EFFORT Protein randomised trial

Higher protein dosing in critically ill patients with high nutritional risk

EFFORT Protein trial design and results
Design International, multicentre, pragmatic, registry-based randomised trial
Treatment High-dose protein, at least 2.2 g/kg/day
Control Usual protein dose, no more than 1.2 g/kg/day
Population 1301 analysed mechanically ventilated critically ill patients at high nutritional risk: 645 high-dose and 656 usual dose
Follow-up 60 days
Primary endpoint Time to discharge alive from hospital
Result Higher protein delivery did not improve time to discharge alive from hospital and may have worsened outcomes, particularly in patients with acute kidney injury and higher organ failure scores. Sixty-day mortality was 34.6% (222 of 642) with high-dose protein versus 32.1% (208 of 648) with the usual dose — relative risk 1.08 (95% CI 0.92 to 1.26).
Secondary endpoints 60-day mortality, outcomes by acute kidney injury and organ failure status

Delivery of higher doses of protein to mechanically ventilated critically ill patients did not improve the time-to-discharge-alive from hospital and might have worsened outcomes for patients with acute kidney injury and high organ failure scores.

How it has aged

Reverses a decade of guideline advice to push protein hard in critical illness. The signal of harm in acute kidney injury is the practically important part, and TARGET Protein has since reinforced the neutral-to-negative picture.
