Intervention/exposure
Study type
Interventional
Description 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).

Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This was a cluster randomised trial. Hospitals (not patients) were randomised to implement the guideline or remain as controls. After agreeing to participate in the study, hospitals were randomised using a centralised computer program developed in SAS.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation, stratifed by key hospital characteristics (bed number), generated using SAS.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Cluster randomised. Hospitals (not patients) were randomised to receive and implement and evidence-based guideline or to remain as control (no guideline) hospitals.

Summary
Brief summary
Nutritional support is accepted as a standard of care for critically ill patients although there is little agreement as to how it is best provided. Use of evidence-based guidelines has been shown to improve the effectiveness of care. The purpose of this project is to develop, promote and evaluate evidence-based clinical practice guidelines for nutritional support in the ICU in twenty-six hospitals throughout Australia and New Zealand. One half of the hospitals will be randomised to receive educational sessions based on the content of the guidelines using previously proven and accepted educational strategies. A cluster randomised trial will then evaluate the impact of these educational sessions on acceptance of the guideline and on patient outcomes.
