The MedCAC met on September 12, 2007, to discuss the evidence, hear presentations and pubic comment, and make recommendations regarding the diagnosis and treatment of obstructive sleep apnea (OSA) in Medicare beneficiaries who may be candidates for continuous positive airway pressure (CPAP) therapy, and alternatives to facility-based polysomnography in the diagnosis of OSA, including home sleep testing devices and clinical diagnosis without the use of sleep testing.
The meeting began with a reading of conflict of interest issues, opening remarks by the vice chair and CMS liaison, and introduction of the Committee.
CMS Summary and Presentation of Voting Questions. A CMS representative presented the discussion and voting questions to be considered by the panel.
Presentation on behalf of Requestor. The panel heard from a representative of the American Academy of Otolaryngology - Head and Neck Surgery supporting broadening the application and use of in-home sleep monitoring.
Presentation of the Technology Assessment. The results of a technology assessment performed by the Tufts new England Medical Center Evidence-Based Practice Center were presented.
Other Presentations. The panel heard presentations from a member of the CMS staff, and a Canadian researchers.
Scheduled Public Comments. Fifteen speakers, including professional society representatives, manufacturers' representatives, clinicians and other healthcare professionals, addressed the panel.
Open Public Comments. Following the scheduled public comments, the panel heard from four additional speakers.
Questions to Presenters. The panel conducted an extensive question and answer period with the various presenters and other speakers.
Initial Open Panel Discussion. There was an extensive period of discussion surrounding the initial discussion questions, as well as the form of the voting questions and definitions to be applied during the deliberations and voting.
Formal Remarks and Voting. The panel voted on the following questions.
One. How confident are you that there is sufficient evidence to determine that each of the following strategies can in routine use produce an accurate diagnosis of OSA for the prescription of CPAP?
Two. For each OSA diagnostic strategy for which there is enough evidence in question one, how confident are you about the sensitivity, ability to minimize false negatives, and specificity, ability to minimize false positives?
Three. Should each of the following be weighed as a criterion for the prescription of CPAP for the diagnosis of OSA?
Four. CPAP is currently a standard treatment for OSA. Defining successful treatment as combined subjective improvement of OSA clinical signs or symptoms and continued patient use of CPAP for two or more months, how confident are you that there is sufficient evidence to determine the ability of each of the following diagnostic strategies to accurately predict successful treatment of OSA with CPAP?
Five. How confident are you that each of the following diagnostic strategies will accurately predict successful treatment of OSA with CPAP?
Six. How confident are you that no clinically meaningful harm to patients will be caused by a trial CPAP strategy as an alternative to strategies that require a positive prior PSG or home sleep test before CPAP?
Seven. How confident are you that your conclusions can be generalized to, A, the Medicare population, and B, providers in community practice?
The results of the voting were recorded on individual tally sheets and compiled by staff. During the voting procedure, further discussion was held among the panelists concerning each question voted upon, and individual comments were made by panelists during each vote, amplifying their reasons for voting as they did.
