analysis. Those with P values ≤.2 were included for multiple
linear regression.
Results: The UAS (n = 674) and CPAP (n = 514) groups
were similar in age (59.8 ± 10.9 vs 59.7 ± 13.6), sex (78% vs
75% male), and AHI (35.4 ± 14.4 vs 33.8 ± 14.0). The UAS
group was lighter (BMI 29.3 ± 3.9 vs 30.0 ± 3.4; P = .001),
with higher pretherapy and posttherapy ESS (11.4 ± 5.6 vs 8.6
± 5.3, P < .001; and 7.8 ± 4.7 vs 5.5 ± 4.0; P < .001, respectively). UAS usage was higher vs CPAP (6.4 ± 2.0 vs 5.2 ± 2.0
h/night; P < .001). For UAS, sex, BMI, and AHI were included
for regression, but only BMI and post-ESS remained correlated with usage. For CPAP, sex, AHI, and post-ESS were analyzed, but only sex and post-ESS remained.
Conclusions: Baseline AHI and baseline ESS did not predict
device usage. Only posttherapy ESS was correlated with
device usage in both cohorts.
Sleep Medicine
Predictors of 1-Year Adherence to Continuous
Positive Airway Pressure in Adult Patients With
Obstructive Sleep Apnea

Jinkun Xu; Mu He, MD; Jingying Ye, MD
Objectives: This study aimed to assess potential predictors
of 1-year adherence to continuous positive airway pressure
(CPAP) therapy in adult patients with obstructive sleep apnea
(OSA). We hypothesized that more apnea-hypopnea events
improved through therapeutic pressure would result in better
adherence to CPAP.
Methods: We prospected newly diagnosed adult patients
with OSA who accepted positive airway pressure treatment
after more than 14 days of therapy. We defined a new index to
evaluate the improved degree average single pressure: average pressure improvement index (APII) = (baseline apneahypopnea index - residual respiratory event index)/optimal
therapeutic pressure. Baseline demographic data, severity of
disease, airway anatomic characteristics, APII, and optimal
therapeutic pressure were entered in analyses to identify predictors of CPAP adherence at 1 year.
Results: A total of 223 subjects accepted CPAP treatment
(male/female = 187:36). The overall 1-year adherence was
54.3%. In the adherent group, there was greater severity of
disease, lower proportion of hypopnea, higher APII and optimal pressure, and larger tonsils. Logistic analysis showed that
optimal pressure, enlarged tonsil, and APII predicted good
adherence (P = .027, .008, and .046, respectively).
Conclusions: APII, enlarged tonsil, and optimal pressure predict CPAP adherence at 1 year.
Prognostic Indicators for Successful
Hypoglossal Nerve Stimulation Therapy
Avrahan Boroosan (Presenter); Anna Salapatas;
Phillip Anderson; Michael Friedman, MD
Objectives: This study was designed to identify prognostic
indicators associated with hypoglossal nerve stimulation
(HNS) therapy to treat obstructive sleep apnea (OSA), particularly focusing on patients' physiologic response to tongue
protrusion while awake. The hypothesis is that patients with
an improved airway on awake tongue protrusion may be better
candidates for HNS than patients whose airway dimensions
decrease with tongue protrusion.
Methods: We performed a chart review of 40 patients with
moderate to severe OSA who have undergone HNS therapy
surgery between December 2017 and December 2019. Data
abstracted include standard demographics, body mass index
(BMI), preoperative and postoperative apnea-hypopnea index
(AHI), Friedman tongue position, and tonsil size. Endoscopic
findings that identified changes in hypopharyngeal crosssectional area (CSA) with the patients' mouth open (MO) vs
mouth closed (MC) and the patients' tongue in neutral position (TN) vs tongue protruded (TO) were also abstracted.
Logistic regression analysis was performed to determine
which factors were relevant to a successful outcome. Success
of HNS therapy was considered a 50% reduction in AHI or an
AHI less than 20.
Results: Forty patients (67.0% male; age, 38.2 ± 9.4 years;
mean BMI, 27.4 ± 4.1 kg/m2) were included in this study. The
mean AHI decreased significantly from 39.8 ± 9.3 events/h
preoperatively to 17.7 ± 7.6 events/h postoperatively (P <
.0001). Higher rates of success were observed in patients with
positive changes in CSA with MC > MO and TO > TN.
Conclusions: Awake assessment of airway changes between
MO/MC and tongue out/tongue in may help predict the success of HNS therapy.
Regional Comparisons of Upper Airway
Stimulation Outcomes From the ADHERE
Registry
David Kent, MD (Presenter); Maurits Boon, MD;
Colin T. Huntley, MD; Maria V. Suurna, MD;
Ronald D. Hanson, MD; B. Tucker Woodson, MD;
Katherine K. Green, MD, MS
Objectives: Upper airway stimulation (UAS) is a surgical
option for continuous positive airway pressure-intolerant
obstructive sleep apnea (OSA) in the United States and
selected European countries. We compared regional outcomes
at 1 year from the ADHERE registry.
Methods: ADHERE includes data from the United States
and Europe (European Union: Germany, Netherlands, Belgium,
and Switzerland). Demographics, objective outcomes, and
subjective outcomes were collected.
Results: From 2016 to January 2020, 1643 subjects have been
enrolled, and 751 have completed 1-year follow-up. The average follow-up is 0.85 ± 0.59 years. The cohort is 70.54% male,
aged 60.33 ± 10.98 years, with a body mass index of 29.13 ±
3.86 kg/m2. The median apnea-hypopnea index (AHI) decreased
from 33 to 10 (mean, 35.92 ± 15.53 to 14.39 ± 14.74), and the
median Epworth Sleepiness Scale (ESS) reduced from 11 to 6
(mean, 11.24 ± 5.58 to 7.05 ± 4.57). Nightly usage was 6.4 ± 2.0
hours at 6 months and 5.6 ± 2.2 hours at 12 months. Subject
