Attain was commissioned by Suffolk and North East Essex ICS to model the current and future demand for eye care services within Suffolk and North East Essex ICS. The long-term purpose was to identify the existing and potential capacity of all eye care services across the ICS to inform the creation of a model to provide a sustainable service for the future. The short-term objectives were to identify current system demand, and to identify existing system capacity restrictions across workforce, equipment, estates, and IT (referral and payment).
