Overall, about one in eight (12.8%) people younger than 65 with employer coverage switched health plans in 2010down from one in six (17.2%) in 2003, the study found.
As was true in 2003, about 5 percent of people with employer coverage switched plans in 2010 because of a job change. However, the proportion of people changing plans for other reasons fell from 12 percent in 2003 to 7.5 percent in 2010.
Of the 7.5 percent who changed plans in 2010 for reasons other than a job change, most switched plans because of a change in their employer’s benefit offerings (62.7%). The other third of plan changes were worker initiatedusually to obtain a less expensive plan or better quality plan. Among all nonelderly people with employer coverage, 2.3 percent changed plans in 2010 in search of better quality or lower costs.
“These findings suggest that consumer choice plays a relatively small role in health plan switching, with most changes resulting from job changes or changes in employers’ plan offerings,” said study author Peter J. Cunningham, Ph.D., HSC senior fellow and director of quantitative research.
The decrease in plan switching parallels a decrease in employer-sponsored coverage among workers in small and medium-sized businesses who change plans more frequently compared to workers in larger firms, according to the study. The rate of employer coverage among workers in firms with fewer than 500 workers decreased from 63 percent in 2003 to 54 percent in 2010, while employer coverage among workers in larger firms500 workers or moreheld steady at about 83 percent.
The rate at which people change health plans is one indicator of the degree of choice and competition in health insurance markets, which many believe are essential to reduce health care costs and improve quality. For people with employer-sponsored health insurance, opportunities to change health plans are largely constrained by whatever choices employers offer.
Previous research shows about half of workers with employer coverage are offered a single plan by their employer, while only about 15 percent have a choice of three or more plans.
National health reform may create opportunities to increase plan choice among people with employer-sponsored coverage, particularly those in small firms, resulting in more frequent switching, the study noted. However, a potential downside of more switching is less stable patient-provider relationships, such as in a medical home.
Based on the nationally representative HSC 2010 Health Tracking Household Survey, the study examined plan switching among 7,600 nonelderly people with employer coverage. Funded by the Robert Wood Johnson Foundation, the survey included a cell phone sample to account for the growing number of households without a landline phone. Response rates were 45 percent for the landline sample and 29 percent for the cell phone sample.
