Prospectus conducted a National Review of Adult Critical Care Services in the Republic of Ireland. This large scale project required an in depth review of the current service, including visiting every hospital in Ireland with a critical care service, and undertaking a detailed data collection process. Following analysis of international practice, and a modelling exercise to project future demand, a proposal for the future design of critical care services was developed. The proposed future model included recommendations on type and distribution of services, staffing, education, work practices, transport, quality, and audit.
