Cost analysis of the current sleep service compared with estimated costs of alternative models of care with varying types of sleep studies, and assuming different rates of surgery (50 %, 68 %, or 80 %) in children assessed by clinical criteria alone.

A HRG coding tariff of £348 was used for estimating the costs of home multi-channel studies and £170 for home oximetry.
