Disseminating Evidence-Based Interventions in Small, Low-Wage Worksites: A Randomized Controlled Trial in King County, Washington (2014-2017).

Objectives. To determine whether (1) participating in HealthLinks, and (2) adding wellness committees to HealthLinks increases worksites' evidence-based intervention (EBI) implementation.Methods. We developed HealthLinks to disseminate EBIs to small, low-wage worksites. From 2014 to 2017, we conducted a site-randomized trial in King County, Washington, with 68 small worksites (20-200 employees). We assigned worksites to 1 of 3 arms: HealthLinks, HealthLinks plus wellness committee (HealthLinks+), or delayed control. At baseline, 15 months, and 24 months, we assessed worksites' EBI implementation on a 0% to 100% scale and employees' perceived support for their health behaviors.Results. Postintervention EBI scores in both intervention arms (HealthLinks and HealthLinks+) were significantly higher than in the control arm at 15 months (51%, 51%, and 23%, respectively) and at 24 months (33%, 37%, and 24%, respectively; P < .001). Employees in the intervention arms perceived greater support for their health at 15 and 24 months than did employees in control worksites.Conclusions. HealthLinks is an effective strategy for disseminating EBIs to small worksites in low-wage industries.Public Health Implications. Future research should focus on scaling up HealthLinks, improving EBI maintenance, and measuring impact of these on health behavior.

Tobacco Evidence-Based Practice Implementation and Employee Tobacco-Related Outcomes at Small Low-Wage Worksites.

OBJECTIVE: The aim of this study was to assess whether tobacco policy, program, and communication evidence-based practice implementation is associated with employee tobacco outcomes [current smoking; quit attempt; smokeless tobacco (SLT) use; and perceived worksite support for cessation] at small low-wage worksites. METHODS: We analyzed data from a randomized controlled trial testing an intervention to increase implementation of evidence-based health promotion practices. We used generalized estimating equations to examine relationships between practice implementation and tobacco outcomes. RESULTS: Communication practice implementation was associated with better perceived worksite support for cessation (P = 0.027). Policy and program implementation were associated with increased odds of being a current SLT user; these findings should be interpreted with caution given small sample sizes. CONCLUSION: Tobacco communication evidence-based practice implementation was associated with favorable perceptions of worksite support for cessation; more may be needed to change tobacco use behavior.
