Adaptive Willingness-to-Pay Thresholds: A Contextual Calibration Model

Current CEAs (e.g., Feng et al.'s statin study in China) use rigid WTP thresholds, leading to paradoxes where life-saving rare disease drugs (Rubin et al.'s cystic fibrosis case) are deemed unaffordable while marginally effective oncology drugs pass. This research develops a "Contextual WTP Algorithm" that calibrates thresholds based on: (a) disease severity/untreated mortality, (b) availability of alternatives, and (c) societal priority weights. Inspired by Zechmeister-Koss’s call for broader HTA methods, it would incorporate equity weights (e.g., higher WTP for diseases affecting young populations or marginalized groups). This directly responds to conflicts in Source 2 (oral semaglutide) and Source 4 (HPV vaccine), where the same intervention might be cost-effective in one setting but not another purely due to arbitrary thresholds.
