Does revised household-based microplanning improve the performance and reach of polio supplemental immunization activities in Kano State, Nigeria?
Revised household-based microplanning improved the accuracy of demographic estimates and reduced the number of missed children during polio immunization campaigns in Nigeria.
May improve polio SIA targeting in endemic areas; leaves open generalizability beyond observational data in Kano.
BACKGROUND: Remarkable progress had been made since the launch of the Global Polio Eradication Initiative in 1988. However endemic wild poliovirus transmission in Nigeria, Pakistan, and Afghanistan remains an issue of international concern. Poor microplanning has been identified as a major contributor to the high numbers of chronically missed children. METHODS: We assessed the contribution of the revised household-based microplanning process implemented in Kano State from September 2013 to April 2014 to the outcomes of subsequent polio supplemental immunization activities using used preselected planning and outcome indicators. RESULTS: There was a 38% increase in the number of settlements enumerated, a 30% reduction in the number of target households, and a 54% reduction in target children. The reported number of children vaccinated and the doses of oral polio vaccine used during subsequent polio supplemental immunization activities showed a decline. Postvaccination lot quality assurance sampling and chronically missed settlement reports also showed a progressive reduction in the number of children and settlements missed. CONCLUSIONS: We observed improvement in Kano State's performance based on the selected postcampaign performance evaluation indicators and reliability of baseline demographic estimates after the revised household-based microplanning exercise.

Gali et al. (2016) conducted an observational in Polio. Revised household-based microplanning process was evaluated on Planning and outcome indicators of polio supplemental immunization activities. The revised household-based microplanning process led to a 38% increase in enumerated settlements, a 30% reduction in target households, and a 54% reduction in target children.
