INTRAHEALTH INTERNATIONAL: STRENGTHENING HEALTH SYSTEMS & IMPROVING SERVICES IN TANZANIA USING DATA

Transforming tabular data into visualizations

Background

In Tanzania, IntraHealth International is involved in HIV prevention, family planning, and reproductive health services. IntraHealth leans on the use of technology and data for stronger decision-making and to help officials plan for, recruit, and deploy an effective health workforce.

Since 2011 IntraHealth has been working in five regions in Tanzania in sectors related to Gender Based Violence (GBV), HIV Testing and Counselling (HTC), and Voluntary Medical Male Circumcision (VMMC) programs. Effective planning for the implementation of these projects requires knowing who the service recipients are and where they are located.

 

Problem

IntraHealth has been tracking their patient populations using tabular data, but this system provides only a limited perspective on patient services. Transforming that tabular data into data with a geospatial component is a need they have to better understand the distribution of patients in a region relative to the location of the nearest IntraHealth facility, find the  percentage of a local population that is being served by IntraHealth, and where unserved or underserved populations are in need of additional health resources.

 

Solution

Develop a clear and dynamic understanding of where IntraHealth’s clinics are located within districts relative to the population distribution will enable IntraHealth to identify the population base that is being served by the existing facilities. Paired with district-level population data, IntraHealth will understand what fraction of the population the organization is serving in the districts where they operate. The dLab will help IntraHealth create geovisualizations and train staff so they can do these on their own. These visualizations will help IntraHealth identify opportunities for growth, select facilities best suited to providing additional services, and determine where to focus outreach and engagement activities such as conducting public (street) awareness campaigns.

 

PROCESSES

One of the most powerful ways to add value to an existing data set is to integrate data from other sources. While IntraHealth’s own data could tell them how their facilities were performing relative to each other, joining that data with population and geospatial data from the National Bureau of Statistics (NBS) and geotagged health facilities from the Health Facility Registry give IntraHealth a much more complete picture.

 

 

For example… 2-3 sentences about viz/ vizzes that are included. Relate this back to the solution section. Include tabular dat versus data vis

 

Joining data from disparate sources can be challenging. For example, discrepancies in naming systems between IntraHealth’s records and the Health Facility Registry required manual matching of each facility to its geographic coordinates. The time-consuming process – impractical at larger scales – underscores the need for data compatibility across sectors and among different stakeholders through the use of standardized naming systems or alphanumeric codes.

 

No data use project would be complete without a critical analysis on how future data collection strategies could be tailored to create a more robust product in the next iteration. In this case, it was noted that IntraHealth collects age data on their patients in aggregated age bands, and the composition of those age bands has changed over time. This strategy precludes a direct comparison between services offered to certain population subsets from year to year. As a best practice going forward, dLab is proposing that IntraHealth keep the datasets in two presentation formats, one for donor reporting which will be produced based on donor specifications, including any age aggregation, and another, more disaggregated data set to be shared with other stakeholders and used internally.

 

OUTCOMES & IMPACTS

As a result of the data analysis and visualization undertaken in collaboration with the dLab, IntraHealth International will be in a position to

  • Understand the number of beneficiaries of IntraHealth’s services as compared to the total local population and to the target number of beneficiaries, thereby allowing IntraHealth to quantitatively assess the performance of each facility;
  • Locate populations that are unserved or underserved by IntraHealth’s facilities and allocate resources to making IntraHealth’s services more available, e.g. through increased staffing, extended facility hours, or services at new locations;
  • Plan for targeted outreach sensitization campaigns in areas where IntraHealth’s services are reaching a relatively lower percentage of the population;
  • Identify the highest-performing facilities and use that identification as a starting point for improving services in lower-performing facilities.

The dLab Data Science team has additionally identified an area where improved data collection on the part of IntraHealth could lead to more informative analyses in future work.
