\u201cPenicillin allergy\u201d is one of the most common findings in the preoperative medical history\u2014and one of the least precise. Without more specific details regarding the type of reaction, its timeline, and the affected organ system, it is impossible to determine whether an allergy actually exists or whether certain alternative medications are suitable. A structured digital medical history can specifically elicit the information needed to make a reliable assessment. <\/p>\n\n
Many patients report an \u201callergy to antibiotics\u201d without being able to specify the active ingredient, the type of reaction, or when it occurred. If this statement is accepted without further consideration, it often leads in practice to a switch to reserve antibiotics or to an allergy evaluation marked as necessary, even though both could often be avoided with a more thorough medical history. An imprecise statement is therefore not merely a minor documentation issue, but has a direct impact on perioperative medication. <\/p>\n\n
The S2k guideline \u201cDiagnosis of Suspected Beta-Lactam Antibiotic Hypersensitivity\u201d (AWMF Registry No. 061-032, DGAKI in collaboration with AeDA, GPA, DKG, \u00d6GAI, and PEG) defines what information constitutes a reliable medical history:<\/p>\n\n
This level of detail is difficult to capture in a traditional medical history form with a free-text field labeled \u201cAllergies\u201d\u2014it requires specific follow-up questions that go beyond a simple yes\/no answer.<\/p>\n\n
The guideline contradicts the long-held assumption of general cross-reactivity among all beta-lactam antibiotics: Only in isolated cases do individuals actually have an allergic reaction to all members of this class of drugs. The majority of patients allergic to penicillin can tolerate certain cephalosporins without a reaction. <\/p>\n\n
