Abstract
OBJECTIVE
Despite evidence-based guidelines stating that lipase alone should be used in the diagnosis of suspected acute pancreatitis, health care providers continue to order amylase or amylase and lipase together. The purpose of this study was to assess the utilization of appropriate laboratory testing related to the diagnosis of acute pancreatitis.
METHODS
The study used a retrospective cross-sectional design. The timeframe was from January 1, 2020, to December 31, 2020. A retrospective chart review was used to collect data for the following: patient-provider encounter notes, patient demographics, provider demographics, differential and final diagnosis, and laboratory test results. Data analysis include stratification of categorical variables and calculation of cost savings.
RESULTS
For the 12-month period, this study found 2567 (9.3%) of all amylase and lipase tests to be unnecessary. Amylase tests (1881; 73.2%) made up the most unnecessary tests followed by lipase tests (686; 26.7%). An analysis of test-ordering behavior by providers revealed that 81.5% of all unnecessary tests were ordered by MDs. Finally, this study estimated a total cost savings of $128,350 if all unnecessary tests were eliminated.
CONCLUSION
Our study demonstrated that amylase and lipase tests have been overutilized in the diagnosis of acute pancreatitis.
