Nursing in Texas- Full Name legality on badge

Hello all,
Hope I am in the right forum?
I work in the state of Texas, and as I am sure like most states we are to have our name, first and last on our ID badges.
I recently recieved a very disturbing and disgusting phone call about a month ago, the man was describing some very sexual things when I picked up the phone. He stated his wife had a hysterectomy and I took care of his wife. He then said that he had to find out more about me, as he was very sexually attracted to me (in more disgusting terminology of course). I asked how he found me and he said "easy, I paid $9.95 online and got your address, phone number and credit score." I was terrified and hung up my phone and since I do not have caller ID I was unable to identify the number. Since then, this person has contacted me three times. I told him if he did it again I would call the police and since then nothing.
I went to hospital administration about this, as other female and male nurses have encountered the same thing. I was told there was nothing I could do.
We need to protect and advocate for the patients, but what about my protection?
I would like to know where I can go to advocate that we not use the entire first and last names on our badges. I live in a border city and with the drug cartel activity creeping over to my city I am terrified that anyone can get my information and come after me. This may not prevent these people from finding us healthcare providers and harassing us or worse, but it may make it harder to obtain personal information about us and our families.
What do you all think?
