Abstract:
Serial monitoring of plasma cytomegalovirus (CMV) viral load monitoring with intervals of less than five days or using different assays for monitoring may cause unnecessary budgets for laboratory testing without changes in treatment, morbidity, and mortality. Methods The pre-intervention retrospective study and post-intervention prospective cohort study were performed. In 2021, the inpatient electronic pop-up and telephone interview and feedback were used to limit unnecessary plasma CMV viral load testing. The rate of plasma CMV viral load testing being performed with intervals of less than five days was compared before and after protocol implementation using the Poisson regression model. The cost-effectiveness of plasma CMV viral load testing after protocol implementation was also studied. Results After protocol implementation, there was a significant decrease in the rate of plasma CMV viral load test requests with intervals of less than five days from 11.8% to 6.2% [Incident rate ratio (IRR) 0.50, p-value & lt; 0.001]. Of these, 38.9% was due to unintentional requests. After telephone interviews the rate of plasma CMV viral load test requests with intervals of less than five days decreased further to 4.7% (IRR 0.37, p-value & lt; 0.001). The costs of plasma CMV viral load testing performed with intervals of less than five days and anti-CMV drugs were reduced significantly.

This program should be maintained, and an electronic hard stop alert program should be developed. Disclosures All Authors: No reported disclosures.
