About this study

Official title: Evaluation of New Diagnostic and Treatment Algorithm for Obstructive Sleep Apnea in High Risk Population in Hong Kong

Newer home sleep study device and algorithm provides an alternative for inpatient sleep study and improve the service provides to patients

Read the detailed description

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.

Questions about this trial

What is this clinical trial studying?

A study testing home sleep study, home CPAP titration (Autoset) and CPAP in people with Sleep Apnea, run by Chinese University of Hong Kong at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Jul 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Validity of the new home sleep study device compare with conventional inpatient sleep study (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jul 2009.
