Contrast sensitivity vs specificity. d. Analyze the different levels of scientific evidence. e. Revise clinical practice guidelines. Bibliography: McGee Steven. Evidence-Based Physical Diagnosis, 5th ed Elsevier; 2022. Chapter 1. Available at ClinicalKey 2 EVIDENCE BASED CLINICAL PRACTICE To diagnose is to categorize illness, based on the clinical problems. Overcoming disease implies understanding it. The methodology of making patient care decisions using the best available evidence. McGee Steven. Evidence-Based Physical Diagnosis, 5th ed Elsevier; 2022. Chapter 1. Available at ClinicalKey Al-Ghimlas F. The philosophy of evidence-based clinical practice: Is evidence enough? Ann Thorac Med. 2013 Jul;8(3):131-2. doi: 10.4103/1817-1737.114282. PMID: 23922606; PMCID: PMC3731853. What is the diagnostic value of the traditional physical examination? Is it outdated and best discarded? Is it completely accurate and underutilized? Is the truth somewhere between these two extremes? There are still abundant diagnosis depending on clinical examination itself. A technologic test provides findings, which could increase or decrease probability of disease. McGee Steven. Evidence-Based Physical Diagnosis, 5th ed Elsevier; 2022. Chapter 1. Available at ClinicalKey Evaluating Diagnostic Accuracy of Physical Findings The diagnostic accuracy of physical findings is assessed by comparing the test results to the patient's true disease status. Positive and negative findings, shift probability of disease. Starting point: pre-test probability. Higher discriminatory power of physical signs comes from sensitivity and specificity. McGee Steven.

The steps in evidence-based practice begin with asking a clinical question (diagnosis, treatment) and acquiring the evidence. When performing a literature search, one can align articles found with their original clinical question to deem whether the article may provide useful evidence.
