Harefield Hospital sleep clinic

Harefield Hospital provides a multidisciplinary consultant-led sleep service that provides assessment and management for patients with sleep disorders, typically obstructive sleep apnoea. We primarily offer home multi-channel sleep studies as we recognise that most people prefer sleeping in their own bed rather than in hospital.

The sleep clinic at Harefield Hospital is supported by specialist sleep technicians from the department of respiratory physiology, who provide comprehensive technical support and clinical nurse/physiotherapy specialists.

How to get referred

 We accept referrals from:

  • GPs
  • consultants
  • other healthcare professionals, including respiratory physiotherapists and nurse specialists.

GP referrals must be made through the e-referral service. Letters from other referrers should be addressed to the Department of Respiratory Medicine, Harefield Hospital, Hill End Road, Harefield, Middlesex, UB9 6HJ.

Please note: Referrals for professional drivers (HGV licence) with suspected obstructive sleep apnoea should be marked URGENT to ensure a fast-track sleep study service.

What you need to do before your clinic appointment

Prior to your clinic appointment, you will be asked to do a sleep study at home using the Embletta sleep monitoring device, which we will ask you to collect from the respiratory physiology department at Harefield Hospital. Watch a video on how to wear and use the Embletta device. 

What you need to bring to your appointment 

Please bring with you a list of your current medications and, if you can, list the medical conditions and/or procedures, including any operations, you have had in the past. We also recommend being accompanied by a partner, spouse or carer.  

What happens on the day of the clinic

On the day of your appointment you may be asked to have a chest X-ray (this is routine), and also fill in a questionnaire while you wait to be seen. You will then be seen by one of our respiratory consultants or a nurse specialist, who will review the results of your Embletta sleep study and discuss a plan of treatment, alongside any follow-up appointments you may need to attend.

What happens if you are prescribed CPAP 

If you have been prescribed treatment with CPAP (continuous positive airway pressure), we will ask you to collect your CPAP machine from the respiratory physiology department at Harefield Hospital. Watch a video on how to use a CPAP machine.
