Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention group (20 hour protocol) participants will receive prescribed amounts of enteral nutrition following a revised protocol that includes compensatory increase in feeding rates over a set period of 20 hours a day and then fasted for a set period of 4-hours each day.
The prescribed amount given is based on the individual's nutritional assessment and estimation of of the energy and protein requirements . These requirements are calculated using predictive equations as is the common practice by dietitians
The overall duration is a maximum of 12 days or till patient is discharged from the ICU whichever is sooner.

The 20 hour feeding protocol (Intervention group) involves running the prescribed amount for each patient as a continuous infusion for 20 hours per day followed by 4 hours of fasting Example : If a patient's requirements are 1800 calories and the amount prescribed is 1800 ml formula over 24 hours , the infusion will run at a rate of 90 ml /hour (90 ml x 20 = 1800 ml per day)

Comparator / control treatment
Control group (24 hour protocol) participants will receive prescribed amounts of enteral nutrition following the current 24 hour feeding protocol.
The 24 hour feeding protocol (Control group) involves running the prescribed amount for each patient as a continuous infusion for 24 hours per day . Example : If a patient's requirements are 1800 calories and the amount prescribed is 1800 ml formula over 24 hours , the infusion will run at a rate of 75 ml /hour (75 ml x 24 = 1800 ml per day). There is no fasting period..

Outcomes
Primary outcome [1] 287278 0
Adequacy of enteral nutrition (Amount of calories and protein received by patients versus amounts prescribed per day by the dietitian), received from enteral nutrition over the first 12 ICU days (or lesser if length of stay <12 days)
Timepoint [1] 287278 0
From the first day of study , daily audit of enrolled participants' charts for first 12 ICU days (or lesser if length of stay <12 days)
Primary outcome [2] 287279 0
Acceptability and safety of the revised feeding protocol
Staff satisfaction survey
A questionnaire will be distributed to the nurses, doctors and dietitians The secondary outcome of this pilot study is the feasibility of the new feeding protocol as judged by a questionnaire that evaluates their opinion of its safety and acceptability. The acceptability of each the novel parts of the feeding protocol and the overall protocol uses a scale where 1 = totally unacceptable and 10 = totally acceptable. This evaluation questionnaire will be administered to all bedside nurse involved in caring for study patients at the end of each nursing shift during the study period and to all medical staff. A minmum of 50 % response rate is anticipated.

Safety endpoints that will be measured are 1. Episodes of reflux, regurgitation or vomiting documented on nursing charts Frequency of diarrhoea (Stools > 300ml liquid per 24 hours), Episodes of high gastric residual volumes ( > 250 ml per 4 hours Ventilator associated pneumonia documented by medical staff, patient positioning daily: measured by researcher daily on rounds,
Management of risk factors or events

All critically ill patients are at risk of developing the above signs and symptoms while on Enteral Nutrition . ICU Standard protocols are followed to manage these conditions for ALL patients. The same protocols will be followed for the study patients.

In addition, two physicians independently will review the charts of all enrolled patients to determine whether episodes of vomiting, regurgitation, macroaspiration (visually noted gastric secretions when suctioning the endotracheal tube), and ventilator-associated pneumonia had occurred. Pneumonia is defined using a definition and process that is standard practice for the ICU doctors .This would determine if there were any undetected serious adverse events related to the nutritional management of the patient and whether the prescription hourly target rates was appropriate and this will be checked off on the data forms. At the discretion of the two physicians and /or the medical team the patient may be discontinued from the study

Secondary outcome [3] 298328 0
Participants will undergo: Quality of Life assessment with a validated EuorQol 5D (EQ5D) The EQ-5D is a global quality-of-life questionnaire that assesses five domains: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has three levels of severity; no problem to severe problems. The second part of the EQ-5D consists of a vertical visual analogue scale (VAS), where 0 represents the worst imaginable health status and 100 represents the best imaginable health status.
Timepoint [3] 298328 0
At two time points: once on the first day that they are able to do so face-to-face, and the second time through telephone assessments 60 days from the date of admission to ICU (if subjects are survivors).

Key exclusion criteria
Contraindicated for enteral nutrition for the first 72 hrs of ICU admission (inaccessible or non-functioning gastro-intestinal tract) ; patients on other forms of nutrition support ( oral or parenteral ) either exclusively or in combination with EN, discharged from the ICU less than 72 hours of ICU admission, moribund patients not expected to survive, patients who are not intubated or who receive mask ventilation ,

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients meeting the study inclusion criteria will be identified by the principal investigator. Persons responsible (eg. family) will be approached for consent to participate in the trial. Patients will be randomly allocated to a control arm ( current feeding protocol) or to an intervention group (revised feeding protocol) using a permuted block randomisation approach. The allocation sequence will be generated by an computerised random number generator which will then be transferred into concealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer program will be used to generate the permuted block random number sequence.
Masking / blinding
Blinded (masking used)

Intervention assignment

Other design features
Criteria for discontinuation: Patients likely to develop contraindications for enteral nutrition (inaccessible or non-functioning gastro-intestinal tract) during the period of study, patients considered to be at a high risk of experiencing an adverse event as determined by the Medical staff during the period of study,
