More than one-quarter of inpatient stays in the United States involve at least one operating room (OR) procedure, with these stays being more than twice as costly as stays without OR procedures.
A Healthcare Cost and Utilization Project (HCUP) Statistical Brief presents statistics on OR procedures performed during inpatient stays using the 2018 National Inpatient Sample (NIS). In the brief, inpatient stays with and without OR procedures are compared in terms of patient characteristics, utilization characteristics, and outcomes. Additionally, the most common all-listed and most costly principal OR procedures are presented overall and by patient sex-age group.
In 2018, 9.6 million inpatient stays involved OR procedures, with a total of 14.4 million OR procedures. Stays involving OR procedures totaled $210.3 billion in aggregate costs. Appendectomy was found to be the most common operating room procedure among children in 2018, at a rate of 69.1 per 100,000 males and 48.1 per 100,000 females.
