Assessment of the Effect of PAP on Energy and Vitality in Mild OSA Patients: The Merge Study

January 6, 2021 updated by: ResMed

Assessment of the Effect of Positive Airway Pressure on Energy and Vitality in Mild Obstructive Sleep Apnea Patients: The Merge Study

The investigators wish to prospectively determine the response to CPAP in patients presenting with mild OSA. In many healthcare systems, patients with mild OSA (AHI 5-15) are not reimbursed for treatment. Although some evidence exists of the benefits of treating mild OSA when scoring as per AASM 2007 criteria, more evidence is needed. The investigators wish to add to this pool of knowledge and also increase the inclusion criteria to include the AASM 2012 definition of mild OSA. By including the 2012 AASM definition of mild OSA, the investigators will add novel information to the field by assessing the benefits of treatment in both sub-groups of mild OSA.

Detailed Description

Patients who visit their local sleep service for OSA investigation, and are found to have mild OSA (AHI ≤ 15) from an Apnealink polygraphy (PG) home sleep test, scored as per AASM 2007 and/or AASM 2012, will be invited to take part in the study (pre-screening).

At the study visit, informed consent, baseline demographics, and standardised questionnaires will be administered. Participants will then be randomised to a CPAP treatment group or control group.

After 3 months, participants will be asked to repeat the standardised questionnaires, the trial will then be complete and they will return to routine clinical care.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Continous Positive Airway Pressure
Participants in this group will use CPAP therapy, nightly, for the 3 month duration of the trial
Device: Continous Positive Airway Pressure
CPAP refers to the application of positive airway pressure through a mask and tubing to splint a patients throat open at night. CPAP is considered standard treatment for OSA
Other Names:
  • CPAP
Placebo Comparator: Control Group
Participants will receive standard care (Sleep hygiene counseling) during the study.
Other: Control Group
Standard sleep hygiene counseling as per published guidelines

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Quality of Life Using the Energy and Vitality Subscale of the Short Form 36 (SF-36) Questionnaire
Time Frame: 3 months

The Short Form 36 (SF-36) questionnaire measures quality of life through a range of questions asking about patients physical and mental functioning. Specifically, the Energy and Vitality subscale records patients perceptions of their levels of energy and fatigue. Participants were administered the Short Form 36 (SF-36) questionnaire at baseline and 3 months. The change in score (value at 3 months minus value at baseline) was compared between the CPAP group and the Control group.

In the SF-36 Energy and Vitality subscale, an increase in score indicates improvement, with a minimum score of 0 and a maximum score of 100 possible.
