We collected the following demographics: 1) patient age and sex; 2) visit details \u2013 number of ED visits, inpatient admissions, length of inpatient admissions, diagnosis, and primary location of pain; 3) current and past substance abuse, mental health and medical conditions. Charts were reviewed independently by two reviewers. ED visits were classified as either \u201cchronic pain\u201d or \u201cnot chronic pain\u201d related.<\/jats:p><\/jats:sec><jats:sec id=\"S1481803519004640_sec_a3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>We analyzed 4,646 visits for 247 patients, mean age was 47.2 years (standard deviation = 17.8), and 50.2% were female. This chart review study found 38% of high-frequency users presented with chronic pain to the ED and that women were overrepresented in this group (64.5%). All high-frequency users presented with co-morbidities and\/or mental health concerns. High-frequency users with chronic pain had more ED visits than those without and 52.7% were prescribed an opioid. Chronic abdominal pain was the primary concern for 54.8% of high-frequency users presenting with chronic pain.<\/jats:p><\/jats:sec><jats:sec id=\"S1481803519004640_sec_a4\" sec-type=\"conclusions\"><jats:title>Conclusions<\/jats:title><jats:p>Chronic pain, specifically chronic abdominal pain, is a significant driver of ED visits among patients who frequently use the ED. Interventions to support high-frequency users with chronic pain that take into account the complexity of patient's physical and mental health needs will likely achieve better clinical outcomes and reduce ED utilization.<\/jats:p><\/jats:sec>","DOI":"10.1017\/cem.2019.464","type":"journal-article","created":{"date-parts":[[2020,3,26]],"date-time":"2020-03-26T06:35:50Z","timestamp":1585204550000},"page":"350-358","source":"Crossref","is-referenced-by-count":17,"title":["Characteristics of frequent users of the emergency department with chronic pain"],"prefix":"10.1007","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4366-6713","authenticated-orcid":false,"given":"Yaadwinder","family":"Shergill","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danielle","family":"Rice","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catherine","family":"Smyth","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steve","family":"Tremblay","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer","family":"Nelli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebecca","family":"Small","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guy","family":"Hebert","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lesley","family":"Singer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joshua A.","family":"Rash","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patricia A.","family":"Poulin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2020,3,26]]},"reference":[{"key":"S1481803519004640_ref14","doi-asserted-by":"publisher","DOI":"10.1111\/j.1553-2712.2011.01086.x"},{"key":"S1481803519004640_ref22","doi-asserted-by":"publisher","DOI":"10.1155\/2016\/3092391"},{"key":"S1481803519004640_ref5","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0123660"},{"key":"S1481803519004640_ref35","doi-asserted-by":"publisher","DOI":"10.1016\/j.mcna.2015.08.007"},{"key":"S1481803519004640_ref40","unstructured":"Kelly, M There's a chronic pain crisis in Canada, and governments must address it - The Globe and Mail.
