This presentation from an ACS session held on February 10, 2022 focuses on harmonized CNS/NASA resource tracking approaches and experiences in Africa aimed at identifying the elements necessary for successful harmonization and institutionalization of resource tracking. Objectives include understanding the factors facilitating institutionalization, sharing national experiences (Namibia, Botswana) and developing interventions to strengthen harmonization. Harmonization is defined as the merging or synchronization of CNS and NASA approaches to reduce overlap, respondent burden and cost, while maintaining the required level of detail. Success is measured by the production of disaggregated data consistent with classifications, concordance of HIV totals between health accounts and NASA, collection of complete transactions and improved data quality. Practical decisions are discussed: coordination, roles for collection and cleaning, collection tools, data storage, financing, collection methods and validation processes. Institutionalization requires continuity, methodological consistency, national ownership, reliable funding, validity of estimates and usefulness for decision-making. Enabling factors include clear governance, qualified personnel, reporting obligations, automation of data cross-checking, integration with monitoring systems and creation of a data demand. Planned next steps include the tracking survey, sharing of practical documents and finalizing an ACS guide to harmonized resource tracking. Presentations were led by Claire Jones, Teresa Guthrie, André Zida and Allison Kelley, with additional follow-up contacts available.
