Case study of an adaptation and implementation of a Diabetes Prevention Program for individuals with serious mental illness

Co-development of implementation strategies to assist staff of a mental health community managed organisation provide preventive care for health behaviours

ISSUE ADDRESSED

People with a mental health condition are at risk of developing chronic physical disease due to smoking tobacco, inadequate nutrition, high alcohol consumption, low physical activity and poor sleep (SNAPS). Community managed organisations (CMOs) represent an opportune setting to support mental health consumers to improve their health behaviours through providing preventive care. Reporting of methods used to co-develop implementation strategies to assist CMO staff to deliver preventive care for SNAPS are scarce yet warranted.

OBJECTIVES

This study aims to: (1) describe a co-development workshop involving CMO staff and researchers to identify preferred implementation support strategies to help staff routinely provide preventive care; (2) describe the strategies that emerged from the workshop; and (3) report staff ratings of the workshop on four co-development principles.

METHODS

A three-hour co-development workshop was conducted on two occasions with staff of one CMO in New South Wales, Australia. Twenty staff participated in the workshops.

RESULTS

Participants generated and ranked a total of seven discrete implementation strategies within five categories (training, point of care prompts, guidelines, continuous quality improvement and consumer activation). Training for staff to have difficult conversations about behaviour change was ranked highest in both workshops. Participants rated the workshops positively across four co-development principles.

CONCLUSIONS

The co-development workshop enabled implementation strategies to be developed within the context in which they were to be delivered and tested, potentially increasing their feasibility, acceptability, appropriateness and impact. SO WHAT?: Implementation strategies selected from the workshops will inform a pilot implementation support trial to assist CMO staff to provide preventive care to people with mental health conditions.

Adapting the Diabetes Prevention Program for Older Adults: Descriptive Study

BACKGROUND

Prediabetes affects 26.4 million people aged 65 years or older (48.8%) in the United States. Although older adults respond well to the evidence-based Diabetes Prevention Program, they are a heterogeneous group with differing physiological, biomedical, and psychosocial needs who can benefit from additional support to accommodate age-related changes in sensory and motor function.

OBJECTIVE

The purpose of this paper is to describe adaptations of the Centers for Disease Control and Prevention's Diabetes Prevention Program aimed at preventing diabetes among older adults (ages ≥65 years) and findings from a pilot of 2 virtual sessions of the adapted program that evaluated the acceptability of the content.

METHODS

The research team adapted the program by incorporating additional resources necessary for older adults. A certified lifestyle coach delivered 2 sessions of the adapted content via videoconference to 189 older adults.

RESULTS

The first session had a 34.9% (38/109) response rate to the survey, and the second had a 34% (30/88) response rate. Over three-quarters (50/59, 85%) of respondents agreed that they liked the virtual program, with 82% (45/55) agreeing that they would recommend it to a family member or a friend.

CONCLUSIONS

This data will be used to inform intervention delivery in a randomized controlled trial comparing in-person versus virtual delivery of the adapted program.

Mental health diagnosis attenuates weight loss among older adults in a digital diabetes prevention program

Objective

Diabetes Prevention Programs (DPP) are effective at reducing diabetes incidence via clinically significant weight loss. Co-morbid mental health condition(s) may reduce the effect of DPP administered in-person and telephonically but this has not been assessed for digital DPP. This report examines the moderating effect of mental health diagnosis on weight change among individuals who enrolled in digital DPP (enrollees) at 12 and 24 months.

Methods

Secondary analysis of prospective, electronic health record data from a study of digital DPP among adults (N = 3904) aged 65-75 with prediabetes (HbA1c 5.7%-6.4%) and obesity (BMI ≥30 kg/m2).

Results

Mental health diagnosis only moderated the effect of digital DPP on weight change during the first 7 months (p = 0.003) and the effect attenuated at 12 and 24 months. Results were unchanged after adjusting for psychotropic medication use. Among those without a mental health diagnosis, digital DPP enrollees lost more weight than non-enrollees: -4.17 kg (95% CI, -5.22 to -3.13) at 12 months and -1.88 kg (95% CI, -3.00 to -0.76) at 24 months, whereas among individuals with a mental health diagnosis, there was no difference in weight loss between enrollees and non-enrollees at 12 and 24 months (-1.25 kg [95% CI, -2.77 to 0.26] and 0.02 kg [95% CI, -1.69-1.73], respectively).

Conclusions

Digital DPP appears less effective for weight loss among individuals with a mental health condition, similar to prior findings for in-person and telephonic modalities. Findings suggest a need for tailoring DPP to address mental health conditions.

Informing the development of the coaching online and community health (COACH) program: a qualitative study of clubhouse members living with serious mental illness

Health and wellness interventions addressing risk factors for early mortality among individuals with serious mental illness have demonstrated success and can be further augmented with digital technology. These programs may be suitable for delivery in psychosocial rehabilitation clubhouses, especially given many services have transitioned to digital platforms during the pandemic. This qualitative study aimed to: (a) explore clubhouse members' experiences engaging with the virtual clubhouse platform, and their preferences for accessing digital wellness and health promotion content; and, (b) gauge members' interest in an online peer-driven lifestyle intervention and their suggestions for program design. This study was guided by a community-based participatory action research framework. Ten focus groups were conducted with clubhouse members. Focus groups were coded and analyzed thematically by trained clubhouse members and the research team. Thirty-three members participated in the focus groups. Participants expressed the importance of having technical support from staff; that one-on-one support and consistent communication are important to keep them engaged in health and wellness programming; and described mixed views about use of the virtual platform, but generally were open to engaging in lifestyle intervention programming virtually. Participants who joined the clubhouse during the pandemic expressed feeling overwhelmed by in-person gatherings, and were especially interested in opportunities for remote participation. This study can inform health and wellness programming for delivery on the virtual clubhouse platform for members. The taxonomy of codes, created to generate a framework with recommendations, will inform the design of a virtual health and wellness intervention.

Developing an implementation research logic model: using a multiple case study design to establish a worked exemplar

BACKGROUND

Implementation science frameworks explore, interpret, and evaluate different components of the implementation process. By using a program logic approach, implementation frameworks with different purposes can be combined to detail complex interactions. The Implementation Research Logic Model (IRLM) facilitates the development of causal pathways and mechanisms that enable implementation. Critical elements of the IRLM vary across different study designs, and its applicability to synthesizing findings across settings is also under-explored. The dual purpose of this study is to develop an IRLM from an implementation research study that used case study methodology and to demonstrate the utility of the IRLM to synthesize findings across case sites.

METHOD

The method used in the exemplar project and the alignment of the IRLM to case study methodology are described. Cases were purposely selected using replication logic and represent organizations that have embedded exercise in routine care for people with cancer or mental illness. Four data sources were selected: semi-structured interviews with purposely selected staff, organizational document review, observations, and a survey using the Program Sustainability Assessment Tool (PSAT). Framework analysis was used, and an IRLM was produced at each case site. Similar elements within the individual IRLM were identified, extracted, and re-produced to synthesize findings across sites and represent the generalized, cross-case findings.

RESULTS

The IRLM was embedded within multiple stages of the study, including data collection, analysis, and reporting transparency. Between 33-44 determinants and 36-44 implementation strategies were identified at sites that informed individual IRLMs. An example of generalized findings describing "intervention adaptability" demonstrated similarities in determinant detail and mechanisms of implementation strategies across sites. However, different strategies were applied to address similar determinants. Dependent and bi-directional relationships operated along the causal pathway that influenced implementation outcomes.

CONCLUSIONS

Case study methods help address implementation research priorities, including developing causal pathways and mechanisms. Embedding the IRLM within the case study approach provided structure and added to the transparency and replicability of the study. Identifying the similar elements across sites helped synthesize findings and give a general explanation of the implementation process. Detailing the methods provides an example for replication that can build generalizable knowledge in implementation research.

Renewed call for lifestyle interventions to address obesity among individuals with serious mental illness in the COVID-19 era and beyond

Behavioral health has the opportunity to lead the way in using lifestyle interventions to address obesity and health disparities in people with serious mental illness (SMI) in the COVID-19 era. Evidence-based interventions for weight loss in individuals with SMI exist, and the field has developed strategies for implementing these interventions in real-world mental health care settings. In addition to promoting weight loss, lifestyle interventions have the potential to address social isolation and loneliness and other patient-centered outcomes among individuals with SMI, which will be especially valuable for mitigating the growing concerns about loneliness attributed to the COVID-19 pandemic restrictions on in-person encounters. In this commentary, we discuss practice, policy, and research implications related to using evidence-based lifestyle interventions for individuals with SMI during the COVID-19 pandemic and sustaining these programs in the long-term.

A randomized trial to decrease risk for diabetes among Cambodian Americans with depression: Intervention development, baseline characteristics and process outcomes

Background:

Depression and antidepressant medications are associated with increased risk for type 2 diabetes. It is not known if diabetes can be prevented in the setting of depression. Cambodian Americans have high rates of both depression and diabetes. This paper reports intervention development, experimental design, baseline characteristics, and process outcomes of diabetes prevention interventions for Cambodian Americans with depression, “Diabetes Risk Reduction through Eat, Walk, Sleep and Medication Therapy Management” (DREAM).

Methods:

Participants were aged 35–75, Khmer speaking, at high risk for developing diabetes, and met criteria for likely depression by either a) antidepressant medication and/or b) elevated depressive symptoms at two time-points during a study eligibility period. Treatment arms were: 1) community health educator (CHE) delivered lifestyle intervention called Eat, Walk, Sleep (EWS), 2) EWS plus pharmacist/CHE-delivered medication therapy management (EWS + MTM), and, 3) social services (SS; control).

Results:

188 participants were randomized. Treatment fidelity was high (98% checklist adherence) and on a scale from 0 to 3, participants reported high EWS treatment satisfaction (M = 2.9, SD = 0.2), group cohesion (M = 2.9, SD = 0.3), and therapeutic alliance to CHEs (M = 2.9, SD = 0.2) and to pharmacists (2.9, SD = 0.3). Attendance was challenging but highly successful; in EWS, 99% attended ≥ one session and 86% completed ≥ 24 sessions, M = 27.3 (SD = 3.7) sessions. Of those randomized to EWS + MTM, 98% attended at least one MTM session and 77%) completed ≥ 4 sessions. Retention was high, 95% at 12-month and 96% at 15-month assessments.

Conclusions:

The interventions were successfully implemented. Lessons learned and suggestions for future trials are offered.

Implementing Exercise in Healthcare Settings: The Potential of Implementation Science

Exercise is an efficacious therapy for many chronic diseases. Integrating efficacious evidence-based interventions (EBIs), such as exercise, into daily healthcare practice is a slow and complex pursuit. Implementation science seeks to understand and address this phenomenon by conducting studies about the methods used to promote the routine uptake of EBIs. The purpose of this article is to explore implementation science and a common conceptual framework in the discipline, the Consolidated Framework for Implementation Research (CFIR), as it applies to exercise EBI. We conclude by offering recommendations for future research that leverage implementation science priorities to highlight the potential of this research field for advancing the implementation of exercise EBI.

Tailoring an evidence-based lifestyle intervention to meet the needs of women Veterans with prediabetes

Prediabetes affects one-third of U.S. adults. Lifestyle change interventions, such as the Diabetes Prevention Program (DPP), can significantly lower type 2 diabetes risk, but little is known about how the DPP could be best adapted for women. This mixed-methods study assessed the impact of gender-tailoring and modality choice on DPP engagement among women Veterans with prediabetes. Participants were offered women-only groups and either in-person/peer-led or online modalities. Implementation outcomes were assessed using attendance logs, recruitment calls, and semi-structured interviews about patient preferences. Between June 2016 and March 2017, 119 women Veterans enrolled in the DPP (n = 51 in-person, n = 68 online). We conducted 22 interviews between August and September 2016 (n = 10 early-implementation) and March and July 2017 (n = 12 follow-up). Most interviewees preferred women-only groups, citing increased comfort, camaraderie, and mutual understanding of gender-specific barriers to lifestyle change. More women preferred online DPP, and those using this modality participated at higher rates. Most endorsed the importance of modality choice and were satisfied with their selection; however, selection was frequently based on participants' personal circumstances and access barriers and not on a "preferred choice" of two equally accessible options. Patient engagement and program reach can be expanded by tailoring the DPP for population-specific needs.

A systematic review of recruitment strategies and behaviour change techniques in group-based diabetes prevention programmes focusing on uptake and retention

BACKGROUND

Many countries worldwide have developed diabetes prevention programmes (DPPs) that involve lifestyle modification. Research has shown that uptake and retention of DPPs are important and by exploring recruitment strategies and behaviour change techniques (BCTs) used, factors that are most effective in promoting uptake and retention can be identified.

OBJECTIVES

This review aims to identify recruitment strategies of group-based DPPs that are associated with high uptake and common BCTs associated with high retention.

METHODS

Papers were identified with a systematic literature search. Programmes that were predominantly group-based and involved lifestyle modification and in which uptake and/or retention could be determined, were included. Intervention details were extracted, recruitment strategies and BCTs identified, and response, uptake and retention rates were calculated.

RESULTS

A range of recruitment strategies were used making it difficult to discern associations with uptake rates. For BCTs, all programmes used a credible source, 81% used instruction on how to perform a behaviour and 71% used goal setting (behaviour). BCTs more commonly found in high retention programmes included problem-solving, demonstrating the behaviour, using behavioural practice and reducing negative emotions.

CONCLUSIONS

Recommendations include that DPPs incorporate BCTs like problem-solving and demonstrating the behaviour to maximise retention.

Is it possible for people with severe mental illness to sit less and move more? A systematic review of interventions to increase physical activity or reduce sedentary behaviour

Individuals with severe mental illness (SMI) (schizophrenia-spectrum, bipolar disorder and major depressive disorder) die 10-20 years prematurely due to physical disorders such as cardiovascular disease. Physical activity (PA) is effective in preventing and managing these conditions in the general population, however individuals with SMI engage in substantially less PA and more sedentary behaviour (SB) compared to healthy counterparts. Furthermore, the effectiveness of intervening to increase PA or reduce SB in SMI populations is unknown. Therefore, we systematically reviewed studies measuring changes in PA or SB following behavioural interventions in people with SMI. A systematic search of major databases was conducted from inception until 1/3/2018 for behavioural interventions reporting changes in PA or SB in people with SMI. From 3018 initial hits, 32 articles were eligible, including 16 controlled trials (CT's; Treatment n = 1025, Control n = 1162) and 16 uncontrolled trials (n = 655). Of 16 CTs, seven (47%) reported significant improvements in PA, although only one found changes with an objective measure. Of 16 uncontrolled trials, 3 (20%) found improvements in PA (one with objective measurement). No intervention study had a primary aim of changing SB, nor did any note changes in SB using an objective measure. In conclusion, there is inconsistent and low quality evidence to show that interventions can be effective in changing PA or SB in this population. Future robust randomized controlled trials, using objectively-measured PA/SB as the primary outcome, are required to determine which behavioural interventions are effective in improving the sedentary lifestyles associated with SMI.
