Area of Science:

• Global Health
• Health Systems Strengthening
• Public Health Interventions

Background:

• Childhood illness care-seeking is crucial for reducing mortality.
• Ethiopia's Health Extension Program aims to improve primary healthcare access.
• Evaluating complex interventions requires understanding implementation fidelity.

Purpose of the Study:

• To explore the implementation process of the 'Optimising the Health Extension Program' intervention.
• To identify barriers and facilitators to the intervention's successful rollout in Ethiopia.
• To assess the fidelity of intervention activities and their impact on service utilization.

Main Methods:

• Mixed-methods approach combining fidelity analysis and qualitative interviews.
• Pragmatic trial comparing intervention and control districts.
• Thematic analysis of 39 implementer interviews and fidelity assessment of 31 intervention activities.

Main Results:

• Intervention implementation was significantly delayed, with only 19% of activities achieving high fidelity in the first phase.
• Key challenges included intervention and system complexity, competing health priorities, and inadequate supervision.
• No evidence of increased service utilization for childhood illnesses was found.

Conclusions:

• Evidence-based health interventions must align with national priorities and existing health systems for sustainability.
• Realistic timelines and strengthened district health teams are essential for effective grassroots implementation.
• Addressing complexity and ensuring consistent support are critical for future health program success.
