Hospital pharmacist discharge care is independently associated with reduced risk of readmissions for patients with chronic obstructive pulmonary disease: A propensity-matched cohort study

Pharmacist Review of Chronic Inhaler Therapy Appropriateness for Hospitalized Patients with COPD or Asthma

INTRODUCTION

Patients with asthma and chronic obstructive pulmonary disease rely on inhaler therapy to reduce disease progression and exacerbation risk. Patients admitted to the hospital are at an increased risk for exacerbations and readmission if their inhaler therapy upon discharge is not aligned with current guidelines and/or affordable.

OBJECTIVE

Assess the appropriateness of the chronic inhaler regimen for patients admitted to the hospital based on clinical practice guidelines and insurance coverage.

METHODS

A sub-study was designed to analyze a cohort of a single-center, pragmatic, prospective randomized controlled trial at a large academic medical center. Patients admitted to a medicine service with a pharmacist and prescribed a long-acting inhaler were included. Participants randomized to a pharmacist-led intervention were assessed for inhaler appropriateness based on clinical guidelines and patient insurance. The objective of this sub-study is to assess the number of inhalers identified as inappropriate based on the pharmacist's review. A patient was considered to have an inappropriate inhaler regimen if any of their inhalers were inconsistent with guideline recommendations or not covered by insurance. Descriptive statistics were used to characterize appropriate inhaler use.

RESULTS

The study pharmacist reviewed 552 unique inhalers for 348 patients. Overall, 42% of inhalers were inappropriate, affecting 50.3% of participants. 20% of inhalers were inappropriate based on insurance, 26% were inappropriate based on guidelines, and 7% were inappropriate based on both criteria. Recommendations were placed via a pharmacy consult for 198 patients (57%), most recommending an inhaler initiation (55%), followed by inhaler discontinuation (38%).

CONCLUSION

A pharmacist-led review of chronic inhaler therapy for patients admitted to the hospital identified the need for a change in therapy based on financial or clinical guidelines in over half of the patients reviewed. Interventions to increase the appropriateness of prescribed inhalers are needed to reduce disease progression and disease exacerbation.

Insights into British Columbian Hospital Pharmacists Perspectives on the Discharge Process

Background: Transitions of care represent a vulnerable time for patients where unintended therapeutic changes are common and inadequate communication of information frequently results in medication errors. Pharmacists have a large impact on the success of patients during these care transitions; however, their role and experiences are largely absent from the literature. Objectives: The purpose of this study was to gain a greater understanding of British Columbian hospital pharmacists' perceptions of the hospital discharge process and their role in it. Methods: A qualitative study utilizing focus groups and key informant interviews of British Columbian hospital pharmacists was conducted from April to May 2021. Questions asked during interviews were developed following a detailed literature search and included questions regarding the use of frequently studied interventions. Interview sessions were transcribed and then thematically analyzed using both NVivo software and manual coding. Results: Three focus groups with a total of 20 participants and one key informant interview were conducted. Six themes were identified through data analysis: (1) overall perspectives; (2) important roles of pharmacists in discharges; (3) patient education; (4) barriers to optimal discharges; (5) solutions to current barriers; and (6) prioritization. Conclusions and Relevance: Pharmacists play a vital role in patient discharges but due to limited resources and inadequate staffing models, they are often unable to be optimally involved. Understanding the thoughts and perceptions of pharmacists on the discharge process can help us better allocate limited resources to ensure patients receive optimal care.
