SUMMARY OF STUDY RATIONAL - Our project focuses on two populations; those with type 1 diabetes (T1D) and those with poorly controlled type 2 diabetes (T2D). Telemedicine Monitoring of Adults with Uncontrolled Diabetes Mellitus (Tele-MONITOR DM) is designed to reduce health care disparities in under resourced populations by enhancing existing telehealth visits for individuals with poorly controlled diabetes through continuous glucose monitoring (CGM) with data automatically transmitted to a clinic dashboard to allow for outreach to patients as needed in between routinely scheduled visits and feedback to primary care providers for medication management.
Few people with diabetes reach their treatment targets. This is particularly true for the under resourced who lack access to medical care who often have very high glucose levels, as well as have a risk for hypoglycemia. For our patients, part of the difficulty in accessing care is the disruption it creates in their schedule to take the time to come in for an office visit. The use of telemedicine due to the COVID pandemic has expanded our ability to reach patients in a convenient manner, based on the patient's preferences rather than a fixed clinic schedule. Use of technology has increased along with this, particularly because Medicare rules for covering technology have expanded. This allows for close monitoring and frequent medication dose adjustment to treat both hyper- and hypo-glycemia. These lessons learned during COVID create a new opportunity to expand the use of technology to underserved areas where uptake has been lagging but where the need is greatest.
Our system of monitoring, which the investigators originally called Tele-CGM will send alerts to our clinic that will allow for outreach to patients who need assistance, rather than waiting for them to contact the clinic. By looking both at the daily alerts as well as weekly data updates on each patient, the investigators should help keep patients safer, start and uptitrate guideline-recommended medications more effectively and work to encourage adherence to lifestyle and medications. Originally, the investigators had hoped to develop our Tele-CGM system to include data from all CGM systems. Unfortunately this is not currently possible. Therefore the investigators plan to work the Freestyle Libre 2. The data will be monitored through the existing LibreView system, with enhanced functionality for population management. The CGM system selected for each patient will be individualized based on the patient's preferences, clinical need for the device and insurance coverage (if available). For those without a CGM, they will be provided with a Freestyle Libre device free of charge.
If our findings prove the utility of our system, it will validate the role of treatment intensification for diabetes management in primary care, using asynchronous data collection from CGM devices by diabetes educators supervised by an endocrinologist. It will also assess the utility of a device-dashboard that will provide near real-time alerts to clinic staff so that they can respond to unusually high and low blood glucose values as well as discontinuation of sensor use.

Continuous Glucose Monitoring (CGM) Blinded Mode - A commercially available Libre Pro (for blinded mode) CGM device will be provided and a sensor will be inserted.
Data from TeleMonitor Program (using FDA approved LibreView), including frequency and types of alerts, action taken. A commercially available Libre 2 CGM device will be provided and a sensor will be inserted. The participant will receive instructions on calibration, insertions, maintenance, use, and removal of the sensor. The Libre 2 CGM is linked to the LibreView program which captures CGM data and initiates alerts based on the following parameters:
1. ≥4 hours without CGM signal
2. ≥2 hours 54 - 70 mg/dl
3. 15 minutes \<54 mg/dl Brief Patient Health Questionnaire (PHQ-8) - The PHQ-8 is an eight-item scale developed specifically to screen for depression. Each question has a choice format of the number of days in the past two weeks the question apply to them (Not at all 0-1day, Several days 2-6 days, More than half the days 7- 11 days, and Nearly every day 12-14 days). Administration time is approximately 10 minutes.
Diabetes Treatment Satisfaction Questionnaire (DTSQ) - The DTSQ assess patient satisfaction with diabetes treatment each. It is composed of eight questions, each of which is scored by patients on a scale ranging from zero (e.g., "very dissatisfied", "very inconvenient") to six (e.g., "very satisfied", "very convenient"). The questionnaire is composed of two different factors. The first factor assesses treatment satisfaction and consists of six questions (Q 1, 4, 5, 6, 7 and 8). These six questions ask about "satisfaction with current treatment", "flexibility", "convenience", "understanding of diabetes", "recommend treatment to others" and "willingness to continue", respectively. The second factor consists of two questions (Q 2 and 3), which assess the burden from hyper- and hypoglycemia, respectively (zero being "none of the time" to six being "most of the time"). Treatment satisfaction is assessed as the sum of the scores of the six questions on the first factor (total score 36), with a higher score indicating higher treatment satisfaction. Administration time is approximately 10 minutes.
Glucose Monitoring Satisfaction Survey (GMSS) - The GMSS assess treatment satisfaction with glucose monitoring devices and its impact on quality of life and other patient-reported outcomes for patients with type 1 and type 2 diabetes. It is a 15 item scale asking subjects how much they agree or disagree (Likert scale 1-5) with each statement as it pertains to their current glucose monitor. There are 4 sub-scales Openness, Emotional burden, Behavioral burden, and Trust (for type 1) Worthwhileness (for type 2). Higher scores indicate higher satisfaction. Administration time is approximately 10 minutes.
Diabetes Distress Scale for T1D (DDS T1D) - The DDS T1D is a 28-item self-report scale that highlights seven critical dimensions of distress: powerlessness, management distress, hypoglycemia distress, negative social perceptions, eating distress, physician distress, and friends/family distress. The seven sub-scales include:
Powerlessness: A broad sense of feeling discouraged about diabetes; e.g., "feeling that no matter how hard I try with my diabetes, it will never be \|good enough." Management Distress: Disappointment with the patient's self-care efforts; e.g., "feeling that I don't give my diabetes as much attention as I probably should." Hypoglycemia Distress: Concerns about hypoglycemic events; e.g., "feeling that I can't ever be safe from the possibility of a serious hypoglycemic event." Negative Social Perception Distress: Concerns about the possible negative judgments of others; e.g., "feeling like I have to hide my diabetes from other people.
Eating Distress: Concerns that the patient's eating is out of control; e.g., "feeling that thoughts about food and eating control my life." Physician Distress: Disappointment with the patient's current health care professionals; e.g., "feeling that I don't get help I really need from my diabetes doctor about managing diabetes." Friend/Family Distress: A perception that there is too much focus on diabetes amongst the patient's loved ones; e.g., "feeling that my family and friends make a bigger deal out of diabetes than they should." Higher scores indicate higher stress. Administration time is approximately 15 minutes.
Diabetes Distress Scale for T2D (DDS T2D) - The DDS T2D is a 17 item self-report scale that reflects overall diabetes distress from all sources with four sub-scales:
Emotional Burden (5 items): feeling overwhelmed, frightened or fearful about managing the demands of diabetes over time.
Regimen Distress (5 items): feeling that they are failing by not managing their diabetes well, e.g., meal plan, exercise, etc.
Interpersonal Distress (3 items): feeling that they are not receiving sufficient support for their diabetes among family and friends.
Physician Distress (4 items): worries about health care and obtaining sufficient expertise, support and direction from health care providers.
Each question is rated on a 6-point scale from (1) "not a problem" to (6) "a very significant problem." Higher scores indicate higher stress. Administration time is approximately 10 minutes.
Assessment of Sever Hypoglycemia and Diabetic Ketoacidosis -The Assessment of Severe Hypoglycemia and Diabetic Ketoacidosis is an interviewer administered survey assessing if the subject had any episodes of severe hypoglycemia and/or diabetic ketoacidosis since their last study visit. Events are recorded to assess frequency, as is type of assistance required to treat the event. Administration time is approximately 5 minutes.
