MEED Guidance Explained: Physical Health Monitoring Standards for Eating Disorder Services

Eating disorder services are expected to work to a specific, named clinical standard for assessing and managing the physical risk that comes with severe eating disorders — and that standard has changed name. If your training materials still reference MARSIPAN or Junior MARSIPAN as the current guidance, they're out of date: both have been superseded by MEED (Medical Emergencies in Eating Disorders), the Royal College of Psychiatrists' College Report CR233, first published in 2022 and updated in December 2025.

Why MARSIPAN was replaced

MARSIPAN (Management of Really Sick Patients with Anorexia Nervosa) and its companion guidance for under-18s, Junior MARSIPAN, focused specifically on anorexia nervosa. MEED deliberately widens that scope to cover medical emergencies arising from any eating disorder, reflecting growing clinical recognition that serious physical risk isn't confined to anorexia — bulimia nervosa, binge eating disorder and other presentations can all produce life-threatening physical complications that services need a consistent framework to assess.

The traffic-light risk framework

MEED organises physical risk into a traffic-light system — green (low impending risk to life), amber (high concern for impending risk) and red (high impending risk to life) — applied across multiple clinical domains rather than a single score. Those domains include weight loss and BMI (age-adjusted for patients under 18), cardiovascular stability, hydration status, temperature, muscular function, biochemical abnormalities, disordered eating behaviours themselves, and the patient's psychological engagement with treatment. A patient can sit in different risk bands across different domains simultaneously, which is part of why MEED replaced a narrower set of anorexia-specific markers with this broader, multi-domain approach.

The specific numbers staff need to know

MEED sets out concrete physical monitoring thresholds that any eating disorder service should be training staff against: a heart rate below 40 bpm (bradycardia) is a significant concern; core temperature below 35.5°C indicates hypothermia; ECG monitoring should watch specifically for QTc interval prolongation; and electrolyte monitoring — particularly potassium and phosphate — is essential, especially during refeeding. Muscular function assessment (the Sit-Up, Squat-Stand test, grip strength, and mid-upper arm circumference) is also a named component, because muscle wasting can be present and dangerous even when other markers look reassuring.

The "normal bloods" trap

One of MEED's most clinically important messages is a warning against false reassurance: normal blood parameters can still appear in a seriously malnourished patient, and should not be read as evidence that physical risk is low. Services training staff on MEED should make this point explicit — it's a recurring factor in care failings where a patient's physical deterioration wasn't escalated because bloodwork alone looked unremarkable.

What MEED requires from services, not just individual clinicians

MEED isn't only a clinical assessment tool — it sets organisational expectations. Services are expected to maintain a genuinely multidisciplinary team covering physicians or paediatricians, specialist dietitians, nursing staff and psychiatrists; to have documented protocols covering medical stabilisation, safe refeeding, and psychiatric management as distinct but connected pathways; to provide specific staff training on eating disorder medical emergencies rather than relying on general mental health training; to have clear transition pathways between acute medical care and specialist eating disorder mental health services; and to participate in peer review networks and audit. A service that can point to individual clinicians who know the traffic-light thresholds, but has no documented organisational protocol connecting medical and psychiatric care, hasn't fully met what MEED expects.

What this means for CQC inspection and compliance evidence

Because MEED is the Royal College of Psychiatrists' current named standard, services should expect inspectors and commissioners to reference it directly rather than MARSIPAN when assessing eating disorder service quality. Training records, protocols and audit documentation that still cite MARSIPAN by name are a quick signal that a service's compliance materials haven't been refreshed — updating that terminology, and the underlying monitoring protocols behind it, is a reasonable first step for any service reviewing its eating disorder pathway.

Frequently asked questions

Does MEED apply to adult services only, or children and young people too?
MEED applies across all ages, using age-adjusted thresholds (for example, BMI centiles rather than absolute BMI for patients under 18) rather than a separate children's document — this is one of the ways it consolidates what MARSIPAN and Junior MARSIPAN covered separately.

Is MARSIPAN terminology still acceptable in training materials?
No — since MARSIPAN and Junior MARSIPAN have been formally superseded, services should update training and protocol documents to reference MEED (CR233) as the current standard.

How often is MEED guidance updated?
CR233 was first published in 2022 and was updated in December 2025, so services should check for the current version periodically rather than assuming a static document.

Physical health monitoring competency for eating disorder care is a specific, named CPD requirement. Explore Learnsignal's CPD courses to keep this training current.

Why this sits alongside, not inside, general mental health ward training

MEED-specific physical health monitoring is easy to under-resource precisely because eating disorder services are often commissioned and inspected within the wider mental health estate, using the same regulatory lens applied under the Commission's broader annual Mental Health Act monitoring. That lens is built around detention safeguards and restrictive practice, not around the specific physiological markers — refeeding syndrome risk, bradycardia thresholds, postural blood pressure drops — that MEED exists to standardise. A service can score well against generic ward safety audits while still having staff who aren't confident reading the specific physical observations MEED calls for. CPD planning should treat MEED competency as its own line item, verified separately, rather than assuming it's implicitly covered by general ward safety or Mental Health Act compliance training.
