Tools for Individualizing Diabetes Care in Clinical Practice
Variables/Tools for Guiding Individualization • Individual variables • Age • Duration of diabetes • Cardiovascular disease • Mortality prediction models • Comorbidity alone (TIBI, NSHAP) • Comorbidity and functional status (HRS) • Diabetes simulation models • Decision support tools for clinical practice
Comorbidity and Functional Status Index (JAMA 2006;295(7):801-808) JAMA. 2006;295(7):801-808
Traditional Model of Diabetes Complications Advance in disease progression one year Retinopathy Module Nephropathy Module Alive Simulate natural history of diabetes progression according to patient characteristics Assign initial patient characteristics Neuropathy Module Mortality Module Coronary Heart Disease Module Dead Stroke Module Select next patient
Conceptual Framework for Personalized Decision Support Wilkinson, Nathan, Huang. Curr Diab Rep. 2013 Apr;13(2):205-12
Future Directions • Individualization of diabetes care is frequently cited but what it means varies • What is the best way to individualize care? • No clear consensus on categorization of older patients • Numerous variables to consider (life expectancy, duration of diabetes, pre-existing cardiovascular disease) • Need trials of competing algorithms and decision support tools
