Evidence Based Primary Care

This application lists over 400 laboratory tests, physical exam findings, history findings,
and radiological studies for the most frequent diseases encountered in the primary care
setting. For each entry, measures of the test’s efficacy found in the medical literature
are reported. These metrics include: Sensitivity, Specificity, Positive Predictive Value,
Negative Predictive Value, Positive Likelihood Ratio, and Negative Likelihood Ratio.
It also includes a calculator that will translate the Pre-test Probability into a Post-test
Probability in the event of either a positive or negative test result.

The database is categorized both by test and by disease. The tests are further divided into
three categories: Laboratory, History/Physical Exam, and Radiology. The Pubmed entry
where the data was found is listed with each result, along with a brief description of the
paper.

A short explanation of the evidence-based metrics is also available in the Information
section.
