Objectives: Evidence-based decision making (EBDM) allows public health practitioners to implement effective programs and policies fitting the preferences of their communities. To engage in EBDM, practitioners must have skills themselves, their agencies must engage in administrative evidence-based practices (A-EBPs), and leaders must encourage the use of EBDM. We conducted this longitudinal study to quantify perceptions of individual EBDM skills and A-EBPs, as well as the longitudinal associations between the 2.
Methods: An online survey completed among US state health department practitioners in 2016 and 2018 assessed perceptions of respondents' skills in EBDM and A-EBPs. We used χ2 tests, t tests, and linear regressions to quantify changes over time, differences by demographic characteristics, and longitudinal associations between individual skills and A-EBPs among respondents who completed both surveys (N = 336).
Results: Means of most individual EBDM skills and A-EBPs did not change significantly from 2016 to 2018. We found significant positive associations between changes in A-EBPs and changes in EBDM skill gaps: for example, a 1-point increase in the relationships and partnerships score was associated with a narrowing of the EBDM skill gap (β estimate = 0.38; 95% CI, 0.15-0.61). At both time points, perceived skills and A-EBPs related to financial practices were low.
Conclusions: Findings from this study can guide the development and dissemination of initiatives designed to simultaneously improve individual and organizational capacity for EBDM in public health settings. Future studies should focus on types of strategies most effective to build capacity in particular types of agencies and practitioners, to ultimately improve public health practice.
