This report is about setting priorities for health technology assessment (HTA). HTA examines systematically the consequences of the application of health technologies (broadly defined to include any health care intervention) to support decision making in policy and practice. Only a fraction of existing health technologies have been formally evaluated, and many more appear each year. Resources for HTA are, however, limited so that priorities have to be set, whether explicitly or implicitly. The aim of setting priorities for HTA should be to identify those assessments that offer the greatest benefits in relation to their cost, and thus to maximize the benefit derived from investments in HTA.

Health technology assessment (HTA) is primarily concerned with the consequences (benefits and costs) of health care and health policy decisions. Because decision making is complex and outcomes are often uncertain, it is helpful to attempt to assess the consequences. The quality of decisions can be improved by a process that provides a consistent framework for identifying and assessing health technologies.

The objective of health technology assessment (HTA) is to support decision making in health care. HTA does not claim to provide a definite solution to a health care problem, but to assist decision makers with evidence-based information about the clinical, ethical, social, and economic implications of the development, diffusion, and use of health care technology.

The issue of health benefits coverage—and its relation to health technology assessment (HTA)—has gained increasing attention in recent years. Economic constraints on health care, as well as the rapid pace of technological change, have forced European countries to face difficult choices in providing such care. The active use of coverage decision making has been proposed as a tool to help rationalize health care, and HTA has been advocated as a necessary activity to improve coverage decisions.

A literature review compared the results of different kidney function tests using the inulin clearance or similar methods as a gold standard. The methodological strength of the available studies was weak. For the time being, the calculated creatinine clearance using formula, is a first choice, especially in general practice.

We examined the use of percutaneous transluminal coronary angioplasty, kidney stone lithotripsy, and bone marrow transplant among patients with different health insurance plans in California. HMO enrollees were less likely to receive these procedures compared with fee-for-service patients. Our results have implications for the inflationary effects of technology under managed care.

A review of 39 articles found no consensus on indication for laparoscopic assisted vaginal hysterectomy (LAVH) compared with traditional approaches. Since only three randomized trials comparing LAVH with traditional methods exist, the scientific basis for surgical choice is lacking. Uncontrolled studies indicated that outcomes following LAVH were not superior to vaginal hysterectomy and costs were significantly higher.

Evaluating the impact of computer-based medical information systems requires not only an understanding of computer technology but also an understanding of complex social and behavioral processes. This essay discusses the need for evaluation of health care information systems, a set of evaluation questions based on assumptions about the impact of technology on organizations, and recommendations for reducing barriers to the implementation of health care information systems.
