Reaching for Equity in Sleep Apnea Treatment (REST): Pilot of Telephonic Health Coaching Intervention to Improve Adherence to Sleep Apnea Treatment

This study will test a brief telephonic health coaching intervention to improve adherence to positive airway pressure therapy for treatment of obstructive sleep apnea.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The investigators will carry out a pilot study in which patients will be randomly assigned to receive health coaching or usual care. Participants are English- and Spanish-speaking patients from a county-based public health system who have received a positive airway pressure device for the treatment of sleep apnea. An unlicensed, trained health coach will call patients three times to resolve barriers to adherence. Primary outcomes include both adherence measures collected by the device modem at baseline and 4 months, and patient-reported outcomes such as daytime sleepiness.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Health coaching arm
For the health coaching arm, an unlicensed, trained health coach will call patients up to five times to identify and resolve barriers to adherence, including lack of understanding of their condition or the treatment, discomfort in acclimating to treatment, technical difficulties in mask fit or device settings, and challenges in navigating durable medical equipment providers.
Behavioral: Health coaching
Brief telephonic intervention consisting of up to five phone calls from a health coach
No Intervention: Usual care
Patients assigned to usual care have access to all other available resources, including technical support from durable medical equipment providers, respiratory therapist visits with the Sleep Clinic, group visits, or visits with their primary care provider.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean number of hours used on average over the last 30 days
Time Frame: Enrollment to 4 months post enrollment
Total number of hours PAP device used during 30 day period divided by 30 days (PAP device is part of existing clinical care)
Enrollment to 4 months post enrollment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Proportion using device at any time in last 30 days
Time Frame: Enrollment to 4 months post enrollment
Numerator: Number of people using PAP device at any time in last 30 days; Denominator: Number of people in study arm (PAP device is part of existing clinical care)
Enrollment to 4 months post enrollment
Patient-reported daytime sleepiness

Mean score on the Epworth Sleepiness Scale (8 items with aggregate scale of 0-24 points, where 24 indicates greatest sleepiness symptoms)
Enrollment to 4 months post enrollment
Attitudes to PAP treatment

Mean score on the Attitudes to PAP Treatment Inventory (5 items with combined scale of 4-25, where higher scores indicate negative attitudes toward PAP treatment)
Enrollment to 4 months post enrollment
Confidence in using PAP therapy
