Reducing Diagnostic Errors Worldwide Through Diagnostic Management Teams.

ABSTRACT

A major challenge facing most countries is the growing cost of healthcare. Laboratory testing costs constitute approximately 3% of all clinical costs, while waste of funds due to inappropriate admissions to clinical departments is reported to be as high as 15%. A frequently used approach to save money in healthcare is random reduction of laboratory budgets, focusing on decreasing the number of unnecessary laboratory tests. The World Health Assembly has approached this problem by publishing a list of essential in vitro diagnostic tests, to achieve a global rationalization of the problem. A much more thoughtful strategy to reducing healthcare expenditure is to improve the efficiency of the diagnostic process. Decreasing the time to a correct diagnosis provides considerable financial and clinical benefits. Additionally, reducing both overutilization and underutilization of laboratory tests while achieving the correct diagnosis is of great benefit to challenged healthcare budgets. Examining the situation in the United States and Italy, this review presents an opportunity for reducing diagnostic error and increasing the efficiency of diagnostic testing worldwide. One approach taken to achieve major savings in healthcare in the United States, which can be applied in Italy and other countries, is the creation of "diagnostic management teams," comprising experts in specialty areas of medicine, primarily based in the clinical laboratory, who can advise physicians on the selection of necessary tests and the interpretation of complex test results.
