老年病患常有多重問題，住院中若只治療急性問題，而缺乏對老年病患全面性的評估與治療計畫，將錯失改善病人身體功能之契機。本個案介紹一位因泌尿道感染住院之老年病患，藉由周全性老年評估而提早介入其失智、譫妄、憂鬱、疼痛、營養、生活功能下降等問題，達到早期診斷、早期治療、改善預後、及全人照護之目的；並簡介周全性老年評估的內容、方式、與實證基礎。

Older patients often have complex health problems in multiple domains. In addition to traditional management of single disease, performing a comprehensive geriatric assessment (CGA) help clinicians to early detect and to intervene potential risk factors to improve functional capacity and quality of life among older adults. Here we presented a patient who was hospitalized due to a complicated urinary tract infection. Multiple problems including cognitive impairment, delirium, depression, pain, malnutrition, and functional decline were detected through CGA. Patient-centered plans were implemented through multidisciplinary team care. We also introduced the scope, brief methods, and updated evidence of CGA.
