Probably picking up on a point thats far from key. But every ward i've worked on I've had patients who are 'frequent flyers'. There was on chap on my acute medical respiratory placement who came in every couple of months with an infective exacerbation of COPD. Every time he was greeted like a long lost son, given a gentamycin nebuliser and discharged a few days later in good shape. Its how we expected it to go every time. Until, eventually the gent nerfed his kidneys and he died on that admission. It took a lot of time to process that mentally because of the usual 'plan' of his admissions. it was inconceivable that he would be more than a little unwell.
