I am an overnight pharmacist at a 450-bed hospital. It can get VERY busy. I only have one tech and the nursing staff at my hospital is horrible. i spend 90% of my night answering the most ******ed questions. Anyhoo, I have been here a year and I made my first error. I received an antibiotic order from the nursery. The order was for Vanco, Claforan and a TPN. I started working on it immediately. Checking doses, volumes, concentrations etc. Within 2 minutes the nurse calls me "we just scanned you an order that is super stat!!!! we need it right away!! did you get it!?"I was slighly annoyed but understood the urgency. Obviously the call distracted me, i told the nurse we would have everythign ready in 30 minutes.3 minutes later another nurse calls, "i know we already called you but this really needs to get up here sooner than 30 minutes. The doctor is stand right here, blah blah blah...."So now I am officially pissed and I told the nurse that this is the second interruption I have had trying to process this order. I kindly asked her to not call me anymore. I hung up and ironically I said to my tech "see, this is how mistakes happen!"Long story short, the neonatologist wrote for 100mg/kg of vanco, not 10mg/kg. I missed it too, with all the phone calls I probably bypassed the alert on the computer. The baby was fine when all was said and done but the part that gets me is that they didnt hang the drug until 2 hours later because there was no line access. I know this wasn't entirely my fault but I hate when stuff like this slips past me.
