• Feasibility of the study design and intervention [ Time Frame: 12 months post implementation of intervention ] [ Designated as safety issue: No ]
  Assessed by rate of completion of barriers questionnaires, development of unique tailored action plans at each site, compliance and satisfaction with the tailored action plans, and other user feedback.
  
  

• Change in nutrition performance score [ Time Frame: 20-24 months ] [ Designated as safety issue: No ]
  The nutrition performance score is a composite measure including use, timing and adequacy of nutrition, use of small bowel feeds and motility agents, and hyperglycemia. Nutrition performance scores will be calculated after each of the two nutrition practice audits.
  
  
• Change in barriers to implementation of critical care nutrition clinical practice guidelines [ Time Frame: 12 months post implementation of intervention ] [ Designated as safety issue: No ]
  Barriers questionnaire
  
  

A before-after study will be conducted in 7 Canadian and US ICUs. Each participating ICU will implement a tailored guideline implementation intervention aimed at narrowing the guideline-practice gap. The tailored implementation will consist of 4 phases:

1. Audit of Nutrition Practices: The nutrition practice audit will be conducted as part of the data collection for our ongoing international nutrition quality improvement project. This involves collecting data on personal characteristics and nutrition therapy in a consecutive cohort of 20 mechanically-ventilated critically ill adult patients. Performance at each ICU will be assessed by a benchmarked report comparing the nutrition practices to individual recommendations of the Canadian Critical Care Nutrition CPGs, thus enabling identification of the ICUs strengths and weaknesses, and highlighting areas to target for improvement.
2. Barriers Questionnaire: The barriers and enablers questionnaire will be completed by all physicians, all ICU leadership, the dietitian(s), and a random sample of 30 full- and part-time nurses. This questionnaire asks questions about barriers associated with guideline implementation, such as the characteristics of the guidelines, the care provider, the patient, and the context.

3. Tailored Action Plan: Results of the audit of nutrition practices and barriers questionnaire will be evaluated by the investigators and representatives from the Canadian Critical Care Nutrition CPGs Committee. Committee members include research personnel, intensivists, ICU nurse educators, dietitians, and experts in knowledge translation and health services research. They will be responsible for reviewing the benchmarked reports for each participating ICU, identifying the gaps between the key guideline recommendations and what is actually happening in practice, and reviewing the results of the barriers questionnaire to identify the barriers associated with adhering to these specific recommendations at each site. In collaboration with the local opinion leaders, a tailored 12 month action plan will be developed for each individual ICU.

   The specific behavioral change strategies to be implemented as part of the tailored action plan will likely include powerpoint presentations and handouts, packages of key journal articles, reminders (e.g. posters, checklists), system tools (e.g. pre-printed orders, bedside algorithms), interactive web-based tutorials, guidelines on establishing local implementation teams and creating a culture of team work. Prior to the implementation of these behavioral change strategies in the context of the before-after study, focus groups will be conducted to elicit feedback, and revisions made accordingly.

4. Audit of Nutrition Practices: The audit of nutrition practices will be repeated following the 12 month implementation period in order to evaluate changes in nutrition practices.
