Background The 7-1-7 metrics with ≤7 days for detection, ≤1 day for notification, ≤7 days to complete early response actions during public health outbreaks, enable early detection, notification, and rapid response. We evaluated the adoption, use of 7-1-7 metrics, and the bottlenecks and enablers for achieving the metrics in the public health sector of Cambodia. Methods A sequential explanatory mixed-methods design was used. A cross-sectional study using a structured checklist was employed to assess the level of adoption (26 participants) and a cohort design to assess use of 7-1-7 metrics for the public health events reported between Jan’23 and Jul’2025. A qualitative descriptive study using 6 focus group discussions and 22 key informant interviews was conducted to explore the bottlenecks and enablers in 7-1-7 adoption and implementation. Results Adoption of 7-1-7 metrics was achieved at national level and is in progress at the subnational level. Health system readiness, intersectoral coordination, capacity building, budget and resources, and digital data collection were major themes that influence adoption. Among 58 events, 26 were respiratory illnesses. The median (range) time was 6(
