Descriptions of intervention(s) / exposure
The study intervention involves the implementation of National-level guidelines for the provision of nutritional support in critical illness. 27 hospitals participated in this trial: 14 hospitals were randomised to the intervention group (guidelines implementation) and 13 were randomised to the control (standard care) group. The 14 intervention group hospitals received education on the content of the feeding guidelines and the 13 control hospitals received no education. Education was provided via a formal practice change strategy composed of Educational Outreach (one session, 45-60mins), Academic Detailing (as much as required), Posters, Active Reminders, Audit and Feedback and traditional in-servicing (as many sessions as required, 30-60mins per session).
