Aim: This study's aim was to compare the time and accuracy of use and participants' satisfaction and preferences with pen devices for the once-weekly glucagon-like peptide 1 (GLP-1) receptor agonists dulaglutide, exenatide XR BCise, and semaglutide.

Materials and methods: In this triple crossover, open-label, simulated injection study, GLP-1 receptor agonist pen devices were compared, with time and accuracy of use and participants' satisfaction and preferences as primary outcomes. Participants had type 2 diabetes and were naive to GLP-1 receptor agonist therapy. Participants watched instructional videos for each device, demonstrated administration, and then provided feedback after each demonstration. Investigators tracked errors and omissions of demonstration steps for accuracy and time. Differences across devices were compared using univariate mixed models, adjusting for multiple comparisons.

Results: Of the 60 participants, 50% were male, a majority (65%) were Caucasian, and most (65%) had adequate health literacy. Participants rated the dulaglutide device easier to use than those of exenatide XR BCise or semaglutide (P <0.001 for each). Participants expressed greater satisfaction with the dulaglutide device compared with those of exenatide XR BCise or semaglutide (P <0.01 for each). Most participants (75%) preferred the dulaglutide device overall; however, many participants (61%) preferred the size and portability of the semaglutide device. The dulaglutide device took less time to use than the exenatide XR BCise or semaglutide devices (69 vs. 126 and 146 seconds, respectively; P <0.001 for each). Participants were less accurate when using the dulaglutide device.

Conclusion: Most participants preferred the dulaglutide device. The dulaglutide device took the least amount of time to demonstrate; however, demonstration accuracy was lower.

Objective: Diabetes knowledge is associated with health, including lower A1C levels. The Diabetes Knowledge Questionnaire (DKQ-24), developed 30 years ago for Mexican Americans with type 2 diabetes and since used with diverse samples in many countries, contains outdated items that no longer accurately assess current knowledge needed for diabetes self-management. We revised the DKQ-24 and tested psychometric properties of the DKQ-Revised (DKQ-R) with a diverse sample.

Methods: We conducted a five-phase instrumentation study as follows: 1) DKQ-24 items were revised to reflect current diabetes care standards; 2) the Delphi method was used to evaluate the DKQ-R's content validity (n = 5 experts); 3) cognitive interviews were conducted with people with type 2 diabetes (n = 5) to assess their interpretations of DKQ-R items; 4) cross-sectional administration of the DKQ-R to adults with type 2 diabetes was carried out to assess internal consistency reliability and convergent validity; and 5) an item analysis was conducted using discrimination index and point biserial analysis.

Results: After receiving the experts' feedback and conducting the cognitive interviews, 39 items were administered to 258 participants with type 2 diabetes (42.2% women; 29.1% Latino, 42.6% Asian, mean age 55.7 years). To select the final items, we considered the item discrimination index, as well as item-to-total correlations, content area, and participant feedback. The final 22-item DKQ-R uses the same yes/no/I don't know response format as the DKQ-24. The DKQ-R is strongly correlated with the DKQ-24 (r = 0.71, P <0.01) and is weakly correlated with diabetes numeracy (r = 0.23, P <0.01), indicating adequate convergent validity; a Kuder-Richardson-20 coefficient of 0.77 indicated good reliability.

Conclusion: The DKQ-R is a reliable and valid updated measure of diabetes knowledge for diverse populations with type 2 diabetes.

Objective: School nurses are integral to optimizing diabetes management for students with type 1 diabetes. The aim of this study was to describe the use of diabetes technology in schools over time and assess school nurses' comfort level performing diabetes management tasks.

Study design: From 2012 to 2019, school nurses who attended a diabetes education program completed a survey about their experience and comfort level with diabetes management.

Results: A total of 1,796 school nurses completed the survey; 56% had at least 5 years of school nursing experience. Most (86%) had at least one student with type 1 diabetes. Among school nurses with at least one student with type 1 diabetes, 73% had at least one student using insulin pump therapy, and 48% had at least one student using continuous glucose monitoring (CGM). There was no change in pump use over time, but the percentage of nurses who had a student using CGM increased significantly from 24% in 2012 to 86% in 2019 (P <0.001). School nurses' comfort level using pumps remained stable over time. Overall, 47% reported being mostly/very comfortable giving boluses using a pump, and 17% reported being mostly/very comfortable troubleshooting problems with a pump. However, there was a significant increase in school nurses reporting feeling mostly/very comfortable working with CGM devices, increasing from 9% in 2012 to 44% in 2019 (P <0.001).

Conclusion: School nurses are an important part of diabetes management for school-aged youth with type 1 diabetes. There is a need for additional diabetes education and support to build their confidence with diabetes management and technology, especially with further technological advancements in management.

Objective: The prevalence of diabetes is higher in Black than in White individuals, and Blacks seek emergency department (ED) care for diabetes more often than Whites. This randomized controlled trial compared the efficacy of a novel intervention called the Diabetes Interprofessional Team to Enhance Adherence to Medical Care (DM I-TEAM) to usual medical care (UMC) to prevent return diabetes-related ED visits and hospitalizations over 12 months in 200 Black individuals with diabetes after an ED visit. The trial also identified baseline variables associated with return ED visits and hospitalizations.

Methods: The DM I-TEAM provided diabetes education and behavioral activation services delivered by race-concordant research assistants, telehealth visits with a diabetes care and education specialist and primary care physicians, and clinical pharmacist recommendations.

Results: Participants had a mean age of 64.9 years, and 73.0% were women. There was no treatment group difference in return diabetes-related ED visits or hospitalizations over 12 months (DM I-TEAM n = 39 [45.3%] vs. UMC n = 37 [38.5%], χ² = 0.864, P = 0.353). Baseline variables that were associated with return diabetes-related ED visits or hospitalizations were longer duration of diabetes, higher number of chronic health conditions, higher number of previous ED visits or hospitalizations, greater anticholinergic medication burden, lower satisfaction with primary care physicians, and lower trust in physicians (all P ≤0.05).

Conclusion: Among Black individuals with diabetes, the DM I-TEAM interprofessional intervention was no better than UMC at preventing return diabetes-related ED visits or hospitalizations. High medical morbidity, greater anticholinergic medication burden, low satisfaction with primary care physicians, and physician mistrust were associated with diabetes-related ED visits or hospitalizations independent of treatment. Before clinical interventions such as the DM I-TEAM can be effective, reducing system-level barriers to health, improving physician-patient relationships and medication prescribing, and building community health care capacity will be necessary.

Glucose monitoring is essential for the management of type 1 diabetes and has evolved from urine glucose monitoring in the early 1900s to home blood glucose monitoring in the 1980s to continuous glucose monitoring (CGM) today. Youth with type 1 diabetes struggle to meet A1C goals; however, CGM is associated with improved A1C in these youth and is recommended as a standard of care by diabetes professional organizations. Despite their utility, expanding uptake of CGM systems has been challenging, especially in minoritized communities. The 4T (Teamwork, Targets, Technology, and Tight Control) program was developed using a team-based approach to set consistent glycemic targets and equitably initiate CGM and remote patient monitoring in all youth with new-onset type 1 diabetes. In the pilot 4T study, youth in the 4T cohort had a 0.5% improvement in A1C 12 months after diabetes diagnosis compared with those in the historical cohort. The 4T program can serve as a roadmap for other multidisciplinary pediatric type 1 diabetes clinics to increase CGM adoption and improve glycemic outcomes.

The ambulatory glucose profile is a valuable tool in managing type 1 diabetes during pregnancy. Time in range (TIR) in the third trimester is one of the most significant parameters contributing to good pregnancy outcomes. This study aimed to evaluate the effect of intermittently scanned continuous glucose monitoring (isCGM) empowered by education on glucose dynamics and to predict third trimester TIR. Data were retrospectively analyzed from 38 pregnant patients with type 1 diabetes (mean age 30.4 ± 6.4 years, BMI 23.7 ± 3.7 kg/m², disease duration 15.4 ± 9.5 years, preconception A1C 6.9 ± 1%) who used a first-generation FreeStyle Libre isCGM system for at least 3 months before conception and had sensor data captured >70% of the time the system was used. Patients received personalized education on diabetes and on minimizing hypoglycemia and hyperglycemia using CGM trend arrows and frequent sensor scanning. This intervention improved glycemic parameters of glucose regulation (TIR, glucose management indicator, and mean glucose), hyperglycemia (time above range), glucose variability (SD and coefficient of variation [%CV]), and scanning frequency, but did not improve parameters of hypoglycemia (time below range and a number of low glucose events). Logistic regression analysis showed that the first trimester %CV and scanning frequency contributed to the third trimester TIR (P <0.01, adjusted R² 0.40). This study suggests that the use of isCGM empowered by personalized education improves glycemic control in pregnant women with type 1 diabetes. Scanning frequency and %CV in the first trimester predicts TIR in the third trimester, which could help clinicians intervene early to improve outcomes.

Background: Therapeutic inertia leading to delays in insulin initiation or intensification is a major contributor to lack of optimal diabetes care. This report reviews the literature summarizing data on therapeutic inertia and delays in insulin intensification in the management of type 2 diabetes.

Methods: A literature search was conducted of the Allied & Complementary Medicine, BIOSIS Previews, Embase, EMCare, International Pharmaceutical Abstracts, MEDLINE, and ToxFile databases for clinical studies, observational research, and meta-analyses from 2012 to 2022 using search terms for type 2 diabetes and delay in initiating/intensifying insulin. Twenty-two studies met inclusion criteria.

Results: Time until insulin initiation among patients on two to three antihyperglycemic agents was at least 5 years, and mean A1C ranged from 8.7 to 9.8%. Early insulin intensification was linked with reduced A1C by 1.4%, reduction of severe hypoglycemic events from 4 to <1 per 100 person-years, and diminution in risk of heart failure (HF) by 18%, myocardial infarction (MI) by 23%, and stroke by 28%. In contrast, delayed insulin intensification was associated with increased risk of HF (64%), MI (67%), and stroke (51%) and a higher incidence of diabetic retinopathy. In the views of both patients and providers, hypoglycemia was identified as a primary driver of therapeutic inertia; 75.5% of physicians reported that they would treat more aggressively if not for concerns about hypoglycemia.

Conclusion: Long delays before insulin initiation and intensification in clinically eligible patients are largely driven by concerns over hypoglycemia. New diabetes technology that provides continuous glucose monitoring may reduce occurrences of hypoglycemia and help overcome therapeutic inertia associated with insulin initiation and intensification.

Background: The transition to adulthood is a challenging period for individuals with type 1 diabetes, especially those attending post-secondary education (PSE) at a university or college. In addition to balancing academic responsibilities and adapting to a novel environment, young adults (YAs) with type 1 diabetes must more independently manage the daily demands of diabetes care.

Objective: The aim of this study was to collect qualitative data from multiple stakeholders addressing the transition of students with type 1 diabetes into a PSE setting.

Methods: A total of 15 participants were interviewed, including three health care provider diabetes educators, four parents of YAs with type 1 diabetes, and eight YAs with type 1 diabetes. Reflexive thematic analysis of the qualitative interviews revealed four major themes and 11 subthemes.

Results: The four major themes revealed included 1) inappropriateness of services available to support students with type 1 diabetes in PSE settings, 2) individuals with type 1 diabetes having to compensate for inadequate systems, 3) variability of social support effectiveness, and 4) the need for a more holistic approach to improve diabetes education and social support systemically.

Conclusion: This study identified some key systemic barriers experienced by PSE students with type 1 diabetes. Future research needs to extend the sample populations to understand a wider range of PSE student experiences. The findings from this study provide initial recommendations to develop new PSE readiness interventions for YAs with type 1 diabetes.
