About

Obstructive Sleep Apnea (OSA) is seen in approximately 6% of Americans. It is a serious medical condition with significant medical and psychological consequences, including diabetes, hypertension, and cardiovascular disease. The treatment of choice for OSA is Positive Airway Pressure therapy (PAP). PAP supplies positive pressure to the upper airway creating a "pneumatic splint" to keep the airway open during sleep. Adherence to PAP is notoriously low, with as few as 50% reaching minimal guidelines for adherence. One comprehensive review of adherence research found that adherence to PAP was less than that for any other medical disorder. The problem of adherence is significant not only because of the medical consequences that can ensue, but also because third party payers have begun to refuse to pay for PAP therapy when adherence is less than optimal, even in the face of clinical improvement. This is a critical time to address this problem.

This research study is designed to identify methods that may help people respond to PAP, the most common therapy for OSA. Identifying these methods may be an important way to better care for patients with obstructive sleep apnea. With this research, the investigators hope to find ways to help people have a better response to treatment and a better quality of life.

Enrollment: 284 patients

Sex: All

Ages: 21 to 80 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Polysomnography (PSG) confirmed diagnosis of Obstructive Sleep Apnea (OSA)
• choice of PAP as preferred treatment
• judged by sleep physicians to be responders to PAP
• participants will be considered responders to PAP if they have an AHI of less than 5, do not snore, and have an arousal index of less than 10 when titrated to the proper pressure of PAP

Exclusion criteria

• Apnea-Hypopnea Index (AHI) < 15 on the diagnostic PSG and no daytime functional symptoms or associated cardiovascular disease
• a sleep disorder other than OSA that causes arousals from sleep (e.g., periodic limb movements, restless legs syndrome, insomnia)
• a current substance abuse problem
• a serious sleep-disruptive medical condition (e.g., end stage renal failure, severe Chronic Obstructive Pulmonary Disease (COPD), severe asthma)
• significant global cognitive impairment
• history of or current diagnosis of psychosis, bipolar disorder, or borderline, schizotypal or antisocial personality disorder, and uncontrolled depression or suicidal ideation
• change in antidepressant medications over the past 3 months
• women pregnant women, breast feeding, or planning on becoming pregnant
• currently enrolled in another research study

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

284 participants in 3 patient groups, including a placebo group

Brief Personalized Video (BPV)

Experimental group

Description:

Our BPV intervention focuses on augmenting risk perception and reducing optimistic bias by showing the patient a dramatic video of his/her own apnea (which shows them struggle to breathe), as well as by explaining the physiological processes involved in an apneic event. Specific apneic events are highlighted and associated decreases in blood oxygen levels are demonstrated via oxygen saturation recording superimposed on the video. This group will receive educational information about OSA, its consequences and the need for treatment.

Treatment:

Behavioral: Brief Personalized Video (BPV)

Non-Personalized Video (NPV)

Active Comparator group

Description:

NPV will include a video of someone having apnea, but it will not be personalized. This group will receive educational information about OSA, its consequences and the need for treatment.

Treatment:

Behavioral: Non-Personalized Video (NPV)

Treatment As Usual (TAU)

Placebo Comparator group

Description:

The TAU group will receive no special treatment from study interventionist team and will not view a video.

Treatment:

Behavioral: Treatment as Usual (TAU)
