Validation method.

OK I've just finished listening to that, it left me wishing for a little more depth and discussion but I suppose there is only so much you can fit in 1/2 hour. I just can't see how their success can be duplicated in the average nursing home with high staff turnovers and where you often don't see the same caregiver with any consistency.

That would be on cbc radio, not cbc tv. Maybe easier to google "White Coat, Black Art". Thanks for the tip.
