No more than 40% of Seguro Popular funds can go to human resources, no more than 30% can be spent on pharmaceuticals and a minimum of 20% can be spent on preventive activities. Yet beyond these figures, there is no clear resource allocation strategy at the state level, leaving states responsible for how they spend resources within these restrictions. The one exception is for public health interventions, where states make decisions in conjunction with the Ministry of Health to decide how they should allocate their spending on prevention activities. Similar shared decision-making approaches could possibly be employed for other types of spending, particularly for states with managerial capacity constraints. There remains a need for better accountability of how funds for health are used and for incentives and indicators to ensure that money is well spent.
