The Outpatient and Ambulatory Surgery Patient Experience of Care Survey (OAS CAHPS) will collect information about patients’ experiences of care in hospital outpatient surgery departments (HOPDs) and ambulatory surgery centers (ASCs).


Starting in 2016, CMS plans to launch voluntary monthly data collection using the OAS CAHPS tool. Like HCAHPS, this is a continuous survey. The data will be publicly reported in 2018.

The finalized OAS CAHPS survey contains 37 questions about the check-in process, facility environment, patient’s experience communicating with administrative staff (receptionists) and clinical providers (doctors and nurses), attention to comfort, pain control, provision of pre- and post- surgery care information, overall experience, and patient characteristics.

The survey is designed to meet the following goals:

  • To produce comparable data on the patient’s perspective that allows objective and meaningful comparisons between HOPDs and free-standing ASCs on domains that are important to consumers.

  • Public reporting will allow consumers to make more informed choices when choosing an HOPD or ASC.

  • Public reporting of survey results will be used by HOPDs and ASCs for quality improvement initiatives

    OAS CAHPS Frequently Asked Questions


    Q: What does the OAS CAHPS survey measure?

    A: The finalized OAS CAHPS survey contains 37 questions about the following topics:  Preparation for the surgery/procedure, Check in and pre-operative process, cleanliness and privacy of the facility, surgery facility staff communication, discharge instructions, preparation for the recovery at home, patient reported complications, overall rating of surgery center and willingness to recommend. Three answer options – Yes, definitely / Yes, somewhat / No

    Can add up to 10 additional questions


    Q: When does official data collection begin for the OSCAHPS survey?

    A: Starting in January 2016, CMS plans to launch voluntary monthly data collection using the OAS CAHPS tool. Surveying is continuous from start. Must start at the beginning of a quarter, ie, Q1,Q2,Q3 or Q4  


    Q: Which patients are eligible for the survey?

    A: The OAS CAHPS survey will focus on adult patients who had specific surgeries performed in an outpatient setting(CPT code – 10021-69990 or G-code – G0104, G0105, G0121, G0260). Patients who are admitted as Inpatients will be excluded.  All patients are eligible, not just Medicare/Medicaid patients.


    Q: How many patients will be surveyed?

    A: CMS has indicated that participating facilities must target a minimum of 300 completed surveys per year.


    Q: What are the approved survey modes for OAS CAHPS?

    A: CMS has approved three modes of administration: mail only, telephone only, and mail with a telephone follow-up.


    Q: Does my organization need to use a vendor to complete the 2016 voluntary survey administration?

    A: Yes. In 2016, the OAS CAHPS survey must be administered by an independent CMS-certified vendor. MedStatix is not a certified vendor.


    Q. Any differences between OAS and CG-CAHPS or PQRS. A.OAS is more similar to HCAHPS due to the fact that it is continuous and all patients are eligible. Also, OAS has additional required fields: Discharge Status, Patient Admission Source and CPT codes


    Q: If OAS CAHPS is not yet required, why should we start measuring now?

    A: Our advice would be not to incur the additional costs for a voluntary survey. Our ASC survey can be used to benchmark and predict results for the OAS CAHPS if it does become mandatory.



Becker’s Hospital Review had a recent article on improving the physician-patient relationship. In addition to this list, we would suggest 5 steps we have in our CLEAR initiative. 1. Connect with the patient. 2. Listen to the patient. 3. Explain what you are doing. 4. Agree on a treatment plan with the patient. 5. Have the patient Repeat the treatment plan.

Here’s 5 ways to improve the relationship according to William Maples, MD, executive director and chief experience officer of The Institute for Healthcare Excellenceand CMO of Professional Research Consultants.

1. Understand how patient experience impacts quality, safety and efficiency.

2. Invest in providing physicians and caregivers skills. Learning about communication in a skilled-based learning format, where physicians and caregivers are actually practicing skills they need, can position a healthcare organization for improvement on all levels.

3. Engage physician leadership. Physician leaders are not always part of the conversation on how to improve the patient experience, but it is necessary to invite them to lead this effort.

4. Be patient. There is often a need for immediate gratification when it comes to improving patient experience scores or creating a positive culture change. Healthcare leaders want to see scores go up next month and witness the shift to a patient-centered, team-based culture, but neither of these are brisk tasks.

5. Plan to engage every single person on the caregiver team. This includes employees from the business office and environmental services to nurses and physicians.
