The cultural and linguistic diversity of the U.S. population presents challenges to the design and implementation of population-based surveys that serve to inform public policies. Information derived from such surveys may be less than representative if groups with limited or no English language skills are not included. The California Health Interview Survey (CHIS), first administered in 2001, is a population-based health survey of more than 55,000 California households. This article describes the process that the designers of CHIS 2001 underwent in culturally adapting the survey and translating it into an unprecedented number of languages: Spanish, Chinese, Vietnamese, Korean, and Khmer. The multiethnic and multilingual CHIS 2001 illustrates the importance of cultural and linguistic adaptation in raising the quality of population-based surveys, especially when the populations they intend to represent are as diverse as California's.
Underinsurance is most commonly defined as the state in which people with medical coverage are still exposed to financial risk. We argue that the adequacy of health insurance coverage should also be assessed in terms of the adequacy of specific benefits coverage and access to care. Underinsurance can be understood conceptually as comprising three separate domains: (a) the economic features of health insurance, (b) the benefits covered, and (c) access to health services. The literature provides ample evidence that people who are underinsured have high financial risk and face barriers in access to care similar to those who are completely uninsured. In response to the growing recognition of the problems associated with underinsurance, the Patient Protection and Affordable Care Act of 2010 includes numerous provisions designed to limit costs to consumers, to assure a minimum set of benefits, and to enhance access to care, especially primary care.
This article examines the impact of public and private health insurance on the use of medications for California adults with any of four chronic diseases: heart disease, high blood pressure, diabetes, and asthma. The data set used is the 2001 California Health Interview Survey. Multivariate analyses were conducted on individuals who had been diagnosed with each of these diseases. Controlling for various demographic, health status, and employment characteristics, the authors find that the uninsured are far less likely to be taking medications for each of the conditions than those with private insurance. Interestingly, those with Medicaid coverage are even more likely than those with private insurance to be taking such medications. The results of this study underscore the importance of health insurance for all persons with chronic conditions and the benefits of Medicaid in particular for low-income adults with chronic conditions.
These findings highlight the benefits gained through continuous health insurance, whether public or private. Public policies should be adopted to ensure continuity of coverage and retention in public insurance programs.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
