Excerpt: Despite a landmark report a decade ago detailing the deadly nature of the U.S. health system, a consumer group said Tuesday, May 19, that little has been done to prevent the errors that still kill as many as 100,000 patients each year -- a number that the group said is a conservative estimate. Consumers Union, which publishes the magazine Consumer Reports, published what it called a 'review of the scant evidence' of the health system's efforts to reduce preventable errors that cost the country $17 billion to $29 billion annually, a cost borne by the employers that pay for shoddy care.
