Yes my story is similar. I have been an RN for over 30 years with background in nurse education, OHS, QA. (never too old Judy)
I was sent to one of our facilities to deliver some education. I found after a few short days that there were some problems with the electronic care planning/record systems. I have some IT background as well and am the only female owner of a fishing forum in Australia! I often wished that I could combine my 2 passions, nursing and computers into one job.
I was asked to project manage the piece of software that was in use and introduce it across several sites. Since then I have been involved in managing other projects such as piloting a medication management system, trialling various devices which have application in all sorts of other areas such as emergency fire and safety management, wound management etc. I have evaluated pieces of software and produced reports to board, worked with financial software and interfacing.
With the huge advances in technology and the movement towards e business/e health all healthcare facilities will need teams of people to manage the processes. The software is powerful and capable of re-engineering the clinical workflows and outcomes. Trends can be easily identified. A nursing background is essential to understand the complexities of care planning and documentation.
I too enjoy using my teaching, computer and clinical experience to assist staff to input meaningful data that will capture and reflect relevant and up to date information about patients.
Go to your health informatics department and introduce yourself and offer assistance. It is difficult to find people suitable and you may find yourself becoming a "super user" and helping others to navigate their way around. It is not always about a diploma/cert or degree.
It is an interesting field and it is not going away
