It is widely recognized that health care is in a state of crisis. Increased public spending and a decline in support towards poor-resourced people dominate as standard explanations. In Denmark, a welfare state with universal health care, the crisis has led to an adjustment of the universal health care access. The political response has been to target health services to ‘those in need of special care’ through a more intense focus on prevention. The idea is to prevent illness instead of curing it. I study the impact of these new rules on the frontline level where home nurses, pedagogues and teachers interact with children and their families. A study shows that frontline workers think differently about whom to prevent from what, when and why. The degree of social distance as well as professional norms explain part of the variation in worries towards children and families, but the impact of collective orientation, tolerance and aversion remain unclear.
