Textbook Outcomes in Liver Transplantation.

Background: Textbook outcome (TO) is an emerging concept within multiple surgical domains, which represents a novel effort to define a standardized, composite quality benchmark based on multiple postoperative endpoints that represent the ideal "textbook" hospitalization. We sought to define TO for liver transplantation (LT) using a cohort from a high procedural volume center.

Methods: Patients who underwent LT at our institution between 2014 and 2017 were eligible for the study. The definition of TO was determined by clinician consensus at our institution to include freedom from: mortality within 90 days, primary allograft non-function, early allograft dysfunction (EAD), rejection within 30 days, readmission with 30 days, readmission to the ICU during index hospitalization, hospital length of stay > 75th percentile of all liver transplant patients, red blood cell (RBC) transfusion requirement greater than the 75th percentile for all liver transplant patients, Clavien-Dindo Grade III complication (re-intervention), and major intraoperative complication.

Results: Two hundred and thirty-one liver transplants with complete data were performed within the study period. Of those, 71 (31%) achieved a TO. Overall, the most likely event to lead to failure to achieve TO was readmission within 30 days (n = 57, 37%) or reoperation (n = 49, 32%). Overall and rejection-free survival did not differ significantly between the 2 groups. Interestingly, patients who achieved TO incurred approximately $60,000 less in total charges than those who did not. When we limit this to charges specifically attributable to the transplant episode, the difference was approximately $50,000 and remained significantly less for those that achieved TO.

Conclusions: Here, we present the first definition of TO in LT. Though not associated with long-term outcomes, TO in LT is associated with a significantly lower charges and costs of the initial hospitalization. A multi-institutional study to validate this definition of TO is warranted.
