A regular supply of commodities such as contraceptives (including long-acting reversible contraception), HIV test kits, and antiretroviral drugs is essential to the success of service integration. Examining the strengths and weaknesses of the supply chain should reveal where improvements are needed. In order for sustainable HIV and FP service integration to happen on a large scale, the contraceptive needs of HIV platforms must be considered during contraceptive security fora at the national and global levels. The materials available in this section of the Toolkit can help program managers determine how to link with the appropriate supply chains and establish systems to monitor logistics for all commodities.
