Red flags
- Starting full-rate feeding in a chronically starved older adult without thiamine and electrolyte monitoring precipitates refeeding syndrome — start 10 to 15 kcal/kg/day and escalate over 4 to 7 days
- A PEG request in advanced dementia needs the evidence conversation, not a booking form — hand feeding is preferred; reserve PEG for recoverable dysphagia
- Correcting hypernatraemia faster than 10 mmol/L per 24 hours risks cerebral oedema; hyponatraemia faster than 8 to 10 risks osmotic demyelination
- A nil-by-mouth order left unreviewed starves the patient and primes refeeding risk — reassess swallow and feeding every day
- Using recalled thresholds without a cited source is forbidden — verify before acting
Meet the patient
Mrs K is an 84-year-old widow admitted with a fall and a fractured neck of femur. She has lost 8 percent of her body weight in three months, her temporalis is hollow, her albumin is 28 g/L, and her MUST score is 2. The surgical team has written "diet as tolerated" and moved on. The question that decides whether she walks out of hospital is not the fracture — it is whether you notice she is starving, work out why, and refeed her without precipitating refeeding syndrome.[4][12]
Hold those three questions — is she malnourished, why, and how do I feed her safely — and the whole topic falls into place.[4]
