Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Data will be collected using a standardized questionnaire. This questionnaire is based on a review of the relevant literature on diabetes management and related technologies. The final instrument consists of 37 closed-ended items. It was organized into four main sections, covering demographic characteristics, knowledge of diabetes mellitus, knowledge of insulin therapy and insulin pump use, and knowledge of CGM systems. Demographics will be also collected along with diabetes knowledge questions and 2 sections (1 for insulin pumps and 1 for continuous glucose monitoring).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Knowledge of Diabetes Mellitus aspects
Time Frame: Through study completion, an average of 1 year and 3 months
Questions on diabetes types, diagnostic criteria, risk factors for hypo- and hyperglycemia, symptom recognition, and glycemic targets.
Through study completion, an average of 1 year and 3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
knowledge on insulin use
Time Frame: Through study completion, an average of 1 year and 3 months
The instrument was a questionnaire of 37 closed ended items organized in 4 sections covering demographic characteristics, knowledge of diabetes mellitus, knowledge of insulin therapy and insulin pump use, and knowledge of CGM systems. The questions for insulin use covered the knowledge of healthcare professionals on insulin regimens, dose calculation and administration, principles and benefits of insulin pump therapy, potential complications and appropriate actions in case of device malfunction.
Through study completion, an average of 1 year and 3 months
Knowledge of healthcare professionals on continuous glucose monitoring systems
Time Frame: Through study completion, an average of 1 year and 3 months
Questions on system function, accuracy, indications for use, contribution to glycemic control, sensor placement and common issues during use.
Through study completion, an average of 1 year and 3 months

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2025

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
