Assessing the agreement of chronic lung disease of prematurity diagnosis between radiologists and clinical criteria

Abstract

Abstract Background Chronic lung disease of prematurity (CLD) is the most prevalent complication of preterm birth and indicates an increased likelihood of long-term pulmonary complications. The accurate diagnosis of this condition is critical for long-term health management. Numerous definitions define CLD with different clinical parameters and radiology findings, making diagnosis of the disease ambiguous and potentially inaccurate. Methods 95 patients were identified for this study, as determined by the diagnosis or confirmation of CLD in the impression of the radiologist’s report on chest x-ray. Pulmonary function and complications were recorded at multiple benchmark timeframes within each patient’s first few months of life and used for determining eligibility under each definition. Results Each clinical definition of CLD had a high sensitivity for patients identified to have CLD by radiologists, correctly fitting over 90% of patients. Most patients included required invasive mechanical ventilation or positive pressure ventilation at 36 weeks postmenstrual age, indicating patients with radiographically confirmed CLD tended to have more severe disease. Radiologists tended to diagnose CLD before 36 weeks postmenstrual age, a timepoint used by multiple standard clinical definitions, with cases called earlier fitting under a larger percentage of definitions than those called later. Conclusions Radiologists tend to diagnose CLD in young patients with severe respiratory compromise, and can accurately diagnose the condition before developmental milestones for clinical definitions are met.
