Several countries mandate informed or shared decision-making for low-dose CT (LDCT) lung cancer screening, but knowledge is limited about the type of information and presentation techniques used to support decision-making in practice. This review aimed to characterize the content, format, mode, and presentation methods of decision support tools (DSTs) for LDCT lung cancer screening. DSTs reported within peer-reviewed articles (January 2000-April 2021) were identified systematically from PubMed, PsycInfo, EMBASE, and CINAHL Plus. Inclusion criteria revolved around the development or evaluation of a resource or tool intended to support individual or shared decision-making for LDCT lung cancer screening. The data-charting and extraction framework was based on the International Patient Decision Aids Standards instrument and Template for Intervention Description and Reporting. Extracted data were organized within two categories: (1) study characteristics and context, format, and mode of DST use and (2) DST content and presentation methods. This review identified 22 DSTs in paper, video, or electronic formats across 26 articles. Most DSTs (n = 13) focused on knowledge exchange, whereas seven used interactive techniques to support values clarification (eg, Likert scales) and nine DSTs guided deliberation (eg, suggested discussion topics). The DSTs addressed similar topics, but the detail, quantification of probability, and presentation methods varied considerably. None described all the potential screening harms and results. The heterogeneity in DST design may affect the quality of decision-making, particularly for participants with lower literacy and numeracy. Evidence-based consensus guidelines for DST content and presentation methods should be developed collaboratively with screening-eligible adults.

一些国家要求对低剂量 CT (LDCT) 肺癌筛查进行知情或共同决策，但对于用于支持实践决策的信息类型和演示技术的了解有限。本综述旨在描述LDCT肺癌筛查决策支持工具（DST）的内容、格式、模式和呈现方法。同行评审文章（2000 年 1 月至 2021 年 4 月）中报告的 DST 是从 PubMed、PsycInfo、EMBASE 和 CINAHL Plus 中系统识别的。纳入标准围绕着资源或工具的开发或评估，旨在支持 LDCT 肺癌筛查的个人或共同决策。数据图表和提取框架基于国际患者决策辅助标准工具和干预描述和报告模板。提取的数据分为两类：(1) 研究特征和 DST 使用的背景、格式和模式；(2) DST 内容和呈现方法。本次审查在 26 篇文章中确定了 22 个纸质、视频或电子格式的 DST。大多数 DST（n = 13）侧重于知识交流，而 7 个使用互动技术来支持价值观澄清（例如，李克特量表），9 个 DST 引导审议（例如，建议的讨论主题）。DST 涉及类似的主题，但细节、概率的量化和呈现方法有很大差异。没有人描述所有潜在的筛查危害和结果。DST 设计的异质性可能会影响决策的质量，特别是对于读写能力和计算能力较低的参与者而言。应与符合筛查资格的成年人合作制定夏令时内容和演示方法的循证共识指南。
