Patient-Defined Goals for Obstructive Sleep Apnea Treatment

Video-Based Decision Aids Improve Sleep Surgery Decision-Making: A Randomized Controlled Trial

OBJECTIVES

Decisional conflict (DC) is high in obstructive sleep apnea (OSA) surgical candidates interested in positive airway pressure (PAP) alternatives. We evaluated the impact of pre-consultation video decision aids on patient DC and decision readiness.

METHODS

Prior to consultation for PAP alternatives, adult OSA patients were enrolled and completed a questionnaire querying DC (scored 0 [no conflict]-100 [high conflict]) and decision readiness. Those considering ≥3 treatment options were categorized as "high-conflict." Patients were randomized to either an intervention group with video review about PAP and surgical options prior to their visit or to a control group that received no video review. Audio recordings of clinic visits were analyzed for patient engagement.

RESULTS

Twenty-five participants (control: n = 12, intervention: n = 13) were found to have comparably high DC (mean score: 40.0). Both groups experienced post-visit improvements in DC scores (post-consult: 25.2, p = 0.003) which did not differ between the two groups (intervention: 20.5 ± 15.1 vs. control: 11.7 ± 12.1 points, p = 0.13). The intervention group showed significant improvement in decision-making stage after the visit, with 72.7% "close to selecting an option" (p = 0.04) versus 41.7% in the control group. Use of videos was not associated with any differences in patient satisfaction, engagement, or decision to pursue surgery (all p > 0.05). High-conflict patients (n = 5) who reviewed pre-visit videos (intervention sub-group) spoke fewer words during the visit (687 ± 139 vs. 1120 ± 389 words, p = 0.047) and had shorter visit times (18.7 ± 2.9 vs. 24.3 ± 3.1 min, p = 0.02) than high-conflict control patients.

CONCLUSIONS

Patients have high levels of DC when considering PAP alternatives. Use of video decision aids prior to sleep surgery consultation may improve the treatment decision-making process.

Impact of Hypoglossal Nerve Stimulation on Consumer Sleep Technology Metrics and Patient Symptoms

OBJECTIVES

Obstructive sleep apnea (OSA) is usually assessed at discrete and infrequent timepoints. Wearable consumer sleep technologies (CST) may allow for more granular and longitudinal assessments of OSA therapy responses and OSA-related symptoms.

METHODS

In this case series, we enrolled hypoglossal nerve stimulator (HGNS) patients who had an effective treatment response for an 8-week study using a wearable CST. Participants started with "HGNS-on," were randomized to turn off HGNS therapy during either week 4 or 5 ("HGNS-off"), followed by a return to therapy, "HGNS-resume." Participants completed validated symptom questionnaires assessing sleepiness, insomnia symptoms, functional status, and overall sleep health (Satisfaction, Alertness, Timing, Efficiency, and Duration, SATED) each week. CST metrics and survey scores were compared between HGNS treatment phases. Associations between CST metrics and survey scores were assessed.

RESULTS

Seven participants with a total of 304 nights of CST data showed no statistically significant changes in total sleep time (TST), wake time after sleep onset, or sleep efficiency (SE) across the study periods. During HGNS-off, survey scores indicated significantly worsened OSA-related symptom scores. Two participants had significantly higher heart rate variability (HRV) during HGNS-off (by 3.3 and 6.3 ms) when compared to HGNS active therapy periods. Amongst CST metrics, SATED scores correlated with TST (r = 0.434, p < 0.0001), HRV (r = -0.486, p < 0.0001), and SE (r = 0.320, = 0.0014). In addition, FOSQ-10 scores correlated with average HR during sleep (r = -0.489, p < 0.001).

CONCLUSION

A 1-week HGNS therapy withdrawal period impacted OSA-related sleep symptoms. Sleep-related metrics measured by a wearable CST correlated with symptom scores indicating potental value in the use of CSTs for longitudinal sleep-tracking in OSA patients.

Snoring Patterns During Hypoglossal Nerve Stimulation Therapy Up-Titration

Longitudinal snoring changes can be captured using a mobile phone application. During hypoglossal nerve stimulator (HNS) therapy up-titration, increasing stimulation voltage was associated with reduced snoring frequency and intensity in this case series of six patients.

International Consensus Statement on Obstructive Sleep Apnea

BACKGROUND

Evaluation and interpretation of the literature on obstructive sleep apnea (OSA) allows for consolidation and determination of the key factors important for clinical management of the adult OSA patient. Toward this goal, an international collaborative of multidisciplinary experts in sleep apnea evaluation and treatment have produced the International Consensus statement on Obstructive Sleep Apnea (ICS:OSA).

METHODS

Using previously defined methodology, focal topics in OSA were assigned as literature review (LR), evidence-based review (EBR), or evidence-based review with recommendations (EBR-R) formats. Each topic incorporated the available and relevant evidence which was summarized and graded on study quality. Each topic and section underwent iterative review and the ICS:OSA was created and reviewed by all authors for consensus.

RESULTS

The ICS:OSA addresses OSA syndrome definitions, pathophysiology, epidemiology, risk factors for disease, screening methods, diagnostic testing types, multiple treatment modalities, and effects of OSA treatment on multiple OSA-associated comorbidities. Specific focus on outcomes with positive airway pressure (PAP) and surgical treatments were evaluated.

CONCLUSION

This review of the literature consolidates the available knowledge and identifies the limitations of the current evidence on OSA. This effort aims to create a resource for OSA evidence-based practice and identify future research needs. Knowledge gaps and research opportunities include improving the metrics of OSA disease, determining the optimal OSA screening paradigms, developing strategies for PAP adherence and longitudinal care, enhancing selection of PAP alternatives and surgery, understanding health risk outcomes, and translating evidence into individualized approaches to therapy.
