1166-P: Cost Analysis of a Flash Glucose Monitoring System in Type 2 Diabetes Receiving ≥2 Insulin Doses a Day in Spain

FreeStyle Libre2 system is a sensor-based flash monitoring (FM) system, which assesses interstitial fluid glucose. The study aimed to estimate the cost associated with the use of FM compared to self-monitoring of blood glucose (SMBG) in type 2 diabetes mellitus (T2DM) population from the Spanish National Health System perspective. The cost for glucose monitoring in T2DM patients treated with ≥2 insulin doses a day was modelled. The cost estimation considered the annual resource consumption for glucose monitoring (strips, lancets and FM sensors) and clinical management of hypoglycemia episodes. Severe hypoglycemia episodes (SHE) and non-severe hypoglycemia episodes (NSHE) published event rates (2.5 and 17.0 episodes/patient/year) were considered. Event reductions associated to FM system use were applied (48.8% [SHE]; 27.7% [NSHE]), derived from REPLACE trial findings. Based on published evidence, hospital attendance was required in 20.5% of SHEs (further hospitalization in 16.0%). Daily strip and lancet-consumption in T2DM patients was fixed at 4.81 for SMBG users, and 0.2 for FM system users according the REPLACE findings. FM sensor annual consumption per patient was 26. Unitary costs (€,2019 excluding VAT) derived from national databases and literature were: €0.28/strip; €0.09/lancet; €3.09/daily FM sensor; €3,774/hospitalized SHE; €1,779/hospital-attended non-admitted SHE; €385/community attended SHE and €15/NSHE. Yearly cost was €2,779 and €2,295 per patient using SMBG or FM system, respectively. For a cohort of 1,000 T2DM patients using ≥2 insulin doses a day; 1,221 SHEs (48 hospitalizations for SHE) and 4,715 NSHEs, yearly could be avoided with FM use. The use of the FM system in 1,000 patients could generate annual cost-savings up to €483,031 compared to SMBG (-17.4% of cost reduction). In conclusion, FM system is a potential cost-saving strategy in T2DM patients treated with ≥2 insulin doses a day, in Spain. Disclosure F.
