The service design provides medium term admissions (2 to 8 weeks, average around 4 weeks) to facilitate complex assessments unsuitable for short term intervention available in specialist NHS neurological assessment services. 

Prior to admission, the length of assessment is planned in agreement with a Specialist Consultant and the referring NHS health board.

A number of factors influence the actual admission period including diagnostic issues and therapeutic changes being made.

When occasionally an extension of admission period is required over the pre-agreed timescale, authority is sought from the supporting NHS health board.
