Information on CAHPS Response Patterns
CMS conducts annual analyses to determine non-response patterns for Medicare CAHPS surveys. Unit response rates follow patterns typical for health surveys (Klein et al., 2011), including higher response rates for non-Hispanic whites than for other racial/ethnic subgroups, higher response rates through age 79, and lower response rates for low-income beneficiaries.
Though we do not have specific non-response information for SEER-CAHPS, we recommend referring to and citing relevant analyses using Medicare CAHPS, and using provided weights for SEER-CAHPS analyses to account for sample design and nonresponse. Please find additional information on the CMS website.
