Understanding Public Knowledge and Behavior Regarding Antibiotic Use in Indonesia

Background: Inappropriate use of antibiotics is a prominent factor contributing to the development of antibiotic resistance, which subsequently increases healthcare costs and heightens mortality rates. Objective: This study sought to evaluate the level of knowledge and behavior pertaining to antibiotic usage within the Indonesian population. Methods: This observational study was conducted in Indonesia between December 2019 and June 2020 and employed a validated questionnaire to survey 582 respondents. A comparative analysis was performed to investigate the differences in mean scores across various respondent characteristics, specifically related to their knowledge and practice regarding antibiotic usage. Regression analysis was used to identify the factors influencing the adoption of appropriate behavior in antibiotic utilization. Results: Study participants comprised 68.2% males and 31.8% females. Participants achieved an average score of 4.86 +/- 2.40 out of eight points for knowledge and behavior with an average score of 5.29 +/- 1.85 out of seven points. Approximately 57.7% and 56.0% of the respondents have knowledge and behavior scores above the average score of the total population, respectively. The findings indicated notable variations in average knowledge scores associated with educational attainment and employment status regarding antibiotic use. Similarly, differences were observed in gender and employment status concerning behavior. Regression analysis highlighted that employment status, trust in physicians, and possessing sound knowledge of antibiotic usage were significant predictors of good behavior in utilizing antibiotics. Some misconceptions were identified, such as using antibiotics to kill viruses and believing antibiotics are effective for any kind of disease. Conclusion: Less than 60% of the respondents have knowledge and behavior scores above the average score of the total population; however, there are some misconceptions regarding antibiotic utilization. This underscores the importance of implementing targeted strategies, such as health education and public health campaigns, to improve the population's understanding of the correct antibiotic use.
