  3. What results are shown in the Preview Reports?
    For each CCN, the Preview Report shows the results for each variable and measure shown below:
    1. The number of patients who were sampled; the number of completed surveys; and the response rate percentage during the reporting period;
    2. The percentage of patients who rated the overall care they received at the HOPD or ASC a "9" or "10" on a scale of 0 (worst care possible) to 10 (best care possible);
    3. The percentage of patients who reported YES, they would definitely recommend the HOPD or ASC to friends and family;

    5. The percentage of patients who reported that the HOPD or ASC staff definitely communicated with them about what to expect during and after the procedure; and
    6. The percentage of patients who reported that the HOPD or ASC staff definitely gave them information about what to do if they had pain, nausea or vomiting, bleeding, or possible signs of infection as a result of the procedure or the anesthesia, if any of these outcomes were experienced.

  4. Which sample months are included in the Preview Report results?

The future anticipated public reporting periods are provided in Table 14.2 of the OAS CAHPS Survey Protocols and Guidelines Manual.
  5. My facility participated in the OAS CAHPS Survey, but there are no results shown. Why?
    OAS CAHPS Survey results are publicly reported when an HOPD or ASC has 4 quarters of OAS CAHPS Survey data. An HOPD or ASC must have had survey response data (patients who responded to the survey) in all 4 quarters included in the public reporting period for results to be publicly reported.
