RT Journal Article SR Electronic T1 Education, practice reviews needed to reduce surgical intervention, Quebec report says JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 463 OP 464 VO 155 IS 4 A1 Rafuse, J. YR 1996 UL http://www.cmaj.ca/content/155/4/463.abstract AB Clinical uncertainty may be the reason for large variations in the rates of tonsillectomy, adenoidectomy and myringotomy in Quebec, a report prepared for the provincial government states. Methods used in other jurisdictions, such as informing physicians about geographic differences in intervention rates and developing clinical practice guidelines, could reduce the variations and save millions of dollars, researchers suggest.
