1. Introduction to geospatial data management and technologies for PHDs
Kampong Cham
30 January - 1 February 2018

2. Summary of day 1
We went through the concepts and the components of a good thematic map
We described the process behind the making of a good thematic map
We talked about compiling good geospatial data after having defined the data specifications and the ground reference
We looked at the different ways to extract or collect geospatial data
We used Android phones and GPS essentials to take geographic coordinates in the hotel compound ??
Any questions? 2

3. Agenda for day 2
Talk about the concepts of master lists and common geo-registry 3

5. The concept of master list
Definition: The authoritative (unique), standardized, complete, up-to-date and uniquely coded list of all active records for a given object
Health Facility master list (or Master facility List): The authoritative, standardized, complete, up-to-date and uniquely coded list of health facilities for a given country (can also contain the contact details of each facility)
Administrative divisions master list: The authoritative, standardized, complete, up-to-date and uniquely coded list of all the administrative divisions in a given country and this down to the lowest level of desegregation
Patients master list: The authoritative,… 5

6. The concept of master list
Key characteristics of a health facility master list:
1. Cover the core set of fields that would allow to uniquely identify, define, geographicaly locate and, when appropriate, contact each active record in the master list;
2. Originate from the governmental entity officially mandated to develop and maintain such master list (unique);
3. Be complete and up-to-date (updating mechanism in place, validity time stamp);
4. Contain an official and unique Identifier (ID) for each record;
5. Make the link with other master lists in order to describe the geographical and hierarchical relationships between the objects (e.g. by including the name and unique code of administrative divisions in the health facility master list) 6

7. The concept of master list
Benefits include but are not limited to:
Allowing more comprehensive integration of geography and time across the HIS as well as the whole data lifecycle, therefore allowing for a more systemic approach to solving public health problems.
Supporting the implementation of programs that are heavily dependent on geography and time for their implementation and success
Improving data quality across its six dimensions (completeness, validity, timeliness, uniqueness, accuracy, consistency1).
Reducing duplication of efforts and therefore cost by maintaining only one authoritative set of lists instead of several ones.
Supporting interoperability and collaboration across partners, ability to further promote innovation and data use.
Supporting a more effective use of the visualization and analytical power offered by Geographic Information Systems (GISs).
Key to proper information management
There should only be 1 master list used across all programs in a given country! 1 7

8. The concept of master list
Some use cases:
Malaria elimination - In reactive case detection, when a positive malaria case is diagnosed in a health facility; there is a need for the case investigation team to not only being able to contact and visit the facility in question but also the place of residence (village) of the patient for further investigation, intervention and monitoring activities through time -- including for foci investigation. Ideally, the information collected in the case investigation form would be based on / informed by master lists and would be captured in the Malaria Management Information System.
Health coverage assessment - Improving health coverage throughout a country requires having a good picture of the population distribution down to the village level in order to make sure that the whole population is being covered by the catchment areas of the existing health facilities. A complete, up-to-date list of villages with the indication of their location and associated population figures is critical in this regard.
Health service delivery - Once the health coverage plan has been developed, the appropriate resources (human, equipment, financial) need to be attached to each health facility in order to ensure a cost effective delivery of health services. 8

9. The concept of registry
Definition: Central authority to collect, store and distribute an up to date and standardized master list.
In other words, a registry can be understood as the IT solution that allows storing, managing, validating, updating and sharing a master list while the master list is itself the standardized data stored in that solution.
Example of the health facility registry of the Department of Health of the Philippines: 9

10. The concept of registry
Benefits include but are not limited to:
Improving the ability for governing bodies to simultaneously and more easily manage maintain, update and share master lists as a foundational element of the Health Information System (HIS).
Facilitating the capture of the source and date of data collection associated to each bit of information stored in the master list, as well as the tracking of changes being implemented for better accountability
Improving data quality across its six dimensions (completeness, validity, timeliness, uniqueness, accuracy, consistency1).
Enhancing ability for systems to evolve and grow over time by leveraging collaborative, shared, and interoperable services around geospatial data. 1 10

11. The Concept of Common geo-registry
“Having up-to-date master lists (see glossary of term of definition) populated with these core geographic objects is not alone sufficient. There is still a need for a technology solution -- a common geo-registry -- to simultaneously host, maintain, update and openly share these master lists and relationships, together with their associated data, including geography stored in a Geographic Information System (GIS) readable format.”
Need to:
include health facilities, administrative divisions and villages
cover different type of roles 11

12. The vision Passing from this… …to this
Each information system is using a different geography and does not allow benefiting from the power of geospatial data and technologies
All the information systems use the same geography which does not only reduce duplication of efforts but also allow using geography as a common neutral integrating platform across programs
Common geo-registry: Registry containing the master lists for all the geographic objects core to public health 12
