Diabetes Technology Use in Adults with Type 1 and Type 2 Diabetes.

In the last 2 decades, diabetes technology has emerged as a branch of diabetes management thanks to the advent of continuous glucose monitoring (CGM) and increased availability of continuous subcutaneous insulin infusion systems, or insulin pumps. These tools have progressed from rudimentary instruments to sophisticated therapeutic options for advanced diabetes management. This article discusses the available CGM and insulin pump systems and the clinical benefits of their use in adults with type 1 diabetes, intensively insulin-treated type 2 diabetes, and pregnant patients with preexisting diabetes.

Diabetes Technology in the Inpatient Setting for Management of Hyperglycemia.

In past decades, a rapid evolution of diabetes technology led to increased popularity and use of continuous glucose monitoring (CGM) and continuous subcutaneous insulin infusion (CSII) in the ambulatory setting for diabetes management, and recently, the artificial pancreas became available. Efforts to translate this technology to the hospital setting have shown accuracy and reliability of CGM, safety of CSII in appropriate populations, improvement of inpatient glycemic control with computerized glycemic management systems, and feasibility of inpatient CGM-CSII closed-loop systems. Several ongoing studies are focusing on continued translation of this technology to improve glycemic control and outcomes in hospitalized patients.

Continuous subcutaneous insulin infusion was initially developed as a research procedure in the 1970s but quickly became a routine treatment for selected people with Type 1 diabetes. Continuous subcutaneous insulin infusion and other diabetes technologies, such as continuous glucose monitoring, are now an established and evidence-based part of diabetes care, but there has been some confusion about effectiveness and best use, particularly because of conflicting results from meta-analyses. This is because literature summary meta-analyses (including all trials) are inappropriate for therapeutic and economic decision-making; such meta-analyses should only include trials representative of groups likely to benefit. For example, for continuous subcutaneous insulin infusion, this would be those with continued disabling hypoglycaemia or elevated HbA1c levels. Alternatively, individual patient data meta-analysis allows modelling of covariates that determine effect size, e.g. in the case of continuous glucose monitoring, baseline HbA1c and frequency of sensor usage. Diabetes technology is therefore an example of personalized medicine, where evaluation and use should be both appropriate and targeted. This will also apply to future technologies such as new 'patch' pumps for Type 2 diabetes, closed-loop insulin delivery systems and nanomedicine applications in diabetes that we are currently researching. These include fluorescence lifetime-based non-invasive glucose monitoring and nanoencapsulation of islets for improved post-transplant survival.
