This process yielded 53,495 patients. Demographic data as well as comorbidities, blood transfusions, postoperative 90 days medical complications, and mortality was investigated. Multivariate logistic regression analysis was performed to identify risk factors for one year mortality in patients undergoing surgical treatment for proximal hip fractures.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>The mortality rate was 37.2% in the first year. The mean Charlson comorbidity index(CCI) was 6.8 (range: 4\u201322). In the postoperative period, 68.6% of the patients received blood transfusions. Logistic regression analysis identified significant predictors of one-year mortality in surgical patients, including male gender, increased age, higher CCI scores, AKI, PE, pneumonia, electrolyte imbalance, gastrointestinal bleeding, blood transfusion, and increased mortality risks with hemiarthroplasty and internal fixation compared to total hip arthroplasty.
