The CHT’s Event Based Surveillance (EBS) functionality enables rapid capture of information about community events that are a potential risk to public health. Deployed at the community level, this functionality is designed to:
Patient reporting through traditional primary health care channels is not well suited for detecting rapidly spreading outbreaks at a community scale. Timely detection of outbreaks and important public health events can be delayed or missed when relying on individual patient data and traditional health management information systems.
Event Based Surveillance with the CHT offers opportunities for rapid deployment and measurable community impact for reportable diseases, including COVID-19. Through more timely event data reporting and analysis, the CHT provides early indicators of emerging issues to community health workers across the health system. The CHT solution offers:
|National and District Officials||Central and district offices||Desktop, laptop and smartphones||Monitor overall system and analytics regarding verified, investigated and missing cases.|
|Sub-District Investigators||Facilities or local offices||Tablet or smartphone||Investigate verified reports within 24 hours of signal report; add data to signal case.|
|CHW Supervisors||Community level, based at facilities||Smartphones and personal phones||Verify COVID-19 signals. Provide feedback and guidance to CHWs.|
|CHWs and Volunteers||Community level||Feature phones and some smartphones||Detect and report signals. Provide guidance and health education to patients and families.|
This demo illustrates a workflow that enables CHWs to use SMS to report signal codes for specific community health threats. The CHW Supervisor can then verify the initial report and, if warranted, escalate to the sub-county for investigation and follow-up. It is designed to be flexible and can be combined with other complimentary care workflows.
