Abstract

Objective. Textbook outcome (TO) is a composite outcome measure used in surgical oncology to compare hos-pital outcomes using multiple quality indicators. This study aimed to develop TO as an outcome measure to assess healthcare quality for patients undergoing cytoreductive surgery (CRS) for advanced-stage ovarian cancer.Methods. This population-based study included all CRS for FIGO IIIC-IVB primary ovarian cancer registered in the Netherlands between 2017 and 2020. The primary outcome was TO, defined as a complete CRS, combined with the absence of 30-day mortality, severe complications, and prolonged length of admission (>= ten days). Delayed start of adjuvant chemotherapy (>= six weeks) was not included in TO because of missing data. Logistic regressions were used to assess the association of case-mix factors with TO. Hospital variation was displayed using funnel plots.Results. A total of 1909 CRS were included, of which 1434 were interval CRS and 475 were primary CRS. TO was achieved in 54% of the interval CRS cohort and 47% of the primary CRS cohort. Macroscopic residual disease after CRS was the most important factor for not achieving TO. Age >= 70 was associated with lower TO rates in mul-tivariable logistic regressions. TO rates ranged from 40% to 69% between hospitals in the interval CRS cohort and 22% to 100% in the primary CRS cohort. In both analyses, one hospital had significantly lower TO rates (different hospitals). Case-mix adjustment significantly affected TO rates in the primary CRS analysis.Conclusions. TO is a suitable composite outcome measure to detect hospital variation in healthcare quality for patients with advanced-stage ovarian cancer undergoing CRS. Case-mix adjustment improves the accuracy of the hospital comparison.(c) 2023 The Authors. Published by Elsevier Inc.
