最后一句，理解的对吗，谢谢

The present chapter reviews current and emerging payment models that, presently and in the near future, will provide economic support for the practice of spine care. Some general familiarity with the concepts of outcomes assessment and medical evidence is expected of the reader, not a high barrier, given the pervasiveness of both concepts throughout current medical training and practice [5]. We describe payment models based upon clinical outcomes achieved during the everyday care of real patients, as assessed by generic and specialized instruments such as the Patient- Reported Outcomes Measurement Information System (PROMIS) [6].We describe other payment models based upon evidence-based methods that consolidate findings in prior published studies of previous cohorts or populations exposed to the same treatment [7]. We indicate that ongoing mandates aimed to contain ever-increasing costs of care are likely to result in a convergence of the two approaches as framed through Medicare payment models such as MACRA (see below). We conclude with a glimpse into how emerging technology may accelerate the routine collection of “big” data on a large scale to inform value-based care, including the application of blockchain methodology to aggregate detailed, individual patient data to inform population-based outcomes assessment while maintaining the security and confidentiality of individual records.

整个一段话，感觉都很难，尤其是最后一句，理解的对吗， conclude该怎么翻译？谢谢

本章回顾了目前及不久的将来，为脊柱疼痛的治疗提供经济支持的当前和新兴的支付模式。考虑到无论是按服务付费还是共同承担财务风险，这两种支付模式在当前医疗培训和实践中普遍存在，读者应该对预后评估和医学证据这两个概念有一定的了解，而非一无所知[5]。我们根据患者在治疗过程中获得的临床效果来描述支付模式，效果评估借助通用及专用的工具（如PROMIS）进行[6]。我们描述了基于循证方法的其他付费模式，这些方法加强了此前发表的对相同治疗方式的队列或人群研究的结果[7]。我们指出，旨在控制不断增加的治疗成本的持续任务，可能导致通过医疗保险支付模式（如MACRA）构建的两种支付方法的趋同。最后，为向基于价值的医疗模式提供信息，我们简要介绍了一下新兴技术如何快速且大规模、“大”数据地收集信息，包括在既要保持个人记录的安全性和私密性又要为患者的预后评估提供信息的同时，如何应用区块链的方法来汇总患者的个人数据。
