Longitudinal research files

These files are intended to make our database easier to use for researchers conducting longitudinal studies. They include data for multiple years for each measure, most going back at least as far as 2008, allowing researchers to access several years' worth of Dartmouth Atlas rate data. In addition to adjusted rates, the files contain crude rates, numerators, denominators, 95% confidence limits, and standard errors. They are available in zipped-compressed STATA (.dta), SAS (.sas7bdat), and CSV (.csv) formats to allow investigators to use the software of their choice to run analyses. Data are available for states, hospital referral regions, hospital service areas, counties, and individual hospitals. The older Microsoft Access (.mdb) files have been moved here.
