Service use and glycaemic control of young people with type 1 diabetes transitioning from paediatric to adult care: a 5-year study.

BACKGROUND: Regular contact with specialist care has been linked to better diabetes outcomes for young people with type 1 diabetes (YPwT1D), but evidence is limited to population-based service usage and outcomes. AIMS: This observational 5-year study sought to capture YPwT1D living in the study catchment area (covering metropolitan, regional and rural Australia) as they transitioned to adult-based diabetes healthcare services and to describe their glycaemic control and complication rates, service usage and associated factors. METHODS: Records between 2010 and 2014 in a public healthcare specialist diabetes database were extracted, care processes and outcomes were described, and associations were sought between episodes of care (EOC) and potentially predictive variables. RESULTS: Annual cohort numbers increased yearly, but without significant differences in demographic characteristics. Each year around 40% had no reported planned specialist care, and the average number of planned EOC decreased significantly year on year. Overall, mean HbA1c levels also reduced significantly, but with higher values recorded for those living in non-metropolitan than metropolitan areas (achieving significance in 3 out of 5 years). Diabetes complication assessments were only reported in 37-46%, indicating one in five with retinopathy and hypertension affecting one in three to five young people. CONCLUSIONS: Findings highlight the importance of investment to address the specific needs of adolescents and young adults and demonstrate the need for better support during these vulnerable early years, particularly for non-metropolitan residents. This will entail changes to funding mechanisms, the health workforce and infrastructure, and new models of care to provide equity of access and quality of specialist care.

Travel health practices, behaviours and experiences of people living with type 1 diabetes.

INTRODUCTION: There is limited data regarding the international travel history and preparation, as well as glycaemic control practices, risk behaviours, and experiences of people with type 1 diabetes during travel. Our review aimed to address the research question: 'What are the health practices, behaviours, and experiences of people with type 1 diabetes when travelling?' METHODS: We conducted a mixed-methods narrative review using adapted review methods from the Centre for Reviews and Dissemination and standards developed by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. MEDLINE, Scopus, PubMed and CINAHL, and the reference lists of all eligible studies were searched. RESULTS: Nine records comprising of eleven studies were included, with data heralding from various countries, published between 1990 and 2022. We identified three main themes: travel preparation (type of travel, planning, and advice seeking); issues related to air travel (airports and airport security, hypoglycaemia and hyperglycaemia, and insulin); and general travel-related issues (illness and medical treatment, type 1 diabetes management, and major concerns and barriers). CONCLUSIONS: Our findings highlighted the lack of quality data regarding type 1 diabetes and travel within the extant literature, as well the pressing need for empirical studies to be undertaken and consensus guidelines developed to improve the travel experiences of people with type 1 diabetes. Unless change is made, people with type 1 diabetes will continue to experience preventable risk and harm while travelling.

Demographic, Clinical, Management, and Outcome Characteristics of 8,004 Young Children With Type 1 Diabetes.

OBJECTIVE: To compare demographic, clinical, and therapeutic characteristics of children with type 1 diabetes age <6 years across three international registries: Diabetes Prospective Follow-Up Registry (DPV; Europe), T1D Exchange Quality Improvement Network (T1DX-QI; U.S.), and Australasian Diabetes Data Network (ADDN; Australasia). RESEARCH DESIGN AND METHODS: An analysis was conducted comparing 2019-2021 prospective registry data from 8,004 children. RESULTS: Mean ± SD ages at diabetes diagnosis were 3.2 ± 1.4 (DPV and ADDN) and 3.7 ± 1.8 years (T1DX-QI). Mean ± SD diabetes durations were 1.4 ± 1.3 (DPV), 1.4 ± 1.6 (T1DX-QI), and 1.5 ± 1.3 years (ADDN). BMI z scores were in the overweight range in 36.2% (DPV), 41.8% (T1DX-QI), and 50.0% (ADDN) of participants. Mean ± SD HbA1c varied among registries: DPV 7.3 ± 0.9% (56 ± 10 mmol/mol), T1DX-QI 8.0 ± 1.4% (64 ± 16 mmol/mol), and ADDN 7.7 ± 1.2% (61 ± 13 mmol/mol). Overall, 37.5% of children achieved the target HbA1c of <7.0% (53 mmol/mol): 43.6% in DPV, 25.5% in T1DX-QI, and 27.5% in ADDN. Use of diabetes technologies such as insulin pump (DPV 86.6%, T1DX 46.6%, and ADDN 39.2%) and continuous glucose monitoring (CGM; DPV 85.1%, T1DX-QI 57.6%, and ADDN 70.5%) varied among registries. Use of hybrid closed-loop (HCL) systems was uncommon (from 0.5% [ADDN] to 6.9% [DPV]). CONCLUSIONS: Across three major registries, more than half of children age <6 years did not achieve the target HbA1c of <7.0% (53 mmol/mol). CGM was used by most participants, whereas insulin pump use varied across registries, and HCL system use was rare. The differences seen in glycemia and use of diabetes technologies among registries require further investigation to determine potential contributing factors and areas to target to improve the care of this vulnerable group.

Primary Benign Neoplasms of the Spine.

Benign tumours comprise the majority of primary vertebral tumours, and these are often found incidentally on imaging. Nonetheless, accurate diagnosis of these benign lesions is crucial, in order to avoid misdiagnosis as more ominous malignant lesions or infection. Furthermore, some of these tumours, despite their benign nature, can have localised effects on the spine including neural compromise, or can be locally aggressive, thus necessitating active management. Haemangiomas and osteomas (enostosis) are the commonest benign tumours encountered. Others include osteoid osteoma, osteoblastoma, fibrous dysplasia, osteochondroma, chondroblastoma, haemangioma, simple bone cysts, aneurysmal bone cysts, giant cell tumours, eosinophilic granuloma and notochordal rests. The majority of lesions are asymptomatic; however, locally aggressive lesions (such as aneurysmal bone cysts or giant cell tumours) can present with nonspecific symptoms, such as back pain, neurological deficits and spinal instability, which may be indistinguishable from more commonly encountered mechanical back pain or malignant lesions including metastases. Hence, imaging, including radiography, computed tomography (CT) and magnetic resonance imaging (MRI), plays a critical role in diagnosis. Generally, most incidental or asymptomatic regions are conservatively managed or may not require any follow-up, while symptomatic or locally aggressive lesions warrant active interventions, which include surgical resection or percutaneous treatment techniques. Due to advances in interventional radiology techniques in recent years, percutaneous minimally invasive techniques such as radiofrequency ablation, sclerotherapy and cryoablation have played an increasing role in the management of these tumours with favourable outcomes. The different types of primary benign vertebral tumours will be discussed in this article with an emphasis on pertinent imaging features.

Measurement Analysis of Ice Ball Size during CT-Guided Cryoablation Procedures for Better Prediction of Final Ice Ball Size and Avoidance of Complications.

Introduction Cryoablation is the destruction of living tissue by the application of extreme freezing temperature. There has been an increase in the use of cryoablation in the management of musculoskeletal lesions, in particular fibromatosis. Aim This study aimed to measure the average and relative increase in size of the cryoablation ice ball after the first (10 minutes) and second freeze cycles (20 minutes) to accurately predict the size of the ice ball between first and second freezes to help prevent any unwanted damage of the nearby skin and neurovascular structures. This is especially important when ablating in relatively small body parts such as in the appendicular skeleton. Material and Methods Eight patients treated with cryoablation over a 12-month period for fibromatosis were, included in the study. The size and volume of the ice ball were measured during the first and second cycle of cryoablation. Results The average patient age of the cohort was 35.6 years old (min 28 and max 43). There was female predominance in the study (3:2, F:M). There was a significant increase (26%) in the linear dimensions and almost doubling in the volume of the ice ball between freeze cycles ( p -value = 0.0037 for dimensions and p -value = 0.0002 for volumes). Conclusion This pilot study is a preliminary attempt to predict the eventual size of the ice ball during cryoablation procedures when treating cases of fibromatosis. This should help in planning cryoablation to ensure decrease morbidity by preventing injury to adjacent critical structures (neurovascular bundle and skin).

Type 1 diabetes patient experiences and management practices during the COVID-19 pandemic in rural Uganda.

Background: The COVID-19 pandemic has impacted various aspects of the lives of persons with chronic diseases, including type 1 diabetes (T1D). However, the diabetes care experiences and practices adopted by persons living with T1D after the declaration of the COVID-19 pandemic in Uganda have not been well documented. Objectives: We investigated diabetes management practices and experiences of persons with T1D during the COVID-19 pandemic lockdown in a rural district of southwestern Uganda. Methods: Using interactive sequential explanatory mixed methods, we conducted a cross-sectional study of persons with T1D aged 18-25 years, their caregivers and health workers. Quantitative data was exclusively collected from patients with T1D using Kobo Toolbox™ and analysed with SPSS™ version 26; qualitative interviews were used to elicit responses from purposively selected patients with T1D, plus caregivers and health workers that were analysed using a thematic framework approach. Results: The study enrolled 51 (24 males) patients with T1D; diabetes duration (mean ± SD) 6.6 ± 5 years. Access to insulin syringes significantly worsened in 19.6% of participants (p = 0.03). Insulin injection frequency (p = 0.01), blood glucose monitoring (p = 0.001) and meal frequency (p = 0.0001) significantly decreased. Qualitative interviews highlighted COVID-19 restriction measures had reduced household income, frequency of clinic visits, and access to food, diabetes support and social services. Conclusions: Experiences and practices were consistent with decisions to prioritise survival, even with known risks around metabolic control.

Coexisiting type 1 diabetes and celiac disease is associated with lower Hba1c when compared to type 1 diabetes alone: data from the Australasian Diabetes Data Network (ADDN) registry.

AIM: To compare HbA1c and clinical outcomes in adolescents and young adults with type 1 diabetes (T1D), with or without celiac disease (CD). METHODS: Longitudinal data were extracted from ADDN, a prospective clinical diabetes registry. Inclusion criteria were T1D (with or without CD), ≥ 1 HbA1c measurement, age 16-25 years and diabetes duration ≥ 1 year at last measurement. Multivariable Generalised Estimated Equation models were used for longitudinal analysis of variables associated with HbA1c. RESULTS: Across all measurements, those with coexisting T1D and CD had lower HbA1c when compared to those with T1D alone (8.5 ± 1.5% (69.4 ± 16.8 mmol/mol) vs. 8.7 ± 1.8% (71.4 ± 19.8 mmol/mol); p < 0.001); lower HbA1c was associated with shorter diabetes duration (B = - 0.06; 95% CI - 0.07 to - 0.05; p < 0.001), male sex (B = - 0.24; - 0.36 to - 0.11; p < 0.001), insulin pump therapy use (B = - 0.46; - 0.58 to - 0.34; p < 0.001), coexistence of T1D and CD (B = - 0.28; - 0.48 to - 0.07; p = 0.01), blood pressure (B = - 0.16; - 0.23 to - 0.09; p < 0.001) and body mass index (B = -- 0.03; - 0.02 to - 0.04; p = 0.01) in the normal range. At last measurement, 11.7% of the total population had a HbA1c < 7.0% (53.0 mmol/mol). CONCLUSIONS: Across all measurements, coexisting T1D and CD is associated with lower HbA1c when compared to T1D alone. However, HbA1c is above target in both groups.

Accuracy of MRI scans in predicting intra-articular joint involvement in high-grade sarcomas around the knee.

Aims: Intra-articular (IA) tumours around the knee are treated with extra-articular (EA) resection, which is associated with poor functional outcomes. We aim to evaluate the accuracy of MRI in predicting IA involvement around the knee. Methods: We identified 63 cases of high-grade sarcomas in or around the distal femur that underwent an EA resection from a prospectively maintained database (January 1996 to April 2020). Suspicion of IA disease was noted in 52 cases, six had IA pathological fracture, two had an effusion, two had prior surgical intervention (curettage/IA intervention), and one had an osseous metastasis in the proximal tibia. To ascertain validity, two musculoskeletal radiologists (R1, R2) reviewed the preoperative imaging (MRI) of 63 consecutive cases on two occasions six weeks apart. The radiological criteria for IA disease comprised evidence of tumour extension within the suprapatellar pouch, intercondylar notch, extension along medial/lateral retinaculum, and presence of IA fracture. The radiological predictions were then confirmed with the final histopathology of the resected specimens. Results: The resection histology revealed 23 cases (36.5%) showing IA disease involvement compared with 40 cases without (62%). The intraobserver variability of R1 was 0.85 (p < 0.001) compared to R2 with κ = 0.21 (p = 0.007). The interobserver variability was κ = 0.264 (p = 0.003). Knee effusion was found to be the most sensitive indicator of IA involvement, with a sensitivity of 91.3% but specificity of only 35%. However, when combined with a pathological fracture, this rose to 97.5% and 100% when disease was visible in Hoffa's fat pad. Conclusion: MRI imaging can sometimes overestimate IA joint involvement and needs to be correlated with clinical signs. In the light of our findings, we would recommend EA resections when imaging shows effusion combined with either disease in Hoffa's fat pad or retinaculum, or pathological fractures.

Primary Osseous Malignancies of the Spine.

Malignant primary vertebral tumours comprise an uncommon group of primary bone malignancies that can pose a diagnostic and therapeutic challenge. The most frequently encountered malignant primary vertebral tumours include chordoma, chondrosarcoma, Ewing sarcoma and osteosarcoma. These tumours often present with nonspecific symptoms, such as back pain, neurologic deficits and spinal instability, which can be confused for the more commonly encountered mechanical back pain and may delay their diagnosis and treatment. Imaging, including radiography, computed tomography (CT) and magnetic resonance imaging (MRI) is crucial for diagnosis, staging, treatment planning and follow-up. Surgical resection remains the mainstay of treatment for malignant primary vertebral tumours, but adjuvant radiotherapy and chemotherapy may be necessary for achieving complete tumour control depending on the type of tumour. In recent years, advances in imaging techniques and surgical approaches, such as en-bloc resection and spinal reconstruction, have improved the outcomes for patients with malignant primary vertebral tumours. However, the management can be complex due to the anatomy involved and the high morbidity and mortality associated with surgery. The different types of malignant primary vertebral lesions will be discussed in this article with an emphasis on the imaging features.

A pilot randomised controlled trial assessing standard versus dermal patch-augmented rotator cuff repair found no adverse effects and suggest future trials need a minimum of 150 patients.

PURPOSE: The aims of this pilot randomised controlled trial (RCT) were to assess the safety and efficacy of a human dermal allograft patch and assess the feasibility of a future RCT comparing retear rate and functional outcome 12 months following standard and augmented double-row rotator cuff repair. METHODS:  A pilot RCT was conducted among patients undergoing arthroscopic repair of rotator cuff tear measuring between 1 and 5 cm. They were randomised to either augmented (double-row repair with human acellular dermal patch) or standard (double-row repair only). The primary outcome was rotator cuff retear determined on MRI scan at 12 months using the Sugaya's classification (grade 4 or 5). All adverse events were recorded. Functional assessment was performed at baseline and 3, 6, 9, and 12 months post-surgery using clinical outcome scores. Safety was assessed by complications and adverse effects, and feasibility by recruitment, follow-up rate and proof of concept statistical analyses of a future trial. RESULTS: Between 2017 and 2019, 63 patients were considered for inclusion. Twenty-three patients were excluded, leaving 40 patients (20 per group) in the final study population. The mean tear sizes were 3.0 cm in the augmented and 2.4 cm in the standard group. There was one adhesive capsulitis in the augmented group, with no other adverse events. Retear was observed in 4/18 (22%) of patients in the augmented and 5/18 (28%) in the standard group. In both groups, functional outcome improved significantly which was clinically meaningful for all scores, with no difference between groups. Retear rate increased with tear size. Future trials are feasible but need a minimum total sample size of 150 patients. CONCLUSION:  Clinically meaningful improved function without adverse effects was found with human acellular dermal patch-augmented cuff repairs. LEVEL OF EVIDENCE: Level II.

Blood pressure in adolescents and young adults with type 1 diabetes: data from the Australasian Diabetes Data Network registry.

AIM: Hypertension increases complication risk in type 1 diabetes (T1D). We examined blood pressure (BP) in adolescents and young adults with T1D from the Australasian Diabetes Data Network, a prospective clinical diabetes registry in Australia and New Zealand. METHODS: This was a longitudinal study of prospectively collected registry data. INCLUSION CRITERIA: T1D (duration ≥ 1 year) and age 16-25 years at last visit (2011-2020). Hypertension was defined as (on ≥ 3 occasions) systolic BP and/or diastolic BP > 95th percentile for age < 18 years, and systolic BP > 130 and/or diastolic BP > 80 mmHg for age ≥ 18 years. Multivariable Generalised Estimating Equations were used to examine demographic and clinical factors associated with BP in the hypertensive range across all visits. RESULTS: Data from 6338 young people (male 52.6%) attending 24 participating centres across 36,655 T1D healthcare visits were included; 2812 (44.4%) had BP recorded at last visit. Across all visits, 19.4% of youth aged < 18 years and 21.7% of those aged ≥ 18 years met criteria for hypertension. In both age groups, BP in the hypertensive range was associated with male sex, injection (vs. pump) therapy, higher HbA1c, and higher body mass index. CONCLUSIONS: There is a high proportion of adolescents and young adults reported with BP persistently in hypertensive ranges. Findings flag the additive contribution of hypertension to the well-established body of evidence indicating a need to review healthcare models for adolescents and young adults with T1D.

A Comparison of Magnetic Resonance Imaging and SPECT-CT Imaging in Complex Spine Pathology: Does SPECT-CT Provide Additional Diagnostic Information Over Magnetic Resonance Imaging?

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: Magnetic Resonance Imaging (MRI) is often regarded as the gold standard for spinal pathology, as it provides good structural visualisation. SPECT-CT, however, provides combined structural and functional information. There is a paucity of literature comparing SPECT-CT with MRI in the spine. Our aim was to determine whether SPECT-CT provides additional information to MRI in individuals with complex spinal pathology, including deformity, which altered management. METHODS: We conducted a retrospective review of all individuals seen at our tertiary spinal unit that were investigated with both MRI and SPECT-CT of the spine between 2007-2020. We reviewed imaging reports, and collated diagnoses, surgical treatment and the relative contributions of MRI and SPECT-CT to management decisions. RESULTS: 104 individuals identified, with a mean age of 30 years (89 females and 15 males). Diagnostic categories were adolescent, adult, and congenital deformity, degenerative pathology, and miscellaneous pathology. MRI returned positive findings in 58 (55.8%), and SPECT-CT in 41 (39.4%) cases. SPECT-CT identified 10 cases of facet joint degeneration, 5 of increased uptake around metalwork suggestive of loosening, 1 pseudoarthrosis, 1 partial failure of fusion and 1 osteoid osteoma which were not reported on MRI, all in individuals who had previously undergone spinal instrumentation. Despite this, SPECT-CT only altered management for 6 individuals (5.8%). CONCLUSIONS: MRI is less useful in the setting of previous instrumentation due to metal artefact. Where MRI is inconclusive, particularly in individuals with previous spinal instrumentation, SPECT-CT may provide a diagnosis, but is not recommended as primary imaging.

Systematic review of the effectiveness of nurse-led care in reducing glycated haemoglobin in adults with Type 1 or 2 diabetes.

BACKGROUND: Type 1 and 2 diabetes care, especially within primary health-care settings, has traditionally involved doctor-led clinics. However, with increasing chronic disease burden, there is scope for nurses to expand their role in assisting diabetes self-management. AIMS: This study aimed to determine the effectiveness of nurse-led care in reducing glycated haemoglobin in adults with Type 1 or 2 diabetes. METHODS: Methodology from the Joanna Briggs Institute Method for Systematic Review Research and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, including identifying publications, assessing study quality, summarizing evidence and interpreting findings. The search strategy involved using the Medical Subject Headings and keyword variations when searching MEDLINE (Ovid), Scopus, PubMed and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases. Inclusion criteria were samples with Type 1 or 2 diabetes, mean age of ≥18 years, English language studies and publication date of January 2011-December 2021. RESULTS: Overall, 34 articles from 16 countries met inclusion criteria. Though not always clinically significant, results indicated that nurse-led care had beneficial impacts on glycated haemoglobin values, with reductions from 0.03% to 2.0%. This was evident when nurses received formal training, used treatment algorithms, had limited medical support, utilized technology and offered defined culturally sensitive and appropriate diabetes care. CONCLUSIONS: Findings support nurse-led Type 1 and 2 diabetes care. Although further research is required, changes may necessitate increased recognition of nurse-led care and funding. Nurse-led care models should differ according to health-care settings.

Unscheduled emergency department presentations with diabetes: Identifying high risk characteristics.

BACKGROUND: Unscheduled emergency department (ED) presentation by patients with diabetes has seldom been examined. This study aimed to determine the frequency and associated characteristics of presentations in this population. METHODS: Using a prospective cross-sectional design, data were collected from patients with diabetes presenting and/or admitted to a tertiary metropolitan hospital in New South Wales, Australia (December 2016-September 2017). A screening interview including brief measures of cognitive and executive function, and clinical details from healthcare records were utilised; details around unscheduled presentations within 90 days were extracted. Independent associations with ED presentation were determined. RESULTS: Unscheduled ED presentations were common; 35.4% had at least one within 90 days, and for 20.1% this occurred within 28 days. The screening tool contributed little towards identifying risk of unscheduled presentation. Those attending any community or outpatient follow-up appointment within the first 28 (OR 0.42, 95% CI 0.23-0.76; p = 0.004) or 90 days (OR 0.25; 0.13-0.47; p < 0.001) from the index presentation were less likely to present within that same period. CONCLUSIONS: Findings indicated the magnitude of unscheduled ED presentation, care complexity and the value of targeted and timely follow-up. Alternative service support may help maintain and improve diabetes self-management and will require effectiveness and cost-effectiveness evaluation.

Recognizing the psychological impact of a glioma diagnosis on mental and behavioral health: a systematic review of what neurosurgeons need to know.

A cancer diagnosis is life altering and frequently associated with both acute and long-lasting psychosocial and behavioral distress for patients. The impact of a diffuse glioma diagnosis on mental health is an important aspect of the patient experience with their disease. This needs to be understood by neurosurgeons so these concerns can be appropriately addressed in a timely fashion and integrated into the multidisciplinary care of neuro-oncology patients. The relatively grave prognosis associated with diffuse gliomas, the morbidity associated with treatment, and the constant threat of developing a new neurological deficit all can negatively affect a patient's mental ability to cope and ultimately manifest in mental health disorders such as anxiety and depression. The objective of this systematic review was to describe the variety of behavioral health disorders patients may experience following a glioma diagnosis and discuss possible treatment options. The PubMed, Web of Science, Embase, and PsycINFO databases were searched through July 1, 2022, using broad search terms, which resulted in 5028 studies that were uploaded to Covidence systematic review software. Duplicates, non-English-language studies, and studies with irrelevant outcomes or incorrect design were removed (n = 3167). A total of 92 articles reporting behavioral health outcomes in brain tumor patients were categorized and extracted for associations with overall mental health, anxiety, depression, distress, stress, pharmacology, interventions, and mental health in caregivers. The authors identified numerous studies reporting the prevalence of mental health disorders and their negative influence in this population. However, there is a paucity of literature on therapeutic options for patients. Given the strong correlation between patient quality of life and mental well-being, there is a considerable need for early recognition and treatment of these behavioral health disorders to optimize everyday functioning for patients.

Hospital presentations with diabetic ketoacidosis: A retrospective review.

BACKGROUND: Diabetic ketoacidosis (DKA) is a significant source of preventable episodes of care and cost. This study aimed to describe the demographic and clinical characteristics of people with type 1 diabetes (T1D) presenting to the Emergency Department (ED) with DKA in an area of socio-economic deprivation in metropolitan Queensland, Australia, and to describe factors associated with hospital admission and re-presentation in this population. METHODS: This was a retrospective descriptive analysis of routine healthcare record data for January 2015-December 2019. People with T1D were identified through hospital discharge codes. RESULTS: More than half (n = 165) the estimated local T1D population (n = 317) experienced an index ED presentation for DKA; mean±SD age at ED presentation was 31.1 + /- 19.3 years, 126 (76.4%) were aged ≥ 16 years and 20 (12.1%) were newly diagnosed. Index DKA presentation was significantly associated with female sex (p = 0.04) but no other demographic or geographic variables. More than half the presentations (n = 92, 55.8%) occurred outside regular business hours. Twenty-three representations occurred within 90 days, associated with older age (p = 0.045) and lower residential socio-economic score (p = 0.02). CONCLUSION: Findings highlight the frequent problem of DKA and the importance of socio-economic influences. This flags the need and opportunity to improve support to people with T1D to promote diabetes self-care.
