Community pharmacists' contribution to public health: assessing the global evidence base

Abstract

In the UK, community pharmacies are more accessible to the general population than general practices. Therefore, government white papers and briefing documents from pharmacy professional bodies have advocated the expansion of the role of community pharmacists, particularly in relation to the provision of services that contribute to disease prevention and health improvement. It is unknown whether the same evidence exists globally for the expansion of these roles. This article attempts to appraise and summarise the global evidence for the public health roles that community pharmacists play. Barriers, as well as strategies that can enhance these roles, are also discussed.Electronic databases were searched to retrieve relevant literature published since 1 January 2000. The selected literature included 2 meta-analyses, 7 literature reviews, 23 interventional studies and 41 descriptive studies. These were assessed according to health topics (i.e. smoking cessation, weight management, health promotion, disease screening and preventive activities, vaccination and immunisation, alcohol dependence advice and drug misuse, emergency hormonal contraception, and sexual health services).The effectiveness of community pharmacy-based public health interventions was shown in smoking cessation, health promotion, disease screening and preventive activities, provision of emergency hormonal contraceptive, and vaccination services. Although there was mixed evidence with respect to weight management and alcohol dependence advice interventions, the available data suggest feasibility and acceptability of these services due to the perceived ease of access and convenience.

A comparative analysis of pharmaceutical workforce development needs across the commonwealth

“…1,2 As medicine experts, pharmacists play a prominent role in preventative care and population health improvement. [3][4][5] Although research has demonstrated that pharmaceutical care interventions enhance therapeutic outcomes, existing literature indicate that pharmacists are often underutilised as health care providers, particularly within the community. 6 The optimal coordination of health services to better utilise pharmacists' accessibility and expertise is needed to ensure that patients' medicines and pharmaceutical care needs are met.…”
