Don't freak out, it will be okay. You can only do what you can. Take your time. They will look for the following things in personnel files:
What does your facility policy and procedure on abuse say that you are going to do to screen new employees for hire? Whatever your policy says, is what they will look for.
Criminal record check done and back on the file within 30 days.
Sworn statement prior to the criminal record check being sent.
License verification and CNA certification: They will want the printed verification from the website for license look-up. If your policy says that you are going to do this prior to offering the job, or hire, then it must be dated (computer date) prior to hire or the offer.
Two reference checks or two valid "efforts" that you have tried to get a reference. If the person has never worked anywhere before, then personal references will do.
If it is just a standard survey then they will request a list of employee files hired within the last four months. If it is licensure then it will be for the past 2 years. If someones license has expired during that time, they will want to see that the license was verified upon hire and also that you verified the license again when it was renewed.
If it is licensure, then they will want to see in the employee file evidence of training on the mandated/required inservices (abuse, resident rights, ect) that need to be done on orientation and annualy.
Job descriptions in each file, signed and dated.
Go through the files and see what you are missing and get it done. You can then get the information, though it may be late, it will still be there, and formulate a plan of correction so that it does not occurr again. You still may be cited, but if you have a plan of correction in place (addressing all 5 points) then it could be considered past non-compliance, because you identified the situation and put a plan of correction in place. Make sure your allegation of correction date is prior to the surveyors coming and make sure that any files from that date forward have NO problems or that will invalidate your plan of correction.
You should not be attacked by anyone. Just answer honsetly, and if you don't know, just say so and go find out.
