The initial 6 months will include 3 healthcare sectors: Lleida (168k inhabitants, 21 Primary Care Centers), Vic (49k inhabitants, 11 PCC), and AISBE (540k inhabitants, 19 PCC) following a Plan-Do-Study-Act (PDSA) methodology. The first PDSA cycle (January - March 2016) including a total of 3 PCC, one in each healthcare sector, has as main purpose to ensure full functionality of the setting. The FS program will be progressively deployed to all PCC in the 3 sectors in a second 3-months PDSA cycle that will be completed by mid-2016. FS testing will be prescribed by general practitioner following standard criteria and it will be carried out by primary care nurses. The deployment in the entire region (7.5M inhabitants and 369 Primary Care centers) will be completed within 2016.
