Influence of External Factors on Frozen Section Performance

Background: Pathologists spend their days making decisions, mostly about the significance of histologic features observed during the routine practice of microscopic examination. Recently some have proposed that humans may have an individual capacity for decision-making throughout the day and once exhausted, the quality of this capacity degrades. Here we investigate whether external factors, as suggested by the concept of 'decision fatigue,' may impact upon the ability of a pathologist to render the best possible diagnosis at the time of frozen section (FS).
Design: We evaluated all FS performed within a six-month period at our tertiary level hospital and cancer center. For each FS several features were recorded including the time of day, if the FS diagnosis was discrepant from the final diagnosis and if the diagnosis was deferred at the time of FS. The discrepancies and deferrals were compared to the time of day that they occurred.
Results: Discrepancies and deferrals show a non-uniform frequency throughout the day, which demonstrate a similar pattern of occurrence, showing two periods of increased frequency.
