ABSTRACT

INTRODUCTION: Online Diabetes Prevention Programs (DPPs) can be scaled up and delivered broadly. However, little is known about real-world effectiveness and how outcomes compare with in-person DPP. This study examined online DPP weight loss and participation outcomes and secondarily compared outcomes among participating individuals with parallel in-person interventions. STUDY DESIGN: A large non-randomized trial supplemented by a comparative analysis of participating individuals from a concurrent trial of two parallel in-person programs: in-person DPP and the Veterans Administration's standard of care weight loss program (MOVE!). SETTING/PARTICIPANTS: Obese/overweight Veterans with prediabetes enrolled in online DPP (n = 268) between 2013 and 2014. Similar eligibility criteria were used to enroll in-person participants between 2012 and 2014 (n = 273 in-person DPP, n = 114 MOVE!) within a separate trial. INTERVENTION: Online DPP included a virtual group format, live e-coach, weekly modules delivered asynchronously, and wireless home scales. In-person programs included eight to 22 group-based, face-to-face sessions. MAIN OUTCOMES MEASURES: Weight change at 6 and 12 months using wirelessly uploaded home scale data or electronic medical record weights from clinical in-person visits. Outcomes were analyzed between 2015 and 2017. RESULTS: From 1,182 invitations, 268 (23%) participants enrolled in online DPP. Among these, 158 (56%) completed eight or more modules; mean weight change was -4.7kg at 6 months and -4.0kg at 12 months. In a supplemental analysis of participants completing one or more sessions/modules, online DPP participants were most likely to complete eight or more sessions/modules (87% online DPP vs 59% in-person DPP vs 55% MOVE!, p < 0.001). Online and in-person DPP participants lost significantly more weight than MOVE! participants at 6 and 12 months; there was no significant difference in weight change between online and in-person DPP. CONCLUSIONS: An intensive, multifaceted online DPP intervention had higher participation but similar weight loss compared to in-person DPP. An intensive, multifaceted online DPP intervention may be as effective as in-person DPP and help expand reach to those at risk.

ABSTRACT

Teaching bioinformatics is a longstanding challenge for educators who need to demonstrate to students how skills developed in the classroom may be applied to real world research. This study employed an action research methodology which utilised student-staff partnership and peer-learning. It was centred on the experiences of peer-facilitators, students who had previously taken a postgraduate bioinformatics module, and had applied knowledge and skills gained from it to their own research. It aimed to demonstrate to peer-receivers, current students, how bioinformatics could be used in their own research while developing peer-facilitators' teaching and mentoring skills. This student-centred approach was well received by the peer-receivers, who claimed to have gained improved understanding of bioinformatics and its relevance to research. Equally, peer-facilitators also developed a better understanding of the subject and appreciated that the activity was a rare and invaluable opportunity to develop their teaching and mentoring skills, enhancing their employability.

ABSTRACT

INTRODUCTION: This clinical demonstration trial compared the effectiveness of the Veterans Affairs Diabetes Prevention Program (VA-DPP) with an evidence-based usual care weight management program (MOVE!®) in the Veterans Health Administration health system. DESIGN: Prospective, pragmatic, non-randomized comparative effectiveness study of two behavioral weight management interventions. SETTING/PARTICIPANTS: Obese/overweight Veterans with prediabetes were recruited from three geographically diverse VA sites between 2012 and 2014. INTERVENTION: VA-DPP included 22 group-based intensive lifestyle change sessions. MAIN OUTCOME MEASURES: Weight change at 6 and 12 months, hemoglobin A1c (HbA1c) at 12 months, and VA health expenditure changes at 15 months were assessed using VA electronic health record and claims data. Between- and within-group comparisons for weight and HbA1c were done using linear mixed-effects models controlling for age, gender, race/ethnicity, baseline outcome values, and site. Analyses were conducted in 2015-2016. RESULTS: A total of 387 participants enrolled (273 VA-DPP, 114 MOVE!). More VA-DPP participants completed at least one (73.3% VA-DPP vs 57.5% MOVE! p=0.002); four (57.5% VA-DPP vs 42.5% MOVE!, p=0.007); and eight or more sessions (42.5% VA-DPP vs 31% MOVE!, p=0.035). Weight loss from baseline was significant at both 6 (p<0.001) and 12 months (p<0.001) for VA-DPP participants, but only significant at 6 months for MOVE! participants (p=0.004). Between groups, there were significant differences in 6-month weight loss (-4.1 kg VA-DPP vs -1.9 kg MOVE!, p<0.001), but not 12-month weight loss (-3.4 kg VA-DPP vs -2.0 kg MOVE!, p=0.16). There were no significant differences in HbA1c change or outpatient, inpatient, and total VA expenditures. CONCLUSIONS: VA-DPP participants had higher participation rates and weight loss at 6 months, but similar weight, HbA1c, and health expenditures at 12 months compared to MOVE! PARTICIPANTS: Features of VA-DPP may help enhance the capability of MOVE! to reach a larger proportion of the served population and promote individual-level weight maintenance.

ABSTRACT

Our aim was to determine whether rheumatoid arthritis (RA) low-density granulocytes (LDGs) are functionally different from RA neutrophils. LDGs from 32 RA patients were characterized using flow cytometry and quantitative PCR (qPCR). RNA sequencing (RNA-Seq) was carried out on paired RA LDGs and neutrophils (n = 4) and validated using qPCR. Functional assays included chemotaxis, phagocytosis, reactive oxygen species (ROS) production, cell-cycle analysis, apoptosis, neutrophil extracellular trap (NET)osis, and measurement of cytokine production (n ≥ 5 paired RA LDGs/neutrophils). RA LDGs had a substantially altered transcriptome, expressing >5000 genes at significantly different levels compared with RA neutrophils, including elevated levels of transcripts for granule proteins [including elastase and myeloperoxidase (MPO)] and cell-cycle genes [including cyclin-dependent kinase (CDK)2, CDK4, and CDK6]. Approximately 1% of RA LDGs stained positive for the G2/S phase of the cell cycle. RA LDGs had a significantly lower constitutive rate of apoptosis compared with RA neutrophils and did not respond to TNF-α in culture. Expression of transcripts for cytokines and cytokine receptors was lower in RA LDGs. NET formation was lower in LDGs in response to PMA compared with RA neutrophils. Chemotaxis and phagocytosis was lower in RA LDGs compared with neutrophils. RA LDGs produced significantly lower amounts of ROS in response to fMLP following priming with TNF-α. Expression of TNFR1 and -2 mRNA and protein was significantly lower in LDGs. We conclude that RA LDGS are functionally different from RA neutrophils, representing an immature neutrophil population within peripheral blood. Their enhanced survival properties and decreased TNF signaling are likely to have important consequences for disease pathology and response to therapy.

ABSTRACT

Type 2 diabetes prevention is an important national goal for the Veteran Health Administration (VHA): one in four Veterans has diabetes. We implemented a prediabetes identification algorithm to estimate prediabetes prevalence among overweight and obese Veterans at Department of Veterans Affairs (VA) medical centers (VAMCs) in preparation for the launch of a pragmatic study of Diabetes Prevention Program (DPP) delivery to Veterans with prediabetes. This project was embedded within the VA DPP Clinical Demonstration Project conducted in 2012 to 2015. Veterans who attended orientation sessions for an established VHA weight-loss program (MOVE!) were recruited from VAMCs with geographically and racially diverse populations using existing referral processes. Each site implemented and adapted the prediabetes identification algorithm to best fit their local clinical context. Sites relied on an existing referral process in which a prediabetes identification algorithm was implemented in parallel with existing clinical flow; this approach limited the number of overweight and obese Veterans who were assessed and screened. We evaluated 1,830 patients through chart reviews, interviews, and/or laboratory tests. In this cohort, our estimated prevalence rates for normal glycemic status, prediabetes, and diabetes were 29% (n = 530), 28% (n = 504), and 43% (n = 796), respectively. Implementation of targeted prediabetes identification programs requires careful consideration of how prediabetes assessment and screening will occur.

ABSTRACT

BACKGROUND: The Diabetes Prevention Program (DPP) study showed that lifestyle intervention resulted in a 58% reduction in incidence of type 2 diabetes among individuals with prediabetes. Additional large randomized controlled trials have confirmed these results, and long-term follow-up has shown sustained benefit 10-20 years after the interventions ended. Diabetes is a common and costly disease, especially among Veterans, and despite strong evidence supporting the feasibility of type 2 diabetes prevention, the DPP has not been widely implemented. The first aim of this study will evaluate implementation of the Veterans Affairs (VA) DPP in three VA medical centers. The second aim will assess weight and hemoglobin A1c (A1c) outcomes, and the third aim will determine the cost-effectiveness and budget impact of implementation of the VA DPP from a health system perspective. METHODS/DESIGN: This partnered multi-site non-randomized systematic assignment study will use a highly pragmatic hybrid effectiveness-implementation type III mixed methods study design. The implementation and administration of the VA DPP will be funded by clinical operations while the evaluation of the VA DPP will be funded by research grants. Seven hundred twenty eligible Veterans will be systematically assigned to the VA DPP clinical demonstration or the usual care VA MOVE!® weight management program. A multi-phase formative evaluation of the VA DPP implementation will be conducted. A theoretical program change model will be used to guide the implementation process and assess applicability and feasibility of the DPP for VA. The Consolidated Framework for Implementation Research (CFIR) will be used to guide qualitative data collection, analysis, and interpretation of barriers and facilitators to implementation. The RE-AIM framework will be used to assess Reach, Effectiveness, Adoption, Implementation, and Maintenance of the VA DPP. Twelve-month weight and A1c change will be evaluated for the VA DPP compared to the VA MOVE! PROGRAM: Mediation analyses will be conducted to identify whether program design differences impact outcomes. DISCUSSION: Findings from this pragmatic evaluation will be highly applicable to practitioners who are tasked with implementing the DPP in clinical settings. In addition, findings will determine the effectiveness and cost-effectiveness of the VA DPP in the Veteran population.

ABSTRACT

BACKGROUND: Diabetes prevention is a national goal and particularly important in the Veterans Health Administration (VHA) where 1 in 4 veterans has diabetes. There is growing evidence to support the use of Web-based diabetes prevention program (DPP) interventions, shown to be as effective and often more feasible than in-person interventions. OBJECTIVE: Our primary objective was to qualitatively explore women veterans' early experiences with a Web-based DPP intervention. Our secondary objective was to estimate weight loss, participation, and engagement to provide context for our qualitative findings. METHODS: We conducted and analyzed semistructured interviews and collected data on weight change, participation, and engagement. A total of 17 women veterans with prediabetes from a Midwest VA Women's Health Clinic were eligible to participate; 15 completed interviews. RESULTS: Participants perceived the DPP program as an appealing way of initiating lifestyle changes and made them feel accountable in achieving their daily goals. The online program was convenient because it could be accessed at any time, and many found that it integrated well into daily life. However, some did not like the logging aspect and some found it to be too impersonal. Participants logged in a mean 76 times, posted a mean 46 group messages, and sent a mean 20.5 private messages to the health coach over 16 weeks. Participants lost 5.24% of baseline weight, and 82% (14/17) of participants completed at least 9 of 16 core modules. CONCLUSIONS: Women veterans' early experiences with a Web-based DPP intervention were generally positive. Accountability and convenience were key enabling factors for participation and engagement. A Web-based DPP intervention appears to be a promising means of translating the DPP for women veterans with prediabetes.

ABSTRACT

BACKGROUND: Resource barriers complicate diabetes care management. Support from peers may help patients manage their diabetes. OBJECTIVE: To compare a reciprocal peer-support (RPS) program with nurse care management (NCM). DESIGN: Randomized, controlled trial. (ClinicalTrials.gov registration number: NCT00320112) SETTING: 2 U.S. Department of Veterans Affairs health care facilities. PATIENTS: 244 men with hemoglobin A(1c) (HbA(1c)) levels greater than 7.5% during the previous 6 months. MEASUREMENTS: The primary outcome was 6-month change in HbA(1c) level. Secondary outcomes were changes in insulin therapy; blood pressure; and patient reports of medication adherence, diabetes-related support, and emotional distress. INTERVENTION: Patients in the RPS group attended an initial group session to set diabetes-related behavioral goals, receive peer communication skills training, and be paired with another age-matched peer patient. Peers were encouraged to talk weekly using a telephone platform that recorded call occurrence and provided reminders to promote peer contact. These patients could also participate in optional group sessions at 1, 3, and 6 months. Patients in the NCM group attended a 1.5-hour educational session and were assigned to a nurse care manager. RESULTS: Of the 244 patients enrolled, 216 (89%) completed the HbA(1c) assessments and 231 (95%) completed the survey assessments at 6 months. Mean HbA(1c) level decreased from 8.02% to 7.73% (change, -0.29%) in the RPS group and increased from 7.93% to 8.22% (change, 0.29%) in the NCM group. The difference in HbA(1c) change between groups was 0.58% (P = 0.004). Among patients with a baseline HbA(1c) level greater than 8.0%, those in the RPS group had a mean decrease of 0.88%, compared with a 0.07% decrease among those in the NCM group (between-group difference, 0.81%; P < 0.001). Eight patients in the RPS group started insulin therapy, compared with 1 patient in the NCM group (P = 0.020). Groups did not differ in blood pressure, self-reported medication adherence, or diabetes-specific distress, but the RPS group reported improvement in diabetes social support. LIMITATION: The study included only male veterans and lasted only 6 months. CONCLUSION: Reciprocal peer support holds promise as a method for diabetes care management.

ABSTRACT

BACKGROUND: Despite being a critical part of improving healthcare quality, little is known about how best to move important research findings into clinical practice. To address this issue, the Department of Veterans Affairs (VA) developed the Quality Enhancement Research Initiative (QUERI), which provides a framework, a supportive structure, and resources to promote the more rapid implementation of evidence into practice. METHODS: This paper uses a practical example to demonstrate the use of the six-step QUERI process, which was developed as part of QUERI and provides a systematic approach for moving along the research to practice pipeline. Specifically, we describe a series of projects using the six-step framework to illustrate how this process guided work by the Diabetes Mellitus QUERI (DM-QUERI) Center to assess and improve eye care for veterans with diabetes. RESULTS: Within a relatively short time, DM-QUERI identified a high-priority issue, developed evidence to support a change in the diabetes eye screening performance measure, and identified a gap in quality of care. A prototype scheduling system to address gaps in screening and follow-up also was tested as part of an implementation project. We did not succeed in developing a fully functional pro-active scheduling system. This work did, however, provide important information to help us further understand patients' risk status, gaps in follow-up at participating eye clinics, specific considerations for additional implementation work in the area of proactive scheduling, and contributed to a change in the prevailing diabetes eye care performance measure. CONCLUSION: Work by DM-QUERI to promote changes in the delivery of eye care services for veterans with diabetes demonstrates the value of the QUERI process in facilitating the more rapid implementation of evidence into practice. However, our experience with using the QUERI process also highlights certain challenges, including those related to the hybrid nature of the research-operations partnership as a mechanism for promoting rapid, system-wide implementation of important research findings. In addition, this paper suggests a number of important considerations for future implementation work, both in the area of pro-active scheduling interventions, as well as for implementation science in general.

ABSTRACT

To examine circumstances surrounding suboptimally timed retinal photocoagulation, we reviewed the medical records of 238 patients who had received photocoagulation for diabetic retinopathy at one of three large referral centers. Forty-three percent (95% confidence interval, 36% to 49%) of cases were rated as probably or definitely suboptimally timed (i.e., patient could have benefited from earlier photocoagulation). About one third of cases were due to patients going many years without screening (> 3 years), and two thirds were associated with surveillance problems (failures to achieve close follow-up for known retinopathy). We found that suboptimal timing of photocoagulation was common but was not due to patients going between 13 and 36 months between screening visits, suggesting that current performance measures, which focus on annual retinal examinations, may be requiring wasteful care while not addressing a major quality problem.

ABSTRACT

OBJECTIVE: Many adults experience chronic pain, yet little is known about the consequences of such pain among individuals with diabetes. The purpose of this study was to examine whether and how chronic pain affects diabetes self-management. RESEARCH DESIGN AND METHODS: This is a cross-sectional study of 993 patients with diabetes receiving care through the Department of Veterans Affairs (VA). Data on chronic pain, defined as pain present most of the time for 6 months or more during the past year, and diabetes self-management were collected through a written survey. Multivariable regression techniques were used to examine the association between the presence and severity of chronic pain and difficulty with diabetes self-management, adjusting for sociodemographic and other health characteristics including depression. RESULTS: Approximately 60% of respondents reported chronic pain. Patients with chronic pain had poorer diabetes self-management overall (P = 0.002) and more difficulty following a recommended exercise plan (adjusted odds ratio [OR] 3.0 [95% CI 2.1-4.1]) and eating plan (1.6 [1.2-2.1]). Individuals with severe or very severe pain, compared with mild or moderate, reported significantly poorer diabetes self-management (P = 0.003), including greater difficulty with taking diabetes medications (2.0 [1.2-3.4]) and exercise (2.5 [1.3-5.0]). CONCLUSIONS: Chronic pain was prevalent in this cohort of patients with diabetes. Even after controlling for general health status and depressive symptoms, chronic pain was a major limiting factor in the performance of self-care behaviors that are important for minimizing diabetes-related complications. Competing demands, such as chronic pain, should be considered when working with patients to develop effective diabetes self-care regimens.
