It is an important and modifiable risk factor for surgical patients. For high-blood-loss surgery, preoperative anemia is defined as hemoglobin &amp;lt;13 g\/dL for both male and female patients. Preoperative anemia is common, ranging from 25% to 40% in large observational studies. The most common treatable cause of preoperative anemia is iron-deficiency anemia; the initial laboratory tests should focus on making this diagnosis. Management of iron-deficiency anemia includes iron supplementation with IV iron therapy when oral iron is ineffective or not tolerated, there is severe anemia, and there is insufficient time to surgery (&amp;lt;4 weeks). In other situations, erythropoiesis-stimulating agents may be considered, particularly for those patients with multiple alloantibodies or religious objections to transfusion. To facilitate the diagnosis and management of preoperative anemia, establishment of preoperative anemia-screening clinics is essential. The goals of management of preoperative anemia are to treat anemia, reduce the need for transfusion, and improve patient outcomes.<\/jats:p>","DOI":"10.1182\/hematology.2019000061","type":"journal-article","created":{"date-parts":[[2019,12,6]],"date-time":"2019-12-06T15:15:59Z","timestamp":1575645359000},"page":"570-576","update-policy":"https:\/\/doi.org\/10.1182\/blood.2019cm0000","source":"Crossref","is-referenced-by-count":59,"title":["Preoperative anemia-screening clinics"],"prefix":"10.1182","volume":"2019","author":[{"given":"Yulia","family":"Lin","sequence":"first","affiliation":[{"name":"Transfusion Medicine and Tissue Bank, Department of Laboratory Medicine and Pathobiology, Sunnybrook Health Sciences Centre, Toronto, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"234","reference":[{"issue":"11","key":"2019120610112161100_B1","doi-asserted-by":"crossref","first-page":"1314","DOI":"10.1002\/bjs.9861","article-title":"Meta-analysis of the association between preoperative anaemia and mortality after surgery","volume":"102","author":"Fowler","year":"2015","journal-title":"Br J Surg"},{"issue":"10","key":"2019120610112161100_B2","doi-asserted-by":"crossref","first-page":"983","DOI":"10.1001\/jama.2019.0554","article-title":"Patient blood management: recommendations from the 2018 Frankfurt Consensus Conference","volume":"321","author":"Mueller","year":"2019","journal-title":"JAMA"},{"issue":"9800","key":"2019120610112161100_B3","doi-asserted-by":"crossref","first-page":"1396","DOI":"10.1016\/S0140-6736(11)61381-0","article-title":"Preoperative anaemia and postoperative outcomes in non-cardiac surgery: a retrospective cohort study","volume":"378","author":"Musallam","year":"2011","journal-title":"Lancet"},{"issue":"3","key":"2019120610112161100_B4","doi-asserted-by":"crossref","first-page":"416","DOI":"10.1093\/bja\/aeu098","article-title":"Preoperative anaemia is associated with poor clinical outcome in non-cardiac surgery patients","volume":"113","author":"Baron","year":"2014","journal-title":"Br J Anaesth"},{"issue":"1","key":"2019120610112161100_B5","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1016\/j.transci.2013.12.010","article-title":"The ONTraC Ontario program in blood conservation","volume":"50","author":"Freedman","year":"2014","journal-title":"Transfus Apheresis Sci"},{"issue":"6","key":"2019120610112161100_B6","doi-asserted-by":"crossref","first-page":"627","DOI":"10.1111\/anae.13423","article-title":"The incidence and importance of anaemia in patients undergoing cardiac surgery in the UK -
