Abstract
INTRODUCTION: "Healthcare contact days" is a patient-centered quantitative proxy for time toxicity, which can be informative for liver transplant (LT) decision-making. We aimed to (i) quantify contact days in patients with cirrhosis pre-LT and post-LT and (ii) identify clinical and demographic features associated with contact days. METHODS: Using a national health system database, we calculated healthcare contact days (inpatient, outpatient hospital [e.g. observation], ambulatory, emergency, mental health, other) for patients with cirrhosis before and after LT. RESULTS: Between 2008 and 2023, 2,708 patients underwent LT (median age 59 years [interquartile range 52-65], 66% male, 68% non-Hispanic White). Total mean contact days were 76.0 (SD, 58.6) 1 year pre-LT, increasing to 92.3 (SD, 63.2) 1 year post-LT, then decreasing to 39.7 (SD, 43.3) and 30.9 (SD, 35.6) 2 years and 3 years post-LT, respectively. The mean inpatient contact days were 33.6 (SD, 47.5) 1 year pre-LT, increasing to 49.6 (SD, 59.1) 1 year post-LT, then decreasing to 11.9 (SD, 32.0) and 6.7 (SD, 19.8) 2 years and 3 years post-LT, respectively. In multivariable analysis, pre-LT contact days were not associated with post-LT days (incidence rate ratio [IRR] 1.00 [1.00-1.00]). Post-LT, female gender (IRR 1.09 [1.03-1.15]), Black race (IRR 1.11 [1.00-1.23]), and pre-LT dialysis (IRR 1.21 [1.10-1.34]) were associated with increased total contact days. DISCUSSION: Healthcare contact days provide interpretable prognostic information to inform expectations regarding LT for cirrhosis and can be useful for patients, providers, and policymakers alike.
