Slideshare summarizing key findings of WHO report on the use of Magpi mobile data collection for polio LQAS activities

1. An Essential Tool for Improving Performance in
Polio Endemic Countries
LOT QUALITY ASSURANCE SAMPLING
TO MONITOR SUPPLEMENTAL
IMMUNIZATION ACTIVITY QUALITY

2. Benefits of LQAS
Identifying areas of weak coverage quality
Differentiating areas of varying coverage
Allowing for trend analysis

3. Tailored LQAS for Nigeria:
- clustering
- multiple classification thresholds
Expanded to 7
other countries

4. LQAS AND IM
COMPARISONS

5. 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%

6. 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%

7. INTRODUCTION OF
MOBILE PHONES
FOR DATA
COLLECTION

8. 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.
