Reduction in Unnecessary Clinical Laboratory Testing Through Utilization Management at a US Government Veterans Affairs Hospital.
OBJECTIVES To implement an electronic laboratory utilization management system (laboratory expert system [LES] to provide safe and effective reductions in unnecessary clinical laboratory testing. METHODS The LES is a set of frequency filter subroutines within the Veterans Affairs hospital and laboratory information system that was formulated by an interdisciplinary medical team. RESULTS Since implementing the LES, total test volume has decreased by a mean of 11.18% per year compared with our pre LES test volume. This change was not attributable to fluctuations in outpatient visits or inpatient days of care. Laboratory cost savings were estimated at $151,184 and $163,751 for 2012 and 2013, respectively. A significant portion of these cost savings was attributable to reductions in high volume, large panel testing. No adverse effects on patient care were reported, and mean length of stay for patients remained unchanged. CONCLUSIONS Electronic laboratory utilization systems can effectively reduce unnecessary laboratory testing without compromising patient care.
