Testing a peer support intervention for people with type 2 diabetes: a pilot for a randomised controlled trial

“I Could Have Stood a Little More Education Rather than Just: ‘Hey, you’re Diabetic Man, Make the Best out of It’”: Revisioning Diabetes Self-Management Education for Older Adults

Objectives: Providing diabetes self-management education (DSME) in an evidence-based format that is accessible and tailored to the population needs is crucial for individuals living with diabetes mellitus. Our qualitative study explores the experiences of older adults living with diabetes while residing in a rural setting. Methods: Adults aged 65 or older and residing in a rural area of Ontario completed a photovoice activity and semi-structured interviews to illustrate their experience of living with diabetes and accessing DSME. Results: Fourteen participants (11 males; mean age = 74 years) completed the photovoice activity and interview. Four main themes were identified pertaining to learning about diabetes education, the depth and breadth of learning, applying knowledge to daily life, and engaging older adults in DSME. Discussion: Diabetes self-management education should account for older adults’ preferences in learning about diabetes and self-management to promote access to evidence-based information, bolster knowledge and self-management efficacy, and improve disease control.

Predictors and Effects of Participation in Peer Support: A Prospective Structural Equation Modeling Analysis

BACKGROUND

Peer support provides varied health benefits, but how it achieves these benefits is not well understood.

PURPOSE

Examine a) predictors of participation in peer support interventions for diabetes management, and b) relationship between participation and glycemic control.

METHODS

Seven peer support interventions funded through Peers for Progress provided pre/post data on 1,746 participants' glycemic control (hemoglobin A1c), contacts with peer supporters as an indicator of participation, health literacy, availability/satisfaction with support for diabetes management from family and clinical team, quality of life (EQ-Index), diabetes distress, depression (PHQ-8), BMI, gender, age, education, and years with diabetes.

RESULTS

Structural equation modeling indicated a) lower levels of available support for diabetes management, higher depression scores, and older age predicted more contacts with peer supporters, and b) more contacts predicted lower levels of final HbA1c as did lower baseline levels of BMI and diabetes distress and fewer years living with diabetes. Parallel effects of contacts on HbA1c, although not statistically significant, were observed among those with baseline HbA1c values > 7.5% or > 9%. Additionally, no, low, moderate, and high contacts showed a significant linear, dose-response relationship with final HbA1c. Baseline and covariate-adjusted, final HbA1c was 8.18% versus 7.86% for those with no versus high contacts.

CONCLUSIONS

Peer support reached/benefitted those at greater disadvantage. Less social support for dealing with diabetes and higher PHQ-8 scores predicted greater participation in peer support. Participation in turn predicted lower HbA1c across levels of baseline HbA1c, and in a dose-response relationship across levels of participation.

The Effect of Using Peer on Self-Care, Quality of Life, and Adherence in Elderly People with Coronary Artery Disease

Introduction

Coronary artery disease is one of the most common diseases and the cause of death among elderly people. Due to the chronic nature of this disease, regular follow-up, lifestyle changes, and adherence to recommendations can reduce the complications and improve the quality of life among elderly individuals. Given the importance of using educational methods that are based on the patient's age and disease stage, the present study aimed to investigate the effect of using a peer group on self-care, adherence, and quality of life in elderly people.

Method

This single-blind clinical trial was conducted on 30 old patients with coronary artery disease aged 60 years in Shiraz from March to June 2021. The patients were selected using simple random sampling and were then randomly assigned to the peer education and control groups (15 participants in each group) via permuted block randomization. The patients in the peer education group received the necessary education about medications, lifestyle, daily activities, self-care, and adherence through three educational clips by educated peer. The patients in the control group received routine education using two clips by the ward nurses. The levels of self-care, adherence, and quality of life were assessed in the intervention and control groups before and one month after the intervention. Data analysis was performed by SPSS 20 software using an independent t-test, paired sample t-test, and chi-square test. P < 0.05 was considered statistically significant. Findings. The results showed no statistically significant difference between the two groups with respect to the mean scores of self-care and quality of life before the intervention (P > 0.05). Following the educational intervention, however, a statistically significant difference was found between the two groups concerning the mean scores of self-care and adherence (P < 0.05). Moreover, the mean differences between the two groups regarding the three variables were statistically significant before and after the intervention (P < 0.05).

Conclusion

Education based on multimedia clips by peer was effective in increasing the mean scores of self-care, adherence, and quality of life among the elderly people with coronary artery disease. Given the low cost, high effectiveness, and decrease in the nurses' workload, this method is recommended to be used alongside other methods in order to educate elderly individuals suffering from coronary artery disease.

Exploring the feasibility, acceptability and value of volunteer peer mentors in supporting self-management of osteoarthritis: a qualitative evaluation

BACKGROUND

Hip and knee osteoarthritis (OA) affect a large and growing proportion of the population. Treatment options are typically conservative making self-management a priority. Using trained peers to support individuals with OA has potential to improve self-management.

PURPOSE

To explore the process of engaging and training volunteers to become peer mentors; and to qualitatively evaluate the feasibility, acceptability and value of being a peer mentor to support others' self-management of OA.

MATERIALS AND METHODS

A qualitative evaluation of a peer mentorship support intervention reporting the processes of recruitment and training; and semi-structured interviews conducted with nine active peer mentors. Transcribed interviews were coded and analysed using framework analysis.

RESULTS

It was possible to recruit, train and retain volunteers with OA to become peer mentors. The peer mentors benefitted from their training and felt equipped to deliver the intervention. They enjoyed social elements of the mentorship intervention and gained satisfaction through delivering valued support to mentees. Peer mentors perceived the mentorship intervention to have a positive impact on self-management of OA for mentees.

CONCLUSION

Training volunteers with OA to become peer mentors was feasible and acceptable. Peer mentors perceived their support benefitted others with OA. They positively rated their experience of providing mentorship support.IMPLICATIONS FOR REHABILITATIONThis study demonstrates that it is possible to recruit, train and engage older volunteers to become peer mentors for people with osteoarthritis.Training should highlight the significance of employing key self-management techniques such as goal-setting.Peer mentors acknowledged that they benefitted from training and delivering the mentorship intervention, and this impacted positively on their own osteoarthritis self-management.Careful consideration of matching mentors and mentees appears to enhance the success of mentorship support.Recognising the impact of mentorship support on mentees' self-management is central to peer mentors' sustained engagement with the intervention.

Peer Mentors for People with Advanced Cancer: Lessons Learnt from Recruiting and Training Peer Mentors for a Feasibility Randomized Controlled Trial

Peer mentors may offer distinctive forms of support to people with advanced cancer. Whilst peer mentor programmes are known, little is understood about recruiting and training peer mentors to support those with advanced cancer. The purpose of this study is to determine the feasibility of recruiting and training peer mentors for a novel peer mentor intervention to promote well-being in people with advanced cancer. Feasibility study testing proactive introduction to a trained peer mentor for 12 weeks in the context of a randomized controlled two-arm trial and nested qualitative process evaluation was used. Peer mentors have/had cancer, recruited via an open call. Two-day training included a new bespoke module on coping with cancer. Descriptive recruitment and training data were captured, supplemented by qualitative interviews, analysed thematically. Forty-eight people expressed interest, mostly female (69%), with breast cancer (32%), and recruited via social media (49%). Twelve people completed training, with attrition often due to availability or mentors' own health; many had advanced cancer themselves. They wanted to 'give something back', but also formed supportive bonds with fellow mentors. It is feasible to recruit and train people with lived experience of cancer to be peer mentors, but those with particular characteristics may predominate. Broad social media based recruitment may have merit in widening the pool of potential peer mentors.

Peer mentorship to improve self-management of hip and knee osteoarthritis: a randomised feasibility trial

OBJECTIVE

To determine the feasibility of conducting a randomised controlled trial (RCT) of a peer mentorship intervention to improve self-management of osteoarthritis (OA).

DESIGN

Six-month parallel group non-blinded randomised feasibility trial.

SETTING

One secondary care and one primary care UK National Health Service Trust.

PARTICIPANTS

Fifty adults aged ≥55 years old with hip and/or knee OA.

INTERVENTIONS

Participants were allocated 1:1 to the intervention or control group using an online randomisation service. Intervention group participants received usual care (information resources) and up to eight community-based self-management support sessions delivered by a peer mentor (trained volunteer with hip and/or knee OA). Control group participants received usual care only.

OUTCOME MEASURES

Key feasibility outcomes were participant and peer mentor recruitment and attrition, intervention completion and the sample size required for a definitive RCT. Based on these feasibility outcomes, four success criteria for proceeding to a definitive RCT were prespecified. Patient-reported outcomes were collected via questionnaires at baseline, 8 weeks and 6 months.

RESULTS

Ninety-six individuals were screened, 65 were eligible and 50 were randomised (25 per group). Of the 24 participants who commenced the intervention, 20 completed it. Four participants did not complete the 6-month questionnaire. Twenty-one individuals were eligible for the peer mentor role, 15 were trained and 5 withdrew prior to being matched with a participant. No intervention-related harms occurred. Allowing for 20% attrition, the sample size required for a definitive RCT was calculated as 170 participants. The intervention group showed improvements in self-management compared with the control group.

CONCLUSIONS

The feasibility outcomes achieved the prespecified criteria for proceeding to an RCT. The exploratory analyses suggest peer mentorship may improve OA self-management. An RCT of the OA peer mentorship intervention is therefore warranted with minor modifications to the intervention and trial procedures.

Peer-to-Peer Support and Changes in Health and Well-being in Older Adults Over Time

IMPORTANCE

Literature on peer-to-peer (P2P) programs suggests they improve health and well-being of older adults. Analysis from a previous study showed P2P to be associated with higher rates of hospitalization and no significant differences in rates of emergency department or urgent care visits; however, it is not known whether measures of health and well-being varied by group over time.

OBJECTIVE

To compare the association between receiving P2P support and secondary outcomes (ie, health status, quality of life, and depressive and anxiety symptoms) with receiving standard community services (SCS) over time.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study was conducted among a volunteer sample of older adults (≥65 years) who were new to P2P or were already receiving P2P and a corresponding control group. Participants were matched between groups on age, sex, and race/ethnicity. The study was conducted from March 2015 to December 2017 at 3 community-based organizations that delivered P2P in California, Florida, and New York. Data analysis was performed from October 2018 through May 2020.

EXPOSURES

P2P support, provided by trained older adult volunteers.

MAIN OUTCOMES AND MEASURES

Mental and physical components of the health status and quality of life measure and depressive and anxiety symptoms were collected over 12 months. The hypothesis was that older adults receiving P2P support would maintain higher health status and quality of life than the SCS group.

RESULTS

A total of 503 participants were screened, 456 participants were enrolled and had baseline data, and 8 participants only had baseline information with no follow-up data, leaving 448 participants (231 [52%] in the SCS group; 217 [48%] in the P2P group; 363 [81%] women; mean [SD] age, 80 [9] years). The P2P group had improvements in mental health (change at 12 months, 1.1 points; 95% CI, -0.8 to 3.0 points) and physical health (change at 12 months, 1.0 points; 95% CI, -0.7 to 2.8 points). However, the difference of differences between the 2 groups did not differ significantly from baseline to 12 months (mental health: 0.2 points; 95% CI -2.3 to 2.7 points; physical health: 1.7 points; 95% CI, -0.6 to 3.9 points). The P2P and SCS groups had a statistically significant difference of differences in anxiety symptoms of 0.36 points (95% CI, 0.04 to 0.61 points). There were no significant differences in depressive symptoms or mental and physical components of the health status and quality of life.

CONCLUSIONS AND RELEVANCE

These findings suggest that receiving P2P support did not slow the decline of health and well-being in older adults compared with those who received SCS. Baseline imbalance in key characteristics, even after adjusting for the imbalance using the propensity score method, may explain the results. Randomized trials are needed.

The effect of peer group on self-care behaviors and glycemic index in elders with type II diabetes

BACKGROUND

Diabetes is one of the most expensive and chronic diseases of elderly age. Knowledge and self-care behaviors play an important role in treating diabetes and preventing its side effects. This study aimed to investigate the effect of peer group on self-care behaviors and glycemic index in the elderly with type II diabetes mellitus in Fasa city, Fars province.

MATERIALS AND METHODS

This quasi-experimental study was conducted on 100 elderly patients with type II diabetes (50 patients in the intervention group and 50 in control group) referred to the diabetes center. Among the elderly, the intervention group was selected as a trainer based on the checklist of the peer group and was trained by the researcher. In addition to the usual care of the diabetes clinic, the patients in the intervention group received training from their peers for 8 weeks during 8-45 min of training sessions. Data were collected using a valid self-reported questionnaire including demographic variables, awareness, and diabetes self-care behaviors (Summary of Diabetes Self-care Activities), as well as free practice (fasting blood sugar [FBS] and hemoglobin A1c [HbA1c]), which was completed by both groups before and 2 months after the intervention. Then, the data were entered into the SPSS statistical software, version 22 and were analyzed using Chi-square test, independent t-test, and descriptive statistical methods. P < 0.05 was considered statistically significant.

RESULTS

The results showed that the two groups of intervention and test were identical in terms of demographic information. In the intervention group, before and after 2 months of educational intervention, there was a significant difference in increasing awareness and self-care behavior in diet, physical activity, blood sugar testing, foot care, and medication (P < 0.001). However, this difference was not significant in the control group (P < 0.05). In the intervention group, the mean FBS and quarterly (HbA1c) index decreased significantly (P < 0.05).

CONCLUSION

This study showed that teaching self-care program, in the same way, has been effective in improving self-care behavior and blood sugar index in the elderly with diabetes and suggested that this educational method be used in other chronic diseases.

Self-management Education Program: The Case of Glycemic Control of Type 2 Diabetes

Objectives

Self-management education (SME) is recognized globally as a tool that enables patients to achieve optimal glucose control. While factors influencing the effectiveness of self-management interventions have been studied extensively, the impact of program length on clinical endpoints of patients diagnosed with diabetes is underdeveloped. This paper synthesized information from the existing literature to understand the effect of program length on glycated hemoglobin (HbA_1C) in adults with type 2 diabetes mellitus.

Methods

We searched Web of Science, PubMed, Scopus, MEDLINE, EMBASE, PsychINFO, and the Cochrane Central Register of Controlled Trials to identify relevant English language publications on diabetes self-management education published between January 2000 and April 2019.

Results

The review included 25 randomized controlled trials, with 64.0% reporting significant changes in HbA_1C. The studies classified as long-term (lasting one year and above) were associated with the greatest number of interventions achieving statistically significant (87.5% significant vs. 12.5% non-significant) differences in changes in HbA_1C between the intervention and the control subjects, recording an overall between-group HbA_1C mean difference of 0.6±0.3% (range = 0.2–1.2).

Conclusions

Our findings suggest that program length may change the effectiveness of educational interventions. Achieving sustained improvements in patients’ HbA_1C levels will require long-term, ongoing SME, and support.

Sensorimotor and Cognitive Abilities Associated With Touchscreen Tablet App Performance to Support Self-Management of Type 2 Diabetes

IMPORTANCE

Self-management programs (facilitated by mobile devices) may improve health and prevent secondary complications for older adults with diabetes. However, older adults may have difficulties using mobile devices because of neuropathy or cognitive dysfunction.

OBJECTIVE

To identify sensorimotor and cognitive abilities associated with touchscreen tablet app performance to support self-management of diabetes in older adults.

DESIGN

Cross-sectional study.

SETTING

Outpatient Center for Successful Aging With Diabetes.

PARTICIPANTS

Forty-five older adults with Type 2 diabetes.

OUTCOMES AND MEASURES

Dexterity (Purdue Pegboard Test), touch sensation (Semmes-Weinstein monofilaments), pinch strength (pinch gauge), cognition (Montreal Cognitive Assessment), and executive functioning (Trail Making Test) were assessed. Two apps were then used: Dexteria and SuCare. Demographic data, prior mobile device use, and diabetes severity (hemoglobin A1C [HbA1C]) were collected.

RESULTS

Age and HbA1C accounted for 29.8% and 9.7%, respectively, of the total variance of Dexteria performance time (dominant hand). Dexterity (dominant hand) accounted for an additional 5.4% of the total variance of 45.1%, F(4, 40) = 10.021, p < .001. Prior mobile device use, age, and diabetes severity accounted for 6.4%, 11.8%, and 26.4%, respectively, of the total variance of SuCare performance time. Executive functioning and dominant-hand dexterity accounted for an additional 9.5% and 9.4%, respectively, of the total variance of 61.0%, F(5, 39) = 14.75, p < .001.

CONCLUSIONS AND RELEVANCE

Beyond age and diabetes severity, executive functioning and dominant-hand dexterity contributed to app performance, highlighting the importance of diabetes self-management. These findings may help determine suitable candidates for tablet use for self-management.

WHAT THIS ARTICLE ADDS

App performance is explained by the executive functioning and dexterity of older adults with Type 2 diabetes. These factors, in addition to age and diabetes severity, should be taken into consideration by occupational therapy practitioners in future mobile self-management programs.

Association Between Systolic Blood Pressure and Cardiovascular Inpatient Cost Moderated by Peer-Support Intervention Among Adult Patients With Type 2 Diabetes: A 2-Cohort Study

OBJECTIVES

People with type 2 diabetes and increased systolic blood pressure (SBP) are at high risk of cardiovascular disease (CVD). In this study, we aimed to investigate the association between CVD-related hospital payments and SBP and tested whether this association is influenced by diabetes peer support.

METHODS

Two cohorts comprising people with type 2 diabetes were included in the study. The first cohort comprised 4,704 patients with type 2 diabetes assessed between 2008 and 2009 from 18 general practices in Cambridgeshire and followed up to 2009-2011. The second cohort comprised 1,121 patients with type 2 diabetes from post-trial follow-up data, recruited between 2011 and 2012 and followed up to 2015. SBP was measured at baseline. Inpatient payments for CVD hospitalization within 2 years since baseline was the main outcome. The impact of 1:1, group or combined diabetes peer support and usual care were investigated in the second cohort. Adjusted mean CVD inpatient payments per person were estimated using a 2-part model after adjusting for baseline characteristics.

RESULTS

A "hockey-stick" relationship between baseline SBP and estimated CVD inpatient payment was identified in both cohorts, with a threshold at 133 to 141 mmHg, suggesting increased payments for patients with SBP below and above the threshold. The combined peer-support intervention altered the aforementioned association, with no increased payment with SBP above the threshold, and payment slightly decreased with SBP beyond the threshold.

CONCLUSIONS

SBP maintained between 133 and 141 mmHg is associated with the lowest CVD disease management costs for patients with type 2 diabetes. Combined peer-support intervention could significantly decrease CVD-related hospital payments.

Effect of a nutrition education programme on the metabolic syndrome in type 2 diabetes mellitus patients at a level 5 Hospital in Kenya: "a randomized controlled trial"

BACKGROUND

Type 2 diabetes mellitus (T2D), is a life-threatening condition of global public health concern. It worsens in the presence of the metabolic syndrome (MetS), a complex disorder characterized by co-occurrence of at least three of such factors as hypertension, obesity, dyslipidemia and insulin resistance. However, lifestyle interventions reduce the risk of both MetS and T2D, and nutrition education can empower individuals on the appropriate, lifestyle changes. The aim of the current study was to evaluate the effect of a nutrition education programme, with and without inclusion of peer to peer support, on MetS in T2D patients.

METHODS

This was a randomized controlled trial with two intervention groups and one control. One of the intervention groups involved a nutrition education programme with peer-to-peer support (NEP); the other involved only the education program, while the control received standard care. Each group had 51 participants. The nutrition education programme was conducted for 2 h per week for 8 weeks. In addition, the NEP had weekly peer-to-peer interactions for 8 weeks. All groups had follow-up sessions for 6 months. Data on MetS risk factors as well as food intake patterns and physical activity levels were taken at baseline and at different time points during the study. Analysis of Co-variance and regression were used in the analysis.

RESULTS

The MetS prevalence improved in the NEP (90 to 52%) and NE (86 to 69%), while it worsened in C (88 to 91%). There was improvement in the mean values of the anthropometric parameters in the NEP and NE which worsened in the control group. There was a general improvement in mean values of blood lipids, fasting blood glucose and HbA1c in all the groups, with NEP showing the greatest improvements, followed by NE, except for triglycerides and HDL where the control group had better improvement than the NE. Changes in the anthropometric and metabolic indicators mirrored the changes in food intake patterns and physical activity, where the greatest improvements occurred in the NEP.

CONCLUSIONS

Nutrition education with inclusion of peer to peer support was of clinical benefit in improving metabolic outcomes and reducing MetS in T2DM patients.

From peer-based to peer-led: redefining the role of peers across the hepatitis C care pathway: HepCare Europe

BACKGROUND

HCV infection disproportionately affects underserved populations such as homeless individuals, people who inject drugs and prison populations. Peer advocacy can enable active engagement with healthcare services and increase the likelihood of favourable treatment outcomes.

OBJECTIVES

This observational study aims to assess the burden of disease in these underserved populations and describe the role of peer support in linking these individuals to specialist treatment services.

METHODS

Services were identified if they had a high proportion of individuals with risk factors for HCV, such as injecting drug use or homelessness. Individuals were screened for HCV using point-of-care tests and a portable FibroScan. All positive cases received peer support for linkage to specialist care. Information was gathered on risk factors, demographics and follow-up information regarding linkage to care and treatment outcomes.

RESULTS

A total of 461 individuals were screened, of which 197 (42.7%) were chronically infected with HCV. Referral was made to secondary care for 176 (89.3%) and all received peer support, with 104 (52.8%) individuals engaged with treatment centres. Of these, 89 (85.6%) started treatment and 76 (85.4%) had a favourable outcome. Factors associated with not being approved for treatment were recent homelessness, younger age and current crack cocaine injecting.

CONCLUSIONS

Highly trained peer support workers working as part of a specialist outreach clinical team help to identify a high proportion of individuals exposed to HCV, achieve high rates of engagement with treatment services and maintain high rates of treatment success amongst a population with complex needs.

How patient and community involvement in diabetes research influences health outcomes: A realist review

Background

Patient and public involvement in diabetes research is an international requirement, but little is known about the relationship between the process of involvement and health outcomes.

Objective

This realist review identifies who benefits from different types of involvement across different contexts and circumstances. Search strategies Medline, CINAHL and EMBASE were searched to identify interventions using targeted, embedded or collaborative involvement to reduce risk and promote self‐management of diabetes. People at risk/with diabetes, providers and community organizations with an interest in addressing diabetes were included. There were no limitations on date, language or study type.

Data extraction and synthesis

Data were extracted from 29 projects using elements from involvement frameworks. A conceptual analysis of involvement types was used to complete the synthesis.

Main results

Projects used targeted (4), embedded (8) and collaborative (17) involvement. Productive interaction facilitated over a sufficient period of time enabled people to set priorities for research. Partnerships that committed to collaboration increased awareness of diabetes risk and mobilized people to co‐design and co‐deliver diabetes interventions. Cultural adaptation increased relevance and acceptance of the intervention because they trusted local delivery approaches. Local implementation produced high levels of recruitment and retention, which project teams associated with achieving diabetes health outcomes.

Discussion and Conclusions

Achieving understanding of community context, developing trusting relationships across sectors and developing productive partnerships were prerequisites for designing research that was feasible and locally relevant. The proportion of diabetes studies incorporating these elements is surprisingly low. Barriers to resourcing partnerships need to be systematically addressed.

Derivation and external validation of risk algorithms for cerebrovascular (re)hospitalisation in patients with type 2 diabetes: Two cohorts study

AIMS

Cerebrovascular disease is one of more typical reasons for hospitalisation and re-hospitalisation in people with type 2 diabetes. We aimed to derive and externally validate two risk prediction algorithms for cerebrovascular hospitalisation and re-hospitalisation.

METHODS

Two independent cohorts were used to derive and externally validate the two risk scores. The development cohort comprises 4704 patients with type 2 diabetes registered in 18 general practices across Cambridgeshire. The validation cohort includes 1121 type 2 patients from a post-trial cohort data. Outcomes were cerebrovascular hospitalisation within two years and cerebrovascular re-hospitalisation within ninety days of the previous cerebrovascular hospitalisation. Logistic regression was applied to derive the two risk scores for cerebrovascular hospitalisation and re-hospitalisation from development cohort, which were externally validated in the validation cohort.

RESULTS

The incidence of cerebrovascular hospitalisation and re-hospitalisation was 3.76% and 1.46% in the development cohort, and 4.99% and 1.87% in the external validation cohort. Age, gender, body mass index, blood pressures, and lipid profiles were included in the final model. Model discrimination was similar in both cohorts, with all C-statistics > 0.70, and very good calibration of observed and predicted individual risks.

CONCLUSION

Two new risk scores that quantify individual risks of cerebrovascular hospitalisation and re-hospitalisation have been well derived and externally validated. Both scores are on the basis of a few of clinical measurements that are commonly available for patients with type 2 diabetes in primary care settings and could work as tools to identify individuals at high risk of cerebrovascular hospitalisation and re-hospitalisation.

Total/high density lipoprotein cholesterol and cardiovascular disease (re)hospitalization nadir in type 2 diabetes

Total cholesterol to HDL cholesterol ratio (TC/HDL) is an important prognostic factor for CVD. This study used restricted cubic spline modeling to investigate the dose-response associations between TC/HDL and both CVD hospitalization and CVD rehospitalization in two independent prospective cohorts. The East Cambridgeshire and Fenland cohort includes 4,704 patients with T2D from 18 general practices in Cambridgeshire. The Randomized controlled trial of Peer Support In type 2 Diabetes cohort comprises 1,121 patients with T2D with posttrial follow-up data. TC/HDL and other demographic and clinical measurements were measured at baseline. Outcomes were CVD hospitalization over 2 years and CVD rehospitalization after 90 days of the prior CVD hospitalization. Modeling showed nonlinear relationships between TC/HDL and risks of CVD hospitalization and rehospitalization consistently in both cohorts (all P < 0.001 for linear tests). The lowest risks of CVD hospitalization and rehospitalization were consistently found for TC/HDL at 2.8 (95% CI: 2.6-3.0) in both cohorts and both overall and by gender. This is lower than the current lipid control target, 4.0 of TC/HDL. Reducing the TC/HDL target to 2.8 would include a further 33-44% patients with TC/HDL in the 2.8-4.0 range. Studies are required to assess the effectiveness and cost-effectiveness of the earlier introduction of, and more intensive, lipid-lowering treatment needed to achieve this new lower TC/HDL target.

Impact of peer support on inpatient and outpatient payments among people with Type 2 diabetes: a prospective cohort study

AIM

To investigate the impact of a low-cost diabetes peer-support intervention, aimed at reducing inpatient and outpatient care utilization and healthcare payments, by conducting a cohort study that followed up a randomized controlled trial.

METHODS

A total of 1121 adults with Type 2 diabetes were recruited through general practices in Cambridgeshire and Hertfordshire, UK, and were followed up for 3.25 financial years after 8-12 months of one-to-one, group or combined diabetes peer support and usual care. Use of, and payments for inpatient and outpatient services were fully recorded in the follow-up. Adjusted mean inpatient and outpatient payments per person were estimated using a two-part model after adjusting for baseline characteristics.

RESULTS

The mean age of the recruited adults was 65.6±11.4 years, 60.4% were male, and 16.8% were insulin-treated. Compared with the control group, less healthcare utilization (especially non-elective inpatient care and outpatient consultations) was observed in each of the intervention groups, particularly the combined intervention group. Over the course of 3.25 financial years, significant reductions of 41% (£909.20 per head) were observed for overall inpatient payments (P<0.0001), 51% (£514.67 per head) for non-elective inpatient payments (P=0.005) in the combined intervention group, and 34% (£413.30 per head) and 32% (£388.99 per head) for elective inpatient payments in the one-to-one (P=0.029) and combined intervention (P=0.048) groups, respectively.

CONCLUSIONS

Type 2 diabetes peer support, whether delivered using a one-to-one, group or combined approach was associated with reduced inpatient care utilization (particularly non-elective admissions) and payments over 3.25 years.

Development of a supported self-management intervention for adults with type 2 diabetes and a learning disability

BACKGROUND

Although supported self-management is a well-recognised part of chronic disease management, it has not been routinely used as part of healthcare for adults with a learning disability. We developed an intervention for adults with a mild or moderate learning disability and type 2 diabetes, building on the principles of supported self-management with reasonable adjustments made for the target population.

METHODS

In five steps, we:Clarified the principles of supported self-management as reported in the published literatureIdentified the barriers to effective self-management of type 2 diabetes in adults with a learning disabilityReviewed existing materials that aim to support self-management of diabetes for people with a learning disabilitySynthesised the outputs from the first three phases and identified elements of supported self-management that were (a) most relevant to the needs of our target population and (b) most likely to be acceptable and useful to themImplemented and field tested the intervention.

RESULTS

The final intervention had four standardised components: (1) establishing the participant's daily routines and lifestyle, (2) identifying supporters and their roles, (3) using this information to inform setting realistic goals and providing materials to the patient and supporter to help them be achieved and (4) monitoring progress against goals.Of 41 people randomised in a feasibility RCT, thirty five (85%) completed the intervention sessions, with over three quarters of all participants (78%) attending at least three sessions.Twenty-three out of 40 (58%) participants were deemed to be very engaged with the sessions and 12/40 (30%) with the materials; 30 (73%) participants had another person present with them during at least one of their sessions; 15/41 (37%) were reported to have a very engaged main supporter, and 18/41 (44%) had a different person who was not their main supporter but who was engaged in the intervention implementation.

CONCLUSIONS

The intervention was feasible to deliver and, as judged by participation and engagement, acceptable to participants and those who supported them.

Development and External Validation of Risk Scores for Cardiovascular Hospitalization and Rehospitalization in Patients With Diabetes

CONTEXT

Cardiovascular disease (CVD) is a common and costly reason for hospitalization and rehospitalization among patients with type 2 diabetes.

OBJECTIVE

This study aimed to develop and externally validate two risk-prediction models for cardiovascular hospitalization and cardiovascular rehospitalization.

DESIGN

Two independent prospective cohorts.

SETTING

The derivation cohort includes 4704 patients with type 2 diabetes from 18 general practices in Cambridgeshire. The validation cohort comprises 1121 patients with type 2 diabetes from post-trial follow-up data.

MAIN OUTCOME MEASURE

Cardiovascular hospitalization over 2 years and cardiovascular rehospitalization after 90 days of the prior CVD hospitalization.

RESULTS

The absolute rate of cardiovascular hospitalization and rehospitalization was 12.5% and 6.7% in the derivation cohort and 16.3% and 7.0% in the validation cohort. Discrimination of the models was similar in both cohorts, with C statistics above 0.70 and excellent calibration of observed and predicted risks.

CONCLUSION

Two prediction models that quantify risks of cardiovascular hospitalization and rehospitalization have been developed and externally validated. They are based on a small number of clinical measurements that are available for patients with type 2 diabetes in many developed countries in primary care settings and could serve as the tools to screen the population at high risk of cardiovascular hospitalization and rehospitalization.

Can peer support be cost saving? An economic evaluation of RAPSID: a randomized controlled trial of peer support in diabetes compared to usual care alone in East of England communities

BACKGROUND

Diabetes peer support, where one person with diabetes helps others, may improve diabetes management. The objective of this study was to perform a cost analysis of peer support strategies used in RAndomized controlled trial of Peer Support in type 2 Diabetes.

METHODS

We performed a 2×2 factorial randomized cluster controlled trial in England. People with type 2 diabetes were invited to participate as either 'peer' or 'peer support facilitator' (PSF) through postal invitation predominantly from general practice. Clusters, based on local communities, were each randomly assigned to one arm of group, 1:1, both group and 1:1 or control interventions. The intervention was delivered over 8-12 months by trained PSFs, supported by monthly meetings with a diabetes nurse. Out-of-pocket expenses/service utilization were self-reported at baseline, midpoint and on trial completion. Intervention costs were collated. Non-hospital costs used National Health Service (NHS) reference costs. Hospital payments were obtained from one local commissioning group and mean payments calculated. The analysis employed a societal perspective. Costs were evaluated at the conclusion of the trial.

RESULTS

Participants (n=1299) were recruited across 130 clusters. The four arms were well balanced and matched (60% male, mean diabetes duration 9.5 years, mean glycated haemoglobin (HbA1c) 7.4+/-1.3%, 17% insulin treated). Implementation costs at 2013 rates were £13.84/participant/annum, participant out-of-pocket expenses for any intervention were £11.41/participant/annum and the NHS-incurred costs were reduced by £138.38/participant/annum. Savings for the 1:1, group and any intervention were £233.65, £90.52 and £113.13/participant/annum, respectively.

CONCLUSIONS

We conclude that both 1:1 and group diabetes peer support over 8-12 months are cost saving in this setting, although much of the benefit is largely derived by differences in self-reported healthcare utilization. Long-term benefits should be investigated.

The relationship between diabetes attitudes and treatment among free clinic patients and volunteers

Free clinics provide free primary care to the under or uninsured and have been playing an important role in serving the socio-economically disadvantaged. Free clinic patients represent a group of people who experience significant barriers to receiving diabetes prevention and intervention. This study examined diabetes attitudes among free clinic patients and volunteers. English or Spanish speaking patients and volunteers (N = 384), aged 18 years or older completed a self-administered survey. Diabetic patients and volunteers shared similar levels of diabetes attitudes compared to non-diabetic patients. Among patients, ethnicity, education level, diabetes education, and family history affected diabetes attitudes. Among volunteers, diabetes education was an important factor associated with positive diabetes attitudes. Whether the volunteer is a healthcare professional or student was related only to one aspect of diabetes attitudes, seriousness of type 2 diabetes. The results, indicating free clinic diabetic patients and volunteers shared similar levels of diabetes attitudes, were positive for maintaining and developing diabetes education programs at a free clinic. Unfortunately, the average length of volunteering at this free clinic was short and student volunteers likely leave the clinic upon graduation. Future research should examine issues of volunteer retention in free clinics. Diabetes education for patients may need to be diversified according to ethnicity, family history of diabetes, and educational level. Finally, non-healthcare professional volunteers could potentially be involved in diabetes education at a free clinic.

A Comprehensive Lifestyle Peer Group-Based Intervention on Cardiovascular Risk Factors: The Randomized Controlled Fifty-Fifty Program

BACKGROUND

Cardiovascular diseases stem from modifiable risk factors. Peer support is a proven strategy for many chronic illnesses. Randomized trials assessing the efficacy of this strategy for global cardiovascular risk factor modification are lacking.

OBJECTIVES

This study assessed the hypothesis that a peer group strategy would help improve healthy behaviors in individuals with cardiovascular risk factors.

METHODS

A total of 543 adults 25 to 50 years of age with at least 1 risk factor were recruited; risk factors included hypertension (20%), overweight (82%), smoking (31%), and physical inactivity (81%). Subjects were randomized 1:1 to a peer group-based intervention group (IG) or a self-management control group (CG) for 12 months. Peer-elected leaders moderated monthly meetings involving role-play, brainstorming, and activities to address emotions, diet, and exercise. The primary outcome was mean change in a composite score related to blood pressure, exercise, weight, alimentation, and tobacco (Fuster-BEWAT score, 0 to 15). Multilevel models with municipality as a cluster variable were applied to assess differences between groups.

RESULTS

Participants' mean age was 42 ± 6 years, 71% were female, and they had a mean baseline Fuster-BEWAT score of 8.42 ± 2.35. After 1 year, the mean scores were significantly higher in the IG (n = 277) than in the CG (n = 266) (IG mean score: 8.84; 95% confidence interval (CI): 8.37 to 9.32; CG mean score: 8.17; 95% CI: 7.55 to 8.79; p = 0.02). The increase in the overall score was significantly larger in the IG compared with the CG (difference: 0.75; 95% CI: 0.32 to 1.18; p = 0.02). The mean improvement in the individual components was uniformly greater in the IG, with a significant difference for the tobacco component.

CONCLUSIONS

The peer group intervention had beneficial effects on cardiovascular risk factors, with significant improvements in the overall score and specifically on tobacco cessation. A follow-up assessment will be performed 1 year after the final assessment reported here to determine long-term sustainability of the improvements associated with peer group intervention.

Challenges in the Ethical Review of Peer Support Interventions

PURPOSE

Ethical review processes have become increasingly complex. We have examined how 8 collaborating diabetes peer-support clinical trials were assessed by ethics committees.

METHODS

The ethical reviews from the 8 peer-support studies were collated and subjected to a thematic analysis. We mapped the recommendations of local Institutional Review Boards and ethics committees onto the "4+1 ethical framework" (autonomy, beneficence, non-maleficence, and justice, along with concern for their scope of application).

RESULTS

Ethics committees did not consistently focus on tasks within the 4+1 framework: many conducted reviews of scientific, organizational, and administrative activities. Of the 20 themes identified across the ethical reviews, only 4 fell within the scope of the 4+1 framework. Variation in processes and requirements for ethics committees were particularly evident between study countries. Some of the consent processes mandated by ethical review boards were disproportionate for peer support, increased participant burden, and reduced the practicality of testing an ethical intervention. Across the 8 studies, ethics committees' reviews included the required elements to ensure participant safety; however, they created a range of hurdles that in some cases delayed the research and required consent processes that could hinder the spontaneity and/or empathy of peer support.

CONCLUSION

Ethics committees should avoid repeating the work of other trusted agencies and consider the ethical validity of "light touch" consent procedures for peer-support interventions. The investigators propose an ethical framework for research on peer support.

Impact of community based peer support in type 2 diabetes: a cluster randomised controlled trial of individual and/or group approaches

Background

Diabetes peer support, where one person with diabetes helps guide and support others, has been proposed as a way to improve diabetes management. We have tested whether different diabetes peer support strategies can improve metabolic and/or psychological outcomes.

Methods

People with type 2 diabetes (n = 1,299) were invited to participate as either ‘peer’ or ‘peer support facilitator’ (PSF) in a 2x2 factorial randomised cluster controlled trial across rural communities (130 clusters) in England. Peer support was delivered over 8–12 months by trained PSFs, supported by monthly meetings with a diabetes educator. Primary end point was HbA1c. Secondary outcomes included quality of life, diabetes distress, blood pressure, waist, total cholesterol and weight. Outcome assessors and investigators were masked to arm allocation. Main factors were 1:1 or group intervention. Analysis was by intention-to-treat adjusting for baseline.

Results

The 4 arms were well matched (Group n = 330, 1:1(individual) n = 325, combined n = 322, control n = 322); 1035 (79•7%) completed the mid-point postal questionnaire and 1064 (81•9%) had a final HbA1c. A limitation was that although 92.6% PSFs and peers were in telephone contact, only 61.4% of intervention participants attended a face to face session. Mean baseline HbA1c was 57 mmol/mol (7•4%), with no significant change across arms. Follow up systolic blood pressure was 2•3mm Hg (0.6 to 4.0) lower among those allocated group peer-support and 3•0mm Hg (1.1 to 5.0) lower if the group support was attended at least once. There was no impact on other outcomes by intention to treat or significant differences between arms in self-reported adherence or medication.

Conclusions

Group diabetes peer support over 8–12 months was associated with a small improvement in blood pressure but no other significant outcomes. Long term benefits should be investigated.

Emotional support for diabetes management: an international cross-cultural study

PURPOSE

The purpose of this study was to explore how emotional support emerged in interactions between peer supporters (PSs) and adults living with type 2 diabetes.

METHODS

Qualitative data were analyzed from 22 semistructured interviews with PSs in 3 settings: low-income Latinos in Chicago, middle-class Caucasians in the United Kingdom, and low-income African American women in North Carolina. Emotional support was defined as expressions of empathy, trust, and caring.

RESULTS

Across all sites, emotional support gradually emerged over time, was often combined with informational support, and was conveyed both implicitly (through nonverbal actions connoting emotional acceptance; eg, a walk together without discussion of problems) and explicitly (eg, by reassurance or discussion of stressors). Cross-site differences did appear regarding the strategies to address barriers to diabetes management (eg, PSs in North Carolina and Chicago reported providing support for social stressors) and the role of PSs (eg, PSs in Chicago reported providing directive support).

CONCLUSIONS

Across different settings and populations, emotional support for diabetes management evolved over time, was often integrated with informational support, and emerged through both implicit and explicit strategies that addressed varied context-specific stressors.

Increasing capacity to deliver diabetes self-management education: results of the DESMOND lay educator non-randomized controlled equivalence trial

AIM

To develop and test a format of delivery of diabetes self-management education by paired professional and lay educators.

METHODS

We conducted an equivalence trial with non-randomized participant allocation to a Diabetes Education and Self Management for Ongoing and Newly Diagnosed Type 2 diabetes (DESMOND) course, delivered in the standard format by two trained healthcare professional educators (to the control group) or by one trained lay educator and one professional educator (to the intervention group). A total of 260 people with Type 2 diabetes diagnosed within the previous 12 months were referred for self-management education as part of routine care and attended either a control or intervention format DESMOND course. The primary outcome measure was change in illness coherence score (derived from the Diabetes Illness Perception Questionnaire-Revised) between baseline and 4 months after attending education sessions. Secondary outcome measures included change in HbA1c level. The trial was conducted in four primary care organizations across England and Scotland.

RESULTS

The 95% CI for the between-group difference in positive change in coherence scores was within the pre-set limits of equivalence (difference = 0.22, 95% CI 1.07 to 1.52). Equivalent changes related to secondary outcome measures were also observed, including equivalent reductions in HbA1c levels.

CONCLUSION

Diabetes education delivered jointly by a trained lay person and a healthcare professional educator with the same educator role can provide equivalent patient benefits. This could provide a method that increases capacity, maintains quality and is cost-effective, while increasing access to self-management education.

Assessment of implementation fidelity in diabetes self-management education programs: a systematic review

OBJECTIVE

As diabetes requires extensive self-care, self-management education is widely recommended to enhance the effectiveness and reduce the costs of treatment. While a variety of diabetes self-management (DSM) programs are available, the conditions for their effective implementation are not well documented. This paper reviews the literature on implementation fidelity (IF), the degree to which programs are delivered as intended, as a factor influencing the effectiveness of diabetes education.

METHODS

Medical, psychological and educational research databases were searched to identify published studies on diabetes education describing the implementation process. Studies detailing the intervention adherence/fidelity/integrity were included to assess the way key elements of IF were addressed.

RESULTS

From an initial 418 abstracts, 20 published papers were retained for an in-depth analysis focusing on the components of IF. Intervention content was mainly assessed through observation, whereas intervention dose was more often assessed through self-report measures. Only one study addressed the relationship between IF and intervention effectiveness.

CONCLUSION

Despite the importance of IF to achieve program outcomes, IF of DSM programs remains largely under-investigated.

PRACTICE IMPLICATIONS

The results of this review suggest that reports on DSM education should systematically describe how the program was implemented. The impact of IF on program outcomes needs further investigation.

Peer educator vs. respiratory therapist support: which form of support better maintains health and functional outcomes following pulmonary rehabilitation?

OBJECTIVE

This study examined if ongoing support delivered by telephone following pulmonary rehabilitation (PR) assisted chronic obstructive pulmonary disease (COPD) patients to maintain health outcomes.

METHODS

Phase one (n=79) compared post-rehabilitation telephone-based support delivered by peers compared to usual care (UC). The second phase (n=168) compared post-rehabilitation support from peer educators, respiratory therapists (RT), or UC. Primary outcome variables were St. George's Respiratory Questionnaire (SGRQ) total score and the six minute walk test (6MWT). Measures were obtained at baseline, immediately following PR, and six-months post PR.

RESULTS

Six-month follow-up data for phase one was collected for 66 COPD patients (n=35 peer support, n=31 UC) and 142 for phase two (n=42 peer support, n=52 RT support, n=48 UC). Per-protocol and intention to treat (ITT) analysis in both phases found no significant group by time differences for SGRQ or 6MWT.

CONCLUSION

Providing peer or RT support via telephone following PR was not more effective than UC for maintaining health outcomes.

PRACTICE IMPLICATIONS

There are concerns with using peers to provide ongoing support to COPD patients. Additionally, COPD patients require a higher level of care than telephone support can provide.
