Frequency of Sleep Studies for Patients with Sleep Apnea

Indications for Follow-up Sleep Studies

The American Academy of Sleep Medicine recommends follow-up sleep studies for patients with sleep apnea when there are changes in symptoms or treatment efficacy, not on a routine yearly basis 1
Follow-up polysomnography (PSG) or attended cardiorespiratory sleep studies are indicated after substantial weight changes, such as a 10% change in body weight, with return of symptoms 1
The American Academy of Sleep Medicine indicates follow-up testing when clinical response to treatment is insufficient or symptoms return despite a good initial response to treatment 1
Follow-up PSG or attended cardiorespiratory sleep study is routinely indicated for assessment of treatment results after surgical treatment for moderate to severe OSA 1
The American Academy of Sleep Medicine and Pulmonology recommend follow-up PSG or attended cardiorespiratory sleep study with the oral appliance in place after final adjustments of fit have been performed to ensure satisfactory therapeutic benefit from oral appliances 1, 2

The American Academy of Sleep Medicine states that follow-up PSG is not routinely indicated in patients treated with CPAP whose symptoms continue to be resolved with treatment 1
PSG should be performed if symptoms return or worsen despite continued CPAP use, as recommended by the American Academy of Sleep Medicine 1

The American Academy of Sleep Medicine and Pulmonology recommend follow-up sleep study after final adjustments to ensure therapeutic benefit from oral appliances 1, 2
Pulmonology suggests a follow-up protocol after final calibration, including patient evaluation every six months for the first year and at least annually thereafter 2

The American Academy of Sleep Medicine indicates that follow-up PSG or attended cardiorespiratory sleep study is routinely indicated after surgical treatment for moderate to severe OSA 1
Additional follow-up is needed if symptoms return despite initial good response, as recommended by the American Academy of Sleep Medicine 1

Significant weight changes, such as gain or loss, can alter the severity of sleep apnea and necessitate reassessment, according to the American Academy of Sleep Medicine 1
Development of new comorbidities, such as heart failure or stroke, may require reassessment of sleep apnea severity and treatment, as recommended by the American Academy of Sleep Medicine 1

The American Academy of Sleep Medicine states that there is no evidence supporting routine annual sleep studies for all sleep apnea patients 1
Significant weight changes should trigger reassessment of sleep apnea severity and treatment efficacy, as recommended by the American Academy of Sleep Medicine 1
