We can change any result in our LIS, but it keeps track of it, shows who did it and on what date, and throws an exception. We would always have a comment attached why the change had to happen. But nothing can ever really be "deleted". While we're on a physician complaint kick...a surgeon called last Saturday SCREAMING that we did not have a certain size of tissue in Blood Bank that he needed for a Sunday surgery. He said he is filing an incident report and slammed the phone down. I wish he had a chance for us to tell him: 1. He used the last one the day before, Friday afternoon after 4 pm. Unless the Tissue Fairy comes overnight... 2. Hospitals are open on weekends, most companies are not. 3. This particular piece of tissue costs about $20,000, so we can't really keep multiples of every size in stock. 4. This is a new tissue, we've just had it for a couple months...how did you save lives before it was invented? OK, rant over. For now.
