Objectives:
Antibiotic allergy questionnaire is a useful tool for prescribing antibiotics. The objective of this study is to assess the prevalence and clinical reliability of antibiotic allergy in medical records.
Patients And Method:
Observational analysis of clinical records. Assessment of antibiotic allergy by direct interview conducted by the investigator.
Results:
610 medical records were evaluated. Antibiotic allergy was checked in 98%, mainly in medical wards. In 12 % of patients, antibiotic allergy was suspected, but after investigator interview only 5% of patients fulfilled clinical criteria for allergy. 44% of falses allergies were recorded. The most frequent cause of confusion was faint and gastric intolerance.
Conclusions:
The questionnaire about antibiotic allergy is present in almost all medical records. However its reliability is low, less than 50%. Prevalence of veritable antibiotic allergy is 5% in this study. Antibiotic allergy questionnaire in medical records is a practical tool. However periodical training about antibiotic allergy definition is necessary for nurses and medical staff.
