I spent a week in hospital with my then one year old son last autumn. Part of his treatment was intravenous antibiotics and most of the reason that we were there for a whole week was because the cannula kept failing and it repeatedly took them hours to find a doctor to put another one in. The longest wait was 12 hours meaning that he was behind 2 doses of antib's but there were several other times, once when a doctor couldn't manage it, asked a nurse - who wasn't allowed to do it, then wait several hours for another doctor. I could go on and on.
