Unfortunately, there’s nothing good that can come out of an “interview” for you & lots of bad things could happen.
Most states notify & can require your participation just by sending a mailed letter to the address on file for your BON. When the letter comes, you hire the attorney & the attorney can usually determine what the complaint is about before the interview. There’s often a legally-required list of questions that you’re required to answer before the interview & you should be filling that out with your attorney’s advice. Lots of pitfalls there. A literal minefield.
Further, many investigations involve multiple agencies that each try to do investigations themselves and they can and do use pieces of your statements to other agencies to build a case against you. Many states have an agency that represents older or “vulnerable” adults, an attorney general, and various departments like CMS that are all effectively “law enforcement” and have the ability to bury you professionally.
In the investigation that I was subjected to, my first notification of a complaint was from that agency that was charged with protecting the “vulnerable” adults in my state, requesting a statement right then, over the phone. That conversation was very friendly and low-key, and I simply refused to make any statement without an attorney’s advice. That was followed by a letter from the board, with a list of questions that I was required to answer and swear to. When my response (with the attorney’s help) was sent, the BON and this other agency were conducting parallel investigations, and sharing information.
Fast-forward (or more like slow-forward) seven months - and a few days before my in-person meeting with my attorney and the board’s investigator, additional details were revealed to my attorney. It turned out that the complainant in my case was a serial complainer who had made several unfounded accusations before mine, and a couple more complaints after. He bragged about getting me fired and threatened an aide with getting her fired too if she complained about his sexual assault.
Even after the investigation by the BON was completed and found to be unsubstantiated, the agency that was charged with protecting vulnerable adults closed their investigation with the statement that the allegations were neither “founded nor unfounded” - without ever talking with me.
Further, my attorney explained that nothing in either investigation precluded the attorney general from filing a criminal complaint anywhere in the process - and using any data or statements gathered from any source against me.
The entire process is incredibly prejudiced against the nurse. Yeah, you have a right to remain silent as an American, but you lose that right if you want to remain a nurse. You have a right to confront your accuser, unless they’re “vulnerable”.. My accuser was the polar opposite of “vulnerable”, but the definition of vulnerable under the law isn’t the same as any sane person would give.
TLDR: No statements at all without the advice of an attorney.
