Over the past several years, the issue of hepatitis C virus (HCV) infection in renal transplantation has generated considerable interest. With the availability of a test for HCV, some but not all physicians have advocated that all HCV-infected kidneys be discarded. An economic appraisal was carried out to examine 3 theoretical policies of organ allocation for HCV-infected kidneys: (a) discard all infected kidneys, (b) transplant infected kidneys into infected donors only, or (c) transplant regardless of HCV status. Using probabilities, costs, and patient outcomes from the literature/best estimate, a cost-utility analysis was performed. Patients free of infection transplanted with an infected organ were assigned higher treatment costs and poorer outcomes compared with all other combinations. Assuming a potential to transplant 8100 kidneys per year, option A was predicted to produce the fewest total quality-adjusted life years (QALYs) and incur the highest costs (largely due to patients left on dialysis). Option B was projected to produce the most QALYs, whereas option C incurred the lowest costs (no need to screen for HCV). The incremental cost utility of option B over C was $13,954 (present value 1990)/QALY. This economic appraisal suggests that transplanting HCV-infected kidneys into infected recipients is superior to a discard policy from both a cost and patient outcome perspective. However, other overriding factors, such as the ethical dilemma of transplanting an infected organ, must be addressed by both physician and patient/public before a consensus can be reached.
在过去几年中,肾移植中丙型肝炎病毒(HCV)感染问题引发了广泛关注。随着HCV检测方法的出现,部分而非所有医生主张丢弃所有感染HCV的肾脏。开展了一项经济学评估,以研究针对感染HCV肾脏的三种理论器官分配政策:(a)丢弃所有受感染肾脏;(b)仅将受感染肾脏移植给受感染供体;或(c)无论HCV状态如何都进行移植。利用文献中的概率、成本和患者结局/最佳估计值,进行了成本效用分析。与所有其他组合相比,接受感染器官移植但未感染的患者被赋予更高的治疗成本和更差的结局。假设每年有8100个肾脏有移植潜力,预计方案A产生的总质量调整生命年(QALY)最少,成本最高(主要是由于患者需继续接受透析)。方案B预计产生的QALY最多,而方案C成本最低(无需筛查HCV)。方案B相对于方案C增加的成本效用为每QALY 13,954美元(1990年现值)。该经济学评估表明,从成本和患者结局角度来看,将感染HCV的肾脏移植给受感染受体优于丢弃政策。然而,在达成共识之前,医生、患者/公众必须解决其他首要因素,例如移植感染器官的伦理困境。
