Non-compliance with therapeutic guidelines represents a potential public health risk, given that it contributes to bacterial resistance. One of the strategies used to improve compliance to such guidelines is to provide the patient with better information in written form. The objectives of the present investigation were the following; To evaluate the influence that written information, provided by the community pharmacist, has on compliance with antibiotic therapy, to verify the consequences of degree of compliance on patient health, and to discover other factors influencing patient compliance. The experimental study was carried on patients that attend a community pharmacy for antibiotic prescriptions. Members of the control group were given information in verbal form only, while members of the experimental group were given the same information in both verbal and written form. The degree of compliance was determined through telephone interviews, carried out the day after having finished treatment. 214 patients completed the study. A 14% increase in compliance among members of the experimental group was achieved. Patients that had completed treatment, had a better perception of their own health than those that had not. Another factor found to have a significant influence on compliance was the number of daily dosages. In conclusion, the written information provided by the pharmacist improves therapeutic compliance. Therapeutic compliance improves patients’ perception of their state of health. The number of daily dosages also have an influence to bear, but contradict appropriate antibiotic administration policies.
