Knowledge
Assessment
Methods GMP
Knows the role of nutrition as therapy for active IBD SCE 1
Knows the role of dietary alteration in treatment of symptoms of IBD
e.g. low residue diet for stricturing disease
SCE, CbD 1
Knows the mechanism of nutritional deficiency in IBD, the importance
of gut preservation, and the role of nutritional support in IBD
SCE, CbD 1
Understands the circumstances when nutritional support should be
provided by enteral or parenteral routes, and to know the various
methods of delivery
SCE, CbD 1
Understands the possible methods of maximising bowel preservation
including appropriate medical therapy, endoscopic therapy and bowel
preserving surgery
SCE, CbD 1,3
Skills
Uses enteral feed as therapy for active disease in appropriate
patients, and to alter diets as appropriate to improve symptoms
SCE, mini-CEX, CbD 1
Can use enteral and parenteral nutrition appropriately to support
patients with active IBD and to prevent substantial malnutrition
mini-CEX, CbD 1
Can perform colonoscopic balloon dilatation to prevent the
requirement for resection, and to understand when to refer for
enteroscopic dilatation or for a surgical opinion
DOPS, CbD 1
Behaviours
Explains to patients and relatives the importance of nutrition as
treatment and support
mini-CEX, PS 1,3,4
Can work with the MDT to ensure all treatment decisions maximise
bowel length
CbD 1,3
Liaises with dieticians and other healthcare professionals to ensure
that all patients have appropriate nutritional support
Also...

Knowledge


Appreciates that preserving bowel length is important
Knows how to use immunomodulating or biological drugs to treat IBD
so as to maintain a maximum bowel length and avoid resections that
may result in a short bowel

Knows endoscopic and surgical techniques that avoid bowel being
resected (e g balloon dilatation and sphincteroplasty)

Knows the dietary therapies available to reduce disease and
symptoms (e g for intermittent obstruction l giving a liquid or low fibre
diet)

Skills
Appreciates that preserving bowel length is important
Can use immunomodulating or biological drugs to treat IBD so as to
maintain a maximum bowel length and avoid resections that may
result in a short bowel

Behaviours
Can empathise with and appreciate the needs of patients with IBD
Works within the multidisciplinary NST and also with the IBD nurses
and surgeons

Discuss any issue relating the disease honestly with the patient
carers friends and family

Also
Knowledge


Knows the causes of small bowel infarction
Knows the difference between arterial and venous gut infarction
Understands the problems and timing of anastomosing the small
bowel onto the colon

Knows the different methods of imaging the vascular supply to the gut
(e g CT angiography digital subtraction angiography angiograms
etc)

Skills
Is able to investigate the causes of a small bowel arterial or venous
infarction

Can identify other co-existing vascular problems
Can choose the appropriate route for nutritional support (EN or PN)
Be able to feed into defunctioned gut (fistuloclysis) when appropriate
Behaviours
Works within the multidisciplinary NST and with the vascular
surgeons and Haematologists
Appreciates there may be other co-morbidities that limit treatment
Can discuss disease-related issues honestly with the patient carers
friends and family

Also...

Knowledge


Knws the principles of normal post operative care including early fluid
management (avoiding excessive saline) and having a knowledge of
when to start nutritional support

Appreciates the reasons why surgical wounds and anastomoses can
break down

Knows the stages of development of an enterocutaneous fistula and
thus the appropriate fluid/nutritional management at each stage

Understands how complex abdominal wounds are dressed (e g
wound manager bags)

Understands what is meant by a frozen abdomen and sclerosing
peritonitis

Knows why intestinal obstruction occurs and the ways in which it can
be managed

Knows why abdominal surgery is best avoided 0- 00 days after the
last abdominal operation

Knows the principles of enhanced recovery after surgery (ERAS)
(including reducing insulin resistance and saline excess)

Skills
Can institute an appropriate investigation plan for occult sepsis
Can assess whether an enterocutaneous fistula is likely to close
spontaneously

Is able to prescribe appropriate pain relief (often with the pain team)
Can assess fluid losses and thus give appropriate fluid replacement
Appreciates the principle of later restorative surgery
Is able to arrange the appropriate tests for mapping the remaining gut
(both that is in and out of circuit)

Gives appropriate psychological care with the psychological medicine
team

Helps a patient to be physically and emotionally well so they are able
to tolerate more surgery if necessary or be able to cope at home

Can feed into defunctioned gut (fistuloclysis) when appropriate
Behaviours
Understands role of tissue viability nurses and can integrate care with
them

Explains to patients their anatomy the principles of intended
treatment and any procedures

Nutrition and Diabetes

Medical Nutrition Therapy for type 2 diabetes 1. Caloric intake (balanced with caloric expenditure) improves glycaemic control 2. Weight loss- Aim for 5-10% weight loss with Exercise (Improved glycemic control/ Weight control/ Reduction in co-morbidities (HTN, CV disease, and depression) /Improved QOL Meal planning (calorie counting/ meal replacements Consider medications (sibutramine/ Rimonabant, a selective cannabinoid type 1 (CB1) receptor blocker) Surgery if diabetes and BMI is ≥35 kg/m2. Diabetic meds: Insulin and thiazolidinediones cause weight gain, metformin and exena-tide (incretin mimetic) therapy cause weight loss. 3. Consistency in day-to-day carbohydrate intake at meals and snacks Carbohydrate counting — Usually 50% of total calories. Aim for 30-45g meals and 15-20 g for snacks. Overall < 130 g/d 4. Nutritional content A diet that includes carbohydrates from fruits, vegetables, whole grains, legumes, and low-fat milk is encouraged Saturated fat should be less than 7 % of calories and there should be minimal trans fat. Total cholesterol < 200 mg daily. Renal impairment: No CKD: Dietary protein of 15 to 20 % of calories. Early CKD: Reduction of protein intake to 0.8 to 1.0 g/kg body weight per day Late CKD: Reduction to 0.8 g/kg body weight per day High protein diets (>20 % of calories) are not recommended f Fibre intake should be > 14g/1000 calories daily Sodium intake < 2300 mg per day, or <2000 if heart failure5. Timing of meals and snacks- Insulin regimes require a consistent food intake. Oral medications are more forgiving GOALS OF NUTRITIONAL THERAPY —ABC: A1C, Blood pressure, LDLcholesterol (LDL) Consider five key aspects: Written by Dr Sebastian Zeki
