What is involved in the survey vendor application process?

When the vendor application period is open, survey vendors need to complete the survey vendor application. Include, in detail, all subcontractor relationships. Be sure to fully document how your organization fulfills the survey vendor minimum business requirements, and submit your application to the survey project team during the application submission period. 

If your organization’s application is approved, you are conditionally-approved as a CAHPS for ACOs Survey vendor. To pursue final approval, key staff – from your organization and your subcontractors – must participate in trainings and pass a quiz incorporated into the training sessions. Only conditionally-approved survey vendors and their subcontractors may participate in training. Details regarding the 2021 Survey Vendor Trainings are posted on the Survey Vendor Training page.

Your organization must also submit a Quality Assurance Plan. Final approval as a CAHPS for ACOs Survey vendor is contingent upon submission of a Quality Assurance Plan and successful participation in training sessions (including a passing quiz score). Approved vendors must also participate in additional training sessions.

My organization has previous experience with web-based survey administration followed by phone follow-up to non-respondents. Does that allow us to meet the mixed-mode experience required to be a CAHPS for ACOs Survey vendor?

No. The mixed-mode experience specified for CAHPS for ACOs Survey administration requires experience with mail survey administration followed by survey administration via Computer Assisted Telephone Interviewing (CATI) with non-respondents. Web-based survey administration experience, combined either with phone (or mail) survey administration, would not meet the mixed-mode requirement.

Are survey vendors allowed to conduct analysis of the CAHPS for ACOs Survey data?

Survey vendors may provide Next Generation ACOs with preliminary survey results. Any data survey vendors wish to append to survey results or sample data for use in analysis must have advance written approval from CMS. All reports survey vendors provide to Next Generation ACOs (whether paper or electronic format) must include a statement that vendor results are unofficial and are for the Next Generation ACO’s internal quality improvement purposes only. Intervention or follow-up with low scoring individuals is not permitted.

Vendors must follow the requirements of an executed CMS Data Use Agreement, and assure that no data that is based on fewer than 11 cases is included in any report of any kind (whether frequency, cross-tabulation, or other data display). Failure to adhere to the CMS Data Use Agreement may constitute a violation of the requirements of the Privacy Act of 1974, the Health Insurance Portability and Accountability Act of 1996 (HIPAA) Privacy Rule and CMS data release policies, and may be considered a breach or violation of data safeguarding. Please visit to learn more about CMS privacy policies and data safeguarding.

What is the data collection protocol for the CAHPS for ACOs Survey?

The CAHPS for ACOs Survey uses a mixed-mode data collection protocol in which mail is the primary mode and Computer Assisted Telephone Interviewing (CATI) is the secondary, non-response, mode. The mail component of the data collection protocol includes mailing of a pre-notification letter, initial survey and cover letter, and a second survey and cover letter to sampled patients who did not respond to the first mailed survey.

Vendors may use a CATI system of their choosing, and the protocol sets a limit of six phone attempts.

Are there any restrictions on fielding other surveys at the same time as CAHPS for ACOs Survey?

This recommendation does not apply to other CMS surveys. Next Generation ACOs should take respondent burden and response rates into account when considering the timing of any additional data collection efforts.
