Unnecessary test requests on common tests in blood gas and biochemistry test panel
Abstract
Aim: This study aims to evaluate the frequency of unnecessary test requests and the economic burden caused by sodium (Na), potassium (K), and calcium (Ca) tests, which are common in blood gas panels and biochemistry tests.
Materials and Methods: Patients who underwent simultaneous blood gas and biochemistry tests at our hospital between January 2021 and December 2023 were retrospectively reviewed. Using data from the Hospital Information Management System, unnecessary requests were identified and quantified. The cost of the tests was calculated by multiplying the number of unnecessary tests by the Health Implementation Communiqué (SUT) score and the laboratory tender unit price.
Results: A total of 218,257 unnecessary test requests were identified over the three-year period. Compared to 2021, the number of unnecessary tests decreased by 12.9% in 2022 and 15.3% in 2023. The total financial burden of unnecessary requests was calculated as 1.427.749,99 TL.
Conclusions: Our study shows that unnecessary laboratory test requests represent a significant economic burden and that targeted interventions are needed to reduce costs. Measures such as defining diagnostic algorithms and minimum test request times in hospital information management systems, strict follow-up of test request processes and increasing physician awareness may be effective in reducing health expenditures.
