April 2020: The start of “surgical paediatric pearls” series this month, a reminder that the NHS is open for children during the COVID period, DKA update and frontline assessment of anorexia nervosa. Do leave comments below:
With thanks to Dr Ed Dallas, paediatric registrar, for putting together a succinct guide to eating disorders and the management of re-feeding syndrome.
Re-introduction of nutrition to severely malnourished individuals can precipitate refeeding syndrome which may result in cardiac failure and death.
The key biochemical abnormality is hypophosphataemia, due to total body phosphate depletion and a shift of extracellular to intracellular phosphate when the body changes from a catabolic state to anabolic.
The risk is greatest in the initial stages of refeeding (first week). The incidence increases with decreasing BMI and if weight loss is rapid.
Anorexia is a serious, potentially fatal disease—while refeeding syndrome can be fatal, the risk from malnutrition and ‘underfeeding’ is much greater.
– Assess using SCOFF questionnaire and Sit-up/Squat test.
– Consider differentials for weight loss in children (e.g. Malignancy, hormonal, illness)
– Risk Assessment according to Junior MARSIPAN guidelines: Clinical parameters, location of care, compulsory admission/treatment, legislation (e.g. Gillick competence, Mental Health Act)
See Summary below of what to look for and when to be concerned!
Baseline bloods: Red flags: Na+ < 130mmol/L, K+ < 3mmol/L, Phosph < 0.5mmol/L often symptomatic if phosphate <1mmol/L (range 1.3-2.1mmol/L), Glucose
ECG (look specifically for prolonged QTc)
For children, use the percentage of 50th centile BMI, not just the BMI.*
All vital signs, however, are to be checked against standardcharts for their age. Patients can be hypotensive, bradycardic, hypothermic.
*Plot BMI on growth chart. To calculate percentage median BMI:
Percentage BMI = actual BMI (weight/height2) x 100
median BMI (50th percentile) for age & gender
Treatment & Re-feeding:
Patient should be fed in as normal a fashion as possible. If this fails, NG feeds should be considered early in the admission. Make the decision within 24 hours. Specialist paediatric dietician must be involved early.
Risk from Re-feeding Syndrome can be reduced by careful monitoring and paediatric dietician input into choice of feed composition. A diet too high in carbohydrates increases the risk of re-feeding syndrome.
Consider phosphate (and other) supplementation early. Replace and titrate according to bloods which should be taken just before the supplement is given. Stores are usually replenished after 1 week but continue for at least 2 weeks. Consider long term lower dose supplementation.
Re-feeding Bloods (U&Es, LFTs, Phosphate, Calcium, Magnesium) to be taken before re-feeding, 6 hours after starting and then daily for 2-5 days, then at 7-10 days, at least until 2 weeks. Ideally, bloods to be taken just before any supplementation are given (so levels are not falsely high).
Patients should not be ‘underfed’ for fear of refeeding syndrome: consider starting at 20 kcal/kg/day, 5-10kcal/kg/day if high risk
SCOFF questionnaire for screening Anorexia and Bulimia
Shown to have 100% sensitivity and a specificity of 89% for patients with anorexia and bulimia.
*One point for every “yes”
A score of ≥2 indicates a likely case of anorexia nervosa or bulimia
Young people with an eating disorder may deny all the above, in which case it is very important to use your clinical judgement, monitor the situation and provide follow-up.
SUSS Test – see diagram below
Those who are High risk for re-feeding syndrome
Very low percentage median body mass index
Minimal or no nutritional intake for the past 3–4 days
Weight loss >15% in the past 3 months
Abnormal electrolytes prior to starting re-feeding
→ May need a more cautious approach (5–10 kcal/ kg/day starting regimen) with twice daily bloods
Paediatric dietician for specialist advice.
Correct dehydration – usually over 48 hours as too rapid correction can result in cardiac decompensation
Prescribe multivitamin and mineral supplements; consider thiamine in older children. Start any multivitamins and mineral supplementations before feeding begins (NICE CG9)
Refeeding should ideally mimic normal eating
If the patient cannot comply with a meal plan then NG considered by 24 hours. Use a daytime bolus regimen to mimic physiological eating
Consider starting at 20 kcal/kg/day. Aim for 0.5–1 kg/week weight gain.
To prevent underfeeding—aim to increase by 200 kcal/day until full nutritional requirements for weight gain are achieved (this should be within 5–7 days).
If hypophosphataemia develops, maintain rather than reduce calorie intake; consider supplementation.
Daily Re-feeding bloods (U&Es, LFTs, phosphate, magnesium) during the ‘at-risk’ period of days 2–5 initially, and at 7– 10 days (to identify late refeeding syndrome) up to at least 2 weeks
Restrict carbohydrate intake and increase dietary phosphate (eg, using milk). If NG feeding, avoid high calorie concentration feeds (high carbohydrate content increases the risk of re-feeding syndrome).
WHAT SHOULD I START DOING?
Assess nutritional status based on percentage median BMI, and not BMI alone.
Baseline clinical assessment of risk includes baseline ECG and SUSS test for weakness.
Have a low threshold for starting NG feeding and avoid an overcautious approach to re-feeding (consider starting at 20 kcal/kg/day and increasing by 200 kcal/day until nutrition is sufficient for weight gain).
Always consider re-feeding syndrome—monitor patient’s electrolytes (especially phosphate) before and during re-feeding, and assess the risk of re-feeding syndrome prior to starting feeding.
Prescribe a general vitamin and mineral supplement in younger children, and consider thiamine supplements in older children (main evidence in adults).
WHAT SHOULD I STOP DOING?
Taking an overcautious approach to re-feeding (may result in underfeeding syndrome)—patients should be receiving sufficient nutrition for weight gain within 5–7 days of re-feeding.
For patients receiving supplemental or NG feeds, avoid calorie dense feeds, which may be too high in carbohydrates and increase the risk of re-feeding syndrome.
Organisational skills problems (time management, memory, late and unfinished homework and projects)
Erratic work and academic performance
Poor sleep and other household routines
Difficulty managing finances, impulsive shopping
Compulsive addictions – sex, gambling, video gaming, exercise, eating
Frequent accidents secondary to recklessness
Speeding tickets, car and motorbike accidents
First degree relatives with ADHD
Low self-esteem, chronic under-achievement
ADHD is usually diagnosed after the age of 6 years to allow for the child to mature. Almost all children have times when their behaviour seems unacceptable and age inappropriate. However, when behaviours happen many times a week or daily, ADHD ought to be looked for. NICE guidance allows children to be treated after the age of 5 years and medication makes a huge and quick difference along with psychoeducation and behavioural management.

In the UK we often discuss our ageing population but sometimes fail to see the significant proportion of those in adolescence, between 12 – 19% of the total UK population in 20171.
Engaging this age group can be daunting for health professionals. HEADSSS is an interview prompt or psychosocial tool to use with young people. Still growing in the consciousness of health professionals (and in the letters making up its acronym) HEADS(SS) was first presented in publication in 19882. It has a reported yield of 1 in 3 for identifying concerns that warrant further investigation.
It follows a simple structure remembered by the acronym:
Education & Employment
Self-harm, depression & suicide
Safety (including social media/online)
The great news is that many studies have shown that self-assessment with HEADSSS tools before discussion (completed at home or in waiting rooms) yields equal, and in some cases more, information than conducting the assessment in person. Helpful for time-strapped clinicians and better utilisation of time for young people attending appointments.
Key tips for using HEADSSS
Greet young person first, let them introduce others
Practice discussing issues that embarrass you
Be clear in what you mean by confidentiality relating to discussion
See young people on their own routinely (whenever clinically appropriate)
Use linking phrases and questions that don’t presume:
Do you have a boyfriend/girlfriend?
Do you have someone important in your life?
Have you been in a relationship before? Tell me more…

With thanks to Geoff Ferguson, Director of the Parent Infant Centre (www.infantmentalhealth.com) for the following explanation of the Acquarone scales:
The Acquarone Detection Scales for Early Relationships are observational scales that provide a powerful tool for assessing an infant’s capacity to form relationships and a mother’s ability to respond to her infant. The scales have been developed during several decades of clinical practice by Dr Stella Acquarone, who is also the author of several books on infant development and parent infant psychotherapy and Principal of the Parent Infant Clinic. The Parent Infant Clinic is a private service but does have some subsidised places for families with limited financial resources.
There are two scales, a 25 item scale for observations of the infant and a 13 item scale for observations of the mother. In each case observations are divided into four domains: interpersonal, sensorial, motor and affect. Within each domain observers are asked to note the frequency of certain behaviours. For example, when observing ‘calling’ the observer is looking for ‘facial expressions, noises or gestures that seek to produce an affectionate response from the partner’.
A concern about the infant or the mother might be raised if a particular behaviour was never observed, perhaps showing a difficulty in relating, or was constantly observed, perhaps showing a defensive repetitiveness. The scales can be used to establish a thorough observational benchmark against which later changes can be compared.
