[A model for different types of computers for recording, managing and evaluating data of middle ear operations...

A system is presented for recording, managing and evaluating data which is so simple that the clinician is able to handle it. The recording of data is done by marking on preformulated questionnaires without any coding of information by the doctor. From the documents, the key-punch operator then makes the punch cards (the alternative: marking documents that can be read directly by an optical mark page reader). The managing of data is done by an own program written in FORTRAN. It creates a tape-sentence of equal length and fixed format for each case. That means each case would contain the same variables, and the order of variables within each case would be the same. The ordering is done by means of an identification code which is derived from the employee numbering system and which makes it independent of all archive-based records. The evaluation is carried out by means of a data processing system which is available for most computers (SPSS). The preformulated questionnaires used for recordings, the program for managing the data and the evaluating procedure punch cards are described. All will be sent by demand.
