23 CP Closing Thoughts We must begin to regulate ourselves by eliminating inappropriate tests, reducing procedures and care that have marginal benefit, improving quality

24 CP Closing Thoughts Required major fix of the health care system will be painful – the longer we wait, the more painful it will be
