The Impact of Daily Sinus Irrigation on Nasal Symptoms in Continuous Positive Airway Pressure (CPAP) Users - A Pilot Study

May 11, 2010 updated by: Bridgeport Hospital
Continuous positive airway pressure (CPAP) is the most commonly used treatment for obstructive sleep apnea. Nasal symptoms such as dryness, itching and congestion are common in CPAP users. Nasal and sinus saline irrigation has been shown to improve these symptoms in individuals with chronic nasal congestion and sinusitis. This is an 8 week study that investigates whether daily saline nasal and sinus irrigation reduces nasal symptoms in patients using CPAP, improves quality of life and CPAP compliance.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
RQLQ (Rhinoconjunctivitis Quality of Life Questionnaire)
Time Frame: 4 weeks
A 28-item, self administered questionnaire measuring nasal symptoms and other domains, including activity limitations and eye symptoms. Subjects will be asked to rate their symptoms on a 7-point scale (0=no impairment, 6=severely impaired). Change in RQLQ with daily saline irrigation in CPAP users is the primary outcome of interest.
4 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Epworth Sleepiness Scale
Time Frame: 4 weeks
The Epworth Sleepiness Scale is a self administered questionnaire that measures subjective daytime hypersomnia on a scale of 0 to 24.
4 weeks
SF-36
Time Frame: 4 weeks
The Medical Outcome Study 36-Item Short Form health survey (SF-36) is a 36-item questionnaire which measures 8 domains of health: physical functioning, physical problems, emotional problems, social functioning, mental health, energy/vitality, pain, and general perception of health status. This questionnaire has been used as a validated measure of change in the quality of life of OSA patients on CPAP therapy.
4 weeks
CPAP compliance
Time Frame: 4 weeks
CPAP card compliance data will be measured to determine if use of daily sinus rinse is associated with an increase in CPAP use. The % of days CPAP used over 4 weeks and the average number of hours of CPAP use per night are the outcomes of interest.
4 weeks
