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.

New Communication About Pain Composite Measure (Updated 3/22/2019)
CMS has released new Pain Management items for the HCAHPS Survey (Questions 12, 13 and 14). The Pain Management items, which focus on communication about pain during the hospital stay, were tested as part of the 2016 HCAHPS mode experiment. A summary of key empirical results from this test, as well as discussion of the “Communication About Pain” measure, can be found here.
Note: The Communication About Pain measure was removed from public reporting in July 2018. The Communication About Pain items will be removed from the HCAHPS Survey beginning with patients discharged in October 2019.
In 2021, CMS conducted a large-scale experiment that will serve a number of purposes. The experiment produced updated adjustments for current HCAHPS measures in the Mail Only, Telephone Only, and Mixed modes of the HCAHPS Survey, which will be applied beginning with patients discharged in January 2023.
The 2021 mode experiment employed a random sample of short-term acute care hospitals that participate in HCAHPS, including hospitals from each of CMS's ten geographic regions. Surveys from patients discharged between April and September 2021 from the 46 participating hospitals were used to develop new adjustments for the HCAHPS Mail Only, Telephone Only, and Mixed survey modes. The adjustments derived from the 2021 mode experiment will more accurately capture the current effect of mode of survey administration on how patients respond.

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).
