User Trust

Automated closed loop systems will greatly change type 1 diabetes management; user trust will be essential for acceptance of this new technology. This qualitative study explored trust in 32 individuals following a hybrid closed loop trial. Participants described how context-, system-, and person-level factors influenced their trust in the system. Participants attempted to override the system when they lacked trust, while trusting the system decreased self-management burdens and decreased stress. Findings highlight considerations for fostering trust in closed loop systems. Systems may be able to engage users by offering varying levels of controls to match trust preferences.

Automated insulin delivery by means of a glucose-responsive closed-loop system has often been cited as the ‘holy grail’ of type 1 diabetes management. Reflecting the technological advances in interstitial glucose measurements and wider use of continuous glucose monitoring, recent research in closed-loop glucose control has focused on the subcutaneous route for glucose measurements and insulin delivery. The primary aim of such systems is to keep blood glucose within the target range while minimising the risk of hypoglycaemia with minimal input from the user. This article examines recent developments in the field of interstitial glucose measurement, limitations of the current generation of devices and implications on the performance of closed-loop systems. Clinical results and the advantages and disadvantages of different closed-loop configurations are summarised. Potential future advances in closed-loop systems are highlighted.

Background: Gastroparesis is associated with unpredictable gastric emptying and can lead to erratic glucose profiles and negative impacts on quality-of-life. Many people with gastroparesis are unable to meet glycemic targets and there is a need for new approaches for this population. Hybrid closed-loop systems improve glucose control and quality-of-life but evidence for their use in people with diabetic gastroparesis is limited. Methods: We present a narrative review of the challenges associated with type 1 diabetes management for people with gastroparesis and present a case series of 7 people with type 1 diabetes and gastroparesis. We compare glycemic control before and during the first 12 months of hybrid closed-loop therapy. Data were analyzed using electronic patient records and glucose management platforms. We also discuss future advancements for closed-loop systems that may benefit this population. Results: Five of 7 patients had data available for time in range before and during hybrid closed-loop therapy, and all had an improvement in percentage time in target glucose range, with the overall mean time in range increasing from 26.0% ± 15.7% to 58.4% ± 8.6% during HCL use, ( P = .004). There were significant reductions in HbA1c (83 ± 9 mmol/mol to 71 ± 14 mmol/mol) and mean glucose from 13.0 ± 1.7 mmol/L (234 ± 31 mg/dL) to 10.0 ± 0.7 mmol/L (180 ± 13 mg/dL) with use of a hybrid closed-loop system. Importantly, this was achieved without an increase in time in hypoglycemia ( P = .50). Conclusion: Hybrid closed-loop systems may represent a valuable approach to improve glycemic control for people with type 1 diabetes and gastroparesis. Prospective studies are required to confirm these findings.

Supportive Role

Achieving normal or near-normal glycemic control as reflected by HbA1c levels in patients with type 1 diabetes (T1D) is important for preventing the development and progression of chronic complications. Despite delineation and dissemination of HbA1c management targets and advances in insulin pharmacology, insulin delivery systems, and glucose monitoring, the majority of children with T1D do not achieve HbA1c goals. In particular, African Americans are more likely not to reach HbA1c goals and have persistently higher HbA1c than Non-Hispanic Whites. Availability of pumps and other technology has not eliminated the disparity in HbA1c. Multiple factors play a role in the persisting racial disparity in HbA1c outcome. The carefully designed application and deployment of new technology to help the patient/family and facilitate the supportive role of the diabetes management team may be able to overcome racial disparity in glycemic outcome and improve patient quality of life.

Difficult Time

IntroductionWhereas it is widely recognized that emerging adulthood can be a difficult time in the life of an individual living with type 1 diabetes, relatively little is known about the experiences of their parents or guardians. These individuals once shouldered much of the burden for their child’s diabetes ‘self’-management, yet their contribution is often overlooked by the adult healthcare system. Here, we set out to gain an understanding of the perspectives of parents of emerging adults living with type 1 diabetes.Research design and methodsSemi-structured interviews were performed with a purposeful sample of parents of emerging adults with type 1 diabetes recruited from two urban young adult diabetes clinics and through a national diabetes charity. Thematic coding was derived using a constant comparative approach.ResultsAnalysis of interviews with 16 parents of emerging adults with type 1 diabetes identified three themes: parental experiences of the transition to adult care; negotiating parent–child roles, responsibilities and relationships; and new and evolving fears. Parents spoke in detail about the time surrounding their child’s diagnosis of type 1 diabetes to emphasize the complexity of diabetes care and the need to establish a ‘new normal’ for the family. In turn, adolescence and emerging adulthood required a renegotiation of roles and responsibilities, with many parents continuing to play a role in high-level diabetes management. Several parents of emerging adults with type 1 diabetes (particularly those of young men) vocalized worries about their child’s readiness to assume responsibility for their self-care, and some expressed frustration with the apparent dichotomy in the role expectations of parents between the pediatric and adult care settings.ConclusionsAdult healthcare providers should recognize both the ongoing involvement of parents in the ‘self’-management of emerging adults with type 1 diabetes and the unique aspects of the caregiver burden that they experience.
