Lung perfusion scans in ED patients with suspected pulmonary embolism

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a single-center, retrospective observational study using routinely collected electronic health records from Antalya Training and Research Hospital. The researchers will identify adults evaluated for suspected pulmonary embolism who underwent pulmonary perfusion scintigraphy, with or without ventilation scintigraphy, from January 1, 2019 to the ethics approval date. They will review how scan results correlated with decisions such as starting or stopping anticoagulation, requesting additional imaging, and hospital disposition, as well as patient flow metrics like ED and hospital length of stay, ICU admission, return ED visits, and 30-day mortality. Imaging findings will be categorized by the original nuclear medicine reports and management changes will be assessed from documented diagnostic assessments, anticoagulation decisions, and disposition notes. All data are from routine clinical care and no experimental interventions are performed.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Age 18 years or older at the index emergency department visit.
* Evaluation for suspected pulmonary embolism at Antalya Training and Research Hospital during the study period.
* Completion of pulmonary perfusion scintigraphy, with or without additional ventilation scintigraphy, for suspected pulmonary embolism.
* Availability of medical records containing the demographic, clinical, imaging, and outcome information required for the study.

Exclusion Criteria:

* Scintigraphy performed for an indication other than suspected pulmonary embolism.
* Scintigraphy requested by a department other than the emergency department.
* Scintigraphy requested but not completed.
* Unavailable scintigraphy reports or essential clinical records.
* Unavailable essential outcome information, including emergency department disposition, hospitalization, intensive care admission, or mortality status.
* Duplicate records relating to the same clinical episode. Separate episodes involving a new evaluation for suspected pulmonary embolism may be included as distinct clinical episodes.
