Introduction: A timely diagnosis of osteoporosis is key to reducing its growing clinical and economic burden. Radiofrequency Echographic Multi Spectrometry (REMS), a new diagnostic technology using an ultrasound approach, has been recognized by scientific associations as a facilitator of patients' care pathway. We aimed at evaluating the costs of REMS vs. the conventional ionizing technology (dual-energy X-ray absorptiometry, DXA) for the diagnosis of osteoporosis from the perspective of the Italian National Health Service (NHS) using a cost-minimization analysis (CMA).
Methods: We carried out structured qualitative interviews and a structured expert elicitation exercise to estimate healthcare resource consumption with a purposeful sample of clinical experts. For the elicitation exercise, an Excel tool was developed and, for each parameter, experts were asked to provide the lowest, highest and most likely value. Estimates provided by experts were averaged with equal weights. Unit costs were retrieved using different public sources.
Results: Considering the base-case scenario (most likely value), the cost of professionals amounts to €31.9 for REMS and €48.8 for DXA, the cost of instrumental examinations and laboratory tests to €45.1 for REMS and €68.2 for DXA. Overall, in terms of current costs, REMS is associated with a mean saving for the NHS of €40.0 (range: €27.6-71.5) for each patient.
Conclusions: REMS is associated with lower direct healthcare costs with respect to DXA. These results may inform policy-makers on the value of the REMS technology in the earlier diagnosis for osteoporosis, and support their decision regarding the reimbursement and diffusion of the technology in the Italian NHS.
Introduction: In recent years, target therapies to specific molecular alterations in advanced non-small cell lung cancer (NSCLC) have been identified and have shown superior efficacy compared to non-targeted treatments. Anaplastic lymphoma kinase (ALK) is one of the therapeutic targets; nevertheless, ALK diagnosis is not performed in all NSCLC patients in Spain. The objective of this study is to estimate in monetary terms the benefit for the Spanish society of ALK diagnosis in advanced NSCLC patients.
Methods: A cost-benefit analysis of ALK diagnosis vs. non-diagnosis in advanced NSCLC patients was carried out from the Spanish social perspective, with a time horizon of 5 years. Costs, benefits and the cost-benefit ratio were measured. The analysis has considered the overall survival in advanced NSCLC patients treated with the ALK-tyrosine kinase inhibitor (TKI) alectinib. The natural history of NSCLC was simulated using a Markov model. A 3% discount rate was applied to both costs and benefits. The result was tested using a deterministic sensitivity analysis.
Results: The cost of ALK diagnosis vs. non-diagnosis in the base case would be €10.19 million, generating benefits of €11.71 million. The cost-benefit ratio would be €1.15. In the sensitivity analysis, the cost-benefit ratio could range from €0.89 to €2.10.
Conclusions: The results justify the universal application of ALK diagnosis in advanced NSCLC, which generates a benefit for Spanish society that outweighs its costs and allows optimal treatment with targeted therapies for these patients.
