A Medical Terms List

Program Service Payments – Program Service Payments are payments made to a contractor or provider for the provision of health-related services. Program Guidelines – Program Guidelines set down the administrative arrangements and specify the control requirements for the management of specific programs.

The committee’s definition of appropriate care does not require that guidelines be based on judgments about the cost-effectiveness of particular clinical practices; neither does it preclude it. The committee’s decision not to incorporate an explicit reference to costs in the definition of practice guidelines or appropriate care reflects a value judgment that was not shared by all committee members. The majority, however, believed that the emphasis on clinical decision-making should be paramount. CAROTID SINUS – Slight dilatation on the common carotid artery at its bifurcation containing nerve cells sensitive to blood pressure.

In English, the most common vowel used in the formation of the combining form is the letter -o- added to the word root. For example, if there is an inflammation of the stomach and intestines, this would be written as gastro- and enter- plus -itis, gastroenteritis. Given the multiple common meanings of the term and the paucity of professional and technical usage, the committee decided to offer only a provisional definition of performance measures. As practice guidelines and related evaluation instruments are more widely developed and used, a different or more specific meaning for this term may emerge. The committee did not, for example, discuss whether different principles and translation strategies might be needed for guidelines that focus heavily on nursing care compared to those that mainly emphasize care provided by physicians. The recent IOM report on quality assurance in the Medicare program discusses some of the attributes that good review criteria should have.
