A novel telemedicine protocol improved outcomes for high-risk patients with type 1 diabetes: A 3-month quality improvement project during the COVID-19 pandemic

Our endocrinology practice needed to protect its highest-risk patients with type 1 diabetes (T1D) during the COVID-19 pandemic. To do so, we needed to identify these patients and develop a protocol to keep them out of the hospital (to limit risk of infection and conserve medical resources), and do so without in-person visits. So we used our peer-reviewed software, Diabetes Reporting, to identify 87 patients whose glucose management indicator (GMI) scores were over 9%. The GMI is a method for estimating the laboratory A1C using the patient's actual blood glucose measurements over the past 90 days. A GMI (or A1C) over 9% indicates a heightened risk of diabetic ketoacidosis (DKA) and, possibly, a slightly higher risk of severe hypoglycemia (SH), the two most common acute complications leading patients with T1D to be hospitalized. We contacted these 87 at-risk patients and enrolled them in a quality improvement project. This project consisted of additional online meetings with their doctors as well as weekly reports generated by Diabetes Reporting for three months, between March 28, 2020 and June 28, 2020. We hypothesized that this heightened communication would reduce the incidence of DKA and SH among the participants by reducing their GMI. As a comparison group, we used data from the T1D Exchange, which showed that, among patients with an A1C over 9%, 6.7% were hospitalized for DKA and 7% experienced SH leading to loss of consciousness in a three-month period. This led us to predict 6 incidences of DKA and 6 incidences of SH among our 87 participants during the three-month period. Instead, we saw 2 incidences of DKA and 1 incidence of SH. Moreover, the mean GMI of our participants dropped from 9.91% to 9.25%, a clinically-significant 0.66% improvement, which supports the conclusion that our protocol helped avoid acute complications among a cohort of at-risk patients with T1D by improving glycemic control during a time when we were limited to largely online care. This telemedicine protocol merits further research for its potential to improve and lower costs of care for patients with T1D, particularly for those at higher risk for acute complications.
