[Diagnostic delay of pulmonary embolism]

Area of Science:

• Medical diagnostics
• Pulmonary embolism research
• Healthcare systems analysis

Background:

• Pulmonary embolism (PE) diagnosis involves multiple stages, each contributing to potential delays.
• Understanding diagnostic timelines is critical for improving patient outcomes and healthcare efficiency.

Purpose of the Study:

• To quantify diagnostic delay stages for pulmonary embolism (PE).
• To identify clinical factors influencing diagnostic delays in PE patients.

Main Methods:

• A retrospective case series analysis of 261 PE patients diagnosed between January 2008 and December 2009.
• Data collection included symptom onset, primary care presentation, secondary care referral, and diagnosis dates.
• Multivariate logistic regression analyzed the relationship between diagnostic delay and clinical parameters.

Main Results:

• The average total diagnostic delay for PE was 8.6 days.
• Patient delay (4.2 days) and primary care delay (3.9 days) were the main contributors.
• Symptoms like chest pain and deep venous thrombosis signs correlated with earlier diagnosis, while dyspnea and comorbidities influenced delays.

Conclusions:

• Substantial diagnostic delays in pulmonary embolism (PE) exist, primarily in patient and primary care stages.
• Further research is needed to identify clinical indicators for earlier PE suspicion in primary care.
• Developing improved diagnostic models is essential to reduce overall PE diagnostic timelines.
