Updated HCAHPS Patient-Mix Adjustment (PMA) Document Now Includes Self-Rated Mental Health (04/22/2019)
The HCAHPS PMA model was updated to add Question 28, patient’s self-reported overall mental or emotional health, beginning with July 1, 2018 (Quarter 3, 2018) discharges. The new PMA variable is called Self-Rated Mental Health. In addition, the label for overall health has been changed to “Self-Rated Overall Health.”
Self-Rated Mental Health follows the same linear parameterization as Self-Rated Overall Health: patient responses are coded as 1 (“Excellent”) through 5 (“Poor”). The patient-mix adjustment model will thus include both Self-Rated Overall Health and Self-Rated Mental Health.

CMS to update HCAHPS Survey mode adjustments beginning with patients discharged in January 2025*
In 2021, CMS conducted a large-scale, randomized HCAHPS mode experiment. The experiment allowed calculation of survey mode adjustments applicable to all modes, both the legacy modes (Mail Only, Phone Only, and Mixed Mode) and the new Web-First modes (Web-Mail, Web-Phone, and Web-Mail-Phone).
The new Web-First adjustments will be applied when the new Web-First modes are launched in January 2025. Patients discharged in January 2025 will receive the updated HCAHPS Survey. Patients discharged in January 2025 will receive the updated HCAHPS Survey. Please click here to view the HCAHPS Survey mode adjustment table for patients discharged January 2025 and forward.

*Pending final approval of the proposed HCAHPS Survey changes included in the FY 2025 proposed Hospital Inpatient Prospective Payment Systems for Acute Care Hospitals Rule (CMS-1808-P).
The 2016 Mode Experiment was based on a nationwide random sample of short-term acute care hospitals. Hospitals from each of CMS' ten geographic regions participated in the Mode Experiment. A hospital's probability of being selected for the sample was proportional to its volume of discharges, which guaranteed that each patient would have an equal probability of being sampled for the experiment. The participating hospitals contributed patient discharges from a three-month period: January, February, and March 2016. Within each hospital, an equal number of patients were randomly assigned to each of the four modes of survey administration. A randomized mode experiment of 25,504 discharges from 51 hospitals was used to develop adjustments for the effects of survey mode (Mail Only, Telephone Only, Mixed mode, or Active Interactive Voice Response) on responses to the CAHPS® Hospital Survey (also known as Hospital CAHPS or HCAHPS).
The 2006 Mode Experiment was based on a nationwide random sample of short-term acute care hospitals. Hospitals from each of CMS' ten geographic regions participated in the Mode Experiment. A hospital's probability of being selected for the sample was proportional to its volume of discharges, which guaranteed that each patient would have an equal probability of being sampled for the experiment. The participating hospitals contributed patient discharges from a four-month period: February, March, April, and May 2006. Within each hospital, an equal number of patients were randomly assigned to each of the four modes of survey administration. A randomized mode experiment of 27,229 discharges from 45 hospitals was used to develop adjustments for the effects of survey mode (Mail Only, Telephone Only, Mixed mode, or Active Interactive Voice Response) on responses to the CAHPS® Hospital Survey (also known as Hospital CAHPS or HCAHPS).
