概括
混合尼尔塞维马布和RSVpreF免疫策略对婴儿来说在社会上具有成本效益. 然而,从医疗保健的角度来看,这种混合策略和单独的nirsevimab既没有证明与没有免疫接种相比具有成本效益.
科学领域:
- 儿科传染病儿童传染病
- 卫生经济学 卫生经济学
- 公共卫生政策 公共卫生政策
背景情况:
- 免疫实践咨询委员会 (ACIP) 建议在2023年为婴儿提供nirsevimab,并为孕妇提供RSVpreF疫苗.
- 这些建议旨在预防婴儿患有呼吸道同胞病毒 (RSV) 相关的下呼吸道感染.
- 对健康,低风险婴儿的这些策略的成本效益需要评估.
研究的目的:
- 为了比较ACIP推的混合nirsevimab和RSVpreF免疫策略的成本效益与美国健康,低风险婴儿的nirsevimab-only免疫策略.
- 从医疗保健部门和社会角度分析结果.
主要方法:
- 使用嵌套马尔科夫模型的决策树来比较三个免疫策略:没有免疫,混合策略和仅使用nirsevimab.
- 通过使用经质量调整的寿命年 (QALYs) 估计了健康和社会结果.
- 从医疗保健和社会角度评估成本,包括护理人员的生产力损失. 使用增量成本效益比率 (ICERs) 确定成本效益,以15万美元/QALY支付意愿门为准.
主要成果:
- 从医疗保健的角度来看,与没有免疫接种相比,混合或仅用nirsevimab的策略既不具有成本效益.
- 从社会角度来看,与没有免疫接种相比,混合策略具有成本效益 (117,848美元/QALY).
- 由于产品成本较高,单独的nirsevimab与混合策略相比没有成本效益,但如果RSVpreF不可用 ($ 134,391 / QALY),则会具有成本效益.
- 敏感性分析表明,结果对产品成本和疗效假设敏感.
结论:
- 由ACIP推的混合RSVpreF和nirsevimab策略是保护婴儿免受RSV的社会成本有效方法.
- 儿科医生和产科医生应该合作推这些RSV免疫接种.
- 需要进一步评估产品的成本和有效性.

Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
