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 1988 NIS data belong to NIS Release 1, which spans the years 1988-1992. When the NIS began in 1988, eight states were included. As of 2011, data from 46 states were included in the NIS. The 1988 dataset includes information on all inpatient stays from over 700 hospitals, totaling approximately 5.3 million records.
