Translational research for Diabetes Self-Management in Sri Lanka: A randomized controlled trial

The effectiveness of diabetes self-management education intervention on glycaemic control and cardiometabolic risk in adults with type 2 diabetes in low- and middle-income countries: A systematic review and meta-analysis

Diabetes mellitus (DM) poses a significant challenge to public health. Effective diabetes self-management education (DSME) interventions may play a pivotal role in the care of people with type 2 diabetes mellitus (T2DM) in low- and middle-income countries (LMICs). A specific up-to-date systematic review is needed to assess the effect of DSME interventions on glycaemic control, cardiometabolic risk, self-management behaviours, and psychosocial well-being among T2DM across LMICs. The MEDLINE, Embase, CINAHL, Global Health, and Cochrane databases were searched on 02 August 2022 and then updated on 10 November 2023 for published randomised controlled trials (RCTs) and quasi-experimental studies. The quality of the studies was assessed, and a random-effect model was used to estimate the pooled effect of diabetes DSME intervention. Heterogeneity (I2) was tested, and subgroup analyses were performed. Egger's regression test and funnel plots were used to examine publication bias. The risk of bias of the included studies was assessed using the Cochrane risk-of-bias tool for randomized trial (RoB 2). The overall assessment of the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation approach. A total of 5893 articles were retrieved, and 44 studies (n = 11838) from 21 LMICs met the inclusion criteria. Compared with standard care, pooled analysis showed that DSME effectively reduced the HbA1c level by 0.64% (95% CI: 0.45% to 0.83%) and 1.27% (95% CI: -0.63% to 3.17%) for RCTs and quasi-experimental design studies, respectively. Further, the findings showed an improvement in cardiometabolic risk reduction, diabetes self-management behaviours, and psychosocial well-being. This review suggests that ongoing support alongside individualised face-to-face intervention delivery is favourable for improving overall T2DM management in LMICs, with a special emphasis on countries in the lowest income group.

The effect of self-management intervention among type 2 diabetes: A systematic review and meta-analysis

BACKGROUND

Using self-management interventions in type 2 diabetes care helps to regulate blood sugar levels, reduce caregiver burden, improve health outcomes, and improve expense management. Despite these benefits, the efficacy of self-management interventions for type 2 diabetes care remains uncertain, with studies showing inconclusive results that are open to interpretation.

AIMS

The aim of this systematic review and meta-analysis was to examine the available data to determine the effectiveness of self-management strategies for individuals with type 2 diabetes.

METHODS

The search method was restricted to the Cumulative Index to Nursing and Allied Health Literature, PubMed, ProQuest, Science Direct, and Scopus from January 2012 to December 2022. SPSS version 28 was used for the meta-analysis.

RESULTS

Seven studies fulfilled the eligibility criteria, with 697 individuals with type 2 diabetes included. Six papers were designed as randomized control trials and one as a quasi-experimental study. Meta-analysis showed a significant difference between the self-management and control groups, with a standardized mean difference (Cohen's d) of -0.40, (95% confidence interval [-0.60 to -0.20]), p = .00.

LINKING EVIDENCE TO ACTION

This meta-analysis showed that self-management interventions in type 2 diabetes patients successfully reduced HbA1c. Self-management improves type 2 diabetes treatment by helping people stay healthy and adapt to their illnesses.

The effectiveness of self-management programme based on multilevel social resources utilization in diabetes mellitus patients: A randomized controlled study

AIMS

This study aimed to test the effects of a novel diabetes self-management education (DSME) programme focused on multilevel social resources utilization on improving self-management behaviour, social resources utilization and haemoglobin A_lc (HbA_1c ) in patients with type 2 diabetes mellitus (T2DM).

METHODS

A randomized controlled design was used. A total of 118 participants with T2DM from two communities were recruited through randomized sampling, and randomly assigned to the novel DSME group or the traditional DSME group. DSME focusing on multilevel social resources utilization was implemented in the novel DSME group. Data were collected at baseline (T₀ ), at the end of the intervention (T₁ ) and 3 months after the end of intervention (T₂ ) from 3 March to 16 November 2014.

RESULTS

Comparing these two groups, the participants in the novel DSME group reported significantly better improvement in self-management behaviour and social resources utilization at T₁ and T₂ (all p < 0.01). A significant difference was found in the mean improvement of HbA_1c level between the two groups at T₂ (p < 0.05).

CONCLUSIONS

The novel DSME programme focused on multilevel social resources utilization can effectively enhance T2DM patients' self-management behaviour and social resource utilization and lower HbA_1c levels. More importantly, the effects could last longer.

Potential Methods to Improve Self-management in Those with Type 2 Diabetes: A Narrative Review

CONTEXT

The ability of self-manage was important for type 2 diabetes mellitus (T2DM) patients and it was supported and depend on the method used. We aimed to summarize the potential method of self-management to improve self-empowerment.

EVIDENCE ACQUISITION

To obtain the related data, 5 databases, including Scopus, Science Direct, ProQuest, CINAHL, and SAGE, were comprehensively searched. The search was done in advance using the Boolean operator. The full texts of articles presenting data on self-management methods were screened and retrieved.

RESULTS

A total of 22 studies were included in this review. Various self-management techniques were covered with primary and secondary outcomes. Primary outcomes included blood pressure, fasting blood glucose (FBG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL). Secondary outcomes included knowledge, self-efficacy, lifestyle habits, physical activity, diet, smoking, medical treatment, support, and health behavior. A goal-setting-oriented approach was effective in setting targets and gaining support from family members. A family-centered approach was effective in taking care of and taking good care of patients with T2DM. Strength training exercises provide patients with a choice of physical activity that can help them manage their blood sugar and blood pressure. Acceptance and commitment therapy (ACT) is a stress-reduction technique. The patient's acceptance of the disease and treatment for diabetes is aided by education.

CONCLUSIONS

A successful self-management method was one which balances and adapts to the patient's condition. Regardless of the age of the patients, the overall findings from the review suggest that self-management methods can help patients become healthier and improve their quality of life by controlling their hemoglobin A1c (HbA1c) level.

Dietary Management Tools Improve the Dietary Skills of Patients with T2DM in Communities

Dietary management is of paramount importance in the prevention and control of type 2 diabetes mellitus (T2DM). This one-year cluster-randomized controlled trial aims to evaluate the effect of dietary management tools on the dietary skills of patients with T2DM. Twenty-two communities were randomly assigned to an intervention group and a control group, and participants in the intervention group received a food guiding booklet (G) and a dinner set (D). The frequency of dietary management tools usage was collected at baseline and every three months, and different use patterns were identified by a group-based trajectory model. A self-compiled diabetic dietary skills scale and blood glucose were collected at baseline, 3, and 12 months, and a using generalized linear mixed model (GLMM) to explore the influence factors of dietary skills and blood glucose. The finding revealed four dietary tool-usage patterns among the participants: Insist using G/D, Give up gradually G/D, Give up after use G, and Never use G/D. GLMM indicated that dietary skills were higher over time (p < 0.05), and in participants using the guiding booklet (p < 0.001) or dinner set (p < 0.001), or with higher education (p < 0.001). Additionally, blood glucose were lower among participants with higher dietary skills (p = 0.003), higher educational level (p = 0.046), and a 3000−5000 monthly income (p = 0.026). These findings support using food management tools like the guiding booklet and dinner set as a useful strategy in primary health care centers for individuals with T2DM to increase their dietary skills and blood glucose control.

Determining the frequency and level of task-sharing for hypertension management in LMICs: A systematic review and meta-analysis

BACKGROUND

Low- and middle-income countries (LMICs) bear a disproportionately higher burden of Cardiovascular Disease (CVD). Team-based care approach adds capacity to improve blood pressure (BP) control. This updated review aimed to test team-based care efficacy at different levels of hypertension team-based care complexity.

METHODS

We searched PubMed, Embase, Cochrane, and CINAHL for newer articles on task-sharing interventions to manage hypertension in LMICs. Levels of tasks complexity performed by healthcare workers added to the clinical team in hypertension control programs were categorized as administrative tasks (level 1), basic clinical tasks (level 2), and/or advanced clinical tasks (level 3). Meta-analysis using an inverse variance weighted random-effects model summarized trial-based evidence on the efficacy of team-based care on BP control, compared with usual care.

FINDINGS

Forty-three RCT articles were included in the meta-analysis: 31 studies from the previous systematic review, 12 articles from the updated search. The pooled mean effect for team-based care was a -4.6 mm Hg (95% CI: -5.8, -3.4, I²  = 80.2%) decrease in systolic BP compared with usual care. We found similar comparative reduction among different levels of team-based care complexity, i.e., administrative and basic clinical tasks (-4.7 mm Hg, 95% CI: -6.8, -2.2; I²  = 79.8%); and advanced clinical tasks (-4.5 mmHg, 95%CI: -6.1, -3.3; I²  = 81%). Systolic BP was reduced most by team-based care involving pharmacists (-7.3 mm Hg, 95% CI: -9.2, -5.4; I²  = 67.2%); followed by nurses (-5.1 mm Hg, 95% CI: -8.0, -2.2; I²  = 72.7%), dieticians (-4.7 mmHg, 95%CI: -7.1, -2.3; I²  = 0.0%), then community health workers (-3.3 mm Hg, 95% CI: -4.8, -1.8; I²  = 77.3%).

INTERPRETATION

Overall, team-based hypertension care interventions consistently contributed to lower systolic BP compared to usual care; the effect size varies by the clinical training of the healthcare team members.

Individual goal-based plan based on nursing theory for adults with type 2 diabetes and self-care deficits: a study protocol of a randomised controlled trial

INTRODUCTION

The prevalence and costs of type 2 diabetes are increasing worldwide. A cornerstone in the treatment and care of diabetes is supporting each patient in self-management. In Sweden, most patients with type 2 diabetes are cared for in the primary care setting, which is heavily burdened. Because of implementation difficulties regarding evidenced-based diabetes self-management education and support in this setting, there is a need for an instrument that is easy to use and implement. We developed an individual care plan based on the self-care deficit nursing theory of Dorothea Orem as an instrument to facilitate more individualised self-care support for patients with type 2 diabetes. In this study, we aim to determine whether a written, theory-based, individual goal-based plan for patients with type 2 diabetes and self-management deficits can affect their glycaemic control and health-related quality of life, as well as their experiences of living with diabetes and of support from diabetes care.

METHODS AND ANALYSIS

The study design is a randomised controlled trial using a quantitative approach. A total of 110 patients will be included. Additionally, a qualitative interview study will be conducted 12 months after the intervention. The primary outcome will be glycosylated haemoglobin levels. Secondary outcomes will be health-related quality of life measured using the RAND-36, and the patient's experience of living with diabetes and of the support from diabetes care measured using the Diabetes Questionnaire. Quantitative data will be analysed using the paired t-test, unpaired t-test, and Mann-Whitney U test with IBM SPSS V.26.0 software. Qualitative content analysis will be used for qualitative data.

ETHICS AND DISSEMINATION

This study has been approved by the Ethical Review Authority in Uppsala, Sweden (Etikprövningsmyndigheten, Uppsala, Sverige) (Dnr: 2020-03421). The results will be disseminated in peer-reviewed publications.

Nurse-led care versus usual care on cardiovascular risk factors for patients with type 2 diabetes: a systematic review and meta-analysis

OBJECTS

This study aims to systematically evaluate the effectiveness of nurse-led cares on cardiovascular risk factors among individuals with type 2 diabetes mellitus.

DESIGN

Systematic review and meta-analysis.

METHODS

The electronic databases PubMed, EMBASE, CINAHL and Cochrane Library databases were searched for randomised controlled trials of nurse-led care for individuals with type 2 diabetes mellitus (T2DM) published in English from inception to 23 December 2021. Random effects models were used to calculate weighted mean differences (WMD) with 95%CI.

RESULTS

13 articles were included in the meta-analysis, with a total of3757 participants. Considering baseline measurements, pooled analysis showed that nurse-led care significantly decreased the glycosylated haemoglobin (HbA1c) (WMD=-0.68 mmol/L; 95% CI -0.85 to -0.52; p<0.001), body mass index (BMI) (WMD=-0.54 kg/m²; 95% CI: -0.97 to -0.11; p=0.01) and systolic blood pressure (SBP) (WMD=-1.17 mmHg; 95% CI: -2.11 to -0.22; p=0.02) for patients with T2DM. But there was no difference in low-density lipoprotein cholesterol (LDL-c) (WMD=-2.50 mg/dL ; 95% CI: -5.07 to 0.08; p=0.06) between the nurse-led and control groups.

CONCLUSION

Nurse-led care is an effective and accessible intervention that could improve HbA1c, SBP, BMI levels among individuals with T2DM.

Effect of educational interventions on knowledge of the disease and glycaemic control in patients with type 2 diabetes mellitus: a systematic review and meta-analysis of randomised controlled trials

BACKGROUND

Globally, type 2 diabetes has continued to increase, now accounting for over 90% of all diabetes cases. Though the magnitude of uncontrolled glycaemic levels in patients with type 2 diabetes is steadily rising, evidence showed that effectively controlled glycaemic levels can prevent complications and improve the quality of life of these patients. As little is known about the effect of educational interventions on this population, this systematic review and meta-analysis evaluated the effectiveness of educational interventions versus standard care on glycaemic control and disease knowledge among patients with type 2 diabetes.

METHODS

PubMed, Google Scholar, Cochrane Library, Scopus, African Journals Online and Wiley Online Library were searched. Two authors independently assessed within-trial risk of bias in each included study using revised Cochrane risk-of-bias tool for randomised trials. A random-effects model was employed to estimate combined effect sizes. Subgroup analyses were employed to investigate possible sources of heterogeneity between studies. The overall certainty of the evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation approach.

RESULTS

A total of 19 trials with 2708 study participants were included in the review. Primary outcomes (glycaemic control) were reported in 18 trials. The pooled estimated impact of educational intervention on glycaemic levels using the random-effects model was -0.83 (95% CI: -1.17 to -0.49, p<0.001). Subgroup analyses revealed greater A1c reductions in those studies with intervention duration of up to 3 months and with empirical intervention designs. Educational interventions led to significant increases in participants' knowledge of type 2 diabetes (standardised mean difference: 1.16; 95% CI: 0.71 to 1.60; I2=93%).

CONCLUSION

In the current review overall, educational interventions can potentially lead to improved glycaemic control levels in patients with type 2 diabetes despite heterogeneity across the studies. Besides, the findings showed that educational interventions could increase disease knowledge among patients with type 2 diabetes.

The Effects of Dietary Education Interventions on Individuals with Type 2 Diabetes: A Systematic Review and Meta-Analysis

As the incidence and prevalence of diabetes increases, intervention through dietary education is becoming more important for diabetes control. This systematic review examines the evidence for the efficacy of dietary education interventions on diabetes control. The study subjects were patients with type 2 diabetes, and the main outcome variable was glycosylated hemoglobin level (HbA1c). The target studies were randomized controlled trials. Thirty-six studies were included in the analysis, of which 33 were included in the meta-analysis. The effect size between dietary education and general interventions was -0.42 (n = 5639, MD = -0.42; 95% CI -0.53 to -0.31) and was significantly different (Z = 7.73, p < 0.001). When subgroup analyses were performed following the application periods, intervention methods, and intervention contents, the mean differences in 4-6-month application, individual education, and diet-exercise-psychosocial intervention were -0.51, (n = 2742, 95% CI -0.71 to -0.32), -0.63 (n = 627, 95% CI -1.00 to -0.26), and -0.51 (n = 3244, 95% CI -0.71 to -0.32), respectively. Dietary education interventions provided for at least 3 months were highly effective in controlling HbA1c levels. Regarding the education method, individualized education was more effective, and contact or non-contact education may be applied for this. Combining diet, exercise, and psychosocial intervention is more effective than diet education alone.

Motiva.DM2 project. A pilot behavioral intervention on diet and exercise for individuals with type 2 diabetes mellitus

AIM

The purpose of this study was to assess the efficacy of an educational intervention based on the Behavior Change Wheel (BCW) framework for individuals with type 2 diabetes mellitus (DM2) on dietary and exercise behavior in a Spanish region.

METHODS

A two-arm pilot research was developed. The intervention consisted of a 6-month period with guidelines and 4 in-person interventions. The outcome was changes in behaviors, motivation, competence, autonomy, social support to implement the recommendations, HbA1c, and body composition.

RESULTS

n = 111 patients were recruited. Individuals in the intervention experienced a significative improvement on adherence to dietary recommendations (+1.23; p = 0.026), exercise (+0.86; p = 0.001), and a decrease in HbA1c levels (-0.6%; p = 0.002) and BMI (-0.73; p < 0.001).

CONCLUSION

The intervention for DM2 individuals, based on the BCW framework, developed, and implemented by primary care nurses has been effective in improving the adherence to healthy eating, exercise, HbA1c levels, and body composition.

Task-sharing interventions for improving control of diabetes in low-income and middle-income countries: a systematic review and meta-analysis

Background

Task-sharing interventions using non-physician health-care workers might be a potential diabetes management strategy in health systems that are constrained by physician shortages, such as those in low-income and middle-income countries (LMICs).

Methods

We did a systematic review and meta-analysis of task-sharing intervention strategies for managing type 2 diabetes in LMICs. We searched PubMed, Embase, and CINAHL from database inception to Sept 25, 2019, for studies that were randomised control trials or cluster randomised trials with task-shifted or task-shared interventions delivered to adults (≥18 years) by non-physician health workers versus usual care, done in LMICs with glycated haemoglobin (HbA_1c) or fasting blood sugar (FBS) as outcome measures. The methodological quality of included studies was assessed using the Cochrane risk of bias tool. Random-effects model meta-analysis was used to estimate the population average pooled mean difference for HbA_1c and FBS with 95% CIs. Our study protocol was registered in the PROSPERO database (CRD42018081015).

Findings

We found 4213 studies from the literature search, of which 46 (1·1%) were eligible for the narrative synthesis, including a total of 16 973 participants. 16 of these studies were excluded from the meta-analysis due to high risk of bias. 24 studies with a total of 5345 participants were included in the meta-analysis of HbA_1c and 18 studies with a total of 3287 participants for FBS. Interventions led to an average reduction in HbA_1c when tasks were delivered by nurses (averaged pooled mean difference −0·54% [95% CI −0·89 to −0·18]; I²=80%) and pharmacists (−0·91% [–1·15 to −0·68]; I²=58%), but not when they were delivered by dietitians (−0·50% [–1·10 to 0·09]; I²=54%) or community health workers (0·05% [0·03 to 0·07]; I²=0%). A reduction in average FBS was also observed when interventions were delivered by pharmacists (average pooled mean difference −36·26 mg/dL [–52·60 to −19·92]; I²=78%) but not nurses (−7·46 mg/dL [–18·44 to 3·52]; I²=79%) or community health workers (−5·41 [–12·74 to 1·92]; I²=71%). Only one study reported on FBS when tasks were delivered by dietitians, with a mean difference of −35·00 mg/dL (−65·96 to −4·04).

Interpretation

Task sharing interventions with non-physician healthcare workers show moderate effectiveness in diabetes management in LMIC settings. Although relatively high heterogeneity limits the interpretation of the overall findings, interventions led by pharmacists and nurses in LMICs with relatively high physician density are effective strategies in the management of diabetes.

Effectiveness of theory-based diabetes self-care training interventions; a systematic review

BACKGROUND

Permanent compliance of self-care behaviors is a challenging issue in managing chronic diseases like diabetes. The evidence supports theory-based intervention in promoting self-care behaviors. However, no systematic review was done to monitor these interventions and compare more effective constructs. This study was conducted to investigate the studies using self-care theories and introducing the most effective theories.

METHODS

This is a systematic review study during which some scientific databases including Scopus, Elsevier, Google scholar and PubMed were searched by using some key words like self-care or self-management, diabetes, theory or model. English articles from the start of 2013 up to the end of November 2020 were monitored.

RESULTS

20 articles were selected and studied based on eight theories which they used. These theories were: Social support theory, Health Belief Model, Heath Belief Model and Empowerment Theory, Empowerment Theory, Self-efficacy Theory, precede-proceed model, Self-regulation Theory, behavioral theory and Social Cognitive Theory.

CONCLUSION

Four theories appeared to be more effective for the target behavior of present research: Social Support Theory and the combination of Empowerment Theory and Health Belief Model, Social Cognitive Theory and Self Efficacy Theory. Taken together, the findings of this systematic review suggest that interventions that go beyond individual determinants (such as changing knowledge and attitudes) to determinants of upper cognitive, motor, and social levels (such as the development of skills and competencies) they have led to raised self-care outcomes.

Exercise-based rehabilitation for major non-communicable diseases in low-resource settings: a scoping review

INTRODUCTION

While there is substantial evidence for the benefits of exercise-based rehabilitation in the prevention and management of non-communicable disease (NCD) in high-resource settings, it is not evident that these programmes can be effectively implemented in a low-resource setting (LRS). Correspondingly, it is unclear if similar benefits can be obtained. The objective of this scoping review was to summarise existing studies evaluating exercise-based rehabilitation, rehabilitation intervention characteristics and outcomes conducted in an LRS for patients with one (or more) of the major NCDs.

METHODS

The following databases were searched from inception until October 2018: PubMed/Medline, Embase, CINAHL, Cochrane Library, PsycINFO and trial registries. Studies on exercise-based rehabilitation for patients with cardiovascular disease, diabetes, cancer or chronic respiratory disease conducted in an LRS were included. Data were extracted with respect to study design (eg, type, patient sample, context), rehabilitation characteristics (eg, delivery model, programme adaptations) and included outcome measures.

RESULTS

The search yielded 5930 unique citations of which 60 unique studies were included. Study populations included patients with cardiovascular disease (48.3%), diabetes (28.3%), respiratory disease (21.7%) and cancer (1.7%). Adaptations included transition to predominant patient-driven home-based rehabilitation, training of non-conventional health workers, integration of rehabilitation in community health centres, or triage based on contextual or patient factors. Uptake of adapted rehabilitation models was 54%, retention 78% and adherence 89%. The majority of the outcome measures included were related to body function (65.7%).

CONCLUSIONS

The scope of evidence suggests that adapted exercise-based rehabilitation programmes can be implemented in LRS. However, this scope of evidence originated largely from lower middle-income, urban settings and has mostly been conducted in an academic context which may hamper extrapolation of evidence to other LRS. Cost-benefits, impact on activity limitations and participation restrictions, and subsequent mortality and morbidity are grossly understudied.

Task sharing with non-physician health-care workers for management of blood pressure in low-income and middle-income countries: a systematic review and meta-analysis

BACKGROUND

Task sharing for the management of hypertension could be useful for understaffed and resource-poor health systems. We assessed the effectiveness of task-sharing interventions in improving blood pressure control among adults in low-income and middle-income countries.

METHODS

We searched the Cochrane Library, PubMed, Embase, and CINAHL for studies published up to December 2018. We included intervention studies involving a task-sharing strategy for management of blood pressure and other cardiovascular risk factors. We extracted data on population, interventions, blood pressure, and task sharing groups. We did a meta-analysis of randomised controlled trials.

FINDINGS

We found 3012 references, of which 54 met the inclusion criteria initially. Another nine studies were included following an updated search. There were 43 trials and 20 before-and-after studies. We included 31 studies in our meta-analysis. Systolic blood pressure was decreased through task sharing in different groups of health-care workers: the mean difference was -5·34 mm Hg (95% CI -9·00 to -1·67, I2=84%) for task sharing with nurses, -8·12 mm Hg (-10·23 to -6·01, I2=57%) for pharmacists, -4·67 mm Hg (-7·09 to -2·24, I2=0%) for dietitians, -3·67 mm Hg (-4·58 to -2·77, I2=24%) for community health workers, and -4·85 mm Hg (-6·12 to -3·57, I2=76%) overall. We found a similar reduction in diastolic blood pressure (overall mean difference -2·92 mm Hg, -3·75 to -2·09, I2=80%). The overall quality of evidence based on GRADE criteria was moderate for systolic blood pressure, but low for diastolic blood pressure.

INTERPRETATION

Task-sharing interventions are effective in reducing blood pressure. Long-term studies are needed to understand their potential impact on cardiovascular outcomes and mortality.

Diabetes Self-Management Education (DSME) - Effect on Knowledge, Self-Care Behavior, and Self-Efficacy Among Type 2 Diabetes Patients in Ethiopia: A Controlled Clinical Trial

PURPOSE

Diabetes patients must be equipped with the necessary knowledge to confidently undertake appropriate self-care activities. We prepared a diabetes self-management education (DSME) intervention and assessed how it affected patients' self-reported levels of diabetes knowledge, self-care behaviors, and self-efficacy.

PATIENTS AND METHODS

A before-and-after, two-group intervention study was conducted at Jimma University Medical Centre among adult patients with type 2 diabetes. At baseline, we randomly assigned 116 participants to the DSME intervention and 104 to a comparison group. Six interactive DSME sessions supported by an illustrative handbook and fliers, experience-sharing, and take-home activities were administered to the intervention group by two nurses during a six-month period. Diabetes knowledge, self-care behaviors, and self-efficacy were measured at baseline and at nine months following the commencement of DSME intervention (endpoint) in both groups.

RESULTS

At the endpoint, data from 78 intervention group participants and 64 comparison group participants were included in final analysis. The difference in the mean Diabetes Knowledge Scale scores before and after the DSME intervention was significantly greater in the intervention group (p = 0.044). The measured self-care behaviors included diet, exercise, glucose self-monitoring, footcare, smoking, alcohol consumption, and khat chewing. The mean number of days per week on which the intervention group participants followed general dietary recommendations increased significantly at the endpoint (p = 0.027). The intervention group followed specific dietary recommendations (p = 0.019) and performed footcare (p = 0.009) for a significantly greater number of days. There were no significant differences within or between the groups in other self-reported diabetes self-care behavior regimens or in diabetes self-efficacy.

CONCLUSION

Our study found significant improvements in the intervention participants' diabetes knowledge scores and in their adherence to dietary and footcare recommendations. This demonstrates that our DSME intervention may be of clinical importance in developing countries such as Ethiopia.

Effect of nurse-led randomised control trials on cardiovascular risk factors and HbA1c in diabetes patients: A meta-analysis

A systematic review and meta-analysis identified 42 randomised control trials comparing a nurse-led intervention with 'usual care' to quantify their effect on glycated haemoglobin (HbA1c) and major cardiovascular risk factors in diabetes patients. All relevant databases were systematically searched for publications to February 2016: MEDLINE, Cochrane Central Register of Controlled Trials, EMBASE and Cumulative Index to Nursing & Allied Health Literature (CINAHL). The 42 trials recruited 9955 diabetes patients (5022 randomised to intervention and 4933 to 'usual care'). For patients receiving the nurse-led intervention, compared with 'usual care', there were small but significant mean reductions for HbA1c [-0.28%; 95% CI -0.38%, -0.18%; p-value<0.0001, n=6920] and serum triglyceride levels [-0.27mmol/L; 95% CI -0.49, -0.06; p=0.01, n=1169], and a greater proportion of patients stopped smoking [risk ratio=2.70; 95% CI 1.35, 5.43; p=0.005, n=1890 patients]. Mean reductions for systolic [-1.84mmHg; 95% CI -3.97, -0.10; p=0.06, 4241 patients] and diastolic [-0.95mmHg; 95% CI -2.15, -0.25; p=0.12, 3811 patients] blood pressures trended towards significance. There were no significant mean reductions for body mass index or serum cholesterol. Nurse-led interventions produced greater improvements than 'usual care' for HbA1c, serum triglyceride and smoking cessation and support an increased independent role for nurses in diabetes management.

Effectiveness of a community-based diabetes self-management education (DSME) program in a rural agricultural setting

Introduction The purpose of this study is to assess the effectiveness of diabetes self-management education (DSME) in a rural agricultural town.

METHODS

In this prospective, education-intervention trial, 85 adults with type 2 diabetes mellitus from villages randomly assigned to DSME and 70 from villages assigned to standard care participated. The DSME group underwent a curriculum delivered by peer educators; those in the standard group received usual advice.
