Inter-observer agreement between physicians, nurses, and respiratory therapists for respiratory clinical evaluation in bronchiolitis.
Care providers for children with bronchiolitis use various tools to evaluate respiratory status. The use of a single tool by different types of care provider requires a high level of inter-observer agreement, an aspect rarely studied. This study, involving 82 physicians, nurses, and respiratory therapists aimed to evaluate inter-observer agreement for clinical evaluations in children hospitalized for a first episode of bronchiolitis. ⋯ Inter-observer agreements for the various age groups ranged from 87% to 93%, with kappa scores ranging from 0.62 to 0.78. We conclude that a simple clinical evaluation for respiratory status assessment has a high level of inter-observer agreement within and between physicians, nurses and respiratory therapists. Thus, once the validity of this test has been confirmed in a large population sample, it should be possible to use this test to monitor children hospitalized with bronchiolitis and as an endpoint in clinical trials.

Using index of ventilation to assess response to treatment for acute pulmonary exacerbation in children with cystic fibrosis.
The use of alternative more sensitive measures has become a focus of research in CF. The utility of indexes of ventilation, Lung Clearance Index (LCI) and peak aerobic capacity (peak VO(2)), were studied as assessment tools in gauging response to intravenous (IV) therapy in acute pulmonary exacerbation, in comparison to the more commonly used index of forced expiratory volume in 1 sec (FEV(1)). The utility of a previously published clinical score was further explored. ⋯ In children with mild-to-moderate CF, whilst statistically significant improvement in both LCI and peak VO(2) were seen, heterogeneity of response was evident. The most consistent improvement was seen in CFCS. Correlation of LCI and peak VO(2) with change in clinical score (CFCS) was seen. The full clinical significance of these changes in LCI and peak VO(2) needs to be evaluated further with additional variability data. The CFCS may be useful in the assessment of response to treatment in CF but requires formal validation.
