Background Recommendations by the Lancet Commission on Global Surgery regarding surgical care in low-and middle-income countries (LMICs) require development to address the needs of children. The Global Initiative for Children's Surgery (GICS) was founded in 2016 to identify solutions to problems in children's surgery by utilizing the expertise of practitioners from around the world. This report details this unique process and underlying principles. Methods Three global meetings convened providers of surgical services for children. Through working group meetings, participants reviewed the status of global children's surgery to develop priorities and identify necessary resources for implementation. Working groups were formed under LMIC leadership to address specific priorities. By creating networking opportunities, GICS has promoted the development of LMIC-LMIC and HIC-LMIC partnerships. Results GICS members identified priorities for children's surgical care within four pillars: infrastructure, service delivery, training and research. Guidelines for provision of care at every healthcare level based on these pillars were created. Seventeen subspecialty, LMIC chaired working groups developed the Optimal Resources for Children's Surgery (OReCS) document. The guidelines are stratified by subspecialty and level of health care: primary health center, first-, second-and third-level hospitals, and the national children's hospital. The OReCS document delineates the personnel, equipment, facilities, procedures, training, research and quality improvement components at all levels of care. Conclusion Worldwide collaboration with leadership by providers from LMICs holds the promise of improving children's surgical care. GICS will continue to evolve in order to achieve the vision of safe, affordable, timely surgical care for all children. Defining the need Surgical burden of disease Since the conclusion of the United Nations' Millennium Development Goals (MDGs) and through the ongoing work toward Sustainable Development Goals (SDGs), tremendous progress has been made toward reducing childhood mortality [1, 2]. However, the care of children with surgical diseases remains an underappreciated and underfunded area in health care, despite congenital Collaborating members are listed in the Acknowledgments.
