Some unanticipated consequences of the implementation of a hospital IT system: learning from a case study

Abstract

Technology offers potentially attractive solutions to patient safety concerns. Evidence is accumulating that errors can be reduced and practitioner performance improved through the implementation of computerised prescribing systems (CPS), but few interventions are free of unanticipated consequences. The aims of this session are to: share the learning from a case study of a large acute hospital in the UK with a sophisticated CPS; explain how unanticipated consequences arise in the sociotechnical system, illustrate these with examples, both beneficial and potentially harmful, and identify how they affect patient safety; emphasise the importance of being vigilant to the effects on patient safety when new technology mixes with long established work patterns; and invite comment and discussion about how health care organisations can harness beneficial effects and mitigate potential harm
