Introducing new technology safely.

AIM: This report considers the introduction of new technology and the implications for patient safety. METHODS AND DISCUSSION: A distinction is made between 'conceptually' new and 'contextually' new technology. The life cycle of technology from development to routine use is discussed and the key role for regulation, health technology assessment, clinical engineering and surveillance in this life cycle considered. The limitations of each of these disciplines are also discussed. Special consideration is given to the needs of developing countries. Case study examples of particular challenges in the safe introduction of technology are presented.
