Introduction A major driver of antimicrobial resistance (AMR) and poor clinical outcomes is suboptimal antibiotic use, although data are lacking in low-resource settings. We reviewed studies on systemic antibiotic use (WHO ATC/DDD category J01) for human health in Indonesia, and synthesized available evidence to identify opportunities for intervention.
Methods We systematically searched five international and national databases for eligible peer-reviewed articles, in English and Indonesian, published between 1 January 2000 and 1 June 2021 including: 1) antibiotic consumption; 2) prescribing appropriateness; 3) antimicrobial stewardship (AMS); 4) perceptions among consumers and providers. Two independent reviewers included studies and extracted data. Study-level data were summarized using random-effects model meta-analysis for consumption and prescribing appropriateness, effect direction analysis for AMS interventions, and qualitative synthesis for perception surveys.

Results Of 9323 search hits, we included 100 reports on antibiotic consumption (20), prescribing appropriateness (49), AMS (13), and/or perception (25) (8 categorized in >1 domain). The pooled estimate of overall antibiotic consumption was 110.1 DDD/100 patient-days (95%CI98.5-121.6), with ceftriaxone, ampicillin and levofloxacin being most consumed. Pooled estimates for overall appropriate prescribing (according to Gyssens method) were 33.5% (95%CI18.1-53.4%) in hospitals and 49.4% (95%CI23.7-75.4%) in primary care. Pooled estimates for appropriate prescribing (according to reference guidelines) were, in hospitals, 99.7% (95%CI97.4-100%) for indication, 84.9% (95%CI38.5-98.0%) for drug choice, and 6.1% (95%CI0.2-63.2%) for overall appropriateness, and, in primary care, 98.9% (95%CI60.9-100%) for indication, 82.6% (95%CI50.5%-95.7%) for drug choice and 10.5% (95%CI0.8-62.6%) for overall appropriateness. The few AMS intervention studies conducted to date suggested potential to reduce antibiotic consumption and improve prescribing appropriateness. Key themes identified in perception surveys were lack of antibiotic knowledge among consumers and non-prescription antibiotic self-medication.
Conclusions Context-specific strategies are urgently needed to improve rational antibiotic use in Indonesian hospitals and communities, with critical evidence gaps concerning private and informal health providers.
