My mother was very poorly, terminally ill, a couple of years ago. After a serious lack of communication on the ward, I emailed PALs late on the Friday evening to be told by reply of email that someone from PALs would look at my comments in FOUR days. So I found the name of the CEO and emailed him on the Friday night, he replied to me by 08.00 on the Saturday and when I went to visit my mother at 12.00 midday, the most senior person on duty met me and the problem was resolved.
Email the Chief Executive now, cc the Consultant, explain what's happened and I imagine you'll get a reply soon. Please take someone calm with you to any meeting, keep notes and do a timeline before you go in - i.e. when did you husband go in, dates of ops and medications, who said what and when. This will take a little time, but will give you a good basis for discussion. Emails are good - they provide an audit trail, whereas phone calls can be mislaid.
I'm a nurse, my husband a doctor ... and all this guff about 'gallows humour' is unacceptable. If you could hear the doctors talking so, I suspect, could others, and it showed a lack of honesty, dignity and sensitivity.
Hope you get your answers, I'm sure you will. ?
