Leveraging a DHIS2 Based Ecosystem to Improve Health Data Management and Reporting: Innovations from the Monitoring, Reporting, and Evaluation (MORE-ZM) System in Zambia
Supported by the CDC, Zambia's MORE-ZM system transformed fragmented health data management by implementing a centralized DHIS2 ecosystem with automated reporting tools and real-time visualization, significantly reducing reporting times and enhancing data use across 1,584 facilities.

Imagine Zambia's health system before 2020 as a massive, chaotic library where every librarian (or health program) had their own different rulebook, their own filing cabinet, and their own way of writing reports. Some used paper, some used Excel spreadsheets, and everyone was trying to send a summary to the main office (the CDC and PEPFAR) by hand. It was slow, messy, and prone to typos. Getting a single report ready took "several days" of frantic copying and pasting.
Enter the MORE-ZM system, a digital superhero built on a platform called DHIS2. Think of DHIS2 as a giant, open-source Lego set that allows different health programs to build their own unique structures, but with a twist: they all have to use the exact same instruction manual for the bricks.
The Big Idea: One Language, Many Rooms
The paper describes how the team built a "multi-instance" ecosystem. Imagine a huge mansion with 1,584 rooms (representing health facilities across five provinces). Each room has its own door and its own set of keys (a separate DHIS2 instance), so if one room has a power outage, the rest of the mansion keeps running. However, the blueprints for all those rooms come from a single, central architect (central metadata harmonization). This ensures that when someone in the Eastern province counts "HIV tests," they are counting the exact same thing as someone in the Western province.
The Magic Tools: Robots and Dashboards
The team didn't just build the rooms; they installed three clever robots to do the boring work:
The MER Parser (The Translator Robot): Before, staff had to manually take data from Electronic Health Records (EHRs) and type it into a new system. The MER parser is a Python-based robot that grabs those messy files, checks them for errors, and instantly translates them into a clean format the main system can swallow.
- The Result: A task that used to take "several days" of human labor now takes "a few minutes."
The BOB Automation Tool (The Report Generator): Every month, health workers had to fill out a giant Excel template called the "BOB report" to tell donors how they were doing. This was a manual nightmare. The new tool is a robot that dives into the database, grabs the numbers for HIV testing, treatment, and tuberculosis, and automatically fills in the Excel sheet perfectly.
- The Result: These monthly reports, which used to take days, are now generated "within half an hour."
The Power BI Connectors (The Crystal Ball): Instead of waiting for paper reports or static spreadsheets, the team built a bridge between the health data and a visualization tool called Power BI. This acts like a live dashboard or a "crystal ball" that shows trends in real-time.
- The Result: Managers can now see "near real-time" trends in HIV and TB, replacing the old method of waiting for manual CSV exports and pivot tables.
What the Paper Says (and Doesn't Say)
The authors are careful to note that while the system suggests a massive improvement in speed and data quality, they didn't run a formal scientific experiment to measure every single error rate before and after. They observed that the new system reduced manual handling and that cross-checks showed the numbers matched up well, with only tiny timing differences. They explicitly state that the system relies on periodic data exports rather than a live, real-time wiretap of every patient record, so there is still a small delay.
They also point out that this isn't a "magic cure-all" that works everywhere instantly. It required a massive training effort—1,575 staff members were taught how to use the new tools—and it relied on strong teamwork between different health offices and the CDC. The system is described as "suggesting" that automation can transform reporting, rather than claiming it has permanently solved every data problem in the world.
The Bottom Line
The MORE-ZM system shows that by using open-source software (DHIS2) and adding a layer of automation (the robots), you can turn a slow, fragmented reporting process into a fast, streamlined flow of information. It turned a "several days" wait into "minutes" for some tasks and "half an hour" for others. While the paper doesn't claim this is a perfect, finished product, it suggests that this approach offers a scalable blueprint for other places struggling with messy health data, proving that when you give health workers better tools and a common language, they can make decisions faster and more accurately.
