Trial summary

More than 25% of the patients admitted in the general wards have a history of Diabetes Mellitus (DM). Up to 30% of the hospitalized diabetics develop hypoglycemia (low glucose values); a condition that is associated with seizures, cardiac arrhythmias, and even death. Read more about this study

About this study

Official title: Continuous Glucose Monitoring in Insulin Treated Hospitalized Veterans With DM2 at Higher Risk for Hypoglycemia

More than 25% of the patients admitted in the general wards have a history of Diabetes Mellitus (DM). Up to 30% of the hospitalized diabetics develop hypoglycemia (low glucose values); a condition that is associated with seizures, cardiac arrhythmias, and even death. In Veterans, the prevalence is disproportionally higher. It is estimated that 40-50% of hospitalized Veterans are diabetics. In this clinical trial the investigators describe the development of a novel system, the Glucose Telemetry System (GTS), with which glucose values can be wirelessly transmitted from the patient's bedside to a monitor device at the nursing station. The goal of this work is to develop a more effective glucose surveillance system at the general wards, which can decrease hypoglycemia in the hospital and improve clinical outcomes.

Read the detailed description

More than 25% of patients admitted to general wards/non Intensive Care Unit (non-ICU) setting have a history of Diabetes Mellitus (DM); and as for 2012, $125 billion dollars were costs associated with hospitalization of diabetics in the United States (US). Up to 30% of the hospitalized diabetics develop hypoglycemia, a condition that is associated with higher hospital charges, prolonged length of stay, and increased morbidity and mortality.

Reducing hypoglycemic events in the inpatient setting has led hospitals to develop hypoglycemia prevention policies; policies which are however limited by the infrequent Point of Care (POC) capillary blood glucose testing in the general wards. Continuous Glucose Monitoring (CGM) devices represent additional ways to monitor blood glucose levels. Only a limited number of studies have examined the use of CGM devices in the non-ICU setting. In all these studies, CGM use was found to be superior compared to POC in hypoglycemia detection. However, as the results of CGM were blinded (alarms were turned off) for both the investigators and the participants, interventions to prevent hypoglycemia were not performed. Additionally, one major limitation of CGM technology is that CGM receiver/monitor needs to be located in the patient's room, due to Bluetooth Technology signal-strength restrictions, necessitating nurses to enter frequently the patient's room in order to check CGM glucose values. In the current application, the investigators are going to evaluate whether an innovative system that the investigators call "Glucose Telemetry System" (GTS) can decrease hypoglycemia and improve clinical outcomes in hospitalized Veterans with DM2.

Discovering novel ways to monitor glucose values in the hospital setting could have a significant impact in preventing hypoglycemia in the inpatient setting- a condition that is associated with adverse clinical outcomes. The investigators believe that this proposal is highly innovative. The trial may lead to future wider use of CGM in hospitalized patients with DM who are at a higher risk for hypoglycemia, similar to the way that the investigators use cardiac telemetry for patients who are at an increased risk for developing arrhythmias.

Individual data sharing
Yes: The investigators will willingly share de-identified data to qualified investigators who wish to perform any additional analyses, including validation of results. Researchers need also to have completed Human Subjects and HIPPA training. Data will be provided after the end of the study. Study findings may also be presented at scientific meetings (such as American Diabetes Association and Diabetes Technology Society meetings). Study findings may also be presented at Medical and Endocrine Grand Rounds nationally. Final data sets (i.e demographic data, medication usage data, glucometric values) will be maintained locally (VABMC server) until enterprise-level resources become available for long term storage and access.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Decrease in hypoglycemia during the hospitalization (time frame: Through study completion-hospitalization (average length of stay at the hospital of 4-6 days)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03508934, which also lists 17 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jan 2026.
