Community-based surveillance programme evaluation using the platform Nyss implemented by the Somali Red Crescent...

Area of Science:

• Public Health
• Epidemiology
• Health Surveillance Systems

Background:

• Community-based surveillance (CBS) implemented by Somali Red Crescent Society (SRCS) in Somaliland aims to mitigate epidemic risks.
• The program strengthens community-level early warning and response, crucial for areas with weak public health infrastructure.
• SRCS volunteers utilize SMS reporting via the Nyss platform for disease signal transmission.

Purpose of the Study:

• To evaluate the effectiveness and impact of the community-based surveillance (CBS) program.
• To assess stakeholder perceptions and acceptance of the CBS methodology.
• To identify areas for improvement in the surveillance system.

Main Methods:

• A retrospective observational mixed-methods study was conducted.
• Routine CBS data from Awdal and Togdheer regions in 2021 were analyzed.
• Qualitative interviews were held with key stakeholders.

Main Results:

• Stakeholders recognized the CBS program's utility in preventing, detecting, and responding to outbreaks.
• High percentages of signals were escalated: 83% in Awdal and 97% in Togdheer.
• The program demonstrated simplicity, flexibility, and high stakeholder acceptance, though alert outcome recording requires improvement.

Conclusions:

• Community-based surveillance (CBS) effectively supports early warning and response for diverse public health threats.
• Enhanced documentation of alert outcomes is necessary for precise sensitivity evaluation.
• A participatory approach and digital tools like the Nyss platform are vital for successful CBS implementation.
