The 20-page multi-society comment letter emphasized that the AHRQ conclusion that there are no significant benefits from CPAP treatment does not reflect the totality of available evidence. Therefore, misinterpretation of the draft report, as currently written, will have detrimental repercussions for the care of millions of Americans with OSA receiving benefit from CPAP therapy now and in the future. The letter provides specific recommendations to address these concerns and asks AHRQ to consider revising the draft report prior to final publication to avoid misinterpretations or the appearance of bias.
The comment letter addresses the following concerns:
- Excessive sleepiness was not considered a clinically important, patient-centered, long-term outcome.
- Important data on motor vehicle crashes was not considered.
- Improvement in blood pressure was not considered a clinically relevant outcome.
- Analyses of the apnea-hypopnea index (AHI) as an intermediate outcome had potential limitations.
- The future research section did not adequately consider the barriers to conducting randomized controlled trials (RCTs).
- The summary statements were unclear.
AHRQ stated that the report is intended to help health care decision makers make well-informed decisions that improve the quality of health care services. However, AHRQ also noted that the report is not intended to be a substitute for the application of clinical judgment.
