This quality improvement project evaluated the leukocyte removal efficacy of three types of salvaged blood filters in autologous cell salvage.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Using a prospective observational cohort approach, we evaluated microaggregate, lipid-reducing, and leukocyte-reducing salvaged blood filters in adult patients undergoing surgery with autologous cell salvage. Filters were evaluated one after another, with samples of processed autologous blood collected prior to filtration and again after 30\u00a0mL had passed through each type of filter to allow for direct comparison of each filter\u2019s effects on WBC concentrations.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Salvaged blood samples were collected from 35 patients. Median pre-filtration WBC count was 9.8 [6.8-13.3] \u00d7 10\n 9<\/jats:sup>\n \/L, being reduced to 9.3 [6.6-12.6] \u00d7 10\n 9<\/jats:sup>\n \/L after microaggregate filtration (1.7 [\u22120.6-4.6]% removal), 0.8 [0.5-2.5] \u00d7 10\n 9<\/jats:sup>\n \/L after lipid filtration (89.7 [83.3-93.9]% removal), and 0.0 [0.0-0.0] \u00d7 10\n 9<\/jats:sup>\n \/L after leukocyte filtration (100 [100-100]% removal). The microaggregate filter achieved significantly less WBC reduction than both the leukocyte-reducing filter (\n p<\/jats:italic>\n < 0.0001) and lipid-reducing filter (\n p<\/jats:italic>\n < 0.0001). There was no significant difference observed between the leukocyte-reducing and lipid-reducing filters (\n p<\/jats:italic>\n = 0.3124).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Leukocyte- and lipid-reducing filters were effective at reducing WBCs from processed autologous blood by nearly 10-fold, while microaggregate filters were significantly less effective at removing leukocytes. Use of leukocyte- or lipid-reducing filters minimizes the number of activated WBCs reinfused to the patient during autologous cell salvage.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/02676591261485073","type":"journal-article","created":{"date-parts":[[2026,9,11]],"date-time":"2026-09-11T18:31:21Z","timestamp":1789151481000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparative efficacy of leukocyte removal by blood filters in autologous cell salvage"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-8857-2607","authenticated-orcid":false,"given":"Mark","family":"Alm","sequence":"first","affiliation":[{"name":"University Health Network"},{"name":"Medical University of South Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natasha","family":"Bush","sequence":"additional","affiliation":[{"name":"University Health Network"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alisa","family":"Maznytsya","sequence":"additional","affiliation":[{"name":"University Health Network"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mary","family":"Dooley","sequence":"additional","affiliation":[{"name":"Medical University of South Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Dell\u2019aiera","sequence":"additional","affiliation":[{"name":"Medical University of South Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stuart A.","family":"McCluskey","sequence":"additional","affiliation":[{"name":"University Health Network"},{"name":"University of Toronto"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Vallelonga","sequence":"additional","affiliation":[{"name":"University Health Network"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,9,11]]},"reference":[{"key":"e_1_3_6_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/anae.14331"},{"key":"e_1_3_6_3_2","doi-asserted-by":"publisher","DOI":"10.1051\/ject\/200335128"},{"key":"e_1_3_6_4_2","doi-asserted-by":"publisher","DOI":"10.1051\/ject\/1998303108"},{"key":"e_1_3_6_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12630-024-02893-0"},{"key":"e_1_3_6_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/ANA.0000000000000495"},{"key":"e_1_3_6_7_2","doi-asserted-by":"publisher","DOI":"10.1177\/026765910101600i109"},{"key":"e_1_3_6_8_2","volume-title":"Standards for perioperative autologous blood collection and administration","author":"Association for the Advancement of Blood & Biotherapies (AABB)","year":"2024","unstructured":"Association for the Advancement of Blood & Biotherapies (AABB).
