Switching health insurance and its effects on access to physician services.

BACKGROUND: This study examines the factors associated with discontinuous health insurance coverage without periods of uninsurance during the past year (ie, switching coverage), and whether it has a detrimental effect on basic access to care. RESEARCH DESIGN: We analyze the 2003 California Health Interview Survey samples of adults, ages 19-64 (n = 32,850) and children, ages 0-18 (n = 13,062), using weighted bivariate and multivariate analyses. We stratified the population first by age (modeling adults separately from children) and then by health status (modeling the full population and the population reporting fair or poor health separately). RESULTS: Income, race/ethnicity, age, gender, and rural status were significant factors associated with switching coverage. Adults who switched insurance had significantly reduced odds of having a usual source of care [odds ratio (OR) = 0.63, P < 0.001)] compared with those with continuous coverage. In addition, adults and children who switched coverage were significantly more likely to report delaying care because of cost or insurance issues (adults: OR = 1.65, P < 0.001; children: OR = 2.00, P < 0.001). Children in fair or poor health who switched insurance coverage had much higher odds of reporting a delay in care (OR = 5.48, P < 0.001). CONCLUSIONS: Children and adults had disruptions in their basic access to health care when they experienced discontinuous insurance. These findings highlight the advantages of retention of enrollees as one means of promoting access to health care, in the short term, and the benefit of a continuous national health insurance program in the long term.

California American Indian and Alaska natives tribal groups' care access and utilization of care: policy implications.

Background. We used the 2001 California Health Interview Survey (CHIS) to examine differences in cancer care access and utilization by subgroups of American Indian and Alaskan Natives (AIAN). Methods. The CHIS 2001 includes over 55,000 Californian households, with an oversampling of California American Indian, non-California AIAN, and unknown AIAN tribal groups. Results. We found significant differences among the 3 tribal subgroups for various measures of health care coverage and utilization. Conclusions. AIAN must be disaggregated to provide appropriate data for public health and policy making.

American Indians and Alaska Natives in California: women's cancer screening and results.

BACKGROUND AND METHODS: The purpose of this article was to examine differences in demographics, general health status, and utilization of breast and cervical cancer screening for subgroups of American Indians and Alaska Natives (AIAN) using the 2001 California Health Interview Survey. RESULTS: The statewide distribution of California American Indians, non-California AIANs, and unknown AIANs are 10%, 51%, and 39%, respectively. Significant differences exist among the 3 tribal subgroups. CONCLUSIONS: Overall, AIAN women aged 40+ years are close to the Healthy People 2010 goals for receipt of a mammogram in the past 2 years and for receipt of a Pap test ever and in the past 3 years. Less than 5% of AIAN in California report Indian Health Service coverage.
