Credentialed pharmacist-led home medicines reviews targeting treatable traits and their impact on health outcomes in people with chronic obstructive pulmonary disease: a pre- and post-intervention study.

Abstract

Patients with chronic obstructive pulmonary disease (COPD) should engage in self-management strategies targeting behavioural traits and lifestyle risk-factors for optimal outcomes. To evaluate the impact of credentialed pharmacist-led home medicines review (HMR) targeting treatable traits (TTs) on health outcomes in COPD in primary care. A pre- and post-intervention study was nested within a cluster-randomised controlled trial. A total of 81 participants with COPD from 21 Australian general practices received an HMR with a credentialed pharmacist targeting TTs. Changes in health outcomes at 6 and 12months from baseline were assessed. Ten TTs were assessed and targeted during the HMR. At baseline, no-one had a written action plan for managing exacerbations, and medication adherence was sub-optimal in 85% of patients. Additionally, 53% of participants demonstrated inadequate inhaler device technique, while 52% were current smokers. At 6-months follow-up, significant improvements were observed in health-related quality of life (St. George's Respiratory Questionnaire score = 34.6 versus 39.1 at baseline, p = 0.006), health status (COPD Assessment Test score = 12 versus 16, p = 0.002), anxiety (Hospital Anxiety and Depression Scale (HADS)-Anxiety score = 2.0 versus 5.0, p < 0.001), depression (HADS-Depression score = 1.0 versus 5.0, p < 0.001), self-reported smoking (47% versus 51.9%, p = 0.031) and treatment adherence (Tool for Adherence Behaviour Screening score = 12.5 versus 10.0, p = 0.002). At 12-months: health status, anxiety, depression, smoking abstinence and adherence to treatment, continued to show statistically significant improvements compared to baseline measurements. HMRs targeting TTs improved health outcomes in people with COPD. Credentialed pharmacists in primary care can work alongside general practitioners to optimise COPD management.
