Background: Since most hip fractures occur in fragile patients, an important step forward in the treatment may be a co-managed, multidisciplinary treatment approach with orthopaedic surgeons and geriatricians. This multidisciplinary care model (MCM) is implemented in some Tuscan hospitals, while in hospitals with the usual care model (UCM) medical consultation is required only as deemed necessary by the admitting surgeon. The primary aim of this study was to assess the effect of the MCM on 30-day mortality, compared with the UCM.
Methods: A retrospective study was conducted on patients with main diagnosis of hip fracture, as reported in the hospital admission discharge reports, aged 65 years and older, who underwent surgery in Tuscan hospitals from 2010 to 2013. A multilevel logistic regression model was performed to assess the effect of the MCM vs the UCM. The Charlson Comorbidity Index (CCI) was used as a proxy for case mix complexity.
Results: 23,973 patients were included: 23% men and 77% women; the mean age was 83.5 years. The multilevel analysis showed that mortality was significantly higher in the UCM, after adjusting for gender, age, comorbidity and timing of surgery (OR=1.32; 95% CI 1.09-1.59; p=0.004). Surgical delay was not significantly associated with higher mortality rates.
Conclusions: A co-managed approach to hip fracture, with orthopaedic surgeons and geriatricians, offers a multidisciplinary pathway for the elderly and leads to a reduction in mortality after hip fracture surgery.
