RT Journal Article SR Electronic T1 Commentary: Helling v. Carey, Caveat Medicus JF Journal of the American Academy of Psychiatry and the Law Online JO J Am Acad Psychiatry Law FD American Academy of Psychiatry and the Law SP 306 OP 309 VO 36 IS 3 A1 D. Clay Kelly A1 Gina Manguno-Mire YR 2008 UL http://jaapl.org/content/36/3/306.abstract AB Forensic experts should be aware of the increasing importance of clinical practice guidelines (CPGs) in various legal settings. CPGs are a type of learned treatise and are accepted into court proceedings under hearsay exception provisions. The courts now use CPGs as shorthand for the standard of care in making malpractice determinations. However, medical guidelines can function as a sword or a shield in the courtroom arena. The Helling v. Carey medical malpractice case serves as a frightful reminder of the potential consequences of allowing courts to craft their own standards of medical care.
