Predictors of and hospital-level variation in intensive care unit readmissions in Japan: a nationwide inpatient database study.

ABSTRACT:

Background

Intensive care unit (ICU) readmission is a widely recognized marker of patient outcomes and organizational performance. Early ICU readmission-commonly defined as a return to the ICU within 48 h or 2 full calendar days-has been posited as a quality indicator. However, its appropriateness as a quality indicator remains debatable, and evidence from Japan is limited.

Methods

We conducted a retrospective nationwide cohort study in Japan using data from the Diagnosis Procedure Combination database linked with the Hospital Bed Function Report from 2018 through 2023. Adults who were discharged alive after their initial ICU stay, with available Sequential Organ Failure Assessment (SOFA) scores at ICU admission and discharge were included. The primary outcome was early ICU
