154-LB: HEDIS Glycemic Goals Achieved by Control-IQ Technology Users across All Payer Types

Abstract

Background: The t:slim X2 with Control-IQ technology (“Control-IQ”) is an advanced hybrid closed-looped system. This analysis evaluated glycemic outcomes in Control-IQ users by payer type using Healthcare Effectiveness Data and Information Set (HEDIS) quality thresholds. HEDIS is used by >90% of health plans to measure performance and includes a metric to identify A1c control (<8.0%) and poor control (>9.0%). Glucose management indicator (GMI) is a recognized surrogate for A1c when sufficient data are provided (≥14 days, 70% CGM use). Methods: We retrospectively analyzed glycemic data for individuals with type 1 diabetes from 1/1/20 to 3/4/23 who used Control-IQ for ≥1 year (with ≥70% of CGM use in final 3 months) and had a recorded baseline A1c prior to Control-IQ initiation. Results were stratified by payer type, prior therapy, and baseline A1c. GMI was calculated for last 3 months and compared to baseline A1c. Results: Analysis included 20,319 users, with 42% (n= 8,493) on multiple daily injections (MDI) and 58% (n=11,826) on pump therapy at baseline. Control-IQ use significantly improved glycemic outcomes and mean HEDIS thresholds were achieved for all payer types and strata (table). Conclusion: Control-IQ use improved HEDIS A1c (GMI) outcomes across all payer types, with the largest glycemic improvement seen in those with the highest A1c at baseline and for prior MDI users.
