Impact of an Educational and Laboratory Stewardship Intervention on Inpatient COVID-19 Therapeutics at a Veterans Affairs Medical Center
Background: Accurate and timely prescriptions of COVID-19 therapeutics, laboratory testing, and antimicrobial stewardship have been a challenge throughout the pandemic as new evidence emerges. While universal consultation with infectious disease specialists on patients admitted with COVID-19 is desirable, it is not always feasible due to limited resources.
Observations: In this single-center study, we implemented a combined educational and laboratory stewardship intervention geared toward hospitalist practitioners resulting in improved accuracy of remdesivir and dexamethasone prescriptions, reduced laboratory use of blood cultures, interleukin 6 assay, and Legionella sputum cultures, and a decrease in antibiotic use for patients with mild-to-moderate oxygen requirements over 6 months. These improvements were seen in tandem with decreased reliance on infectious disease consultation.
Conclusions: These efforts support proof of the principle of combined educational and laboratory stewardship interventions to improve the care of COVID-19 patients, especially where infectious disease consultation may not be available or is accessed remotely.
Conclusions
We report improvements in COVID-19 therapeutic prescriptions and the use of antibiotics and laboratory testing over 6 months at the DVAMC. This was correlated with a deliberate COVID-19 educational initiative that included antibiotic and laboratory stewardship interventions with simultaneous decreased reliance on ID consultation. These efforts lend support to the proof of the principle of combined educational and laboratory stewardship interventions to improve the care of COVID-19 patients, especially where ID support may not be available or is accessed remotely.
