On priority setting in preventive care resources

Using an expected utility approach, we show that within a population that differs with respect to the probability of developing a disease, the allocation of preventive care resources should be prioritized based on the efficiency of prevention and not on whether individuals are at high or low risk of developing the disease. Should the efficiency of prevention be the same within the population, we show that the gravity of the disease, the presence of co-morbidities and the existence of uncertainty on health status can alternatively be considered so as to prioritize among preventive care resources.
