Between 26 July-10 August 2012, a pilot of the new GAVI Alliance Immunization Data Quality Assessment tool (IDQA) was conducted in Bolivia. The assessment team included members from the Bolivian MoH, GAVI, the US Centers for Disease Control and Prevention (CDC) and the PAHO. Two previous pilot activities have been performed in 2012 in Ghana and Uganda. The objective of this activity was to field test the IDQA protocol developed in 2011, in collaboration with an ad hoc task team in a Latin American country, in order to assess the capacity of the tool for diverse country-specific settings and inform the use of the IDQA rollout, expected in 2013. Bolivia has had an excellent record in immun-ization data quality, as evidenced by results from a data quality assess-ment performed in 2010, as part of an EPI evaluation conducted by PAHO.

The IDQA pilot testing in 2012 began with data collection and interviews of personnel from the national EPI programme and Health Information System programme. Next, the team visited four municipalities (randomly selected) and 24 health facilities randomly selected within each municipality. The assessment protocol in-cluded staff interviews on data collection, reporting and archiving practices at each administrative level (national, municipality, health unit); collection of vaccination coverage data for pentavalent, OPV, rotavirus and MMR from multiple sources including daily registry books, vaccination cards, and monthly reports; collection of vaccine stock data; direct observation of vaccination and recording practices; and data comparison between sources and levels of data aggrega-tion.

Overall, results demonstrated excellent agreement between the different data sources within each administrative level (e.g. vaccine register vs. monthly report) as well as between data from different administrative level (monthly reports from health unit vs. aggregated data at municipality). This highlighted strong data recording practices, aided by the routine use of a basic data comparison supervision tool at health facilities since the early 2000's. The integration of immunization data into the national Health Information System was also a contributor to maintaining high data quality. The results of the assessment, as well as recommendations for improvement, were presented to the Vice-Minister of health and other Bolivian health authorities at the closure of the activity on 10 August 2012. Finally, the lessons learned from this IDQA pilot and others will be considered by GAVI to finalize the IDQA tool.
