Patient 1991
DSN: CC37.NAMCS91.PATIENTS 1991 Format For Patient Micro Data Tape This section consists of a detailed breakdown of data tape record, providing a brief description of each item of data included in the records. The data are arranged sequentially according to their physical location on the tape record. Unless otherwise stated in the "item description" column, the data are derived from the Patient Record Form (page 7). The AMA and the induction interview (reference 3) are alternate sources of data, while the computer generates other items by recoding selected data items.
