OB-42
Past Medical History
Form OB-42, Past Medical History, was used to record details of the
patient•s previous medical and surgical history up to the time of interview.
Information on childhood diseases and diseases of cardiovascular, respiratory
and digestive systems was included, as well as gynecological and venereal
diseases, other surgery, diseases of the renal and urinary tract, and other
disorders. First used as a pretest form in July 1961, the form was implemented
into the study in April 1962, replacing page 2 of OB-9. No revisions were made
on the form. Data were punched onto card 0342 in the master file (Table OB-42.1).
Some aspects of the patient•s past medical history were also recorded on form
OB-6, where radiological treatments and results of other treatments and exams
were recorded.
