The bidirectional link between sleep and pain is a widely accepted concept. While there has been much focus on this in recent years, studies investigating obstructive sleep apnoea (OSA) and chronic pain are still not very common, especially in context of continuous positive airway pressure (CPAP) therapy.
In this study, people recently diagnosed with OSA, a common sleep disorder, that are receiving a CPAP mask are asked to fill in questionnaires at baseline, 3- and 6-month follow-up. Data of people with and without chronic pain will be collected and we will use the data will allow us to answer a number of clinically relevant questions. The primary questions investigate the following: 1) The association of CPAP adherence and pain outcomes with CPAP therapy at 3-month follow-up; 2) The association of baseline Apnoea-Hyopnea-Index on pain outcomes with CPAP therapy at 3-month follow-up. Secondary questions investigate the relevance of co-morbid insomnia (COMISA), the influence of chronic pain on CPAP adherence and general clinical outcomes of CPAP therapy in people with chronic pain.
Participants must be 18 years of age or older
Participants must be able to read and write in Dutch, French or English
AHI ≥ 15
Prescribed CPAP for the first time as a treatment for their OSA
Participants who are currently receiving CPAP treatment or have had a CPAP treatment in the last year
Participant receiving CPAP for other conditions than OSA (e.g. Central Sleep Apnoea)
The target group for the study consists of adult, Dutch, French or Englisch speaking patients who have been referred to the sleep clinic. These patients have been diagnosed with OSA and will start to receive CPAP treatment. They are included independent of their chronic pain status but some analyses will be done in sub-groups.
Cohort
Prospective
Standard OSA care
Other interventionAll people will undergo standard care.
Average Pain during last 1 week
Participants are asked for the average pain they had during the last 1 week. They answer on a scale for 0-10 with 0 being no pain and 10 being the worst pain ever. This is a single question taken from the Brief Pain Inventory
CPAP adherence
Average CPAP use in hours per night as measured by the CPAP device
Prevalence of chronic pain in people with OSA undergoing CPAP treatment
Chronic pain defined as pain anywhere in the body that is present every day or most days for 3 months or longer and that regularly impairs quality of life or ability to do activities (leisure, work).
Average Pain during last 1 week
Participants are asked for the average pain they had during the last 1 week. They answer on a scale for 0-10 with 0 being no pain and 10 being the worst pain ever. This is a single question taken from the Brief Pain Inventory
Fatigue (Mental and Physical)
Measured using the Brugmann Fatigue scale - 0-12 for each subscale (Mental fatigue and physical fatigue with 0 indicating no fatigue and 12 severe fatigue)
