Objective: To present preliminary efforts to establish an internationally agreed set of minimum core practice and best practice guidelines, along with overarching principles to promote safe and comprehensive cleft care globally. Design: Representatives from 6 national and international organizations collaborated to form a World Cleft Coalition. Representatives met monthly/bimonthly to compile standards for safe, comprehensive, and sustainable cleft care. Outcomes were circulated within each organization and to a small subset of external constituents for feedback. Results: A series of overarching principles were established for those involved in International Cleft Treatment Programs, based on the experience of participating organizations. The overarching principles are followed by a structured and detailed Recommended Practice for Ensuring Safe, Comprehensive and Sustainable Cleft Care, which includes minimum core and best practice for the following areas: surgical safety, quality control, patient education, patient selection, patient follow-up, comprehensive care, partnership with the host nations and professionals, training and exchanges for sustainability, and local capacity building. Conclusions: Outcomes aimed to provide a working document to define core principles for safe comprehensive cleft care, while balancing various levels of resources, geographic locations, appropriately trained health care professional specialists, and training limitations. The study highlights the process and benefits to a collaborative international working group not only to establish best practice but also to solicit and engage others in discussion of their experiences with building and supporting safe, high-quality, comprehensive, sustainable, worldwide cleft care.
