Corticosteroid Prescribing Patterns in the Emergency Department for Acute COPD Exacerbations: A Retrospective Analysis Following an Educational Intervention.

Introduction: COPD is a progressive lung disease with marked airflow limitation. It has a large global prevalence and is managed with antibiotics, bronchodilators, and corticosteroids. Despite the prevalence, corticosteroid prescribing regimens differ widely amongst providers. This study aims to evaluate baseline corticosteroid prescribing patterns, the ability to change corticosteroid prescribing patterns with the utilization of an educational initiative, and to evaluate the effect of corticosteroid dose on length of stay, 30-day hospital readmission, mortality, and total hospital insulin dosing.

Methods: This study was conducted via a retrospective observational study. Providers at a single institution answered a baseline questionnaire on COPD corticosteroid prescribing patterns and subsequently received an educational presentation regarding evidence-based corticosteroid recommendations. Data were then retrospectively obtained and analyzed evaluating corticosteroid prescribing patterns both pre- and post-educational intervention. Data were analyzed using IBM SPSS Version 25.

Results: The provider survey revealed that most (95.3%) administered 125 mg of methylprednisolone to patients treated for AECOPD. The most common reason a particular dose of corticosteroid was administered was due to previous teaching or practice patterns. The mean initial steroid dose of methylprednisolone decreased following the educational initiative from 114.24 mg to 72.8 mg (p < 0.01). This corresponded to a 69% (n=41) decrease of providers using 125 mg methylprednisolone (p < 0.01), and increased prescribing of 62.5 mg methylprednisolone by 42.6% (n=66). The mean LOS following hospital admission for AECOPD in the pre-intervention group was 5.80 days, while the mean LOS following the targeted educational intervention decreased to 4.82 days (p = 0.01).

Conclusions: The implementation of an educational intervention may change provider corticosteroid prescribing patterns. Additionally, lower corticosteroid dose in the Emergency Department may decrease patient length of stay. Keywords: Corticosteroid, COPD, LOS, recommendations, steroid.
