Severe floods and landslides that struck Aceh, North Sumatra and West Sumatra in late 2025 exposed both the strengths and gaps in Indonesia’s health emergency response, prompting a nation-wide effort to strengthen preparedness for future crises. In the early phase, the scale and speed of the crisis challenged coordination, data systems and surge capacity.
To assess the response, the World Health Organization (WHO) Indonesia supported the Ministry of Health’s Center for Health Crisis in conducting a multi-stakeholder after-action review (AAR). The review brought together government agencies, health sub-clusters, NGOs, and partners.
“The AAR is a critical process for strengthening our collective response capacity,” said Agus Jamaludin, Head of the Center for Health Crisis at the Ministry of Health. “It provides valuable lessons not only for the Health Crisis Center but also for all stakeholders involved and serves as an important reference for improving future responses across regions.”

Through structured discussions across four pillars – leadership and governance, information-based decision-making, service delivery and resource management – the AAR identified several strengths. These included the rapid mobilization of national surge capacity, such as health reserve workforce (tenaga cadangan kesehatan) and emergency medical teams (EMT) and the continued provision of essential health services in affected areas.
At the same time, the review highlighted challenges. Among them were uneven functionality of Health Emergency Operation Center (HEOC), fragmented early data reporting and reactive logistics deployment. The findings informed five strategic priorities for strengthening the system, including HEOC standardization, integration of the One Crisis Data system, establishing disaster-resilient hospitals and reforming surge capacity mechanisms.
The AAR demonstrates that Indonesia’s health emergency response has strong foundations but requires system-level strengthening to shift from reactive to proactive preparedness. By mainstreaming the strengths and recommendations identified, Indonesia can build a faster, more coordinated and more resilient health system – better equipped to protect communities during future crises.
