Classification of facial phenotypes in Asian patients with obstructive sleep apnea

Sleep and follow-up characteristics of Hispanic patients: Insights from a comparative analysis with White patients in polysomnographic split-night studies

BACKGROUND

Limited attention has been given to exploring the efficacy of titration in split-night polysomnography (PSG) and the factors influencing adherence to continuous positive airway pressure (CPAP) therapy. This study aims to evaluate the severity of OSA and PSG parameters in HP compared to WP.

METHODS

Split-night PSG studies conducted on adults. Participants were categorized based on self-reported ethnicity as either HP or WP.

RESULTS

The study enrolled 50 WP (15 women, 35 men, mean age 60.5 ± 13.60 years, mean BMI 34.2 ± 7.48) and 45 HP (24 women, 21 men, mean age 54.9 ± 13.06 years, mean BMI 37.3 ± 7.88). HP exhibited a mean apnea-hypopnea index (AHI) of 51.1 ± 33.67, saturation nadir of 77.8 ± 10.19, and time spent with saturation <90% of 21.0 ± 26.93 min. In WP, the mean AHI was 39.2 ± 24.49, saturation nadir 81.6 ± 9.04, and time spent <90% was 10.4 ± 17.17 min. All observed differences were statistically significant (p < 0.05). Auto CPAP was prescribed to all patients, with adherence at 3-4 months being 75% ± 30 for HP, with a usage of 5.5 ± 2.2 h, and a residual AHI of 3 ± 3.5. In WP, adherence was 79% ± 30, usage was 5.9 ± 2.1 h, and residual AHI was 3.6 ± 6.2. None of these differences reached statistical significance. Among HP, 37% missed follow-up appointments compared to 12% of WP. More HP used full-face masks, while more WP preferred nasal masks.

CONCLUSIONS

HP exhibited significantly worse OSA parameters during the diagnostic phase of PSG compared to WP. HP had a significantly higher no-show percentage than WP. CPAP adherence and residual AHI were not statistically different, but more HP missed follow-up appointments than WP.

Marketing factors associated with a continuous positive airway pressure machine purchasing in patients with obstructive sleep apnea

Aim: Obstructive sleep apnea (OSA) is related with several cardiovascular diseases. It should be treated with a continuous positive airway pressure (CPAP) machine. There is limited data on marketing factors on a decision of CPAP machine purchasing in OSA patients. Materials & methods: We enrolled adult patients aged over 18 years with OSA who tried a CPAP. Marketing factors were evaluated for a decision of CPAP machine purchasing. Results: There were 95 OSA patients participated in the study. Nice color CPAP machine and good knowledge and informative salesperson had adjusted odds ratio (aOR) of 4.480 and 9.478, the other two factors had aOR at 0.102 and 0.217. Conclusion: Marketing factors related to CPAP machine purchasing in patients with OSA.
