0516 Alice NightONE™ vs WatchPAT ™: How Do These Two Home Sleep Apnea Tests Compare to One Another?

Introduction

Home sleep apnea testing allows patients to test and receive prompt treatment for obstructive sleep apnea (OSA). We wanted to compare a traditional device such as the Alice NightOne™ to a newer device called WatchPAT™.

Methods

We looked at 119 studies using Alice NightOne™, as well as 120 studies using WatchPAT™. We compared the results of the two devices with the goal of calculating the total positive and negative results, the severity of sleep apnea, and the number of patients who were started on treatment. Sleep apnea severity was classified as mild, moderate, and severe.

Results

Of the 119 patient who underwent Alice NightOne™, 78.15% (93/119) had OSA. There were 66 females and 53 males, with an average age of 49.08 years, BMI of 35.20 kg/m2 and ESS of 8.2. Of the patients diagnosed with sleep apnea, 48.39% (45/93) were diagnosed with mild OSA, 22.58% (21/93) with moderate OSA and 29.03% (27/93) with severe OSA. 54.84% (51/93) patients were treated with CPAP therapy, while 21.51% (20/93) patients were recommended to have a titration study and 23.66% (22/93) patients were lost to follow up. Of the 120 patients who underwent WatchPAT™ study, 70.83% (85/120) had OSA. There were 56 females and 64 males, with an average age of 46.04 years, BMI of 35.99 kg/m2 and ESS of 9.1. 42.35% (36/85) were diagnosed with mild OSA, 21.18% (18/85) with moderate OSA and 36.47% (31/85) with severe OSA. Of the 85 patients who were diagnosed with sleep apnea, 87.06% (74/85) patients were treated with CPAP therapy, while 3.53% (3/85) patients refused therapy and 9.41% (8/85) patients were lost to follow up.

Conclusion

Based on the results of testing, we found that the diagnostic utility between the two modalities was comparable. WatchPAT™ was able to identify 70.83% of patients with OSA, while NightOne™ was able to identify 78.15%. Of the patients identified with sleep apnea, 54.84% of patients undergoing NightOne™ were started on CPAP therapy and 87.06% of patients undergoing WatchPAT™ were started on PAP therapy.
