[Physicians' knowledge with regard to the timing of adrenaline administration for anaphylaxis in Japan]

Adrenaline administration is a top priority treatment for severe anaphylaxis. A survey with regard to the timing of adrenaline administration for anaphylaxis was conducted among physicians in Japan.

The survey was conducted using a questionnaire among physicians who had contributed to a nationwide survey for acute food allergy monitoring in 2011. The questionnaire comprised questions asking physicians whether they possessed registrations as an adrenaline self-injector (ASJ), and timing of adrenaline administration for anaphylaxis. Symptoms of anaphylaxis were categorized into shock or respiratory, gastrointestinal, cutaneous, or laryngeal symptoms.

A total of 674 replies were obtained from physicians, and 547 physicians were reported to be registered as ASJs. With regard to time, when patients injected themselves with adrenaline, it resulted in laryngeal (78.4%) and circulatory symptoms (64.4%), whereas when physicians administered adrenaline in patients, it resulted in circulatory (74.8%) and laryngeal symptoms (70.0%).

Japanese physicians did not necessarily understand the timing of adrenaline administration. Therefore, it is important to provide appropriate education to these physicians with regard to anaphylaxis and ASJ.
