Diagnostic sleep study service

This page has information for clinicians who want to refer for diagnostic investigations at the children's sleep service at Evelina London.



Available diagnostic investigations: elective

The department offers a number of different diagnostic investigations. 

Elective studies are booked 6-8 weeks in advance, and are intended to be carried out when children are generally well/at their normal baseline. It is usually not appropriate to carry out an elective sleep study when the child is unwell, and studies may be postponed if a child is unwell at the time of their planned study. 


Diagnostic investigations

Available diagnostic investigations: acute

We have very limited capacity to carry out urgent/acute sleep studies. 

All requests for an urgent sleep study must all be discussed with either a sleep consultant and/or the respiratory consultant on service.

Senior members of the paediatric sleep team are always happy to discuss patients and offer advice as to how the most appropriate diagnostic information for patients can be achieved as quickly as possible.

Cancellation slots

Where urgent studies are requested for out-patients, we are able to offer short-notice cancellation slots to families if these become available before their electively booked study date. Please indicate if families are happy to be offered appointments at short-notice on the request form, and include best contact details for them. Cancellation slots cannot be guaranteed.

If assessment is needed more urgently than this, then children would normally need to be admitted to Evelina London by their consultant, and options for assessment discussed with the sleep/respiratory teams. 

Available diagnostic investigations: acute
