50. The Millennium Declaration committed countries to reducing by two-thirds the mortality rate among children under the age of five. Various organizations of the system have launched important initiatives in this field, working with non-UN partners. These initiatives encompass child immunization, improving child health in the home, child survival and healthy newborns. Over the years, UN organizations have scored major successes in immunizing children and reducing child mortality. An inter-agency working group involving UNICEF, WHO and the World Bank focuses on household and community IMCI (Integrated Management of Childhood Illness). Another multi-agency initiative, the Child Survival Partnership (CSP), formed in 2004, aims at providing a forum for coordinated action to address the main conditions that affect children's health. CSP enables governments and partners to agree on consistent approaches and stimulates concerted efforts towards their implementation. The Healthy Newborn Partnership, an inter-agency group formed in 2000, promotes attention and action to improve newborn health and survival. It also provides a forum for information exchanges on programmatic, research, training and communication issues. The Partnership collaborates actively with other groups working on related objectives, such as the Inter-Agency Group for Safe Motherhood.
