Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

148
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...

Pulmonary Embolism III: Nursing Management

186
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Pulmonary Embolism I: Introduction

338
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Area of Science:

  • Health Informatics
  • Human-Computer Interaction
  • Medical Decision Making

Background:

  • Clinical Decision Support Systems (CDSS) enhance patient care efficiency, cost-effectiveness, and guideline adherence.
  • Clinician-developed CDSS concepts may overlook crucial design details.
  • Human-Centred Design (HCD) offers systematic methods for robust CDSS development.

Purpose of the Study:

  • To highlight the application of HCD approaches in the development of a pulmonary embolism CDSS.
  • To demonstrate how HCD integrates multidisciplinary expertise for improved CDSS design.

Main Methods:

  • Collaborative development involving computer science, psychology, and medicine.
  • Utilized HCD methods: pre-clinical prototype evaluation, iterative usability expert reviews, and formative usability testing.
  • Incorporated findings from a separate clinical pilot study.

Main Results:

  • HCD iteratively refined the CDSS for ease of use and functional soundness.
  • Identified and addressed issues with cognitive workflow alignment, missing features, and interface clarity.
  • Optimized information hierarchy, user-specific support levels, and language within the decision support tool.

Conclusions:

  • HCD methods were crucial for creating a user-friendly and effective pulmonary embolism CDSS.
  • Leveraging HCD revealed design considerations that might otherwise have been missed.
  • The study supports the integration of HCD in future CDSS design for enhanced clinical practice.
