Colorectal cancer screening by primary care physicians in Texas: a rural-urban comparison.

BACKGROUND: Little is known about colorectal cancer (CRC) screening practices of primary care physicians (PCPs) in rural versus urban locations. METHODS: The authors surveyed 3,380 PCP members of the Texas Medical Association (TMA), stratified by specialty and rural/urban status. Factors associated with PCPs' self-reported practices of CRC screening by fecal occult blood test (FOBT) and/or flexible sigmoidoscopy (SIG) were examined using chi-square tests and multivariate regression. RESULTS: Over 80% of both rural and urban PCPs reported CRC screening with the FOBT, while 70% reported screening with SIG. Many reported doing FOBTs in the office versus using the take-home kit. Variations were found in recommended ages and screening intervals among all respondents. CONCLUSIONS: Geographic location was less important than knowledge and attitudes in predicting PCPs' CRC screening practices. More specific education regarding CRC screening guidelines needs to be directed towards all PCPs.

The association of race/ethnicity, socioeconomic status, and physician recommendation for mammography: who gets the message about breast cancer screening?

OBJECTIVES: This study investigated the association between physician recommendation for mammography and race/ethnicity, socioeconomic status, and other characteristics in a rural population. METHODS: In 1993 through 1994, we surveyed 1933 Black women and White women 52 years and older in 10 rural counties. RESULTS: Fifty-three percent of the women reported a physician recommendation in the past year. White women reported recommendations significantly more often than did Black women (55% vs 45%; odds ratio = 1.49). Controlling for educational attainment and income eliminated the apparent racial/ethnic difference. After control for 5 personal, 4 health, and 3 access characteristics, recommendation for mammography was found to be more frequent among women who had access to the health care system (i.e., had a regular physician and health insurance). Recommendation was less frequent among women who were vulnerable (i.e., were older, had lower educational attainment, had lower annual family income). CONCLUSIONS: Socioeconomic status, age, and other characteristics--but not race/ethnicity--were related to reports of a physician recommendation, a precursor strongly associated with mammography use. Efforts to increase physician recommendation should include complementary efforts to help women address socioeconomic and other barriers to mammography use.

Colorectal cancer screening by primary care physicians in two medical care organizations.

The objectives of this study were to (1) evaluate self-reported practices of colorectal cancer (CRC) screening among primary care physicians (PCPs) in medical organizations and (2) identify factors associated with screening performance. We surveyed a census sample of 204 PCPs from two medical organizations in Houston, TX. Outcomes were PCPs' self-reports of screening with fecal occult blood test (FOBT) and/or flexible sigmoidoscopy (FS).2-7 Independent variables included physician demographics, perception of screening efficacy, level of agreement with screening guidelines, and perceptions of screening barriers. Variables were compared using Student's t-tests, Chi-square, and Fisher's exact tests. Regression was used to examine factors associated with PCPs' reports of screening. Our response rate was 56% (n = 115). Many PCPs reported recommending and/or performing/ordering screening with both FOBT (82%) and FS (87%). They more often reported believing that FS was "very effective" for reducing mortality than was FOBT (76% vs. 37%). Physicians perceived that barriers to patient compliance with CRC screening were stronger than barriers to making screening recommendations. Significant test-specific differences in reported barriers to screening were found. Results revealed high awareness and self-reported practice of CRC screening in this study population. Further examination of how barriers influence CRC screening practices by PCPs in medical organizations will be important for improving population screening rates.

The role of physician recommendation in women's mammography use: is it a 2-stage process?

OBJECTIVE: To explore the use of a 2-stage model in explaining the role of physician recommendation in women's use of mammography screening and to provide an integrated framework for understanding the mammography-use process. METHODS: Data on 1,301 women aged > or =52 years from the North Carolina Breast Cancer Screening Program (NC-BCSP) questionnaire were combined with information from 91 of their physicians from the North Carolina Medical Board. A 2-stage system of equations using women's characteristics (demographic, health, access), physicians' characteristics (demographic, practice), women's beliefs, and women's report of a physician recommendation was created and statistically tested. The model was estimated using 2-stage logistic and probit estimation. RESULTS: The 2-stage approach produced different results compared with the single pooled model. In the second-stage mammography-use model, younger age, family history of breast cancer, and a woman's having ever requested a mammogram retained significance (P < or = 0.05) in addition to the predicted value of physician recommendation obtained from the first stage. Women's characteristics significantly associated with physician recommendation in the first stage included some access, health risk, and demographic variables as well as physician age and race (P < or = 0.05). CONCLUSIONS: A 2-stage model for estimating mammography use among women with regular physicians may be more informative than a single model. These results imply that programs designed to increase mammography rates should focus on ensuring appropriate physician recommendations in addition to encouraging women to request screening. Future research should consider using an integrated framework for evaluating utilization of mammography and other preventive services.

Average-risk screening: is public policy compatible with individual needs?

The issue of the appropriateness of population-based screening for colorectal cancer has been much debated in the literature. The purpose of screening is to find early-stage disease among average-risk members of the population so that timely treatment may be implemented and mortality reduced. The goal of public policies regarding screening should be to facilitate this result. The adequacy of current public policy for reduction of colorectal cancer mortality is the main focus of this article.
