The Effect of Do-It-Yourself Real-Time Continuous Glucose Monitoring on Glycemic Variables and Participant-Reported Outcomes in Adults With Type 1 Diabetes: A Randomized Crossover Trial
Authors' conclusion
Although the use of DIY-rtCGM did not improve glycemic outcomes compared with isCGM, it positively impacted several patient-reported psychosocial variables. DIY-rtCGM potentially provides an alternative, cost-effective rtCGM option.
Study context
- Population
- Adults with T1D52 completed follow-up
- Participants
- 60 adults
- Comparison
- Do-it-yourself rtCGM (DIY-rtCGM) vs intermittently scanned continuous glucose monitoring (isCGM)
- Primary endpoint
- Time in range (TIR) (3.9-10 mmol/L)
Methodological details8-week periods, 4-week washout on isCGM
- 8-week periods
- 4-week washout on isCGM

| Outcome | DIY-rtCGM | isCGM | P value |
|---|---|---|---|
| Hypoglycemia Fear Survey total scoreSignificantly higher with DIY-rtCGM | 1.17 ± 0.52 | 0.97 ± 0.54 | P = 0.02 |
| Fear of hypoglycaemia scoreSignificantly higher with DIY-rtCGM | 1.18 ± 0.64 | 0.97 ± 0.45 | P = 0.02 |
| Diabetes Treatment Satisfaction Questionnaire status (DTSQS) scoreHigher with DIY-rtCGM | 28.7 ± 5.8 | 26.0 ± 5.8 | P = 0.04 |
| Diabetes-related quality of life (DAWN2 Impact of Diabetes score)Slightly lower with DIY-rtCGM | 3.11 ± 0.4 | 3.32 ± 0.51 | P = 0.045 |
Sleep quality
- Sleep quality did not differ between the two groups
