Behavioral Programs for Type 2 Diabetes Mellitus: A Systematic Review and Network Meta-analysis

Spousal Influence on Diabetes Self-care: Moderating Effects of Distress and Relationship Quality on Glycemic Control

BACKGROUND

Spouses often attempt to influence patients' diabetes self-care. Spousal influence has been linked to beneficial health outcomes in some studies, but to negative outcomes in others.

PURPOSE

We aimed to clarify the conditions under which spousal influence impedes glycemic control in patients with type 2 diabetes. Spousal influence was hypothesized to associate with poorer glycemic control among patients with high diabetes distress and low relationship quality.

METHODS

Patients with type 2 diabetes and their spouses (N = 63 couples) completed self-report measures before patients initiated a 7-day period of continuous glucose monitoring. Mean glucose level and coefficient of variation (CV) were regressed on spousal influence, diabetes distress, relationship quality, and their two- and three-way interactions.

RESULTS

The three-way interaction significantly predicted glucose variability, but not mean level. Results revealed a cross-over interaction between spousal influence and diabetes distress at high (but not low) levels of relationship quality, such that spousal influence was associated with less variability among patients with low distress, but more among those with high distress. Among patients with high distress and low relationship quality, a 1 SD increase in spousal influence predicted a difference roughly equivalent to the difference between the sample mean CV and a CV in the unstable glycemia range.

CONCLUSIONS

This was the first study to examine moderators of the link between spousal influence and glycemic control in diabetes. A large effect was found for glucose variability, but not mean levels. These novel results highlight the importance of intimate relationships in diabetes management.

Diabetes Management in Chronic Kidney Disease: Synopsis of the 2020 KDIGO Clinical Practice Guideline

DESCRIPTION

The Kidney Disease: Improving Global Outcomes (KDIGO) organization developed a clinical practice guideline in 2020 for the management of patients with diabetes and chronic kidney disease (CKD).

METHODS

The KDIGO Work Group (WG) was tasked with developing the guideline for diabetes management in CKD. It defined the scope of the guideline, gathered evidence, determined systematic review topics, and graded evidence that had been summarized by an evidence review team. The English-language literature searches, which were initially done through October 2018, were updated in February 2020. The WG used the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach to appraise evidence and rate the strength of the recommendations. Expert judgment was used to develop consensus practice points supplementary to the evidence-based graded recommendations. The guideline document underwent open public review. Comments from various stakeholders, subject matter experts, and industry and national organizations were considered before the document was finalized.

RECOMMENDATIONS

The guideline includes 12 recommendations and 48 practice points for clinicians caring for patients with diabetes and CKD. This synopsis focuses on the key recommendations pertinent to the following issues: comprehensive care needs, glycemic monitoring and targets, lifestyle interventions, antihyperglycemic therapies, and educational and integrated care approaches.

An Effective Model of Diabetes Care and Education: The ADCES7 Self-Care Behaviors™

PURPOSE

The ADCES7 Self-Care Behaviors^™ (ADCES7) is a robust framework for self-management of diabetes and other related conditions, such as prediabetes and cardiometabolic diseases. It is the position of the Association of Diabetes Care and Education Specialists (ADCES) that at the cornerstone of diabetes self-management education and support, the ADCES7 is the framework for achieving behavior change that leads to effective self-management through improved behavior and clinical outcome measures. The ADCES7 model guides the health care team in effective person-centered collaboration and goal setting to achieve health-related outcomes and improved quality of life. Continued research and evidence are critical to expand this model and broaden its application to other chronic conditions. Given the advances in the science of diabetes management as well as diabetes self-management education and support, ADCES has evaluated the ADCES7 within the framework of these advances, including the digital and dynamic health care landscape.

CONCLUSION

This revised position statement blends the updates in research and ADCES's vision and expansion beyond diabetes to refresh the ADCES7 framework. This revision reflects the perspectives of all members of the health care team as they problem solve with individuals who are at risk for or who have diabetes and related conditions to achieve healthier outcomes.

2017 National Standards for Diabetes Self-Management Education and Support

PURPOSE

The purpose of this study is to review the literature for Diabetes Self-Management Education and Support (DSMES) to ensure the National Standards for DSMES (Standards) align with current evidence-based practices and utilization trends.

METHODS

The 10 Standards were divided among 20 interdisciplinary workgroup members. Members searched the current research for diabetes education and support, behavioral health, clinical, health care environment, technical, reimbursement, and business practice for the strongest evidence that guided the Standards revision.

RESULTS

Diabetes Self-Management Education and Support facilitates the knowledge, skills, and ability necessary for diabetes self-care as well as activities that assist a person in implementing and sustaining the behaviors needed to manage their condition on an ongoing basis. The evidence indicates that health care providers and people affected by diabetes are embracing technology, and this is having a positive impact of DSMES access, utilization, and outcomes.

CONCLUSION

Quality DSMES continues to be a critical element of care for all people with diabetes. The DSMES services must be individualized and guided by the concerns, preferences, and needs of the person affected by diabetes. Even with the abundance of evidence supporting the benefits of DSMES, it continues to be underutilized, but as with other health care services, technology is changing the way DSMES is delivered and utilized with positive outcomes.

Effect of diabetes self-management education (DSME) on glycated hemoglobin (HbA1c) level among patients with T2DM: Systematic review and meta-analysis of randomized controlled trials

BACKGROUND AND AIMS

Type 2 Diabetes mellitus (T2DM) has been a global public health issue causing in physical, financial and psychosocial crises. The aim of this systematic review and meta-analysis (SRMA) was to evaluate the Diabetes Self-Management Education or Support (DSME/S) on glycosylated hemoglobin (HbA1c) among T2DM patients.

METHODS

This SRMA was made according to preferred reporting Items for systematic review and Meta-analysis (PRISMA) guidelines. The relevant articles were searched from four databases: Cochrane Library, MEDLINE (EBSCOhost), MEDLINE/PubMed and SCOPUS. Quality assessment was carried out. Pooled standard mean difference in HbA1c were calculated to obtain the effect size with random effect assumption. Subgroup analysis was conducted for assessing heterogeneity among the studies.

RESULTS

A total of 1312 studies were identified from databases. Among these 25 studies met inclusion criteria. From these 20 were included in the meta-analysis. In meta-analysis a pooled standard mean difference in HbA1c was -0.604 (95% confidence interval = -0.854 -0.353, I² = 90.3, p < 0.001). In subgroup analysis a significant reduction was seen among studies with less than four months, upper middle followed by lower middle income countries (LMICs), Western Pacific (WP) followed by Middle Eastern and Northern African (MENA) regions with moderate to substantial heterogeneity.

CONCLUSION

However, there is paucity of studies in underdeveloped countries. Therefore, further studies validated to these contexts are needed to evaluate the DSME effectiveness.

Barriers to Diabetes Self-Management in a Subset of New Zealand Adults with Type 2 Diabetes and Poor Glycaemic Control

BACKGROUND

Despite the fact that there is an increasingly effective armoury of medications to treat diabetes, many people continue to have substantially elevated blood glucose levels. The purpose of this study was to explore what the barriers to diabetes management are in a cohort of people with diabetes and poor glycaemic control.

METHODS

Qualitative semistructured interviews were carried out with 10 people with diabetes who had known diabetes and a recent HbA1c of >11.3% (100 mmol/mol) to explore their experiences of barriers to diabetes self-management and glycaemic control.

RESULTS

Barriers to diabetes management were based around two key themes: biopsychosocial factors and knowledge about diabetes. Specifically, financial concerns, social stigma, medication side effects, and cognitive impairment due to hyperglycaemia were commonly reported as barriers to medication use. Other barriers included a lack of knowledge about their own condition, poor relationships with healthcare professionals, and a lack of relevant resources to support diet and weight loss.

CONCLUSION

People with diabetes with poor glycaemic control experience many of the same barriers as those reported elsewhere, but also experience issues specifically related to their severe hyperglycaemia. Management of diabetes could be improved via the increased use of patient education and availability of locally relevant resources.

The effectiveness of diabetes self-management education (DSME) on glycemic control among T2DM patients randomized control trial: systematic review and meta-analysis protocol

BACKGROUND

Type 2 Diabetes mellitus (T2DM) has been a global pandemic resulting in physical, financial and psychosocial crises. Thus, it is important to investigate pooled effectiveness of Diabetes Self-Management Education (DSME) on glycemic control among T2DM patients.

OBJECTIVE

The aim of this systematic review and meta-analysis is to investigate the association between DSME or Support (DSME/S) and glycemic control among T2DM patients.

METHODS

The systematic review and meta-analysis will include studies conducted throughout the world from 2010 to 2019. T2DM patients and their clinical, anthropometric, biomarkers from baseline to end line will be recorded. We will search all relevant articles from five databases namely; Cochrane Library, BioMed Central, MEDLINE (EBSCOhost), MEDLINE/PubMed and SCOPUS. Key terms will be used for questing relevant articles. Further efforts will be made to check quality of studies base on quality assessment instruments. Finally, the report will be made according Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. Pooled standard mean difference in HbA1c will be used to calculate the effect size between the variables with random effects analysis assumption. Further subgroup analysis will be carried out for assessing the risk difference among groups.

CONCLUSION

Based on the existing and eligible researches this systematic review and meta-analysis will bring the best evidence on the effectiveness of DSME/S on glycemic control among the T2DM patients. Moreover, the subgroup analysis will inform the effectiveness heterogeneity based on continent, International Diabetes Federation (IDF) region, intervention period, World bank economic classification and glycemic markers used to follow the patients. The proposed review has been registered in the International PROSPERO website with registration number CRD42020124236.

Glycaemic trajectory and predictors of suboptimal glycaemic control in people with type 2 diabetes

We aimed to describe the glycaemic trajectory and define characteristics associated with suboptimal glycaemic control in the type 2 diabetes clinic. Higher glycosylated haemoglobin (HbA1c) at 1 year was associated with higher baseline HbA1c, concurrent anti-depressant or antipsychotic medication, higher bodyweight and low treatment adherence. These characteristics may help identify patients unlikely to attain HbA1c treatment targets and be better served by a different model of care.

Diabetes self-management education and support for adults with newly diagnosed type 2 diabetes mellitus: A systematic review and meta-analysis of randomized controlled trials

This systematic review aimed to identify the effectiveness of diabetes self-management education and support (DSMES) among adults within 12 months of diagnosis of type 2 diabetes mellitus (T2DM). We searched the Cochrane Library, MEDLINE, CINAHL, PsycINFO, ERIC, and other sources up to March 2019 to detect randomized controlled trials in the last decade based on the global guidelines' definition of DSMES. Data were categorized into biomedical, psychosocial, and behavioral outcomes and synthesized using a random-effects model. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation system. We scrutinized 12 studies that enrolled 2,386 adults with newly diagnosed T2DM. Biomedical outcomes presented the pooled effects of HbA1c -0.21% (95% confidence interval, -0.38, -0.04), body weight -2.36 kg (-5.77, 1.05), and waist circumference -1.8 cm (-5.63, 2.04) when the data from the two studies with low risk of bias were combined (N = 1,082). Psychosocial and behavioral effects were inconclusive owing to mixed results from various scales and reporting. The quality of the body of evidence was low. DSMES within 12 months of T2DM diagnosis might affect patient-centered outcomes. Further studies with higher precision using standardized measurement methods are required.

Health system interventions for adults with type 2 diabetes in low- and middle-income countries: A systematic review and meta-analysis

BACKGROUND

Effective health system interventions may help address the disproportionate burden of diabetes in low- and middle-income countries (LMICs). We assessed the impact of health system interventions to improve outcomes for adults with type 2 diabetes in LMICs.

METHODS AND FINDINGS

We searched Ovid MEDLINE, Cochrane Library, EMBASE, African Index Medicus, LILACS, and Global Index Medicus from inception of each database through February 24, 2020. We included randomized controlled trials (RCTs) of health system interventions targeting adults with type 2 diabetes in LMICs. Eligible studies reported at least 1 of the following outcomes: glycemic change, mortality, quality of life, or cost-effectiveness. We conducted a meta-analysis for the glycemic outcome of hemoglobin A1c (HbA1c). GRADE and Cochrane Effective Practice and Organisation of Care methods were used to assess risk of bias for the glycemic outcome and to prepare a summary of findings table. Of the 12,921 references identified in searches, we included 39 studies in the narrative review of which 19 were cluster RCTs and 20 were individual RCTs. The greatest number of studies were conducted in the East Asia and Pacific region (n = 20) followed by South Asia (n = 7). There were 21,080 total participants enrolled across included studies and 10,060 total participants in the meta-analysis of HbA1c when accounting for the design effect of cluster RCTs. Non-glycemic outcomes of mortality, health-related quality of life, and cost-effectiveness had sparse data availability that precluded quantitative pooling. In the meta-analysis of HbA1c from 35 of the included studies, the mean difference was -0.46% (95% CI -0.60% to -0.31%, I2 87.8%, p < 0.001) overall, -0.37% (95% CI -0.64% to -0.10%, I2 60.0%, n = 7, p = 0.020) in multicomponent clinic-based interventions, -0.87% (-1.20% to -0.53%, I2 91.0%, n = 13, p < 0.001) in pharmacist task-sharing studies, and -0.27% (-0.50% to -0.04%, I2 64.1%, n = 7, p = 0.010) in trials of diabetes education or support alone. Other types of interventions had few included studies. Eight studies were at low risk of bias for the summary assessment of glycemic control, 15 studies were at unclear risk, and 16 studies were at high risk. The certainty of evidence for glycemic control by subgroup was moderate for multicomponent clinic-based interventions but was low or very low for other intervention types. Limitations include the lack of consensus definitions for health system interventions, differences in the quality of underlying studies, and sparse data availability for non-glycemic outcomes.

CONCLUSIONS

In this meta-analysis, we found that health system interventions for type 2 diabetes may be effective in improving glycemic control in LMICs, but few studies are available from rural areas or low- or lower-middle-income countries. Multicomponent clinic-based interventions had the strongest evidence for glycemic benefit among intervention types. Further research is needed to assess non-glycemic outcomes and to study implementation in rural and low-income settings.

Effective SLOPE: EffectS of Lifestyle interventions in Older PEople with obesity: a systematic review and network meta-analysis protocol

INTRODUCTION

Obesity is highly prevalent in older adults aged 65 years or older. Different lifestyle interventions (diet, exercise, self-management) are available but benefits and harms have not been fully quantified comparing all available health promotion interventions. Special consideration must be given to functional outcomes and possible adverse effects (loss of muscle and bone mass, hypoglycaemia) of weight loss interventions in this age group. The objective of this study is to synthesise the evidence regarding the effects of different types and modalities of lifestyle interventions, or their combinations, on physical function and obesity-related outcomes such as body composition in older adults with obesity.

METHODS AND ANALYSES

Six databases (Medline, Embase, Cochrane Central Register of Controlled Trials, Cumulated Index to Nursing and Allied Health Literature (CINAHL), Psychinfo and Web of Science) and two trial registries (Clinicaltrials.gov and the WHO International Clinical Trials Registry Platform) will be searched for randomised controlled trials of lifestyle interventions in older adults with obesity. Screening (title/abstract and full-text) and data extraction of references as well as assessment of risk of bias and rating of the certainty of evidence (Grading of Recommendations, Assessment, Development and Evaluation for network meta-analyses) will be performed by two reviewers independently. Frequentist random-effects network meta-analyses will be conducted to determine the pooled effects from each intervention.

ETHICS AND DISSEMINATION

We will submit our findings to peer-reviewed journals and present at national and international conferences as well as in scientific medical societies. Patient-targeted dissemination will involve local and national advocate groups.

Scalable solution for delivery of diabetes self-management education in Thailand (DSME-T): a cluster randomised trial study protocol

INTRODUCTION

Type 2 diabetes mellitus is among the foremost health challenges facing policy makers in Thailand as its prevalence has more than tripled over the last two decades, accounting for considerable death, disability and healthcare expenditure. Diabetes self-management education (DSME) programmes show promise in improving diabetes outcomes, but this is not routinely used in Thailand. This study aims to test a culturally tailored DSME model in Thailand, using a three-arm cluster randomised controlled trial comparing a nurse-led model, a peer-assisted model and standard care. We will test which model is effective and cost effective to improve cardiovascular risk and control of blood glucose among people with diabetes.

METHODS AND ANALYSIS

21 primary care units in northern Thailand will be randomised to one of three interventions, enrolling a total of 693 patients. The primary care units will be randomised (1:1:1) to participate in a culturally-tailored DSME intervention for 12 months. The three-arm trial design will compare effectiveness of nurse-led, peer-assisted (Thai village health volunteers) and standard care. The primary trial outcomes are changes in haemoglobin A1c and cardiovascular risk score. A process evaluation and cost effectiveness evaluation will be conducted to produce policy relevant guidance for the Thai Ministry of Public Health. The planned trial period will start in January 2020 and finish October 2021.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from Thailand and the UK. We will share our study data with other researchers, advertising via our publications and web presence. In particular, we are committed to sharing our findings and data with academic audiences in Thailand and other low-income and middle-income countries.

Effectiveness of Lifestyle Intervention for Type 2 Diabetes in Primary Care: the REAL HEALTH-Diabetes Randomized Clinical Trial

BACKGROUND

Intensive lifestyle interventions (LI) improve outcomes in obesity and type 2 diabetes but are not currently available in usual care.

OBJECTIVE

To compare the effectiveness and costs of two group LI programs, in-person LI and telephone conference call (telephone LI), to medical nutrition therapy (MNT) on weight loss in primary care patients with type 2 diabetes.

DESIGN

A randomized, assessor-blinded, practice-based clinical trial in three community health centers and one hospital-based practice affiliated with a single health system.

PARTICIPANTS

A total of 208 primary care patients with type 2 diabetes, HbA1c 6.5 to < 11.5, and BMI > 25 kg/m² (> 23 kg/m² in Asians).

INTERVENTIONS

Dietitian-delivered in-person or telephone group LI programs with medication management or MNT referral.

MAIN MEASURES

Primary outcome: mean percent weight change.

SECONDARY OUTCOMES

5% and 10% weight loss, change in HbA1c, and cost per kilogram lost.

KEY RESULTS

Participants' mean age was 62 (SD 10) years, 45% were male, and 77% were White, with BMI 35 (SD 5) kg/m² and HbA1c 7.7 (SD 1.2). Seventy were assigned to in-person LI, 72 to telephone LI, and 69 to MNT. The mean percent weight loss (95% CI) at 6 and 12 months was 5.6% (4.4-6.8%) and 4.6% (3.1-6.1%) for in-person LI, 4.6% (3.3-6.0%) and 4.8% (3.3-6.2%) for telephone LI, and 1.1% (0.2-2.0%) and 2.0% (0.9-3.0%) for MNT, with statistically significant differences between each LI arm and MNT (P < 0.001) but not between LI arms (P = 0.63). HbA1c improved in all participants. Compared with MNT, the incremental cost per kilogram lost was $789 for in-person LI and $1223 for telephone LI.

CONCLUSIONS

In-person LI or telephone group LI can achieve good weight loss outcomes in primary care type 2 diabetes patients at a reasonable cost.

Study protocol: Using peer support to aid in prevention and treatment in prediabetes (UPSTART)

BACKGROUND

There is an urgent need to develop and evaluate effective and scalable interventions to prevent or delay the onset of type 2 diabetes mellitus (T2DM).

METHODS

In this randomized controlled pragmatic trial, 296 adults with prediabetes will be randomized to either a peer support arm or enhanced usual care. Participants in the peer support arm meet face-to-face initially with a trained peer coach who also is a patient at the same health center to receive information on locally available wellness and diabetes prevention programs, discuss behavioral goals related to diabetes prevention, and develop an action plan for the next week to meet their goals. Over six months, peer coaches call their assigned participants weekly to provide support for weekly action steps. In the final 6 months, coaches call participants at least once monthly. Participants in the enhanced usual care arm receive information on local resources and periodic updates on available diabetes prevention programs and resources. Changes in A1c, weight, waist circumference and other patient-centered outcomes and mediators and moderators of intervention effects will be assessed.

RESULTS

At least 296 participants and approximately 75 peer supporters will be enrolled.

DISCUSSION

Despite evidence that healthy lifestyle interventions can improve health behaviors and reduce risk for T2DM, engagement in recommended behavior change is low. This is especially true among racial and ethnic minority and low-income adults. Regular outreach and ongoing support from a peer coach may help participants to initiate and sustain healthy behavior changes to reduce their risk of diabetes.

TRIAL REGISTRATION

The ClinicalTrials.gov registration number is NCT03689530.

Layperson-Led vs Professional-Led Behavioral Interventions for Weight Loss in Pediatric Obesity: A Systematic Review and Meta-analysis

IMPORTANCE

The appropriate approach for weight loss among children and adolescents with overweight and obesity remains unclear.

OBJECTIVE

To evaluate the difference in the treatment outcomes associated with behavioral weight loss interventions led by laypersons and professionals in comparison with unsupervised control arms among children and adolescents with overweight and obesity.

DATA SOURCES

For this systematic review and meta-analysis, the Medical Literature Analysis and Retrieval System Online (MEDLINE), Embase, the Cochrane Library, and Cumulative Index of Nursing and Allied Health Literature (CINAHL) databases were searched from January 1, 1996, to June 1, 2019.

STUDY SELECTION

Included in this study were randomized clinical trials (RCTs) of behavioral interventions lasting at least 12 weeks for children and adolescents (aged 5-18 years) with overweight and obesity. Exclusion criteria included non-RCT studies, interventions lasting less than 12 weeks, adult enrollment, participants with other medical diagnoses, pharmacological treatment use, and articles not written in English. Two of 6 reviewers independently screened all citations. Of 25 586 citations, after duplicate removal, 78 RCTs (5780 participants) met eligibility criteria.

DATA EXTRACTION AND SYNTHESIS

A bayesian framework and Markov chain Monte Carlo simulation methods were used to combine direct and indirect associations. Random-effects and fixed-effect network meta-analysis models were used with the preferred model chosen by comparing the deviance information criteria. This study was registered with the International Prospective Register of Systematic Reviews (PROSPERO) and followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline.

MAIN OUTCOMES AND MEASURES

The immediate and sustained changes in weight and body mass index (BMI) standardized mean difference (SMD) were primary outcomes planned before data collection began, whereas waist circumference and percent body fat were secondary outcomes. The hypothesis being tested was formulated before the data collection.

RESULTS

Of 25 586 citations retrieved, we included 78 RCTs (5780 participants), with a follow-up of 12 to 104 weeks. Compared with the control condition, random-effects models revealed that professional-led weight loss interventions were associated with reductions in weight (mean difference [MD], -1.60 kg [95% CI, -2.30 to -0.99 kg]; 68 trials; P < .001) and BMI (SMD, -0.30 [95% CI, -0.39 to -0.20]; 59 trials; P < .001) that were not sustained long term (weight MD, -1.02 kg [95% CI, -2.20 to 0.34 kg]; 21 trials; P = .06; BMI SMD, -0.12 [95% CI, -0.46 to 0.21]; 20 trials; P < .001). There was no association between layperson-led interventions and weight loss in the short-term (MD, -1.40 kg [95% CI, -3.00 to 0.26 kg]; 5 trials; P = .05) or long-term (MD, -0.98 kg [95% CI, -3.60 to 1.80 kg]; 1 trial; P = .23) compared with standard care. No difference was found in head-to-head trials (professional vs layperson MD, -0.25 kg [95% CI -1.90 to 1.30 kg]; 5 trials; P = .38).

CONCLUSIONS AND RELEVANCE

This systematic review and meta-analysis found that professional-led weight loss interventions were associated with short-term but not sustained weight reduction among children and adolescents with overweight or obesity, and the evidence for layperson-led approaches was insufficient to draw firm conclusions.

Influence of sociodemographic characteristics on the preferred format of health education delivery in individuals with type 2 diabetes mellitus and or cardiovascular disease: a questionnaire study

AIM

To examine the influence of sociodemographic factors of interest on preference for a particular health education format among people with type 2 diabetes and/or cardiovascular disease.

METHODS

A questionnaire was used to collect information on the influence of six sociodemographic factors of interest on the preference for health education formats in people with type 2 diabetes and/or cardiovascular disease. Chi-squared tests were used to examine the distribution of preferences between groups. The characteristics of the population preferring the online format were then examined in more detail using logistic regression.

RESULTS

Responses were received from 1559 participants. Overall the preferred health education format was one-to-one learning from a doctor or nurse (67%). Age, gender, diagnosis and educational level all affected the preferences expressed. The characteristics showing most consistent and significant influence were age and educational level. Overall, 29% ranked the online format highly (scores 1 or 2). This group were more likely to be aged < 65 years (P < 0.001) and to have a higher level of educational attainment (upper secondary education or higher; P < 0.001).

CONCLUSIONS

Significant differences between sociodemographic groups exist in preferences for health education formats among people with type 2 diabetes and/or cardiovascular disease. Preferences should be considered when designing educational interventions to ensure they are accessible to the target group and to avoid increases in health inequality.

Clinical and cost-effectiveness of a diabetes education and behavioural weight management programme versus a diabetes education programme in adults with a recent diagnosis of type 2 diabetes: study protocol for the Glucose Lowering through Weight management (GLoW) randomised controlled trial

INTRODUCTION

People with type 2 diabetes (T2D) can improve glycaemic control or even achieve remission through weight loss and reduce their use of medication and risk of cardiovascular disease. The Glucose Lowering through Weight management (GLoW) trial will evaluate whether a tailored diabetes education and behavioural weight management programme (DEW) is more effective and cost-effective than a diabetes education (DE) programme in helping people with overweight or obesity and a recent diagnosis of T2D to lower their blood glucose, lose weight and improve other markers of cardiovascular risk.

METHODS AND ANALYSIS

This study is a pragmatic, randomised, single-blind, parallel group, two-arm, superiority trial. We will recruit 576 adults with body mass index>25 kg/m² and diagnosis of T2D in the past 3 years and randomise them to a tailored DEW or a DE programme. Participants will attend measurement appointments at a local general practitioner practice or research centre at baseline, 6 and 12 months. The primary outcome is 12-month change in glycated haemoglobin. The effect of the intervention on the primary outcome will be estimated and tested using a linear regression model (analysis of covariance) including randomisation group and adjusted for baseline value of the outcome and the randomisation stratifiers. Participants will be included in the group to which they were randomised, under the intention-to-treat principle. Secondary outcomes include 6-month and 12-month changes in body weight, body fat percentage, systolic and diastolic blood pressure and lipid profile; probability of achieving good glycaemic control; probability of achieving remission from diabetes; probability of losing 5% and 10% body weight and modelled cardiovascular risk (UKPDS). An intention-to-treat within-trial cost-effectiveness analysis will be conducted from NHS and societal perspectives using participant-level data. Qualitative interviews will be conducted with participants to understand why and how the programme achieved its results and how participants manage their weight after the programme ends.

ETHICS AND DISSEMINATION

Ethical approval was received from East of Scotland Research Ethics Service on 15 May 2018 (18/ES/0048). This protocol (V.3) was approved on 19 June 2019. Findings will be published in peer-reviewed scientific journals and communicated to other stakeholders as appropriate.

Systematic review of salutogenic-oriented lifestyle randomised controlled trials for adults with type 2 diabetes mellitus

OBJECTIVE

Describe the characteristics (development, intensity, deliverers, setting, strategies) and assess the effect of salutogenic-oriented lifestyle interventions on physical and psychosocial health outcomes in adults with type 2 diabetes mellitus (T2DM).

METHOD

PubMed, Scopus and PsycINFO were systematically searched for randomised controlled trials (RCTs) published up to August 2019 that complied with predefined salutogenic criteria: the participant as a whole, the participant's active involvement and the participant's individual learning process. Characteristics of the salutogenic-oriented interventions with and without significant results were compared and qualitatively summarised.

RESULTS

Twenty-eight RCTs were identified. Salutogenic oriented interventions that significantly improved both physical and psychosocial health were characterized by being based on formative research, culturally targeted, and delivered in 10-20 sessions in group settings, whereas salutogenic oriented interventions that neither improved physical or psychosocial health significantly were characterized by being individually tailored and delivered in less than 10 group sessions in individual settings.

CONCLUSIONS

This systematic review suggests that salutogenic-oriented lifestyle interventions are effective for physical and psychosocial health in the short term. More research is needed to determine how intervention characteristics moderate (long-term) effectiveness.

PRACTICE IMPLICATIONS

The results provide a basis for purposefully developing effective salutogenic interventions for adults with T2DM.

Psychological interventions to improve glycemic control in adults with type 2 diabetes: a systematic review and meta-analysis

The quality of evidence that psychological interventions are effective in improving glycemic control in adults with type 2 diabetes (T2D) is weak.We conducted a systematic review and meta-analysis of psychological interventions in T2D to assess whether their effectiveness in improving glycemic levels has improved over the past 30 years. We applied the protocol of a systematic review and aggregate meta-analysis conducted to January 2003. We added network meta-analysis (NMA) to compare intervention and control group type against usual care. MEDLINE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, EMBASE, Cochrane Controlled Trials Database, Web of Science, and Dissertation Abstracts International were searched from January 2003 to July 2018. Only randomized controlled trials (RCT) of psychological interventions for adults with T2D reported in any language were included. The primary outcome was change in glycemic control (glycated hemoglobin (HbA1c) in mmol/mol). Data were extracted from study reports and authors were contacted for missing data.94 RCTs were eligible for inclusion in the systematic review since the last review. In 70 RCTs (n=14 796 participants) the pooled mean difference in HbA1c in those randomized to psychological intervention compared with control group was -0.19 (95% CI -0.25 to -0.12), equivalent to a reduction in HbA1c of 3.7 mmol/mol, with moderate heterogeneity across studies (I²=64.7%, p<0.001). NMA suggested the probability of intervention effectiveness is highest for self-help materials, cognitive-behavioral therapy, and counseling, compared with usual care. Limitations of this study include that there is a possibility that some studies may have been missed if diabetes did not appear in the title or abstract.The effectiveness of psychological interventions for adults with T2D have minimal clinical benefit in improving glycemic control.

Peer support interventions in type 2 diabetes: Review of components and process outcomes

BACKGROUND

This review seeks to identify (a) the various components and process outcomes of type 2 diabetes peer support (PS) interventions and (b) the measures implemented to monitor intervention fidelity and evaluate outcomes in these studies.

METHODS

The MEDLINE, PubMed, EMBASE (Excerpta Medica Database), CENTRAL (Cochrane Central Register of Controlled Trials), CINAHL (Cumulative Index to Nursing and Allied Health Literature), and PsycINFO databases were searched from inception to May 2019. Two reviewers independently screened and extracted data from eligible articles via the Template for Intervention Description and Replication (TIDieR) checklist (why, what, who provided, how, where, when and how much, tailoring, modifications, and how well).

RESULTS

Twenty-three trials were included. The total number of participants was 7178. Most interventions were in primary care. Although face-to-face was the most common modality of contact, rates of contact were highest for telephone. Potential peer leaders (PLs) were identified primarily through recommendations from health professionals, based on their communication skills, glycosylated hemoglobin (HbA1c), and coaching interest. PLs were mostly female, university educated, and had a long history of diabetes (≥ 10 years). PL training varied significantly in length and content; the two most frequent topics were communication skills and diabetes knowledge. Although several studies implemented methods to evaluate "intervention fidelity," only few rigorously assessed the two key components of fidelity, "adherence" and "competence," through audio- and video-taping or direct observations.

CONCLUSIONS

The impact of PS on participants' health outcomes is well investigated; however, the implementation and evaluation strategies vary significantly across these studies. In the present review, we define the various components of PS interventions and propose suggestions for enhancing the implementation and evaluation of future PS models.

Mapping the Evidence on the Effectiveness of Telemedicine Interventions in Diabetes, Dyslipidemia, and Hypertension: An Umbrella Review of Systematic Reviews and Meta-Analyses

Background

Telemedicine is defined by three characteristics: (1) using information and communication technologies, (2) covering a geographical distance, and (3) involving professionals who deliver care directly to a patient or a group of patients. It is said to improve chronic care management and self-management in patients with chronic diseases. However, currently available guidelines for the care of patients with diabetes, hypertension, or dyslipidemia do not include evidence-based guidance on which components of telemedicine are most effective for which patient populations.

Objective

The primary aim of this study was to identify, synthesize, and critically appraise evidence on the effectiveness of telemedicine solutions and their components on clinical outcomes in patients with diabetes, hypertension, or dyslipidemia.

Methods

We conducted an umbrella review of high-level evidence, including systematic reviews and meta-analyses of randomized controlled trials. On the basis of predefined eligibility criteria, extensive automated and manual searches of the databases PubMed, EMBASE, and Cochrane Library were conducted. Two authors independently screened the studies, extracted data, and carried out the quality assessments. Extracted data were presented according to intervention components and patient characteristics using defined thresholds of clinical relevance. Overall certainty of outcomes was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool.

Results

Overall, 3564 references were identified, of which 46 records were included after applying eligibility criteria. The majority of included studies were published after 2015. Significant and clinically relevant reduction rates for glycated hemoglobin (HbA_1c; ≤−0.5%) were found in patients with diabetes. Higher reduction rates were found for recently diagnosed patients and those with higher baseline HbA_1c (>8%). Telemedicine was not found to have a significant and clinically meaningful impact on blood pressure. Only reviews or meta-analyses reporting lipid outcomes in patients with diabetes were found. GRADE assessment revealed that the overall quality of the evidence was low to very low.

Conclusions

The results of this umbrella review indicate that telemedicine has the potential to improve clinical outcomes in patients with diabetes. Although subgroup-specific effectiveness rates favoring certain intervention and population characteristics were found, the low GRADE ratings indicate that evidence can be considered as limited. Future updates of clinical care and practice guidelines should carefully assess the methodological quality of studies and the overall certainty of subgroup-specific outcomes before recommending telemedicine interventions for certain patient populations.

Novel Digital Architecture of a "Low Carb Program" for Initiating and Maintaining Long-Term Sustainable Health-Promoting Behavior Change in Patients with Type 2 Diabetes

Globally, the burden of noncommunicable diseases such as type 2 diabetes is crippling health care systems. Type 2 diabetes, a disease linked with obesity, affects 1 in every 30 people today and is expected to affect 1 in 10 people by 2030. Current provisions are struggling to manage the trajectory of type 2 diabetes prevalence. Offline, face-to-face education for patients with type 2 diabetes has shown to lack long-term impact or the capacity for widespread democratized adoption. Digitally delivered interventions have been developed for patients with type 2 diabetes, and the evidence shows that some interventions provide the capacity to support hyperpersonalization and real-time continuous support to patients, which can result in significant engagement and health outcomes. However, digital health app engagement is notoriously difficult to achieve. This paper reviews the digital behavior change architecture of the Low Carb Program and the application of health behavioral theory underpinning its development and use in scaling novel methods of engaging the population with type 2 diabetes and supporting long-term behavior change.

Effectiveness of self-management interventions in young adults with type 1 and 2 diabetes: a systematic review and meta-analysis

AIM

Diabetes in young adulthood has been associated with poor outcomes. Self-management is fundamental to good diabetes care, and self-management interventions have been found to improve outcomes in older adults. We performed a systematic review and meta-analysis to assess the effectiveness of self-management interventions in young adults (aged 15-39 years) with type 1 or type 2 diabetes.

METHODS

We searched five databases and two clinical trial registries from 2003 to February 2019, without language restrictions. We included randomized controlled trials (RCTs) comparing the effectiveness of self-management interventions with usual care or enhanced usual care in young adults. Outcomes of interest included clinical outcomes, psychological health, self-care behaviours, diabetes knowledge and self-efficacy. Pairwise meta-analysis was conducted using a random effects model and quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) criteria. We followed Cochrane gold standard systematic review methodology and reported this systematic review according to PRISMA guidelines. The protocol was registered with PROSEPRO (CRD42018110868).

RESULTS

In total, 13 studies (1002 participants) were included. Meta-analysis showed no difference between self-management interventions and controls in post-intervention HbA_1c levels, BMI, depression, diabetes-related distress, overall self-care, diabetes knowledge and self-efficacy. Quality of evidence ranged from very low to moderate due to study limitations, inconsistency and imprecision.

CONCLUSIONS

Current self-management interventions did not improve outcomes in young adults with diabetes. Our findings, which contrast with those from systematic reviews in older adults, highlight the need for the development of more effective interventions for young adults with diabetes.

The Microalbuminuria Education Medication and Optimisation (MEMO) study: 4 years follow-up of multifactorial intervention in high-risk individuals with type 2 diabetes

AIMS

The Microalbuminuria Education Medication and Optimisation (MEMO) study, revealed improved cardiovascular risk and glycaemic control with 18 months of intensive multifactorial intervention in high-risk people with type 2 diabetes, without any increase in severe hypoglycaemia. Our aim was to assess longer-term outcomes at 4-year follow-up in these participants.

METHODS

Some 189 individuals with type 2 diabetes and microalbuminuria were recruited from a multi-ethnic population in Leicestershire, UK. The intervention group (n = 95) received multifactorial intervention with self-management education, and the control group (n = 94) received usual care. The primary outcome was change in HbA_1c , and secondary outcomes were blood pressure (BP), cholesterol, microalbuminuria, estimated GFR, cardiovascular risk scores and major adverse cardiovascular events.

RESULTS

Some 130 participants (68.7%), mean (sd) age 60.8 (10.4) years, duration of diabetes 11.5 (9.7) years, completed 4 years of follow-up. Mean change [95% confidence intervals (CI)] in HbA_1c over 4 years was greater with intensive intervention compared with control (-3 mmol/mol, 95% CI -4.95,-1.11; -0.4%, 95% CI -0.67,-0.15; P = 0.002). Significant improvements over the 4 years were also seen in systolic BP (-7.3 mmHg, 95% CI -11.1, -3.5; P < 0.001), diastolic BP (-2.9 mmHg, 95% CI -5.4, -0.3; P = 0.026), cholesterol (-0.3 mmol/l, 95% CI -0.52,-0.12; P = 0.002), and 10-year coronary heart disease (-5.3, 95% CI -8.2,-2.3; P < 0.001) and stroke risk (-4.4, 95% CI -7.5, -1.3; P < 0.001).

CONCLUSION

Multifactorial intervention with structured diabetes self-management education compared with usual diabetes care has benefits for cardio-metabolic risk factor profile. There was no increase in severe hypoglycaemia and cardiovascular mortality despite intensive glycaemic control, although the study was not powered to assess these outcomes.

The effectiveness of patient activation intervention on type 2 diabetes mellitus glycemic control and self-management behaviors: A systematic review of RCTs

BACKGROUND

Type 2 diabetes mellitus T2DM is a major health challenge and associated with several complications and mortality. Self-management behaviors SMBs such as healthy diet, physical activity, blood glucose self-monitoring, foot care and medication adherence are critical part of diabetic care. Empowered or activated patients, are more likely to practice better SMBs. However, the effectiveness of patient activation intervention on T2DM glycemic control and SMBs is not totally well understood.

AIM

To assess the effectiveness of patient activation intervention on T2DM glycemic control and SMBs.

METHOD

A systematic search was undertaken through five databases to find relevant studies published between 2004 and 2018. We included randomized controlled trials with sample size ≥120 and follow up period of ≥12 months and assess the effectiveness of patient activation intervention on T2DM glycemic control and SMBs.

RESULTS

10 RCTs were identified for analysis. The total sample size is 3728 and the combined mean age is 57.3 years. The combined mean BMI is 31.2kg/m² (obese). Seven intervention demonstrated a significant reduction in HbA1c, ranged from 0.36 to 0.80%. All interventions presented an improvement in at least one self-management behavior.

DISCUSSION AND CONCLUSION

Patient activation intervention showed a significant positive effect on T2DM glycemic control and SMBs, particularly physical activity, healthy diet, foot care and blood glucose self-monitoring. The effectiveness on SMBs was seen across different intervention strategies, modes of delivery, length of intervention, and number of providers. Better effectiveness on HbA1c was associated with poorly controlled participants, culturally tailored-intervention, and in-person sessions intervention combined with telephone calls follow up.

An Effective Model of Diabetes Care and Education: Revising the AADE7 Self-Care Behaviors®

PURPOSE

The AADE7 Self-Care Behaviors^® (AADE7) is a robust framework for self-management of diabetes and other related conditions, such as prediabetes and cardiometabolic diseases. It is the position of the American Association of Diabetes Educators (AADE) that, at the cornerstone of diabetes self-management education and support, the AADE7 is the framework for achieving behavior change that leads to effective self-management through improved behavior and clinical outcome measures. The AADE7 model guides the health care team in effective person-centered collaboration and goal setting to achieve health-related outcomes and improved quality of life. Continued research and evidence are critical to expand this model and broaden its application to other chronic conditions. Given the advances in the science of diabetes management, as well as in diabetes self-management education and support, AADE has evaluated the AADE7 within the framework of these advances, including the digital and dynamic health care landscape.

CONCLUSION

This revised position statement blends the updates in research and AADE's vision and expansion beyond diabetes to refresh the AADE7 framework. This revision reflects the perspectives of all members of the health care team as they problem solve with individuals who are at risk for or who have diabetes and related conditions to achieve healthier outcomes.

Effectiveness of Diabetes Self-Management Educational Programs For Type 2 Diabetes Mellitus Patients In Middle East Countries: A Systematic Review

AIM

This review study aimed to determine the effectiveness and factors affecting the success of DSME programs in T2DM patients living in ME countries.

METHODS

An extensive manual literature search was conducted using PubMed and Google Scholar for clinical trials assessing the effect of diabetes self-management education (DSME) for type 2 diabetes mellitus patients in Middle East countries. Information from the included studies was summarized in relation to study population, sample size, duration of follow-up, characteristics of DSME program, and follow-up time, besides in addition to parameters used in assessment, results, and conclusions. The risk of bias in the included studies was assessed using the Cochrane risk of bias tool. The effect of DSME on clinical and patient-reported outcomes was measured by calculation of the percentage of DSME studies that produce a significant improvement in these outcomes for patients in intervention group as compared to those in control group. Additionally, the effect of DSME on each clinical outcome was assessed by calculating the mean for the absolute effect of DSME on that outcome.

RESULTS

Twelve studies were included in this review. Heterogeneity was found among included studies in terms of DSME program characteristics, the enrolled patients, duration of follow-up, assessment methods, and obtained outcomes. All clinical glycemic outcomes (glycosylated hemoglobin, fasting, and non-fasting blood glucose), lipid profile (total cholesterol and triglycerides), and body mass index were significantly improved for patients in intervention group as compared to those in control group in at least 60% of the included studies. All patients' reported outcomes (medication adherence, self-management behavior, knowledge, self-efficacy, health belief and quality of life) were significantly improved by the DSME program.

CONCLUSION

DSME programs are highly effective in improving glycemic control, lipid profile and BMI, and modestly effective in improving BP. Thus, they can reduce the risks of developing diabetes complications. Patient diabetes knowledge, DSM behaviors, adherence to medications, self-efficacy, and quality of life can also be significantly improved by DSME.

2017 National Standards for Diabetes Self-Management Education and Support

PURPOSE

The purpose of this study is to review the literature for Diabetes Self-Management Education and Support (DSMES) to ensure the National Standards for DSMES (Standards) align with current evidence-based practices and utilization trends.

METHODS

The 10 Standards were divided among 20 interdisciplinary workgroup members. Members searched the current research for diabetes education and support, behavioral health, clinical, health care environment, technical, reimbursement, and business practice for the strongest evidence that guided the Standards revision.

RESULTS

Diabetes Self-Management Education and Support facilitates the knowledge, skills, and ability necessary for diabetes self-care as well as activities that assist a person in implementing and sustaining the behaviors needed to manage their condition on an ongoing basis. The evidence indicates that health care providers and people affected by diabetes are embracing technology, and this is having a positive impact of DSMES access, utilization, and outcomes.

CONCLUSION

Quality DSMES continues to be a critical element of care for all people with diabetes. The DSMES services must be individualized and guided by the concerns, preferences, and needs of the person affected by diabetes. Even with the abundance of evidence supporting the benefits of DSMES, it continues to be underutilized, but as with other health care services, technology is changing the way DSMES is delivered and utilized with positive outcomes.

Improving type 2 diabetes mellitus glycaemic control through lifestyle modification implementing diet intervention: a systematic review and meta-analysis

PURPOSE

Type 2 diabetes mellitus represents a significant health problem. Many studies have reported that intensive nutritional intervention by itself or in addition to medications is the best method to improve glycaemic control in type 2 diabetes mellitus. However, in clinical practice, dietary education is not implemented as an integral part in the management of type 2 diabetes mellitus. The purpose of this systematic review and meta-analysis is to analyse the scientific evidence concerning the role of nutritional intervention in the glycaemic control of type 2 diabetes mellitus.

METHODS

We searched Pubmed, Scopus, Cochrane Library and Web of Science databases from inception till May 2019 for randomised controlled trials (RCTs) that include dietary interventions in the management of patients with type 2 diabetes mellitus.

RESULTS

A total of 28 studies were included. Our results demonstrated that lifestyle interventions significantly lowered glycosylated haemoglobin (HbA_1c) levels compared to the usual care for patients with type 2 diabetes mellitus, overall weighted mean difference, WMD = - 0.51 (- 0.67, - 0.35). Strategies combining individualized and group-based activities were the most effective, WMD = - 0.95 (- 1.24, - 0.66). Most of stratified analyses did not totally resolve heterogeneity, but improvement in HbA_1c levels has been consistently observed.

CONCLUSIONS

The available evidence from RCTs shows that lifestyle intervention is more effective than the standard care regarding the glycaemic control of type 2 diabetic patients, particularly when there is a weight loss. It is time to translate this evidence to the primary health care practice. The protocol of the present systematic review was registered in PROSPERO, registration number CRD42018090469.

TRIal to slow the Progression Of Diabetes (TRIPOD): study protocol for a randomized controlled trial using wireless technology and incentives

BACKGROUND

The outcomes for those with type 2 diabetes mellitus (T2DM) in Singapore are poor. In this TRIal to slow the Progression Of Diabetes (TRIPOD), we will evaluate the effectiveness and cost-effectiveness of a comprehensive diabetes management package (DMP), with or without a financial incentives program, M-POWER Rewards, in efforts to improve HbA1c levels for individuals with T2DM.

METHODS/DESIGN

TRIPOD is a randomized, open-label, controlled, multi-center, superiority trial with three parallel arms: (1) usual care only, (2) usual care with DMP, and (3) usual care with DMP plus M-POWER Rewards. A total of 339 adults with sub-optimally controlled T2DM (self-reported HbA1c 7.5-11.0%) will be block randomized according to a 1:1:1 allocation ratio to the three arms. The primary outcome is mean change in HbA1c level at Month 12 from baseline. Secondary outcomes include mean change in HbA1c level at Months 6, 18, and 24; mean changes at Months 6, 12, 18, and 24 in weight, blood pressure, and self-reported physical activity, weight monitoring, blood glucose monitoring, medication adherence, diabetes self-management, sleep quality, work productivity and daily activity impairment, and health utility index; and proportion of participants initiating insulin treatment by Months 6, 12, 18, and 24. Incremental cost-effectiveness ratios will be computed based on costs per improvement in HbA1c at Month 12 and converted to cost per quality-adjusted life year gained.

DISCUSSION

The TRIPOD study will present insights about the long-term cost-effectiveness and financial viability of the interventions and the potential for integrating within usual care.

The impact of an intervention to increase uptake to structured self-management education for people with type 2 diabetes mellitus in primary care (the embedding package), compared to usual care, on glycaemic control: study protocol for a mixed methods study incorporating a wait-list cluster randomised controlled trial

BACKGROUND

Approximately 425 million people globally have diabetes, with ~ 90% of these having Type 2 Diabetes Mellitus (T2DM). This is a condition that leads to a poor quality of life and increased risk of serious health complications. Structured self-management education (SSME) has been shown to be effective in improving glycaemic control and patient related outcome measures and to be cost-effective. However, despite the demonstrated benefits, attendance at SSME remains low. An intervention has been developed to embed SSME called the 'Embedding Package'. The intervention aims to address barriers and enhance enablers to uptake of SSME at patient, healthcare professional and organisational levels. It comprises a marketing strategy, user friendly and effective referral pathways, new roles to champion SSME and a toolkit of resources.

METHODS

A mixed methods study incorporating a wait-list cluster randomised trial and ethnographic study, including 66 UK general practices, will be conducted with two intervention start times (at 0 and 9 months), each followed by an active delivery phase. At 18 months, the intervention will cease to be actively delivered and a 12 month observational follow-up phase will begin. The intervention, the Embedding Package, aims to increase SSME uptake and subsequent improvements in health outcomes, through a clear marketing strategy, user friendly and effective referral pathways, a local clinical champion and an 'Embedder' and a toolkit of resources for patients, healthcare professionals and other key stakeholders. The primary aim is, through increasing uptake to and attendance at SSME, to reduce HbA1c in people with T2DM compared with usual care. Secondary objectives include: assessing whether there is an increase in referral to and uptake of SSME and improvements in biomedical and psychosocial outcomes; an assessment of the sustainability of the Embedding Package; contextualising the process of implementation, sustainability of change and the 'fit' of the Embedding Package; and an assessment of the cost-effectiveness of the Embedding Package.

DISCUSSION

This study will assess the effectiveness, cost-effectiveness and sustainability of the Embedding Package, an intervention which aims to improve biomedical and psychosocial outcomes of people with T2DM, through increased referral to and uptake of SSME.

TRIAL REGISTRATION

International Standard Randomised Controlled Trials Number ISRCTN23474120. Assigned 05/04/2018. The study was prospectively registered. On submission of this manuscript practice recruitment is complete, participant recruitment is ongoing and expected to be completed by the end of 2019.

A systematic review of diabetes self-management education interventions for people with type 2 diabetes mellitus in the Asian Western Pacific (AWP) region

AIMS AND OBJECTIVES

To assess the effectiveness of educational and/or psychological diabetes self-management education (DSME) intervention for people with type 2 diabetes (T2DM) in the Asian Western Pacific (AWP) region.

BACKGROUND

Translational research indicates that DSME is effective; therefore, it is important to look at the AWP region to see what has been implemented and what the potential barriers are for the low integration of DSME. The need for DSME is present, and programmes are being developed. Therefore, focusing a systematic review of DSME research in the AWP region would give a better understanding of which intervention approaches are associated with better clinical outcomes and are culturally acceptable.

DESIGN

A systematic review.

METHODS

A review of randomized controlled trials (RCTs) and comparative studies to evaluate the effectiveness of face-to-face delivery reporting educational and/or psychological interventions for people with T2DM was implemented. We conducted searches using MEDLINE, EMBASE, CINAHL, PubMed and ASSIA databases between January 1990-June 2018. Studies published in English and non-English were included. Two reviewers independently extracted data on participant and intervention characteristics. The quality of evidence was rated on predetermined criteria. Main outcomes included glycaemic control (reduction in HbA1c level).

RESULTS

We included 21 DSME programmes (17 RCTs), while 15 were group-based approaches. Twelve studies (60%) were categorized as high quality. Three studies (25%) had a moderate (good) effect. Eight trials were effective in improving glycaemic control and reported statistically significant improvements in HbA1c levels. 50% of these were high-intensity group-based programmes.

Learning types and learning success in a structured diabetes education programme for patients with type 2 diabetes: study protocol of a prospective, longitudinal study

INTRODUCTION

Diabetes mellitus (DM) has had a wide-ranging impact on healthcare politics. Secondary diseases and complications caused by diabetes are relevant cost and utilisation factors in the healthcare system. For decades, diabetes self-management education (DSME) has played a major role in the treatment of patients with type 2 DM (T2DM). The aim of this training is to empower patients to actively influence their diabetes process by gaining knowledge about health-related behaviours, such as healthy nutrition and exercise, and cardiovascular risks. The aim of the project is to analyse the practice of structured diabetes education and the effects of different learning types of participants. This project focuses on the needs of socioeconomically deprived patients and aims to improve DSME for this group. This patient group has a higher prevalence of T2DM, more complications and worse therapy-relevant parameters.

METHODS AND ANALYSIS

The study will be conducted as a prospective longitudinal study. Patients will be recruited in outpatient physician offices over a period of 12 months. Patients will be included if they are 18 years and older, have T2DM and are scheduled to participate in DSME for the first time. A pseudonymised, written survey with standardised questionnaires will be administered. The data will be analysed using inferential statistical methods, such as correlation analysis, regression models and variance analytical designs.

ETHICS AND DISSEMINATION

The study will be carried out following the principles of the Declaration of Helsinki and good scientific standards. Ethical approval of the Ethics Review Committee of the Medical Faculty at Martin-Luther-University, Halle-Wittenberg, was obtained. All participants in the study will receive comprehensive information and will be included after written informed consent is obtained. The results will be published in international peer-reviewed journals and presented at several congresses.

A Diabetes Education Model in Primary Care: Provider and Staff Perspectives

Purpose

The purpose of this qualitative study was to explore the effectiveness of Glucose to Goal (G2G), a diabetes self-management education and support (DSMES) model for primary care (PC).

Methods

PC providers and staff were recruited from 5 PC practices participating in the 18-month intervention to participate in focus groups and interviews, which were used to gain insights about their perspectives on DSMES and how G2G was implemented across the intervention. Data were collected by qualitative researchers at baseline, midpoint, and study completion.

Results

At baseline, PC participants held a favorable view of DSMES and welcomed having a diabetes educator (DE) in their practice. Most participants suggested DEs would be helpful in meeting patients’ nutrition needs but should give therapeutic advice only with a doctor’s oversight. Participants anticipated that having a DE onsite would mitigate transportation, scheduling, communication, and cost barriers. Participant viewpoints about G2G remained unchanged from midpoint to study end, while barriers regarding location and transportation were perceived as being reduced by having a DE in the practice. Despite referral rates remaining low in some practices, many concerns stated at earlier timepoints appeared to have been attenuated by G2G components (eg, bringing the DE onsite, preidentifying patients, and DE ability to communicate and make diabetes management recommendations).

Conclusions

This study demonstrates that G2G, providing DSMES in PC, appeared to be a welcome service where acceptance of and enthusiasm for the model grew over the course of the intervention.

Lay Advisor Interventions in Rural Populations: A Systematic Review and Meta-analysis

CONTEXT

Age-adjusted death rates for heart disease are higher in rural areas than in urban areas. Lay advisors could potentially facilitate improvement in cardiovascular health outcomes. The aim of this systematic review and meta-analysis is to estimate lay advisor intervention effects on cardiovascular health metrics in rural populations.

EVIDENCE ACQUISITION

Searches of databases including MEDLINE, CINAHL, and Scopus from 1975 through October 2017 retrieved 323 citations, of which 272 abstracts were reviewed. Two authors independently abstracted data from eligible studies. Analysis was conducted in March 2018.

EVIDENCE SYNTHESIS

Of 21 articles included in the systematic review, eight were RCTs and 13 were pre- and post-intervention studies. Of the RCTs, three took place in the U.S. Only two studies had low risk of bias. Using a random effects model, meta-analysis of six RCTs (1,641 participants) showed that lay advisor interventions in rural residents were associated with improvement in HbA1c of 0.4% (95% CI=0.13, 0.66, p=0.004, I²=60.65%). From four RCTs (873 participants), lay advisor interventions significantly improved BMI with pooled effect of 2.18 (95% CI=1.13, 3.24, p<0.001, I²=0.00%). Most studies had normal baseline blood pressure and cholesterol levels before intervention, and no significant effects were noted for these outcomes. Diverse types of measures used for diet, physical activity, and smoking precluded statistical synthesis.

CONCLUSIONS

Lay advisor interventions had significant positive effects on glycemic control and BMI for rural residents; however, further rigorous studies are needed in U.S. rural populations, and elements of effective lay advisor interventions require further investigation.

Randomized Trial of a Lifestyle Intervention for Urban Low-Income African Americans with Type 2 Diabetes

BACKGROUND

African Americans suffer more than non-Hispanic whites from type 2 diabetes, but diabetes self-management education (DSME) has been less effective at improving glycemic control for African Americans. Our objective was to determine whether a novel, culturally tailored DSME intervention would result in sustained improvements in glycemic control in low-income African-American patients of public hospital clinics.

RESEARCH DESIGN AND METHODS

This randomized controlled trial (n = 211) compared changes in hemoglobin A1c (A1c) at 6, 12, and 18 months between two arms: (1) Lifestyle Improvement through Food and Exercise (LIFE), a culturally tailored, 28-session community-based intervention, focused on diet and physical activity, and (2) a standard of care comparison group receiving two group DSME classes. Cluster-adjusted ANCOVA modeling was used to assess A1c changes from baseline to 6, 12, and 18 months, respectively, between arms.

RESULTS

At 6 months, A1c decreased significantly more in the intervention group than the control group (- 0.76 vs - 0.21%, p = 0.03). However, by 12 and 18 months, the difference was no longer significant (12 months - 0.63 intervention vs - 0.45 control, p = 0.52). There was a decrease in A1c over 18 months in both the intervention (β = - 0.026, p = 0.003) and the comparison arm (β = - 0.018, p = 0.048) but no difference in trend (p = 0.472) between arms. The intervention group had greater improvements in nutrition knowledge (11.1 vs 6.0 point change, p = 0.002) and diet quality (4.0 vs - 0.5 point change, p = 0.018) while the comparison group had more participants with improved medication adherence (24% vs 10%, p < 0.05) at 12 months.

CONCLUSIONS

The LIFE intervention resulted in improved nutrition knowledge and diet quality and the comparison intervention resulted in improved medication adherence. LIFE participants showed greater A1c reduction than standard of care at 6 months but the difference between groups was no longer significant at 12 and 18 months.

Care management intervention to strengthen self-care of multimorbid patients with type 2 diabetes in a German primary care network: A randomized controlled trial

Purpose

This study aimed to assess the effectiveness of a care management intervention in improving self-management behavior in multimorbid patients with type 2 diabetes; care was delivered by medical assistants in the context of a primary care network (PCN) in Germany.

Methods

This study is an 18-month, multi-center, two-armed, open-label, patient-randomized parallel-group superiority trial (ISRCTN 83908315). The intervention group received the care management intervention in addition to the usual care. The control group received usual care only. The primary outcome was the change in self-care behavior at month 9 compared to baseline. The self-care behavior was measured with the German version of the Summary of Diabetes Self-Care Activities Measure (SDSCA-G). A multilevel regression analysis was applied.

Results

We assigned 495 patients to intervention (n = 252) and control (n = 243). At baseline, the mean age was 68 ±11 years, 47.8% of the patients were female and the mean HbA1c was 7.1±1.2%. The primary analysis showed no statistically significant effect, but a positive trend was observed (p = 0.206; 95%-CI = -0.084; 0.384). The descriptive analysis revealed a significantly increased sum score of the SDSCA-G in the intervention group over time (P = 0.012) but not in the control group (p = 0.1973).

Conclusion

The sum score for self-care behavior markedly improved in the intervention group over time. However, the results of our primary analysis showed no statistically significant effect.

Possible reasons are the high baseline performance in our sample and the low intervention fidelity. The implementation of this care management intervention in PCNs has the potential to improve self-care behavior of multimorbid patients with type 2 diabetes.

A Mobile Lifestyle Management Program (GlycoLeap) for People With Type 2 Diabetes: Single-Arm Feasibility Study

Background

Singapore’s current prevalence of diabetes exceeds 13.6%. Although lifestyle modification can be effective for reducing the risks for complications of type 2 diabetes mellitus (T2DM), traditional lifestyle interventions are often difficult to administer in the primary care setting due to limited resources. Mobile health apps can address these limitations by offering low-cost, adaptable, and accessible platforms for disseminating lifestyle management interventions.

Objective

Using the RE-AIM evaluation framework, this study assessed the potential effectiveness and feasibility of GlycoLeap, a mobile lifestyle management program for people with T2DM, as an add-on to standard care.

Methods

This single-arm feasibility study recruited 100 patients with T2DM and glycated hemoglobin (HbA_1c) levels of ≥7.5% from a single community health care facility in Singapore. All participants were given access to a 6-month mobile lifestyle management program, GlycoLeap, comprising online lessons and the Glyco mobile phone app with a health coaching feature. The GlycoLeap program was evaluated using 4 relevant dimensions of the RE-AIM framework: (1) reach (percentage who consented to participate out of all patients approached), (2) effectiveness (percentage point change in HbA_1c [primary outcome] and weight loss [secondary outcome]), (3) implementation (program engagement as assessed by various participatory metrics), and (4) maintenance (postintervention user satisfaction surveys to predict the sustainability of GlycoLeap). Participants were assessed at baseline and at follow-up (≥12 weeks after starting the intervention).

Results

A total of 785 patients were approached of whom 104 consented to participate, placing the reach at 13.2%. Four were excluded after eligibility screening, and 100 patients were recruited. Program engagement (implementation) started out high but decreased with time for all evaluated components. Self-reported survey data suggest that participants monitored their blood glucose on more days in the past week at follow-up compared to baseline (P<.001) and reported positive changes to their diet due to app engagement (P<.001) (implementation). Primary outcome data were available for 83 participants. Statistically significant improvements were observed for HbA_1c (–1.3 percentage points, P<.001) with greater improvements for those who logged their weight more often (P=.007) (effectiveness). Participants also had a 2.3% reduction in baseline weight (P<.001) (effectiveness). User satisfaction was high with 74% (59/80) and 79% (63/80) of participants rating the app good or very good and claiming that they would probably or definitely recommend the app to others, respectively (maintenance).

Conclusions

Although measures of program engagement decreased with time, clinically significant improvements in HbA_1c were achieved with the potential for broader implementation. However, we cannot rule out that these improvements were due to factors unrelated to GlycoLeap. Therefore, we would recommend evaluating the effectiveness and cost effectiveness of GlycoLeap using a randomized controlled trial of at least 12 months.

Identification of Education Models to Improve Health Outcomes in Arab Women with Pre-Diabetes

Few evaluations of interventions to delay or prevent type 2 diabetes mellitus (T2DM) in Saudi Arabia (SA) have been undertaken. The present study evaluates the impact of a 6-month intensive lifestyle modification intervention delivered in primary care. Females from SA with prediabetes, aged 18–55 years, were recruited with 190 participants eligible following screening and randomly allocated to receive a 3-month one-on-one, intensive lifestyle modification (intervention group (IG) n = 95) or standard guidance (control group (CG) n = 95). Participants completed questionnaires including demographic, dietary and physical activity data. Blood samples were collected at baseline, 3 and 6 months. A total of 123 (74 IG (age 40.6 ± 9.8 years; body mass index (BMI) 31.2 ± 7.0 kg/m²) and 49 CG (age 40.6 ± 12.7 years; BMI 32.3 ± 5.4 kg/m²)) participants completed the study. After 6 months, haemoglobin A1c (HbA1c; primary endpoint) significantly improved in the IG than CG completers in between-group comparisons (p < 0.001). Comparison between groups showed significant improvements in overall energy intake, total and high density lipoprotein (HDL)-cholesterol in favour of IG (p-values < 0.001, 0.04 and <0.001, respectively). BMI and weight change were not clinically significant in between group comparisons. A 6-month, intense one-on-one intervention in lifestyle modification significantly improves glycaemic and cardio metabolic profile of females living in SA with pre-diabetes delivered in a primary care setting. Longer duration studies, using the same intervention, may determine whether a meaningful weight loss secondary to improved diet can be achieved.
