OBJECTIVES: Human papillomavirus (HPV) infections are highly prevalent sexually transmitted infections, notably associated with various cancers. This study analyses the health and economic impacts of HPV-associated diseases in the Czech Republic and evaluates the cost-effectiveness of a catch-up vaccination program. METHODS: Utilizing a Markov multistate model, the study assesses the lifetime impacts and costs related to HPV infections. Cohorts of ages 15-21 were simulated to assess the impact of catch-up vaccination outside the 11-year-old age group. RESULTS: The total quality-adjusted life years (QALYs) for the female and male cohorts (together 119,362 individuals) were higher in the vaccination scenario compared to the non-vaccination scenario. The increase in QALYs was 122,246 and 200,852 respectively, when considering the actual vaccination rates. Across both cohorts, 329 cancer-related deaths were prevented. In the probabilistic sensitivity analysis for the female population, vaccination was the dominant strategy in 99.3% of iterations. In the male population, vaccination was the dominant strategy in 80.3% of iterations. The implementation of catch-up vaccination for the 15-21 age group significantly increased QALY gains and reduced life-years-lost (LYLs). In the female cohort, all analysed rates of catch-up vaccination were the dominant strategy, while in the male cohort, the incremental cost-effectiveness ratios (ICERs) remained consistently below 42,000 CZK/QALY. CONCLUSIONS: The catch-up vaccination program for 15-21-year-olds is cost-effective and can prevent a significant number of HPV-related cancers in both men and women.

OBJECTIVE: Lower limb peripheral arterial disease in the symptomatic stage has a significant effect on patients´ functional disability. Before an intervention, an imaging diagnostic examination is necessary to determine the extent of the disability. This study evaluates cost-effectiveness of duplex ultrasonography (DUS), digital subtraction angiography (DSA), computed tomography angiography (CTA) and magnetic resonance angiography (MRA) in the diagnostics of symptomatic patients with lower limb peripheral arterial disease indicated for endovascular or surgical intervention. METHODS: Discrete event simulation was used to capture lifetime costs and effects. Costs were calculated from the perspective of the health care payer, and the effects were calculated as quality-adjusted life year's (QALY's). The cost-effectiveness analysis was performed to pairwise compare CTA, MRA and DSA with DUS as the baseline diagnostic modality. A scenario analysis and probabilistic sensitivity analysis were carried out to evaluate the robustness of the results. RESULTS: In the basic case, the DUS diagnostic was the least expensive modality, at a cost of EUR 10,778, compared with EUR 10,804 for CTA, EUR 11,184 for MRA, and EUR 11,460 for DSA. The effects of DUS were estimated at 5.542 QALYs compared with 5.554 QALYs for both CTA and MRA, and 5.562 QALYs for DSA. The final incremental cost-effectiveness ratio (ICER) value of all evaluated modalities was below the cost-effectiveness threshold whereas CTA has the lowest ICER of EUR 2,167 per QALY. However, the results were associated with a large degree of uncertainty, because iterations were spread across all cost-effectiveness quadrants in the probabilistic sensitivity analysis. CONCLUSION: For imaging diagnosis of symptomatic patients with lower limb peripheral arterial disease, CTA examination appears to be the most cost-effective strategy with the best ICER value. Baseline diagnostics of the DUS modality has the lowest costs, but also the lowest effects. DSA achieves the highest QALYs, but it is associated with the highest costs.
