I've looked at my own before now - mainly to see if things like my temperature, blood pressure, pulse were getting back to normal to get an idea as to whether I was getting better and might be able to be discharged as they usually have it in the chart.
When I was last in for a stay (infected gallbladder) a nurse came and put my notes by my bed ready for the Dr's rounds. I was having a bit of a nose, mainly looking to see if there was a scan picture of when they scanned for gallstones (out of morbid curiosity to see what was causing so much pain) but there wasn't one so was looking at other scan pics of my insides and a nurse said to make sure I put them back before the Dr appeared as he wouldn't like it.
I do get a lot of comments though as I have lawyer (I'm sure it's highlighted or something!) on my medical records, I find it such a shame they think like that though I can see why.
I was kept in for a test to be done I didn't really need once. I questioned why if it was very unlikely it would show up anything (blood clot test, I had swelling in both legs and they said very unsual for a blood clot to affect both). I said I was happy to trust their judgment (ie it being very unlikely) and go home but they said they wanted to do it as I'm a lawyer. I pointed out I'm a property lawyer and am not a fan of the compensation culture and adverse affect it has on defensive medicine but they insisted on doing it.
