The ICH CAHPS Survey results that are currently posted on Dialysis Facility Compare (DFC) on the website are based on ICH CAHPS Survey data from the 2018 ICH CAHPS Spring and Fall Surveys. The results shown are statistically adjusted for both data collection mode and for patient-mix. Information about the adjustments made to the survey results and the coefficients used to adjust the results can be found here. Information presented in this document will allow ICH facilities to approximate the effect of patient-mix adjustment on their ICH CAHPS Survey results that were posted on DFC in October 2019. In addition, this document includes additional information on the clustering method used to create ICH CAHPS Star Ratings (Appendix A).
