Snowball in a Blizzard

Snowball in a Blizzard

A Physician's Notes on Uncertainty in Medicine

There’s a running joke among radiologists: finding a tumor in a mammogram is akin to finding a snowball in a blizzard. A bit of medical gallows humor, this simile illustrates the difficulties of finding signals (the snowball) against a background of noise (the blizzard). Doctors are faced with similar difficulties every day when sifting through piles of data from blood tests to X-rays to endless lists of patient symptoms.

Diagnoses are often just educated guesses, and prognoses less certain still. There is a significant amount of uncertainty in the daily practice of medicine, resulting in confusion and potentially deadly complications. Dr. Steven Hatch argues that instead of ignoring this uncertainty, we should embrace it. By digging deeply into a number of rancorous controversies, from breast cancer screening to blood pressure management, Hatch shows us how medicine can fail-sometimes spectacularly-when patients and doctors alike place too much faith in modern medical technology. The key to good health might lie in the ability to recognize the hype created by so many medical reports, sense when to push a physician for more testing, or resist a physician’s enthusiasm when unnecessary tests or treatments are being offered.

Both humbling and empowering, Snowball in a Blizzard lays bare the inescapable murkiness that permeates the theory and practice of modern medicine. Essential reading for physicians and patients alike, this book shows how, by recognizing rather than denying that uncertainty, we can all make better health decisions.

Praise

"Uncertainty lies at the heart of modern medicine in ways that most physicians--not to mention their patients--often fail to recognize. Fundamental imperfections in our understanding of health and disease limit doctors' ability to combat illness. Hatch, an assistant professor of medicine at the University of Massachusetts Medical School, argues that physicians who ignore this uncertainty often overtreat their patients, resulting in sometimes harmful, even fatal consequences. By the same token, far too many patients assume that more medical care is always better than less, thereby seeking or consenting to toxic treatments that trigger needless suffering. Hatch provides examples from such fields as breast cancer, cardiology and infectious disease. He also offers straightforward rules of thumb to help readers navigate medical advice."—Scientific American
