    AbstractObjective: We sought to improve perinatal glycemic control and downstream neonatal outcomes through redesigned ambulatory management for women with insulin-requiring diabetes in pregnancy. Methods: To address gaps in perinatal glycemic management of women with insulin-requiring diabetes in pregnancy, redesigned care delivery (RCD) utilized integrated practice unit and minimally disruptive medicine concepts with incorporation of cellular-enabled glucose monitoring. Primary outcomes of RCD (N = 129) included hemoglobin A1c ([HbA1c], within RCD cohort), and gestational age (GA) at delivery, neonatal intensive care (NICU) admission, and NICU length of stay (LOS) compared with a preredesign care cohort (Pre-RCD; N = 122). Secondary outcomes included facility, payer reimbursement, and program costs. Generalized linear models assessed continuous variables while logistic regression methods assessed categorical outcomes. Results: Utilizing RCD, 92% of women with an initial HbA1c <6.5% maintained glycemic control until delivery, and 67.2% with an initial HbA1c ≥6.5% achieved delivery levels <6.5%. NICU admissions and GA-adjusted LOS decreased significantly [Pre-RCD vs. RCD: NICU admissions, 41.0% vs. 27.3%, p < 0.024; NICU LOS (95% confidence interval [CI]), 21.9 (17.1-26.6) vs. 14.6 (9.1-20.1), p = 0.045]. Every 10 days of redesigned management decreased mean NICU LOS by 1 day. Mean payer neonatal reimbursements decreased over $18,000 per delivery (p = 0.08) compared with implementation costs of $1,942 per delivery. Conclusion: Redesigned perinatal diabetes care with remote glucose monitoring demonstrated improved outcomes and value through downstream neonatal outcomes and lower payer costs. Therefore, subsequent dissemination and sustainability of similar programs' improved outcomes will likely require payer support.
