No more finger pricks? study tests CGM for faster healing of diabetic foot ulcers
NCT ID NCT06054659
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether using a continuous glucose monitor (CGM) instead of standard fingerstick testing helps people with type 2 diabetes heal foot ulcers faster. 116 adults who had been hospitalized for a diabetic foot ulcer were randomly assigned to use either a CGM or their usual fingerstick method. The researchers tracked wound healing rates and time to healing, as well as quality of life. The goal was to see if CGM, which provides constant glucose readings without fingersticks, could improve blood sugar control and wound recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Real-time continuous glucose monitoring (CGM) device
- What this could lead to
- If successful, this could show that CGM helps diabetic foot ulcers heal faster and reduces the need for painful fingerstick tests.
- What could go wrong
- This is a small, completed study with 116 participants, so results may not apply to all patients. CGM devices can be less accurate than fingersticks in some cases.

Inclusion Criteria: * Adults aged 18 and over with type 2 diabetes admitted to the hospital with diabetic foot ulceration with or without infection (cellulitis or osteomyelitis) * HbA1c \>= 8.0% at the time of enrollment * Treatment of diabetic foot ulcer with medical management and/or a single toe amputation * Patients with prior amputation at or below the ankle may be enrolled if they develop an ulceration in the foot that is not felt to be a surgical wound from prior amputation, defined as a healed surgical site for at least 6 weeks after the surgery before the onset of the new ulceration * Wound, Ischemia, foot Infection (WIfI) score of 1-3 * Duration of DFU less than 1 year * Able and willing to use continuous glucose monitoring technology independently or with the assistance of a close relative or caretaker Exclusion Criteria: * Age \< 18 years * Homelessness or anticipated to have unstable housing after discharge * A WIfI score of 4, denoting a very high risk for major amputation (above or below the knee) and very low odds of healing within 12 months * Any amputation more extensive than just a single toe during index hospitalization * Patients with type 1 diabetes * Participants enrolled in another interventional clinical trial (including during the run-in period). * Inability to participate in the informed consent process for any reason * Female subjects who are pregnant or breastfeeding at the time of enrollment in the study * Subjects planning to use CGM technology independent of the study following discharge * Subjects unwilling to wear a CGM device and/or monitor blood glucose with FBG
