I used to work in this area as a doctor with experience in health care improvement. "The most under-used resource in the NHS is patients". Be armed with the information you should have. I know it, so should you.
Insist (insist, as Drs we can predict a lot about the duration of an acute illness but a few of us are...hmmm.....maybe arrogant??) you get the answers to the 4 questions below. If you don't, demand (really) to speak to the ward manager (nurse), the matron (nurse), the head of service (often a Dr), the clinical director (often a Dr), the chief nurse, the medical director, the chief executive in sequence. Don't be in hospital if you could be safely recovering at home.
The terms of the dedicated human-beings above the ward teams are usually 'bronze', 'silver' and 'gold' in command. They will all want the hospital to work but the invisibility of problems is real. So make them visible.
4 questions every patient/relative/carer needs to ask every day:
1) What is wrong with me and what are you doing about it?
2) What is happening to me today and why can't I go home now?
3) What do I need to be able to do/what do my tests need to show for me to go home?
4) On what day and at what time am I going home?
Write the 4 qns above down (along with every medication you are prescribed including ones you don't take because they make you ill and how they make you ill so you don't get prescribed them in hospital and get predictably ill) and tell everyone you know the 4 qns above and to write down their meds.
The NHS is good, but has massive variation in how clinical teams work. Take your own care of these inefficiencies and insist you are told the answer to the 4 ins above every day and that they are written down for you. There are many hospitals (no-where near enough) where there are cards by each bed for each human, filled in daily, answering the 4 questions.
If you, your neighbours, your relatives, your friends can go home at 5pm vs 9am the next day, at 11am instead of 4pm, at 10.45am instead of 12.30pm, the NHS will cope better and people will live who might otherwise have been harmed by waiting.
Write the 4 qns down. Share them. Safe discharge is set on admission.
