Among low-weight patients, the lower body weight, preoperative anemia, and prolonged surgical duration were independently associated with increased bleeding risk. These findings highlight the importance of individualized risk assessment when considering a reduced fixed dose of enoxaparin for VTE prevention in low-weight patients undergoing surgery.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/10600280251349582","type":"journal-article","created":{"date-parts":[[2025,7,1]],"date-time":"2025-07-01T08:26:52Z","timestamp":1751358412000},"page":"248-257","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["The Rates of Bleeding and Venous Thromboembolism with Reduced-Dose Enoxaparin for Thromboprophylaxis in Low-Weight Surgical Patients: A Retrospective Cohort Study"],"prefix":"10.1177","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6979-0966","authenticated-orcid":false,"given":"Hakeam","family":"Hakeam","sequence":"first","affiliation":[{"name":"Pharmaceutical Care Division, King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia"},{"name":"College of Medicine, Alfaisal University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4685-2247","authenticated-orcid":false,"given":"Amjaad","family":"Alfahed","sequence":"additional","affiliation":[{"name":"Pharmacy Practice Department, College of Pharmacy, Princess Nourah bint Abdulrahman University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanin","family":"Aldalham","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, Epidemiology and Scientific Computing, King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gamal","family":"Mohamed","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, Epidemiology and Scientific Computing, King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,7]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2022.05.041"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.19.01461"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1378\/chest.11-2297"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1001\/jamasurg.2018.0015"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.0007-1323.2001.01800.x"},{"issue":"8","key":"e_1_3_2_7_2","first-page":"1099","volume":"84","author":"Efficacy safety of enoxaparin versus unfractionated heparin for prevention of deep vein thrombosis in elective cancer surgery: a double-blind randomized multicentre trial with venographic assessment","year":"1997","unstructured":"Efficacy safety of enoxaparin versus unfractionated heparin for prevention of deep vein thrombosis in elective cancer surgery: a double-blind randomized multicentre trial with venographic assessment.
