The Colorado Health Access Survey (CHAS) is the most extensive survey in Colorado of health care coverage, access and utilization. A first follow-up to the 2008-2009 Colorado Household Survey, CHAS is administered every other year via a random sample telephone survey of more than 10,000 households across the state – providing detailed information that is representative of the 5 million-plus Coloradans.
A program of The Colorado Trust, CHAS provides information to help policymakers, and health care, business and community leaders more fully understand health challenges and advance shared solutions to improve health coverage and care for Coloradans. The Colorado Health Institute (CHI) managed the data collection and analysis of CHAS.
Unique Attributes of CHAS
- CHAS is the only survey that focuses solely on the health insurance status, access to health care and utilization of health care services of Coloradans.
- Each respondent was asked to give answers for all individuals living in the household, providing a comprehensive understanding of health care issues.
- Interviewers were able to delve deeply into detailed aspects of each component of the survey by asking tailored follow-up questions about each member of the household.
- The customized question set is specific to our state, addressing Colorado programs such as Child Health Plan Plus (CHP+).
- The proportion of chronically uninsured Coloradans can be determined through CHAS findings since survey respondents address the insurance status of household members at the time of the survey, and for the 12 months prior to the survey.
