NACDD’s “Health Systems Change for Tobacco Cessation Competencies” outlines the essential knowledge and skills required for public health professionals to successfully integrate tobacco cessation into routine clinical care. It establishes five core competency areas, such as building partnerships and embedding cessation protocols into workflows, alongside a five-level proficiency scale for staff self-assessment. This framework provides a roadmap for implementing lasting, system-level transformations that treat tobacco use treatment as a standard component of healthcare.
