Impact of the FLS model on patients with major fracture in Gran Canaria: 2018-2022 experience

Abstract

We analyzed 5396 patients with fragility fracture, their inclusion by the FLS, and prescription of treatment. Thirty-four percent of potential cases were attended by the FLS, and at the healthcare level, the impact of FLS model resulted in an increase of treated patients from 20% in standard care to 41%.Introduction Patients with fragility fractures are at high risk of new fractures, with a negative impact on their quality of life, as well as higher mortality and costs for the health system, especially for hip fractures. Less than 20% of patients receive treatment (lifestyle advice, calcium, vitamin D, and bisphosphonate) after a fracture. The fracture liaison service (FLS) is the most effective model for secondary prevention.Objectives To analyze the incidence of fragility fractures in the area of Gran Canaria North and the impact of the FLS unit on the prevention of new fractures.Methods Patients > 50 years were attended at the emergency department for fractures of the proximal femur, proximal humerus, distal forearm, pelvis, or vertebra during the period 2018-2022 were included. A file was constructed containing demographic data, type of fracture, inclusion in the FLS, and the initiation of treatment to prevent new fractures. A sample of patients not treated at the FLS was selected for estimating the prophylaxis of fractures under standard care management.Results A total of 5396 patients were included, 74.2% women, with a mean age of 74 years. After excluding 558 traumatic fractures (10.3%), 318 (5.9%) deaths, and 167 (3.1%) cases due to a lack of criteria, the sample of potential patients who were candidates for FLS was 4353. This represented 80.6% of the initial sample, of which 1497 patients (34.4%) were attended at the unit. Factors independently associated with referral to the FLS were younger age (OR 0.97; 95% CI 0.97-0.98), female sex (OR 2.24; 95% CI 1.91-2.61), and humerus fracture (OR 1.34; 95% CI 1.16-1.55). Treatment to prevent fractures was verified in 1189 patients (79.4%) in the FLS group and in 585 (20.4%) of those with fragility fractures who were not included. At the healthcare level, the services provided by the FLS resulted in an increase in treated patients from 20% in standard care to 41% with the FLS model.Conclusions In terms of treatment initiation to new fracture prevention at the healthcare level, the FLS achieved a twofold increase. The high incidence of fractures and the progressive aging of the population underline the effectiveness of the FLS secondary prevention model.
