I can’t find any guidance on this specific aspect of supply chain integration, although others may be able to point out something I’ve missed. The following may or may not be of interest to you, but I do know that Project Optimize produced several documents on the wider topic of supply chain integration (not specifically transportation of non-cold chain items in refrigerated vehicles). I list these below in case you are unfamiliar with them.
Integrating the supply chains of vaccines and other health commodities
This evidence brief examines the benefits, challenges, and rationale for integrating vaccine supply chains with the supply chains of other health commodities. It provides agencies, donors, decision-makers, and partners with a brief overview of supply chain integration and lessons learned during project Optimize’s demonstration activities in Senegal and Tunisia.
Integration of vaccine supply chains with other health commodity supply chains: A framework for decision-making
This project Optimize document provides national immunization program managers, their technical support staff, policymakers in ministries of health, and global agencies involved in vaccine and health product supply chains with a better understanding of the benefits and potential risks of integrating vaccine supply chains with other health commodity supply chains. It can also be used as a resource to guide the alignment and coordination of various international initiatives around supply chain integration.
The Senegal Report and Tunisia Report contain more details on the various demonstration projects conducted by Project Optimize relating to integration.
"Between 2009 and 2012, project Optimize worked with the ministries of health in Senegal and Tunisia to document and demonstrate efforts to integrate vaccine products with other health commodities at both national and subnational levels. In Senegal, the immunization program attempted full product integration at the national level. The immunization program transferred the functions of vaccine receiving, storage, and distribution to the national pharmaceutical distribution center (called PNA). Additionally, in the region of Saint Louis, the immunization program transferred responsibility for vaccine storage from the regional vaccine store to the regional medical store. From there, two delivery trucks, called moving warehouses, were employed to transport vaccines and other health products monthly to more than 100 health centers and posts, bypassing district warehouses and saving health personnel time spent collecting vaccines from higher-level stores. The moving warehouses were equipped with computer equipment and software to track stock levels and consumption and with staff to provide technical assistance and supportive supervision while replenishing stock."
