A critical review of the systems approach within patient safety research.
The application of concepts, theories and methods from systems ergonomics within patient safety has proved to be an expanding area of research and application in the last decade. This paper aims to take a step back and examine what types of research have been conducted so far and use the results to suggest new ways forward. An analysis of a selection of the patient safety literature suggests that research has so far focused on human error, frameworks for safety and risk and incident reporting. The majority of studies have addressed system concerns at an individual level of analysis with only a few analysing systems across multiple system boundaries. Based on the findings, it is argued that future research needs to move away from a concentration on errors and towards an examination of the connections between systems levels. Examples of how this could be achieved are described in the paper. The outcomes from the review of the systems approach within patient safety provide practitioners and researchers within health care (e.g. the UK National Health Service) with a picture of what types of research are currently being investigated, gaps in understanding and possible future ways forward.
