Identifying and Intervening on Glucose Patterns in Multivariate Data Using Block-Based Recurrence Quantification Analysis

J Diabetes Sci TechnolPublished Methodological study with in silico evaluation and outpatient feasibility study

Authors' conclusion

The BlockRQA is a powerful pattern recognition tool that may be used to identify glucose outcome patterns to guide AID dosing.

Study context

Population
Individuals with T1D using an AID system
Methodological detailsoutpatient pilot feasibility study, interim safety analysis
  • Outpatient pilot feasibility study
  • Interim safety analysis

Main finding

As reported in the abstract

  • BlockRQA+AID can improve glucose outcomes in patterns leading to hyperglycemia in silico
  • Real-world use of BlockRQA+AID to reduce hyperglycemic events (>250 mg/dL), small outpatient pilot
  • BlockRQA efficiently identifies, aggregates and scores behavioral patterns targetable for clinical intervention
  • Interim safety analysis
