Research summary
Waiting lists for Obstructive Sleep Apnoea (OSA) diagnosis have grown nationally, with current clinical departments and pathways unable to meet the demand. OSA is a disorder where breathing stops for more than 10 seconds during sleep, causing drops in blood oxygen levels and disturbed sleep. Current diagnostic tests either lack sensitivity (oximetry) or require manual reporting (WatchPAT). In December 2024, the National Institute for Health and Care Excellence (NICE) published guidelines for wearable OSA diagnostic devices which are relatively new to the specialism and included the Sunrise device in the recommendation. Sunrise is a small, non-invasive sensor that offers a simple, no-reporting solution for diagnosing OSA. However, its use in NHS services is limited, and further research is needed.
This study aims to compare Sunrise’s performance with oximetry and WatchPAT in assessing suspected OSA patients and evaluate its potential for inclusion in standard diagnostic pathways. If the hypothesis is supported, Sunrise could reduce patient pathway time, enabling faster diagnoses and shorter waiting lists, as it requires no analysis time compared to WatchPAT. Sunrise may also be more sensitive than oximetry, reducing the need for additional tests. The study will assess whether patients find Sunrise easier to use and could improve patient experience by minimising travel to a city centre hospital with limited parking. Feedback on transport and time off work will evaluate the impact of posting devices to patients' homes.
Patients with suspected OSA referred to the adult sleep service will undergo either oximetry or WatchPAT as part of the standard clinical pathway and will be screened for study recruitment. This single-site study at University Hospitals Bristol and Weston NHS Foundation Trust (UHBW), will involve patients using both Sunrise and either oximetry or WatchPAT for one night. Participants will return the equipment two days later and continue their clinical care pathway.REC name
