Weaning from ventilation: does a care bundle approach work?

There has been renewed interest in weaning from mechanical ventilation in critical care since the publication of the Modernisation Agency paper in 2002. There have been many papers reporting ways of improving the weaning process but these are specific to single elements and neglect the contextual issues that influence the weaning process. Care bundles have been introduced nationally to standardise patient care and improve patient outcome. Examples in critical care are the ventilator care bundle and sepsis care bundle. However, since care bundles have become linked with targets and part of the 10 High Impact Changes there is a tendency to want to call everything a care bundle. A care bundle is a small but critical set of processes that when implemented together improve outcome. One critical care network has written a weaning care bundle. This is an example of a service improvement initiative the aim of which was to improve weaning from mechanical ventilation. This paper reviews this approach and presents results from a pilot in one teaching hospital.
