Keeping Up with the Medical Literature

ScienceDirect - My AlertsGoogle Med

“Google is a good Diagnostician”

BMJ  2006;333 (2 December) Using signs and symptoms as search terms on Google

finds the correct diagnosis 57.7% of the time (95% confidence interval 38.3% to 77.1%) say Tang and Ng.

The authors identified 26 case reports published in a single journal and selected three to five specific symptoms and signs from each to be used as Google search terms. They compared Google results with the original diagnoses. Google searching is less helpful in identifying complex diseases with non-specific symptoms than in diagnosing illnesses with unique symptoms.

Basic Principles

Core standards for the digital world should be similar to the world of print

Physician as Interpreter of medical information (patients have the same information we do)

Evaluating Medical Web Sites

“Assessing, controlling, and assuring the quality of medical information on the Internet: Caveat lector et viewer- let the reader and viewer beware.” – Article from JAMA 1997; 277:1244-5

Physician/Patient Uses

Interaction of the two…

Prostate Cancer Case

Questions: age, ethnic group, family history, height, vasectomy history (he had one), and dietary habits (<5 servings of tomato based foods a week and <5 servings of food with animal fat a day).

Risk is above averageCalled me

Web Based Risk Calculators

New Information resourceAdvantages:

– Tailored risk info based on personal factors

Disadvantages:– Accuracy?– Balanced?

Clarity about Risk

What risk is under consideration: dying of the disease or getting it?

Probability (a number)?Time period associated with this

probability?The site doesn’t tell Mr. Smith the chance

he will get or die of prostate ca in a defined time frame.

Advantage: Broad array of cancers, time frameDisadvantages: Tailored only to age, sex, and

raceOver the next 10 years, a 55y.o. white man’s:

– Chance of getting prostate ca is 40 in 1000– Chance of dying of prostate ca is 2 in 1000

Context

How this risk c/w chance of dying of other cancers

Risk Charts: His chance of dying of:– Colon Cancer: 4 in 1000

– Heart Disease: 20 in 1000 (50 if smokes)

– Anything: 93 in 1000 (217 if smokes) in the same time frame.

– Journal of the National Cancer Institute, Vol. 94, No. 11, 799-804, June 5, 2002

Uncertainty

Strength of evidence behind the factors used in generating risk estimates:– Age consistently important for prostate ca– Height, diet, and vasectomies not consistently

important• Yet these were included in his initial risk calculator

Communicating Risk:the main work of doctors

Web based risk calculators demonstrate a paradigm shift in medicine.

Physicians are moving from primary medical information providers to information managers.
