The impact of physicians' brief smoking cessation counseling: a MIRNET study.

Although many family physicians may discuss smoking cessation with their patients, few do so consistently. A common belief among many physicians is that such efforts will not deter their patients from smoking. Others believe the time commitment required for a successful intervention is excessive. The present study addressed the above issues by examining the effect of a 3- to 5-minute unstructured physician discussion encouraging smoking cessation with family practice patients. Cigarette-smoking patients of two busy family practices in southeast Michigan were randomly assigned to either a control group receiving routine care or an intervention group receiving, in addition to routine care, smoking cessation counseling from their physician. A third comparison group was drawn from smokers in practices not involved in delivering the intervention. Two hundred thirty-eight patients from the intervention group, 178 from the control group, and 47 from the comparison group were followed up with a telephone interview at 6 months. Intervention group patients made significantly more quit attempts than did those in the control group (P less than .001), which was similar to the comparison group. At the 6-month follow-up, 8% of intervention group members, and 4% of both the comparison and control groups reportedly were abstinent from smoking. Among those contacted at the 1-year follow-up, the respective percentages abstinent were 8%, 3%, and 4%. Although these differences in quit rates were not statistically significant, the findings suggest that physicians can positively affect patient smoking cessation. This intervention was feasible in busy family practices, highlighting its generalizability and applicability to other family practice settings in the United States.

Pathologist agreement in the interpretation of colorectal polyps.

Practicing physicians commonly perform flexible sigmoidoscopy in their offices. Polyploid lesions are frequently biopsied and sent to community hospitals for pathological interpretation. The pathologist's opinion often determines the course of medical follow-up for the patient, especially in cases in which early malignancy is suspected. This paper addresses the agreement of community-based pathologists regarding the interpretation of colorectal polyp pathology. Ten pathological slide sections were sent to 22 different community-based pathologists in southeast Michigan. These pathologists were asked to record their diagnosis of the specific histologies represented in each of the slides. The results indicated a high level of agreement of histologies in the dichotomous categories of hyperplasia versus adenoma. However, there was considerable disagreement on the presence of moderate or severe atypia. The results of this study indicate that clinicians performing biopsies on patients at risk for colorectal cancer should be aware of the potential for diagnostic variability among pathologists, and should plan follow-up strategies which may include seeking second pathological opinions when a significant patient management decision must be made.

Glycosylated hemoglobin levels and self-reported stress in adults with diabetes.

This study examined the relationship between glycosylated hemoglobin and self-reported stress in a sample of adult Type II diabetics. The study sample was drawn from participants in a randomized clinical trial of the comparative effectiveness of two oral antihyperglycemic drugs in the treatment of non-insulin-dependent diabetes. The 19 study participants were asked to complete a brief questionnaire on recent stress. Stress scores were then compared with levels of glycosylated hemoglobin. Correlations between glycosylated hemoglobin and stress scores were highly significant, a finding of particular clinical relevance in view of the relatively small number of participants. These findings suggest that sustained stress may contribute to poor glucose control in diabetics. Individuals interested in stress-related research may find glycosylated hemoglobin a useful marker of physiological stress.

Compliance with colorectal cancer screening in a high-risk occupational group.

A Detroit-area union offers an early detection colorectal cancer screening program consistent with that recommended by the American Cancer Society. Analyses compared men who have complied with the American Cancer Society recommendations with men who have not so complied. Older men, nonsmokers, and woodworkers were most likely to participate in all screening examinations. Primary reasons for nonparticipation were the belief that the examination was unnecessary, anxiety/affective concerns; and time/motivation problems. Particularly important to the success of such programs is a sensitive health education component to address personal concerns related to the procedure, and also the dissemination of information about the efficacy of the examination for early detection of colorectal cancer.

Serum cholesterol and colorectal polyps.

Colorectal cancer and hypocholesterolemia have recently been associated, and colorectal polyps have a known relationship with colorectal cancer. In order to establish further evidence regarding the nature of the serum cholesterol-colorectal cancer relationship, this study investigated the hypothesis that men with colorectal polyps would have lower serum cholesterol levels than men without polyps. Of the 1380 men screened by sigmoidoscopy for colorectal polyps, 246 had at least one polyp. The men with polyps were older than those without, and also had higher cholesterol levels, but after controlling for age, there were no serum cholesterol differences. These data suggest that low serum cholesterol is not etiologically linked to cancer. Analyses of potentially confounding variables showed smoking to be strongly related to the presence of polyps.

Physician accuracy in diagnosing colorectal polyps.

Since the medical management of persons with adenomatous colorectal polyps differs from that of those with hyperplastic polyps, accuracy of diagnosis is essential. Although many physicians have grown confident that their skills of visual diagnosis are adequate, few data exist to support this confidence. In order to examine the accuracy of physicians' judgments regarding colorectal polyp histology, the visual diagnosis of physicians experienced in endoscopy was compared with the histologic report. Eighty-one polyps were discovered by flexible sigmoidoscopy among 718 participants in a colon cancer screening program. Eighty percent of all polyps were detected accurately. The diagnostic sensitivity of detecting adenomas was 69 percent, while specificity (accurate diagnosis of hyperplastic polyps) was 86 percent, and there were an additional eight false negative and eight false positive diagnoses. Further analyses revealed that there are individual patterns of diagnostic mistakes made by physicians and that mistakes frequently are related to polyp size. These findings are particularly important in light of the expanding numbers of relatively inexperienced primary care providers performing flexible sigmoidoscopy whose diagnoses may be strongly dependent on polyp size.

Marital status, delay in seeking treatment and survival from breast cancer.

This study examined 10-year survival following a breast cancer diagnosis among 910 married and 351 widowed white women after adjusting for the effects of age, socio-economic status (SES), stage of disease and delay in seeking treatment for symptoms. All breast cancer patients were treated at M.D. Anderson Hospital and Tumor Institute in Houston, Texas between 1949 and 1968. Marital status, age, SES, delay and stage were all univariate predictors of survival. Widowed patients were less likely to survive than married patients. Multivariate analyses using a Cox regression technique did not detect an effect of delay on survival when stage and the other variables were included. However, marital status differences in survival remained when all the other variables were included in the model. These data suggest that marital status differences in survival cannot be accounted for by patient delay in seeking treatment for breast cancer symptoms.

Ethnicity, survival, and delay in seeking treatment for symptoms of breast cancer.

This study examined differences in 10-year survival rates from breast cancer among white, black, and Hispanic women controlling for the effects of age, socioeconomic status (SES), stage of disease, and delay in seeking treatment for symptoms. Breast cancer patients (n = 1983) treated at M. D. Anderson Hospital and Tumor Institute in Houston, Texas between 1949 and 1968, were followed for 10 years. Ethnicity, SES, stage of disease, and delay were all found to affect survival when considered separately. Black patients were less likely to survive than either white or Hispanic patients whose survival experience appeared to be similar. Multivariate analysis that used a Cox regression technique showed that ethnic differences remained when age, SES, stage, and delay were included in the model. In contrast, the authors could not detect an effect of delay on survival when ethnicity and all other variables were included. These data suggest that ethnic differences in breast cancer survival are not mediated by differences in delay in seeking treatment for breast cancer symptoms.
