The National Clinical Care Commission report to Congress: background, methods, and foundational recommendations.
This AHRQ-authored paper describes the background, methods, and recommendations of the National Clinical Care Commission (NCCC) focused on factors likely to improve the delivery of high-quality care to all people with diabetes. It is the first in a series of five articles describing the recommendations. The Commission made recommendations at all levels: patient, practice, health system, and health policy. This is the first paper in a series of five articles about the NCCC recommendations. The five articles include recommendations to 1) reduce diabetes-related risks, prevent type 2 diabetes, and avert diabetes complications through changes in federal policies and programs affecting the general population; 2) prevent type 2 diabetes in at-risk individuals through targeted lifestyle and medication interventions; and 3) improve the treatment of diabetes and its complications to improve the health outcomes of people with diabetes. This first article reviews the successes and limitations of previous federal efforts to combat diabetes, describes the establishment of and charge to the NCCC, and discusses the development of a hybrid conceptual model that guided the NCCC’s novel all-of-government approach to address diabetes as a societal and medical problem. The authors then review the procedures used by the NCCC to gather information from federal agencies, stakeholders, key informants, and the public and to conduct literature reviews. Finally, they review the NCCC's three foundational recommendations: 1) improve the coordination of non-health-related and health-related federal agencies to address the social and environmental conditions that are accelerating the diabetes epidemic; 2) ensure that all Americans at risk for and with diabetes have health insurance and access to health care; and 3) ensure that all federal policies and programs promote health equity in diabetes.

Clinical trial recruitment and retention of college students with type 1 diabetes via social media: an implementation case study.
The purpose of this study was to quantify the efficiency and acceptability of Internet-based recruitment for engaging college-students with type 1 diabetes (T1D) and to describe the approach used for implementing a health-related trial entirely online using off-the-shelf Internet tools. Young people aged 17-25 years with T1D were recruited through social media platforms and other outreach channels; Facebook was the highest yield recruitment source. Demographics differed by platform. Response rate and participant characteristics were quantified and engagement metrics tracked via Google Analytics and participant survey data. The researchers conclude that recruitment of college students with T1D for a trial via social media is feasible, efficient, acceptable, and yields a sample that represents the user-base from which they were drawn.

The timing and frequency of trial inclusion in systematic reviews of type 2 diabetes drugs was associated with trial characteristics.
The purpose of this study was to determine whether certain trial characteristics are associated with faster or more frequent inclusion in systematic reviews for drug interventions in type 2 diabetes. Results showed that time to inclusion was shorter for trials with industry funding, more participants, and published in higher impact factor journals, while frequency of inclusion was greater for trials with industry funding, more participants, positive conclusions, and published in higher impact factor journals.

Marked exercise-induced T-wave heterogeneity in symptomatic diabetic patients with nonflow-limiting coronary artery stenosis.
The authors investigated whether T-wave heterogeneity (TWH) is elevated during exercise tolerance testing (ETT) in symptomatic diabetic patients with nonflow-limiting coronary artery stenosis compared to control subjects without diabetes. They found that TWH is capable of detecting latent repolarization abnormalities, which are present during ETT in diabetic patients with nonflow-limiting stenosis but not in control subjects. They concluded that the technique developed in this study permits TWH analysis from archived ECGs and thereby enables mining of extensive databases for retrospective studies and hypothesis testing.

The role of matching when adjusting for baseline differences in the outcome variable of comparative effectiveness studies.
The aim of this study was to evaluate performance of analytical strategies commonly used to adjust for baseline differences in continuous outcome variables for comparative effectiveness studies. It found that with increasing HbA1c baseline differences between groups, bias in effect estimates and suboptimal confidence interval coverage probabilities increased in all approaches. These issues were further compounded by measurement error. Matching on baseline HbA1c, substantially mitigated these issues.
