A multifaceted stewardship intervention helps curb steroid overprescribing in hospitalized patients with acute exacerbations of COPD

Purpose: Corticosteroid overprescribing is well documented in real-world practice. There is currently no evidence to guide best practices for steroid stewardship. The aim of this study was to assess the effects of a 3-part stewardship intervention strategy on inpatient steroid prescribing in patients with acute exacerbations of COPD (AECOPD).

Summary: Investigators implemented a 3-part stewardship initiative consisting of (1) an anonymous survey for providers on steroid prescribing in a simplified case of AECOPD, (2) face-to-face education and review of survey results, and (3) prospective audit and feedback from a clinical pharmacist. This was a quasi-experimental before-and-after study evaluating hospitalized adults diagnosed with AECOPD in two 12-month study periods before (April 2019-March 2020) and after (May 2020-April 2021) implementation. The primary outcome was mean inpatient steroid dosing. Secondary outcomes were duration of therapy, length of stay (LOS), 30-day readmissions, 30-day mortality, and incidence of hyperglycemia. Per power analysis, there were 27 patients per cohort. The interventions resulted in a significant reduction in prednisone equivalents during hospitalization: 118 mg vs 53 mg (P = 0.0003). This decrease was similar in ICU (160 mg vs 61 mg, P = 0.008) and non-ICU (102 mg vs 49 mg, P = 0.004) locations. There was no significant difference in duration of therapy (8 days vs 7 days, P = 0.44), length of stay (3.3 days vs 3.9 days, P = 0.21), 30-day mortality (4% vs 7%, P = 0.55), 30-day readmissions (15% vs 7%, P = 0.39), or rate of hyperglycemia (48% vs 44%, P = 0.78).

Conclusion: A multifaceted stewardship intervention significantly reduced steroid dosing in hospitalized AECOPD patients. This reduction was not associated with known deleterious effects.
