As part of the Center for Medicare and Medicaid Services Electronic Health Record Incentive Program, otherwise known as Meaningful Use, many New York City emergency departments participating in the city syndromic surveillance system have switched or are in the process of switching data format from text files to HL7 Messaging Standard Version 2.5.1. We evaluated data completeness, quality, and content from hospitals that are sending in both data formats in parallel. Although the sample size was small (n=4 hospitals), we found data completeness and quality improved as hospitals shifted to HL7 messaging. We will continue monitoring hospitals as they upgrade to this new format.
