research and objectives

LDI conducts an integrated, collaborative research program in health care evaluation, delivery, economics, management, and policy.

LDI's research objectives are to:

    bulletAdvance fundamental knowledge of issues central to the improvement of health care delivery through better understanding of the efficient allocation of health resources, appropriate uses of those resources, and development of innovative health care delivery systems; and;

    bulletGuide and influence health policy at the national, state, local, and organizational levels such that those policies lead to more efficient and equitable health care for the public.

LDI's research is focused in three primary areas:
    bullet Evaluation of health care interventions: The effectiveness and appropriateness of medical practice contribute significantly to the quality, outcome, and cost of care. Areas being investigated include the adoption and diffusion of new technologies, the cost-quality trade-offs in health care, and the cost effectiveness of medical interventions.

    bullet Financing, organization, delivery, and management of care: Providing affordable, quality health care to all Americans requires that financial and other barriers to access be eliminated. These barriers include insufficient alternative delivery systems, inefficient regulation, and lack of sufficient information to users of health care. LDI Senior Fellows examine factors that influence the demand for and supply of care, health care financing, management of systems, workforce issues, the economic implications of health expenditures, and resource use.

    bullet Changing provider and patient behavior: Increased competition and resource constraints influence institutional growth, structure, and adaptability, and impact on provider and patient behavior. LDI Senior Fellows are investigating how provider payment, clinical protocols and guidelines, ambulatory DRGs, resource-based relative value scales, volume performance standards, and organizational and administrative interventions influence provider, patient, and institutional decision making and behavior.
