Instruments to assess the role of the clinical pharmacist: a systematic review

Abstract

Abstract Background The clinical pharmacist is an essential member of the healthcare team and plays an important role in health care in the primary care and the hospital setting. Knowledge regarding the instruments that evaluate the different activities of the clinical pharmacist, as well as the evaluation of the psychometric properties of these instruments, is necessary. Methods A literature search was performed in the PubMed and Scopus electronic databases without time and language restrictions. For the search strategy, the “pharmaceutical services,” “validity studies,” and “professional performance” domains were used. To assess the quality of the instruments, the five sources of validity evidence of contemporary psychometry were used, and the Joanna Briggs Institute’s standardized instrument was used to assess the methodological quality of the studies. After screening 4096 articles, 32 studies were selected. Results A total of 32 studies were included, and 32 instruments were identified to be used by pharmacists acting in various pharmaceutical practice scenarios. It was found that the available instruments were developed or adapted from others, with variation in the methods, constructs, dimensions, and domains, as well as the psychometric properties. Most of the instruments addressed community pharmacies, and evidence of content validity and internal structure was found most frequently. A standardized and validated instrument that comprehensively assessed the performance of the clinical pharmacist, addressing clinical activities, was not identified for all practice environments. Conclusions Without standardized and validated instruments specifics to assess the performance of the clinical pharmacist, it is hard to establish the main clinical activities performed by pharmacists in their pharmaceutical practice environments and to propose training actions to improve professional practice. Despite the large number of instruments available and considered validated by the authors, it is questioned to what extent the validity indicators presented in the different studies really show the validation status.
