The Outcome of Surgically Treated Proximal Femur Fractures Managed by Ortho-anesthetic Geriatric Care Pathway: A Prospective Observational Study with 2-Year Follow-Up

BackgroundEvaluation of the ortho-anesthetic geriatric care pathway for patients with proximal femur fracture in a tertiary care referral center was done by reporting the peri-operative morbidity and mortality. Clinical and demographic predictors of mortality were also identified in this cohort.Material and MethodsThis prospective observational study was conducted between August 2017 and November 2018. Demographic, anesthetic and surgical characteristics were recorded. Telephonic post-discharge follow-up was done for a period of 2 years. Factors predicting mortality were estimated using multivariate logistic regression.ResultsThe cohort was characterized by frailty, high ASA physical status, NYHA class and Charlson co-morbidity index. The delay in presentation to hospital and subsequent surgical fixation was 7 (1-8) and 8 (5-13) days, respectively. The 30, 60, 90-day, 1-year and 2-year mortality was 13.6%, 21.8%, 25.45%, 36.5% and 44%, respectively. Intra-operative blood transfusion was a predictor of 30-day mortality (OR 9.2, 95% CI 1.02-83.17; p = 0.048). Pre-operative respiratory dysfunction predicted 60-day (OR 11.245, 95% CI 1.38-91.58; p = 0.024) and 90-day (OR 11.654, 95% CI 1.91-71.1; p = 0.008) mortality. Post-operative morbidity was reported in 31 (28.1%) patients; incidence of pneumonia (n = 9), sepsis (n = 8), MI (n = 6), PTE (n = 5) and ARF (n = 3) were 8.18%, 7.27%, 5.45%, 4.54% and 2.72%, respectively.ConclusionExisting pathway facilitated surgical fixation with median delay of 8 days which should be shortened to 48 h. High mortality in our cohort needs to be decreased by preventing admission delays and aggressively managing co-morbidities. Acceptable benchmark goals for pre-operative optimization of lung disease and decrease in intra-operative blood transfusion need to be incorporated in existing care pathway.
