Home What we offer Sleep & respiratory medicine

Sleep & respiratory medicine

We provide comprehensive sleep medicine services including specialist consulting, diagnostic testing and sleep therapy.

Update

Please note that from 11 May 2020, GenesisCare will resume in-lab (overnight) and home sleep studies at our centres.

As we continue to face the uncertainty of COVID-19, providing ongoing access for patients who may be at increased risk due to sleep disorders is very important.

While providing high quality services, GenesisCare is complying with state and national advice and we have implemented a range of new safety measures to limit the risk of COVID-19.

We welcome all referrals for diagnostic sleep studies and CPAP treatment and support, and are pleased to provide essential medical care to your patients.

Our specialists and sleep therapists are facilitating both Telehealth and in person consultations if you wish to discuss anything with them.

For further information or support, please contact 1800 155 225 or infosleepqld@genesiscare.com.

FAQs

What other people ask

Better care starts with good sleep. GenesisCare provides a comprehensive service encompassing sleep physician consulting, sleep investigations (both in-hospital and at home sleep testing) and a full range of treatment options. It’s easy and convenient to get all the services you require.

Speak to a member of the team at your local GenesisCare centre.

Talk to your local doctor in the first instance. Your doctor will then write a referral for a sleep study if appropriate.

The gold standard for sleep testing is within a sleep laboratory with a sleep technician in attendance. Generally this is the first option. For patients that are suitable (depending on the sleep condition) home testing may be an option.

You will be in a private room and well looked after by the sleep technician on the night. Most patients sleep well and usually better than they anticipated.

GenesisCare provides Sleep Specialist consulting at all our region. Your review appointments will be either with a Sleep Specialist or with your referring doctor depending upon the requirements of yourself and your referring doctor.

Our aim is to make treatment affordable for all patients. Visit our payments page to find our more.

From 1 November 2018, MBS items for sleep studies are changing to ensure patients with proven sleep disorders are better identified and more appropriately managed. The changes will help doctors refer patients for the most suitable test for them, depending on how likely they are to have a sleep disorder.

For patients who do not meet the requirements for a rebatable sleep study, GenesisCare’s physicians are able to facilitate further investigation into symptoms.
