There is increasing interest in the federal government in providing care coordination for homeless patients, which will require a systematic way of identifying these individuals.<\/jats:p>\n               <jats:p>Objective We analyzed address data from Healthix, a New York City\u2013based health information exchange, to identify patterns that could indicate homelessness.<\/jats:p>\n               <jats:p>Methods Patients were categorized as likely to be homeless if they registered with the address of a hospital, homeless shelter, place of worship, or an address containing a keyword synonymous with \u201chomelessness.\u201d<\/jats:p>\n               <jats:p>Results We identified 78\u2009460 out of 7\u2009854\u2009927 Healthix patients (1%) as likely to have been homeless over the study period of September 30, 2008 to July 19, 2013. We found that registration practices for these patients varied widely across sites.<\/jats:p>\n               <jats:p>Conclusions The use of health information exchange data enabled us to identify a large number of patients likely to be homeless and to observe the wide variation in registration practices for homeless patients within and across sites. Consideration of these results may suggest a way to improve the quality of record matching for homeless patients. Validation of these results is necessary to confirm the homeless status of identified individuals. Ultimately, creating a standardized and structured field to record a patient\u2019s housing status may be a preferable approach.<\/jats:p>","DOI":"10.1093\/jamia\/ocu005","type":"journal-article","created":{"date-parts":[[2015,2,11]],"date-time":"2015-02-11T04:04:50Z","timestamp":1423627490000},"page":"682-687","source":"Crossref","is-referenced-by-count":26,"title":["Identifying homelessness using health information exchange data"],"prefix":"10.1093","volume":"22","author":[{"given":"John","family":"Zech","sequence":"first","affiliation":[{"name":"Department of Emergency Medicine, Icahn School of Medicine at Mount Sinai, New York, NY, 10029, USA,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregg","family":"Husk","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Mount Sinai Beth Israel, New York, NY, 10003, USA,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Moore","sequence":"additional","affiliation":[{"name":"Healthix, Inc., New York, NY, 10013, USA,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gilad J","family":"Kuperman","sequence":"additional","affiliation":[{"name":"New York-Presbyterian Hospital, New York, NY, 10032, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jason S","family":"Shapiro","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Icahn School of Medicine at Mount Sinai, New York, NY, 10029, USA,"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2015,2,10]]},"reference":[{"key":"2020110612593240400_ocu005-B1","doi-asserted-by":"crossref","first-page":"279","DOI":"10.3122\/jabfm.2013.03.120239","article-title":"A primary care-public health partnership addressing homelessness, serious mental illness, and health disparities","volume":"26","author":"Weinstein","year":"2013","journal-title":"J Am Board Fam Med"},{"key":"2020110612593240400_ocu005-B2","article-title":"Premature mortality in homeless populations: a review of the literature","author":"O\u2019Connell"},{"key":"2020110612593240400_ocu005-B3","doi-asserted-by":"crossref","first-page":"405","DOI":"10.7326\/0003-4819-104-3-405","article-title":"Homeless persons and health care","volume":"104","author":"Brickner","year":"1986","journal-title":"Ann Intern Med"},{"key":"2020110612593240400_ocu005-B4","doi-asserted-by":"crossref","first-page":"18","DOI":"10.1111\/j.1365-2524.2008.00793.x","article-title":"Survey findings on characteristics and health status of clients treated by the federally funded (US) Health Care for the Homeless Programs","volume":"17","author":"Zlotnick","year":"2009","journal-title":"Health Soc Care Commun"},{"key":"2020110612593240400_ocu005-B5","doi-asserted-by":"crossref","first-page":"2030","DOI":"10.1001\/archinte.1990.00390210032009","article-title":"Human immunodeficiency virus infection among homeless men in a New York City shelter association with mycobacterium tuberculosis infection","volume":"150","author":"Torres","year":"1990","journal-title":"Arch Intern Med"},{"key":"2020110612593240400_ocu005-B6","doi-asserted-by":"crossref","first-page":"1","DOI":"10.2105\/AJPH.2013.301586","article-title":"Health care for the homeless: what we have learned in the past 30 years and what\u2019s next","volume":"103","author":"Zlotnick","year":"2013","journal-title":"Am J Public Health"},{"key":"2020110612593240400_ocu005-B7","doi-asserted-by":"crossref","first-page":"446","DOI":"10.1111\/j.1365-2524.2007.00703.x","article-title":"Where do people go when they first become homeless?
