- Recommendation ID
- CG134/3
- Question
- Length of observation period following emergency treatment for anaphylaxis:- For how long should a person who has received emergency treatment for anaphylaxis be observed?
- Any explanatory notes
(if applicable) - Why this is important:- No studies were found that compared different observational periods or the effect of these on relevant patient outcomes. It is recommended that a cluster randomised controlled trial is conducted for people who have received emergency treatment for anaphylaxis.
The interventions for the trial should be differing time periods of observation, within the secondary care setting, ranging from 1 hour to 24 hours after symptom resolution of the index reaction. Patients should then be followed up for 7 days following the end of the observational period to determine if a biphasic reaction has occurred and the effects of any reaction. The aim is to determine whether differing periods of observation have a detrimental effect on morbidity and mortality and to gather information about resource use.
