Cost Analysis of the FreeStyle Libre Systems in People with Type 2 Diabetes Mellitus on Basal Insulin with Poor Glycemic Control: A Spanish Perspective
Authors' conclusion
FreeStyle Libre could reduce acute events, chronic diabetic complications, and work absenteeism in poorly controlled patients with T2D on basal insulin, generating cost savings for the Spanish health system and society.
Study context
- Population
- Patients with T2D on basal insulin with poor glycaemic control (HbA1c >8%), Spainmodelled cohort
- Participants
- 1,000 patients
- Exposure
- Flash monitoring (FM) vs self-monitoring of blood glucose (SMBG)
- Outcome
- Annual cost per patient
- Follow-up
- Annual

- €979.706
Observational data: associations, not effects.
Further findings
| Outcome | FM | SMBG |
|---|---|---|
| Scenario including chronic diabetic complications and absenteeism (1000 patients)Value = chronic diabetic complications cost | €2,886,785 | €3,745,869 |
| Absenteeism cost | €99,004 | €237,990 |
- Scenario including chronic diabetic complications and absenteeism (1000 patients) — Annual cost savings of FM vs SMBG
- €1,997,777
Acute events averted with FM in 1000 patients
- NSHEs averted (cost FM vs SMBG: -€66,672)
- 2162
- Severe hypoglycemic events (SHEs) averted (cost FM vs SMBG: -€2,579,224)
- 1450
- Diabetic ketoacidosis (DKA) averted (cost FM vs SMBG: -€6310)
- 1.5
Sensitivity analyses
- Savings when strips/lancets free
- -€442,117
- Savings assuming lower SHE frequency (1.4 events/patient-year)
- -€321,488
- All sensitivity analyses confirmed cost savings of FM vs SMBG
