ITSU has taken the initiative to use the geographic information system (GIS) technology for mapping health facilities till the sub centre level and the catered population. GIS technology plays a vital role in strengthening the Routine Immunization and Vaccination program. The current immunization situation can be monitored through visual analyzed maps, by overlying the spatial information on the maps till the block and sub centre levels as a spatial referenced data. Mapping of health facilities with their respective cold chain points will be carried out for their catered population and a decision making model can be prepared by incorporating population statistics using the census data of different years. For health facilities and session mapping GPS (global positioning system)-enabled PDAs (personal data assistant) are used.
The following activities will be carried out using GIS technology to monitor the program at the grass root level:
- GPS-enabled PDAs will be used to create spatial database creation for all health facilities.
- A web-enabled or GUI (graphical user interface)-based system will be generated to analyze and visualize the RI data in map formats with respect to their real location.
- Mapping of session sites and sub centres and their distance from the respective cold chain points will be carried out on the GIS platform and integrated with the system to ensure the incorporation of outreach and migratory population for respective blocks and districts.
- A Network Analyst Process will be carried out for the route planning of the vaccine delivery from cold chain points to the session sites using GIS-based route planning and a query-based spatial infrastructure will be created to ensure the antigen-wise progress in the GIS domain. Technology-based micro planning will be done based on the proximity analysis using GIS and spatial data.
- The HMIS and MCTS data base will be linked with the GIS platform to create thematic maps based on different antigens.
