Abstract
Objective: To review the role of pharmacists in educating and monitoring patients with chronic obstructive pulmonary disease (COPD) on inhalation technique. Data Sources: A PubMed search (January 2000 to May 2020) was performed using the following keywords and associated medical subject headings: adherence, chronic obstructive pulmonary disease/COPD, education, inhaler, pharmacist, and technique. Study Selection and Data Extraction: The search was conducted to identify English language articles highlighting the importance of correct inhaler technique in COPD management and benefits of pharmacist inhaler training such as improved adherence, quality of life (QoL), and disease control. Randomized controlled trials, retrospective studies, observational studies, systematic reviews, and meta-analysis reporting pharmacist training were included. Data Synthesis: This review summarizes that incorrect inhaler use negatively affects treatment outcomes, prognosis, and QoL. Pharmacists are in a unique position to educate and monitor patients with COPD on optimal inhaler technique and an individualized, multifactorial approach to COPD management involving pharmacists could provide cost-effective patient care and improve adherence and minimize inhaler misuse. Several strategies used by pharmacists can optimize patient inhaler use, such as face-to-face technique demonstrations, the "teach-back" method, telemonitoring, instructional videos, or informational leaflets. An individualized action plan involving education and regular monitoring of inhaler use further enhances optimal adherence and disease management. Conclusions: As pharmacists are easily accessible to both patients and health care providers, they are ideally placed to play an important role in the enhancement of education on, and continuous assessment of, optimal inhaler technique, thereby improving adherence, disease control, and QoL.
