The document discusses improving Nigeria's national health information system through developing a master facility list (MFL). It outlines how the fragmented previous system lacked integration. The MFL provides a unique identifier for each health facility to standardize data collection across systems. It was developed through a collaborative process but implementing it across electronic platforms remains a challenge. Next steps include fully migrating the MFL online and ensuring it can interface with other health information systems. The MFL is important for sampling, service distribution analysis, and linking facilities across systems to improve evidence-based decision making.
