Probability of anaphylaxis in patients with systemic mastocytosis
Anaphylaxis is a common feature in patients with mastocytosis. However, not all patients with mastocytosis experience anaphylaxis. A risk analysis model for anaphylaxis was translated into a clinical scoring system.

Conditional information

How this model should be used:
This risk assessment tool may provide a simple method of identifying and alerting patients with mastocytosis at high risk of anaphylaxis who would benefit from self-injectable epinephrine.

Model performance:
In the underlying study by Gülen et al (2017)1, a sensitivity of 86% (95% CI: 74.6 - 93.1%) and a specificity of 54% (95% CI: 41.8 - 65.4%) was observed in the development cohort (n=122). The corresponding postive predictive value (PPV) and negative predictive value (NPV) were 60.3% (95% CI: 49.2 - 70.7%) and 81.8% (95% CI: 68.6 - 91.2%), respectively.
