The management of asthma in adult patients in the community pharmacy setting: Literature review

BACKGROUND:Asthma poses a public health concern, with an estimated 235 million people currently living with the condition globally. The provision of evidence-based, patient-centred services for adult asthma patients in community pharmacy which involves collaboration across the multidisciplinary team could improve their asthma control. OBJECTIVES:A literature review was conducted to examine the evidence of asthma management in community pharmacy setting. METHODS:Five databases were searched to identify relevant articles published before February 2021. Screening of the potential studies was performed to remove articles that did not comply with the inclusion criteria. Relevant data from all included studies was collected using a data extraction form to ensure consistency throughout the review. RESULTS:Twenty studies were included in the review; all were conducted in community pharmacy settings in the period of 2001-2020, in different countries. The studies included randomised controlled trials, controlled trials and observational studies. Several successful community pharmacy-based services that were provided to asthma patients to improve their asthma management were highlighted in this review. These interventions consisted of one or more components and included: patient education, inhaler technique improvement, patient counselling, self-management plans, development and provision of asthma action plans and referral to other health care practitioners. None of the studies involved medication or dosage changes by community pharmacy. CONCLUSIONS:The evidence discussed in this review showed that community pharmacists are well-placed to deliver services to asthma patients and many studies were conducted in the community pharmacy to improve asthma control in adult patients. However, further research could be conducted to explore further opportunities for community pharmacy to enhance asthma patients management of their condition.
