Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Group 1: Freestyle Libre glucose monitoring (inserted into the upper arm) paired with Telehealth consultations in people with diabetes who are undergoing discharge from an acute care hospital. Each participant will be shown how to connect to video conferencing while they are in hospital and sent the link to their personal email address for a trial connection prior to discharge. All participants will be provided with training by a Diabetes Educator on insertion of the Libre sensor. The Freestyle Libre sensor will be worn for 2 weeks then changed to a new sensor. Participants will be asked to wear 2 sensors (for 1 month) during the study period. Participants will also be asked to scan the sensor prior to each main meal and before bed and record the BGLs in a diary. The glucose data will be downloaded at the end of each 2 week period.
The intervention will be conducted under the guidance of a Senior Endocrinologist with over 20 years experience in diabetes management.
Both study groups will have seven study visits over nine weeks at a teaching hospital providing tertiary level ambulatory diabetes care. Usual standard of care (outside of pandemic health directives) would be face to face visits. This study will provide information on the effectiveness of telehealth compared to standard care.
Study visits for participants randomised to Telehealth
Visit 1: Participants will be recruited prior to discharge from hospital.
Visit 2: On the day of discharge, a glucometer and an appointment for randomisation will be provided.
Visit 3: One week after discharge from hospital, participants be randomised at a face to face. If randomised to Freestyle Libre (Flash) and telehealth, participants will receive training on how to connect to videoconferencing for telehealth visits.
Visit 4 to 6: On three occasions at week 2, 3 and 5 after discharge, participants will be asked to connect for the telehealth reviews via videoconferencing. They will not attend in-person face to face appointments during this time. Telehealth consult duration will be 30-40 minutes. The consult will consist of glucose data review for the previous week, hypoglycaemia review and medication changes made as clinically indicated.
Glucose graphs will be reviewed to monitor for adherence to the scanning of the glucose sensor.
Visit 7: Seven weeks after discharge, the participant will attend a face to face end of study visit for BGL review.

Comparator / control treatment
Group 2: Standard Self Measured Blood Glucose (SMBG) monitoring using the Optium Freestyle Neo glucometer plus blinded Freestyle Libre PRO with traditional face-to-face clinic visits,
Optium Neo: People treated with insulin are asked to monitor BGLs using a glucometer. The Optium Freestyle Neo will be used by participants to limit glucose differences caused by different meter technologies. Participants will be asked to check BGLs before each main meal and before bed and record the results in a diary.
Libre PRO: The Freestyle Libre PRO checks BGLs but participants are blinded to the results. The PRO sensor will be applied by the study coordinator at face to face visits.
Visits: Participants will attend five face to face study visits after discharge from hospital at week 1, 2, 3, 5 and 7. The study visits will range from 30-40 minutes duration. Face to face study visit will consist of glucose review for the previous week (both diary and Neo download), hypoglycaemia review and medication changes made as clinically indicated. Participants will see the study coordinator and Senior Endocrinologist at each study visit.

Summary
Brief summary
Group One: Freestyle Libre blood glucose sensors and consults using telehealth
Group Two: Freestyle Libre PRO combined with Freestyle Optium Neo blood glucose finger prick monitoring and face to face study visits.

Aim: To compare Flash Libre glucose monitoring paired with Telehealth consultations versus standard SMBG monitoring with face-to-face clinic visits in people with diabetes who are undergoing discharge from hospital.

Hypothesis: That, in at least 60 people with type 1 and type 2 diabetes who are being discharged from Royal Prince Alfred Hospital (RPAH) on insulin treatment, those randomised to the Freestyle Libre (Flash) will have favourable effect on glucose levels (time in range (TIR), estimated HbA1c (eHbA1c), hypoglycaemia frequency and glucose variability) compared to the traditional finger prick BGL group over a seven week period after discharge.
