Goal - Accurate and open baseline health facility data that lives in OpenStreetMap Key activities: Support Human Centered Design to drive the development of the data Enable stakeholders in the health cluster to share health facility data to OpenStreetMap Support collaboration between national health agencies and field validation teams Connect multiple data streams to build higher quality data When a natural disaster or disease outbreak occurs there is a rush to establish accurate health care location data that can be used to support people on the ground. This has been demonstrated by events such as the Haiti earthquake and the Ebola epidemic in West Africa. As a result valuable time is wasted establishing accurate and accessible baseline data. healthsites.io establishes this data and the tools necessary to upload, manage and make the data easily accessible. Healthsites.io, uses OpenStreetMap (OSM) as its data store, and provides a collaborative platform to enhance health facility data quality through an open science approach. By enabling community contributions and validation OSM allows stakeholders to update and verify geospatial data, ensuring it is accurate, up-to-date, and reflective of real-world conditions. This open model fosters a global network for continuous data improvement, supporting better health system planning, emergency response, and public health decision-making. A data collaborative The collaborative is a semi-formal network that identifies and shares baseline health facility data. It works to identify data gaps and supports stakeholders with sharing and the use of data especially for decision-making. Crucially, validated data is saved to OpenStreetMap which means that successive projects are able to benefit from the work even when programs end. Use cases Epidemic Preparedness - Accurate health facility data is a vital asset when responding to outbreak events. Support for disaster response - A baseline of health facility data is a vital asset of first responders. Support for immunization programs - Accurate health capacity data supports immunization planning on the national scale. Maternity health - Updated maternal health services support midwives and pregnant women Health capacity planning - Understanding the current capacity and identifying any gaps or deficiencies. Support for Social entrepreneurs - Developing an enabling environment for entrepreneurs focused on improving health outcomes Alignment with the Global Funds COVID-19 Response Mechanism (C19RM) Intervention & Key activities: Develop or update georeferenced master lists of health facilities (public and private) Optimize outreach activities to ensure all communities are reached Establish geospatial governance Establish GIS technical capacity with OpenStreetMap focused training programs
