Abstract
Background
Vietnam has one of the highest rates of antibiotic resistance in Asia. In 2020, the Vietnam Minister of Health introduced new legislation for the implementation of an antimicrobial stewardship program (ASP). The evidence for the effectiveness of ASP in small hospitals and hospitals located in provinces was limited compared with larger-scale and central city hospitals.
Aim
Evaluation of the impact before and after the introduction of an antimicrobial stewardship program at Dong Thap General Hospital, from 2017 to 2021.
Methods
Retrospective data was collected from June 2017 to June 2021. The impact of the ASP on changes in antibiotic use and the clinical outcome associated with the implementation of the ASP was evaluated using autoregressive integrated moving average modelling of controlled interrupted time-series analysis.
Results
There was a significant and sustained decrease in antibiotic consumption level (step change) in 2 indicators, DOT/1000PD (129.55; P<0.01) and LOT/1000PD (99.95, P<0.01), immediately after the ASP intervention. There were no statistically significant changes identified in terms of consumption with DDD/1000PD, or in the clinical outcomes. The results showed no statistically significant change in consumption trend (ramps) in all evaluated indicators. No statistically significant changes in consumption levels and trends were observed in the control group.
Conclusion
The ASP implemented in Dong Thap General Hospital from 2017 to 2021 showed a considerable influence on antibiotic consumption as indicated by the DOT/1000 PD and LOT/1000 PD during the initial stages. Moreover, controlling antibiotic consumption did not negatively impact patient outcomes.
