UTOPIA: a consultation system for visit-by-visit diabetes management.

UTOPIA (UTilities for OPtimizing Insulin Adjustment) is a prototype computer system proposed to support home data analysis and therapy recommendations for the individual patient. The paper describes methods of analysis and their incorporation into an overall system design that matches the iterative practices at the physician-patient consultation from visit to visit. Four modules support home data display and comparison with clinical measurements; extraction of blood glucose trends and daily cycles using time series analysis, learning relationships between insulin adjustments and changes in time series patterns via a parametric, linear systems model; and advice generation by solving the linear equation for candidate insulin adjustments. Concepts and methods are placed in context, with a discussion of comparable and related research.
