该综述致力于综合研究共享决策（SDM）工具用于癌症筛查的有效性的证据，并探讨易受伤害人群和临床医生对SDM工具特定特点的偏好。采用混合方法收敛分离的方法，独立综合定量和定性数据。文章经过系统选择和筛选，纳入并进行关键评估的研究共计55篇。荟萃分析结果显示，与非易受伤害人群相比，衡量易受伤害人群在六个月内的决策困惑结果的亚组分析表明，SDM工具在提高知识水平、减少决策困惑和增加筛查意愿方面更为有效。定性研究结果揭示了临床医生和易受伤害人群对癌症筛查中SDM工具的复杂偏好。易受伤害人群非常偏爱包含相关信息、符合文化差异的内容和恰当的沟通策略的SDM工具。而临床医生则更喜欢能够轻松整合到他们的医疗系统中以实现高效使用，并能够根据患者的价值观有效指导癌症筛查工作的工具。考虑到患者和临床医生对SDM工具特点的复杂偏好，促进患者和临床医生在癌症筛查SDM工具的制定过程中的合作至关重要。这种合作可以确保对最佳支持双方需求和偏好的具体工具特点进行有效沟通。

This review aimed to synthesize evidence on the effectiveness of shared decision-making (SDM) tools for cancer screening and explored the preferences of vulnerable people and clinicians regarding the specific characteristics of the SDM tools. A mixed-method convergent segregated approach was employed, which involved an independent synthesis of quantitative and qualitative data. Articles were systematically selected and screened, resulting in the inclusion and critical appraisal of 55 studies. Results from the meta-analysis revealed that SDM tools were more effective for improving knowledge, reducing decisional conflict, and increasing screening intentions among vulnerable populations compared to non-vulnerable populations. Subgroup analyses showed minimal heterogeneity for decisional conflict outcomes measured over a six-month period. Insights from the qualitative findings revealed the complexities of clinicians' and vulnerable populations' preferences for an SDM tool in cancer screening. Vulnerable populations highly preferred SDM tools with relevant information, culturally tailored content, and appropriate communication strategies. Clinicians, on the other hand, highly preferred tools that can be easily integrated into their medical systems for efficient use and can effectively guide their practice for cancer screening while considering patients' values. Considering the complexities of patients' and clinicians' preferences in SDM tool characteristics, fostering collaboration between patients and clinicians during the creation of an SDM tool for cancer screening is essential. This collaboration may ensure effective communication about the specific tool characteristics that best support the needs and preferences of both parties.
