We have developed an Internet-based, interactive computer model to determine the long-term health outcomes and economic consequences of implementing different treatment policies or interventions in type 1 2 diabetes mellitus. The projects for populations, taking into account baseline cohort characteristics past history complications, current future management concomitant medications, screening strategies changes physiological parameters over time. development life expectancy,...

Abstract Objectives The aim of this study was to project the long‐term costs and outcomes continuous subcutaneous insulin infusion (CSII) compared with multiple daily injections (MDI) in patients Type 1 diabetes UK. Methods CORE Diabetes Model is a peer‐reviewed, validated model which employs standard Markov/Monte Carlo simulation techniques describe incidence progression diabetes‐related complications. It used simulate disease cohort baseline characteristics taken from published UK studies...

Objective. To evaluate the cost‐effectiveness of Project Dulce, a culturally specific diabetes case management and self‐management training program, in four cohorts defined by insurance status. Data Sources/Study Setting. Clinical cost data on 3,893 persons with participating Dulce were used as inputs into simulation model. Study Design. The Center for Outcomes Research Diabetes Model, published, peer‐reviewed validated model diabetes, was to life expectancy, quality‐adjusted expectancy...

Real-world evidence has demonstrated improved glycemic control and insulin management following introduction of smart pens in a Swedish type 1 diabetes (T1D) population. To understand the implications for healthcare costs expected health outcomes, this analysis evaluated long-term cost-effectiveness introducing to standard-of-care T1D treatment (standard care) from societal perspective. Clinical outcomes (in 2018 krona, SEK) were projected over patients' lifetimes using IQVIA CORE Diabetes...

Background and aims: Effective glycemic control is the cornerstone of successful type 2 diabetes management. However, many patients fail to reach targets, therapeutic inertia (failure intensify therapy address poor in a timely manner) has been widely reported. The aim present study was evaluate economic burden associated with diabetes-related complications due for UK.Methods: A validated long-term model (IQVIA CORE Diabetes Model) used project cost outcomes UK population diabetes, based on...

Recent data have shown that type 2 diabetes patients in the UK delay initiating insulin on average for over 11 years after first being prescribed an oral medication. Using a published computer simulation model of we used UK-specific to estimate clinical consequences immediately versus delaying initiation periods line with estimates.In base case scenario simulated patients, characteristics based data, were modelled as either or 8 years. Clinical outcomes terms both life expectancy and...
