Randomised controlled trial of intensive multifactorial treatment for cardiovascular risk in patients with screen-detected type 2 diabetes: 1-year data from the ADDITION Netherlands study

No negative effects of a multi-factorial, intensified treatment on self-reported health status, treatment satisfaction, and diabetes-related distress in screen-detected type 2 diabetes patients. The ADDITION-Netherlands study

Purpose

To examine the effects of a multi-factorial, intensified treatment on self-reported health status, treatment satisfaction, and diabetes-related distress in screen-detected type 2 diabetes patients.

Methods

Cluster-randomised controlled trial; A total of 498 screen-detected type 2 diabetes patients from 79 general practices were assigned to intensified (n = 255) or routine treatment according to Dutch guidelines (n = 243). At baseline and after 3 years, patients completed the Short Form-36 and the European Quality of Life-5 Dimensions questionnaires. After 4.5 years, patients completed the Diabetes Treatment Satisfaction Questionnaire and the Problem Areas In Diabetes scale. We analysed the effects of intensified treatment on self-rated health status, treatment satisfaction, and diabetes-related distress, using random effects models to account for clustering at practice level.

Results

Three to 5 years after type 2 diabetes was detected by screening, there were no differences between intensified and routine treatment in self-reported health status, treatment satisfaction, and diabetes-related distress.

Conclusions

Multi-factorial, intensified treatment did not influence self-rated health status, treatment satisfaction, and distress in screen-detected type 2 diabetes patients. Therefore, health care professionals do not have to fear negative effects of an intensified treatment on these psychological outcomes.

International Diabetes Federation: An update of the evidence concerning the prevention of type 2 diabetes

This article aims to provide an updated summary of diabetes prevention efforts by reviewing relevant literature published between 2007 and 2009. These include results from the long-term follow-up of diabetes prevention trials and the roll-out of community-based interventions in "real world" settings. Some countries have begun to implement population-based strategies for chronic disease prevention, but investment in developing and evaluating population-level interventions remains inadequate. By focussing on the "small change" approach and involving a number of different agencies, it may be possible to shift the population distribution of risk factors for diabetes and cardiovascular disease in a favourable direction. The cost-effectiveness of primary prevention strategies for type 2 diabetes has not been universally demonstrated. Some of the uncertainties relating to screening for diabetes have now been resolved but longer-term data on hard cardiovascular outcomes are still needed. In summary, individual countries should aim to develop and evaluate cost-effective, setting-specific diabetes risk identification and prevention strategies based on available resources. These should be linked to initiatives aimed at reducing the burden of cardiovascular disease, and complemented with population-based strategies focusing on the control and reduction of behavioural and cardiovascular risk factors by targeting their key determinants.

Multifactorial intervention to reduce cardiovascular events in type 2 diabetes

Type 2 diabetes is associated with a significantly increased risk of cardiovascular disease (CVD) morbidity and mortality. Although several clinical trials have evaluated the effects of interventions to reduce CVD risk in people with diabetes, such studies are primarily conducted to target individual risk factors such as hypertension, hyperglycemia, and dyslipidemia rather than using a multifactorial interventional approach. Existing clinical trial data suggest that intensive multifactorial interventions that target several important risk factors simultaneously result in a significantly greater risk reduction in CVD risk compared with single risk factor interventions. However, few studies have evaluated the efficacy and effectiveness of such interventions on CVD hard end points. A multidisciplinary team management of diabetes should focus on weight control, diet, physical activity, diabetes education, and adherence to pharmacotherapy. An individually tailored aggressive management program to reduce multiple CVD risk factors simultaneously has great potential to prevent CVD morbidity and mortality among patients with type 2 diabetes.
