The purpose of this study is to examine the feasibility of a tailored (i.e., individualized) intervention to promote adherence to continuous positive airway pressure therapy (CPAP) in adults with newly-diagnosed, CPAP treated, obstructive sleep apnea.

Condition Intervention Phase
Sleep Apnea, Obstructive Patient Compliance Behavioral: Tailored Other: Usual care Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Phase I Double-blind Randomized Controlled Trial: Sociocultural and Cognitive Perception Intervention to Promote Positive Airway Pressure Adherence

Further study details as provided by Amy M. Sawyer, Milton S. Hershey Medical Center:

Primary Outcome Measures:
  • Nightly CPAP Use [ Time Frame: 1 week ]
    Mean CPAP use, hrs/night

  • Nightly CPAP Use [ Time Frame: 1 month ]
    Mean CPAP use, hrs/night

  • Nightly CPAP Use [ Time Frame: 3 months ]
    Mean CPAP use, hrs/night

Secondary Outcome Measures:
  • Proportion of Sleep Time on CPAP [ Time Frame: 1 week ]
    % of Total Sleep Time (TST) using CPAP

  • Proportion of Participants Who Complete Protocol After Allocation [ Time Frame: Duration of protocol period ]
    Feasibility assessment - retention after enrollment and allocation employed as a feasibility outcome of pilot RCT

  • Proportion of Participants Who Withdrawal [ Time Frame: Duration of protocol period ]
    Feasibility assessment - withdrawal by participants for feasibility outcome of pilot RCT

  • Acceptability of Study Intervention and Comparative Group [ Time Frame: 3 months ]
    Feasibility assessment to determine participant acceptance of the study intervention and comparative condition (i.e., usual care); semi-structured interviews conducted with 50% of participants randomly assigned to "interview" at study termination and debriefing (3 months)

Enrollment: 118
Study Start Date: November 2011
Study Completion Date: March 2014
Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Tailored
Tailored, or individualized, intervention addressing patient education, skills training, and cognitive perceptions
Behavioral: Tailored
Individualized on critical indicator (Self-efficacy measure in Sleep Apnea) measured at each intervention delivery period (pre-diagnosis, immediately post-diagnosis, post-CPAP titration, and during week 1 of home CPAP treatment. Intervention components include patient education, preparatory skills training, modification of inaccurate/unrealistic cognitive perceptions of risk, outcome expectations, and treatment self-efficacy
Other Name: Individualized
Active Comparator: Usual care
The comparison group, usual care, includes the standard of care delivered to all newly-diagnosed OSA persons proceeding to CPAP treatment
Other: Usual care
Usual care comparison group will proceed from initial clinical evaluation for OSA, diagnosis by polysomnography, CPAP titration polysomnography, and home CPAP treatment initiation as per current standard of care
Other Name: standard of care

Detailed Description:
Poor adherence to CPAP is a significant problem among OSA patients resulting in suboptimal health and functional outcomes. Intervention studies to promote CPAP adherence have shown relatively small effects in selected samples and were costly. The overall objective of this research is to examine the effect, feasibility, and acceptability of a tailored intervention on CPAP adherence among adults with newly-diagnosed, CPAP treated OSA. The central hypothesis is that critically timed tailored interventions that focus on sociocultural aspects and cognitive perceptions of the individual experience with OSA diagnosis and treatment will improve overall CPAP adherence rates. The pilot randomized controlled trial will examine CPAP adherence outcomes at 1wk, 1mo, and 3mo among those randomly assigned to the tailored intervention or usual (standard) care and examine specific feasibility and participant acceptability outcomes in order to design and conduct a subsequent larger randomized controlled trial testing the overall efficacy of the tailored intervention.
