Scientific title
Refeeding risks in patients requiring nutrition support: a twin centre double-blind randomised controlled trial of parenteral nutrition support
Acronym
Study hypothesis
We will conduct a randomised controlled trial to investigate the levels of nutrition support that minimise the dangers of refeeding syndrome in moderately/severely malnourished patients, while providing maximum nutrition for those in need. To do this we will conduct a twin-centre, prospective, randomised, controlled, double-blind trial of both physiological and biochemical markers of refeeding syndrome and clinical outcomes in patients needing intravenous nutrition support who, despite being at moderate or higher refeeding risk according to NICE defined criteria, are commenced at close to NICE recommended cautious levels, or more generous feeding levels (close to estimated requirements).

Eligibility
Participant inclusion criteria
1. All consenting patients (minimum 18 years old, either sex) who require intravenous nutrition as assessed by the Southampton University Hospitals NHS Trust and the Royal Berkshire NHS Foundation Trust Nutrition Support Teams
2. Patients who do not require specialised parenteral nutrition regimens to meet their clinical needs
3. Patients who are at moderate or high risk of refeeding syndrome as defined by:
3.1. Moderate risk (one of the following criteria):
3.1.1. Body mass index (BMI) less than 18.5 kg/m^2
3.1.2. Unintentional weight loss greater than 10% in 3 - 6 months
3.1.3. Very little or no food intake for greater than 5 days
3.2. High risk (one of the following criteria):
3.2.1. BMI less than 16 kg/m^2
3.2.2. Unintentional weight loss greater than 15%
3.2.3. Very little nutritional intake for greater than 10 days
Or
Two of the following lesser criteria:
3.2.4. BMI less than 18.5 kg/m^2
3.2.5. Weight loss greater than 10%
3.2.6. Very little nutritional intake for greater than 5 days

Target number of participants
Planned sample size: 230; UK sample size: 230
Participant exclusion criteria
1. Patients at very high risk of re-feeding syndrome (two or more of the NICE criteria: BMI less than 16 kg/m^2, recent weight loss greater than 15% body weight within 6 months, greater than 10 days with no nutritional intake) or patients with a BMI less than 14 kg/m^2)
2. Levels of K/Mg/PO4 below lower limit of normal (LLN) range from the SUHT chemical pathology laboratory prior to feeding
3. Patients with oral nutritional intake
4. Intensive care patients (who often receive variable levels of additional enteral tube feeding)
5. Patients weighing 80 kg or more giving them an estimated energy requirement above 2400 kcal/day (as we feel giving patients more than 2400 kcal/day poses too great a risk)
6. Patients with pre-existing diabetes mellitus
7. Patients unable to give informed consent to take part
