Yli-Kyyny TT, et al. - Researchers sought for the risk factors associated with the occurrence of early readmission due to surgical complications after hip fracture surgery. They studied a nationwide database with 68,800 hip fracture patients treated between 1999 and 2011 to determine the association of readmissions with co-morbidities, fracture types, different hospital types and treatment methods using the Cox proportional hazards model. Findings revealed a 4.6% risk for a readmission due to a surgical complication after hip fracture surgery. Higher readmission rates were observed among patients with: heavy alcoholism (HR 1.38; 95% CI: 1.23–1.53); Parkinson’s disease (PD; HR 1.22; 95% CI: 1.05–1.42); pre-existing osteoarthritis (HR 2.02; 95% CI: 1.83–2.23); rheumatic disease (HR 1.44; 95% CI: 1.27–1.65); as well as those with a fracture of the femur neck, depression, presence of a psychotic disorder, an operative delay of at least three days, or previous treatment with total hip arthroplasty.
