Overview
The Respiratory distress assessment instrument (RDAI) is an assessment scale to evaluate the severity of illness in infants.
Historical Perspective
The RDAI was developed in 1987 to measure response to treatment of bronchiolitis.[1]
Data Source for Derivation and Validation
The RDAI was tested for reliability by two of the original investigators. They reported weighted kappa of 0.9.[1]
Usage and Application of the Instrument
Recently, the construct validity of the RDAI has been challenged due to low correlation with subsequent admission to the hospital or length of stay (LOS).[2] In a study of 65 children, the intraclass correlation coefficient was 0.39 (95% CI: 0.17–0.58 [n = 65]) as measured by respiratory therapists.[2] This suggests 'poor' agreement.[3] The Children's Hospital of Wisconsin Respiratory Score (CHWRS) may better predict the need for admission.[2]
