But in some cases, the fox has been left to guard the hen house, and the concept of guidelines is getting flipped on its head by some in the medical community including device manufacturers. We will inspect the recent actions taken by many states, look at who and what has driven the decisions to adopt various guidelines, what role evidence-based medicine has played, how the trend has evolved, and outcomes resulting from various strategies. Case studies will reference positive and negative experiences among Arizona, Georgia, New York, Oklahoma, Louisiana, Montana, Kansas, Texas, North Dakota, Ohio and California. Never before has this national story been synthesized and illustrated in such revealing fashion, delivered as part of ODG "In the Know" with Phil LeFevre, a careful observer, active participant and effective narrator for this timely tale.
