This document drew from publications, the recommendations of more than 100 experts in Family Planning (FP) and HIV/AIDS, and lessons learned from field experience. The document is designed to help people make appropriate decisions about whether to pursue the integration of FP and HIV services. It also explains how to pursue integration in a strategic and systematic manner, in order to achieve maximum public health benefit. The document places four questions at the center of FP/HIV integration policy: What type of service integration, if any, is needed? To what extent should services be integrated? What steps are needed to establish and sustain high-quality integrated services? What information is needed to measure program success and inform program/service delivery improvement, replication, and/or scale-up? The document guides readers through the process of finding answers to these questions that are appropriate to their countries' circumstances. Where integration appears to be the right course of action, the document helps readers identify action steps to establish or enhance integrated FP/HIV services. It also provides links to resources that will support the implementation of those action steps, such as facility assessment tools, training curricula, and job aids.
