The aim of this study was to investigate long\u2010term survival of ICU patients in Iceland and assess changes over a 15\u2010year period.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Data were collected on age, gender, admission cause, length of stay, comorbidities, mechanical ventilation and survival of patients 18\u00a0years and older admitted to the ICUs in Landspitali during 2002\u20102016. Long\u2010term survival of patients surviving more than 30\u00a0days from admission was estimated and its predictors assessed with Cox regression analysis. Long\u2010term survival was compared to the survival of an age\u2010 and gender\u2010matched reference group from the general population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of 15\u00a0832 ICU admissions, 55% was medical, 38% was surgical and 7% was due to trauma. The 5\u2010year survival of medical, surgical and trauma patients was 66%, 76% and 92% respectively. Significant survival differences were found between admission subgroups. Higher age and comorbidity burden was related to decreased survival in all patient groups. After correcting for age, gender, comorbidities, length of ICU stay and mechanical ventilation, patient survival improved during the study period only for patients admitted for infections. There was a high variability in the estimated time point where the ICU admission had no residual effect on survival.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Long\u2010term survival of ICU patients is substantially decreased compared to the general population, but varies based on admission causes. Improved long\u2010term survival of patients admitted with infections could be explained by earlier detection and improved treatment of septic shock.<\/jats:p><\/jats:sec><\/jats:sec>","DOI":"10.1111\/aas.13475","type":"journal-article","created":{"date-parts":[[2019,9,17]],"date-time":"2019-09-17T04:28:06Z","timestamp":1568694486000},"page":"75-84","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Long\u2010term survival after intensive care: A retrospective cohort study"],"prefix":"10.1111","volume":"64","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5206-3615","authenticated-orcid":false,"given":"Eyrun A.","family":"Kristinsdottir","sequence":"first","affiliation":[{"name":"Division of Anaesthesia and Intensive Care Perioperative Services at Landspitali the National University Hospital of Iceland Reykjavik Iceland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thorir E.","family":"Long","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine at Landspitali the National University Hospital of Iceland Reykjavik Iceland"},{"name":"Faculty of Medicine University of Iceland Reykjavik Iceland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kristinn","family":"Sigvaldason","sequence":"additional","affiliation":[{"name":"Division of Anaesthesia and Intensive Care Perioperative Services at Landspitali the National University Hospital of Iceland Reykjavik Iceland"},{"name":"Faculty of Medicine University of Iceland Reykjavik Iceland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0726-4378","authenticated-orcid":false,"given":"Sigurbergur","family":"Karason","sequence":"additional","affiliation":[{"name":"Division of Anaesthesia and Intensive Care Perioperative Services at Landspitali the National University Hospital of Iceland Reykjavik Iceland"},{"name":"Faculty of Medicine University of Iceland Reykjavik Iceland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4171-9153","authenticated-orcid":false,"given":"Gisli H.","family":"Sigurdsson","sequence":"additional","affiliation":[{"name":"Division of Anaesthesia and Intensive Care Perioperative Services at Landspitali the National University Hospital of Iceland Reykjavik Iceland"},{"name":"Faculty of Medicine University of Iceland Reykjavik Iceland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7054-0844","authenticated-orcid":false,"given":"Martin I.","family":"Sigurdsson","sequence":"additional","affiliation":[{"name":"Division of Anaesthesia and Intensive Care Perioperative Services at Landspitali the National University Hospital of Iceland Reykjavik Iceland"},{"name":"Faculty of Medicine University of Iceland Reykjavik Iceland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,10,14]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00134-014-3348-y"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/CCM.0b013e31827ca4e1"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003246-199612000-00006"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s001340100960"},{"key":"e_1_2_8_6_1","first-page":"185","article-title":"Long\u2010term cognitive impairment after critical illness","volume":"370","author":"Pandharipande PP","year":"2014","journal-title":"N Engl J Med"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1011802"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13054-016-1248-y"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1186\/cc8848"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/CCM.0b013e3181f3dec5"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrc.2014.09.009"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00134-005-2744-8"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1097\/MLR.0b013e31819432e5"},{"key":"e_1_2_8_14_1","unstructured":"Statistics Iceland Reykjavik Iceland.
