Recruiting minority cancer patients into cancer clinical trials: a pilot project involving the Eastern Cooperative Oncology Group and the National Medical Association.
(57/50730)
PURPOSE: Minority accrual onto clinical trials is of significant interest to cooperative oncology study groups. The Eastern Cooperative Oncology Group (ECOG) conducted a study to identify barriers and solutions to African American accrual onto clinical trials. METHODS: We hypothesize that the National Medical Association (NMA) might provide insight into ways to increase minority participation and that ECOG might facilitate that participation. Four sites were selected in which NMA chapters existed and ECOG main institutions with less than half of the corresponding percentage of minorities in their communities entered trials for 1992. Fifteen workshops were conducted using discussions and open-ended, self-administered questionnaires. RESULTS: Seventy percent of NMA physicians cited mistrust of the research centers, fear of losing patients, and a lack of respect from ECOG institutions as the most important barriers to minority cancer patient referrals, compared with 30% for ECOG physicians. Sixty-nine percent of NMA and 43% of ECOG physicians cited a lack of information about specific trials. Nearly half of NMA physicians (47%) cited a lack of minority investigators as a barrier, compared with 4% of ECOG physicians. Solutions by both groups were improved communication (73%) and culturally relevant educational materials (40%). ECOG physicians cited more minority outreach staff as a potential solution (22% v 6%). NMA physicians cited increased involvement of referring physicians (44% v4%). CONCLUSION: NMA physicians who serve a significant sector of the African American population demonstrated a willingness to participate and work with a cooperative group effort to increase participation of minority patients and investigators.

Attitudes, knowledge, and risk perceptions of women with breast and/or ovarian cancer considering testing for BRCA1 and BRCA2.
(58/50730)
PURPOSE: This study examined baseline knowledge, beliefs, and risk perceptions among a group of 200 women with breast and/or ovarian cancer who participated in a trial designed to improve decision making about genetic testing for BRCA1 and BRCA2. PATIENTS AND METHODS: Women were identified by self-referral, physician referral, and tumor registry extraction and invited to participate in a randomized trial in which testing for BRCA1 and BRCA2 was offered free of charge. Subjects completed baseline questionnaires and interviews that assessed knowledge, attitudes, and perceptions of risk of having an alteration in BRCA1 or BRCA2. RESULTS: Sixty percent of women overestimated their chances of having a BRCA1 or BRCA2 mutation compared with estimates from a BRCA1/BRCA2 risk model. Women who have at least three relatives with breast or ovarian cancer were one third (95% confidence interval, 0.2 to 0.6) as likely to overestimate their risk of having a BRCA1 or BRCA2 mutation compared with women who have two or fewer affected relatives. Knowledge was limited about BRCA1 and BRCA2 mutations and cancer risk associated with gene mutations. Eighty-four percent of the women indicated a probable or definite interest in testing. CONCLUSION: A high proportion of the high-risk women in this study had knowledge deficits about BRCA1 and BRCA2 and overestimated their risk of having a mutation. Although some degree of caution should be used in generalizing the results of this study to practice settings, the data provide insight into the challenges clinicians will face in communicating with patients about cancer genetics.

Stress and morale in general practice: a comparison of two health care systems.
(59/50730)
BACKGROUND: Poor morale and high levels of stress among general practitioners (GPs) are causing concern. Little research has previously been carried out to study possible differences in morale and stress between GPs working in two different but geographically similar health care systems. AIM: To compare perceived levels of stress and morale between GPs working in two different health care systems--one having a state monopoly (Northern Ireland) and the other having mixed private and state funding (Republic of Ireland)--and to look for factors that might help explain any differences in stress levels and morale between the two systems. METHOD: Anonymous and confidential questionnaires were sent to all 986 National Health Service (NHS) GPs in Northern Ireland (NI) and a random sample of 900 GPs in the Republic of Ireland (ROI). A common set of core questions on demographic details, partners and work patterns, perceived levels of stress and morale, safety, violence, and complaints were asked. RESULTS: Response rates were high in both areas: 91% in NI and 78% in the ROI. GPs in NI had significantly higher stress levels and significantly lower levels of morale than GPs in the ROI. The NI sample expect matters to get worse over the following year. Doctors in the ROI were more likely to be single handed and to work from two sites. Also, more GPs in ROI had fears for their safety and had been the subject of physical violence, but fewer had received complaints and medico-legal actions than in NI. CONCLUSIONS: A significant proportion of both groups of doctors report feeling highly stressed but GPs in NI appear more unhappy and have a poorer outlook for the future. It is suggested that the structure, management, and expectations of the NHS have taken a severe toll on its GPs, whereas a system in which doctors have less practice support but more control is good for morale.

Validity and reproducibility of a quantitative food frequency questionnaire for a cohort study in Japan.
(60/50730)
BACKGROUND: A self-administered quantitative food frequency questionnaire (Qx) was developed for a population-based cohort study on cancer in Takayama, Japan. METHODS: The Qx was tested among 58 male and 59 female volunteers. Average daily nutrient intakes for the previous year calculated from the Qx were compared with those from 3-day food records and four 24-h recalls. The Qx was also validated among 37 volunteers by comparing the nutrient intakes calculated from the Qx with 12 1-day food records during a year. We also calculated the intra-class correlation coefficients for various nutrients between the Qx and the second Qx administered by the same volunteers 1 year after the first survey. RESULTS: Pearson correlation coefficients between total energy from the Qx and 3-day records were 0.38 for men and 0.25 for women and those between the Qx and 24-h recalls were 0.19 and -0.02 for men and women, respectively. Correlations between the several nutrients from the Qx and 3-day records ranged from 0.2 to 0.5 for both men and women. These correlations after energy adjustment ranged from 0.2 to 0.6 for men and from 0.1 to 0.7 for women. In general, the correlations for various nutrients between the Qx and 12 1-day records were higher than those described above. The intra-class correlation coefficients ranged from 0.46 to 0.78 in men and from 0.36 to 0.67, except for vitamin C in women. When the information on portion size was excluded, almost all of the above indices showed somewhat lower figures. CONCLUSION: These results suggest that our food frequency questionnaire with portion size information can be used to estimate nutrient intakes of each individual. (+info)
A comparison of the use, effectiveness and safety of bezafibrate, gemfibrozil and simvastatin in normal clinical practice using the New Zealand Intensive Medicines Monitoring Programme (IMMP).
(61/50730)
AIMS: Because of the importance of treating dyslipidaemia in the prevention of ischaemic heart disease and because patient selection criteria and outcomes in clinical trials do not necessarily reflect what happens in normal clinical practice, we compared outcomes from bezafibrate, gemfibrozil and simvastatin therapy under conditions of normal use. METHODS: A random sample of 200 patients was selected from the New Zealand Intensive Medicines Monitoring Programme's (IMMP) patient cohorts for each drug. Questionnaires sent to prescribers requested information on indications, risk factors for ischaemic heart disease, lipid profiles with changes during treatment and reasons for stopping therapy. RESULTS: 80% of prescribers replied and 83% of these contained useful information. The three groups were similar for age, sex and geographical region, but significantly more patients on bezafibrate had diabetes and/or hypertension than those on gemfibrozil or simvastatin. After treatment and taking the initial measure into account, the changes in serum lipid values were consistent with those generally observed, but with gemfibrozil being significantly less effective than expected. More patients (15.8%S) stopped gemfibrozil because of an inadequate response compared with bezafibrate (5.4%) and simvastatin (1.6%). Gemfibrozil treatment was also withdrawn significantly more frequently due to a possible adverse reaction compared with the other two drugs. CONCLUSIONS: In normal clinical practice in New Zealand gemfibrozil appears less effective and more frequently causes adverse effects leading to withdrawal of treatment than either bezafibrate or simvastatin.

Enhancing the identification of excessive drinkers on medical wards: a 1-year follow-up study.
(62/50730)
This paper describes a 1-year follow-up study examining whether hospital ward doctors and nurses continue to take quantitative alcohol histories and provide brief intervention to problem drinkers on general medical wards after the introduction of a simple protocol. Regular training in the use of this protocol was stipulated in the annual service contract between the Health Authority and the Hospital Trusts. Improvements in staff practice persisted at 1-year follow-up, although it fell from a peak at an earlier phase of the study. The positive role of state purchasers of health services in sustaining improvements in clinical practice is discussed. (+info)
Urban-rural comparisons of drink-driving behaviour among late teens: a preliminary investigation.
(63/50730)
A preliminary study was conducted to examine the nature and extent of urban-rural differences in self-reported drinking and driving among youths in Western Australia. A total of 102 youths aged 17, 18 and 19 years were surveyed via a random street sampling technique about their alcohol consumption and drink-driving behaviour. Analyses indicated that urban youths had a significantly higher level of self-reported drink-driving behaviour than their rural counterparts. Males indicated a higher level of self-reported drink-driving behaviour than females. This article also provides a review and summary of youth drink-driving literature with special focus on urban-rural comparisons. (+info)
Alcohol consumption, alcohol-related problems, problem drinking, and socioeconomic status.
(64/50730)
In general, a lower socioeconomic status (SES) is related to a lower health status, more health problems, and a shorter life expectancy. Although causal relations between SES and health are unclear, lifestyle factors play an intermediate role. The purpose of the present study was to obtain more insight into the relation between SES, alcohol consumption, alcohol-related problems, and problem drinking, through a general population survey among 8000 people in Rotterdam. Odds ratios were calculated using educational level as independent, and alcohol consumption, alcohol-related problems, and problem drinking as dependent variables. Abstinence decreased significantly by increasing educational level for both sexes. For men, excessive drinking, and notably very excessive drinking, was more prevalent in the lowest educational group. For women, no significant relation between educational level and prevalence of excessive drinking was found. After controlling for differences in drinking behaviour, among men the prevalence of 'psychological dependence' and 'social problems' was higher in intermediate educational groups, whereas prevalence of 'drunkenness' was lower in intermediate educational groups. For women, a negative relation was found between educational level and 'psychological dependence'; prevalence of 'symptomatic drinking' was higher in the lowest educational group. Prevalence of problem drinking was not related to educational level in either sex. It is concluded that differences exist between educational levels with respect to abstinence, but only limited differences were found with respect to excessive drinking. Furthermore, there is evidence for higher prevalences of alcohol-related problems in lower educational levels, after controlling for differences in drinking behaviour, in both sexes. (+info)
