Managing dental care versus managed dental care: looking south from north of the 49th parallel.

In the United States, aggregate expenditures on the largely private health care system, as a proportion of Gross National Product, exceed those of all other countries. Under private enterprise, the health care system in the United States grew as predicted by the underlying equation that more service volume equates to more revenue for hospitals and providers. Managed care is the response of for-profit health care organizations to meet the demands of U.S. corporations to contain the escalating costs of hospital, medical and other health care benefits for their employees. Managed health care has several models, but preferred provider organizations (PPOs) have been the model that has increased most rapidly. In contrast, managers of Canadian public dental programs plan, organize, direct and control more of the structures, processes and outputs to achieve desired outcomes for special groups. In Canada, the approaches to quality assurance, restraint of trade and the power of the professional lobby are different from the approaches in the United States. Nonetheless, the context of private dental care plans is very similar to the context that produced managed health care in the United States. Better management to meet demonstrated needs with evidence-based care can result in sustainable, adequately financed plans and avoid the deep-discount form of managed dental care.
