In the 1980s and 1990s, the typical country reproductive health program was a vertical program that managed between 6 - 10 contraceptives. Supply chains were relatively easy to establish and maintain as programs generally worked with a single entity. This included, for example, the Family Planning Unit of the Ministry of Health, as well as NGO programs, which often received contraceptives through the same or similar vertical supply chains as the public sector programs. With the current trend toward integration of health programs, however, the logistics situation has become considerably more complex. The list of commodities has increased as has the number of people and units involved. Presently, country health programs are working with supply chains that deal with 600 products or more. In most cases, the increase in the number of types of commodities has been incremental. For example, in Malawi, the DELIVER Project at first supported supply chains that included only family planning products, then STI drugs were added. In Tanzania, family planning products were at first separate, and then were integrated into the essential drug supply chain, which also includes most other public health product groups. (excerpt)
