The Legal Status of Clinical Practice Parameters: An Annotated Bibliography

Abstract

An important recent development in American medicine has been the strong push in the last few years toward the formal creation, dissemination, and enforcement of explicit clinical practice guidelines or parameters relating to the quality and efficacy of various medical interventions, parameters that would guide the decisions and actions of physicians and other health care providers (1-3). Medical societies (4), governmental agencies such as the federal Agency for Health Care Policy and Research, and insurers are utilizing a variety of approaches to the develop ment of practice parameters for medical diagnosis and intervention, including informal consensus de velopment, formal consensus development, evidence- based guideline development, and explicit guideline development (5). The number and variety of practice parameters has burgeoned in response to the wide national variations in medical practice patterns, without corresponding differences in clinical out comes, that have been documented by health services researchers.

Several commentators have expressed serious skepticism about the probable impact of practice pa rameters, surmising that they will be used extensively in a negative manner in medical malpractice litiga tion (6, 7). Many physicians in particular have asked "how they [practice parameters] can be implemented without courting the ruin of the individual practi tioner" (8).

In response to these anxieties, a new medicolegal literature has arisen to address the relationship be tween the development of clinical practice parame ters and the physician's exposure to malpractice liti gation and adverse judgments, as well as the impli cations for malpractice insurance premiums. This growing literature has now achieved a critical mass. The major contributions to this corpus at present are listed and annotated below.
