TI  - Lot quality assurance sampling to monitor supplemental immunization activity 
      quality: an essential tool for improving performance in polio endemic countries.

AB  - Monitoring the quality of supplementary immunization activities (SIAs) is a key 
      tool for polio eradication. Regular monitoring data, however, are often 
      unreliable, showing high coverage levels in virtually all areas, including those 
      with ongoing virus circulation. To address this challenge, lot quality assurance 
      sampling (LQAS) was introduced in 2009 as an additional tool to monitor SIA 
      quality. Now used in 8 countries, LQAS provides a number of programmatic 
      benefits: identifying areas of weak coverage quality with statistical 
      reliability, differentiating areas of varying coverage with greater precision, 
      and allowing for trend analysis of campaign quality. LQAS also accommodates 
      changes to survey format, interpretation thresholds, evaluations of sample size, 
      and data collection through mobile phones to improve timeliness of reporting and 
      allow for visualization of campaign quality. LQAS becomes increasingly important 
      to address remaining gaps in SIA quality and help focus resources on high-risk 
      areas to prevent the continued transmission of wild poliovirus.
