Released December 2, 2014

Don’t perform positive airway pressure re-titration studies in asymptomatic, adherent sleep apnea patients with stable weight.

Re-titration of positive airway pressure (PAP) is not indicated for adult obstructive sleep apnea patients with stable weight whose symptoms are well controlled by their current PAP treatment. Follow-up PSG or re-titration is indicated for adult patients who are again symptomatic despite the continued, proper use of PAP, especially if they have gained substantial weight (e.g. 10% of original weight) since the last titration study. A new diagnostic PSG or re-titration may be indicated for patients who have lost substantial weight, to determine whether PAP treatment is still necessary.

How The List Was Created

The Executive Committee of the American Academy of Sleep Medicine developed 21 candidate recommendations for ways in which medical waste could be minimized while care for patients with sleep disorders is improved. Members of the Executive Committee then voted to assign priorities to each, and the top five were selected. Final wording of the five statements were approved by the full Board of Directors of the American Academy of Sleep Medicine. The Secretary/Treasurer and research staff of the American Academy of Sleep Medicine developed rationale and references for each recommendation. The final statements, explanations and citations were approved by a final vote of the Board of Directors.
