title: Will uninsured people volunteer for voluntary health insurance? Experience from Washington State.
abstract: OBJECTIVE
  In national and local discussions of health care reform, there is disagreement about whether a national health insurance plan should be mandatory or voluntary. This study describes characteristics of low- income people who were more likely or less likely to be covered by a voluntary plan.
  
  
  METHODS
  Survey data were available from an evaluation of Washington State's Basic Health Plan, which offered subsidized health insurance to low-income residents. For those subjects who were eligible and uninsured at baseline, those who joined were compared with those who did not join on a variety of demographic and health-related characteristics.
  
  
  RESULTS
  There were substantial differences between those who did and did not join the Basic Health Plan. Those who did not enroll were generally less well-off, with less education, lower income, and worse health. Many had never had health insurance.
  
  
  CONCLUSIONS
  If health care reform results in a voluntary plan, additional measures may be needed to ensure that less advantaged citizens have adequate access to health care.
