Extract

In law, with rare exception such as legislative action, change is evolutionary and methodical. Unlike biomedical science where a breakthrough can quickly lead to dramatic changes in medical practice, legal precedent is more adherent and must evolve either through the legislative process or on a court by court basis in case law. Nevertheless, compelling evidence will pave the road to change within the law. Health care research conducted over the last three decades has produced a body of empirical evidence that suggests an overhaul of our current legal standards of informed consent is overdue.

This article uses health services research to examine the fundamental assumptions of our current informed consent laws and propose legal reform. Much has been written on how to bring the law to bear on medical practice in order to improve patient rights and protect physicians, but far less has been done to bring the practice of medicine to inform our legal standards. Prior legal scholarship on informed consent has made arguments regarding reform from both ethical and legal perspectives; however, only a small few have incorporated clinical and health services research as well as ethical and legal principles to analyze informed consent.

Typically, statistically significant results must have a 95% or higher probability that the results in the given data did not occur by chance. A ‘p’ value of .05 signifies that there is a 95% probability that the finding of these results did not occur by chance. Generally, in order to have statistical signicance, ‘p’ must be less than or equal to .05.
