Poor agreement on radiological tension features
Exploring Inter‐Rater Agreement in Classification of Radiological Features of Tension in Adults With Primary Spontaneous Pneumothorax
Emergency Medicine Australasia · Added 27 July 2026
Interpretation for radiological tension features had poor inter‐rater reliability, which seriously changes their appropriateness as drivers for interventional management.
- Study type
- Cross-sectional
- Design
- Blinded observational inter-rater agreement study
- Participants
- Five emergency physicians reviewing 80 PSP chest x-rays
- Main finding
- Inter-rater agreement for radiological tension features was Krippendorff's Alpha 0.524 (95% CI 0.400–0.623), indicating poor agreement
- Caveat
- Small number of x-rays and reviewers; in-hospital ED setting
- Bottom line
- Hypothesis-generating
Learning goal
Weigh the reliability of chest x-ray tension features when deciding whether to decompress a pneumothorax.

One dose dexamethasone enough for paediatric asthma
Nearly two-thirds of children with asthma exacerbations were treated with 2 doses of dexamethasone rather than a single dose, even though treatment with 2 doses was not associated with improved outcomes.
