If someone comes into hospital trusting the opinion of their doctors that this procedure is going to result in an improvement in their quality of life, and then instead of returning home better they have extended complications, it is just awful. I’m not sure how else to explain it - but consider if your mother/father/partner went to theatre for an elective joint replacement and then instead of being back at it in a couple of months, better than ever, was still in hospital undergoing rescue surgeries and strong antibiotics
