In this paper we describe the present range of organizations that have a ro
le in the early warning of new and emerging health care technologies in the
United Kingdom. We discuss in more detail the processes and prioritization
criteria used by the U.K. horizon-scanning project for the NHS Health Tech
nology Assessment Programme, and the principal methods of technology identi
fication for the horizon-scanning project are outlined. The United Kingdom
plans to develop an integrated system for the identification of technologie
s for commercial planning, health service research prioritization, financia
l planning, and provision of information to policy makers, purchasers, and
providers of health care.
