The excessive use of antibiotics in the United States has been well documented and is a result of the knowledge base and behaviors of not only prescribing physicians but also patients and caregivers. An antibiotic-use screening evaluation (ABUSE) was developed for each group to promote better awareness among all parties as to ways that they may be overusing antibiotics. The ABUSE questionnaires also serve as tools for confidential self-scoring evaluation of the extent of personal antibiotic misuse.
