Reports of surgical outcomes for Cushing's disease are mostly limited to single-center experiences by expert surgeons. Therefore, no generalizable surgical outcome metrics for endoscopic endonasal Cushing's disease surgery are available for practitioners to guide quality-improvement efforts. This is potentially problematic, given the high morbidity and excess mortality observed in patients who do not achieve remission. This study proposes a bundle of evidence-based metrics for low-risk patients with Cushing's disease, for whom optimal outcomes would be expected, that focus on the cost efficiency of care and surgical outcomes from multicenter collaboration of US pituitary centers. The steering committee of the Registry of Adenomas of the Pituitary and Related Disorders (RAPID) consortium proposed the metrics based on available data from 12 US pituitary centers. A benchmarking population of low-risk patients undergoing first-time surgery was identified. Patient characteristics and outcomes were aggregated and analyzed by a data coordinating center. Metrics were reported using 2 approaches. A total of 431 patients from 12 centers who underwent primary endoscopic transsphenoidal surgery from January 1, 2006, to December 31, 2022, were included. There were 227 patients in the low-risk cohort (age < 70 years, BMI < 50, microadenoma, and Knosp grade 0-2). For the cost-efficiency metrics, the mean (SD) length of stay was 3.8 (4.8) midnights, and the percentage of patients readmitted was 11.1%. The rate of disposition to a skilled nursing facility was 2.2%. For surgical outcomes, the rate of postoperative CSF leakage was 1.3%, and the rate of 1-year sustained surgical remission was 81.2%. The rates of permanent and temporary arginine vasopressin deficiencies were 1.8% and 11.9%, respectively. The 75th percentile performance by center was 3.0 midnights for length of stay, 6.3% for 90-day unplanned readmission, < 1% for disposition to a skilled nursing facility, < 1% for CSF leakage, and 92.2% for 1-year sustained remission. The 75th percentile was < 1% for both permanent and temporary arginine vasopressin deficiencies. An evidence-based bundle of metrics in a Cushing's disease patient population at low risk who underwent first-time endoscopic pituitary surgery is proposed. Surgeons can use these metrics to assess and improve the quality of their clinical pathways.
