Practitioner perspectives on building capacity for evidence-based public health in state health departments in the United States: a qualitative case study

Background Public health agencies are responsible for implementing effective, evidence-based public health programs and policies to reduce the burden of chronic diseases. Evidence-based public health can be facilitated by modifiable administrative evidence-based practices (A-EBPs) (e.g., workforce development, organizational climate), yet little is known about how practitioners view A-EBPs. Thus, the purpose of this qualitative study was to understand state health department practitioners' perceptions about how A-EBPs are implemented and what facilitators and barriers exist to using A-EBPs.Methods Chronic disease prevention and health promotion program staff who were members of the National Association of Chronic Disease Directors were recruited to participate in telephone interviews using a snowball sampling technique. Interviews were transcribed verbatim, and transcripts were analyzed using a common codebook and the a priori method in NVivo.Results Twenty seven interviews were conducted with practitioners in four states (5-8 interviews per state). All practitioners felt that their work unit culture is positive and that leadership encouraged and expected staff to use evidence-based processes. Participants discussed the provision of trainings and technical assistance as key to workforce development and how leaders communicate their expectations. Access to evidence, partnerships, and funding restrictions were the most commonly discussed barriers to the use of A-EBPs and EBDM.Conclusions Results of this study highlight practitioners' perspectives on promoting evidence-based public health in their departments. Findings can inform the development and refinement of resources to improve A-EBP use and organizational and leadership capacity of state health departments.
