Mode Experiment | Updated Mode & Patient-Mix Adjustment Abstract | Patient-mix Coefficients for March 2010 Publicly Reported HCAHPS Results have been Posted

Mode Experiment

The 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 was 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).
