The eligible blood donor population was estimated from national census data taking the age limits, deferral criteria and deferral time\u2010period into account. As more than one disease\/condition may co\u2010exist, the estimate was adjusted to avoid over\u2010representation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of about 33 million Canadians aged 17 (18 in Qu\u00e9bec) to 65, 15\u00b71 million (45\u00b78%) are eligible to donate blood. This number increases to 15\u00b77 million when including people up to 71 years and to 17\u00b71 million in the absence of an upper age limit.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>As about 1\u00b72 million units are collected from 600\u2009000 donors annually, there are more than enough eligible people to meet the need. However, recruitment of donors is challenging and the absence of an upper age limit allows an additional 2 million people to donate. Other countries may wish to consider modification of the upper age criterion to address the effect of an aging population on the blood supply.<\/jats:p><\/jats:sec>","DOI":"10.1111\/j.1365-3148.2012.01184.x","type":"journal-article","created":{"date-parts":[[2012,9,24]],"date-time":"2012-09-24T03:55:13Z","timestamp":1348458913000},"page":"395-403","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["The impact of increasing the upper age limit of donation on the eligible blood donor population in Canada"],"prefix":"10.1111","volume":"22","author":[{"given":"W.","family":"Fan","sequence":"first","affiliation":[{"name":"Canadian Blood Services  Ottawa ON Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Q.\u2010L.","family":"Yi","sequence":"additional","affiliation":[{"name":"Canadian Blood Services  Ottawa ON Canada"},{"name":"Department of Epidemiology &amp; Community Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Xi","sequence":"additional","affiliation":[{"name":"Public Health Agency of Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Goldman","sequence":"additional","affiliation":[{"name":"Canadian Blood Services  Ottawa ON Canada"},{"name":"Department of Pathology &amp; Laboratory Medicine University of Ottawa  Ottawa ON Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Germain","sequence":"additional","affiliation":[{"name":"H\u00e9ma\u2010Qu\u00e9bec  Qu\u00e9bec QC Canada"},{"name":"Department of Social and Preventive Medicine University of Laval  Qu\u00e9bec QC Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.F.","family":"O'Brien","sequence":"additional","affiliation":[{"name":"Canadian Blood Services  Ottawa ON Canada"},{"name":"Department of Epidemiology &amp; Community Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,9,23]]},"reference":[{"key":"e_1_2_7_2_1","volume-title":"Technical Manual and Standards for Blood Banks and Transfusion Services","author":"AABB","year":"2011"},{"key":"e_1_2_7_3_1","unstructured":"Canadian Cancer Society\/National Cancer Institute of Canada(2008)Canadian Cancer Statistics 2008; Toronto Canada ISSN 0835\u20102976."},{"key":"e_1_2_7_4_1","unstructured":"Canadian Centre for Occupational Health(2007).Occupational Health and Safety Physical Hazard[WWW document].
