Insights
Reliability and validity of infant bronchiolitis assessment tools are poorly established. Further research is needed to develop and validate reliable tools for assessing infants with bronchiolitis.
Area of Science:
- Pediatrics
- Clinical Assessment
- Respiratory Medicine
Background:
- Bronchiolitis is a primary cause of infant hospitalization.
- Existing assessment tools for bronchiolitis are often used in clinical trials.
- The psychometric properties of many bronchiolitis assessment tools are not well-documented.
Purpose of the Study:
- To evaluate the psychometric properties of tools designed for assessing infants with bronchiolitis.
- To determine the reliability and validity of existing bronchiolitis assessment instruments.
Main Methods:
- Systematic review of studies published between 1960 and 2015.
- Searched CINAHL, MEDLINE, EMBASE, and PubMed databases.
- Utilized the COSMIN checklist to assess psychometric properties.
Main Results:
- Reviewed 14 studies assessing 11 different instruments.
- Found that the reliability and validity of most bronchiolitis assessment tools are poorly established.
- The Respiratory Distress Assessment Index showed the most rigorous testing but had moderate construct validity and test-retest error.
Conclusions:
- Current tools for assessing infants with bronchiolitis lack established reliability and validity.
- These tools may not be sensitive to clinically significant patient outcomes.
- There is a need for improved and validated assessment tools in pediatric bronchiolitis.
Aim:
The aim of this study was to assess the psychometric properties of tools developed for the purpose of assessing infants with bronchiolitis.
Background:
Bronchiolitis is the leading cause of hospitalization in infants under the age of 1 year. Several bronchiolitis assessment tools have been developed primarily for use in randomized control trials of medical treatments for infants with bronchiolitis, however, the reliability and validity of many of these tools is not well reported.
Design:
Systematic review.
Data Sources:
CINAHL, MEDLINE, EMBASE and PubMed electronic databases were searched between January 1960-December 2015 using the key words 'bronchiolitis' and 'assessment' or 'screen' or 'tool' or 'scale' or 'score'.
Review Methods:
A systematic review of the psychometric properties of bronchiolitis assessment tools was undertaken using the COSMIN checklist.
Results:
Fourteen studies meeting the inclusion criteria were reviewed and the methodological quality of the studies and reported psychometric properties of 11 instruments were assessed. Overall, the reliability and validity of bronchiolitis assessment tools was poorly established. Although several studies reported that their tools had good inter-rater reliability, the methodological quality of these studies was generally poor. Only one study underwent psychometric testing that was assessed as being of excellent quality. The Respiratory Distress Assessment Index was deemed to have undergone the most rigorous psychometric testing but had poor to moderate construct validity and considerable test-retest error.
Conclusion:
Current bronchiolitis assessment tools lack clearly established reliability and validity and may not be sensitive to clinically meaningful outcomes for patients.
