The Impact of Telemedicine Interventions Involving Routine Transmission of Blood Glucose Data with Clinician Feedback on Metabolic Control in Youth with Type 1 Diabetes: A Systematic Review and Meta-Analysis

Rayzel Shulman; Clodagh S. O'Gorman; Mark R. Palmert

Our objective was to determine the impact of telemedicine (TM) interventions on the management of type 1 diabetes (T1DM) in youth. We performed a systematic review of randomized trials that evaluated TM interventions involving transmission of blood glucose data followed by unsolicited scheduled clinician feedback. We found no apparent effect of the TM interventions on hemoglobin A1c (HbA1c), severe hypoglycemia, or diabetic ketoacidosis. The limited data available on patient satisfaction, quality of life, and cost also suggested no differences between groups. It is unlikely that TM interventions, as performed in the assessed studies, had a substantial effect on glycemic control or acute complications. However, it remains possible that there are other benefits of TM not adequately reported, that newer TM strategies may be more effective and that interventions may benefit subgroups of youth, such as those with the poor glycemic control, adolescents, or those living in remote areas.

Objective To describe adverse events in pediatric insulin pump users since universal funding in Ontario and to explore the role of socioeconomic status and 24-hour support. Research design and methods Population-based cohort study of youth (<19 years) with type 1 diabetes (n=3193) under a universal access program in Ontario, Canada, from 2006 to 2013. We linked 2012 survey data from 33 pediatric diabetes centers to health administrative databases. The relationship between patient and center-level characteristics and time to first diabetic ketoacidosis (DKA) admission or death was tested using a Cox proportional hazards model and the rate of diabetes-related emergency department visits and hospitalizations with a Poisson model, both using generalized estimating equations. Results The rate of DKA was 5.28/100 person-years and mortality 0.033/100 person-years. Compared with the least deprived quintile, the risk of DKA or death for those in the most deprived quintile was significantly higher (HR 1.58, 95% CI 1.05 to 2.38) as was the rate of diabetes-related acute care use (RR 1.60, 95% CI 1.27 to 2.00). 24-hour support was not associated with these outcomes. Higher glycated hemoglobin, prior DKA, older age, and higher nursing patient load were associated with a higher risk of DKA or death. Conclusions The safety profile of pump therapy in the context of universal funding is similar to other jurisdictions and unrelated to 24-hour support. Several factors including higher deprivation were associated with an increased risk of adverse events and could be used to inform the design of interventions aimed at preventing poor outcomes in high-risk individuals.

Is the Frequency of Ketoacidosis at Onset of Type 1 Diabetes a Child Health Indicator That is Related to Income Inequality

Elizaveta Limenis; Rayzel Shulman; Denis Daneman

A recently published systematic review identifies a number of patient-, family-, physician-, and disease-related factors that account for the presence of diabetic ketoacidosis (DKA) at the onset of disease in children and youth (1). We propose a unifying hypothesis for these factors that the frequency of DKA at disease onset may be related to income inequality. Income inequality is defined as the difference in average incomes between a nations highest and lowest income earners (2). Wilkinson and Pickett (2) have provided compelling evidence that income inequality is a major determinant of health and social outcomes in the worlds most advanced countries. Health indicators such as infant mortality and low birth weight have been found to be less favorable in nations where income inequality is greater (2). We …

Resources and population served: a description of the Ontario Paediatric Diabetes Network

Rayzel Shulman; Fiona A. Miller; Therese A. Stukel; Denis Daneman; Astrid Guttmann

BACKGROUND The Network of Ontario Pediatric Diabetes Programs was established in 2001 to provide access to specialized pediatric diabetes care. Universal funding for pediatric insulin pump therapy has been available in Ontario since 2006. The objective of this study was to describe the distribution of patients, resources and insulin pump use across centres within the network, now called the Ontario Paediatric Diabetes Network. METHODS We conducted a cross-sectional survey in 2012 of the 35 pediatric diabetes centres in Ontario to measure centre characteristics, patient volume and available clinical and social resources. We used health administrative data from the provincial Assistive Devices Program to describe patients aged 18 years or less using insulin pumps by centre as a measure of technology uptake. RESULTS All 35 centres participated, reporting a total of 6676 children with type 1 diabetes and 368 with type 2 diabetes. Most (> 80%) children with type 1 diabetes were followed at tertiary (n = 5) or large community (n = 14) centres. Nursing patient load was similar between centre types, but there was a large range across centres within any type. Overall, percent insulin pump use was 38.1% and varied widely across centres (5.3%-66.7%). Funded 24-hour support for pump users was available at 5 (36%) small community centres, 3 (19%) large community centres and 2 (40%) tertiary centres. INTERPRETATION Our study showed differences in access to specialized and after-hours care for children with diabetes in Ontario. Pump use varied widely across centres. Further research is needed to assess the impact of these observed differences on quality of care and outcomes.

IntroductionCommon features of autoimmune polyendocrinopathy-candidiasis-ectodermal dysplasia include candidiasis, hypoparathyroidism and hypoadrenalism. The initial manifestation of autoimmune polyendocrinopathy-candidiasis-ectodermal dysplasia may be autoimmune hepatitis, keratoconjunctivitis, frequent fever with or without a rash, chronic diarrhea, or different combinations of these with or without oral candidiasis.Case presentationWe discuss a profoundly affected 2.9-year-old Caucasian girl of Western European descent with a dramatic response to immunosuppression (initially azathioprine and oral steroids, and then subsequently mycophenolate mofetil monotherapy). At four years of follow-up, her response to mycophenolate mofetil is excellent.ConclusionThe clinical features of autoimmune polyendocrinopathy-candidiasis-ectodermal dysplasia may continue for years before some of the more common components appear. In such cases, it may be life-saving to diagnose autoimmune polyendocrinopathy-candidiasis-ectodermal dysplasia and commence therapy with immunosuppressive agents. The response of our patient to immunosuppression with mycophenolate mofetil has been dramatic. It is possible that other patients with this condition might also benefit from immunosuppression.

Valuing technology: A qualitative interview study with physicians about insulin pump therapy for children with type 1 diabetes

Rayzel Shulman; Fiona A. Miller; Denis Daneman; Astrid Guttmann

Insulin pumps for children with type 1 diabetes have been broadly adopted despite equivocal evidence about comparative effectiveness. To understand why and inform policy related to public funding for new technologies, we explored how physicians interpret the value of pumps. We conducted open-ended, semi-structured interviews with 16 physicians from a pediatric diabetes network in Ontario, Canada, and analyzed the data using interpretive description. Respondents recognized that pumps fell short of expectations because they required hard work, as well as family and school support. Yet, pumps were valued for their status as new technologies and as a promising step in developing future technology. In addition, they were valued for their role within a therapeutic relationship, given the context of chronic childhood disease. These findings identify the types of beliefs that influence the adoption and diffusion of technologies. Some beliefs bear on hopes for new technology that may inappropriately hasten adoption, creating excess cost with little benefit. On the other hand, some beliefs identify potential benefits that are not captured in effectiveness studies, but may warrant consideration in resource allocation decisions. Still others suggest the need for remediation, such as those bearing on disparity in pump use by socioeconomic status. Understanding how technologies are valued can help stakeholders decide how to address such beliefs and expectations in funding decisions and implementation protocols.

BACKGROUND Children with diabetes mellitus in low-income families have poor outcomes, but little is known as to how this relates to healthcare system structure. Our objective was to gain insight into how best to structure health systems to serve these children by describing their health care use in 2 health system models: a Canadian model, with an organized diabetes care network that includes generalists, and an American model, with targeted support services for children from low-income families. METHODS We performed a population-based retrospective cohort study involving children aged 1-17 years with type 1 diabetes mellitus. We used administrative data from between 2009 and 2012 from the California Childrens Services program and Ontario. We used Ontario Drug Benefit Program enrolment to identify children from low-income families. Proportions of children receiving 2 or more routine diabetes visits per year were compared using χ2 tests, and diabetes-complication hospital admission rates were compared using direct standardization. RESULTS More California children from low-income families (n = 4922) received routine care for diabetes from pediatric endocrinologists (63.9% v. 26.9%, p < 0.001) and used insulin pumps (22.8% v. 16.4%, p < 0.001) than Ontario children (n = 2050).California children from low-income families were less likely than Ontario children to receive 2 visits for routine diabetes care per year (64.7% v. 75.7%, p < 0.001), and had slightly higher per-patient year hospital admission rates for diabetes complications (absolute differences 0.02, 95% confidence interval [CI] 0.02-0.02, for boys; 0.03, 95% CI 0.03-0.03, for girls). INTERPRETATION Ontario children from low-income families received more routine diabetes care than did California children from low-income families. Both groups of children had clinically comparable rates of hospital admission for diabetes complications. Diabetes care networks that integrate generalists may play a role in improving access and outcomes for the growing population of children with diabetes.
