Pain, Infection, Nutrition, Constipation, Hydration, Medication and Environment.

What is Delirium? According to the Royal College of Psychiatrists, delirium is a state of mental confusion that can happen if you become medically unwell.  It is also known as an 'acute confusional state'.

 Medical problems, surgery and medications can all cause delirium. It often starts suddenly and usually lifts when the condition causing it gets better. It can be frightening – not only for the person who is unwell but also for those around him or her.

PINCHME

  • Pain - Does your patient have uncontrolled pain?
  • Infection - Are they known to have a source of infection or could an infection be likely?
  • Nutrition - Does your patient have adequate nutrition? Could they be at risk of refeeding syndrome?
  • Constipation - When did your patient last have their bowels open? Could they be constipated?
  • Hydration - Are they drinking enough? Does that patient require supplementary fluids? Dehydration and over-hydration can cause changes to electrolytes.
  • Medication - Could any medication be causing the delirium? A full review of medication should be undertaken by a doctor.
  • Environment - Is it too loud? Is it too hot? Too bright? Ask your patient if anything around them is causing distress.

If someone becomes suddenly confused, they require an urgent medical review and to treat delirium effectively you need to identify and treat the cause.
