Monitoring & Evaluation Reporting


SEDA is an integrated health data and stock-out monitoring system that uses inexpensive and ubiquitous mobile phones for data collection,reporting, and supervision.

Program goals

SEDA analytics allow health system managers to visualize data submitted from health facilities via mobile phone. In collaboration with the ministry, HSI developed 70 specific health indicators that address key health issues in Senegal, including family planning, maternal and child health, malaria, HIV/AIDS referrals, and health commodities/products. These facility-level indicators are reported into a web-based data analytics platform that creates custom data visualizations and dashboards. Supervisors at all levels of the health system can use SEDA to monitor and ensure data consistency and completeness, and analyze data through the system’s predefined dashboards. 

Key program components

SEDA employs user-centered design principles and aligns with existing technologies to provide key indicators. It is possible to scale SEDA nationally wherever GSM networks (the most widely used cell phone technology) are available. Moreover, using ubiquitous and inexpensive technology supports sustainability. SEDA’s open source technology includes Ubuntu Clément Tardif, IntraHealth International In Senegal, the availability and reliability of health data was constrained due to a number of causes. The SEDA mobile phone-based reporting system for health data assists in easier and more timely reporting. IMPLEMENTATION DATE: October 2011 to Present mHEALTH COMPENDIUM VOLUME 5 n 41 server software using a standard GSM gateway, GAMMU SMS texting software, and JSON forms on mobile phone SIM cards to collect structured data. The system protects privacy and security by using phone numbers to authenticate data from the local level. Web-based authentication and security methods protect data at the central server. SEDA aligns with the Ministry of Health’s district-level deployment of DHIS2 by interoperating with DHIS2 as a mobile data collection tool. Aggregate-level data reported into the mobile system from health facilities are automatically uploaded into DHIS2 once validated.
