Identifying and understanding risk factors for 30-day readmission following hip fracture surgery is essential for improving patient management and optimizing healthcare resource utilization. Methods: A systematic literature search was conducted using PubMed, EMBASE, and the Cochrane Library databases up to 30 December 2024. Studies investigating potential risk factors for 30-day readmission following hip fracture surgery were included. The risk factors were meta-analytically pooled, and odds ratios (ORs) were calculated using a random-effects model. Results: Twelve studies comprising 128,053 patients were included. Pooled analyses revealed significant associations between higher readmission rates and factors such as male sex (OR = 1.45; 95% CI, 1.27\u20131.65), hip arthroplasty surgery (OR = 1.36; 95% CI, 1.03\u20131.80), advanced age (OR, 1.22; 95% CI 1.00\u20131.49), high American Society of Anesthesiologists (ASA) Physical Status Classification System class (OR, 2.22; 95% CI, 1.28\u20133.85), and high Charlson comorbidity index (OR, 1.67; 95% CI, 1.36\u20132.05). Additionally, the most frequently reported comorbidities associated with higher readmission risks were diabetes mellitus and congestive heart failure, with ORs of 1.63 and 1.57, respectively. Conclusions: Male sex, advanced age, higher ASA scores, and greater preoperative comorbidity burdens significantly increase the risk of 30-day readmission following hip fracture surgery. Effective risk stratification and targeted perioperative management strategies addressing these identified factors may reduce early readmission rates and enhance postoperative patient outcomes.<\/jats:p>","DOI":"10.3390\/jcm14082779","type":"journal-article","created":{"date-parts":[[2025,4,17]],"date-time":"2025-04-17T20:05:56Z","timestamp":1744920356000},"page":"2779","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Risk Factors for Readmission Within 30 Days After Discharge Following Hip Fracture Surgery: A Systematic Review and Meta-Analysis"],"prefix":"10.3390","volume":"14","author":[{"given":"Kyung-Joo","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, National Police Hospital, Seoul 05715, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji Wan","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul 05505, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9233-5358","authenticated-orcid":false,"given":"Chul-Ho","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul 05505, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1064","DOI":"10.1002\/jbmr.4821","article-title":"Global Epidemiology of Hip Fractures: Secular Trends in Incidence Rate, Post-Fracture Treatment, and All-Cause Mortality","volume":"38","author":"Sing","year":"2023","journal-title":"J.
