ObjectivesThe ProPublica Surgeon Scorecard is the first nationwide, multispecialty public reporting of individual surgeon outcomes. However, ProPublica's use of a previously undescribed outcome measure (composite of in-hospital mortality or 30-day related readmission) and inclusion of only inpatients have been questioned. Our objectives were to (1) determine the proportion of cases excluded by ProPublica's specifications, (2) assess the proportion of inpatient complications excluded from ProPublica's measure, and (3) examine the validity of ProPublica's outcome measure by comparing performance on the measure to well-established postoperative outcome measures.MethodsUsing ACS-NSQIP data (2012-2014) for 8 ProPublica procedures and for All Operations, the proportion of cases meeting all ProPublica inclusion criteria was determined. We assessed the proportion of complications occurring inpatient, and thus not considered by ProPublica's measure. Finally, we compared risk-adjusted performance based on ProPublica's measure specifications to established ACS-NSQIP outcome measure performance (eg, death/serious morbidity, mortality).ResultsProPublica's inclusion criteria resulted in elimination of 82% of all operations from assessment (range: 42% for total knee arthroplasty to 96% for laparoscopic cholecystectomy). For all ProPublica operations combined, 84% of complications occur during inpatient hospitalization (range: 61% for TURP to 88% for total hip arthroplasty), and are thus missed by the ProPublica measure. Hospital-level performance on the ProPublica measure correlated weakly with established complication measures, but correlated strongly with readmission (R = 0.834, P < 0.001).ConclusionsProPublica's outcome measure specifications exclude 82% of cases, miss 84% of postoperative complications, and correlate poorly with well-established postoperative outcomes. Thus, the validity of the ProPublica Surgeon Scorecard is questionable.
