Details and patient eligibility

About

Rationale: Continuous glucose monitoring (CGM) and insulin pump therapy (CSII) have increased in utilization in the treatment of both type 1 and type 2 diabetes mellitus. Both types of devices are worn externally, with either a catheter or filament introduced into the subcutaneous space. Removal of these devices interrupts glucose monitoring or insulin delivery or both, which may have an adverse impact on patients' glucose control. Few studies have investigated the logistical and technical challenges that patients face when their insulin pump device or continuous glucose monitor (CGM) is interrupted.

Intervention: We will conduct a patient survey which seeks to identify and quantify the number of times insulin pump therapy or continuous glucose monitor has been disrupted, for what reason, how it was resolved and whether diabetes care had been adversely affected.

Objective: To determine the frequency and intensity of adverse health outcomes resulting from mandatory removal of CGM on insulin pump devices in healthcare or other settings.

Study population: Patients treated at Washington University outpatient clinics or Barnes Jewish Hospital between August 1, 2021- December 1, 2021. The study will include outpatients with diabetes mellitus who routinely utilize either CGM or insulin pump therapy or both. The target number of patients for the study will be 600, equally distributed between inpatients and outpatients, and with at least 100 having type 1 diabetes.

Study methodology: After providing consent, patients will complete an electronic questionnaire. Demographic information and diabetes history will be extracted from the patients' medical records.

Study endpoints: We will determine the incidence of disruptions to insulin pump therapy or continuous glucose monitoring in patients with diabetes mellitus as a result of hospitalization or medical test over a 1 year time period. We will also determine adverse health outcomes that resulted from device disruptions.
