Supplemental Process and Documentation Guidance for Tribal Public Health Department Accreditation: In partnership with the National Indian Health Board (NIHB), PHAB has released a new supplemental guide for Tribal health departments to use as they prepare for accreditation. This document is the product of more than a year of work by the NIHB Tribal Public Health Accreditation Advisory Board (TPHAAB), as they reviewed each Standard and Measure for its sensitivity to Tribal public health. The draft document was reviewed by the PHAB Board of Directors and also posted online for public comment. PHAB believes that, if Tribal health departments will use this supplement as a companion document to Version 1.5 of the Standards and Measures, they will find very useful Tribal-centric examples and suggestions for ensuring conformity with the Standards and Measures. PHAB will add to this document as more Tribal-specific examples are obtained. PHAB appreciates the hard work that the TPHAAB put into making this document a reality, and we hope that it will help Tribal health departments be successful in achieving accreditation.
