Missed Orders; How do you do it where you work

Hi, sorry if this is long, need advice or a new job!
I work a 30 bed PCU/Ortho/general sugery floor. Massive problem with missed orders, so bad the boss is experimenting with the staffing to try and fix it. Our ratio was recently dropped to 5:1 days, 6:1 nights, with 3 cnas days/ 2 at night. A UC days, and at night till 11pm and a charge nurse both shifts. Very heavy unit.yesterday I had one CNA with 15 pts, only one of which was walkie takie, the rest 2 max assist and several inconinent We had the UC imput orders, each nurse checked, signed off at change of shift; nights were to do a 24 hr chart check. Major orders being missed; often. So we tried upping the nurse to 6:1, again, 3 aides. Trouble with that is we are expected to have perfect documentation, JCAHO perfect. We give massive amts of narcs and the pain evals alone can be a nightmare. One nurse was now off care doing chart checks and helping out. Trouble with that, too many fingers in the pie, the nurses who are conscientious and checking their charts as part of the job continued to do it, others just let someone else sign off for them, get the resource to pass meds, start IV's for them,basically sit back. A couple of things changed that contributed, they got rid of duplicate order sheets (money saver); they hired a new UC who had never done it before and gave her 5 days training. Not knowing a med from a lab, bound to be mistakes. And the fact that people who just sign away without checking and get away with it as no-one actually tells them when it gets caught! So both trials have been rough, I feel punished almost because Im one of the mugs who is anal about charts, so the extra nurse isnt much help to out I have an extra pt, or an aide with an impossible workload. So does anyone have any ideas, how does your unit do it, does it work?
