The patient surveys are Medicare requirements for ACOs participating in Medicare initiatives, as well as CAHPS under MIPS
Not sure how it pertains to pre-clinical students (unless your school have you start clinical rotations while a 2nd year student) ... but right now patient experience surveys are what hospital administrators, CMS and HHS administrators want, as part of the overall assessment (and determining reimbursement or penalties)
As for medical students (pre-clinical or even clinical) - I don't see how the school can use the results for grades. There's usually a delay in response (it takes weeks, and most patients aren't computer savy enough to fill out online surveys so will need paper survey that mails in, and mail back). A lot of time negative experiences are out of students (and even clinician hands) - upset that patient was kept NPO due to SBO, or low salt CHF diet wasn't up to their standards. And the sample size isn't even close to being representative.
And as a resident/fellow, you will get sick of the term "360 evaluation" where you are evaluated by nurses, janitors, patients, families, attendings, residents, students, hospital operator, hospital security, etc that ACGME mandates
But unfortunately it is the future (until someone reasonable in hospital admin and government realize the flaws in the system)
