Does OSA Increase Risk for Cancer?: A Large Historical Sleep Clinic Cohort Study.

Background: The relationship between OSA and cancer is unclear.

Research Question: What is the association between OSA and cancer prevalence and incidence in a large Western Australian sleep clinic cohort (N = 20,289)?

Study Design And Methods: OSA severity was defined by apnea-hypopnea index (AHI) and nocturnal hypoxemia (duration and percentage at oxygen saturation < 90%) measured by in-laboratory polysomnogram. Measures of potential confounding included age, sex, BMI, smoking status, socioeconomic status, and BP.

Telemedicine compared to standard face-to-face care for continuous positive airway pressure treatment: real-world Australian experience.

Study Objectives: We tested a telemedicine model of care to initiate continuous positive airway pressure (CPAP) for patients with obstructive sleep apnea (OSA) living in remote Western Australia.

Methods: A prospective study comparing telemedicine for CPAP initiation in a remote population versus standard face-to-face CPAP initiation in a metropolitan population. The primary outcome was average nightly CPAP use in the final week of a CPAP trial.

Continuous positive airway pressure and adverse cardiovascular events in obstructive sleep apnea: are participants of randomized trials representative of sleep clinic patients?

Study Objectives: Randomized controlled trials (RCTs) have shown no reduction in adverse cardiovascular (CV) events in patients randomized to continuous positive airway pressure (CPAP) therapy for obstructive sleep apnea (OSA). This study examined whether randomized study populations were representative of OSA patients attending a sleep clinic.

Methods: Sleep clinic patients were 3,965 consecutive adults diagnosed with OSA by in-laboratory polysomnography from 2006 to 2010 at a tertiary hospital sleep clinic.
