Summary
The Nationwide Inpatient Sample (NIS) is a database of hospital inpatient stays. It was developed by the Healthcare Cost and Utilization Project (HCUP), and is meant to approximate a 20% sample of United States community hospitals. Variables include patient demographics, diagnosis and procedure codes, admission and discharge status, length of stay, expected payer, total charges, and hospital characteristics.
The 1998 NIS release includes data from 22 states. When the NIS began in 1988, eight states were included. As of 2011, data from 46 states were included in the NIS. The 1998 release includes information on all inpatient stays from close to 1,000 hospitals, totaling approximately 6.8 million records.
