An analysis of the literature addressing tonsillectomy knowledge gaps

Area of Science:

• Otolaryngology
• Pediatric Surgery
• Evidence-Based Medicine

Background:

• Clinical practice guidelines are crucial for improving patient outcomes.
• Gaps in evidence for pediatric tonsillectomy were previously identified by guideline authors.
• The quality of evidence underpins the effectiveness of clinical practice guidelines.

Purpose of the Study:

• To evaluate the extent to which new research addresses evidence gaps in the AAO-HNS Tonsillectomy in Children Guideline.
• To assess the impact of recent studies on pediatric tonsillectomy recommendations.

Main Methods:

• PICO (Participants, Intervention, Comparator, Outcome) questions and search strings were developed for each guideline recommendation.
• PubMed was searched for studies published after the AAO-HNS guideline's final literature search.
• Extracted studies were analyzed to determine relevance to guideline recommendations.

Main Results:

• Of 2519 studies reviewed, 276 (11%) were relevant to the 18 recommendations in the Tonsillectomy in Pediatric Patients guideline.
• All but one recommendation had at least one new study addressing it.
• The majority of identified evidence gaps appear to have been addressed by subsequent research.

Conclusions:

• New research has largely addressed the knowledge gaps present in the AAO-HNS Tonsillectomy in Children Guideline at the time of its publication.
• The findings suggest that an updated guideline for pediatric tonsillectomy may be warranted.
• This research is relevant for otolaryngology researchers focusing on evidence-poor areas.
