Anaphylaxis: a one-year survey on Medical Emergency Service in Liguria (Italy).

Anaphylaxis is a severe, life-threatening, generalized or systemic hypersensitivity reaction. The diagnosis is mainly based on clinical ground. This study aimed at evaluating the records of phone calls and medical visits for anaphylaxis occurred in Region Liguria during 2013. The phone call is managed in each headquarter, and classified according to a level of care intensity and a presumed level of criticality, according to established criteria. Criticality is then re-evaluated (detected criticality) at the end of medical visit, following the same score adding the black code defining died patients. Most of the phone calls (553) to the MES were recorded in summer (37.4%). Anaphylaxis was confirmed in about half of patients. There was a fair agreement between presumed and detected criticality (k=0.322, p<0.001). In addition, 530 patients (95.8%) were transported to Emergency Room. In conclusion, the present study shows that anaphylaxis represents a serious and relevant medical problem in the general population at any age, and should always be carefully managed.
