Thankfully, I have never made a mistake in type 4 and hopefully never will. To be fair, I actually think they are incredibly rare.
Unfortunately, I have made mistakes in the first three categories and although nobody really likes talking about their own mistakes, they are probably fairly typical of slip-ups made by young doctors like me so I thought you might find them interesting.
As a very junior doctor I was on a ward round with my consultant and a final-year medical student. The consultant said that he wanted a transfusion for Mrs X and asked me to take some blood to send to the lab so that we could confirm which blood group she was.
After the ward round, I asked the medical student how confident he was in taking blood. He was happy to give it a go, so I asked him to go off and take some blood from Mrs X. He came back proudly ten minutes later with the blood and I labelled the forms and samples of blood and sent them to the lab. The next morning as we got to Mrs X on the ward round, she was sitting happily in her bed with her second bag of donated blood running through into her vein. My medical student suddenly turned very pale. ‘Is that Mrs X?’ he trembled. ‘She’s not the lady I took blood from yesterday. I took blood from that lady opposite.’
Now this could have been an absolute disaster. Giving the wrong blood group to a patient can make them very ill and potentially kill them. I had signed the form stating that the blood taken was from Mrs X and therefore would have to take responsibility for the error. The medical student should have checked who he was taking blood from but ultimately, I was responsible for supervising him so again the buck would have to stop with me. Fortunately, Mrs X and the patient from whom my dopey medical student did take blood had the same blood group so no harm was done. I plucked up the courage to tell my consultant what had happened. I was fully expecting the shit to hit the fan, but instead he stuck a fatherly arm round my shoulder and said, ‘Don’t worry, Ben, I made far worse mistakes when I was a junior. You got away with this one, but just make sure you learn from it and don’t let it happen again.’
I saw a middle-aged man complaining of headaches. His headaches were fairly nondescript with no symptoms of weakness in his limbs or problems with his vision. He hadn’t banged his head and the only thing of note was that he was feeling a bit tired and stressed out at work. I gave him a really thorough examination and documented everything very clearly in the notes, but basically reassured him that there wasn’t likely to be a serious underlying cause of his headaches. A week later he was found collapsed at home and was found to have a brain tumour. His headaches were almost certainly related to this and I had missed it. However, during our consultation, I took him seriously and gave him a really thorough check-over. I also asked him to come back if his headaches weren’t resolving. He is recovering slowly in a specialist neurology hospital after some quite major brain surgery.
Some time ago I saw a woman with some odd tightness in her chest. She was well in herself and only in her mid-fifties. She told me that she had the symptoms when she went into town shopping and wondered whether they might be due to anxiety. I asked her lots of questions about the pain to make sure it didn’t sound as if it was because of problems with her heart or lungs. I also gave her a thorough examination, but couldn’t find anything wrong. I had a long chat with her about relaxation techniques and breathing exercises and told her to come back if the pain got worse. Three days later she collapsed with a heart attack. Again I had missed the diagnosis, but sometimes heart problems can present oddly and perhaps many other doctors would have done the same as me. In hindsight perhaps I should have done a heart scan and ordered some blood tests but these might not have made a huge difference. My real error in this case was that my documentation in the notes was really poor. I didn’t write much about the pain she had or the examination I did. Legally, I hadn’t covered myself at all.
