Practicality of the Sleepstrip™ in postal screening for obstructive sleep apnoea
The SleepStrip™, a disposable screening device for the detection of obstructive sleep apnoea (OSA), which displays an estimated apnoea–hypopnoea index (AHISS) was posted, with instructions, to 48 patients referred for sleep study for suspected OSA. The patients subsequently underwent a cardiorespiratory sleep study from which the AHIE was derived. Thirty patients (63%) returned the SleepStrip™, the device displayed an AHISS in 22 patients (73%), of which 17 (57%) was deemed valid by the device. Twelve of the 30 patients who returned the SleepStrip™ had an AHIE ≥ 20 on the detailed sleep study. Of these, the SleepStrip™ recording was valid in seven of which only two had an AHISS ≥ 20. We concluded that the SleepStrip™ was not suitable for unsupervised postal screening for OSA.
