Radiation proctitis: predictors of mortality and inpatient outcomes in the United States

Abstract Background: We aimed to evaluate the characteristics of hospitalizations for radiation proctitis (RP). Methods: The National Inpatient Sample (NIS) was analyzed to identify RP hospitalizations for 2016 and 2017. Outcomes included mortality, predictors of mortality, mean length of stay (LOS), mean total hospital cost (THC), and numerous system-based complications. Results: We identified 16,810 adult hospitalizations for RP. On admission, an initial diagnosis of RP was established for only 27.54% of these patients. The mean age was 72.3±0.5 years and
