Diagnostic error reduction in the United States and Italy through the intervention of diagnostic management teams

A major challenge to most countries is the growing cost of healthcare. The cost of laboratory testing is approximately 3% of the total clinical costs. On the other hand, waste from inappropriate admissions to clinical departments is reported to be as high as 15%. A frequently used approach to save dollars in healthcare is the random reduction in the budget for laboratories, with a focus on reduction of the number of unnecessary laboratory tests. The World Health Assembly has approached the problem by publishing a list of essential in vitro diagnostic tests, in order to achieve a global rationalization of the problem. A much more thoughtful strategy to saving healthcare finance is to improve the efficiency of the diagnostic process. This report presents an opportunity to reduce diagnostic error and increase the efficiency of diagnostic testing. Reduction in time to a correct diagnosis provides a major financial as well as a clinical benefit. In addition, reducing both overutilization and underutilization of laboratory tests while achieving the correct diagnosis is a major benefit to challenged healthcare budgets. One approach taken to achieve major savings in healthcare has been the creation of “Diagnostic Management Teams,” composed of experts in specialty areas of medicine who are primarily based in the clinical laboratory to advise physicians on the selection of only necessary tests and the interpretation of complex test results.
