Manitoba has begun to respond to overuse of its health care system by forcing people who visit too many doctors or pharmacies to limit their use to one doctor and one drugstore. The province reviewed the records of patients who made more than 67 office visits in a year and/or saw more than 12 physicians annually. The heaviest user made 247 office visits to 71 different physicians in 1 year. The new restriction applies to about 28 patients. The move is expected to save the province $116,000.
