Objective: Clinical practice guidelines synthesize and disseminate the best available evidence to guide clinical decisions and increase high-quality care. Since 2004, the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) has published 16 guidelines. The objective of this review was to evaluate clinicians' adherence to these guidelines' recommendations as measured in the literature.
Data sources: We searched PubMed, Embase, and Web of Science on August 29, 2019, for studies published after June 1, 2004.
Review methods: We systematically identified peer-reviewed studies in English that reported clinician adherence to AAO-HNSF guideline recommendations. Two authors independently reviewed and abstracted study characteristics, including publication date, population, sample size, guideline adherence, and risk of bias.
Results: The search yielded 385 studies. We excluded 331 studies during title/abstract screening and 32 more after full-text review. The remaining 22 studies evaluated recommendations from 8 of the 16 guidelines. The Otitis Media with Effusion, Polysomnography, Tonsillectomy, and Sinusitis guidelines were studied most. Study designs included retrospective chart reviews (7, 32%), clinician surveys (7, 32%), and health care database analyses (8, 36%). Studies reported adherence ranging from 0% to 99.8% with a mean of 56%. Adherence varied depending on the recommendation evaluated, type of recommendation, clinician type, and clinical setting. Adherence to the polysomnography recommendations was low (8%-65.3%). Adherence was higher for the otitis media with effusion (76%-90%) and tonsillectomy (43%-98.9%) recommendations.
Conclusions: Adherence to recommendations in the AAO-HNSF guidelines varies widely. These findings highlight areas for further guideline dissemination, research about guideline adoption, and quality improvement.
