We have two systems running, in the form of the electronic copy and the good old hard copy printed out and filed with the job card and electrical safety test. Covers both bases if one gets lost.
We are going towards an integrated system that all our work sheets and test results as well as our database of equipment is held electronically within the server (well thats the theory anyway). The paperless environment were the staff on the wards send us an email which will automatically issue a job and then we do our stuff. Will keep you informed if it ever works (I wont hold my breath).
We also use the scales method for the renal equipment as we are removing a weight and like to keep copies, that its doing what it says on the screen. Good set of scales attached to the computer that gives us a weight loss over time.
