Specifically, 17.6% (n = 3) and 35.3% (n = 6) of the 17 full economic evaluation studies did not report the number of health states and the cycle length, respectively. Additionally, among all studies, four (15.4%) did not perform sensitivity analysis. Key input parameters were also underreported by relevant studies, including the dose, frequency, and consumption of haemostatic therapies (19/24), unit cost of the haemostatic therapy (16/24), average body weight of the study population (10/25), the number and unit cost of days off (14/26), and the methodology for estimating indirect costs (10/26). All studies reported direct medical costs; however, only 46% reported direct formal non-medical costs, 15% reported direct informal non-medical costs, and one study included intangible costs. Indirect costs were reported in all studies. The results generally supported the cost-effectiveness or dominance of prophylaxis over episodic treatment, emicizumab over recombinant activated factor VII (rFVIIa), and gene therapy over factor VIII (FVIII) prophylaxis and emicizumab.</p><p><strong>Conclusion: </strong>There were notable gaps, including inadequate reporting of model characteristics and input parameters, along with omission and mislabelling of cost categories. The findings underscore the urgent need for a disease-specific, standardised framework for societal cost categories and globally accessible costing datasets to enhance the consistency and transparency of economic studies in haemophilia.</p>","PeriodicalId":19770,"journal":{"name":"PharmacoEconomics Open","volume":" ","pages":"71-95"},"PeriodicalIF":2.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12796068/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145564869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
