The app is designed to streamline the enumeration and stati stical sampling process and can be used in areas with limited internet and cell phone connectivity. \n\nWhy is it important?\nThe 2018 World Health Organization guidance for vaccination coverage cluster surveys recommends that routine immunization coverage surveys use probability sampling method s and generally use census data derived from enumeration areas as the samp ling frame. \n• Existing process: As many countries lack up-to-date popu lation sampling frames\, teams are often sent to map and list households ( HHs) in enumeration areas using a set of devices. Upon returning to an are a with wifi\, data from each device must be uploaded to a server\, collate d\, and reviewed to ensure that no sections of the enumeration areas (EAs) were missed during mapping. Once the sampling frame is verified\, a sampl e of HHs can be drawn and another team is deployed to navigate to selected HHs to conduct the coverage survey. \n• Improved process: By streamlini ng this enumeration\, statistical sampling\, and survey process into a sin gle field visit\, GPSSample can substantially reduce time and costs associ ated with conducting coverage surveys\, which has broad benefits to minist ries of health and public health partners. In GPSSample\, teams can collec t foundational public health systems data used in providing services to th e most vulnerable populations such as locations of health facilities and v accination points and missing villages in hard-to-reach places that are of ten overlooked in microplanning efforts for immunization services.\n\nHow does it work?\n\nEnumeration teams can use GPSSample to rapidly enumerate HHs in an EA. Teams can send encrypted data to a supervisor via new local- only mobile hotspot QR code technology developed for GPSSample. The superv isor easily presses a button to generate a simple random sample from eligi ble HHs and sends the list of selected HHs back to the teams. Using GPSSam ple\, teams can navigate back to the selected HHs to conduct surveys. GPSS ample integrates seamlessly with other survey tools like OpenDataKit or XL SForm apps. \n\nGPSSample app has tiered roles facilitating study design and implementation and securely transfers data from GPSSample to ODK and K obo Collect for participants to conduct the longer household survey. \nTie red roles: \n• The Admin sets up the configuration for an area\, study questions\, and defines sampling design \n• The Supervisor defines team s\, manages field work\, selects sample\, reviews data from listing and fr om survey \n• The Enumerator maps and lists households\, collects points of interest\, syncs data with supervisor \n• The Data Collector navigat es back to selected sample\, and completes the longer survey \n\n\nSelecte d Use Cases\n• HH surveys: A district-level HH malaria survey is planne d to estimate malaria prevalence. 14 HHs will be selected in each cluster. High precision is required as the country is approaching elimination. GPS Sample is used to map HHs in clusters and capture structure eligibility fo r the HH survey and an upcoming indoor residual spraying (IRS) campaign in the app. Three teams working in a cluster sync data with their field supe rvisor who draws the sample in GPSSample the same day listing finishes. In GPSSample\, teams use points of interest and HH listing details just coll ected to navigate to HHs selected for the HH survey. A month later\, IRS t eams use IRS eligibility data to ensure all eligible HHs have been visited .\n• Zero dose children: Children missing the first dose of diphtheria\, tetanus\, and pertussis (DTP) containing vaccine (“zero dose”) accoun t for an estimated 50% of vaccine-preventable deaths. Zero dose children a re challenging to identify since they often reside in urban areas\, remote communities\, or conflict-affected areas\, where population estimates are unreliable. By offering the ability to rapidly conduct enumeration and ma pping of targeted areas\, GPSSample provides a valuable solution for ident ifying zero dose children. Through HH listing\, GPS coordinates and contex tual information can be collected\, ensuring precise HH location and incor porating details into digital catchment maps. In conflict zones with restr icted team mobility\, satellite imagery and mapathons are used to identify inhabited structures. Once structures are identified\, teams can safely c onduct HH listing to gather information on zero dose individuals. GPSSampl e streamlines the zero-dose listing process.\n\n\nWorkshop Objectives \nPa rticipants will gain an applied knowledge of the GPSSample application and experience setting up the application for a household cluster field study . \n\nBy the end of the workshop\, participants will gain applied experien ce to:\n• Explain the tiered role of GPSSample application\n• Set up a new configuration and study within GPSSample with a mapping and listing q uestionnaire\, sampling configuration\, and link to an ODK household surve y\n• Create clusters directly in GPSSample by drawing\, specifying a siz e\, or walking the perimeter or bringing in known boundaries \n• Use And roid tablets or phones (OS 8+) to navigate to a cluster\, use GPSSample to map and list households and points of interest\, and to sync data to and from devices\n• Experience the ease of sampling in an offline field envi ronment and navigating back to selected households\n• Decrypt example fi eld data using the GPSSample Decoder App\n\nWhile GPSSample is designed fo r health surveys\, it can be used in other scientific fields too.
