Patient morbidity and some patterns of family practice in southeastern Ontario.

Over a 7-month period the trial version of the International Classification of Health Problems in Primary Care (ICHPPC) was studied. Ten community physicians reported 28 399 encounters wtith 11 437 patients. The overall distribution of health problems was comparable to that found in other North American studies. Some differences between the morbidity distributions in urban and rural practices varies from those of previous Canadian studies. Other differences between practices appeared to be related to the interests and training of the individual physicians. The workload of the physicians varied considerably. Many of the encounters involved problems for which there may be minimal benefit from medical intervention, and there was a large discrepancy in the frequency of follow-up visits for specified stable chronic health problems. The implications of these interpractice variations in the altering field of health care are discussed.
