SleepWell24: An Innovative Smartphone Application to Improve PAP Adherence

Obstructive sleep apnea (OSA) is a major public health concern n the United States. Positive airway pressure (PAP) therapy is the treatment-of-choice and "gold standard" for individuals with moderate-to-severe OSA. Regular and sustained PAP use can reduce risk for subsequent disease and improve quality of life. Nevertheless, PAP adherence rates are low. Most PAP adherence programs do not address the self-management skills and strategies that promote adherence and are often too costly and complex to integrate into overburdened clinical environments. Furthermore, they do not leverage opportunities to change lifestyle behaviors that occur across the 24h spectrum (i.e., sleep hygiene, sedentary behavior, physical activity), which have promise to improve OSA symptoms and PAP adherence. The investigators have previously developed and successfully tested BeWell24, a multicomponent smartphone "app" that uses evidence-based behavior change strategies to improve sleep, sedentary, and physical activity behaviors. The investigators will enhance this app to create SleepWell24. Enhancements will include: (1) specific behavior change strategies from the evidence-based Sleep Apnea Self-Management Program to promote PAP adherence; (2) an interface for exchange of patient data to facilitate patient-provider communication on treatment progress; and (3) real-time feedback via wireless integration with a consumer-based PAP machine and wearable sensor. All aspects of this work will be embedded within the Mayo Clinic Arizona Center for Sleep Medicine. The investigators will test the effects of SleepWell24 in newly prescribed PAP users and gather data on the feasibility and acceptability of using SleepWell24 compared to a usual care control group. The investigators will conduct a pilot randomized controlled trial with participants randomly assigned to (1) SleepWell24; or (2) usual care for 60 days post-PAP prescription. The investigators will track recruitment/retention rates, app usage statistics, and measures of treatment satisfaction. The investigators will objectively measure PAP adherence to test whether the SleepWell24 group will have more hours/night of PAP usage compared to the usual care group. In an exploratory fashion, the investigators will also examine the effect of SleepWell24 on selected treatment outcomes (weight, daytime sleepiness, cognitive impairment, and health-related quality of life) and evaluate social cognitive and lifestyle behavior mediators of SleepWell24 on PAP adherence.

Study Overview

• Status: Completed
• Conditions: Obstructive Sleep Apnea of Adult
• Intervention / Treatment: Behavioral: SleepWell24 Application; Other: Usual Care Plus Activity Monitor

Detailed Description

This exploratory study will test the feasibility and initial efficacy of a mobile health smartphone intervention to increase adherence to positive airway pressure (PAP) therapy in newly diagnosed obstructive sleep apnea (OSA) patients treated at the Mayo Clinic Arizona Center for Sleep Medicine and associated outpatient clinics. This app, called SleepWell24, will include PAP adherence behavior change strategies (drawn from the evidence-based Sleep Apnea Self-Management Program), cloud-based linkages to a consumer-based PAP machine and wearable sensor that provides nightly feedback on PAP adherence and sleep and activity metrics, and a component to enhance patient-provider communication. The investigators will embed SleepWell24 within usual patient care at the Mayo Clinic Arizona Center for Sleep Medicine and associated outpatient clinics for app design/development, patient recruitment, and treatment feasibility/satisfaction. This design will ensure the best opportunity for clinical adoption. The primary aims are:

Aim 1: Determine the feasibility and acceptability of SleepWell24 from patient and provider perspectives.

Aim 2: Determine the extent to which SleepWell24 improves PAP adherence over the first 60 days of use relative to usual care.

As an exploratory aim the investigators will explore the effect of SleepWell24 on treatment outcomes (weight, daytime sleepiness, cognitive performance, health-related quality of life) and putative social cognitive and behavioral mediators of PAP adherence (e.g., self-efficacy, sleep quality, sedentary behavior, physical activity).

The investigators will test the feasibility, acceptability, initial efficacy and outcomes of SleepWell24 compared to usual care during the first 60 days of PAP use among 94 patients newly diagnosed with obstructive sleep apnea.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: SleepWell24 Application; A mobile health smartphone application based on evidence-based health behavior change theory and interventions to promote adherence to positive airway pressure therapy	Behavioral: SleepWell24 Application; An evidence-based behavioral change smartphone application designed to promote adherence to positive airway pressure (PAP) therapy
Other: Usual Care Plus Activity Monitor; Per usual clinical care standards within the Center for Sleep Medicine at Mayo Clinic Arizona, all patients will receive instructions/education on positive airway pressure (PAP) use, multiple mask fittings, encouragement to use PAP every night, and staff is available in the event of problems. Control patients will also receive a wearable activity monitor to use during the study. The wearable sensor will be used to isolate the effect of SleepWell24 on PAP adherence from potential novelty effects due to receiving a generic health behavior change app.	Other: Usual Care Plus Activity Monitor; Participants will receive usual care at the Mayo Clinic Center for Sleep Medicine when first diagnosed with sleep apnea and prescribed positive airway pressure therapy. In addition, they will receive a commercial activity monitor with an associated smartphone application to isolate the effect of SleepWell24 on PAP adherence from potential novelty effects due to receiving a generic health behavior change app.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Recruitment and Retention	numbers recruited and retained over the course of the trial	Duration of the trial (~60 days)
SleepWell24 application usage	objective metrics of smartphone application usage by intervention group	Duration of the trial (~60 days)
Treatment acceptability/satisfaction	Intervention acceptability questionnaire for both groups	Baseline vs. Day 60 of trial
Positive airway pressure therapy use	How many hours per night therapy was used throughout the trial	Duration of the trial (~60 days)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Body Mass Index	body mass index according to weight and height	Baseline and follow-up visit between days 31 and 60
Daytime Sleepiness	Epworth Sleepiness Scale	Baseline, Day 30, Day 60 of trial
Cognitive functioning	Neurocognitive battery	Baseline and follow-up visit between days 31 and 60
Global Quality of Life due to physical and mental health via the Patient Reported Outcomes Measurement Information System Global Health Scale	The investigators will measure quality of life in general as informed by current physical and mental health using the quality of life in general as informed by current physical and mental health using the Patient Reported Outcomes Measurement Information System Global Health Scale. This Scale measures an individual's physical, mental, and social health, in general. This measure produces 2 scores: Physical Health and Mental Health. Summed raw scores are converted to T-score values with a mean of 50 and a standard deviation of 10. A higher T score indicates better Global Physical or Mental Health depending on the subscale used.	Baseline, Day 30, Day 60 of trial
Sleep Apnea-Specific Quality of Life	The investigators will measure functional outcomes of sleep apnea with the Functional Outcomes of Sleep Questionnaire, which measures how difficult it is to carry out certain activities because of daytime sleepiness due to sleep apnea. It is a 10-item questionnaire representing 5 subscales. To obtain the total score, a mean-weighted item score is first computed for subscales with more than one item. Then the total score is derived by calculating the mean of the subscale scores and multiplying that mean by 5. Higher total scores indicate less difficulty with sleepiness due to sleep apnea affecting daytime activities. Scale ranges from 0 to 40.	Baseline, Day 30, Day 60 of trial
