From Booklist

*Starred Review* Health policy expert Welch’s assertions about the benefits of some of modern medicine’s most popular diagnostic screening tools are unlikely to ingratiate him with many people. He claims that overdiagnosis “is the biggest problem posed by modern medicine,” and backs that assertion up with a barrage of facts, charts, and graphs. This is information, he says, that is downplayed or simply ignored by individuals and groups promoting the notion that earlier diagnosis—whether for prostate cancer or diabetes—translates to better health. Indeed, Welch says, just the converse is more often true. In an overwhelming number of circumstances, early diagnosis turns healthy, asymptomatic people into patients who require a variety of medical interventions with no benefit, even exposing them to unnecessary harm. Worse, overdiagnosis can render perfectly healthy people uninsurable. Furthermore, instead of lowering health-care costs, all those scans, screenings, and tests actually raise costs by overtreating people who will never benefit from said treatment. His point is that both physicians and patients need to be skeptical and understand all the data (pro and con) surrounding prescreening for possible illness. Welch speaks his truth with a frankness and clarity scant found in today’s hysteria over medical prescreening. –Donna Chavez

Review

Overdiagnosed —albeit controversial—is a provocative, intellectually stimulating work. As such, all who are involved in health care, including physicians, allied health professionals, and all current or future patients, will be well served by reading and giving serious thought to the material presented.”─ JAMA

“Everyone should read this book before going to the doctor! Welcome evidence that more testing and treatment is not always better.”─ Susan Love, MD, author of Dr. Susan Love’s Breast Book
 
“This book makes a compelling case against excessive medical screening and diagnostic testing in asymptomatic people. Its important but underappreciated message is delivered in a highly readable style. I recommend it enthusiastically for everyone.”─ Arnold S. Relman, MD, editor-in-chief emeritus, New England Journal of Medicine, and author of A Second Opinion: Rescuing America’s Health Care
 
“This stunning book will help you and your loved ones avoid the hazards of too much health care. Within just a few pages, you’ll be recommending it to family and friends, and, hopefully, your local physician. If every medical student read Overdiagnosed, there is little doubt that a safer, healthier world would be the result.”─ Ray Moynihan, conjoint lecturer at the University of Newcastle, visiting editor of the British Medical Journal, and author of Selling Sickness
 
“An ‘overdiagnosis’ is a label no one wants: it is worrisome, it augurs ‘overtreatment,’ and it has no potential for personal benefit. This elegant book forewarns you. It also teaches you how and why to ask, ‘Do I really need to know this?’ before agreeing to any diagnostic or screening test. A close read is good for your health.”─ Nortin M. Hadler, MD, professor of medicine and microbiology/immunology at University of North Carolina at Chapel Hill and author of Worried Sick and The Last Well Person
 
“We’ve all been made to believe that it is always in people’s best interest to try to detect health problems as early as possible. Dr. Welch explains, with gripping examples and ample evidence, how those who have been overdiagnosed cannot benefit from treatment; they can only be harmed. I hope this book will trigger a paradigm shift in the medical establishment’s thinking.” —Sidney Wolfe, MD, author of Worst Pills, Best Pills and editor of WorstPills.org

Conventional wisdom is that more diagnosis, especially early diagnosis, means better medical care. Reality, says Dr. Gilbert Welch – author of "Overdiagnosed," is that more diagnosis leads to excessive treatment that can harm patients, make healthy people feel less so and even cause depression, and add to escalating health care costs. In fact, physician Welch believes overdiagnosis is the biggest problem for modern medicine, and relevant to almost all medical conditions. Welch devotes most of his book to documenting his concerns via examples of early diagnosis efforts for hypertension, prostate cancer, breast cancer, etc. that caused patient problems.

Welch provides readers with four important and generalizable points. The first is that, while target guidelines are set by panels of experts, those experts bring with them biases and sometimes even monetary incentives from drug-makers, etc. Over the past decades many target levels have been changed (eg. blood pressure, cholesterol levels, PSA levels), dramatically increIDg the number classified as having a particular condition. (Welch adds that prostate cancer can be found at any PSA level – about 8% for those with a PSA level of 1 or less, over 30% for those with a level exceeding 4; most are benign.)

The second is that treating those with eg. severe hypertension benefits those patients much more than treating those with very mild hypertension or ‘prehypertension;’ the result is treating those with lesser ‘symptoms’ can easily cause new problems that outweigh the value of the hypertension treatment.

The third is that Welch believes it is usually more important to treat those with disease symptoms (eg. pain) than those without.
I read Overdiagnosed this morning, and I strongly urge you to read it, too. If you’ve ever wondered why our country’s healthcare costs are skyrocketing even though our health outcomes lag behind the rest of the industrialized world, this book has the answers. We are overtested, overdiagnosed and overtreated. But sadly and paradoxically, this intensive use of "preventive" medicine has not improved our physical health or sense of well being — it has diminished it.

Dr. Welch builds a strong case that Americans are overdiagnosed in a clear, concise and compelling way. He provides anecdotal accounts of people who were seriously harmed by the overzealous use of modern, high tech testing. And he backs these stories up with findings from landmark medical research studies. As we move from chapter to chapter and disease to disease, we see the same patterns emerge: thresholds for "illness" are lowered and suddenly tens of millions of people are diagnosed and treated for mild or nonexistent "diseases" that never would have harmed them.

Dr. Welch identifies the key players who brought American medicine to this sorry state — big pharma and medical products manufacturers hungry to increase profits, doctors who order unnecessary tests to avoid malpractice lawsuits, and overzealous patient advocacy groups who press for action in the absence of any scientific evidence of improved outcomes.

Dr. Welch explains key concepts like "lag time bias" and "overtreatment bias" that enable you to see why the benefits of aggressive preventive medicine are far less than you have been led to believe. Once you understand terms like these, you will never again be swayed by misleading advertising or public health campaigns.

I’m in the Air Force and my job required me to pass the SY0-401. Many people failed with the book that was given to us, but this book helped me pass with an 806. Good luck to all who takes the test!

Another great study guide by Darril Gibson. Passed the Sy0-401 with just this book and 2 weeks of time. The test has some questions that i know i got wrong but i disagree with the way they worded it. I finished the test in about an hour. My advice is to read the question once, choose your answer, and all the possible choices followed by the question again. I got tripped up a couple of times on the wording, of what exactly they wanted and only after rereading the possible answer choices did I realize their request. They also have a few simulation questions without going into greater detail some of these were great others were a headshaking why.
Darril also has a twitter feed that you can follow for updates and more information around study material. Even if you’re not taking the test and want to learn more about Security, for under $10.00 its really a great cost for what your learning and having all organized in a way that will permit an east pass on the test.

Mr. Gibson has hit another home run with this installment of his CompTIA Security+ Get Certified Get Ahead: SY0-401 Study Guide. Covering all of the new material added to the latest set of objectives, this guide is well written and logically organized. Explanations of key concepts are clearly articulated and insightful. The practice questions are properly created and very useful for preparing for the exam. I especially love the Remember This tips found throughout the guide. In fact, students of Security+ would be wise to memorize each one of them.
As an active CompTIA Certified Technical Trainer who has trained hundreds of students on Security+, I recommend this guide to my students each week without hesitation. Too bad I can’t just teach directly from Mr. Gibson’s materials for my Security+ and Network+ courses. His study materials are excellent.
