Implication

Randomized trial measures immunization data accuracy in low-income countries, highlighting system weaknesses.

Key Points

  • The aim is to assess the accuracy and quality of immunization information systems in low-income countries receiving GAVI support.
  • Data Quality Audit (DQA) using WHO validated methodology.
  • Comparison of health unit records to national immunization reports.
  • Evaluation of quality indicators at national, district, and health unit levels.
  • Nearly 50% of countries had a verification factor below 80%.
  • Only nine countries demonstrated consistently high verification factor and quality score results.
  • Improvement was noted in all six countries that repeated the DQA, though not statistically significant.
