A study conducted at Meir Medical Center in Israel found that a simple educational intervention on antinuclear antibody (ANA) testing in non-rheumatology departments led to a decrease in the number of unnecessary tests and an increase in the positivity rate. The intervention consisted of 30-minute group sessions emphasizing the risks of ANA testing and the importance of patient selection. After the intervention, departments ordered fewer tests and more results were positive, reflecting better patient selection. The study concluded that such educational initiatives can improve decision-making, reduce excessive ANA testing, and lead to improved diagnostic and treatment processes.
