Respiratory failure & ventilation
Agreement between chest radiograph and computed tomography for the diagnosis of acute respiratory distress syndrome: A retrospective observational study
Authors' conclusion
Chest radiograph has limited performance for the diagnosis of ARDS, and at least 20% of patients with ARDS on chest CT were not diagnosed using chest radiograph.
Study context
- Population
- Hypoxemic intubated patients meeting all but the imaging criterion for acute respiratory distress syndrome (ARDS) (Berlin criteria) with chest computed tomography (CT) and chest radiograph the same day, over a 7-year period
- Participants
- 277 participants
- Exposure
- Chest radiograph vs chest CT for diagnosis of ARDS
- Outcome
- Agreement between chest radiograph and chest CT for diagnosis of ARDS in the overall population (Cohen's kappa)
Methodological detailssingle-centre, diagnostic agreement
- Single-centre
- Diagnostic agreement
Main finding
As reported in the abstract
Agreement between chest radiograph and chest CT for ARDS
- Agreement fair to moderate overall and consistent across subgroups
Observational data: associations, not effects.
