall-risk-increasing medications in older adults could be implemented by addressing key determinants of community pharmacists’ intention at both respondent and vignette levels, including subjective norm, self-efficacy, perceived behavioural control, attitude, workload-related factors, and patient clinical history.
