Inhalation Innovation: Optimizing COPD Care Through Clinical Pharmacist Integration in a Rehabilitation Hospital's Multidisciplinary Team - A Quality Improvement Study

Abstract

Background: Inhalation therapy is the cornerstone of chronic obstructive pulmonary disease (COPD) management. However, errors frequently occur since every type of inhalation device has different characteristics, complicating their use. The clinical pharmacist is an expert on these devices and can be involved in the care and education of inhaler use in patients with COPD.

Objective: The feasibility of a pharmaceutical care protocol specifically for patients with COPD in a rehabilitation hospital was assessed in a quality improvement study (mixed-methods).

Method: First, the clinical pharmacist had 6 contact moments with hospitalized patients between January and April 2022, which contained appropriateness evaluations and educational moments that were focused on inhalation techniques. Subsequently, a focus group discussion with all involved health care professionals (HCPs) took place to evaluate the preliminary results of the protocol's implementation.

Results: A total of 19 patients entered the study with the protocol resulting in a decrease of critical device errors (38.5% at baseline, to 7.7% at discharge). The HCPs concluded that it was feasible to implement the protocol given certain adjustments. A multidisciplinary collaboration between pharmacists and nurses is necessary to permit the practical implementation, as well as an individualization of the protocol based on the patient's needs. In patient follow-up, transmural care is essential including the HCPs in primary care, and the outpatient clinic.

Conclusion: The evaluation of the protocol by the involved HCPs emphasizes the importance of a clinical pharmacist in the care of patients with COPD as part of the multidisciplinary team, not only in the community or in an acute hospital setting, but also in a rehabilitation hospital.
