One of the worse ones was when we admitted a long term facility, very contracted, trach/vent dependent patient in the ICU for "seizures". However, the only one who ever usually witnessed the so called seizures was her husband. That pt was in the ICU for a long time, mainly due to her many combabilities and for being so tasky (...and the nursing home she came from, refused to take her back due to the husband). He would micromanage everything (it would take almost 45mins to pass her meds, because he wanted it crushed and given in a certain order). When the case manager was able to find an accepting facility to transfer her out, the husband wasn't happy about it. So, the day before she was supposed to be transferred out, she mysteriously coded. The patient happened to be on con't video monitoring for agitation, and the husband was observed injecting something in the IV. At that point, risk management (who were already following that patient) was able to place a restraining visitation order against the husband.
