Videofluoroscopy compared with clinical feeding evaluation in children with suspected aspiration.

AIM: Videofluoroscopy swallow studies (VFSS) are gold standard to diagnose aspiration in children but require resources and radiation compared with clinical feeding evaluation (CFE). We evaluated their added value for diagnosis, feeding management and clinical status. METHODS: A retrospective single-centre cross-sectional study of children aged 0-18 years, with respiratory morbidity, referred for VFSS at a tertiary pediatric hospital. RESULTS: A total of 113 children, median age (range) 2.2 years (0.1-17.9), underwent VFSS. Diagnosis included chronic pulmonary aspiration (CPA), 87 (77%); neurological, 73 (64%); gastrointestinal, 73 (64%) and congenital heart disease, 42 (37%), not mutually exclusive. Forty-six (41%) aspirated, 9 (8%) only overtly and 37 (33%) including silent aspirations. Those with CPA or cerebral palsy were more likely to have VFSS aspiration, OR 3.2 and 9.8 respectively. Feeding recommendations after VFSS differed significantly from those based on prior CFE, p < 0.001: The rate of exclusively orally fed children rose from 65% to 79%, p = 0.006; exclusively enterally fed children from 10% to 14%; p = 0.005. During the year after VFSS, there were significantly less antibiotic courses, total and respiratory admissions. CONCLUSION: In this population with high prevalence of clinically suspected CPA, VFSS altered feeding management compared with CFE and may have contributed to subsequent clinical improvement.

Modified Tal Score: Validated score for prediction of bronchiolitis severity.

OBJECTIVE: To further validate the use of the Modified Tal Score (MTS), a clinical tool for assessing bronchiolitis severity, by physicians with varying experience and training levels, and to determine the ability of the MTS to predict bronchiolitis severity. METHODS: This prospective cohort study included infants of <12 months of age who were diagnosed with bronchiolitis and assessed via MTS. We calculated the intra-class correlation coefficient (ICC) among four groups of raters: group 1, board-certified pediatric pulmonologists; group 2, board-certified pediatricians; group 3, senior pediatric residents; and group 4, junior pediatric residents. Clinical outcomes were determined as length of oxygen support and length of stay (LOS). We assessed MTS's prediction of these outcomes. Relative risk (RR) for clinical severity was calculated via a Generalized Linear Model. RESULTS: Twenty-four physicians recorded a total of 600 scores for 50 infants (average age 5 ± 3 months; 56% male). The ICC values with group 1 as a reference were 0.92, 0.87, and 0.83, for groups 2, 3, and 4, respectively (P < 0.001). RR for oxygen support required was; 1.33 (CI 1.12-1.57), 1.26 (1.1-1.46), 1.26 (1.06-1.5), and 1.21 (0.93-1.58) for groups 1, 2, 3, and 4, respectively. RR for LOS was; 1.15 (CI 0.97-1.37), 1.19 (1.03-1.38), 1.18 (1.0-1.39), and 1.18 (0.93-1.51) for groups 1, 2, 3, and 4, respectively. CONCLUSION: The MTS is a simple and valid scoring system for evaluating infants with acute bronchiolitis, among different physician groups. The first score upon admission is a fair predictor of oxygen requirement at 48 h, and LOS at 72 h.
