Factors Associated With Readmission and Mortality of Hospitalized Individuals With Intellectual and Developmental Disabilities in Four U.S. States.

This study examined demographics, social determinants of health, comorbidities, and outcomes (mortality and readmissions) of hospitalized patients with intellectual and developmental disabilities (IDD). The sample included 39,256 hospital admissions for adult inpatients with IDD from four states. Logistic regression analyzed factors influencing 30-day readmission and in-hospital mortality. Results showed a 17.5% 30-day readmission rate. Black race, Medicare/Medicaid insurance, and admission from another facility were associated with higher odds of readmission. Age, Medicare insurance, and admission from emergency rooms, another hospital, or facility were associated with higher odds of in-hospital mortality. The study highlights the complex interplay of factors affecting outcomes for patients with IDD, emphasizing the need for targeted interventions and improved hospital care to address health disparities in this population.
