Translating evidence into action: Sharing economic outcomes with employers to impact vaccination policies and practices

Background and Objectives: The Worksite Influenza Vaccination Study (WIVS) was a multisite, prospective study conducted to evaluate the impact of customized, evidence-based interventions on vaccination rates among industrial employees and dependents. Following study completion, findings were presented to corporate decision-makers to encourage expansion of vaccination programs. Methods: Researchers met individually with medical directors, benefits consultants, and wellness program vendors from 18 corporations to share findings, including survey (baseline N=1,000; follow-up N=1,260) and claims data (N=13,520). Participants shared information on their corporations’ vaccination program features and outcomes. Results: All employers offered onsite influenza vaccination for employees. Dependents, part-timers, and contractors were typically not invited to participate. Vaccination rates were variable (20% to 84%% U.S.; 70% Brazil; 95% Mexico) and decreasing over time. Educational programs were the main strategy for increasing vaccination rates, but were not effective. Employers had not established program goals and vendors were not held accountable for outcomes. WIVS data that resonated with participants included economic findings (employees had symptoms (45%), presenteeism (82%), absenteeism (31%), lost wages ($700,000), and healthcare utilization (30%) due to influenza-like illness); the failure of educational programs; and low vaccine uptake among employees with multiple comorbidities and >6 visits to healthcare providers during influenza season (39%). Employers recommended setting goals, inviting families to participate, bringing vaccine to workstations, and developing return-on-investment models. Conclusions: Employers and wellness program vendors have an economic interest in preventing influenza. Program strategies may be impacted by evidence regarding the effect of vaccination on productivity, healthcare costs, and employee engagement.
