Overview
We have an ongoing investigator initiated, randomized controlled trial based on an innovative clinical approach leveraging a group-based dynamic, i.e., the sleep apnea management group clinic effect on positive airway pressure (PAP) adherence, PAP barriers, and patient reported outcomes. In this trial the group approach outcomes are compared to the usual care outcomes.
Another research focus has been to characterize the effect of Positive Airway Pressure (PAP) therapy for Obstructive Sleep Apnea (OSA) on patient reported outcomes (PROs). We have examined changes in quality of life measures, depressive symptoms, drowsy driving, and restless legs syndrome symptoms correlated with the use of PAP therapy and PAP therapy adherence in patients with OSA. Further, we examined the impact of age, gender, and socioeconomic status on these measures.
A final area of focus examines the impact of sleep apnea therapies on PROs in hypertensive and resistant hypertensive individuals.
