Central Sleep Apnea, Cheyne-Stokes Respiration, Complex Sleep Apnea, Mixed Sleep Apnea
Conditions
Brief summary
This multi-center observational study will prospectively collect data from patients who have an indication for servo ventilation therapy. This registry is intended to characterize the patient populations that may benefit from DreamStation BiPAP autoSV therapy (PR DS-autoSV, Philips Respironics, Monroeville, PA) in real life settings. In addition, this registry will assess adherence to the PR DS-autoSV therapy, the therapeutic benefits, collect morbidity and mortality data of servo ventilation in patients with central sleep apnea (CSA) and complex sleep-disordered breathing (SDB).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Short term Device usage and therapy adherence | 6 months | Device usage (hours/ night). Patients will be classified into various adherence subgroups based on the average daily device use at each study interval. The percentage of participants in each of the adherence subgroups will be presented. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Health-related quality of life | 6, 12 and 24 months | European Quality of Life-5 Dimensions questionnaire EQ 5D- 5L) is a standardized instrument for measuring generic health related quality of life. This tools scores range from 1 to 5, with higher scores indicating more problems across five dimensions (5D) which comprise mobility, self-care, usual activities, pain/discomfort, and anxiety/depression |
| Change in Subjective sleep quality | 6, 12 and 24 months | Pittsburgh Sleep Quality Index (PSQI) |
| Change in Daytime sleepiness. | 6, 12 and 24 months | Epworth Sleepiness Scale (ESS). This test consists of eight questions of daily life activities with a number from 0 (not at all likely to fall asleep) to 3 (very likely to fall asleep) which yields a score of 0 to 24, and subjectively quantify sleepiness.25 An ESS score ranging from 0 to 10 is interpreted as normal, scores of 11 to 24 is considered to be abnormal and indicative of increasing levels of excessive daytime sleepiness. |
| Long term Device usage and therapy adherence | 12 months | EDevice usage (hours/ night). Patients will be classified into various adherence subgroups based on the average daily device use at each study interval. The percentage of participants in each of the adherence subgroups will be presented. |
| Mortality | 6, 12 and 24 months | Frequency of death in patients who showed adherence to therapy as compared to those with non-adherence |
| Causes of death | 6, 12 and 24 months | causes of death , if available, will be compared in patients who showed adherence to therapy as compared to those with non-adherence |
| Number of healthcare utilization | 6, 12 and 24 months | Number of hospitalizations during the minimum of one year follow-up, time to first hospitalization, composite number of unscheduled visits to emergency rooms and/or physician's office) in patients who showed adherence to therapy as compared to those with non-adherence (if data is available) |
| Change on PSG/PG Parameters from baseline | 6 months | Disordered breathing events |
