Diagnostic errors out-paced errors in obstetrics, and were costlier than surgical cases in the newest annual CRICO Benchmarking Report. In the five-year period studied, 57 percent of the diagnosis-related malpractice cases from across the country arose in the ambulatory setting. By far, the diagnosis most commonly missed was cancer. And the benchmarking data indicate that improvements should zero in specifically on differential diagnosis, test interpretation, and follow-up of consults. This podcast features interviews with diagnosis experts and CRICO leadership.
