To game over. GOOD JOB! It sounds like you made the right moves, filing a report, notification and all. It sound to me like that the other nurse has a little phobia about making reports, if she saves them only for falls.
Incident reports in my hospital are called variance reports. This puts an emphasis on a "variation" from the normal course of patient care. This has decreased "finger pointing" between depts. and staff members significantly.
I had a pt on gen. med. floor choke on a piece of chicken that had been readied by one of my most trusted aids. It turns out there was a small bone, and she sustained a esophageal tear. Thanks in part (I think) to my documentation, the legal issues were slight, despite a poor outcome.
To michelle126, at our hospital, we have, at least in OR, a form called a safe medical device variance. This is somthing we make out when a piece of equipment fails during a case that changes the course of pt care. We also make out the other variance sheet as well. We are lucky we also have a great biomedical dept that works with our equipment.
I agree with you all, document, document, document. This protects us initially, and if your administration is really reading those variances, they will start or change things that will protect your pt's as well in the future.
