Factors affecting one-year mortality in patients over 65 years of age undergoing surgery for hip fracture.

Objectives: In this study, our objective was to investigate the factors that affect 1-year mortality in patients over 65 years of age who were hospitalized due to hip fracture.

Methods: This retrospective cohort study is based on data from our clinical archives collected between January 2013 and December 2021. All consecutive patients over 65 years of age with hip fractyres admitted to our hospital were considered for inclusion in the study.

Results: During the period from January 2013 to December 2021, 834 patients met the inclusion criteria. The one-year mortality rate was 33.5 % (279/834). The mean surgery time was 5.64 days in patients with 1-year mortality; and 4.50 days in patients who lived longer than one year (P = 0,001). The mean values of hemoglobin, creatinine, lymphocyte count, and albumin of patients in the one-year mortality group were 11.47 g/dL, 1.33 mg/dL, 1.10x103/μL and 3.42 g/L, respectively. The same values of those who survived for more than a year were 11.93 g/dL, 1.12 mg/dL, 1.35x103/μL and 3.68 g/L, respectively (P= 0.006, 0.002, 0.001 and 0,000, respectively).

Conclusions: We found that older patient age, delayed surgery, low albumin level, low total lymphocyte count, and high creatinine levels at hospital admission are associated with increased mortality after hip fracture. Comorbidities, number of comorbidities, transfusions, and ICU requirements were not associated with increased mortality, unlike the literature.
