The Safe Dates program: 1-year follow-up results. (49/1358)

OBJECTIVES: An earlier report described desirable 1-month follow-up effects of the Safe Dates program on psychological, physical, and sexual dating violence. Mediators of the program-behavior relationship also were identified. The present report describes the 1-year follow-up effects of the Safe Dates program. METHODS: Fourteen schools were in the randomized experiment. Data were gathered by questionnaires in schools before program activities and 1 year after the program ended. RESULTS: The short-term behavioral effects had disappeared at 1 year, but effects on mediating variables such as dating violence norms, conflict management skills, and awareness of community services for dating violence were maintained. CONCLUSIONS: The findings are considered in the context of why program effects might have decayed and the possible role of boosters for effect maintenance.  (+info)

Evaluation of a new care system provided to diabetic patients in the outpatient clinic. (50/1358)

OBJECTIVE: Evaluation of metabolic states and chronic complications is essential for maintaining a high quality of care for diabetic patients. We have assessed the quality of care in routine outpatient clinics for diabetic subjects in our university hospital, and compared with those in a newly introduced standardized clinic to evaluate the new care system. METHODS: The quality of care was assessed by the chart review in 1995, and compared with those from 1996-1997 in the "Diabetes Follow-up Clinic" which is systematically designed for the standardized care. PATIENTS: The subjects were recruited among 860 patients who visited the outpatient clinic in July and August of 1995 with a diagnosis of diabetes or glucose intolerance. Six hundred seventy-two patients whose follow-up period had been more than 6 months with clinically diagnosed diabetes were used for the analysis. RESULTS: Laboratory tests such as determination of HbA1c, and serum levels of lipids and creatinine were performed in more than 90% of the patients in the routine outpatient clinics. However, ophthalmology referral, 24-hour urine collection for the determination of creatinine clearance and albumin excretion, and electrocardiograms were not well performed and were incompletely documented (40-60% of the patients within a previous year and 70-80% in the last 2 years). In the standardized "Diabetes Follow-up Clinic", only four out of 555 diabetic patients failed to collect their 24-hour urine, and all participants had ankle blood pressure measurements, nerve conduction study, and nylon monofilament tests, etc. Furthermore, more than 95% of the patients had funduscopic examinations by ophthalmologists as well as records of electrocardiogram. CONCLUSION: Introduction of the standardized "Diabetes Follow-up Clinic" may be one of the choices for increasing the quality of outpatient care and for the prevention of chronic diabetic complications.  (+info)

Community Mothers Programme--seven year follow-up of a randomized controlled trial of non-professional intervention in parenting. (51/1358)

BACKGROUND: The Community Mothers Programme aims at using experienced volunteer mothers in disadvantaged areas to give support to first-time parents in rearing their children up to 1 year of age. The programme was evaluated by randomized controlled trial in 1990. METHODS: Seven years later, trial participants were interviewed about child health, nutrition, cognitive stimulation, parenting skills, and maternal self-esteem. The aim of this study was to see whether the demonstrated benefits at 1 year of age of this programme could be sustained at age 8. RESULTS: One-third of the original group (38 intervention, 38 control), were contacted and interviewed. The risk for having an accident requiring a hospital visit was lower in the intervention group: relative risk (RR) 0.59, 95 per cent confidence interval (CI) 0.31-1.11. Intervention children were more likely to visit the library weekly: RR 1.58, 95 per cent CI 1.10-2.26. Intervention mothers were more likely to check homework every night: RR 1.23, 95 per cent CI 1.05-1.43 (p=0.006); and to disagree with the statement 'children should be smacked for persistently bad behaviour': RR 2.11, 95 per cent CI 1.10-4.06. They were more likely to disagree with the statement 'I do not have much to be proud of': RR 1.24, 95 per cent CI 1.04-1.40; and to make a positive statement about motherhood than controls: RR 1.53, 95 per cent CI 1.06-2.20. Subsequent children of intervention mothers were more likely to have completed Haemophilus influenzae b: RR 1.26, 95 per cent CI 1.06-1.51; and polio immunization: RR 1.19, 95 per cent CI 1.02-1.40. CONCLUSIONS: The Community Mothers programme had sustained beneficial effects on parenting skills and maternal self-esteem 7 years later with benefit extending to subsequent children.  (+info)

The effect of capitated financing on mental health services for children and youth: the Colorado experience. (52/1358)

OBJECTIVES: This study tested 2 propositions concerning the effect of capitated financing on mental health services for Medicaid-eligible children and youth in Colorado. The first is that capitation reduces costs. The second is that shifting providers from fee-for-service to capitated financing will increase their efforts to prevent illness. METHODS: Interrupted time-series designs were applied to a naturally occurring quasi experiment occasioned by the state of Colorado's reorganization of mental health services financing. RESULTS: The cost of services was significantly lower in counties with capitated services compared with counties with fee-for-service financing. Findings also suggested that economic incentives may lead to greater efforts at secondary and tertiary prevention. CONCLUSIONS: Policymakers and the public can expect that capitation will reduce the costs of children's mental health services below those likely with fee-for-service financing. Capitation per se, however, may not increase prevention as surely or swiftly as it lowers costs.  (+info)

Prevention and early detection of malignant melanoma. (53/1358)

In addressing the problem of malignant melanoma, family physicians should emphasize primary prevention. This includes educating patients about the importance of avoiding excessive sun exposure and preventing sunburns, and advising them about the importance of prompt self-referral for changing nevi. Family physicians should be able to perform an overall risk assessment for melanoma, particularly to identify persons with familial atypical mole syndrome. Patients with such high risk should be strongly considered for referral for dermatologic surveillance. Because there are no systematic studies in primary care populations, there are no data on which to base recommendations for periodic screening in this setting. However, when performing any part of the physical examination, family physicians should be alert for suspicious nevi. Nevi detected by the family physician or pointed out by the patient should be subject to excisional biopsy with accepted techniques or be referred for such a procedure.  (+info)

Application of a generalized random effects regression model for cluster-correlated longitudinal data to a school-based smoking prevention trial. (54/1358)

In cluster-randomized trials, groups of subjects (clusters) are assigned to treatments, whereas observations are taken on the individual subjects. Since observations on subjects in the same cluster are typically more similar than observations from different clusters, analyses of such data must take intracluster correlation into account rather than assuming independence among all observations. Random effects models are useful for this purpose. The problem becomes more complicated if, in addition, repeated observations are taken on subjects over time. This introduces intraindividual correlation, which is typical for longitudinal studies. The Waterloo Smoking Prevention Project, study 3 (WSPP3), 1989-1996, is a study giving rise to cluster-correlated longitudinal data, where schools were randomized to either a smoking intervention program or to a control condition. Smoking status was assessed on grade 6 students in these schools, with annual follow-up observations throughout elementary and high school years. The authors illustrate the use of a generalized random effects model for analyzing this type of data. This model obtains appropriate estimates and standard errors for both individual-level covariates and those at the level of the cluster.  (+info)

Aspirin for primary prevention of coronary heart disease: safety and absolute benefit related to coronary risk derived from meta-analysis of randomised trials. (55/1358)

OBJECTIVE: To determine the cardiovascular and coronary risk thresholds at which aspirin for primary prevention of coronary heart disease is safe and worthwhile. DESIGN: Meta-analysis of four randomised controlled trials of aspirin for primary prevention. The benefit and harm from aspirin treatment were examined to determine: (1) the cardiovascular and coronary risk threshold at which benefit in prevention of myocardial infarction exceeds harm from significant bleeding; and (2) the absolute benefit expressed as number needed to treat (NNT) for aspirin net of cerebral haemorrhage and other bleeding complications at different levels of coronary risk. MAIN OUTCOME MEASURES: Benefit from aspirin, expressed as reduction in cardiovascular events, myocardial infarctions, strokes, and total mortality; harm caused by aspirin in relation to significant bleeds and major haemorrhages. RESULTS: Aspirin for primary prevention significantly reduced all cardiovascular events by 15% (95% confidence interval (CI) 6% to 22%) and myocardial infarctions by 30% (95% CI 21% to 38%), and non-significantly reduced all deaths by 6% (95% CI -4% to 15%). Aspirin non-significantly increased strokes by 6% (95% CI -24% to 9%) and significantly increased bleeding complications by 69% (95% CI 38% to 107%). The risk of major bleeding balanced the reduction in cardiovascular events when cardiovascular event risk was 0.22%/year. The upper 95% CI for this estimate suggests that harm from aspirin is unlikely to outweigh benefit provided the cardiovascular event risk is 0.8%/year, equivalent to a coronary risk of 0.6%/year. At coronary event risk 1.5%/year, the five year NNT was 44 to prevent a myocardial infarction, and 77 to prevent a myocardial infarction net of any important bleeding complication. At coronary event risk 1%/year the NNT was 67 to prevent a myocardial infarction, and 182 to prevent a myocardial infarction net of important bleeding. CONCLUSIONS: Aspirin treatment for primary prevention is safe and worthwhile at coronary event risk >/= 1.5%/year; safe but of limited value at coronary risk 1%/year; and unsafe at coronary event risk 0.5%/year. Advice on aspirin for primary prevention requires formal accurate estimation of absolute coronary event risk.  (+info)

Latest approaches to preventing alcohol abuse and alcoholism. (56/1358)

Scientists and policymakers have explored numerous strategies to prevent alcohol abuse and dependence as well as the adverse social, legal, and medical consequences of alcohol use. Many of these efforts have focused on reducing alcohol-impaired driving and the associated injuries and fatalities. As reported in this article, such efforts have included general deterrence laws (e.g., reduced minimum legal drinking age, administrative license revocation, and lower legal limits for blood alcohol concentrations), measures targeted at repeat offenders, and measures to control alcohol availability (e.g., increased taxes and decreased numbers of establishments selling alcohol).  (+info)
