Children with peanut allergy are often provided with adrenaline (epinephrine) in case of a severe reaction. The probability of a life threatening reaction is low, however, and the criteria for provision are controversial. How should the costs and benefits be balanced?

Dylan, a 20 month old boy, was referred to a paediatric allergy clinic for assessment of his peanut allergy. At 12 months of age he developed facial contact urticaria to peanut butter, which spontaneously resolved without respiratory or other symptoms. Since then, he has not had further reactions or eaten peanuts, although the rest of the family often eat peanuts and nuts. Dylan is regularly cared for by his grandparents and does not attend a childcare centre. His skin prick tests show a 9 mm ( 3 mm is considered positive) reaction to peanut.

The doctor recommended that he continue to avoid peanuts and be reviewed annually with skin prick testing. If the results remain positive without other clinical reactions, Dylan will be considered for a formal food challenge when he starts school. An emergency adrenaline (epinephrine) autoinjector (self or carer administered) was not recommended. Dylan's mother said, "I had heard about [autoinjectors] so I was waiting to hear what the specialist would say. I suppose that if you had to, you would give it, but I just can't see it. I hate seeing him have needles for any reason."

Jarred is 23 months old and attended the same clinic. At 9 months of age, peanut butter touched his face and he developed local urticaria and lip and periorbital swelling without respiratory or systemic symptoms. His parents took him to the local hospital, where he was placed on cardiorespiratory monitors and given two adrenaline injections. He was then seen by a paediatric allergist, who prescribed an adrenaline autoinjector. Since then he has avoided peanuts and has not had further reactions. Peanuts have been removed from the household and the family's diet. After Jarred's enrolment, the childcare centre he attends two days a week completely banned peanuts, nuts, and any foods labelled "may contain nuts."

At this consultation, skin prick tests showed a 9 mm reaction to peanut. Jarred's parents were advised that he should continue to avoid peanuts. Although his mother was informed that the risk of death was extremely low, she wished to continue Jarred's autoinjector prescription: "My biggest fear is that he could be having a reaction and he can't tell us... the autoinjector allows me to feel more in control... it's a safety net so I'm not totally helpless."

It will be no surprise to clinicians that patients with similar clinical features can end up being managed differently. Variation in medical practice may be deemed appropriate or inappropriatew1 and stems from many sources, some of which are unavoidable. Underlying the decisions of individual doctors and patients is the inherently uncertain nature of medical knowledge. In our example of childhood food allergies, the uncertainty is given a potent twist by a remote but dreaded outcome
