The objective of this study was to assess the inpatient care burden among individuals with autism using the 2007 Health Care Utilization Project Nationwide Inpatient Sample [HCUP-NIS]). There were ~26,000 hospitalizations among individuals with autism in 2007, with an overall rate of 65.6/100,000 admissions. Rates of hospitalizations were the highest among individuals with autism aged 10–20 years, males, having household income >$63,000, and with private insurance, respectively. In terms of hospital characteristics, rates were the highest in hospitals in large urban areas, located in the Northeast region, and with teaching status, respectively. Individuals with autism had significantly higher LOS (6.5 vs. 4.2; p < 0.0001) and total charges ($24,862 vs. $23,225; p < 0.0001) as compared to those without autism.
