Smartphone app for laypeople
It is unclear whether smartphone educational apps for people at risk of anaphylaxis affect outcomes because the certainty of evidence is very low. In one trial 38% more laypeople who used a smartphone app to guide them through using an autoinjector undertook all steps correctly compared to those who received standard autoinjector instruction (CI not reported, statistically significant, very low certainty, supplement S6c).11Hernandez-Munoz LU, Woolley SI, Luyt D, Stiefel G, Kirk K, Makwana N, Melchior C, Dawson TC, Wong G, Collins T, Diwakar L.
