Key Features Of Peer Support In Chronic Disease Prevention And Management

Peer characteristics associated with improved glycemic control in a randomized controlled trial of a reciprocal peer support program for diabetes

OBJECTIVE

In a secondary analysis of a randomized controlled trial of diabetes reciprocal peer support, we examined characteristics of peers associated with improvements in their partner's glycemic control.

METHODS

A total of 102 adults with diabetes were randomized to the reciprocal peer support arm (vs. a nurse care management arm). The primary outcome was change in A1c over six months. Intermediate outcomes were insulin initiation and peer engagement. A number of baseline characteristics of peers were hypothesized to influence outcomes for their peer, and concordant characteristics of peer dyads were hypothesized that would influence outcomes for both peer partners.

RESULTS

Improvement in A1c was associated with having a peer older than oneself ( P < .05) or with higher diabetes-related distress ( P < .01). Participants with peers who reported poorer health at baseline had worse glycemic control at follow-up ( P < .01). Hypothesized concordant characteristics were not associated with A1c improvements. Participants whose peers had a more controlled self-regulation style were more likely to initiate insulin ( P < .05).

DISCUSSION

The improved outcomes of peers whose partners were older and reported more diabetes distress at baseline supports the need for further research into the peer characteristics that lead to improved outcomes. This could allow for better matching and more effective partnerships.

Contextualizing Experiences of Diabetes-Related Stress in Rural Dominican Republic

Type 2 diabetes (T2D) is changing the burden of disease across Latin America. In this formative, qualitative study, we explored experiences of T2D diagnosis and management among adults in rural Dominican Republic. We conducted 28 in-depth interviews (12 men, 16 women) and used inductive analysis to explore the emotional burden of T2D and identify coping strategies. We found that stress relating to T2D began at diagnosis and persisted throughout management. Stress was produced by concerns about healthy food and medication access, fears about illness-induced injury, and the cyclical process of experiencing stress. Participants identified diabetes care and free medication services as external stress-reducers. Internally, participants' mitigated stress by not thinking about diabetes (" no dar mente"). Our study highlights the importance of a contextualized understanding of diabetes-related stress and the need for individual, clinic, and community-level interventions to reduce stressors and improve health outcomes among adults with T2D.

Effectiveness of Technologically Enhanced Peer Support in Improving Glycemic Management Among Predominantly African American, Low-Income Adults With Diabetes

PURPOSE

The purpose of the study was to examine whether a peer coaching intervention is more effective in improving clinical outcomes in diabetes when enhanced with e-health educational tools than peer coaching alone.

METHODS

The effectiveness of peer coaches who used an individually tailored, interactive, web-based tool (iDecide) was compared with peer coaches with no access to the tool. Two hundred and ninety Veterans Affairs patients with A1C ≥8.0% received a 6-month intervention with an initial session with a fellow patient trained to be a peer coach, followed by weekly phone calls to discuss behavioral goals. Participants were randomized to coaches who used iDecide or coaches who used nontailored educational materials at the initial session. Outcomes were A1C (primary), blood pressure, and diabetes social support (secondary) at 6 and 12 months.

RESULTS

Two hundred and fifty-five participants (88%) completed 6-month and 237 (82%) 12-month follow-up. Ninety-eight percent were men, and 63% were African American. Participants in both groups improved A1C values (>-0.6%, P < .001) at 6 months and maintained these gains at 12-month follow-up ( >-0.5%, P < .005). Diabetes social support was improved at both 6 and 12 months ( P < .01). There were no changes in blood pressure.

CONCLUSIONS

Clinical gains achieved through a volunteer peer coach program were not increased by the addition of a tailored e-health educational tool.

Evaluation of a program to improve intermediate diabetes outcomes in rural communities in the Dominican Republic

AIMS

To describe implementation of diabetes and hypertension program in rural Dominican Republic (DR), and report six years of quality improvement process and health outcomes.

METHODS

Dominican teams at two clinics are supported by Chronic Care International with: supervision and continuing education, electronic database, diabetes and hypertension protocols, medications, self-management education materials, behavior change techniques, and equipment and testing supplies (e.g., HbA1c, lipids, blood pressure, BMI). A monthly dashboard for care processes and health outcomes guides problem solving and goal setting. Results were analyzed for quality improvement reports and by fitting the clinical data to random-effects linear models.

RESULTS

1191 adults were enrolled in the program at two clinics (44% men, baseline means: 56.4 years, BMI 27.4 kg/m², HbA1c 8.8% (73 mmol/mol), BP 133/81 mmHg). Data show steady growth in clinic populations reaching capacity. Protocols for comprehensive foot examinations, BP and HbA1c assessments, and proportions reaching quality measures improved over time, especially after clinic goal setting. Modeling of BP, BMI and HbA1c values revealed important differences in outcomes by clinic over time.

CONCLUSIONS

Improvements in process and health outcomes are attainable in rural DR when medical teams have support and access to data. Scalability and sustainability are continuing goals.

Effect of peer support on health outcomes in patients with cardiac pacemaker implantation: A randomized, controlled trial

The aim of this study was to examine the effect of a nurse-led telephone-based peer support program on health outcomes in patients after cardiac pacemaker implantation. Seventy six patients who received cardiac pacemaker implantation were recruited as participants and randomly assigned to either the peer support group or the usual care group. The usual care group received routine care and health education measures provided by nurses; the peer support group received telephone-based peer support. Health-related quality of life, self-care knowledge-attitudes-practice, postoperative anxiety and depression, compliance with attending scheduled follow-up visits, and the incidence of postoperative complications were evaluated at baseline and 6 months' postintervention for the two groups. The result showed that the interventions had a better effect on self-care knowledge-attitudes-practice, postoperative anxiety and depression, and compliance with attending scheduled follow-up visits in the peer support group than in the usual care group. This study confirms that telephone-based peer support improves self-care ability, compliance with attending scheduled follow-up visits, and reduces postoperative anxiety and depression more effectively than conventional nurse care among patients with cardiac pacemaker implantation.

Developing Methods That Facilitate Coding and Analysis of Synchronous Conversations via Virtual Environments

Programs via the Internet are uniquely positioned to capture qualitative data. One reason is because the Internet facilitates the creation of a community of similar individuals who can exchange information and support related to living with a chronic illness. Synchronous conversations via the Internet can provide insight into real-time social interaction and the exchange of social support. One way to analyze interactions among individuals is by using qualitative methods such as content, conversation, or discourse analysis. This manuscript describes how we used content analysis with aspects from conversation and discourse analysis to analyze synchronous conversations via the Internet to describe what individuals talk about and how individuals talk in an Internet-mediated interaction. With the increase in Internet interventions that facilitate collection of real-time conversational data, this article provides insight into how combining qualitative methods can facilitate the coding and analysis of these complex data.

Peer support opportunities across the cancer care continuum: a systematic scoping review of recent peer-reviewed literature

OBJECTIVE

Evidence suggests peer support (PS) is as an effective strategy for enhancing prevention and control of chronic and infectious diseases, including cancer. This systematic scoping review examines the range and variety of interventions on the use of PS across the cancer care continuum.

METHOD

We used a broad definition of PS to capture a wide-range of interventions and characterize the current status of the field. Literature searches were conducted using PubMed, SCOPUS, and CINAHL to identify relevant articles published from January 2011 to June 2016. We screened the title and abstracts of 2087 articles, followed by full-text screening of 420 articles, resulting in a final sample of 242 articles of which the most recent 100 articles were reviewed (published June 2014 to May 2016).

RESULTS

A number of the recent intervention studies focused on breast cancer (32%, breast cancer only) or multiple cancer sites (23%). Although the interventions spanned all phases of the cancer care continuum, only 2% targeted end-of-life care. Seventy-six percent focused on clinical outcomes (e.g., screening, treatment adherence) and 72% on reducing health disparities. Interventions were primarily phone-based (44%) or delivered in a clinic setting (44%). Only a few studies (22%) described the impact of providing PS on peer supporters.

CONCLUSION

PS appears to be a widely used approach to address needs across the cancer care continuum, with many opportunities to expand its reach.

Mental Health in China: Stigma, Family Obligations, and the Potential of Peer Support

Some people with mental illness in China do not receive treatment. We explored how stigma and familial obligation influenced accessibility of social support for patients with depression in China and the potential acceptability of peer support programs. Semi-structured qualitative interviews were conducted with five psychiatrists and 16 patients receiving care for depression from a large psychiatric hospital in Jining, Shandong Province of China. Patients with mental illness reported barriers that prevented them from (a) receiving treatment and (b) relying on informal social support from family members, including stigma, somatization, and community norms. Circumventing these barriers, peer support (i.e., support from others with depression) was viewed by patients as an acceptable means of exchanging information and relying on others for support. Formative research on peer support programs to examine programming and activities may help reduce the burden of unmet mental health care needs in China.

When support is needed: Social support solicitation and provision in an online alcohol use disorder forum

Background

Obtaining adequate social support presents a challenge for many in addiction recovery. Increasingly, individuals in recovery use online forums to exchange support with peers, yet it is unclear which help-seeking strategies most effectively recruit peer support, and which forms of support are most valued by recipients.

Methods

This study applied quantitative content analysis to examine social support solicitation and delivery in an online forum for alcohol use disorder (AUD). We compared the frequency with which peers provided informational, emotional, and companionship support after solicitations that: (1) were direct or indirect, (2) disclosed positive or negative emotions, and (3) mentioned or did not mention recovery problems. We assessed likelihood that recipients would express gratitude after receiving each type of support, and assessed whether the “match” between solicitation and disclosure styles influenced rates of gratitude expression.

Results

Emotional disclosures, whether positive or negative, received the highest volume of supportive replies. Emotional support was the most common response to solicitations overall, and was disproportionately offered after recipients disclosed positive emotions. Informational support was disproportionately offered after recipients disclosed negative emotions or recovery problems, or explicitly requested help. Regardless of their solicitation style, recipients expressed more gratitude after receiving emotional support than other support types.

Conclusions

Providing emotional support was common in an online AUD forum, and precipitated expressing gratitude from recipients to support providers. The results may be helpful in guiding participants to more effectively obtain and provide recovery support in online forums.

Types and sources of social support among adults living with type 2 diabetes in rural communities in the Dominican Republic

Type 2 diabetes management hinges on various determinants, including the role of interpersonal relationships in self-management behaviours. The aim of this study was to explore the types and sources of social support received by adults in the diabetes diagnosis and self-management processes. We conducted qualitative interviews with 28 men and women at two rural clinics in the Dominican Republic and used a combination of narrative and thematic analytic techniques to identify key sources and types of social support in their diabetes experiences. Participants described three stages in their diabetes experience: diagnosis, programme-enrolment, and long-term management. During diabetes diagnosis, most participants described receiving no support. At the programme-enrolment stage, friends and neighbours frequently provided informational or instrumental support to get to the clinic. In long-term management, cohabiting partners provided the most support, which was often assistance with their diet. Our findings highlight he need to assess and leverage distinct types and sources of social support at different stages of the diabetes experience.

Peer support to improve diabetes care: an implementation evaluation of the Australasian Peers for Progress Diabetes Program

BACKGROUND

Several studies have now demonstrated the benefits of peer support in promoting diabetes control. The aim of this study is to evaluate the implementation of a cluster randomised controlled trial of a group-based, peer support program to improve diabetes self-management and thereby, diabetes control in people with Type 2 Diabetes in Victoria, Australia.

METHODS

The intervention program was designed to address four key peer support functions i.e. 1) assistance in daily management, 2) social and emotional support, 3) regular linkage to clinical care, and 4) ongoing and sustained support to assist with the lifelong needs of diabetes self-care management. The intervention participants attended monthly group meetings facilitated by a trained peer leader for 12 months. Data was collected on the intervention's reach, participation, implementation fidelity, groups' effectiveness and participants' perceived support and satisfaction with the intervention. The RE-AIM and PIPE frameworks were used to guide this evaluation.

RESULTS

The trial reached a high proportion (79%) of its target population through mailed invitations. Out of a total of 441 eligible individuals, 273 (61.9%) were willing to participate. The intervention fidelity was high (92.7%). The proportion of successful participants who demonstrated a reduction in 5 years cardiovascular disease risk score was 65.1 and 44.8% in the intervention and control arm respectively. Ninety-four percent (94%) of the intervention participants stated that the program helped them manage their diabetes on a day to day basis. Overall, attending monthly group meetings provided 'a lot of support' to 57% and 'moderate' support to 34% of the participants.

CONCLUSION

Peer support programs are feasible, acceptable and can be used to supplement treatment for patients motivated to improve behaviours related to diabetes. However, program planners need to focus on the participation component in designing future programs. The use of two evaluation frameworks allowed a comprehensive evaluation of the trial from the provider-, participant- and public health perspective. The learnings gained from this evaluation will guide and improve future implementation by improving program feasibility for adoption and acceptability among participants, and will ultimately increase the likelihood of program effectiveness for the participants.

The association of depression and diabetes across methods, measures, and study contexts

Background

Empirical research has revealed a positive relationship between type 2 diabetes mellitus and depression, but questions remain regarding timing of depression measurement, types of instruments used to measure depression, and whether “depression” is defined as clinical depression or depressive symptoms. The present study sought to establish the robustness of the depression-diabetes relationship across depression definition, severity of depressive symptoms, recent depression, and lifetime depression in a nationally representative dataset and a large rural dataset.

Methods

The present examination, conducted between 2014 and 2015, used two large secondary datasets: the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2008 (n = 3072) and the Arthritis, Coping, and Emotion Study (ACES) from 2002 to 2006 (n = 2300). Depressive symptoms in NHANES were measured using the Patient Health Questionnaire 9-item survey (PHQ-9). ACES used the Center for Epidemiologic Studies—Depression Scale (CES-D) to measure depressive symptoms and the Composite International Diagnostic Interview (CIDI) to measure diagnosable depression. Diabetes was modelled as the dichotomous outcome variable (presence vs. absence of diabetes). Logistic regression was used for all analyses, most of which were cross-sectional. Analyses controlled for age, ethnicity, sex, education, and body mass index, and NHANES analyses used sample weights to account for the complex survey design. Additional analyses using NHANES data focused on the addition of health behavior variables and inflammation to the model.

Results

NHANES. Every one-point increase in depressive symptoms was associated with a 5% increase in odds of having diabetes [OR: 1.05 (CI: 1.03, 1.07)]. These findings persisted after controlling for health behaviors and inflammation. ACES. For every one-point increase in depressive symptom score, odds of having diabetes increased by 2% [OR: 1.02 (CI: 1.01, 1.03)]. Recent (past 12 months) depression [OR: 1.49, (CI: 1.03, 2.13)] and lifetime depression [OR: 1.40 (CI: 1.09, 1.81)] were also significantly associated with having diabetes.

Conclusions

This study provides evidence for the robustness of the relationship between depression or depressive symptoms and diabetes and demonstrates that depression occurring over the lifetime can be associated with diabetes just as robustly as that which occurs more proximal to the time of study measurement.

Self-care difficulties and reliance on support among vulnerable middle-aged and older adults with chronic conditions: A cross-sectional study

OBJECTIVES

Chronic conditions are pervasive among middle-aged and older adults. This study identified: (1) factors associated with participants reporting difficulties self-managing their chronic condition(s); and (2) factors associated with participants' reliance on external sources for ongoing help and support to improve their health and manage their health conditions.

STUDY DESIGN

Cross-sectional data were collected using the National Council on Aging Chronic Care Survey, a nationally representative telephone survey of adults aged 45 years and older with at least one chronic condition.

MAIN OUTCOME MEASURES

Self-care difficulties among middle-aged and older adults with one or more chronic conditions and factors associated with reliance on ongoing help and support were examined.

RESULTS

Among 731 middle-aged and older adults with one or more chronic conditions, 31% of participants reported their health condition(s) made it difficult for them to care for themselves. Participants who were Hispanic (OR=3.08, P=0.009), had three or more chronic conditions (OR=3.05, P <0.001), took more medications daily (OR=1.07, P=0.046), and experienced certain healthcare-related frustrations (P≤0.023) were more likely to report difficulties self-managing their chronic condition(s). Participants relied on healthcare providers (40%), friends/relatives (20%), internet (9%), people with similar problems (6%), and community groups (3%) for help and support. Reliance on sources of support varied with participants' sociodemographic factors as well as healthcare and medication use.

CONCLUSIONS

Simultaneously considering patients' disease profiles, patient characteristics, difficulties managing their chronic conditions at home, and interactions with the healthcare system can inform tailored approaches and strategies to enhance patient education and resource identification, and can support service linkages.

Peer support of complex health behaviors in prevention and disease management with special reference to diabetes: systematic reviews

OBJECTIVES

Examine Peer Support (PS) for complex, sustained health behaviors in prevention or disease management with emphasis on diabetes prevention and management.

DATA SOURCES AND ELIGIBILITY

PS was defined as emotional, motivational and practical assistance provided by nonprofessionals for complex health behaviors. Initial review examined 65 studies drawn from 1442 abstracts identified through PubMed, published 1/1/2000-7/15/2011. From this search, 24 reviews were also identified. Extension of the search in diabetes identified 30 studies published 1/1/2000-12/31/2015.

RESULTS

In initial review, 54 of all 65 studies (83.1%) reported significant impacts of PS, 40 (61.5%) reporting between-group differences and another 14 (21.5%) reporting significant within-group changes. Across 19 of 24 reviews providing quantifiable findings, a median of 64.5% of studies reviewed reported significant effects of PS. In extended review of diabetes, 26 of all 30 studies (86.7%) reported significant impacts of PS, 17 (56.7%) reporting between-group differences and another nine (30.0%) reporting significant within-group changes. Among 19 of these 30 reporting HbA1c data, average reduction was 0.76 points. Studies that did not find effects of PS included other sources of support, implementation or methodological problems, lack of acceptance of interventions, poor fit to recipient needs, and possible harm of unmoderated PS.

CONCLUSIONS

Across diverse settings, including under-resourced countries and health care systems, PS is effective in improving complex health behaviors in disease prevention and management including in diabetes.

New directions for diabetes prevention and management in behavioral medicine

Accelerating diabetes rates have resulted in a global public health epidemic. Lifestyle change is a cornerstone of care, yet regimen demands may result in adherence difficulties. Distress, depression, and other psychosocial concerns are higher in those with diabetes. While interventions, such as the Diabetes Prevention Program appear to be effective, further research is needed to support the translation of interventions to prevent diabetes. Studies assessing optimal approaches to promoting effective decision making, coping and adherence are needed. More information is needed to evaluate the influence and potential of emerging technologies on intervention delivery and quality of life in children and adults with diabetes. Theoretically informed, interdisciplinary studies that consider ecological models are needed to develop a roadmap for policies and diabetes management recommendations. Reduction of diabetes-related health disparities is a critical area for future studies. Behavioral medicine scientists and practitioners are poised to address these and other proposed future research directions to advance diabetes prevention and management.

A randomized clinical trial of a culturally responsive intervention for African American women with asthma

BACKGROUND

Few interventions have focused on the difficulties that African American women face when managing asthma.

OBJECTIVE

To evaluate a telephone-based self-regulation intervention that emphasized African American women's management of asthma in a series of 6 sessions.

METHODS

A total of 422 African American women with persistent asthma were randomly assigned to either an intervention or control group receiving usual care. Behavioral factors, symptoms and asthma control, asthma-related quality of life, and health care use at baseline and 2 years after baseline were assessed. Generalized estimating equations were used to assess the long-term effect of the intervention on outcomes.

RESULTS

Compared with the control group, those who completed the full intervention (6 sessions) had significant gains in self-regulation of their asthma (B estimate, 0.73; 95% CI, 0.17-1.30; P < .01), noticing changes to their asthma during their menstrual cycle (B estimate, 1.42; 95% CI, 0.69-2.15; P < .001), and when having premenstrual syndrome (B estimate, 1.70; 95% CI, 0.67-2.72; P < .001). They also had significant reductions in daytime symptoms (B estimate, -0.15; 95% CI, -0.27 to -0.03; P < .01), asthma-related hospitalization (B estimate, 0.51; 95% CI, 0.00-1.02; P < .05), and improved asthma control (B estimate, 1.34; 95% CI, 0.57-2.12; P < .001). However, neither grouped changed over time in outcomes.

CONCLUSION

Despite high comorbidity, African American women who completed a culturally responsive self-management program had improvements in asthma outcomes compared with the control group. Future work should address significant comorbidities and psychosocial issues alongside asthma management to improve asthma outcomes in the long term.

A Qualitative Study of How Health Coaches Support Patients in Making Health-Related Decisions and Behavioral Changes

PURPOSE

Although health coaches are a growing resource for supporting patients in making health decisions, we know very little about the experience of health. We undertook a qualitative study of how health coaches support patients in making decisions and implementing changes to improve their health.

METHODS

We conducted 6 focus groups (3 in Spanish and 3 in English) with 25 patients and 5 friends or family members, followed by individual interviews with 42 patients, 17 family members, 17 health coaches, and 20 clinicians. Audio recordings were transcribed and analyzed by at least 2 members of the study team in ATLAS.ti using principles of grounded theory to identify themes and the relationship between them.

RESULTS

We identified 7 major themes that were related to each other in the final conceptual model. Similarities between health coaches and patients and the time health coaches spent with patients helped establish the health coach-patient relationship. The coach-patient relationship allowed for, and was further strengthened by, 4 themes of key coaching activities: education, personal support, practical support, and acting as a bridge between patients and clinicians.

CONCLUSIONS

We identified a conceptual model that supports the development of a strong relationship, which in turn provides the basis for effective coaching. These results can be used to design health coach training curricula and to support health coaches in practice.

Cardiovascular risk outcome and program evaluation of a cluster randomised controlled trial of a community-based, lay peer led program for people with diabetes

Background

The 2013 Global Burden of Disease Study demonstrated the increasing burden of diabetes and the challenge it poses to the health systems of all countries. The chronic and complex nature of diabetes requires active self-management by patients in addition to clinical management in order to achieve optimal glycaemic control and appropriate use of available clinical services. This study is an evaluation of a “real world” peer support program aimed at improving the control and management of type 2 diabetes (T2DM) in Australia.

Methods

The trial used a randomised cluster design with a peer support intervention and routine care control arms and 12-month follow up. Participants in both arms received a standardised session of self-management education at baseline. The intervention program comprised monthly community-based group meetings over 12 months led by trained peer supporters and active encouragement to use primary health care and other community resources and supports related to diabetes. Clinical, behavioural and other measures were collected at baseline, 6 and 12 months. The primary outcome was the predicted 5 year cardiovascular disease risk using the United Kingdom Prospective Diabetes Study (UKPDS) Risk Equation at 12 months. Secondary outcomes included clinical measures, quality of life, measures of support, psychosocial functioning and lifestyle measures.

Results

Eleven of 12 planned groups were successfully implemented in the intervention arm. Both the usual care and the intervention arms demonstrated a small reduction in 5 year UKPDS risk and the mean values for biochemical and anthropometric outcomes were close to target at 12 months. There were some small positive changes in self-management behaviours.

Conclusions

The positive changes in self-management behaviours among intervention participants were not sufficient to reduce cardiovascular risk, possibly because approximately half of the study participants already had quite well controlled T2DM at baseline. Future research needs to address how to enhance community based programs so that they reach and benefit those most in need of resources and supports to improve metabolic control and associated clinical outcomes.
