Diabetes education for Chinese adults with type 2 diabetes: A systematic review and meta-analysis of the effect on glycemic control

Diabetes knowledge predicts HbA1c levels of people with type 2 diabetes mellitus in rural China: a ten-month follow-up study

Improving diabetes self-management (DSM) is facing real-world challenges among people with type 2 diabetes mellitus (T2DM) who have a low education level in resource-limited areas. This study aimed to investigate whether diabetes knowledge could predict glycemic levels in people with T2DM in rural China. This analytical cross-sectional study recruited 321 people with T2DM from eight villages by purposive sampling at baseline. After 10 months, 206 patients completed the follow-up survey and HbA1c tests, with a response rate of 64.17% (206/321). Multiple regression analysis was employed to explore the correlation between diabetes knowledge and HbA1c levels. The patient's diabetes knowledge was significantly negatively correlated with HbA1c levels before and after controlling for covariates in both hierarchical multiple regression and multiple logistic regression (p < 0.01). In addition, other influencing factors, including sex, age, marital status, employment status, income, and HbA1c levels at baseline, were also identified. Diabetes knowledge could predict HbA1c levels significantly among patients with low education levels in rural China. Therefore, interventions on improving diabetes knowledge need to be strengthened for patients in rural China so that they can improve their health outcomes and reduce the disease burden.

Applying the theory of planned behavior to investigate type 2 diabetes patients' intention to receive injection therapy

Objectives

This study applied the theory of planned behavior (TPB) in shared decision making (SDM) to understand behavioral intention in patients with type 2 diabetes with regard to injection therapy for blood sugar control.

Methods

A cross sectional study was conducted. Two hundred and fifty-four patients with type 2 diabetes participated this study and were interviewed by pharmacists in different clinics. A patient decision aid (PDA) entitled "Should I receive injection therapy regarding my type 2 diabetes condition?" was developed for this study and served as interview agenda which comprised 18 items to inquire their willingness to use injection therapy and related considerations during the SDM process.

Results

The questionnaires were revised using item analysis, exploratory factor analysis, and a criteria of Cronbach's α > 0.7. This resulted in three constructs for all questionnaires that fit the TPB model. Attitude (β = 0.432; P < 0.001) and PBC (β = 0.258; P < 0.001) were directly correlated with intention. TPB explained 35.2% of the variance in intention toward the use of injection therapy.

Conclusions

Attitude and PBC toward injection therapy positively and significantly influence the patients' intention to use injection therapy.

Practical implications

These findings identify a key association for understanding behavioral intention in patients with type 2 diabetes with regard to blood sugar control during SDM.

Nursing Interns' Attitudes Toward, Preferences for, and Use of Diabetes Virtual Simulation Teaching Applications in China: National Web-Based Survey

BACKGROUND

Diabetes has placed heavy social and economic burdens on society and families worldwide. Insufficient knowledge and training of frontline medical staff, such as nurses, interns, and residents, may lead to an increase in acute and chronic complications among patients with diabetes. However, interns have insufficient knowledge about diabetes management. The factors that affect interns' current level of diabetes-related knowledge are still unclear. Therefore, understanding the behavioral intentions of interns is essential to supporting the development and promotion of the use of virtual simulation teaching applications.

OBJECTIVE

This study aimed to identify the determinants of nursing interns' intentions to use simulation-based education applications.

METHODS

From December 1, 2020, to February 28, 2021, the web-based survey tool Sojump (Changsha Xingxin Information Technology Co) was used to survey nursing interns in hospitals across China. Two survey links were sent to 37 partner schools in 23 major cities in China, and they were disseminated through participants' WeChat networks. Multiple regression analysis was used to determine the association between demographic information and basic disease information and the use of the application for treating adult patients.

RESULTS

Overall, 883 nursing interns from 23 provinces in China responded to the survey. Among them, the virtual simulation utilization rate was 35.6% (314/883) and the awareness rate was 10.2% (90/883). In addition, among the interns, only 10.2% (90/883) correctly understood the concept of virtual simulation, and most of them (793/883, 89.8%) believed that scenario-simulation training or the use of models for teaching are all the same. Multiple regression analysis showed that the educational level, independent learning ability, and professional identity of the interns were related to use of the application (P<.05). Skills and knowledge that the interns most wanted to acquire included the treatment of hypoglycemia (626/883, 70.9%), functional test simulation (610/883, 69.1%), and blood glucose monitoring technology (485/883, 54.9%). A total of 60.5% (534/883) of the interns wanted to acquire clinical thinking skills, while 16.0% (141/883) wanted to acquire operational skills. Nursing trainees believed that the greatest obstacles to virtual simulation included limited time (280/883, 31.7%), the degree of simulation (129/883, 14.6%), the demand for satisfaction (108/883, 12.2%), and test scores (66/883, 7.5%).

CONCLUSIONS

The understanding and usage rate of diabetes virtual simulation teaching applications by Chinese nursing interns is very low. However, they have high requirements regarding this teaching method. Conducting high-quality randomized controlled trials and designing applications that are suitable for the needs of different nurse trainees will increase students' interest in learning and help improve diabetes knowledge among nursing interns.

Effectiveness of the Family Portal Function on the Lilly Connected Care Program (LCCP) for Patients With Type 2 Diabetes: Retrospective Cohort Study With Propensity Score Matching

Background

Diabetes is a major health concern worldwide. Family member engagement in diabetes self-management education programs can improve patients’ diabetes management. However, there is limited evidence that the family portal on diabetes management apps is effective in the glycemic control of patients with diabetes.

Objective

We aimed to evaluate the effectiveness of family support through the family portal function on Lilly Connected Care Program (LCCP) platform.

Methods

This retrospective cohort study included patients with type 2 diabetes recruited to the LCCP platform from September 1, 2018, to August 31, 2019. Propensity score matching was used to match family (group A) and non–family (group B) portal use groups with similar baseline characteristics. The patients were followed up with for 12 weeks. The main objectives were differences in mean fasting blood glucose, proportion of patients achieving fasting blood glucose target <7mmol/L, mean postprandial blood glucose, proportion of patients achieving postprandial blood glucose target <10mmol/L, proportion of patients achieving both fasting blood glucose <7mmol/L and postprandial blood glucose <10mmol/L, self-monitoring of blood glucose frequency at week 12 and the number of diabetes education courses patients completed during the 12 weeks. Moreover, logistic regression analysis was used to explore the baseline factors which may be associated with the use of family portal, and odds ratios with 95% confidence intervals were calculated.

Results

A total of 6582 adult patients (aged ≥18 years) with type 2 diabetes who were receiving insulin therapy were enrolled in the study. Overall, 6.1% (402/6582) of the patients chose to engage their family members to use the family portal. Two groups of 394 patients were well-matched regarding baseline characteristics. After matching, mean fasting blood glucose and postprandial blood glucose at week 12 were significantly lower in group A than in group B (fasting blood glucose: 7.12 mmol/L, SD 1.70 vs 7.42 mmol/L, SD 1.88, respectively, P=.02; postprandial blood glucose: 8.56 mmol/L, SD 2.51 vs 9.10 mmol/L, SD 2.69, respectively, P=.002). When comparing group A to group B, the proportion of patients achieving both fasting blood glucose <7mmol and postprandial blood glucose <10mmol/L at week 12 (46.8% vs 39.4%, respectively, P=.04), self-monitoring of blood glucose frequency at week 12 (8.92 times per week, SD 6.77 vs 8.02 times per week, SD 5.97, respectively, P=.05) and number of diabetes education courses completed in 12 weeks (23.00, IQR9.00-38.00 vs 15.00, IQR 4.00-36.00, respectively, P<.001) was higher. Additionally, multivariate logistic regression analysis showed that higher age (OR=0.987, 95% CI 0.978-0.996, P=.006) and higher baseline fasting blood glucose (OR=0.914, 95% CI 0.859-0.972, P=.004) were correlated with less use of the family portal function, while increased baseline self-monitoring of blood glucose frequency (OR=1.022, 95% CI 1.012-1.032], P<.001) as well as increased education courses (OR=1.026, 95% CI 1.015-1.036, P<.001) were associated with more use of the family portal function.

Conclusions

Family support through the LCCP family portal is effective for glycemic control and self-management behavior improvement in type 2 diabetes patients.

Not Scared of Sugar™: Outcomes of a structured type 2 diabetes group education program for Chinese Australians

Type 2 diabetes disproportionately affects the Chinese population yet there are no structured diabetes education programs specifically designed for this community in Australia. This project aimed to develop and evaluate a pilot type 2 diabetes group education program designed specifically for Chinese migrants living in Australia. A non-randomised pre- versus post-intervention trial was conducted between March 2017 and November 2018. A culturally tailored group education program (Not Scared of Sugar™) was developed and piloted with Melbourne-based Cantonese-speaking people with type 2 diabetes. Program teaching styles were aligned with the Confucian cultural process of learning and incorporated culturally specific strategies to promote healthy behaviour change. Thirty-four individuals (35% male) attended five education sessions over ten weeks, delivered by a Cantonese-speaking facilitator and multidisciplinary clinicians. Data were collected from participants at baseline, on program completion and at 6 months follow-up. Mean (SD) participant age was 69 (9) years, with a mean time of 25.7 (10.8) years in Australia and a median duration of diabetes of 10 (IQR = 2.8-20.5) years. At program completion, mean participant waist circumference (90.5 versus 89.2 cm, p < .001) and waist-to-height ratio (0.574 vs. 0.566, p < .001) was significantly reduced and both were further reduced at 6-month follow-up (p < .05). There was a significant increase in the median frequency of diabetes self-care behaviours undertaken, with American Association of Diabetes Educators Questionnaire Score: 30 (22-32.3) versus 33 (29.8-35.0), p < .001 at 6-month follow-up. Diabetes-related distress assessed by PAID-C was also significantly reduced at 6-month follow-up (p < .05). Mean HbA1c was unchanged after 6 months; 51 (7.9) versus 50 (7.8) mmol/mol, p = .316. Program attrition was 6%. Not Scared of Sugar™ successfully reduced waist circumference, increased diabetes self-management behaviours and reduced diabetes distress in Cantonese-speaking Australians, which may positively impact long-term risk of vascular complications.

Psychometric Testing of an Indonesian-Version Diabetes Self-Management Instrument

Background

Self-management is one of the vital elements in diabetes management for adults with Type 2 diabetes mellitus (T2DM). Although the number of people with T2DM in Indonesia has risen, clinical understanding of the problems related to practicing diabetes self-management (DSM) is limited because of the lack of a valid measurement instrument. The 35-item Diabetes Self-Management Instrument (DSMI-35) is one instrument widely used in research to assess DSM-related behavior among patients with diabetes.

Purpose

This study was designed to translate the psychometric properties of the Indonesian version of the DSMI-35 and evaluate the efficacy of this instrument in a sample of Indonesian adults with T2DM.

Methods

Forward and backward translation processes were used to translate the DSMI-35 into Indonesian (IDN-DSMI). Then, the translation equivalence, content validity, face validity, construct validity, and internal consistency were assessed using a sample of 222 Indonesian adults with T2DM from eight public health centers. Confirmatory factor analysis was used to test the data.

Results

The confirmatory factor analysis confirmed that the 35 items all had acceptable goodness of fit. Although the analysis supported removing several of the items, removal of these items was not theoretically justified. The average variance extracted was acceptable, and composite reliability was satisfied. The Cronbach's alpha was .96 for the IDN-DSMI and .84–.93 for the subscales. The significant interitem correlations between some items were consistent with the findings of other previous studies.

Conclusions/Implications for Practice

The IDN-DSMI is a valid and reliable instrument that may be used to measure DSM behavior in Indonesian patients with T2DM in primary healthcare settings.

Study protocol for the road to hierarchical diabetes management at primary care (ROADMAP) study in China: a cluster randomised controlled trial

INTRODUCTION

Diabetes management in primary care remains suboptimal in China, despite its inclusion in the essential public health service (EPHS). We aimed to evaluate the effectiveness of a mobile health (mHealth) based and three-tiered diabetes management system in diverse Chinese contexts.

METHODS AND ANALYSIS

This is a cluster randomised controlled trial, named road to hierarchical diabetes management at primary care (ROADMAP). 19 008 patients with type 2 diabetes (T2D) were recruited from primary care clinics in 864 communities across 144 counties/districts of 24 provinces. Eligible participants were adult patients diagnosed with T2D and registered for diabetes management in communities. Patients within the same communities (clusters) were randomly allocated into the intervention or control arm for 1 year in a 2:1 ratio. The control arm patients received usual care as EPHS packaged: at least four blood glucose (BG) and blood pressure (BP) tests, and lifestyle and medication instruction, yearly, from primary care providers. The intervention arm patients received at least two BG and one BP tests, monthly, and lifestyle and treatment instruction from a three-tiered contracted team. A mHealth platform, Graded ROADMAP, enabled test results uploading and sharing, and patient referral within the team. The intervention participants will be further divided into basic or intensive intervention group according to whether they were actively using the Your Doctor App. The primary outcome is the BG control rate with glycated haemoglobin (HbA1c)<7.0%. Secondary outcomes include control rates and changes of ABC (HbA1c, BP and low-density lipoprotein cholesterol) and fasting BG, hypoglycaemia episodes and health-related quality of life (EuroQol (EQ-5D)).

ETHICS AND DISSEMINATION

The trial has been approved by the Institutional Review Board at Shanghai Sixth People's Hospital. Findings on the intervention effectiveness will be disseminated through peer-reviewed journals, conference presentations and other relevant mechanisms.

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.

An Autoethnographic Account of a Bicultural Clinician-Researcher Applying New Evidence of Chinese Diabetes Education Into Practice

Introduction: A clinician-researcher in translational research fulfils obligations in care provision and knowledge generation. Similarly, a bicultural clinician could struggle to switch between cultural paradigms. The purpose of this study was to explore the in-depth experience of multiple roles as a bicultural clinician-researcher in a translational research study. Methods: This study employed an autoethnographical method, where the first author, an Australian-trained Chinese researcher, was the research instrument who critically sought understanding of her experience in relation to culture in the context of translating an evidence-based culturally tailored Chinese diabetes education program into practice. Data were thematically analyzed and triangulated. Results: Specific research-to-practice dilemmas and personal and professional growth experiences were encountered. Learning to be flexible in addressing patients' needs while concurrently collecting program evaluation data was complicated by self-doubt and inflexible colleagues. Implication: Despite challenges, conducting translational research with clinician-researcher can enhance understanding of the different stakeholder cultures, promoting rapid practice change.

The combined diabetes and renal control trial (C-DIRECT) - a feasibility randomised controlled trial to evaluate outcomes in multi-morbid patients with diabetes and on dialysis using a mixed methods approach

BACKGROUND

This cluster randomised controlled trial set out to investigate the feasibility and acceptability of the "Combined Diabetes and Renal Control Trial" (C-DIRECT) intervention, a nurse-led intervention based on motivational interviewing and self-management in patients with coexisting end stage renal diseases and diabetes mellitus (DM ESRD). Its efficacy to improve glycaemic control, as well as psychosocial and self-care outcomes were also evaluated as secondary outcomes.

METHODS

An assessor-blinded, clustered randomised-controlled trial was conducted with 44 haemodialysis patients with DM ESRD and ≥ 8% glycated haemoglobin (HbA1c), in dialysis centres across Singapore. Patients were randomised according to dialysis shifts. 20 patients were assigned to intervention and 24 were in usual care. The C-DIRECT intervention consisted of three weekly chair-side sessions delivered by diabetes specialist nurses. Data on recruitment, randomisation, and retention, and secondary outcomes such as clinical endpoints, emotional distress, adherence, and self-management skills measures were obtained at baseline and at 12 weeks follow-up. A qualitative evaluation using interviews was conducted at the end of the trial.

RESULTS

Of the 44 recruited at baseline, 42 patients were evaluated at follow-up. One patient died, and one discontinued the study due to deteriorating health. Recruitment, retention, and acceptability rates of C-DIRECT were generally satisfactory HbA1c levels decreased in both groups, but C-DIRECT had more participants with HbA1c < 8% at follow up compared to usual care. Significant improvements in role limitations due to physical health were noted for C-DIRECT whereas levels remained stable in usual care. No statistically significant differences between groups were observed for other clinical markers and other patient-reported outcomes. There were no adverse effects.

CONCLUSIONS

The trial demonstrated satisfactory feasibility. A brief intervention delivered on bedside as part of routine dialysis care showed some benefits in glycaemic control and on QOL domain compared with usual care, although no effect was observed in other secondary outcomes. Further research is needed to design and assess interventions to promote diabetes self-management in socially vulnerable patients.

TRIAL REGISTRATION NUMBER

Trial registered with the International Standard Randomised Controlled Trial (ISRCTN10546597). Registered 12 September 2016 (Retrospectively registered).

Supported self-management for people with type 2 diabetes: a meta-review of quantitative systematic reviews

OBJECTIVES

Self-management support aims to give people with chronic disease confidence to actively manage their disease, in partnership with their healthcare provider. A meta-review can inform policy-makers and healthcare managers about the effectiveness of self-management support strategies for people with type 2 diabetes, and which interventions work best and for whom.

DESIGN

A meta-review of systematic reviews of randomised controlled trials (RCTs) was performed adapting Cochrane methodology.

SETTING AND PARTICIPANTS

Eight databases were searched for systematic reviews of RCTs from January 1993 to October 2016, with a pre-publication update in April 2017. Forward citation was performed on included reviews in Institute for Scientific Information (ISI) Proceedings. We extracted data and assessed quality with the Revised-Assessment of Multiple Systematic Reviews (R-AMSTAR).

PRIMARY AND SECONDARY OUTCOME MEASURES

Glycaemic control as measured by glycated haemoglobin (HbA1c) was the primary outcome. Body mass Index, lipid profiles, blood pressure and quality of life scoring were secondary outcomes. Meta-analyses reporting HbA1c were summarised in meta-forest plots; other outcomes were synthesised narratively.

RESULTS

41 systematic reviews incorporating data from 459 unique RCTs in diverse socio-economic and ethnic communities across 33 countries were included. R-AMSTAR quality score ranged from 20 to 42 (maximum 44). Apart from one outlier, the majority of reviews found an HbA1c improvement between 0.2% and 0.6% (2.2-6.5 mmol/mol) at 6 months post-intervention, but attenuated at 12 and 24 months. Impact on secondary outcomes was inconsistent and generally non-significant. Diverse self-management support strategies were employed; no single approach appeared optimally effective (or ineffective). Effective programmes tended to be multi-component and provide adequate contact time (>10 hours). Technology-facilitated self-management support showed a similar impact as traditional approaches (HbA1c MD -0.21% to -0.6%).

CONCLUSIONS

Self-management interventions using a range of approaches improve short-term glycaemic control in people with type 2 diabetes including culturally diverse populations. These findings can inform researchers, policy-makers and healthcare professionals re-evaluating the provision of self-management support in routine care. Further research should consider implementation and sustainability.

Correlation between glycemic control and knowledge in patients with type 2 diabetes mellitus treated at the Family Health Center of the Araucanía region, Chile

Introduction: Diabetes mellitus type 2 (DM2) is a public health problem considering its magnitude and repercussions.Objective: To determine the correlation between glycemic control and the level of knowledge about their disease in patients with DM2.Materials and methods: The sample consisted of 65 adults with DM2, aged between 55 and 74 years. The Michigan Diabetes Research and Training Center’s Revised Diabetes Knowledge Test was applied to measure the level of knowledge about DM2. Glycemic control was determined based on the last glycosylated hemoglobin value. Information on educational attainment, years of diagnosis of the disease and use of insulin therapy was obtained from clinical records.Results: Patients with a sufficient level of knowledge of their disease had better glycemic control than those whose knowledge was insufficient (p<0.001). There were no differences when comparing educational attainment (p=0.201), years of diagnosis of the disease (p=0.126) and insulin use (p=0.108) with glycemic control.Conclusion: Glycemic control in DM2 patients can be improved by delivering tools that allow them to be empowered with knowledge about their disease, regardless of their educational attainment, the duration of the disease course or the type of treatment.

The impact of inpatient education on self-management for patients with acute coronary syndrome and type 2 diabetes mellitus: a cross-sectional study in China

This study examined the impact of inpatient education on diabetes knowledge, acute coronary syndrome (ACS) symptom management and diabetes self-management on discharge for patients with ACS and type 2 diabetes mellitus (T2DM). A cross-sectional survey and patient health record review of 160 patients was conducted in a major hospital in Shanghai. Patient education received was measured using a visual analogue scale. The survey included valid and reliable measures of diabetes knowledge, self-efficacy, attitudes to ACS and clinical outcomes. Inpatient education contributed to improvements in fasting blood glucose on discharge (P < 0.05). ACS symptom management [Chinese language version of the ACS response index (C-ACSRI) scores] and self-management of T2DM [Chinese version of diabetes management self-efficacy scale (C-DMSES) scores] on discharge differed for the limited education group and sufficient education group (P < 0.001). Based on the multiple regression analyses, increasing scores for the C-ASCRI and C-DMSES could be explained by higher scores for perceived health education. Education relating to ACS and T2DM delivered during an acute admission was associated with improved scores in ACS symptom management and T2DM self-management, preparing some patients to manage both conditions on discharge.

Interventions designed to reduce excessive gestational weight gain can reduce the incidence of gestational diabetes mellitus: A systematic review and meta-analysis of randomised controlled trials

AIMS

To (i) evaluate the global impact of interventions designed to prevent excessive gestational weight gain (eGWG) on the incidence of gestational diabetes (GDM), and (ii) examine whether the effects differ by pre-conception body mass index (BMI) or ethnicity.

METHODS

A systematic search of randomised controlled trials (RCTs) with a primary or secondary aim to reduce eGWG was conducted in seven international and three Chinese databases without date limits. Meta-analysis data are reported as relative risk (RR) for GDM incidence for interventions including: diet, physical activity (PA), and lifestyle (diet and PA).

RESULTS

Forty-five studies were included, 37 in the meta-analyses. Diet and PA interventions reduced GDM risk by 44% (RR: 0.56, 95% CI: 0.36-0.87) and 38% (RR: 0.62, 95% CI: 0.50-0.78), respectively. Lifestyle interventions and BMI didn't significantly alter GDM risk. PA interventions from Southern-Europe reduced GDM risk by 37% (RR: 0.63, 95% CI: 0.50-0.80). Whereas, diet and lifestyle interventions conducted in Asia reduced GDM risk by 62% (RR: 0.38, 95% CI: 0.24-0.59) and 32% (RR: 0.68, 95% CI: 0.54-0.86), respectively.

CONCLUSION

Diet and PA interventions designed to reduce GWG are more effective than standard care in reducing the incidence of GDM, although the effect varies by region and BMI. The 'one size fits all' approach is not supported.

The effectiveness of theory- and model-based lifestyle interventions on HbA1c among patients with type 2 diabetes: a systematic review and meta-analysis

OBJECTIVES

The prevalence of type 2 diabetes is rising rapidly around the world. A number of systematic reviews have provided evidence for the effectiveness of lifestyle interventions on diabetic patients. The effectiveness of theory- and model-based education-lifestyle interventions for diabetic patients are unclear. The systematic review and meta-analysis aimed to evaluate and quantify the impact of theory-based lifestyle interventions on type 2 diabetes.

STUDY DESIGN

A literature search of authentic electronic resources including PubMed, Scopus, and Cochrane collaboration was performed to identify published papers between January 2002 and July 2016.

METHODS

The PICOs (participants, intervention, comparison, and outcomes) elements were used for the selection of studies to meet the inclusion and exclusion criteria. Mean differences and standard deviations of hemoglobin A1c (HbA1c [mmol/mol]) level in baseline and follow-up measures of studies in intervention and control groups were considered for data synthesis. A random-effects model was used for estimating pooled effect sizes. To investigate the source of heterogeneity, predefined subgroup analyses were performed using trial duration, baseline HbA1c (mmol/mol) level, and the age of participants. Meta-regression was performed to examine the contribution of trial duration, baseline HbA1c (mmol/mol) level, the age of participants, and mean differences of HbA1c (mmol/mol) level. The significant level was considered P < 0.05.

RESULTS

Eighteen studies with 2384 participants met the inclusion criteria. The pooled main outcomes by random-effects model showed significant improvements in HbA1c (mmol/mol) -5.35% (95% confidence interval = -6.3, -4.40; P < 0.001) with the evidence of heterogeneity across studies.

CONCLUSION

The findings of this meta-analysis suggest that theory- and model-based lifestyle interventions have positive effects on HbA1c (mmol/mol) indices in patients with type 2 diabetes. Health education theories have been applied as a useful tool for lifestyle change among people with type 2 diabetes.

Diabetes management in a foreign land: A case study on Chinese Australians

The aim of this study was to understand the experience of Chinese migrants living with type 2 diabetes in Australia and explore their culturally specific diabetes management needs, habits and expectations in the Australian context to help shape an Australian Chinese diabetes service. A case study approach was employed across two Australian cities (Melbourne and Sydney), using participant-observations and qualitative interviews. Purposive sampling was used to find diabetes education sessions for observation and facilitators for interviews before snowball technique was used to identify relevant clinicians. Thematic analysis with pattern matching was used for data analysis. A total of 18 participant-observations and 12 interviews were conducted. Chinese migrants appeared to experience multiple barriers in accessing the Australian diabetes care service further complicated by the mismatch between the expectations of Chinese patients and the services available. Chinese patients were observed to be collectivistic-orientated relying on friends for diabetes management. While health professionals appeared to be perceived as a source of reputable health information, they often did not provide ongoing support. When professional support was limited, Chinese patients adopted alternative strategies to address their diabetes, which often involved seeking help and information from peers. Some of this information was non-reputable, potentially resulting in detrimental health outcomes. In conclusion, redesigning diabetes care services in line with the principles of collectivism may more appropriately match the Chinese migrants' expectations and needs, and better support them in their diabetes journey.

Health education for patients with acute coronary syndrome and type 2 diabetes mellitus: an umbrella review of systematic reviews and meta-analyses

OBJECTIVES

This umbrella review aimed to identify the current evidence on health education-related interventions for patients with acute coronary syndrome (ACS) or type two diabetes mellitus (T2DM); identify the educational content, delivery methods, intensity, duration and setting required. The purpose was to provide recommendations for educational interventions for high-risk patients with both ACS and T2DM.

DESIGN

Umbrella review of systematic reviews and meta-analyses.

SETTING

Inpatient and postdischarge settings.

PARTICIPANTS

Patients with ACS and T2DM.

DATA SOURCES

CINAHL, Cochrane Library, Joanna Briggs Institute, Journals@Ovid, EMBase, Medline, PubMed and Web of Science databases from January 2000 through May 2016.

OUTCOMES MEASURES

Clinical outcomes (such as glycated haemoglobin), behavioural outcomes (such as smoking), psychosocial outcomes (such as anxiety) and medical service use.

RESULTS

Fifty-one eligible reviews (15 for ACS and 36 for T2DM) consisting of 1324 relevant studies involving 2 88 057 patients (15 papers did not provide the total sample); 30 (58.8%) reviews were rated as high quality. Nurses only and multidisciplinary teams were the most frequent professionals to provide education, and most educational interventions were delivered postdischarge. Face-to-face sessions were the most common delivery formats, and many education sessions were also delivered by telephone or via web contact. The frequency of educational sessions was weekly or monthly, and an average of 3.7 topics was covered per education session. Psychoeducational interventions were generally effective at reducing smoking and admissions for patients with ACS. Culturally appropriate health education, self-management educational interventions, group medical visits and psychoeducational interventions were generally effective for patients with T2DM.

CONCLUSIONS

Results indicate that there is a body of current evidence about the efficacy of health education, its content and delivery methods for patients with ACS or T2DM. These results provide recommendations about the content for, and approach to, health education intervention for these high-risk patients.
