Purpose:
To evaluate an evidence-based workplace approach to increasing adult influenza vaccination levels applied in the restaurant setting
Design:
We implemented an intervention and conducted a pre/post analysis to determine effect on vaccination.
Setting:
Eleven Seattle-area restaurants.
Subjects:
Restaurants with 25+ employees speaking English or Spanish and over 18 years.
Intervention:
Restaurants received influenza vaccination promotion materials, assistance arranging on-site vaccination events, and free influenza vaccinations for employees.
Measures:
Pre/post employee surveys of vaccination status with direct observation and employer interviews to evaluate implementation.
Analysis:
We conducted descriptive analysis of employee survey data and performed qualitative analysis of implementation data. To assess intervention effect, we used a mixed-effects logistic regression model with a restaurant-specific random effect.
Results:
Vaccination levels increased from 26% to 46% (adjusted odds ratio 2.33, 95% confidence interval 1.69, 3.22), with 428 employees surveyed preintervention, 305 surveyed postintervention, and response rates of 73% and 55%, respectively. The intervention was effective across subgroups, but there were restaurant-level differences.
Conclusion:
An access-based workplace intervention can increase influenza vaccination levels in restaurant employees, but restaurant-level factors may influence success.
