 METHODS AND ANALYSIS This is a multicenter, incomplete stepped-wedge cluster randomized controlled trial, where the intervention strategy is sequentially carried out in three groups of centers clusters with 5 centers each and in three equally spaced time periods epochs every 4 months. The study also includes an initial epoch during which none of the centers is exposed to the intervention, and a final epoch when all centers will have implemented the strategy . The intervention is applied at a cluster level unit of randomization and assessed at an individual level with cross-sectional model. 720 patients will be included, i.e. 60 patients in each cluster for every detection epoch.
