NICE, the healthcare guidance body, has today (14 December) published a new guideline on the initial assessment and referral following emergency treatment for a suspected anaphylactic episode.

An anaphylactic episode (sometimes called an anaphylactic shock) is a severe allergic response that is a generalised or systemic hypersensitivity reaction that is characterised by life-threatening airway, breathing and/or circulation problems. Common causes of anaphylactic reaction, especially in children, includefoods such as peanuts, nuts, eggs, shellfish, milk, fish, and some seeds such as sesame. Non-food causes include wasp or bee stings, natural latex (rubber), and penicillin. A significant proportion of anaphylaxis is classified as idiopathic, in which there are significant clinical effects but no identifiable stimulus.

Because of inconsistencies in reporting anaphylaxis, and because it is often misdiagnosed, there is no overall figure for the frequency of anaphylaxis from all causes in the UK. However, available UK estimates suggest that approximately 1 in 1,300 of the population of England has experienced anaphylaxis at some point in their lives. There has also been a dramatic rise in the rate of hospital admissions for anaphylaxis. Between 1990 and 2004 they increased from 0.5 admissions per 100,000 to 3.6 per 100,000 - an increase of 700% - and there are now around 20 deaths each year in the UK from anaphylaxis (although this may be a substantial underestimate). In addition, there is considerable geographic variation in both practice and service provision, specifically in assessment after the event to confirm an anaphylactic episode or on the decision to refer after emergency treatmenti.

Recommendations from the new guideline include:

Record the circumstances immediately before the onset of the reaction to help to identify the possible trigger.
Children younger than 16 years who have had emergency treatment for suspected anaphylaxis should be admitted to hospital under the care of a paediatric medical team.
After emergency treatment for suspected anaphylaxis, offer people (or, as appropriate, their parent and/or carer) an appropriate adrenalineii injector as an interim measure before the specialist allergy service appointment.
Each hospital trust providing emergency treatment for suspected anaphylaxis should have separate referral pathways for suspected anaphylaxis in adults (and young people) and children.

Interesting article. I don't know much about anaphylaxis management in the UK so this provided a small window to their world. I like the mention of non-food sources of anaphylaxis, but I'm not sure that a significant proportion of anaphylactic reactions are idiopathic. Thanks for sharing.

Thanks Mary, but drat it, the page is now unavailable.

Not sure why they seem to put so much emphasis on age difference. Obviously young kids are pretty vulnerable, but I'd have thought they'd also be worried about heart attack in somewhat older patients.
