Clinician & Group Database

The CAHPS Clinician & Group Survey (CG-CAHPS) Database is the newest component of the CAHPS Database. It was developed in response to the growing demand for comparative results for the various versions of the CG-CAHPS Survey, including the 6-month and 12-month versions.

Table 2 summarizes the current composition of the CG-CAHPS Database Online Reporting System from data submissions for 2015 to 2016.
