简要总结
The primary research question: In critically ill patients with nutrition 'risk factors', what is the effect of providing combined EN/PN to the group prescribed a higher dose (≥2.2 grams/kg/day) of protein/amino acid administration compared to a low group prescribed ≤1.2 gram/kg/day (EN only) on patient's functional recovery as measured by 6-minute walk distance just prior to hospital discharge? The hypothesis: Compared to a control group reflective of usual care prescribing practices and an EN only approach, the administration of a higher dose protein/amino acids using EN and PN to nutritionally high-risk critically ill patients will be associated with improved functional outcome.
详细描述
Positive, neutral, or negative, the results of the EFFORTcombo study will inform the clinical practice in ICU settings around the world. If positive, because of the pragmatic, multicentre nature of this trial, results will be broadly applicable to all critically ill patients worldwide. If the results are negative, it will be ensured that patients no longer receive high-dose protein/amino acid admixtures or possibly, combined EN/PN.
As it relates to critical care nutrition practice in general, there is a long history of practice-changing initiatives. A process of synthesizing (in the form of evidence-based clinical practice guidelines) and disseminating best practice ideas (in the form of web-based repository of tools and information [see www.criticalcarenutrition.com\]) was established.
Over the past several years, this program of research with leaders of the American Society of Parenteral and Enteral Nutrition (ASPEN) and this specific protocol at the annual Clinical Nutrition Week with society leaders, researchers, and the clinical nutrition community at large has been discussed. Partnership with ASPEN will further facilitate both, recruitment initiatives and, importantly, the knowledge translation initiatives. These efforts will increase the likelihood of the uptake of EFFORT results across the world.
This study has both the potential to answer a high-priority clinical question and also transform the new approach in clinical nutrition research. It further represents a unique collaboration between ASPEN, its global partners, and the Clinical Evaluation Research Unit, a methodological support center based in Kingston, Ontario, Canada and managed by Dr. Daren Heyland. If successful, this type of collaboration sets an important precedent for how this community may approach additional research questions related to clinical nutrition. Nested within this larger volunteer-driven registry trial, the aim is to complete a significant sub-study that will establish the role of combined EN/PN in these nutritionally high-risk patients. This protocol pertains to the specifics of this sub-study of combined EN/PN. At the end of the trial, the data from this sub-study will be merged into the results of the overall parent EFFORT Trial (where data points are similar).

入选标准
- •≥18 years old;
- •Expected to remain mechanically ventilated for an additional 48 hours from screening;
- •And have one or more of the following risk factors that make them at high nutritional risk:
- •Low (≤25) or High BMI (≥35)
- •Moderate to severe malnutrition (as defined by local assessments). We will document the means by which sites are making this determination and capture the elements of the assessment (history of weight loss, history of reduced oral intake, etc.).
- •Frailty (Clinical Frailty Scale 5 or more from proxy)
- •Sarcopenia (SARC-F score of 4 or more from proxy)
- •From point of screening, projected duration of mechanical ventilation >4 days
排除标准
- •>96 continuous hours of mechanical ventilation before enrollment
- •Expected death or withdrawal of life-sustaining treatments within 7 days from screening
- •The responsible clinician feels that the patient either needs low or high protein
- •Absolute contraindication to EN
- •Severe metabolic disorders including electrolyte disorders, uncontrolled hyperglycemia, hyperlipidemia, hypophosphatemia.
- •Severe chronic liver disease (MELD-score >20) or acute fulminant hepatitis.
- •Metabolic disorders involving impaired nitrogen utilization
- •Not ambulating independently prior to illness that lead to ICU admission (use of gait aid permitted)
- •Lower extremity injury or impairments that prevents them walking prior to hospital discharge (e.g. amputation, knee/hip injury)
- •Pre-existing cognitive impairment or language barrier that prohibits outcomes assessment
- •Pre-existing primary severe systemic neuromuscular disease resulting in severe weakness pre-ICU (e.g., Guillain Barre)
- •Intracranial or spinal process affecting motor function
- •Patients in hospital >5 days prior to ICU admission
