This measure comes from the annual Adult Consumer Assessment of Healthcare Providers & Systems (CAHPS) survey, which is a questionnaire developed jointly by the Agency for Healthcare Research and Quality (AHRQ) and the National Committee for Quality Assurance.
The survey draws as potential respondents the adult members of Vermont Medicaid who were continuously enrolled in the plan for at least 6 months, with no more than one enrollment gap of 45 days or less. From this sample frame, a random sample of 1,650 cases is drawn.
The red dotted line in the graph above represents the national average of "top box" scores for all State Medicaid plans that submitted their results to the CAHPS database. Approximately 2/3 of states submit their annual CAHPS survey results to the national database. It is entered onto the graph as a comparison to Vermont’s top box scores (e.g. usually or always responses).
