Physicians practicing evidence-based medicine need to be able to appraise a new study and determine whether the results warrant sufficient certainty to the level that they can be applied to patient care. Without such appraisal, misleading results can be incorporated into patient care, which can lead to inefficient, costly, and possibly harmful care. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach offers a modern framework that can be applied to evaluate the trustworthiness of evidence. In this guide, we present a simplified approach based on GRADE; in which we call on readers of the medical literature to pay attention to six domains before making an overall judgment about the trustworthiness of results and before applying the evidence to patient care.

The recent advances in diagnostic pulmonary procedures have revolutionized the evaluation of abnormal thoracic findings including lung nodules and masses, mediastinal lymphadenopathy, and pleural diseases. Bronchoscopies with endobronchial ultrasonography and electromagnetic navigation are examples of new technology that has significantly improved the specificity and sensitivity of these procedures in diagnosis and staging of lung cancer without the need for more invasive procedures. This report describes the different diagnostic pulmonary interventions providing a description of the procedures, their indications, diagnostic yield and drawback.
