In the Netherlands, female transfusion recipients under 45\u2009years currently receive RBCs matched for c, D, E and K antigens (D and cEK\u2010matching) to prevent alloantibody formation. We evaluated the cost versus utility of cEK\u2010matching strategies to optimize the prevention of HDFN.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods<\/jats:title>\n                    <jats:p>Four strategies for females under 45\u2009years of age were compared: current cEK\u2010matching, cK\u2010matching, K\u2010matching and no antigen matching. The model used recent Dutch data on alloimmunization incidence and incorporated lifetime costs and quality\u2010adjusted life years (QALYs). Sensitivity analyses were conducted to assess robustness across different assumptions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Compared to the current cEK\u2010matching strategy, cK\u2010matching reduced lifetime costs by \u20ac79,000 per yearly cohort of 177,248 pregnant women, with a minor QALY loss of 0.02. Matching for K only and no matching were both associated with higher costs and greater QALY losses. Across all plausible willingness\u2010to\u2010pay (WTP) thresholds, cK\u2010matching had the highest probability of being cost effective.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Transfusion matching for c and K, but not E, is the most cost\u2010effective strategy to prevent HDFN in the Dutch setting. Matching for E provides minimal health benefit at higher costs. These findings support revising current guidelines to cK\u2010matching, ensuring optimal prevention of HDFN while reducing healthcare expenditures.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/vox.70212","type":"journal-article","created":{"date-parts":[[2026,2,16]],"date-time":"2026-02-16T00:36:37Z","timestamp":1771202197000},"page":"861-868","source":"Crossref","is-referenced-by-count":1,"title":["Cost\u2010effectiveness of\n                    <scp>cEK<\/scp>\n                    \u2010preventive matched transfusion strategies for female transfusion recipients to prevent haemolytic disease of the foetus and newborn in the Dutch healthcare setting"],"prefix":"10.1111","volume":"121","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7300-6794","authenticated-orcid":false,"given":"Jessie S.","family":"Luken","sequence":"first","affiliation":[{"name":"Department of Immunohaematology Diagnostic Services Sanquin Diagnostic Services  Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy","family":"Bouman","sequence":"additional","affiliation":[{"name":"Department of Biomedical Data Sciences, Section Medical Decision Making Leiden University Medical Center (LUMC)  Leiden The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia C.","family":"Folman","sequence":"additional","affiliation":[{"name":"Department of Immunohaematology Diagnostic Services Sanquin Diagnostic Services  Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7044-0525","authenticated-orcid":false,"given":"Masja","family":"de Haas","sequence":"additional","affiliation":[{"name":"Department of Medical Affairs Sanquin Bloodbank  Amsterdam The Netherlands"},{"name":"Department of Haematology Leiden University Medical Center (LUMC)  Leiden The Netherlands"},{"name":"Sanquin Research and Landsteiner Laboratory Amsterdam UMC  Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elske","family":"van den Akker\u2010van Marle","sequence":"additional","affiliation":[{"name":"Department of Biomedical Data Sciences, Section Medical Decision Making Leiden University Medical Center (LUMC)  Leiden The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,2,15]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/vox.12265"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/bjh.15962"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/pd.5355"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2011.09.024"},{"key":"e_1_2_9_6_1","unstructured":"Resources Library.The International Society of Blood Transfusion (ISBT).
