Sleep assessment

Whakamātaunga moenga

If your doctor thinks you have obstructive sleep apnoea (OSA) or another sleep disorder, they may recommend that you have a sleep assessment at the hospital.

You may prefer to pay to see a private sleep clinic.

A sleep assessment takes around half an hour. If you qualify, the cost is subsidised by Te Whatu Ora.

Getting a sleep assessment

A sleep assessment involves several tests, including:

The person doing the assessment will ask you questions about your sleep, your lifestyle and daily routine, what you normally eat and drink, your job, your family history and what medications you take. This is to give the assessor a better idea of what might be affecting your sleep and how badly your sleep is affecting your lifestyle.

They may ask you to complete two questionnaires.

The questionnaire results will be filed with your sleep assessment documentation and looked at by Christchurch Hospital's Sleep Health Services when they review your sleep assessment report.

You may be asked to undergo an overnight oximetry test. You'll be given an oximeter to take home and wear while you sleep. On the night of the study, you'll need to keep a sleep diary (this also includes instructions for using the oximeter). Return the oximeter and diary to the assessor the next day. The results will be included in the sleep assessment report.

After a sleep assessment

The assessor will send the completed report and documents to Christchurch Hospital's Sleep Health Services who will review it. They will send a report back to your general practice team. This will determine if you have OSA or another sleep disorder, and what type of treatment (if any) should be tried.
