The 'promote health and prevent disease, disability, and injury' function was initially cast as two functions, with 'promote better health' separate. In examining the mission statements and goals of health promotion and prevention units across the jurisdictions it was clear that there was no hard boundary between the promotion of health and the prevention of disease, disability and injury. In consultations it was suggested that the two functions should be married together as the distinction is increasingly blurry in practice. They have thus been joined as one function at the top level.
