ISRCTN - ISRCTN50028060: Study of perception of a new generation of continuous positive airway pressure (CPAP) device, PR1-PFlex

Plain English Summary

Background and study aims
Obstructive sleep apnea in its severe form is treated by Continuous Positive Airway Pressure (CPAP). CPAP delivers positive pressure in the upper airway of the patient through a nasal mask or nasal-oral mask and a circuit during sleep.
The benefits of CPAP treatment have been extensively researched. It has been established that the more a patient uses treatment during sleep the better the clinical benefit is. However, the number of patients not using the device properly or who stop using the device after one year is high. The major challenges of CPAP treatment are to reduce constraints surrounding the use of the device and to maximize the amount of time used during sleep.
The aim of the study is to assess the comfort and subjective satisfaction of patients using a CPAP new generation (PR1-PFlex) with advanced technology for comfort.

Who can participate?
Patients with Obstructive Sleep Apnoea Syndrome (OSAS) using an existing device.

What does the study involve?
The patients will undergo a medical examination. They will complete a series of questionnaires and data will be obtained from their current device. After seven days, they will be visited at home and the study device will be given to the patient and explained. After the study device has been used for about seven days the patient will be sent in the post some questionnaires to complete and a new data recording card. The patient will need to return the completed questionnaires and the data recording card from the study device to the investigator. Full instructions will be given to the patient.

What are the possible benefits and risks of participating?
The PR1-Pflex device has a current CE mark, is available for sale in Europe and will be used within the scope of its intended use in this study. The benefit to patients with OSAS is to use a more comfortable CPAP device which should significantly reduce the pressure level without impacting the effectiveness of treatment. Apart from known minor risks relating to CPAP, there are no additional risks or benefits.

Study information

Scientific title

Prospective multicenter study of a new generation CPAP device, PR1-PFLEX in patients with Obstructive Sleep Apnea Syndrome.

Acronym

Study hypothesis

The PR1-PFlex CPAP device will be perceived by patients as at least equivalent in terms of size, noise, ease of use, quality of sleep and overall satisfaction when compared to their existing device.

Condition

Obstructive Sleep Apnea

Intervention

Patients treated for OSA with a CPAP for which a change machine should be considered will be recruited during their annual follow-up visit.
During the inclusion visit are collected:
- The first questionnaire (called "Questionnaire de satisfaction PRE-TEST"), to assess patient satisfaction with respect to the device with which he was treated so far, is filled at the inclusion visit.
- The Epworth Sleepiness Scale.
- The Sleep Quality questionnaire (Saint Mary'Hospital Questionnaire) to assess subjective sleep quality patient.
- The compliance (data in hours/night and number of days/week), recorded by the machine on SD card and obtained by the embedded software of PPC and the P90.
The CPAP device is changed to the PR1-P Flex, which will be used for at least 7 days.
At the end of this period are collected (completed by the patient at home and sent to the investigator by mail):
- The second questionnaire (called "Questionnaire de satisfaction POST-TEST") to reassess the patient's satisfaction with respect to his former unit, evaluate the satisfaction of the PR1-P Flex, and assess his preference between the two devices
- The Epworth Sleepiness Scale
- The questionnaire to reassess subjective sleep quality patient, Saint Mary's Hospital Questionnaire
- The compliance data (in h/night and number of days/week), recorded by the machine on SD card and obtained by the embedded software of PPC and the P90.
The patient may keep the device PR1 P-Flex if desired, or return to the previous device.
The CRF will be completed by the physician investigator after each patient contact. It is from these data that will be calculated by statistical analysis of the test results.

Primary outcome measures

The primary endpoint of this study is based on patient satisfaction. This satisfaction assessment will be by means of two satisfaction questionnaires (before and after use of the device Questionnaire (Questionnaire PRE-TEST and Questionnaire POST-TEST).

Secondary outcome measures

The secondary endpoints of the study are:
1. Assessing sleepiness (Epworth scale) and sleep quality (Saint Mary's Hospital Questionnaire)
2. Evaluate the data recorded by the device, such as:
2.1. Compliance and % sleep time
2.2. The residual AHI
2.3. The P90 represents the effective pressure required to remove obstructive events during at least 90% of the night.
