Policymakers seeking to introduce expensive national eHealth programs would be advised to study lessons from elsewhere. But these lessons are unclear, partly because a paradigm war (controlled experiment versus interpretive case study) is raging. England's $20.6 billion National Programme for Information Technology (NPfIT) ran from 2003 to 2010, but its overall success was limited. Although case study evaluations were published, policymakers appeared to overlook many of their recommendations and persisted with some of the NPfIT's most criticized components and implementation methods.
In this reflective analysis, illustrated by a case fragment from the NPfIT, we apply ideas from Ludwig Wittgenstein's postanalytic philosophy to justify the place of the "n of 1" case study and consider why those in charge of national eHealth programs appear reluctant to learn from such studies.
National eHealth programs unfold as they do partly because no one fully understands what is going on. They fail when this lack of understanding becomes critical to the programs' mission. Detailed analyses of the fortunes of individual programs, articulated in such a way as to illuminate the contextualized talk and action ("language games") of multiple stakeholders, offer unique and important insights. Such accounts, portrayals rather than models, deliver neither statistical generalization (as with experiments) nor theoretical generalization (as with multisite case comparisons or realist evaluations). But they do provide the facility for heuristic generalization (i.e., to achieve a clearer understanding of what is going on), thereby enabling more productive debate about eHealth programs' complex, interdependent social practices. A national eHealth program is best conceptualized not as a blueprint and implementation plan for a state-of-the-art technical system but as a series of overlapping, conflicting, and mutually misunderstood language games that combine to produce a situation of ambiguity, paradox, incompleteness, and confusion. But going beyond technical "solutions" and engaging with these language games would clash with the bounded rationality that policymakers typically employ to make their eHealth programs manageable. This may explain their limited and contained response to the nuanced messages of in-depth case study reports.
The complexity of contemporary health care, combined with the multiple stakeholders in large technology initiatives, means that national eHealth programs require considerably more thinking through than has sometimes occurred. We need fewer grand plans and more learning communities. The onus, therefore, is on academics to develop ways of drawing judiciously on the richness of case studies to inform and influence eHealth policy, which necessarily occurs in a simplified decision environment.
寻求引入昂贵的国家电子健康计划的政策制定者将被建议从其他地方吸取经验教训。但这些经验教训并不明确,部分原因是一场范式战争(对照实验与解释性案例研究)正在激烈进行。英国 206 亿美元的国家信息技术计划(NPfIT)从 2003 年持续到 2010 年,但总体上成功有限。尽管发表了案例研究评估报告,但政策制定者似乎忽视了其中的许多建议,并坚持了 NPfIT 中最受批评的一些组成部分和实施方法。
在这项反思性分析中,我们通过 NPfIT 的一个案例片段来说明,应用路德维希·维特根斯坦的后分析哲学思想来证明“n 为 1”案例研究的地位,并考虑为什么负责国家电子健康计划的人似乎不愿意从这些研究中吸取教训。
国家电子健康计划的展开方式部分是因为没有人完全理解正在发生的事情。当这种缺乏理解对项目的使命变得至关重要时,它们就会失败。对个别项目的详细分析,以阐明多方利益相关者的语境化对话和行动(“语言游戏”),提供了独特而重要的见解。这些描述而不是模型,既不能提供实验的统计概括(因为实验),也不能提供多地点案例比较或现实主义评估的理论概括。但它们确实为启发式概括提供了便利(即,更清楚地理解正在发生的事情),从而使关于电子健康计划复杂、相互依存的社会实践的更富有成效的辩论成为可能。国家电子健康计划最好被理解为一系列重叠、冲突和相互误解的语言游戏,而不是一个最新技术系统的蓝图和实施计划,这些语言游戏结合起来产生了一种模糊、悖论、不完整和混乱的情况。但超越技术“解决方案”并参与这些语言游戏将与政策制定者通常用来使他们的电子健康计划可管理的有限理性相冲突。这也许可以解释他们对深入案例研究报告的微妙信息的有限和有针对性的反应。
当代医疗保健的复杂性,加上大型技术计划的多个利益相关者,意味着国家电子健康计划需要比以往更多的思考。我们需要更少的宏伟计划,更多的学习社区。因此,学者们有责任开发明智地利用案例研究的丰富性来为电子健康政策提供信息和影响的方法,而电子健康政策必然是在简化的决策环境中进行的。
