Helpline
It is unclear whether telephone helplines improve outcomes for those at
risk of anaphylaxis because the certainty of evidence is very low
(supplement S8e). One trial with children and their families found that
a telephone helpline was associated with a clinically important
improvement on a validated food allergy quality of life scale at 12
months. There was no statistically significant difference in use of
health services for allergic events or anaphylaxis (very low
certainty).11Kelleher MM, Dunngalvin A, Sheikh A, Cullinane C,
