Some advice

I have decided to go back to school after 31 years in the OR to obtained my BS. The trouble I am having is the area that I want to concentrate in. I am getting to that point in my life where I don't want the long hours that I have working in the OR and want something I can enjoy working only the 40 hours, or less, a week. I plan on cutting down quite abit at 62 , in 7 years. I have looked at BSN and BS in Healthcare Admin. I have also looked at Nursing informatics. I love to work with computers and have had one since around 1980 when I had a IBM with a 8088 processor. The one thing I have noticed when researching programs was that almost all of them was for Masters programs and not BS. What's up with that? Are there any programs out there that are batchelors programs or not? I don't plan on teaching at all so I don't think a BSN is for me so maybe a BS in Admin. We have been using computerized nursing documentation for over 8 years and there has been numerous times I wanted to re-write the program because it lacked alot of features I think nurses would like to make charting more interesting. Any advice on where to look? I guess I could go one way and end up with a MS in NI, but that would take a long time. Thanks
