Sex Differences in Hip Fracture Surgery: Preoperative Risk Factors for Delirium and Postoperative Outcomes
Oh ES, Sieber FE, Leoutsakos JM, Inouye SK, Lee HB.. Journal of the American Geriatrics Society, 2016-07-07
Topic: Risk, prevention and care in population studies
Objectives To describe the differences observed in risk factors for delirium and outcomes between men and women undergoing hip fracture repair surgery. Design Prospective cohort study. Setting Academic medical center. Participants Individuals with acute hip fracture admitted to an academic medical center (N = 431). Measurements Information on preoperative demographic characteristics, medical history, laboratory results, and postoperative outcomes was obtained according to history and chart review. Delirium was assessed using the Confusion Assessment Method. Results The overall incidence of postoperative delirium was 34%, with men more likely to experience postoperative delirium (44.8%) than women (30.2%) (P = .004). Male sex was associated with postoperative delirium in individuals with hip fracture, even after adjusting for other preoperative risk factors. Other significant preoperative risk factors included age, dementia, Parkinson's disease, and American Society of Anesthesiologists classification. Men were also more likely to experience other postoperative complications and have longer hospital length of stay. Conclusion Men are at higher risk of postoperative delirium after hip fracture repair than women and have more postoperative surgical complications. Their higher risk of postoperative delirium may be due to their underlying preoperative disease severity.

How this study scored 64/100
Published in a peer-reviewed journal, and it is a cohort study following people over time. Scored zero for randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 37 of the 58 points we could judge it on, which is 64 out of 100.
