Investigation of Antibiotic Use at a Dental Teaching Hospital in Yogyakarta, Indonesia: A Review from Guidelines

Abstract

Objective: To investigate prescription of antibiotics by dental practitioners at a dental teaching hospital in Yogyakarta, Indonesia, and to establish whether it conforms to major guidelines. Methods: A cross-sectional study of adult outpatients’ medical records was conducted in order to scrutinize antibiotic prescriptions. The results were compared with recommendations in four published guidelines. Results: Dental practitioners prescribed a wide range of antibiotics to treat 121 diagnoses. Amoxicillin (78.8%) was most commonly prescribed, followed by clindamycin (9.9%), metronidazole (5.0%), and lincomycin (2.1%). Among all prescriptions, 79.5% were for generic antibiotics. The most common diagnoses were dental pulp gangrene followed by dental pulp necrosis (26.7% and 8.8%, respectively). According to guidelines-1 through-4, the percentages of antibiotic prescriptions that were evaluated as appropriate for the reported diagnosis were 15.1%, 7.2%, 7.5%, and 16.3%, respectively. However, 9.9%, 84.0%, 83.7% and 67.8% of prescriptions could not be classified as appropriate or inappropriate because the respective guidelines neither listed the antibiotic nor gave statement regarding appropriate indications. Conclusion: Our results suggest that significant inappropriate antibiotic prescribing occurred at a dental teaching hospital in Yogyakarta, Indonesia, according to major antibiotics guidelines. However, the four guidelines failed to list some antibiotics, failed to list indications for prescription in some cases, and were inconsistent in their recommendations. There is a need to introduce specific institutional guidelines. Our findings should be helpful for developing public health policy guidelines to minimize inappropriate antibiotic prescribing at dental hospitals.
