Abstract

BACKGROUND AND OBJECTIVES:

Guideline recommendations for the same clinical condition may vary. The purpose of this study was to determine the degree of agreement among comparable asthma and bronchiolitis treatment recommendations from guidelines.

METHODS:

National and international guidelines were searched by using guideline databases (eg, National Guidelines Clearinghouse: December 16-17, 2014, and January 9, 2015). Guideline recommendations were categorized as (1) recommend, (2) optionally recommend, (3) abstain from recommending, (4) recommend against a treatment, and (5) not addressed by the guideline. The degree of agreement between recommendations was evaluated by using an unweighted and weighted κ score. Pairwise comparisons of the guidelines were evaluated similarly.

RESULTS:

There were 7 guidelines for asthma and 4 guidelines for bronchiolitis. For asthma, there were 166 recommendation topics, with 69 recommendation topics given in ≥2 guidelines. For bronchiolitis, there were 46 recommendation topics, with 21 recommendation topics provided in ≥2 guidelines. The overall κ for asthma was 0.03, both unweighted (95% confidence interval [CI]: -0.01 to 0.07) and weighted (95% CI: -0.01 to 0.10); for bronchiolitis, it was 0.32 unweighted (95% CI: 0.16 to 0.52) and 0.15 weighted (95% CI: -0.01 to 0.5).

CONCLUSIONS:

Less agreement was found in national and international guidelines for asthma than for bronchiolitis. Additional studies are needed to determine if differences are based on patient preferences and values and economic considerations or if other recommendation-level, guideline-level, and condition-level factors are driving these differences.
