The other evening when I was working my evening shift as an LPN a resident went out an alarmed door in the dinning room .No staff where present at the time. The alarm sounded at the nurses station and the unit secretary sent staff to check it out. A confused resident from my unit had gone out looking to go home. . Another nurse working on a unit closer to the dinning room informed me of the incident. Two CAN's where able to redirect resident back into facility from what I was told. The CNA then brought the resident back to my unit .I immediately went to the unit manger on duty and informed her of incident and asked her how to get a wandergaurd for resident. She did not know and stated she will call our rehab nurse as the rehab nurse is the person who has our alarms. I also reported the incident to the nursing supervisor on duty a short time later. We discussed alarms and what doors have alarms along with the wandergaurd system . I was later informed by one of them that the dinning room door does not have a wandergaurd alarm. The only door having a wandergaurd system was the front door. I did not think of doing an incident report and both supervisors did not inform me to do so. So two days later on my day off I get a call from the ADON saying she is doing a VA report and asks me some questions. I informed her I had reported it immediately to my unit manager . She called me back a short time later and asked that I fill out incident report. I offer to come in and do it right away and she informs me I can do it the next day when I come to work. Again she asks me if I reported it to anyone. Again I tell her I informed the unit manger right after it happened. She states " Oh she is new " So the next day when I get to work I fill out the incident report and then talked to my unit manager. She shares with me the internal investigation that the ADON has done. She informs me it is a learning experience for all of us. Here is what ADON has document in her report on me. Team Leader- was notified of incident between 4-4:30pm. She did not do an incident report or called in the potential VA. She was educated that there needs to be documentation and VA called in, she was informed to notify the supervisor. She was told she needed to come in and complete the incident report. So it looks like I did nothing. I am angry and feel I should talk to DON on this matter. PS - Internal conclusion : This is not a VA as staff responded to door alarm.
