Popis: BACKGROUND: Over the past two decades, studies have demonstrated that lung ultrasound is useful in diagnosing alveolar interstitial syndrome, which is seen in patients with decompensated congestive heart failure (CHF). METHODS: We studied medical students performing lung ultrasound on patients admitted to the hospital with a presumed diagnosis of decompensated CHF in a prospective convenience observation study. Two ultrasound fellowship–trained emergency medicine attendings independently reviewed the lung ultrasounds at a later date, blinded to the students’ interpretation and other clinical information, to confirm ultrasound findings and assess for inter‐rater reliability of the lung ultrasound using intraclass correlation coefficients (ICCs). RESULTS: Thirty‐six patients were enrolled in the study resulting in 653 unique lung zones scanned. The zones were imaged and classified as being normal (B‐lines < 3) or pathologic (B‐lines ≥ 3). The novice scanners’ interpretation was compared to expert reviews using ICCs. The ICC was 0.88, with a 95% confidence interval of 0.87 to 0.90, for all lung zones scanned. CONCLUSION: There was almost perfect agreement between novice practitioners and experts when determining the presence of pathologic B‐lines in individual patients.
