Effect of multiple patient reminders in improving diabetic retinopathy screening. A randomized trial.
(49/7064)
OBJECTIVE: To determine whether multiple mailed patient reminders can produce an increase in the rate of diabetic retinal examinations (DRE) over that seen with a single reminder. RESEARCH DESIGN AND METHODS: All diabetic members > or = 18 years who were enrolled in a large network-based health maintenance organization (HMO) in California from August 1996 to July 1997 were identified using claims and pharmacy databases. Members who had no record of DRE in the HMO's claims database were then randomized into two groups. Both groups received mailed educational materials and a reminder to obtain the examination. Their physician groups also received a letter explaining the program, current guidelines for DRE, and a list of their diabetes patients with their DRE status. The single intervention group received no additional reminders. The multiple intervention group received additional reminders at 3, 6, and 9 months after baseline if they continued with no record of service, as determined from the claims database. RESULTS: The study cohort comprised 19,523 diabetic members, which were randomized into single (n = 9,614) and multiple (n = 9,909) intervention groups. There was an increase in monthly DRE rates after the intervention in August 1996 for both intervention groups. After the second reminder was sent to the multiple intervention group, the percentage of diabetic members receiving DRE was higher than the single intervention group. Rates before and after the third intervention were not significantly different, nor were monthly differences found. There was a significant difference in overall annual DRE rates between the groups (P = 0.023). CONCLUSIONS: Multiple patient reminders are more effective than single reminders in improving DRE rates in a managed care setting. However, the improvement noted was clinically small and appeared only after the second reminder; no incremental improvement was seen with additional reminders. Resources used for multiple reminders aimed at diabetic retinopathy might better be spent on other approaches to reducing complications of diabetes. (+info)
Racial bias in federal nutrition policy, Part II: Weak guidelines take a disproportionate toll.
(50/7064)
Many diet-related chronic diseases take a disproportionate toll among members of racial minorities. Research shows the prevalence of diabetes, hypertension, cancer, and heart disease is higher among various ethnic groups compared with whites. The Guidelines and the Food Guide Pyramid, however, promote the use of multiple servings of meats and dairy products each day and do not encourage replacing these foods with vegetables, legumes, fruits, and grains. The Dietary Guidelines for Americans encourage a 30% caloric reduction in fat intake and make no provision for further reductions for those who wish to minimize health risks. Abundant evidence has shown that regular exercise combined with diets lower in fat and richer in plant products than is encouraged by the Dietary Guidelines for Americans are associated with reduced risk of these chronic conditions. While ineffective Dietary Guidelines potentially put all Americans at unnecessary risk, this is particularly true for those groups hardest hit by chronic disease. (+info)
Health consciousness of young people in relation to their personality.
(51/7064)
Personality of targeted individuals can be assumed to influence behavior modification by health education. In this study the influence of personality on health consciousness was analyzed by a questionnaire for lifestyle, health consciousness, and the NEO-FFI personality test. Subjects were 942 new students in the Tokyo University of Agriculture who were surveyed in April, 1998. Separately performed health examination data were used to verify reliability of answers to the questionnaire. Among students, 83.2% of males and 90.4% of females felt themselves to be healthy, and more than 80% students desired to improve their health more. The rate of having no physical complaints, however, was only 31.7% in males and 20.4% in females. Distribution of NEO-FFI scores of neuroticism (N), extraversion (E), openness (O), agreeableness (A), and conscientiousness (C) corresponded well between males and females, except for significantly higher scores of O and A in females. Odds ratios (ORs) between high and low tertial points of NEO-FFI score for health consciousness were significantly elevated in the high scoring groups of E and C (OR = 6.26, 95% CI = 1.46-26.82, and OR = 6.04, 95% CI = 1.42-25.71, respectively) in males. On the contrary, high N and O groups had low health consciousness. Smoking habit was associated with high E scores (OR = 2.24, 95% CI = 1.13-4.43). Dietary habits, regular eating time, and avoidance of salty foods were associated with high C scores in both males and females. The OR of regular eating time was 2.66 (95% CI = 1.42-1.98), and 2.20 (95% CI = 1.31-3.71) for males and females, respectively. The OR of avoidance of salty foods were 2.09 (95% CI = 1.11-3.91), 1.87 (95% CI = 1.11-3.16) for males and females, respectively. Significant associations between lifestyle and personality require further study for risk association analysis and for relationship to interventive practices for prevention of lifestyle associated diseases.

Our Healthier Nation: are general practitioners willing and able to deliver? A survey of attitudes to and involvement in health promotion and lifestyle counselling.
(52/7064)
BACKGROUND: The recent Green Paper, Our Healthier Nation, identifies professional advice on healthier living as a key component of its national contract for health. General practitioners (GPs) are ideally placed for this work. However, previous research has reported a discrepancy between patients' expectations of lifestyle advice from GPs and their receipt of such advice. AIMS: To describe GPs' current attitudes to and involvement in health promotion and lifestyle counselling, and to track changes in these areas over recent years. METHOD: A postal questionnaire survey of a random sample of 430 GPs, one per practice, from all general practices in Leicestershire, Derbyshire, and Nottinghamshire. GPs who had not responded after two weeks received a reminder telephone call plus two follow-up questionnaires. RESULTS: Four hundred and eleven GPs were eligible for the survey, which yielded a response rate of 68% (n = 279). GPs reported spending an average 16% of practice time on prevention and 79% reported educating patients about lifestyle risk 'most' or 'all of the time'. Solo GPs spent more time on prevention than GPs from group practices. Most enquiries and interventions related to smoking behaviour. GPs felt most effective in changing patients' use of prescription drugs, and the largest reported difference between current and potential effectiveness in helping patient change lifestyle behaviour, after information and training, related to reducing alcohol consumption. CONCLUSIONS: Despite an increasing workload, GPs remain positive about health promotion and lifestyle counselling. Over the past 10 years, there has been an increase in routine enquiries about lifestyle behaviour, but confidence about effectiveness in helping patients changes lifestyle behaviour remains low. More training and support concerning lifestyle intervention is required by GPs in order for them to contribute effectively to the Government's health promotion programme. (+info)
Assessing public health capacity to support community-based heart health promotion: the Canadian Heart Health Initiative, Ontario Project (CHHIOP).
(53/7064)
This paper presents initial findings of the Canadian Heart Health Initiative, Ontario Project (CHHIOP). CHHIOP has two primary objectives. The programmatic objective is to coordinate and refine a system for supporting effective, sustained community-based heart health activities. This paper addresses the scientific objective: to develop knowledge of factors that influence the development of predisposition and capacity to undertake community-based heart health activities in public health departments. A systems theory framework for an ecological approach to health promotion informs the conceptualization of the key constructs, measured using a two-stage longitudinal design which combines quantitative and qualitative methods. This paper reports the results of the first round of quantitative survey data collected from all health departments in Ontario (N = 42) and individuals within each health department involved in heart health promotion (n = 262). Results indicate low levels of implementation of heart health activities, both overall and for particular risk factors and settings. Levels of capacity are also generally low, yet predisposition to undertake heart health promotion activities is reportedly high. Analyses show that implementation is positively related to capacity but not predisposition, while predisposition and capacity are positively related. Overall, results suggest predisposition is a necessary but not sufficient condition for implementation to occur; capacity-related factors appear to be the primary constraint. These findings are used to inform strategies to address CHHIOP's programmatic objective. (+info)
Community-based interventions to improve breast and cervical cancer screening: results of the Forsyth County Cancer Screening (FoCaS) Project.
(54/7064)
The FoCaS (Forsyth County Cancer Screening) Project was one of six projects funded by the National Cancer Institute "Public Health Approaches to Breast and Cervical Cancer" initiative. The goal of this project was to improve the use of breast and cervical cancer screening among low-income, predominately African-American, women age 40 and older. Strategies implemented in the intervention city included public health clinic in-reach strategies (chart reminders, exam room prompts, in-service meetings, and patient-directed literature) and community outreach strategies (educational sessions, literature distribution, community events, media, and church programs). Baseline and follow-up data from independent cross-sectional samples in both the intervention and comparison cities were used to evaluate the effects of the intervention program. A total of 248 women were surveyed at baseline, and 302 women were surveyed 3 years later at follow-up. The proportion of women reporting regular use of mammography increased (31 to 56%; P < 0.001) in the intervention city. In the comparison city, a nonsignificant (ns) increase in mammography utilization was observed (33 to 40%; P = ns). Pap smear screening rates also improved in the intervention city (73 to 87%; P = 0.003) but declined in the comparison city (67 to 60%; P = ns). These relationships hold in multivariate models. The results suggest that a multifaceted intervention can improve screening rates in low-income populations. These results have important implications for community-based research and efforts in underserved populations. (+info)
Child health promotion in developing countries: the case for integration of environmental and social interventions?
(55/7064)
In spite of improving epidemiological knowledge in relation to child health, the challenge of promoting the survival and quality of life of infants and children in most parts of the developing world remains an abiding public health problem, for both the countries and the international agencies involved. Current infant and child health programmes largely reflect western style medical care, with emphasis placed on reducing mortality, and the preventive aspects confined mainly to immunisation, improved nutrition, provision of micronutrients, promotion of breast-feeding and birth spacing. In contrast, environmental and social factors which underpin the proliferation of disease agents are receiving minimal attention. This paper presents a critical review of current strategies for promoting child health in developing countries, and examines the environmental, social, and political factors that influence child health. Presenting a specific example of infant and childhood diarrhoea, the authors argue that in order for a real reduction in mortality, and improvements in quality of life to be sustained, attention needs to be focused equally on the environmental and social factors that underlie much of the childhood diseases in the developing world. This will involve the adoption of a broader strategy aimed at reducing childhood diarrhoea, using the hazard analysis critical control point (HACCP) system in combination with other methods. (+info)
Changing physician practice of physical activity counseling.
(56/7064)
We conducted a prospective controlled trial to determine whether an educational intervention could improve resident physician self-efficacy and counseling behaviors for physical activity and increase their patients' reported activity levels. Forty-eight internal medicine residents who practiced at a Department of Veterans Affairs hospital received either two workshops on physical activity counseling or no intervention. All residents completed questionnaires before and 3 months after the workshops. The 21 intervention physicians reported increased self-efficacy for counseling and increased frequency of counseling compared with the 27 control physicians. Approximately 10 patients of each resident were included in the study and surveyed before and 6 months after the intervention. Of 560 patients, 465 (83%) returned both questionnaires. Following the intervention, there were no significant differences between patients of intervention and control physicians on any outcome measures. We conclude that educational interventions can improve physicians' reported self-efficacy of physical activity counseling but may not increase patient physical activity levels. Alternative approaches that emphasize overcoming the substantial barriers to exercise in chronically ill outpatients clearly will be important for facilitating changes in physical activity. (+info)
