Unlocking Faster Diagnosis: How Healthcare is Tackling Pulmonary Embolism and DVT Delays

Avery Sinclair in Health & Wellness July 2025 • 4 min read.

"New research illuminates the path to quicker, more effective diagnosis and treatment of critical conditions."

In the fast-paced environment of emergency medicine, time is of the essence. The faster a diagnosis, the quicker a patient can receive the right treatment, especially when dealing with life-threatening conditions like pulmonary embolism (PE) and deep vein thrombosis (DVT). Recent research is shedding light on innovative approaches to accelerate diagnosis and treatment, improving patient outcomes and optimizing healthcare resources.

Two key studies provide valuable insights. One focuses on the prevalence and prognosis of delayed PE diagnosis, while the other examines the impact of electronic clinical decision support (eCDS) in expediting PE diagnosis across different healthcare settings. Each study offers a unique perspective on how healthcare professionals can enhance their diagnostic processes and treatment strategies.

These advancements matter because delays in diagnosing PE and DVT can lead to severe complications, increased mortality rates, and higher healthcare costs. By understanding the factors contributing to these delays and implementing effective solutions, medical professionals can provide more efficient and safer care.

The Concerning Prevalence of Delayed Pulmonary Embolism Diagnosis

A multi-center retrospective cohort study, conducted across 18 community emergency departments, investigated the prevalence and prognosis of delayed PE diagnosis. The study included 2,700 patients, with a significant subset experiencing a delay in diagnosis. Researchers compared outcomes between patients whose diagnosis was delayed and those who received prompt attention. Specifically, the study focused on patients presenting with PE-related complaints, such as chest pain, shortness of breath, and syncope, within the 14 days leading up to their diagnosis.

The results indicated that delayed PE diagnosis is indeed a common issue. Out of the 2,700 patients, 806 had at least one in-person encounter for PE-related complaints in the two weeks prior to their diagnosis. Of these, 293 patients were sent home without a PE diagnosis, highlighting a missed opportunity for timely intervention. This diagnostic delay had a median duration of 5 days, underscoring the potential risks associated with delayed treatment.

Study Scope: Included 2,700 patients across 18 community EDs.
Complaint Window: Analyzed encounters within 14 days prior to diagnosis.
Delayed Group: 293 patients sent home without initial PE diagnosis.
Median Delay: 5 days between initial encounter and diagnosis.

Despite the delay, the study found that patients in the delayed diagnosis group did not experience significantly worse outcomes compared to those diagnosed promptly. This included similar rates of high-risk categorization, length of stay, ED disposition, and all-cause mortality within 30 days. However, the authors emphasize that the lack of worsened outcomes does not diminish the need for improved early detection methods. The study suggests that opportunities exist to enhance the recognition of PE symptoms and expedite diagnosis in both emergency departments and outpatient settings.

Embracing Technology and Teamwork for Better Patient Outcomes

The studies presented highlight the potential for improving the diagnosis and treatment of pulmonary embolism and deep vein thrombosis. By leveraging electronic clinical decision support tools and fostering multidisciplinary collaboration, healthcare systems can reduce diagnostic delays, improve patient outcomes, and ensure that patients receive timely and appropriate care. Further research and implementation efforts are essential to translate these findings into widespread improvements in clinical practice.

Everything You Need To Know

What exactly is a pulmonary embolism and why is it so important to diagnose it quickly?

Pulmonary embolism, or PE, is a condition where a blood clot blocks one or more arteries in the lungs. This blockage can prevent oxygen from reaching the body's tissues and organs, potentially leading to serious complications or even death. Rapid diagnosis is critical because the faster treatment begins, the better the chances of a positive outcome for the patient. Delays in diagnosis can result in increased mortality rates and higher healthcare costs.

Can you explain what deep vein thrombosis is and how it relates to pulmonary embolism?

Deep vein thrombosis, or DVT, occurs when a blood clot forms in a deep vein, usually in the leg. Similar to pulmonary embolism, this clot can cause serious problems. While DVT itself can be painful and cause swelling, the most significant risk is that the clot can break loose and travel to the lungs, causing a pulmonary embolism. Therefore, timely diagnosis and treatment of DVT are essential to prevent this life-threatening complication.

What are electronic clinical decision support tools and how can they help with diagnosing pulmonary embolism and deep vein thrombosis?

Electronic clinical decision support, or eCDS, refers to the use of technology to assist healthcare professionals in making clinical decisions. In the context of pulmonary embolism and deep vein thrombosis, eCDS tools can help physicians quickly assess a patient's risk, order appropriate tests, and guide treatment decisions. By integrating clinical guidelines and patient data, eCDS systems aim to improve the accuracy and speed of diagnosis, leading to better patient outcomes. Effective implementation of eCDS requires collaboration and ongoing refinement to ensure it meets the needs of healthcare providers and patients.

What does it mean if someone experiences a delayed diagnosis of pulmonary embolism, and why is this a concern?

A delayed diagnosis of pulmonary embolism means that the condition was not identified during an initial medical encounter, leading to a delay in treatment. This can occur when patients present with non-specific symptoms or when healthcare providers do not immediately suspect PE. Research suggests that delayed PE diagnosis is a common problem, and while one study indicated that delayed diagnosis did not lead to significantly worse outcomes, the importance of improved early detection methods cannot be understated. Addressing this delay is critical for improving patient safety and optimizing healthcare resource utilization.

What is a multi-center retrospective cohort study, and what can we learn from this type of study about pulmonary embolism?

A multi-center retrospective cohort study is a research approach that involves analyzing data collected from multiple healthcare centers over a defined period of time. In the context of PE, such a study might examine patient records from different emergency departments to understand the prevalence of delayed diagnosis, identify risk factors, and evaluate the impact of interventions. By including a large and diverse patient population, these studies provide valuable insights into real-world clinical practice and help inform strategies for improving care. The retrospective nature means researchers look back at already collected data, allowing for efficient analysis of past trends and outcomes.
