This symposium, held on 21 October 2011, was a joint venture between the Social Care Institute for Excellence (SCIE) and two ACN projects: Built Infrastructure for Older People’s Care in Conditions of Climate Change (BIOPICCC) and Design and Delivery of Robust Hospital Environments in a Changing Climate (DeDeRHECC). Taking the central theme of risk, its impact and meaning for service provision, and the care of people in vulnerable circumstances, over 50 experts from health, social care, planning, security, transport and the insurance industry explored responses to risk in general and climate change in particular.
