The Shared Health Appointments and Reciprocal Enhanced Support (SHARES) study: study protocol for a randomized trial

Evaluating the Effectiveness of Diabetes Shared Medical Appointments (SMAs) as Implemented in Five Veterans Affairs Health Systems: a Multi-site Cluster Randomized Pragmatic Trial

OBJECTIVE

To examine whether diabetes shared medical appointments (SMAs) implemented as part of usual clinical practice in diverse health systems are more effective than usual care in improving and sustaining A1c improvements.

RESEARCH DESIGN AND METHODS

A multi-site cluster randomized pragmatic trial examining implementation in clinical practice of diabetes SMAs in five Veterans Affairs (VA) health systems was conducted from 2016 to 2020 among 1537 adults with type 2 diabetes and elevated A1cs. Eligible patients were randomly assigned to either: (1) invitation to participate in a series of SMAs totaling 8-9 h; or (2) continuation of usual care. Relative change in A1c (primary outcome) and in systolic blood pressure, insulin starts, statin starts, and anti-hypertensive medication classes (secondary outcomes) were measured as part of usual clinical care at baseline, at 6 months and at 12 months (~7 months after conclusion of the final SMA in four of five sites). We examined outcomes in three samples of SMA participants: all those scheduled for a SMA, those attending at least one SMA, and those attending at least half of SMAs.

RESULTS

Baseline mean A1c was 9.0%. Participants scheduled for an SMA achieved A1c reductions 0.35% points greater than the control group between baseline and 6-months follow up (p = .001). Those who attended at least one SMA achieved reductions 0.42 % points greater (p < .001), and those who attended at least half of scheduled SMAs achieved reductions 0.53 % points greater (p < .001) than the control group. At 12-month follow-up, the three SMA analysis samples achieved reductions from baseline ranging from 0.16 % points (p = 0.12) to 0.29 % points (p = .06) greater than the control group.

CONCLUSIONS

Diabetes SMAs as implemented in real-life diverse clinical practices improve glycemic control more than usual care immediately after the SMAs, but relative gains are not maintained. Our findings suggest the need for further study of whether a longer term SMA model or other follow-up strategies would sustain relative clinical improvements associated with this intervention.

Enhancing Diabetes Self-Management Education and Psychological Services for Veterans With Comorbid Chronic Health and Mental Health Conditions

Background

Veterans experience a higher prevalence of type 2 diabetes mellitus (T2DM) compared with the rate of their civilian counterparts. Veterans may experience vulnerability to chronic stress, in particular comorbid mental health conditions, and may not benefit from traditional diabetes education.

Methods

This study evaluated clinical and psychological measures among veterans engaged in health psychology services. Individualized motivational interviewing and cognitive behavioral interventions were provided to address T2DM distress and promote veterans' diabetes self-management. Pre-/postobjective and self-report measures were evaluated for clinical relevancy and statistically significant changes.

Results

The sample consisted of 13 older adults: mean age 62.8 years; 12 were male and 9 were prescribed insulin. More than half had comorbid hypertension, hyperlipidemia, and/or a diagnosis of chronic pain. Eleven participants were diagnosed with a mental health disorder. Baseline measures indicated mild depressive symptoms, mild anxiety symptoms, and moderate levels of T2DM distress. Postintervention reductions were shown for T2DM distress; emotional burden, and regimen-related distress, depressive symptoms, and enhanced diabetes empowerment.

Conclusions

Veterans with comorbid conditions may benefit from individualized psychology services that offer cognitive behavioral strategies for self-management of T2DM-related distress, integrated with traditional primary care and diabetes education.

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.

Formative evaluation and adaptation of pre-and early implementation of diabetes shared medical appointments to maximize sustainability and adoption

Background

Understanding the many factors that influence implementation of new programs, in addition to their success or failure, is extraordinarily complex. This qualitative study examines the implementation and adaptation process of two linked clinical programs within Primary Care, diabetes shared medical appointments (SMAs) and a reciprocal Peer-to-Peer (P2P) support program for patients with poorly controlled diabetes, through the lens of the Consolidated Framework for Implementation Research (CFIR). We illustrate the role and importance of pre-implementation interviews for guiding ongoing adaptations to improve implementation of a clinical program, achieve optimal change, and avoid type III errors.

Methods

We conducted 28 semi-structured phone interviews between September of 2013 and May of 2016, four to seven interviewees at each site. The interviewees were physician champions, chiefs of primary care, pharmacists, dieticians, nurses, health psychologists, peer facilitators, and research coordinators. Modifiable barriers and facilitators to implementation were identified and adaptations documented. Data analysis started with immersion in the data to obtain a sense of the whole and then by cataloging principal themes per CFIR constructs. An iterative consensus-building process was used to code. CFIR constructs were then ranked and compared by the researchers.

Results

We identified a subset of CFIR constructs that are most likely to play a role in the effectiveness of the diabetes SMAs and P2P program based on our work with the participating sites to date. Through the identification of barriers and facilitators, a subset of CFIR constructs arose, including evidence strength and quality, relative advantage, adaptability, complexity, patient needs and resources, compatibility, leadership engagement, available resources, knowledge and beliefs, and champions.

Conclusions

We described our method for identification of contextual factors that influenced implementation of complex diabetes clinical programs - SMAs and P2P. The qualitative phone interviews aided implementation through the identification of modifiable barriers or conversely, actionable findings. Implementation projects, and certainly clinical programs, do not have unlimited resources and these interviews allowed us to determine which facets to target and act on for each site. As the study progresses, these findings will be compared and correlated to outcome measures. This comprehensive adaptation data collection will also facilitate and enhance understanding of the future success or lack of success of implementation and inform potential for translation and public health impact. The approach of using the CFIR to guide us to actionable findings and help us better understand barriers and facilitators has broad applicability and can be used by other projects to guide, adapt, and improve implementation of research into practice.
