Early detection and screening for ovarian cancer: does physician specialty matter?
OBJECTIVE
To examine physician factors associated with ovarian cancer screening.


METHODS
Postal questionnaires to Maryland primary care physicians. Bivariate tests for statistical significance used X-Square and Student's t tests. Multivariate analysis and logistic regression were used to analyze responses based on specialty type, gender, and work experience.


RESULTS
Fifty-six percent of the 375 were male, 44%, females; 33%, OB/GYN; and 67%, family/internal medicine (FM/IM). The mean age was 47 and the mean number of years in practice was 16. OB/GYNs provided more ovarian cancer counseling, OR 2.64 (CI 1.55, 4.48) and were more likely to respond correctly to knowledge questions--i.e., reduction of ovarian cancer risk with oral contraceptive (OCP) use than IM/FM, OR 8.57 (CI 3.54, 20.8). Overall, there were few gender differences in approach to evaluation, but male physicians were less likely to be aware of the relationship of OCP use to ovarian cancer risk than females, OR 0.48 (CI 0.25, 0.91). IF/FM physicians were less likely to order CA-125 for patients (of any age) based upon symptoms of bloating or physical examination alone. OB/GYN physicians, OR 4.77 (2.73, 8.34) and physicians with > 15 years in practice, OR 2.79 (1.46, 5.35) attended more meetings on ovarian cancer than non OB/GYNs or those with less experience. Although 74% indicated access to the Internet, just 16% to 26% used the Internet for cancer information; OB/GYNs used the Internet less frequently than FM/IMs, OR 0.53 (0.28, 0.97).


CONCLUSIONS
Specialty was more predictive of knowledge, approach to evaluation, and counseling than gender or experience.
