RESUMO

OBJECTIVES: To determine the assessment and inter-rater reliability of echocardiographic evaluations of pulmonary vascular disease (PVD) in preterm infants at risk for bronchopulmonary dysplasia. STUDY DESIGN: We prospectively studied echocardiograms from preterm infants (birthweights 500-1250 g) at 7 days of age and 36 weeks postmenstrual age (PMA). Echocardiograms were assessed by both a cardiologist on clinical service and a single research cardiologist. Interpretations were reviewed for inclusion of determinants of PVD and assessed for inter-rater reliability using the Prevalence Adjusted Bias Adjusted Kappa Score (PABAK). RESULTS: One hundred eighty and 188 matching research and clinical echocardiogram reports were available for the 7-day and 36-week PMA studies. At least one of the specific qualitative measures of PVD was missing from 54% of the clinical reports. PVD was diagnosed at 7 days in 31% and 20% of research and clinical interpretations, respectively (PABAK score of 0.54). At 36 weeks, PH was diagnosed in 15.6% and 17.8% of research and clinical interpretations, respectively (PABAK score of 0.80). CONCLUSIONS: Although all qualitative variables of PVD are not consistently provided in echocardiogram reports, the inter-rater reliability of cardiologists evaluating measures of PVD revealed strong agreement, especially at 36 weeks PMA. We speculate that establishment of a protocol for echocardiographic evaluation may improve the identification of PVD in preterm infants.

RESUMO

BACKGROUND: Human metapneumovirus (HMPV) and respiratory syncytial virus (RSV) are among the leading causes of respiratory tract infections requiring admission to the pediatric intensive care unit (PICU). We evaluated the risk factors, clinical courses and outcomes of severe HMPV disease relative to severe RSV in children admitted to the PICU. METHODS: Retrospective chart review of children ≤18 years old admitted to a tertiary PICU between October 2008 through July 2010 with acute respiratory tract infection and positive direct antigen stain or polymerase chain reaction for RSV or HMPV. RESULTS: One hundred thirty-three patients met inclusion criteria: 107 (80.5%) with RSV and 26 (19.5%) with HMPV. HMPV-infected patients were older than RSV children (3.4 vs. 1.5 years, P = 0.002) and more likely to have congenital heart disease (34.6% vs. 10.3%, P = 0.002). Although HMPV children required longer duration of mechanical ventilation (11 vs. 7 days, P = 0.01), there were no other differences in hospital course. HMPV patients were more likely to be discharged receiving inhaled steroids (53.8% vs. 30.8%, P = 0.03), but there were no differences in other outcome assessments. CONCLUSIONS: Children admitted to the PICU with HMPV are significantly older and more likely to have congenital heart disease than those with RSV. The course of illness was similar between the 2 groups, but HMPV-infected children were more likely to be discharged with inhaled steroid therapy.
