The Association Between Evidence-Based Decision Making and Accreditation of State Health Departments

To assess the association between evidence-based decision making, including implementation of evidence-based interventions (EBIs), with accreditation of state health departments through the Public Health Accreditation Board (PHAB).

This was a cross-sectional, electronic survey of state health department practitioners. We utilized a survey instrument focused on evidence-based public health, de-implementation, and sustainability of public health programs. Survey questions were organized into 6 domains: (1) demographic information; (2) individual-level skills; (3) decision making on programs ending; (4) decision making on programs continuing; (5) organization/agency capacity; and (6) external influences.

The targeted practitioners were randomly selected from the 3000-person membership of National Association of Chronic Disease Directors and program manager lists from key Centers for Disease Control and Prevention-supported programs in cancer and cancer risk factors. The final target audience for the survey totaled 1329 practitioners, representing all 50 states.

The main outcome measures included the strength of association between a state's PHAB accreditation status and variables related to evidence-based public health and use of EBIs that fell within the individual participant skills, organization/agency capacity, and external influences domains.

We received 643 valid responses (response rate = 48.4%), representing all 50 states, with 35 states being PHAB accredited. There was a statistically significant association between PHAB accreditation and state health department use of quality improvement processes (P = .002), leadership plans to implement EBIs (P = .009), and leadership reactions to EBI implementation issues (P = .004). Respondents from PHAB-accredited states were significantly more likely than participants from nonaccredited states to report greater engagement with legislators and governors regarding EBIs and 14% less likely to report the inappropriate termination of programs in their work unit (P = .05).

The importance of accreditation relates to both internally focused functions and externally focused activities, especially regarding policy-related impact.
