To optimise post-ICU nutrition through collaborative research, education and implementation, improving recovery trajectories and long-term outcomes worldwide.

Despite declining ICU mortality, many survivors experience persistent physical, cognitive and psychological impairments (PICS). Nutrition is a critical, yet under-researched, determinant of recovery across the ward, rehabilitation and home settings.

• Define and prioritise key research questions and outcome measures
• Facilitate multicentre studies and methodological alignment
• Create practical tools for intake monitoring and dosing
• Provide education for clinicians, trainees and allied health
• Engage patients and families to co-design care pathways

A post-ICU patient is any adult admitted to ICU for >48 hours, in a recovery phase lasting up to one year after first ICU discharge, regardless of readmissions or discharge destination.

GRIP operates as a not-for-profit academic consortium with a small Secretariat coordinating communications, events and member services, and domain leads steering the 10 research areas.
