A preliminary diagnosis service provides prospective blinded dual-review of all general surgical pathology cases in an academic practice.

Abstract

Quality assurance of diagnostic accuracy in surgical pathology is an important part of a pathologist's total quality management program. At our academic institution, the quality of diagnostic accuracy is monitored via dual-review of every general surgical pathology case, which accounts for nearly 20,000 cases per year. This comprehensive dual-review is achieved by operating a preliminary diagnosis service, staffed by a senior or board eligible resident. Analysis of a portion of our dual-review data (6300 cases) demonstrates an overall diagnostic concordance rate of 95.4% and a clinical major discrepancy rate of 0.29% between the preliminary diagnosis and staff pathologist diagnosis, comparable to other published rates. The incorporation of a preliminary diagnosis service into our academic surgical pathology practice has proven to be beneficial with regard to quality assurance and resident education. Other academic institutions may similarly benefit from the addition of such a service.
