Limerick East): The approach in the health strategy, Shaping a Healthier Future, to the development of acute services is focused on developing regional self-sufficiency in acute hospital services. Additional funding has been allocated to health boards in recent times to widen the range of services provided on a regional basis to improve access to specialist services. The development of such improved services at a regional level reduces the need for patients to seek treatment outside their local health board area. In certain cases it is not feasible to provide particular services on a regional basis, due to the high degree of specialisation and size of patient population required to sustain a viable service, and in such cases, specialised supra-regional units provide specialist services which serve much wider catchment areas and concentrate resources nationally to the best effect.
