Hello, My sister, Raina Thomas DOB 10/24/73, was a patient in the ER and ICU on Saturday August 28 and Sunday, August 29, 2021. She felt unsafe and received hostile communication from RN nurse Mike. I called to address this and spoke to Mike's supervisor, RN Aurora. I was never given last names so I cannot include those. I explained to Aurora on Saturday evening that the hostile and at times aggressive and passive aggressive treatment my sister described and I needed it addressed as soon as possible as it is unacceptable. I also requested a change in nurses for my sister which Aurora said was not feasible. Aurora was professional throughout my conversation with her. She attempted to justify Mike's care as excellent and someone she would want taking care of her family. She stated she would address Mike's behaviors and speak with my sister that evening. I explained that if Mike's inappropriate patient care continued I would move my grievance forward and notify the board as patient's must feel safe. Aurora never followed up with my sister that evening. She may have been dealing with emergencies and I understand that. My sister kept me on the phone and I witnessed an interaction with RN Mike after asking that the hostility be addressed and it continued. At that point I directed my sister to request another nurse. The nurse who then helped my sister, although my sister does not remember her name, was wonderful per my sister's report. I think it is vital that a patient be treated with care and respect and feel safe. The treatment provided by RN Mike needs to be investigated because as soon explained to Aurora it would be uncommon for this to be an isolated event.
