Promoting Community Pharmacy Practice for Chronic Obstructive Pulmonary Disease (COPD) Management: A Systematic Review and Logic Model

Breaking down barriers to COPD management in primary care: applying the updated 2023 Canadian Thoracic Society guideline for pharmacotherapy

Chronic obstructive pulmonary disease (COPD) is a highly prevalent yet under-recognized and sub-optimally managed disease that is associated with substantial morbidity and mortality. Primary care providers (PCPs) are at the frontlines of COPD management, and they play a critical role across the full spectrum of the COPD patient journey from initial recognition and diagnosis to treatment optimization and referral to specialty care. The Canadian Thoracic Society (CTS) recently updated their guideline on pharmacotherapy in patients with stable COPD, and there are several key changes that have a direct impact on COPD management in the primary care setting. Notably, it is the first guideline to formally make recommendations on mortality reduction in COPD, which elevates this disease to the same league as other chronic diseases that are commonly managed in primary care and where optimized pharmacotherapy can reduce all-cause mortality. It also recommends earlier and more aggressive initial maintenance inhaler therapy across all severities of COPD, and preferentially favors the use of single inhaler therapies over multiple inhaler regimens. This review summarizes some of the key guideline changes and offers practical tips on how to implement the new recommendations in primary care. It also addresses other barriers to optimal COPD management in the primary care setting that are not addressed by the guideline update and suggests strategies on how they could be overcome.

Chronic Obstructive Lung Disease: Treatment Guidelines and Recommendations for Referral and Multidisciplinary Continuity of Care

Chronic Obstructive Pulmonary Disease (COPD) constitutes a major public health problem, and it is anticipated that its prevalence will continue to increase in the future. Its progressive nature requires a continuous and well-coordinated care approach. The follow-up for COPD should primarily focus on disease screening and control, which includes monitoring of pulmonary function, prevention of exacerbations, identification of aggravating factors and comorbidities, as well as ensuring treatment adequacy and adherence. However, existing clinical practice guidelines and consensus documents offer limited recommendations for the follow-up. In this context, we undertake a review of COPD treatment and the continuity of care recommendations endorsed by several scientific societies. Moreover, we underscore the importance of the involvement of nursing and community pharmacy in this process, as well as the utilization of quality indicators in the provision of care for the disease.

Factors Associated with Patient Trust in the Pharmacy Team: Findings from a Mixed Method Study Involving Patients with Asthma & COPD

Purpose

The pharmacy team has been shifting its role from primarily dispensing medications to providing patient-centred pharmaceutical care. Establishing a trust relation between the pharmacy team and their patients is fundamental for this new role. This study aimed to (i) identify the level of trust in the pharmacy team among patients with asthma and/or COPD, (ii) assess whether the level of trust patients have in pharmacists differs from their trust in pharmacy technicians, and (iii) identify factors that contribute to building trust in the pharmacy team.

Patients and Methods

First, a focus group with six patients with asthma and/or COPD was conducted to explore which aspects they considered significant for establishing trust in the pharmacy team. Subsequently, these insights were used to develop an online questionnaire. A link to the online questionnaire was distributed among patients with asthma and/or COPD. Data were analysed using exploratory factor analyses to identify underlying constructs for trust. Regression analyses were conducted to evaluate whether these constructs affected trust (scale 1-10) in the pharmacy team.

Results

A total of 290 patients completed the questionnaire. On average, they rated their trust in the pharmacy team with a score of 7.4 out of 10 (SD: 1.5), almost identical to their trust in the pharmacist and pharmacy technician. Patient trust in pharmacy teams is influenced by their perception of engagement, expertise in medication-related matters, and effective communication.

Conclusion

Trust in the pharmacy team was observed as moderately high, indicating that there is room for improvement. Due to the changing role of the pharmacy team, its members should strive to enhance their patient-centred skills ensuring ongoing efforts to build and maintain trust with patients.

Effectiveness of Hospital Pharmacist Interventions for COPD Patients: A Systematic Literature Review and Logic Model

Purpose

This review aimed to summarize empirical evidence about pharmacist-led interventions for chronic obstructive pulmonary disease (COPD) patients in hospital settings and to identify the components of a logic model (including input, interventions, output, outcome and contextual factors) to inform the development of hospital pharmacist’s role in COPD management.

Methods

A systematic review of literature retrieved from four English databases (PubMed, Web of Science, Scopus, ScienceDirect) and one Chinese database (CNKI) were conducted to identify eligible studies published from inception to March 2022. Studies concerning pharmacist and COPD were identified to screen for randomized controlled studies that focused on pharmacist interventions for COPD at the hospital setting.

Results

Twenty-nine studies were included in this review. The components of interventions identified were categorized according to the six service domains in the International Pharmaceutical Federation’s Basel Statements, and mainly concerned prescribing, preparation, administration and monitoring but not procurement and training. Extended interventions were also identified including life guidance, psychological counseling, and respiratory function exercise. The most common outputs reported were improvement in medication adherence, rational drug use, level of knowledge, and inhalation technique. The clinical outcomes (symptomatic control, lung function, rates of hospital readmission, length of hospital stay, and adverse drug adverse reactions), humanistic outcomes (quality of life and patient satisfaction), and economic outcomes (drug costs, hospitalization costs, antibiotic costs, and direct costs) were reported only in some studies. The contextual factors mainly included geographical factors, education level of patients, socio-economic factors, and no-smoking policy.

Conclusion

The evidence for hospital pharmacists’ interventions in improving COPD patients’ outcome is growing. However, considering the challenges of COPD management, hospital pharmacists should further leverage the advantages of cross-sector and multi-disciplinary collaboration in order to provide more comprehensive support to better address the needs of their patients.
