Disparities and Outcomes of Physical Restraint Use in Hepatic Encephalopathy: A National Inpatient Assessment

Physical restraints may be utilized in patients with hepatic encephalopathy with the intention to ensure patient safety. Determine if racial and socioeconomic disparities exist in restraint use for patients with hepatic encephalopathy and determine clinical efficacy of restraints in hepatic encephalopathy. We performed a cross-sectional retrospective study of hospitalizations for hepatic encephalopathy from 2016 to 2021 using the National Inpatient Sample. Patient race and income were assessed for associations with restraint use and restraints themselves were then assessed for associations with clinical outcomes including mortality. Separate analyses were performed for hospitalizations with and without invasive cares defined as the presence of ICD-10 codes for mechanical ventilation, gastric tube placement and/or central venous catheter placement. Restraint use was documented in 2.4% of 228,430 hospitalizations. In hospitalizations without defined invasive cares, restraint use was increased in Black patients compared to White patients (aOR = 1.57, 95% CI 1.24-1.98, p
