Primary care has come into the limelight with the passage of the Patient Protection and Affordable Care Act, the unchecked and unsustainable rise in American health care expenditures, and the crest of Baby Boomers who are now Medicare-eligible and entering the most health care–intensive period of their lives. Yet how much is really known about primary care? What Matters in Medicine: Lessons from a Life in Primary Care is a look at the past, present, and future of general practice, which is not only the predecessor to the modern primary care movement, but its foundation. Through memoir and conversation, Dr. David Loxterkamp reflects on the heroes and role models who drew him to family medicine and on his many years in family practice in a rural Maine community, and provides a prescription for change in the way that doctors and patients approach their shared contract for good health and a happy life. This book will be useful to those on both sides of primary care, doctors and patients alike.
