Impact of an anemia diagnostic management team on follow-up test ordering by primary care providers.

BACKGROUND: Anemia is a complex condition with diverse causes and poses diagnostic challenges amid the expanding landscape of laboratory testing. Implementation of an anemia diagnostic management team (DMT) can aid health care providers in navigating this complexity. METHODS: This quasi-experimental study assessed the impact of an anemia DMT on laboratory test ordering by primary care providers for anemic patients. This study included adult patients (≥18 years) with anemia (hemoglobin <12.0 g/dL for nonpregnant women, hemoglobin <13.0 g/dL for men) presenting to a family medicine clinic. Cases reviewed by the DMT (n = 100) were compared with a control group (n = 95). RESULTS: The DMT recommended additional testing for 76 patients. Significantly more patients in the DMT group underwent follow-up tests compared with controls (59% vs 34%; P < .001). Moreover, the DMT group underwent a higher mean number of tests per patient (1.70 ± 2.2 vs 0.95 ± 1.9; P = .01). CONCLUSION: Implementation of an anemia DMT influenced follow-up testing patterns in anemic patients, potentially enhancing diagnostic thoroughness and patient care.

Assessment of appropriate use of amylase and lipase testing in the diagnosis of acute pancreatitis at an academic teaching hospital.

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.
