Device: home CPAP titration (Autoset)
continuous positive airway pressure device for treatment of sleep apnea
Other Name: Autoset
Device: home sleep study
different in algorithm arrangement for diagnosing sleep apnea
Other Name: different algorithm arrangement
Purpose: Assess different potential algorithms to improve the service and cost utility for diagnosis and treatment of obstructive sleep apnea syndrome (OSAS) in patients with high pretest probability in Hong Kong.
Hypothesis: Newer home sleep study device and algorithm provides an alternative for inpatient sleep study Design: Prospective randomized study Subject: High pretest probability of OSAS patients referred to a tertiary centre.
Study instruments: a portable sleep study device, AutoCPAP and inpatient sleep monitoring system.
Interventions: comparison between 3 different algorithms of health service for OSA patients would be made: conventional in-patient sleep study, empirical treatment and home sleep study.
Main outcome measures: The primary outcome is the validity of the home sleep study device compare to inpatient sleep study. The secondary outcomes are the relative efficacy of different algorithms and the numbers of failed procedures in each algorithm.
