maternity hospital admittance form
Come up with the theoretical admittance form you believe to have been in use.
Did you ever stop and think that a lot of these documents we use today are designed primarily to support our computer systems. Back before the computer they did it differently ~ and to a degree much more economically from the standpoint of creating paper.
In 1961 you'd find your typical operation ~ an office, hospital, factory, whatever ~ would design their processes so they could economize on the amount of paper used (because there was little in the way of computer tracking anywhere), as well as security. You didn't want one form mixed up with another, and that with another ~ so you'd have one document follow the process all the way through. Multipart form sets were in common use ~ that's where you had copy A, copy B, copy C, and so on, and there might be instructions to send each copy to a different address/agency at the end of the process.
The modern "worksheet" with final document to follow method was rarely used.
I asked those in the know out there in Hawaii and they couldn't come up with information about some kind of worksheet used with this process. It was all one document from beginning to end and the beginning is in the BOH office itself where typing and rubber stamping was done.
