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

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02699463

Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Obstructive Sleep Apnea Device: Continous Positive Airway Pressure Other: Control Group Not Applicable

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.

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 Name: 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 :
  1. Change in quality of life using the SF-36 questionnaire [ Time Frame: 3 months ]
    Point change in energy and vitality component of questionnaire compared with control group after three months CPAP usage
