Abstract
BACKGROUND
Healthcare quality measures are metrics that quantify medical outcomes. There is a need for performance indicators in the diagnosis of melanocytic neoplasms. We sought to determine whether the atypical to malignant diagnosis ratio (AMR) and benign to malignant diagnosis ratio (BMR) could identify differences between practitioners within a group as well as individual diagnostic drift.
METHODS
Diagnoses of melanocytic neoplasms from 2013 and 2014 by two dermatopathologists were prospectively subclassified as benign, atypical or malignant and reported on a monthly basis to the pathologists. Case diagnoses of melanocytic neoplasms from 2012 and 2009 were retrospectively subclassified as benign, atypical or malignant for comparison.
RESULTS
A total of 33,169 cases were used in this study. Interpathologist AMR and BMR were significantly different. One pathologist demonstrated a significant increase in AMR over time.
CONCLUSION
AMR and BMR metrics are potential performance indicators that can measure pathologist uncertainty, identify diagnostic drift and provide a surrogate measure of the relative risk level of laboratory patient populations. If applied to multiple laboratories, AMR and BMR metrics could help inform physicians' choice of dermatopathology laboratory and provide a method for comparative analysis between laboratories.
