[Sustainability in chronic disease prevention: lessons from the Salud al Paso program in Ecuador].

This study analyzes the conditions and possibilities of sustainability of the "Salud al Paso" program of the Metropolitan Health Secretariat of the Municipality of Quito, Ecuador, as an example for similar initiatives, in the context of the changes made by the new administration in May 2019. The analysis of this implementation, focused on the prevention of noncommunicable diseases, was based on the program's user database, the information gathered on the perspectives of operational personnel, knowledge of the program, and the opinion of local leaders and opinion leaders of the Quito Metropolitan District, as well as official information. Based on this data, the study identified factors that could have facilitated or hindered its sustainability and documented the rationale to suspend the free demand activities included in the program and limit the activities to the care of populations under municipal responsibility (day-care centers, schools and colleges, markets, elderly care programs and employees) and patients with identified cardiometabolic risk.
