Tracker: Expanding DHIS2 into Individual Data
Go beyond aggregate data collection with Tracker, the built-in DHIS2 tool for individual-level data capture, analysis and patient follow up

What is Tracker?
Health programs, school systems, and other large organizations and projects tend to work best when the people managing them can make data-driven decisions. But their ability to analyze data and take informed action on it is limited by the data’s lowest level of disaggregation — the degree of its granularity. Traditionally in a Health Management Information System (HMIS), data are reported in aggregate format — for example, the total number of all cases of a certain disease in a given district for one month —captured on paper forms, and submitted to a central office for manual entry into a database. This kind of data collection was necessary when computers and internet were a rarity, but the time delay in reporting made it difficult to take prompt action to address any issues that the data revealed, and the aggregated nature of the data made it impossible to isolate and follow-up with an individual patient or case. Tracker provides a solution.
DHIS2 decentralizes the data collection process by providing an accessible platform where users can enter data from any level within an organizational system, from the office of the Minister of Health down to a medical worker at an individual health center, using a computer or mobile device to enter data directly into the database in real time. DHIS2 Tracker is a built-in application within DHIS2 that expands the DHIS2 data model from aggregate to individual-level data, turning DHIS2 into a powerful tool for not only collecting and analyzing case-based data (which can be automatically aggregated to meet reporting requirements), but also for managing patient care workflows on a facility or community level. For example, within a Tracker program you can configure SMS reminders, track missed appointments and generate visit schedules for individual patients. Tracker also provides a simple tool for sharing critical clinical health data across multiple health facilities, including by linking Tracker to an Electronic Medical Record (EMR) system.
This page provides an overview of DHIS2 Tracker “in action,” focusing on what Tracker can do and where it is being used, including examples of real-life use cases and information on how you can test the system yourself.

Where is Tracker used?
Tracker is already in use for health and other programs in multiple countries, including national-scale deployments with thousands of users and millions of data records. The following interactive map and chart show countries using Tracker, including additional details for select countries about implementation scope and impact.
What can Tracker do?
Tracker provides a customizable platform for entering, tracking, analyzing, and reporting individual-level data within the DHIS2 software platform. Multiple Tracker programs can be added and maintained in a single DHIS2 instance, and because Tracker comes included as an application within the core DHIS2 platform, no additional software is required. Some key Tracker features include:
- Enroll individuals into longitudinal and chronic programs, and improve retention by using Tracker to schedule visits, set up automated SMS reminders, track missed appointments, and more
- Link individual persons with each other using relationships, and enroll unique records in several health programs without duplicate data entry
- Collect anonymous or one-off (non-longitudinal) individual-level data records using the Event data model
- Define your own case-based programs, decide what data to collect at each stage, and use program rules to simplify data entry forms. OR use DHIS2 WHO data packages for standardized Tracker configurations
- Generate daily or weekly visit schedules (work plans) for your facility or community health workers
- Collect detailed data aligned with standardized codes (such as ICD-10) and surveys (such as WHO’s SARA survey) and link them to aggregate indicators for national and international reporting
- Visualize and analyze your data with tables, charts, graphs, and maps, including the option to easily define custom map areas related to specific programs
- Analyze relationships between tracked entities (such as for contact tracing during a disease outbreak) and visualize relationships on a map
- Collect data online in a web browser, or using Android mobile devices with the DHIS2 Android Capture App in both online and offline modes
