Papanicolaou testing by physicians in manitoba: who does them?
Pap testing is one of the few effective preventive health practices available to primary care physicians. Yet we know little about how well this procedure is being done. Using data from the province of Manitoba's universal health insurance plan for the years 1976, 1978 and 1982, we determined the proportion of all Pap tests of women over 25 years of age performed by the various physician specialties; the percentage of physicians in each specialty who performed tests; and the mean number of tests per specialty group. We also determined the mean number of tests by age and training of the physician. The number of physicians performing Pap tests increased from 749 in 1976 to 780 in 1982. About 2% of Pap tests performed in the province were done by internists, 5% by general surgeons, about 33% by obstetrician/gynecologists, 40% by urban general practitioners, and 22% by rural general practitioners. Other physicians accounted for less than 0.2% of all tests. The mean number of Pap tests performed increased with increasing physician age up to age 60 and declined thereafter. Manitoba-trained physicians performed the highest rate of Pap testing, and this pattern was maintained over time. In 1982, only 22% of internists, 29% of general surgeons, and 78% of family physicians/general practitioners were performing tests. These results raise the question of why a significant number of physicians are not carrying out this effective preventive health practice.
