「唐氏症篩檢」常因資訊繁雜、門診時間有限，造成醫病溝通痛點。本院意識到資訊「看得懂」的重要性，故以服務設計與人因工學為核心，開發圖文清晰的「病人決策輔助工具」及結構化流程，讓孕婦能充分了解並參與決策。

此導入策略成效顯著：孕婦對篩檢差異的理解率從65%提升至 92%，決策滿意度亦從3.8分上升至4.6分。對醫護端而言，優化後的工具及資訊系統整合QR Code，有效減少重複口述，使醫病討論更聚焦，大幅提升了溝通效率。本案例成功展現了系統化導入醫病共享決策的策略能有效提升孕產照護的溝通品質，深化醫病互信，是機構推行病人安全與品質提升的傑出表現。

Down syndrome screening often presents communication challenges because the condition is complex and outpatient consultation time is limited. To ensure that information is understandable to patients, this study adopted service design principles and human factors engineering to develop a clear visual patient decision aids and a structured shared decision making(SDM) workfow. This approach enabled pregnant women to better understand available screening options and actively participate in decision making. Following implementation, understanding of screening diferences among pregnant women increased from 65% to 92%, and decision satisfaction improved from 3.8 to 4.6. For healthcare providers, the optimized decision aid and integration of digital access via QR codes reduced the need for repeated explanations, allowing for more focused and efcient discussions. This study demonstrates that a systematic SDM strategy can substantially enhance communication quality in perinatal care, strengthen patient–provider trust, and support patient safety and care quality.
