Dear Mr Jay Rajgopal, Hope I am not very late in responding to your query. based on my practical experience the RED or REC strategy provides a comprehensive guideline for routine immunization outreach planning.
According to this strategy initially a training workshop is organized for the immunization staff in which they present the administrative routine immunization data of their area and bsed on the analysis of this admin data a detailed outreached plan is prepared focussing on the areas where there are maximum number of missed children. A categoraization is made in the form of
Category 1 Good access and Good utilization
Category 2 Good access and poor utilization
Category 3 poor access and Good utilization
Category 4 poor access and poor utilization
After this analysis prioritization is done where category 4 becomes priority 1, the whole area is divided into blocks and each block is assigned to a vaccinator. The analysis also includes the calculation of supplies required, preparation of monitoring plan and other relevant information, in such a way a detiled outreach plan is prepared for the whole year. The complete details of this can be found in RED guide on WHO website. The program has already been successfully implemented in many countries and your country might be one of them.
Hope I have answered most of your queries. I am available if you still need any further support.
