ABSTRACT
Two hundred forty-four consecutive diagnoses and procedures appearing on the patient billing records between June 1934 and September 1935 of a general physician practicing in rural southwestern Minnesota were compared with 286 diagnoses and procedures taken from the billing records of patient visits made over a 2-week period to a modern family physician practicing in a comparable rural community in southwestern Ohio. The most common items on the billing records of the physician of the 1930s were follow-up incision and drainage of abscess, 26 (10.7%); diphtheria immunization, 24 (9.8%); follow-up drainage for mastoiditis, 17 (7.0%); and scrotal tap for epididymitis, 14 (5.7%). Many of these patient encounters were at the patient's home. The most common items on the records of the modern physician practicing in rural southwestern Ohio were upper respiratory tract infection, 13 (4.5%); hypertension, 12 (4.2%); hyperlipidemia, 11 (3.9%); and history-taking and physical examination (adult), 10 (3.5%). This study suggests that there are great differences between the diagnostic profiles of the first third of the 20th century and modern family physicians. Many of the common diagnoses seen by the physician of the 1930s required a procedure to be performed. Many of the problems treated by the contemporary family physician did not even exist for the early 20th century general physician. Some of the differences between the modern physician and his predecessor can be explained by the introduction of antibiotics in the late 1930s and early 1940s.
