An Essential Tool for Improving Performance in Polio Endemic Countries
LOT QUALITY ASSURANCE SAMPLING TO MONITOR SUPPLEMENTAL
IMMUNIZATION ACTIVITY QUALITY
Benefits of LQAS
Identifying areas of weak coverage quality
Differentiating areas of varying coverage
Allowing for trend analysis
Tailored LQAS for Nigeria: - clustering - multiple classification thresholds
Expanded to 7 other countries
LQAS AND IM COMPARISONS
In Nigeria, IM only captures 5.3% of the LQAS variance
If IM reports coverage >90%, a 48% chance
LQAS will report a covered fraction
<80%
In Pakistan, IM only captures 12% of the LQAS variance
If IM reports coverage >95%, a 29% chance
LQAS will report a covered fraction
<90%
INTRODUCTION OF MOBILE PHONES
FOR DATA COLLECTION
Results observed: - data transmission took place in real-time - no data were lost, the error rate was <1% - transmission cost negligible compared to
the gains in timeliness - data export from server to local
computer was immediate
Data collected on the mobile phones uploaded, exported, and ready for analysis within 2 days, whereas the paper forms require 4–5 days for processing.
