[Translated article] Analysis of the demand of care from Primary Care to Traumatology: Proposals for the improvement of the continuous care.

OBJECTIVE: To analyse referrals from Primary Care consultation to Orthopaedic Surgery reference department. As a secondary objective, to establish 2 referral scenarios in order to determine the impact of variability on referral. MATERIAL AND METHODS: Cross-sectional observational study, analyzing referrals from Primary Care to Orthopaedic Surgery during the first half of the years 2018, 2019, and 2021. The number of referrals issued by each doctor and each Primary Care Healthcare Center was examined, according to the classification of the different Basic Healthcare Zones. RESULTS: There is great variability in the number of referrals, both according to the type of Basic Healthcare Zone and by each Primary Care facultative. The referral ratios behaved uniformly over time (p<0.001). Due to a large number of referrals, 2 scenarios have been constructed: In the first scenario, the referral ratio would be in the middle of the referral rate spectrum. In the second scenario, the lowest referral ratios recorded have been taken as a reference. The reduction of variability in the 2 scenarios assumed provides a significant reduction in the demand for care. CONCLUSION: Reducing variability would have a beneficial effect on the capacity of the Orthopaedic Surgery service to provide care.

Effect of hip hemiarthroplasty dislocation on mortality after hip fracture surgery. / [Artículo traducido] Efecto de la luxación de la prótesis parcial de cadera en la mortalidad tras la cirugía de fractura de cadera.

INTRODUCTION: Hip arthroplasty is the treatment of choice for displaced femoral neck fractures among the older population. The hip prosthesis dislocation is one of the most pointed potential complications after hip arthroplasty, but there is a lack of updated information on the effect of dislocation on the survival of older hip fracture patients so treated by hip hemiarthroplasty. We aim to evaluate the standalone effect of hip prosthesis dislocation after hip fracture hemiarthroplasty on patients' survival outcomes. MATERIALS AND METHODS: We conducted a retrospective multicenter study, including 6631 femoral neck fracture patients over 65 surgically treated by hemiarthroplasty. We made follow-up cut-offs 30-days, 6 weeks, 90-days, and one year after hospital discharge determining hip dislocation rate and patients' survival. RESULTS: The women population represented 78.7%, and the mean age of the population was 85.2 ± 6.7 years. Hip prosthesis dislocation incidence was 1.9% in the first 90-days after discharge, representing 91.54% of primary dislocations yearly noted. We reported statistically significant increased mortality rates of patients presenting at least one hip prosthesis dislocation event (from 16.0% to 24.6% at 90-day after discharge, and 29.5% to 44.7% at one year), and also significantly decreasing patient survival function at 90-day (P = .016) and one-year follow-up (P < .001). The recurrent dislocation events (26.15%) showed even higher mortality rates (up to 60.6%, p < .001). The multivariate Cox regression model determined that prosthesis dislocation was the only significant variable (P = .035) affecting patient survival, increasing the risk of dying before one year of follow-up by 2.7 times. DISCUSSION: Our study stands for the standalone hip prosthesis dislocation entailing a higher risk of death after hip fracture hemiarthroplasty in the older population.
