New 'Diagnostics in a Box' could speed up breathlessness diagnosis
NCT ID NCT07320703
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a tool called 'Breathlessness diagnostics in a Box' (BiaB) to see if it helps doctors in primary care diagnose the cause of breathlessness faster than usual care. About 900 adults in the Netherlands, Spain, and Portugal will take part. The tool is used during routine visits to guide testing and diagnosis.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
The study aims to capture the real-world heterogeneity in primary care practices and patients. Therefore, inclusion and exclusion criteria are limited. Inclusion criteria * Patient must be at least 18 years old at the time of signing the informed consent. * Patients that present with undiagnosed dyspnea (breathlessness); or Patients who have existing diseases that could cause breathlessness, but have residual or increasing breathlessness that could be caused by other not yet detected diseases. Or HCP has doubts or requires additional tests to confirm diagnosis or to suspect new, parallel, diagnoses. For example, breathlessness in patients assessed within the framework of Cardiovascular Risk Management or for COPD monitoring Exclusion criteria 1. Acute worsening of previous diagnosed chronic disease where there is no suspicion of comorbidities (for example when a patient with clear COPD diagnosis has an exacerbation where typically the HCP will not perform additional tests). 2. Inability to understand and sign the written consent form.
