Abstract
The New York City (NYC) Department of Health and Mental Hygiene (DOHMH) routinely collects daily emergency department (ED) data from 49 of NYC‰Ûªs 52 EDs. Very little information regarding ED-specific coding practices, procedures or health information systems was available to the DOHMH. With the goal of gaining more inforamtion about ED-specific coding practices, members of the DOHMH interviewed ED personnel at all 49 EDs. The information from these surveys is to be used to improve the DOHMH‰Ûªs ability to categorize ED visits into syndrome groupings.
