Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

76
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Systematic Error: Methodological and Sampling Errors

5.4K
In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Summary

Extended Focused Assessment with Sonography for Trauma (eFAST) exams are highly accurate in unstable trauma patients. Common errors leading to false results include issues with pelvic fluid, double-line sign, pericardial fat pad, and thoracic eFAST views.

Area of Science:

  • Emergency Medicine
  • Diagnostic Imaging
  • Trauma Care

Background:

  • Extended Focused Assessment with Sonography for Trauma (eFAST) is crucial for unstable trauma patients.
  • Quality assurance is essential for maintaining the accuracy of eFAST examinations.

Purpose of the Study:

  • To identify common causes of false positive and false negative eFAST exams.
  • To analyze six years of eFAST quality assurance data.

Main Methods:

  • Retrospective observational cohort study.
  • Analysis of eFAST exams from trauma activation patients at a Level 1 trauma center.
  • Comparison of eFAST findings with computed tomography (CT) imaging.

Main Results:

  • Over 4800 eFAST exams were reviewed; 29.8% were incomplete or undocumented.
  • False positive rate was 0.79% and false negative rate was 2.19% after exclusions.
  • Common error sources included pelvic fluid, double-line sign, pericardial fat pad, and thoracic eFAST views.

Conclusions:

  • eFAST exams demonstrate high accuracy in trauma patients.
  • Poor documentation and technical limitations significantly impact eFAST exam quality.
  • Specific anatomical findings are frequent sources of diagnostic errors in eFAST.
