Rating Scheme for the Strength of the Recommendations

Table of Recommendation Strength

Strength Definition
"Strongly recommended" There is consensus that benefits clearly outweigh risks and burdens (or vice-versa for negative recommendations).
"Recommended" There is consensus that benefits are closely balanced with risks and burdens.
No recommendation made There is lack of consensus to direct development of a recommendation.
Dimensions: In determining the strength of a recommendation, the development group makes a considered judgment in a consensus process that incorporates critically appraised evidence, clinical experience, and other dimensions as listed below.
  1. Grade of the Body of Evidence (see note above)
  2. Safety/Harm
  3. Health benefit to the patients (direct benefit)
  4. Burden to patient of adherence to recommendation (cost, hassle, discomfort, pain, motivation, ability to adhere, time)
  5. Cost-effectiveness to healthcare system (balance of cost/savings of resources, staff time, and supplies based on published studies or onsite analysis)
  6. Directness (the extent to which the body of evidence directly answers the clinical question [population/problem, intervention, comparison, outcome])
  7. Impact on morbidity/mortality or quality of life
Cost Analysis

A formal cost analysis was not performed and published cost analyses were not reviewed.

Method of Guideline Validation
Peer Review
Description of Method of Guideline Validation

Reviewed against quality criteria by 2 independent reviewers.

Recommendations

Major Recommendations

There is insufficient evidence and a lack of consensus to make an audiologic recommendation for atresiaplasty versus the Baha system.

Research Agenda

It is recommended that data collection among children who have had atresiaplasties and children who have had Baha surgery be done to provide more information about options for children with aural atresia.

Clinical Algorithm(s)

None provided

Evidence Supporting the Recommendations

Type of Evidence Supporting the Recommendations

Current evidence was found to be mostly expert opinion or descriptive studies, which was considered insufficient to make a recommendation.

Benefits/Harms of Implementing the Guideline Recommendations

Potential Benefits

Some improved access to hearing has been found with both atresiaplasty and Baha, but low level evidence shows better hearing outcome with Baha.

Potential Harms

Atresiaplasty may not result in an ear canal that can retain a hearing aid or earmold. Repeat surgery/revision may be necessary to achieve optimal results with both atresiaplasty and Baha. Anesthesia risks and risk of infection must be considered when surgery is involved. This is true for both atresiaplasty and Baha.

Qualifying Statements

Qualifying Statements

This Best Evidence Statement addresses only key points of care for the target population; it is not intended to be a comprehensive practice guideline. These recommendations result from review of literature and practices current at the time of their formulation. This Best Evidence Statement does not preclude using care modalities proven efficacious in studies published subsequent to the current revision of this document. This document is not intended to impose standards of care preventing selective variances from the recommendations to meet the specific and unique requirements of individual patients. Adherence to this Statement is voluntary. The clinician in light of the individual circumstances presented by the patient must make the ultimate judgment regarding the priority of any specific procedure.
