First of all, In your scenario, would fax machines still be working? Because that would simplify getting orders off to the appropriate departments.
I was such a "dinosaur". I started my RN career when we had no computers; all orders were entered by hand, and nurses drew all the lab in our NICU. Including and made our own slides when drawing a CBC. When our computers went down once, it was a colossal mess.
We still had our paper order sheets, and the unit secretaries hand-enterd each patient's lab draw orders. Doctors' med. orders were carried to the pharmacy by our PCTs, and nutrition orders were called to Dietary.
I worked briefly on our hospital's telephone triage line when the hospital computers went down one night. They were down for 7 hours. We hand-entered all calls, fax information, etc. Then we called the families back, and again hand-wrote everything pertinent. We had hard-cover copies of all the protocols we used, and we referred to them for the appropriate guidelines and responses to give.
I was working with another RN @ the time. She told me that we would turn over all the handwritten entries to the day shift Coordinator, and she would transcribe them when the computers came back online. Well they did come back on 2 hours before the end of our shift, so I volunteered to start transcribing all our calls into the computers, since we weren't busy at the time.
The thanks I got? The RN I worked with told the day shift coordinator I typed too slowly, and she didn't understand why it took me so long to type in the calls. We had about 20 calls that I transcribed. oh well.
