Prevalence and Characteristics of Antibiotic Allergy in Patients Over 65 Years in A Long-Term Care Setting

Introduction: Antibiotic allergy is a commonly reported condition, particularly among older adults, and may contribute to inappropriate antibiotic prescribing and adverse health outcomes. This study aimed to evaluate the prevalence and characteristics of suspected antibiotic allergy in patients over 65 years residing in a long-term care facility, Centre Sociosanitari Colisee Dolors Aleu (Barcelona), and to assess whether reported allergies were confirmed through allergological evaluation or based solely on clinical suspicion.
