Potential hip fracture early death predictors - a retrospective analysis from prospective trauma registry.

Objective: To explore the blood pressure, fracture anatomical site, and age as potential predictors of death within 3 months after proximal femoral fracture management.

Methods: The retrospective study was conducted from June 2015 and March 2020 at the Aga Khan University Hospital, Karachi and comprised orthopaedic trauma registry data of isolated proximal femur fracture patients managed between June 2015 and March 2020. Data of those who expired within 3 months of the management was pooled in group A, while data of those who survived >3 months post-treatment formed group B. Blood pressure at the time of hospital admission was considered normal at 90-120mmHg systolic and 60-80mmHg diastolic. Data was analysed using SPSS version 19.0.

Results: Of the 242 patients, 9(3.7%) were in group A; 5(55.5%) males and 4(44.4%) females with median age 78 years (interquartile range: 7 years). There were 233(96.3%) patients in group B; 123(52.7%) females and 110(47.2%) males with median age 70 years (interquartile range: 17 years). In 12 months post-treatment, 16(6.6%) patients expired; 9(56.25%) in group A, and 7(43.75%) in group B. Age >75 years and femoral neck fractures had a significant positive relationship with death within 3 months of surgical management (p<0.05).

Conclusion: Patients with femoral neck fracture and aged ≥75 years were found to be at the risk of death within 3 months post-management.
