Importance:
Drug-induced sleep endoscopy (DISE) could be valuable to determine an appropriate therapeutic pressure for obstructive sleep apnea (OSA).
Objective:
The continuous positive airway pressure (CPAP) determined by DISE was regarded as equal to the conventional titrating pressure. There is no study comparing the DISE-titrating pressure and the home-based automatic CPAP (APAP) titrating pressure. This study compared the DISE-titrating pressure, conventional titrating pressure, and home-based APAP titrating pressure.
Design:
Retrospective comparative cohort study.
Setting:
This study was conducted in a single medical center in Taiwan.
Participants:
A total of 59 participants with OSA who had 3 titrating pressures determined by DISE, conventional titration and home-based APAP titration were analyzed.Interventions or Exposures:Therapeutic CPAP pressure was determined by 3 methods: DISE, conventional titration, and home-based APAP titration.
Main Outcome Measures:
Home-based APAP titrating pressure was determined as 90% to 95% of APAP used at home for 2 weeks. The DISE-titrating pressure was determined manually based on direct visualization of upper airway patency during DISE examination. The conventional titrating pressure was determined manually under polysomnography (PSG) guidance in a sleep center. The correlation and difference between these 3 pressures were analyzed.
Results:
The home-based APAP titrating pressure, conventional titrating pressure, and DISE-titrating pressure were 8.8, 8.1, and 8.2 cmH2O, respectively. Good reliability was observed in pairs between all 3 pressures. The DISE-titrating pressure and the conventional titrating pressure were lower than the home-based APAP titrating pressure. There was no difference between the DISE-titrating pressure and the conventional titrating pressure.
Conclusions:
DISE could help provide a therapeutic CPAP pressure similar to the conventional titrating pressure in sleep center and APAP titrating pressure at home.
Relevance:
DISE could be a valuable alternative titrating method, especially in countries where PSG is expensive, time-consuming and difficult to access, and could facilitate earlier and more effective management of patients with OSA.
