This study presents an uncontrolled preliminary evaluation of a pilot health insurance subsidy program and addresses whether provision of subsidized insurance that required employee contribution had an impact upon preventive health utilization among small businesses and their employees. Self-report questionnaires were mailed to the employees; these included questions on use of preventive health services before and after enrollment in the subsidy program. The analysis was stratified by self-reported prior enrollment in an insurance program to compare employees with and without prior health insurance. The findings suggest significant increases in health service utilization among the previously uninsured. Regular checkups more than doubled (p < .0001), as did the number of individuals receiving regular blood work (p < .0001). Nearly twice the number of individuals filled regular prescriptions after enrollment in the subsidy program as compared with before (p < .0001). This study suggests that employees of small businesses are willing to contribute to the cost of a health insurance premium, and once insured are more likely to use preventive services. A model of shared cost responsibility is an effective way to provide affordable insurance to small-business employees, thus increasing preventive services in these populations.
