Group based training for self-management strategies in people with type 2 diabetes mellitus

Improving health outcomes with better patient understanding and education

A central plank of health care reform is an expanded role for educated consumers interacting with responsive health care teams. However, for individuals to realize the benefits of health education also requires a high level of engagement. Population studies have documented a gap between expectations and the actual performance of behaviours related to participation in health care and prevention. Interventions to improve self-care have shown improvements in self-efficacy, patient satisfaction, coping skills, and perceptions of social support. Significant clinical benefits have been seen from trials of self-management or lifestyle interventions across conditions such as diabetes, coronary heart disease, heart failure and rheumatoid arthritis. However, the focus of many studies has been on short-term outcomes rather that long term effects. There is also some evidence that participation in patient education programs is not spread evenly across socio economic groups. This review considers three other issues that may be important in increasing the public health impact of patient education. The first is health literacy, which is the capacity to seek, understand and act on health information. Although health literacy involves an individual's competencies, the health system has a primary responsibility in setting the parameters of the health interaction and the style, content and mode of information. Secondly, much patient education work has focused on factors such as attitudes and beliefs. That small changes in physical environments can have large effects on behavior and can be utilized in self-management and chronic disease research. Choice architecture involves reconfiguring the context or physical environment in a way that makes it more likely that people will choose certain behaviours. Thirdly, better means of evaluating the impact of programs on public health is needed. The Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework has been promoted as one such potential approach.

The global challenge of type 2 diabetes and the strategies for response in ethnic minority groups

Ethnic minorities living in high-income countries usually exhibit a greater risk of developing diabetes along with higher morbidity and mortality rates. We evaluated the effectiveness of interventions to improve glycaemic control in ethnic minority groups. Results of major controlled trials, systematic reviews and meta-analyses were included in the review. Only 1/47 studies addressing diet and exercise interventions reported details on the ethnicity of the studied population. Self-management education was successful if associated with increased self-efficacy; delivered over a longer period; of high intensity; culturally tailored; and when using community educators. Strategies adopted in community-gathering places, family-based, multifaceted, and those tackling the social context were likely to be more effective. A positive relationship was found between social support and self-management behaviour as well as quality of life, but there is little evidence about the impact of organizational changes within health-care services on diabetes control. More research is needed to strengthen the evidence on effective strategies for response to diabetes in ethnic minorities. Also, there is a need to take into account diabetes beliefs and communication difficulties, as well as potential protective factors. Globally, many health-care systems are inadequately equipped to improve diabetes prevention and disease outcomes in these communities.

Designing and remotely testing mobile diabetes video games

We have investigated game design and usability for three mobile phone video games designed to deliver diabetes education. The games were refined using focus groups. Six people with diabetes participated in the first focus group and five in the second. Following the focus groups, we incorporated the new findings into the game design, and then conducted a field test to evaluate the games in the context in which they would actually be used. Data were collected remotely about game usage by eight people with diabetes. The testers averaged 45 seconds per question and answered an average of 50 total nutrition questions each. They self-reported playing the game for 10-30 min, which coincided with the measured metrics of the game. Mobile games may represent a promising new way to engage the user and deliver relevant educational content.

Long-term impact of a structured group-based inpatient-education program for intensive insulin therapy in patients with diabetes mellitus

PURPOSE

Structured patient education aiming to improve self-management strategies might be beneficial for insulin-treated diabetic patients. However, in previous studies the extent of the benefit has been inconsistent in different subgroups of patients. The aim of the present study was to assess the potential benefit of a structured inpatient-education program for intensive insulin therapy according to the basal-bolus concept with particular emphasis on self-management strategies.

METHODS

We included 81 diabetic patients (59 with type 1, 14 with type 2, eight with other forms) in this retrospective longitudinal study; all had completed the training program on eight consecutive days at a university clinic between 2003 and 2005. Data assessment included HbA1c, LDL-cholesterol, HDL-cholesterol and BMI at baseline (0-15 months before the training) and after 0-5, 5-10 and 10-20 months.

RESULTS

A transient decrease of HbA1c (0.2%, 95% CI: 0.04-0.37, P = 0.017) and LDL-cholesterol levels (9.95 mg/dl, 95% CI: 2.24-17.76, P = 0.013) between baseline and the first follow-up examination was observed in the group overall. Thereafter, HbA1c and LDL-cholesterol were similar to baseline, whereas a persistent increase in HDL-cholesterol (P = 0.025) was evident in the multivariable analysis. No changes in BMI were observed. A significant type-by-time interaction (P = 0.008) in HbA1c suggests a long-term benefit in glycemic control in patients with type 2 diabetes.

CONCLUSION

A diabetes training program for intensive insulin therapy with particular emphasis on self-management skills was followed by a moderate and transient improvement of glycemic control and LDL-cholesterol and by a persistent increase in HDL-cholesterol. Long-term improvement in glycemic control was observed only in patients with type 2 diabetes.

Online diabetes self-management program: a randomized study

OBJECTIVE

We hypothesized that people with type 2 diabetes in an online diabetes self-management program, compared with usual-care control subjects, would 1) demonstrate reduced A1C at 6 and 18 months, 2) have fewer symptoms, 3) demonstrate increased exercise, and 4) have improved self-efficacy and patient activation. In addition, participants randomized to listserve reinforcement would have better 18-month outcomes than participants receiving no reinforcement.

RESEARCH DESIGN AND METHODS

A total of 761 participants were randomized to 1) the program, 2) the program with e-mail reinforcement, or 3) were usual-care control subjects (no treatment). This sample included 110 American Indians/Alaska Natives (AI/ANs). Analyses of covariance models were used at the 6- and 18-month follow-up to compare groups.

RESULTS

At 6 months, A1C, patient activation, and self-efficacy were improved for program participants compared with usual care control subjects (P < 0.05). There were no changes in other health or behavioral indicators. The AI/AN program participants demonstrated improvements in health distress and activity limitation compared with usual-care control subjects. The subgroup with initial A1C >7% demonstrated stronger improvement in A1C (P = 0.01). At 18 months, self-efficacy and patient activation were improved for program participants. A1C was not measured. Reinforcement showed no improvement.

CONCLUSIONS

An online diabetes self-management program is acceptable for people with type 2 diabetes. Although the results were mixed they suggest 1) that the program may have beneficial effects in reducing A1C, 2) AI/AN populations can be engaged in and benefit from online interventions, and 3) our follow-up reinforcement appeared to have no value.

Peer-based behavioural strategies to improve chronic disease self-management and clinical outcomes: evidence, logistics, evaluation considerations and needs for future research

The diagnosis of a chronic disease such as diabetes generally evokes strong emotions and often brings with it the need to make changes in lifestyle behaviours, such as diet, exercise, medication management and monitoring clinical and metabolic parameters. The diagnosis thus affects not only the person diagnosed but also the family members. Chronic illnesses are largely self-managed with approximately 99% of the care becoming the responsibility of patients and their families or others involved in the daily management of their illnesses. While the responsibility for outcomes, such as metabolic control and chronic complications, are shared with the health care team, the daily decisions and behaviours adopted by patients clearly have a strong influence on their future health and well-being. While diabetes self-management education is essential, it is generally not sufficient for patients to sustain behaviours and cope with a lifetime of diabetes. Peers have been proposed as one method for assisting patients to deal with the behavioural and affective components of diabetes and to provide ongoing self-management support. This paper first describes effective behavioural strategies in diabetes, based on multiple studies and/or meta-analyses, and then provides examples of their use by peers or in peer-based programmes in diabetes. A comprehensive search using the MEDLINE and Cinahl databases was conducted. Key search terms included peer mentors, peer leaders, peer educators, lay health workers and community health workers. Studies that clearly identified behavioural strategies used by peers were included.

Culturally appropriate health education for Type 2 diabetes in ethnic minority groups: a systematic and narrative review of randomized controlled trials

To determine if culturally appropriate health education is more effective than 'usual' health education for people with diabetes from ethnic minority groups living in high- and upper-middle-income countries. A systematic review with meta-analysis, following the methodology of the Cochrane Collaboration. Electronic literature searches of nine databases were made, with hand searching of three journals and 16 author contacts. The criteria for inclusion into the analysis were randomized controlled trials of a specified diabetes health education intervention, and a named ethnic minority group with Type 2 diabetes. Data were collected on HbA(1c), blood pressure, and quality-of-life measures. A narrative review was also performed. Few studies fitted the selection criteria, and were heterogeneous in methodologies and outcome measures, making meta-analysis difficult. HbA(1c) showed an improvement at 3 months [weighted mean difference (WMD) -0.32%, 95% confidence interval (CI) -0.63, -0.01] and 6 months post intervention (WMD -0.60%, 95% CI -0.85, -0.35). Knowledge scores also improved in the intervention groups at 6 months (standardized mean difference 0.46, 95% CI 0.27, 0.65). There was only one longer-term follow-up study, and one formal cost-effectiveness analysis. Culturally appropriate health education was more effective than 'usual' health education in improving HbA(1c) and knowledge in the short to medium term. Due to poor standardization between studies, the data did not allow determination of the key elements of interventions across countries, ethnic groups and health systems, or a broad view of their cost-effectiveness. The narrative review identifies learning points to direct future research.

Lifting the lid of the "black intervention box" - the systematic development of an action competence programme for people with screen-detected dysglycaemia

Background

The evidence gained from effective self-management interventions is often criticised for the ambiguity of its active components, and consequently the obstruction of their implementation into daily practice.

Our aim is to report how an intervention development model aids the careful selection of active components in an intervention for people with dysglycaemia.

Methods

The first three phases of the UK Medical Research Council's model for developing complex interventions in primary care were used to develop a self-management intervention targeting people with screen-detected dysglycaemia. In the preclinical phase, the expected needs of the target group were assessed by review of empirical literature and theories. In phase I, a preliminary intervention was modelled and in phase II, the preliminary intervention was pilot tested.

Results

In the preclinical phase the achievement of health-related action competence was defined as the overall intervention goal and four learning objectives were identified: motivation, informed decision-making, action experience and social involvement. In Phase I, the educational activities were defined and the pedagogical tools tested. In phase II, the intervention was tested in two different primary healthcare settings and adjusted accordingly. The 18-hour intervention "Ready to Act" ran for 3 months and consisted of two motivational one-to-one sessions conducted by nurses and eight group meetings conducted by multidisciplinary teams.

Conclusions

An intervention aimed at health-related action competence was successfully developed for people with screen-detected dysglycaemia. The systematic and transparent developmental process is expected to facilitate future clinical research. The MRC model provides the necessary steps to inform intervention development but should be prioritised according to existing evidence in order to save time.

Rethink Organization to iMprove Education and Outcomes (ROMEO): a multicenter randomized trial of lifestyle intervention by group care to manage type 2 diabetes

OBJECTIVE

A trial was performed to establish whether our group care model for lifestyle intervention in type 2 diabetes can be exported to other clinics.

RESEARCH DESIGN AND METHODS

This study was a 4-year, two-armed, multicenter controlled trial in 13 hospital-based diabetes clinics in Italy (current controlled trials no. ISRCTN19509463). A total of 815 non-insulin-treated patients aged <80 years with > or =1 year known diabetes duration were randomized to either group or individual care.

RESULTS

After 4 years, patients in group care had lower A1C, total cholesterol, LDL cholesterol, triglycerides, systolic and diastolic blood pressure, BMI, and serum creatinine and higher HDL cholesterol (P < 0.001, for all) than control subjects receiving individual care, despite similar pharmacological prescriptions. Health behaviors, quality of life, and knowledge of diabetes had become better in group care patients than in control subjects (P < 0.001, for all).

CONCLUSIONS

The favorable clinical, cognitive, and psychological outcomes of group care can be reproduced in different clinical settings.

Seeking the views of health professionals on translating chronic disease self-management models into practice

Few studies have investigated the views of health professionals with respect to their use of chronic disease self-management (CDSM) in the workplace.

OBJECTIVE

This qualitative study, conducted in an Australian health care setting, examined health professional's formal self-management (SM) training and their views and experiences on the use of SM techniques when working with people living with a chronic illness.

METHODS

Purposive sample of 31 health care professionals from a range of service types participated in semi-structured interviews.

RESULTS

The majority of participants (65%) had received no formal training in SM techniques. Participants reported a preference for an eclectic approach to SM, relying primarily on five elements: collaborative care, self-responsibility, client's individual situation, structured support and linking with community agencies. Problems with CDSM centred on medication management, complex measuring devices and limited efficacy with some patient groups.

CONCLUSION

This study provides valuable information with respect to the use of CDSM within the workplace from the unique perspective of a range of healthcare providers within an Australian health care setting.

PRACTICE IMPLICATIONS

Training implications, with respect to CDSM and patient care, are discussed, together with how these findings contribute to the debate concerning how SM principles are translated into healthcare settings.

There were no changes in other health or behavioral indicators. The AI/AN program participants demonstrated improvements in health distress and activity limitation compared with usual-care control subjects. The subgroup with initial A1C >7% demonstrated stronger improvement in A1C (P = 0.01). At 18 months, self-efficacy and patient activation were improved for program participants. A1C was not measured. Reinforcement showed no improvement.

CONCLUSIONS

An online diabetes self-management program is acceptable for people with type 2 diabetes. Although the results were mixed they suggest 1) that the program may have beneficial effects in reducing A1C, 2) AI/AN populations can be engaged in and benefit from online interventions, and 3) our follow-up reinforcement appeared to have no value.

The disease management program for type 2 diabetes in Germany enhances process quality of diabetes care - a follow-up survey of patient's experiences

Background

In summer 2003 a disease management program (DMP) for type 2 diabetes was introduced on a nationwide basis in Germany. Patient participation and continuity of care within the DMP are important factors to achieve long-term improvements in clinical endpoints. Therefore it is of interest, if patients experience any positive or negative effects of the DMP on their treatment that would support or hamper further participation. The main objective of the study was to find out if the German Disease Management Program (DMP) for type 2 diabetes improves process and outcome quality of medical care for patients in the light of their subjective experiences over a period of one year.

Methods

Cohort study with a baseline interview and a follow-up after 10.4 ± 0.64 months. Data on process and outcome measures were collected by telephone interviews with 444 patients enrolled and 494 patients not enrolled in the German DMP for type 2 diabetes. Data were analyzed by multivariate logistic regression analyses.

Results

DMP enrolment was significantly associated with a higher process quality of care. At baseline enrolled patients more often reported that they had attended a diabetes education course (OR = 3.4), have ≥ 4 contacts/year with the attending physician (OR = 3.3), have at least one annual foot examination (OR = 3.1) and one referral to an ophthalmologist (OR = 3.4) and possess a diabetes passport (OR = 2.4). Except for the annual referral to an ophthalmologist these parameters were also statistically significant at follow-up. In contrast, no differences between enrolled and not enrolled patients were found concerning outcome quality indicators, e.g. self-rated health, Glycated hemoglobin (GHb) and blood pressure. However, 16-36% of the DMP participants reported improvements of body weight and/or GHb and/or blood pressure values due to enrolment - unchanged within one year of follow-up.

Conclusions

In the light of patient's experiences the DMP enhances the process quality of medical care for type 2 diabetes in Germany. The lack of significant differences in outcome quality between enrolled and not enrolled patients might be due to the short program duration. Our data suggest that the DMP for type 2 diabetes should not be withdrawn unless an evidently more promising approach is found.

Integration of healthcare rehabilitation in chronic conditions

Introduction

Quality of care provided to people with chronic conditions does not often fulfil standards of care in Denmark and in other countries. Inadequate organisation of healthcare systems has been identified as one of the most important causes for observed performance inadequacies, and providing integrated healthcare has been identified as an important organisational challenge for healthcare systems. Three entities—Bispebjerg University Hospital, the City of Copenhagen, and the GPs in Copenhagen—collaborated on a quality improvement project focusing on integration and implementation of rehabilitation programmes in four conditions.

Description of care practice

Four multidisciplinary rehabilitation intervention programmes, one for each chronic condition: chronic obstructive pulmonary disease, type 2 diabetes, chronic heart failure, and falls in elderly people were developed and implemented during the project period. The chronic care model was used as a framework for support of implementing and integration of the four rehabilitation programmes.

Conclusion and discussion

The chronic care model provided support for implementing rehabilitation programmes for four chronic conditions in Bispebjerg University Hospital, the City of Copenhagen, and GPs' offices. New management practices were developed, known practices were improved to support integration, and known practices were used for implementation purposes. Several barriers to integrated care were identified.

Patient participation: current knowledge and applicability to patient safety

Patient participation is increasingly recognized as a key component in the redesign of health care processes and is advocated as a means to improve patient safety. The concept has been successfully applied to various areas of patient care, such as decision making and the management of chronic diseases. We review the origins of patient participation, discuss the published evidence on its efficacy, and summarize the factors influencing its implementation. Patient-related factors, such as acceptance of the new patient role, lack of medical knowledge, lack of confidence, comorbidity, and various sociodemographic parameters, all affect willingness to participate in the health care process. Among health care workers, the acceptance and promotion of patient participation are influenced by other issues, including the desire to maintain control, lack of time, personal beliefs, type of illness, and training in patient-caregiver relationships. Social status, specialty, ethnic origin, and the stakes involved also influence patient and health care worker acceptance. The London Declaration, endorsed by the World Health Organization World Alliance for Patient Safety, calls for a greater role for patients to improve the safety of health care worldwide. Patient participation in hand hygiene promotion among staff to prevent health care-associated infection is discussed as an illustrative example. A conceptual model including key factors that influence participation and invite patients to contribute to error prevention is proposed. Further research is essential to establish key determinants for the success of patient participation in reducing medical errors and in improving patient safety.

Patient education in the contemporary management of coronary heart disease

This is the protocol for a review and there is no abstract. The objectives are as follows: To assess the effects of patient education compared with usual care on mortality and morbidity in patients with CHD.To explore the potential study level predictors of the effects of patient education in patients with CHD.

Structured patient education: the X-PERT Programme

The X-PERT Programme seeks to develop the knowledge, skills and confidence in diabetes treatment for health-care professionals and diabetes self-management. The programme trains health-care professionals to deliver the six-week structured patient education programme to people with diabetes. Over 850 health-care professionals have attended the X-PERT 'Train the Trainer' course and audit results document improved job satisfaction and competence in diabetes treatment and management. National audit statistics for X-PERT implementation to people with diabetes illustrate excellent attendance rates, improved diabetes control, reduced weight, blood pressure, cholesterol and waist circumference and more confidence in self-managing diabetes that has impacted positively on quality of life.

Randomized trial of a behavioral weight loss intervention for low-income women: the Weight Wise Program

Low-income women in the United States have the highest rates of obesity, yet they are seldom included in weight loss trials. To address this research gap, components of two evidence-based weight loss interventions were adapted to create a 16-week intervention for low-income women (Weight Wise Program), which was evaluated in a randomized trial with the primary outcome of weight loss at 5-month follow-up. Participants were low-income women (40-64 years) with a BMI of 25-45. Of 143 participants, 72 were randomized to the Weight Wise Program (WWP) and 71 to the Control Group (CG). Five-month follow-up data were obtained from 64 (89%) WWP and 62 (87%) CG participants. With baseline values carried forward for missing data, WWP participants had a weight change of -3.7 kg compared to 0.7 kg in the CG (4.4 kg difference, 95% confidence interval (CI), 3.2-5.5, P<0.001). For systolic blood pressure (SBP), change in the WWP was -6.5 mm Hg compared to -0.4 mm Hg among controls (6.2 mm Hg difference, 95% CI, 1.7-10.6, P=0.007); for diastolic BP (DBP), changes were -4.1 mm Hg for WWP compared to -1.3 mm Hg for controls (2.8 mm Hg difference, 95% CI, 0.0-5.5, P=0.05). Of the 72 WWP participants, 64, 47, and 19% lost at least 3, 5, and 7% of their initial body weight, respectively. In conclusion, the WWP was associated with statistically significant and clinically important short-term weight loss.

Effects of efforts to intensify management on blood pressure control among patients with type 2 diabetes mellitus and hypertension: a pilot study

There continues to be a need for improved medical management of diabetes patients with hypertension in primary care. While several care models have shown effectiveness in achieving various outcomes among these patients, it remains unclear what care model is most effective in improving blood pressure control in primary care. In this prospective study, 54 patients with type 2 diabetes mellitus and blood pressure of >140/90 identified through the registry, were randomized into three groups. Group A attended a nurse educator-conducted class on diabetes and hypertension, group B attended the same class and was asked to monitor their home blood pressure using provided device, and group C served as control (usual care). Of the 24 subjects who completed the study, only 20% achieved the target blood pressure of <130/80 and there was no statistical difference in mean systolic and diastolic blood pressures among the three groups (p > 0.05). Efforts to intensify management of hypertension among type 2 diabetes patients did not result in better blood pressure control compared to usual care. Studies looking into factors which limit patients’ participation in group classes and determining patients’ preferences in disease management would be helpful in ensuring success of any chronic disease management program.

Cost-effectiveness of lifestyle modification in diabetic patients

OBJECTIVE To explore the potential long-term health and economic consequences of lifestyle interventions for diabetic patients. RESEARCH DESIGN AND METHODS A literature search was performed to identify interventions for diabetic patients in which lifestyle issues were addressed. We selected recent (2003-2008), randomized controlled trials with a minimum follow-up of 12 months. The long-term outcomes for these interventions, if implemented in the Dutch diabetic population, were simulated with a computer-based model. Costs and effects were discounted at, respectively, 4 and 1.5% annually. A lifelong time horizon was applied. Probabilistic sensitivity analyses were performed, taking account of variability in intervention costs and (long-term) treatment effects. RESULTS Seven trials with 147-5,145 participants met our predefined criteria. All interventions improved cardiovascular risk factors at > or =1 year follow-up and were projected to reduce cardiovascular morbidity over lifetime. The interventions resulted in an average gain of 0.01-0.14 quality-adjusted life-years (QALYs) per participant. Health benefits were generally achieved at reasonable costs (< or =euro50,000/QALY). A self-management education program (X-PERT) and physical activity counseling achieved the best results with > or =0.10 QALYs gained and > or =99% probability to be very cost-effective (< or =euro20,000/QALY). CONCLUSIONS Implementation of lifestyle interventions would probably yield important health benefits at reasonable costs. However, essential evidence for long-term maintenance of health benefits was limited. Future research should be focused on long-term effectiveness and multiple treatment strategies should be compared to determine incremental costs and benefits of one over the other.

The use of group dynamics strategies to enhance cohesion in a lifestyle intervention program for obese children

Background

Most research pertaining to childhood obesity has assessed the effectiveness of preventative interventions, while relatively little has been done to advance knowledge in the treatment of obesity. Thus, a 4-week family- and group-based intervention utilizing group dynamics strategies designed to increase cohesion was implemented to influence the lifestyles and physical activity levels of obese children.

Methods/Design

This paper provides an overview of the rationale for and implementation of the intervention for obese children and their families. Objectives of the intervention included the modification of health behaviors and cohesion levels through the use of group dynamics strategies. To date, a total of 15 children (7 boys and 8 girls, mean age = 10.5) and their families have completed the intervention (during the month of August 2008). Physiological and psychological outcomes were assessed throughout the 4-week intervention and at 3-, 6-, and 12-month follow-up periods.

Discussion

It is believed that the information provided will help researchers and health professionals develop similar obesity treatment interventions through the use of evidence-based group dynamics strategies. There is also a need for continued research in this area, and it is our hope that the Children's Health and Activity Modification Program (C.H.A.M.P.) will provide a strong base from which others may build.

Lifestyle intervention for type 2 diabetes patients: trial protocol of The Copenhagen Type 2 Diabetes Rehabilitation Project

BACKGROUND

Current guidelines recommend education, physical activity and changes in diet for type 2 diabetes patients, yet the composition and organization of non-pharmacological care are still controversial. Therefore, it is very important that programmes aiming to improve non-pharmacological treatment of type 2 diabetes are developed and evaluated. The Copenhagen Type 2 Diabetes Rehabilitation Project aims to evaluate the effectiveness of a new group-based lifestyle rehabilitation programme in a Health Care Centre in primary care.

METHODS/DESIGN

The group-based diabetes rehabilitation programme consists of empowerment-based education, supervised exercise and dietary intervention. The effectiveness of this multi-disciplinary intervention is compared with conventional individual counselling in a Diabetes Outpatient Clinic and evaluated in a prospective and randomized controlled trial. During the recruitment period of 18 months 180 type 2 diabetes patients will be randomized to the intervention group and the control group. Effects on glycaemic control, quality of life, self-rated diabetes symptoms, body composition, blood pressure, lipids, insulin resistance, beta-cell function and physical fitness will be examined after 6, 12 and 24 months.

DISCUSSION

The Copenhagen Type 2 Diabetes Rehabilitation Project evaluates a multi-disciplinary non-pharmacological intervention programme in a primary care setting and provides important information about how to organize non-pharmacological care for type 2 diabetes patients.

Supporting diabetes self-management in primary care: pilot-study of a group-based programme focusing on diet and exercise

AIMS

To develop and implement a group self-management education programme for people with type 2 diabetes at the community level in primary care. This pilot-study intended to evaluate the feasibility, acceptability and long-term effects (12-18 months) of this programme on emotional distress, HbA1c, BMI and actual behaviour.

METHODS

An empowerment-based, theory-driven education programme was evaluated in a before-after design. The programme focused on behaviour assessment, goal-setting, problem solving and tailored information. A diabetes specialist nurse conjointly with a dietician or psychologist led five 2-hour sessions and a follow-up meeting after 3 months.

RESULTS

Forty-four people participated in 5 groups. BMI decreased with 0.45 kg/m(2) (95%CI 0.01-0.89) at 12-month and with 0.53 kg/m(2) (95%CI 0.02-1.04) at 18-month follow-up. HbA1c declined from 7.4% (+/-1.3) to 6.8% (+/-0.8) (p=0.040) and the PAID-score diminished from 28 (+/-20) to 18 (+/-13) (p=0.006) at 12-month post-intervention. These changes were only partly sustained at 18-month follow-up. Actual behaviour changed modestly.

CONCLUSION

Introducing the group education programme in primary healthcare is worthwhile (feasibility and effectiveness). A detailed description of the intervention is offered. Further research should explore the actual education process in greater depth.

Perceptions of a service redesign by adults living with type 2 diabetes

AIM

This article is a report of a study conducted to explore the perceptions of adults with type 2 diabetes towards the service redesign.

BACKGROUND

Diabetes is reaching epidemic proportions and the management of this chronic illness is changing in response to this challenge. In the United Kingdom, there is ongoing restructuring of healthcare services for people with chronic illnesses to ensure that their general health and clinical needs are met predominantly in primary care.

METHOD

An explorative qualitative approach was used. Eight focus groups were conducted with 35 people with type 2 diabetes in one urban location between 2003 and 2004. Five focus groups were conducted with people who had recently experienced the restructured service and three groups with people who had up to 2 years' experience of the new service. Concurrent data collection and thematic analysis were conducted by three researchers and credibility and verification sought by feedback to participants.

FINDINGS

Five main themes were identified: impact of living with diabetes; understanding diabetes; drivers for organizational change; care in context and individual concerns. Participants identified issues for ongoing development of the service.

CONCLUSION

People with type 2 diabetes appreciate their care management within the primary care setting where there has been investment in staff to deliver this care. Healthcare resources are required to support the development of staff and the necessary infrastructure to undertake management in primary care. Policy makers need to address the balance of resources between primary and secondary care.

A national consensus on outcomes and indicators for diabetes patient education

AIM

To develop a national evidence and consensus position on the desired goals, outcomes and indicators of diabetes patient education (DPE).

METHODS

A mixture of qualitative and quantitative methods were used including: (i) literature reviews to identify existing definitions, issues and work in the area; (ii) interviews with key opinion leaders; (iii) focus groups with people with diabetes; (iv) a national survey of diabetes education service providers; (v) a systematic consultation process culminating in a national stakeholder forum.

RESULTS

Three overarching goals were identified as the main purpose of diabetes patient education: (i) optimal adjustment to living with diabetes, (ii) optimal health outcomes and (iii) optimal cost-effectiveness (for the individual and for society). Given the difficulty in attributing cause and effect between education and clinical or cost outcomes and that mechanisms already exist for collecting data on clinical endpoints and surrogate indicators, the development of education indicators concentrated on the goal of optimal adjustment to living with diabetes. Four key outcomes for this goal were listed in order as either directly attributable to DPE or in which DPE plays a discernable role: knowledge and understanding, self-determination, self-management and psychological adjustment.

CONCLUSIONS

The consensus position represents a sound evidence-informed platform on which diabetes education policy, programmes, data collection and research can be based. However, further work was required to test and make recommendations about applying potentially relevant psychometric tools to measure changes in the identified indicators.

Development of a diabetes education program for youth with type 2 diabetes

PURPOSE

The purpose of this article is to present the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TOD2AY) study and a description of the implementation of the standard diabetes education (SDE) program.

METHODS

A total of 218 participants (one third of the eventual sample of 750) were initially enrolled in the study. To date, the mean age of participants was 14.3 + 2.1 years, with 63% being female. Families of study participants were largely low or middle income (more than half report family income <$35 000) and about three-quarters were minority.

RESULTS

More than three-quarters (79%) of families achieved full mastery of the entire SDE program. Mastery required on average 5.5 + 1.3 sessions. In addition, 62% of the families were able to achieve mastery of the session topic in a single visit.

CONCLUSIONS

In summary, the TOD2AY study SDE program fills the need for effective, engaging materials for youth and their families to use in mastering essential type 2 diabetes skills and knowledge.

UK self-care support initiatives for older patients with long-term conditions: a review

OBJECTIVES

Supporting self-care for people with long-term conditions is an aim of UK health policy. As many with long-term conditions are older it is of interest to explore which self-care support interventions have positive impacts for this group. This review explores what types of intervention have been reported in the UK and their impact upon older people.

METHODS

Studies were identified using existing reviews, electronic databases and through hand searching journals. After inclusion and exclusion criteria were applied data were extracted from 18 studies. These were summarized in a narrative synthesis supported by summary tables.

RESULTS

All studies described interventions to support self-care, many targeted at people with arthritis. All used patient education, usually delivered to groups by a range of professionals. The majority of studies reported some significant positive outcomes, most frequently changes in physical functioning, illness knowledge and increased self-efficacy. The average age of participants was 60.

DISCUSSION

This review shows that self-care interventions have had positive effects for older participants but it remains unknown how best to support self-care in participants over 75, a group of people with long-term conditions who may have different needs.

Chronic disease self-management: implementation with and within Australian general practice

Although there is evidence for the effectiveness of self-management support, there has been limited engagement of Australian general practice staff with self-management support provided by other services. Efforts to integrate self-management support into general practice have also been challenging, largely because of capacity constraints and the difficulties of incorporating it into existing work practices. A broader systemic approach is needed, including a collaborative approach between providers, a range of self-management support options, training of general practice staff, and changes to the organisation of services and the way in which they relate to each other. The expanding role of practice nurses, new models of integrated primary health care and changes to the role of the Divisions of General Practice present an opportunity for this to be incorporated "from the ground up".

Individual patient education for people with type 2 diabetes mellitus

BACKGROUND

Type 2 diabetes is a common and costly chronic disease which is associated with significant premature mortality and morbidity. Although patient education is an integral component of diabetes care, there remain uncertainties regarding the effectiveness of different methods and modes of education.

OBJECTIVES

To evaluate the effectiveness of individual patient education on metabolic control, diabetes knowledge and psychosocial outcomes.

SEARCH STRATEGY

Multiple electronic bibliographic databases were searched, including The Cochrane Library, MEDLINE, Premedline, ERIC, Biosis, AMED, Psychinfo, EMBASE, CINAHL, APAIS-health, Australian Medical Index, Web of Science, dissertation abstracts and Biomed Central.

SELECTION CRITERIA

Randomized controlled and controlled clinical trials which evaluated individual education for adults with type 2 diabetes. The intervention was individual face-to-face patient education while control individuals received usual care, routine treatment or group education. Only studies that assessed outcome measures at least six months from baseline were included.

DATA COLLECTION AND ANALYSIS

Information was extracted by two reviewers who summarized both study characteristics and outcome statistics. A meta-analysis using a fixed-effect model was performed if there were adequate studies with a specified outcome of sufficient homogeneity. For outcomes where there were too few studies or the assessment measurements were not standardized or variable, the results were summarised qualitatively.

MAIN RESULTS

Nine studies involving 1359 participants met the inclusion criteria. Six studies compared individual education to usual care and three compared individual education to group education (361 participants). There were no long-term studies and overall the quality of the studies was not high. In the six studies comparing individual face-to-face education to usual care, individual education did not significantly improve glycaemic control (weighted mean difference (WMD) in HbA1c -0.1% (95% confidence interval (CI) -0.3 to 0.1, P = 0.33) over a 12 to 18 month period. However, there did appear to be a significant benefit of individual education on glycaemic control in a subgroup analysis of three studies involving participants with a higher mean baseline HbA1c greater than 8% (WMD -0.3% (95% CI -0.5 to -0.1, P = 0.007). In the two studies comparing individual to group education, there was no significant difference in glycaemic control between individual or group education at 12 to 18 months with a WMD in HbA1c of 0.03% (95% CI -0.02 to 0.1, P = 0.22). There was no significant difference in the impact of individual versus usual care or group education on body mass index systolic or diastolic blood pressure. There were too few studies to perform a meta-analysis on the effect of individual education on dietary self management, diabetes knowledge, psychosocial outcomes and smoking habits. No data were available on the other main outcome measures of diabetes complications or health service utilization and cost analysis in these studies.

AUTHORS' CONCLUSIONS

This systematic review suggests a benefit of individual education on glycaemic control when compared with usual care in a subgroup of those with a baseline HbA1c greater than 8%. However, overall there did not appear to be a significant difference between individual education and usual care. In the small number of studies comparing group and individual education, there was an equal impact on HbA1c at 12 to 18 months. Additional studies are needed to delineate these findings further.

Predictors and effectiveness of diabetes self-management education in clinical practice

OBJECTIVE

To describe the demographic and clinical predictors of attendance at a diabetes education center (DEC) for self-management education, and to compare subsequent quality of care indicators between attendees and non-attendees.

METHODS

DEC attendance in 2002 was determined from a written questionnaire completed by 781 adults with diabetes across Ontario, Canada. Predictors of attendance and quality of care indicators were defined from the questionnaire and from linkage with health care administrative data. A multivariate logistic regression model was built to find the independent predictors of attendance, while quality of care was evaluated using propensity score methods.

RESULTS

30% of survey participants reported attending a DEC in 2002. Independent predictors of attendance were shorter duration of diabetes, receiving regular primary care, receiving regular diabetes specialist care and single marital status. Attendees were more likely to receive a retinal screening examination in the following 2 years than non-attendees.

CONCLUSION

Receiving regular primary care was the strongest predictor of attending a DEC, suggesting that DECs are not substitute providers of diabetes care for people without a regular physician. Increased retinal screening among DEC attendees suggests that self-management education improved their self-efficacy to ensure adequate screening was performed.

PRACTICE IMPLICATIONS

The findings characterize the types of people who attend DECs, which may lead to identification and targeting of inequities in access. The findings also highlight the influence diabetes education can have on quality of care in real-world practice.

A systematic review of the effectiveness of group versus individual treatments for adult obesity

BACKGROUND

Both group and individual modes of delivery are employed for obesity treatments. Commercial weight loss groups commonly employ group-based delivery, while many clinical based settings employ one-to-one delivery. We systematically reviewed randomised controlled trials of treatments for adult obesity to compare the effectiveness of group-based to individual-based modes of treatment delivery.

METHODS

We searched 7 electronic databases and 2 journals and reviewed secondary references, based on a priori criteria to systematically review: randomised controlled trials of obesity treatments, participants with BMI >or=28 kg/m(2), age >or=18 years, comparison groups including at least 1 group-based and 1 individual-based treatment group, and follow-up >or=1 year. We extracted data and conducted meta-analysis of weight change.

RESULTS

Eleven comparison groups from 5 qualifying trials were obtained, representing a total participant pool of 336. Significantly greater (p = 0.03) weight change at 12 months was found in group-based over individualbased treatment, and sub-analyses showed that increased effectiveness was associated with the use of financial reward and psychologist-led interventions.

CONCLUSION

Group-based interventions were more effective than individual-based interventions among a predominantly female participant pool receiving psychologist-led interventions. Future studies to explore differences by professional group and interventions among men, which are accompanied by economic evaluation, are recommended.

Does patient education facilitate diabetic patients' possibilities to reach national treatment targets? A national survey in Swedish primary healthcare

OBJECTIVE

To describe how patient education is arranged in Swedish primary healthcare (PHC) and to assess whether the type of patient education and individual goal setting have an impact on diabetic patients' possibilities of reaching national treatment targets.

DESIGN

A Swedish national survey.

SETTING

Swedish PHC.

SUBJECTS

Data from 485 primary healthcare centres (PHCCs) and 91,637 diabetic patients reported by the PHCCs to the National Diabetes Register in 2006.

MAIN OUTCOME MEASURES

Description of how patient education is arranged, HbA(1c), body mass index, cholesterol, blood pressure, and physical activity.

RESULTS

Of the PHCCs that reported how they performed the individual counselling, 50% reported checklist-driven counselling and 8% individualized counselling based on patients' needs. A total of 105 PHCCs reported that they arranged group education. Of these, 67% used pre-planned programmes and 9% individualized the programme to the patients' needs. The majority of PHCCs (96%) reported that they set individual goals (HbA(1c), blood pressure, lipids, and lifestyle). A minority of the PHCCs (27%) reported that the patients were involved in the final decision concerning their goals. Individual goal-setting facilitated patients' possibilities of reaching treatment targets. Goal-setting, list size of PHCCs, and personnel resources explained a variance of 2.1-5.7%. Neither individual counselling (checklist-driven or individualized to patients' needs) nor group education had an impact on patients' possibilities of reaching the targets.

CONCLUSION

The current study indicates that improvement is needed in patient education in PHC to facilitate diabetic patients' possibilities of reaching national treatment targets.

The effect of adding group-based counselling to individual lifestyle counselling on changes in dietary intake. The Inter99 study--a randomized controlled trial

BACKGROUND

Few studies have investigated the specific effect of single intervention components in randomized controlled trials. The purpose was to investigate the effect of adding group-based diet and exercise counselling to individual life-style counselling on long-term changes in dietary habits.

METHODS

The study was a randomized controlled intervention study. From a general Danish population, aged 30 to 60 years (n = 61,301), two random sample were drawn (group A, n = 11,708; group B, n = 1,308). Subjects were invited for a health screening program. Participation rate was 52.5%. All participants received individual life-style counselling. Individuals at high risk of ischemic heart disease in group A were furthermore offered group-based life-style counselling. The intervention was repeated for high-risk individuals after one and three years. At five-year follow-up all participants were invited for a health examination. High risk individuals were included in this study (n = 2 356) and changes in dietary intake were analyzed using multilevel linear regression analyses.

RESULTS

At one-year follow-up group A had significantly increased the unsaturated/saturated fat ratio compared to group B and in men a significantly greater decrease in saturated fat intake was found in group A compared to group B (net change: -1.13 E%; P = 0.003). No differences were found between group A and B at three-year follow-up. At five-year follow-up group A had significantly increased the unsaturated/saturated fat ratio (net change: 0.09; P = 0.01) and the fish intake compared to group B (net change: 5.4 g/day; P = 0.05). Further, in men a non-significant tendency of a greater decrease was found at five year follow-up in group A compared to group B (net change: -0.68 E%; P = 0.10). The intake of fibre and vegetables increased in both groups, however, no significant difference was found between the groups. No differences between groups were found for saturated fat intake in women.

CONCLUSION

Offering group-based counselling in addition to individual counselling resulted in small, but significantly improved dietary habits at five-year follow-up and a tendency of better maintenance, compared to individual counselling alone.

TRIAL REGISTRATION

The Inter99 study was approved by the local Ethics Committee (KA 98 155) and is registered with ClinicalTrials.gov (registration number: NCT00289237).

Cochrane reviews of educational and self-management interventions to guide nursing practice: a review

BACKGROUND

The burden of chronic disease on healthcare services worldwide is growing and the increased development of educational interventions which help patients to better manage their own conditions is evident internationally.

OBJECTIVES

This paper reports on findings of a review of Cochrane systematic reviews of interventions designed to improve patients' knowledge and skills to manage chronic disease, with particular reference to nursing contribution and practice.

METHODS

Thirty Cochrane systematic reviews were identified as meeting the inclusion criteria. Data were extracted and summarised.

FINDINGS

The majority of reviews included in this paper were judged by Cochrane reviewers to provide inadequate evidence (n=18, 60%) of the effectiveness of the interventions reviewed. Information on the professional delivering the interventions was often not available, although 77% (23) of reviews mentioned that nurses were involved in a proportion of studies.

CONCLUSION

Educational programmes have definite benefits for patients suffering from asthma and are promising for interventions in areas such as diabetes mellitus, epilepsy and mental health. However, it still is not clear what the active ingredients of many successful interventions are.

Synchronous Provider Visit and Self-management Education Improves Glycemic Control in Hispanic Patients With Long-Standing Type 2 Diabetes

Purpose The purpose of this study was to evaluate the efficacy of a multidisciplinary diabetes self-management program. The study focused on improving diabetes control by synchronizing regularly scheduled provider visits with a multidisciplinary diabetes education program. This intervention was instituted in Hispanic patients with long-standing poorly controlled type 2 diabetes.

Methods The study was initiated as a performance improvement project. A group of 44 type 2 diabetes patients followed by the internal medicine faculty with HbA1c levels greater than 9.5 over a 12-month period was identified. Twenty-three of the identified patients were enrolled in a synchronous care group. A cohort control group of the remaining 21 patients not participating in the intervention was followed with routine care. The intervention group shared similar demographic characteristics, medication regimens, initial diabetes control, and a number of provider visits with the control group. The primary outcome of interest for the study is the HbA1c level.

Results The findings demonstrated that our synchronous management approach significantly improved HbA1c level over standard management for medically indigent Hispanic patients with long-standing poorly controlled type 2 diabetes (P < .001). The majority of the patients (89%) in the Intensive Management Group had declines in HbA1c level from baseline, compared to the Standard Management Group (60%, P = .04).

Conclusion The temporal linkage between routine provider visits and a diabetes self-management education intervention in poorly controlled Hispanic patients with long-standing type 2 diabetes led to a significant improvement in HbA1c levels.

Improving the prevention and management of chronic disease in low-income and middle-income countries: a priority for primary health care

The burden of chronic diseases, such as heart disease, cancer, diabetes, and mental disorders is high in low-income and middle-income countries and is predicted to increase with the ageing of populations, urbanisation, and globalisation of risk factors. Furthermore, HIV/AIDS is increasingly becoming a chronic disorder. An integrated approach to the management of chronic diseases, irrespective of cause, is needed in primary health care. Management of chronic diseases is fundamentally different from acute care, relying on several features: opportunistic case finding for assessment of risk factors, detection of early disease, and identification of high risk status; a combination of pharmacological and psychosocial interventions, often in a stepped-care fashion; and long-term follow-up with regular monitoring and promotion of adherence to treatment. To meet the challenge of chronic diseases, primary health care will have to be strengthened substantially. In the many countries with shortages of primary-care doctors, non-physician clinicians will have a leading role in preventing and managing chronic diseases, and these personnel need appropriate training and continuous quality assurance mechanisms. More evidence is needed about the cost-effectiveness of prevention and treatment strategies in primary health care. Research on scaling-up should be embedded in large-scale delivery programmes for chronic diseases with a strong emphasis on assessment.

Peer advisers compared with specialist health professionals in delivering a training programme on self-management to people with diabetes: a randomized controlled trial

AIMS

To assess the effectiveness and acceptability of peer advisers in diabetes in delivering a programme of training on self-management for people with diabetes.

METHODS

Adults with diabetes were randomly allocated to an education programme delivered either by trained peer advisers or by specialist health professionals. The primary outcome measure was change in knowledge tested before and at the conclusion of the four courses, each consisting of six sessions. Glycated haemoglobin and Diabetes Care Profile were assessed at baseline and at 6 months. Sessional and end-of-course evaluation responses were analysed, as was the attendance record.

RESULTS

Eighty-three patients were randomized. Of these, 14 failed to attend and two were excluded. Knowledge scores improved significantly in both groups, but there was no difference between the groups for any of the knowledge domains. No difference was noted in the Diabetes Care Profiles or in glycated haemoglobin. The attendance record was similar in both groups. In the post-sessional evaluations, both groups scored highly, with the health professionals significantly more so. The post-course questionnaire exploring patients' understanding and confidence in self-management of specific aspects of diabetes care revealed no difference between the groups.

CONCLUSIONS

Trained patients are as effective in imparting knowledge to their peers as specialist health professionals. Both are also acceptable to patients as trainers. However, lay tutors require to be given appropriate training, specific to the education programme they would be expected to deliver.

Educational interventions for migrant South Asians with Type 2 diabetes: a systematic review

AIMS

To conduct a systematic review to determine the scope of published assessments of educational initiatives for South Asians with Type 2 diabetes living in Western countries and to consider the effectiveness of reported interventions.

METHODS

A range of electronic databases was searched using Medical Subject Headings (MeSH) and free text terms; papers published up to the end of 2007 were considered. Two researchers independently reviewed titles and abstracts and the full text of selected citations. Reference list review and consultation with experts in the field were used to check for completeness of the final sample of studies prior to data extraction.

RESULTS

Only nine studies, including five randomized controlled trials with a combined total of 1004 cases, met our inclusion criteria. The quality of reporting in some studies was limited, e.g. omission of detailed information about ethnicity. Selected studies included a range of group and one-to-one interventions with varied knowledge, psychological and biomedical outcome measures. The effectiveness of the interventions was also variable, and the low number and heterogeneity of the studies made identification of factors linked to effectiveness difficult and meta-analysis inappropriate. However, it appeared that improvements in knowledge levels may be easier to achieve than positive biomedical outcomes, and the need for tailored approaches was suggested.

CONCLUSIONS

Our findings confirm the difficulty of designing, assessing and achieving an impact through educational interventions for migrant South Asians with Type 2 diabetes and emphasize the need for good-quality studies in these high-risk populations.

Culturally appropriate health education for type 2 diabetes mellitus in ethnic minority groups

BACKGROUND

Ethnic minority groups in upper-middle and high income countries tend to be socio-economically disadvantaged and to have higher prevalence of type 2 diabetes than the majority population.

OBJECTIVES

To assess the effectiveness of culturally appropriate diabetes health education on important outcome measures in type 2 diabetes.

SEARCH STRATEGY

We searched the The Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL, ERIC, SIGLE and reference lists of articles. We also contacted authors in the field and handsearched commonly encountered journals.

SELECTION CRITERIA

RCTs of culturally appropriate diabetes health education for people over 16 years with type 2 diabetes mellitus from named ethnic minority groups resident in upper-middle or high income countries.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial quality and extracted data. Where there were disagreements in selection of papers for inclusion, all four authors discussed the studies. We contacted study authors for additional information when data appeared to be missing or needed clarification.

MAIN RESULTS

Eleven trials involving 1603 people were included, with ten trials providing suitable data for entry into meta-analysis. Glycaemic control (HbA1c), showed an improvement following culturally appropriate health education at three months (weight mean difference (WMD) - 0.3%, 95% CI -0.6 to -0.01), and at six months (WMD -0.6%, 95% CI -0.9 to -0.4), compared with control groups who received 'usual care'. This effect was not significant at 12 months post intervention (WMD -0.1%, 95% CI -0.4 to 0.2). Knowledge scores also improved in the intervention groups at three months (standardised mean difference (SMD) 0.6, 95% CI 0.4 to 0.7), six months (SMD 0.5, 95% CI 0.3 to 0.7) and twelve months (SMD 0.4, 95% CI 0.1 to 0.6) post intervention. Other outcome measures both clinical (such as lipid levels, and blood pressure) and patient centred (quality of life measures, attitude scores and measures of patient empowerment and self-efficacy) showed no significant improvement compared with control groups.

AUTHORS' CONCLUSIONS

Culturally appropriate diabetes health education appears to have short term effects on glycaemic control and knowledge of diabetes and healthy lifestyles. None of the studies were long-term, and so clinically important long-term outcomes could not be studied. No studies included an economic analysis. The heterogeneity of studies made subgroup comparisons difficult to interpret with confidence. There is a need for long-term, standardised multi-centre RCTs that compare different types and intensities of culturally appropriate health education within defined ethnic minority groups.
