Description of intervention(s) / exposure
Other interventions - Supplemental parenteral nutrition

No Intervention: Standard Nutrition Arm - In ICU:
After enrolment, patients allocated to the standard nutrition therapy (control) group will commence or continue nutrition via an enteral tube to a target rate according to unit protocol including the use of promotility agents and the placement of nasojejunal feeding tubes if required.
PN will only be used if the above methods have been attempted, or an absolute contraindication to EN develops.
Unless there is specific indication for a compounded PN solution, the PN used in the standard care group will be the same as used in the intervention arm.
After ICU:
Nutrition management will be as per usual site management at that hospital.
Nutrition intake amounts will be recorded 3 times per week using provided study documents and assessment tools.

Experimental: Intensive Arm - Intervention
In ICU:
Supplemental PN will be commenced within 2 hours of randomisation. The starting dose of PN will be determined by the amount of energy received in the 24 hours prior to randomisation
The need for the intervention will be based on the adequacy of nutrition provision from both PN and EN and assessed daily until ICU discharge
If there is an actual or anticipated interruption of EN for greater than 2 hours the PN must be run at 20 kcal/kg calculated body weight until EN is recommenced. After the interruption, EN should be recommenced as per local protocol.
After ICU:
An intensive nutrition intervention will be provided on the ward in the intervention group. This will include daily review from dedicated study dietitians and a clearly protocolized hierarchical management plan which reflects best practice clinical management.

Key exclusion criteria
Exclusion criteria

Patients will be excluded if:

- Both EN and PN cannot be delivered at enrolment (i.e. either an enteral tube or a

- Death is imminent in the next 96 hours

- There is a current treatment limitation in place or the patient is unlikely to survive
to 6 months due to underlying/chronic illness

enteral route in the last 24 hours

- Dialysis dependent chronic renal failure

- Suspected or known pregnancy

- Product contraindication

- The treating clinician does not believe the study to be in the best interest of the
patient

Summary
Brief summary
Despite the widespread use of nutrition therapy, no large scale randomized controlled trials
(RCTs) have demonstrated positive outcomes with delivery of nutrition therapy early in
critical illness, with some showing no effect with delayed nutrition or even harm.

There are several possible reasons for the lack of observed benefit from RCTs to date;
interventions have been short in duration (usually 3-10 days after intensive care unit (ICU)
admission), perhaps applied at the incorrect time in regards to the patients metabolism and
recovery, do not consider the patients nutrition risk, and have not addressed what happens to
nutrition intake post ICU in critically ill individuals. This may explain why RCTs to date
have not observed any positive associations with the delivery of nutrition; our focus to date
may have been on the wrong stage of illness. A future study is thus urgently needed, which
addresses the deficiencies in current RCTs by optimizing nutrition delivery for the whole
hospital stay and collecting meaningful clinical, process and outcome data, which will
potentially inform a larger trial of a similar nature.

This initial study aims to determine whether optimization of energy using a pre-tested
supplemental parenteral nutrition (PN) strategy in the Intensive Care Unit (ICU) and an
intensive nutrition intervention in the post ICU period will deliver more total energy than
standard nutrition care during hospital admission in a group of critically ill patients with
at least one organ system failure.
