Implementation of Pharmaceutical Care Services During the COVID-19 Pandemic Worldwide

Background: This study sought to research the implementation of pharmaceutical care services and review the pharmaceutical care services used for coronavirus disease 2019 (COVID-19) prevention, diagnosis, therapy, and vaccination during the COVID-19 pandemic. Methods: All articles reporting pharmacists’ implementation of pharmaceutical care services during the COVID-19 pandemic were comprehensively searched in PubMed/Medline, Embase, and the Cochrane Library databases up to July 7, 2021, then included in this study. Twenty-four items of pharmaceutical care services were classified into the following 5 categories: patient evaluation and monitoring, clinical decision support, compounding/dispensing/administration, patient consultation and education, and drug-related policy research and development. Results: A total of 674 articles from 100 countries were included, with the United States of America being the most frequently studied country. Across the 5 classified categories, compounding/dispensing/administration was most frequently examined (28.9%), followed by patient consultation and education (25.2%). Among the 24 items of pharmaceutical care services, medicine supply management was most frequently reported on (11.4%), followed by patient consultations (11.0%). The primary implemented pharmaceutical care services for COVID-19 prevention, diagnosis, therapy, and vaccination were public health education, COVID-19 testing services, medicine supply management, and vaccination, respectively. Conclusion: Pharmacists have implemented diverse pharmaceutical care services for COVID-19 prevention, diagnosis, therapy, and vaccination globally. Further studies should be conducted to determine the correlation between the characteristics of healthcare accessibility in a country and the implemented pharmaceutical care services for COVID-19.
