In 2007, the Division of Reproductive Health (DRH) at the U.S. Centers for Disease Control and Prevention (CDC) developed the Reproductive Health Assessment Toolkit for Conflict-Affected Women (RHA Toolkit), to assess the reproductive health needs of crisis-affected women. Funding for the development of the RHA Toolkit was provided by the U.S. Agency for International Development (USAID) and the Andrew Mellon Foundation. In anticipation of the final year of the funding cycle (2010–11), DRH undertook a process evaluation in 2009 to examine if the toolkit provides necessary and useful tools to guide program staff in collecting reproductive health data that inform program planning in crisis settings. In this report we present the results of that evaluation, including an examination of the factors that affect the use of the RHA Toolkit, and provide recommendations to sustain the RHA Toolkit post funding. This report includes ten sections. The first section of this report provides an overview of the reproductive health in crisis field, outlining key actors and initiatives as well as the role of the RHA Toolkit in enhancing comprehensive reproductive health programming. The second and third sections outline the aim of this report and describe the methods used to perform the process evaluation. The fourth and fifth sections outline the findings of this evaluation, as well as cross-cutting themes related to data collection, analysis, and dissemination. The final sections outline lessons learned and recommendations and introduces initiatives undertaken to sustain the RHA Toolkit post funding.
