Automated Graduated CPAP (AGPAP) for Improved Adherence in Newly Diagnosed Obstructive Sleep Apnea (OSA) Patients
Automated Graduated CPAP (AGPAP) for Improved Adherence in Newly Diagnosed OSA Patients: Multicenter Trial

Detailed Description
Even though CPAP is highly effective in treating sleep apnea, adherence to CPAP therapy remains the largest single obstacle to the successful resolution of sleep-disordered breathing in OSA patients. It has been estimated that up to 50% of patients who have been prescribed CPAP for Obstructive Sleep Apnea (OSA) are not using the treatment one year later. A myriad of possible causes for low compliance rates have been proposed and examined in previous studies. These include race, gender, education level, income, bed-partner's sleep quality, mask discomfort, continuity of care, nasal irritation, discomfort due to elevated expiratory pressure, and level of daytime sleepiness.
Therefore, many investigators have proposed new methods and approaches to help deal with these problems. Interventions have ranged from people-centric approaches using intensive CPAP education and follow-up programs, to device modifications using features such as a ramp, C-FLEX®, BiLevel therapy, and heated humidification.
In this study. The aim of this study was to determine the effectiveness of the Automated Graduated CPAP (AGPAP), also know as EZ-start acclimation period, and its impact on short term adherence

Functional Outcome Sleep Quality (FOSQ)
Time Frame: 3 months
|
Functional Outcomes Sleep Questionnaire (FOSQ) is a self-administered instrument designed to assess the impact of excessive sleepiness on daytime function and to quantify improvement after treatment.
It contains 30 items divided into 5 subscales: Activity level, vigilance, intimacy and sexual relationships, general productivity, and social outcome.
The patient rates the difficulty of performing a given activity on a 4-point scale (no difficulty to extreme difficulty) A mean score is calculated for each scale ranging from 0 (maximum functional impact) to 24 (no functional impact).

Daytime Sleepiness as Measured by the Epworth Sleepiness Scale
Time Frame: 3 months
|
Epworth Sleepiness Scale (ESS) is a self-administered questionnaire with 8 questions.
Respondents are asked to rate, on a 4-point scale (0-3), their usual chances of dozing off or falling asleep while engaged in eight different activities.
The ESS score can range from 0 to 24.
The higher the ESS score, the higher is the overall 'daytime sleepiness'.
