Perceptions and expectations of health professionals regarding hospital pharmacy services and the roles of hospital pharmacists: A qualitative systematic review and meta-synthesis.

Background: Pharmacists have become increasingly integrated within the interprofessional hospital team as their scope of practice expanded in recent decades. However, limited research has explored how the roles of hospital pharmacists are perceived by other health professionals.

Aim/objectives: To identify what is known about the perceptions of hospital pharmacists' roles and hospital pharmacy services held by non-pharmacist health professionals.

Methods: A systematic literature search was conducted in August 2022 in MEDLINE, Embase, and CINAHL to identify peer-reviewed articles published between 2011 and 2022. Title/abstract and full-text screening, by two independent reviewers, identified eligible articles. Inclusion criteria included qualitative studies in hospital settings that reported perceptions regarding the roles of hospital pharmacists held by non-pharmacist health professionals. Data were extracted using a standardised extraction tool. Collated qualitative data underwent inductive thematic analysis by two independent investigators to identify codes, which were reconciled and merged into over-arching themes through a consensus process. Findings were assessed to measure confidence using the GRADE-CERQual criteria.

Results: The search resulted in 14,718 hits. After removing duplicates, 10,551 studies underwent title/abstract screening. Of these, 515 underwent full-text review, and 36 were included for analysis. Most studies included perceptions held by medical or nursing staff. Hospital pharmacists were perceived as valuable, competent and supportive. At an organisational level, the roles of hospital pharmacists were perceived to benefit hospital workflow and improve patient safety. Roles contributing to all four domains of the World Health Organization's Strategic Framework of the Global Patient Safety Challenge were recognised. Highly-valued roles include medication reviews, provision of drug information, and education for health professionals.

Conclusion: This review describes the roles hospital pharmacists performed within the interprofessional team, as reported by non-pharmacist health professionals internationally. Multidisciplinary perceptions and expectations of these roles may guide the prioritisation and optimisation of hospital pharmacy services.
