Compare and Contrast

I have been in Infectious Diseases for almost 25 years. I have two major jobs: I see inpatient consults and I chair the Infection Control program. I have been involved in quality improvement, especially as it relates to hospital acquired infections, for my entire career. It has been an interesting quarter century. Year after year we have driven down infection rates and other kinds of mortality and morbidity in hospitalized patients. Everyone recognizes that medicine is difficult and dangerous and its biggest problem is medicine is practiced by humans, who, I would venture to observe, are prone to mistakes and any number of cognitive errors.

It has not been a easy journey. People hate change and there has not always been certainty as to the best options to choose to solve a problem, a problem that continues today. For example, how best to treat a patient with potential methicillin resistant Staphylococcus aureus colonization (MRSA). Should we screen everyone? Screen high risk patients? Surgical patients? Do we decolonize, with the long term consequence of accelerating antibiotic resistance? Do we place everyone with MRSA in isolation, with the known decrease in care that patients in isolation may have? Everything we do has potential downsides and unintended consequences. No good deed ever goes unpunished.

A Disconnect between cell phone fears and science

Disconnect: The Truth About Cell Phone Radiation, What the Industry Has Done to Hide It, and How to Protect Your Family by Devra Davis, PhD is touted as a book about the issue of cell phones and health. It is instead a tract that conspiracy theorists will love that sheds no objective light on the often confusing scientific data in this area. The tag line on the jacket sets the tone: The TRUTH about cell phone RADIATION. What the INDUSTRY has done to hide it, and how to PROTECT your FAMILY. In the area of EMF and health, there are a certain number of studies that appear to find biological “effects”. This is perfect fodder for alarmists like Davis, who ignore the fact that virtually none of these “effects” have been reproduced in follow up studies. If you were expecting an objective review of the often confusing scientific data in this area, you should avoid this book.

Disconnect focuses almost exclusively on studies that support its alarmist conclusions while either ignoring or falsifying information about studies showing no harm. The quality of scientific studies varies greatly. Disconnect is highly selective and totally biased in discussing only studies that support its point of view, it rejects contrary studies accepted by the majority of mainstream scientists as the product of some vast conspiracy, and it completely misstates the findings of key studies that find no harm from cell phones. She interviewed only a relatively small group of dissident scientists who are outside of the mainstream. The book is completely lacking in objectivity.

Major Factual Misstatements

There are so many things wrong in Disconnect that it is difficult to know where to begin. We will start by reviewing a few of the most blatant examples of how it misrepresents key findings of some of the most important cell phone studies.
