Data availability statement

We analyzed the NIS database from 2008 to 2018, available online at http://www.hcup-us.ahrq.gov. The NIS is a large, multi-ethnic, publicly available all-payer inpatient care database in the US containing data on more than seven million hospital stays yearly. Its large sample size is ideal for developing national and regional estimates and enables analyses of rare conditions, uncommon treatments, and special populations.
