Evidence-based public health provided through local health departments: Importance of academic-practice partnerships

Objectives. To determine the extent to which US local health departments (LHDs) are engaged in evidence-based public health and whether this is influenced by the presence of an academic health department (AHD) partnership. Methods. We surveyed a cross-sectional stratified random sample of 579 LHDs in 2017.We ascertained the extent of support for evidence-based decision-making and the use of evidence-based interventions in several chronic disease programs and whether the LHD participated in a formal, informal, or no AHD partnership. Results. We received 376 valid responses (response rate 64.9%). There were 192 (51.6%) LHDs with a formal, 80 (21.6%) with an informal, and 99 (26.7%) with no AHD partnership. Participants with formal AHD partnerships reported higher perceived organizational supports for evidence-based decision-making and interventions compared with either informal or no AHD partnerships. The odds of providing 1 or more chronic disease evidence-based intervention were significantly higher in LHDs with formal AHD partnerships compared with LHDs with no AHD partnerships (adjusted odds ratio = 2.3; 95% confidence interval = 1.3, 4.0). Conclusions. Formal academic-practice partnerships can be important means for advancing evidence-based decision-making and for implementing evidencebased programs and policies.
