Budgeting in health care systems.

During the last decade there has been a recognition that all health care systems, public and private, are characterised by perverse incentives (especially moral hazard and third party pays) which generate inefficiency in the use of scarce economic resources. Inefficiency is unethical: doctors who use resources inefficiently deprive potential patients of care from which they could benefit. To eradicate unethical and inefficient practices two economic rules have to be followed: (i) no service should be provided if its total costs exceed its total benefits; (ii) if total benefits exceed total costs, the level of provision should be at that level at which the additional input cost (marginal cost) is equal to the additional benefits (marginal benefit). This efficiency test can be applied to health care systems, their component parts and the individuals (especially doctors) who control resource allocation within them. Unfortunately, all health care systems neither generate this relevant decision making data nor are they flexible enough to use it to affect health care decisions. There are two basic varieties of budgeting system: resource based and production targeted. The former generates obsession with cash limits and too little regard of the benefits, particularly at the margins, of alternative patterns of resource allocation. The latter generates undue attention to the production of processes of care and scant regard for costs, especially at the margins. Consequently, one set of budget rules may lead to cost containment regardless of benefits and the other set of budget rules may lead to output maximization regardless of costs. To close this circle of inefficiency it is necessary to evolve market-like structures. To do this a system of client group (defined broadly across all existing activities public and private) budgets is advocated with an identification of the budget holder who has the capacity to shift resources and seek out cost effective policies. Negotiated output targets with defined budgets and incentives for decision makers to economise in their use of resources are being incorporated into experiments in the health care systems of Western Europe and the United States. Undue optimism about the success of these experiments must be avoided because these problems have existed in the West and in the Soviet bloc for decades and efficient solutions are noticeable by their absence.
