Utilizing a study of the costs of providing essential services in rural areas in Bangladesh projections of the cost of expanding services to the entire rural population are derived. These estimates are based on the current system of primary care, the demographic structure of the population and normatives for desired utilization. Scenarios make use of known demographic characteristics of average rural areas together with information on disease prevalence.

The estimates highlight a number of difficulties involved in deriving costs and in comparing the cost-effectiveness of service provision. The integrated nature of much primary care, both in terms of the technical exploitation of joint costs and clinical diagnostic and treatment protocols, means that treating services in isolation is likely to lead to inexact estimates of service cost. The context of any costs derived is required in order to make comparisons
