About this study

Official title: Effect of the Use of Continuous Glucose Monitoring Versus Standard Glycemic Control for Insulin Therapy Adjustment and Decision Making in Noncritical Patients with Type 2 Diabetes Hospitalized in Medical and Surgical Wards.

Type 2 diabetes (T2D) is a common pathology in hospitalized patients and is associated with multiple comorbidities. Moreover, it is widely known that glycemic excursions increase hospital stay, infections, morbidity and mortality. Likewise, asymptomatic hypoglycemia and stress hyperglycemia in hospitalized patients is more frequent due to intercurrent pathology, medication, alteration of counter-regulatory hormones. Therefore, the use of continuous glucose monitoring (CGM) systems would be very useful as it allows early recognition of glycemic excursions and thus improve the management of insulin therapy. The primary objective is to demonstrate the increase in time in range (TIR) with the use of CGM for insulin therapy adjustment in hospitalized patients with T2D during their admission. The investigators randomized, parallel group, 2-arm, 40 participants; 20 in each group, patients with diagnosis of T2D prior to admission.

Read the detailed description

Over the past few decades advances in diabetes technology have revolutionized patient care and metabolic control. The use of CGM has demonstrated substantial benefits on glycemic control in ambulatory patients compared to standard capillary blood glucose (CG) monitoring. However, in hospitalized patients, limitations on its use persist due to the lack of standardization of the data provided by CGM.

The use of CG has been the mainstay for monitoring and adjusting the treatment of hospitalized patients with diabetes. In the management for inpatients this test is commonly performed 3 to 4 times a day. However, this provides significant limitations due to its intermittent nature and the associated time burden for hospital nursing and ancillary staff for its determination.

Several studies have demonstrated that CGM detects more hyperglycemia and hypoglycemia in critically ill and non-critically ill patients. These studies have provided important information on patterns of glycemic control, with emphasis on early detection of glycemic excursions. However, there is still a need for further research to determine the efficacy of their use in glycemic adjustment, reliability in the hospital setting, and standardized protocols for their implementation and decision-making.

HYPOTHESIS The use of CGM allows an increase in TIR and improves the detection of clinically significant hypoglycemia and hyperglycemia in patients with T2D hospitalized on basal-bolus insulin therapy versus standard CG.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Experimental (Decision making guided by CGM)Device

    Also called CGM

    Patients use FSL2 and a smartphone. Libreview app will be used to assess interstitial glucose, alarms, and trend arrows, and LibreLinkUp app for research team. Concurrently, CG will be performed using the FreeStyle Optium Neo glucometer from Abbott. The nursing staff will be trained to manage and respond to alarms and trend arrows according to established protocols. The basal insulin adjustment protocol establishes with fasting and premeal targets between 140-180 mg/dL. For prandial insulin, corrective guidelines set according to each patient sensitivity factor, with additional adjustments for the intervention group based on trend arrows. The hypoglycemia alarm sets below 85 mg/dL. If activated, nursing staff will confirm the value via CG. If values are below 70 mg/dL, follow hypoglycemia protocol and if below 100 mg/dL with a descending trend arrow, 15 grams of slow-acting carbs. The hyperglycemia alarm will be set above 300 mg/dL and nurse inform investigators to make decisions.

Study groups in NCT06607224
Study groupRoleWhat they receive
Decision making guided by CGMExperimentalHospitalized patients with T2D in non-critical medical and surgical wards. The participants use FreeStyle 2-CGM and therapeutic decisions will be made based on CGM and GC parameters; with the presence of alarms for hypoglycemia or hyperglycemia activated for timely action. Blinded will be applied to patients; while the data will be open to the physicians in charge of the research in order to make daily modifications of insulin therapy. The CG controls will be of 6 points (before each meal and two hours after meals) with a standard Abbott FreeStyle Optium Neo glucometer. Basal-bolus scheme with basal insulin Glargine U-100 and prandial insulin Aspart will be used. Daily adjustments will be made based on protocol based of our department according to the international guidelines and previous research
Receives: Device: Experimental (Decision making guided by CGM)
Decision making guided by CGNo interventionHospitalized patients with T2D admitted in non-critical medical and surgical wards. The participants use FreeStyle 2-CGM with deactivated alarms. Blind will be applied for patients, nurses and physicians in charge of the investigation. Concomitant 6-point CG controls will be performed (before each meal and two hours after meals) with Abbott FreeStyle Optium Neo glucometer. Insulin therapy adjustments will be carried out by GC only. The CGM values in this group will be evaluated a posteriori. Basal-bolus schedule with basal insulin Glargine U-100 and prandial insulin Aspart will be used. Daily adjustments will be made based on protocols of our department according to the international guidelines.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The primary objective is to demonstrate the increase in TIR with the use of CGM for insulin therapy adjustment in hospitalized patients with T2D during their admission.

    -Time in range (TIR) reported at the end of sensor use: results will be expressed in percentages and levels greater than 70% will be considered good glycemic control.

    Measured: The days of sensor use during hospitalization (from 3 to 14 days).
