背景 在台灣，預立遺囑還不是非常普及。因此，對於病危老年患者是否進行維生處置，多數是由其家人做決定。
目的 比較老人本身及其家人對於老人在不同健康情境時的維生決定傾向。
方法 採橫斷式比較描述性研究，研究對象包括95對社區老人及其家人。使用修改版的Life Support Preferences Questionnaire用以測量維生處置意願傾向，所得資料以paired-sample;-test進行分析。
結果 在8種不同健康情況和4種不同維生處置中（共32項），這32項家人對於維生處置的意願傾向，均高於老人對自己維生處置之意願傾向，有23項（72%)達統計顯著水準。
結論/實務應用 為了使家人的決定忠於老人本身之意願，彼此有必要針對病危時是否接受維生處置進行溝通。

Background: Written advance directives a「e not common practice in Taiwan; thus, when older adults are critically ill, family members are usually the ones to make decisions regarding life-sustaining treatment.
Purpose: This study determined how well the preferences of the family members for the olderadults match the preferences of the older adults themselves with regard to life-sustaining treatment.
Methods: A cross-sectional comparative descriptive research design was used in this study. Ninety-five pairs of older adults and their families were included in the final analysis. The Life Support Preferences Questionnaire was used to measure life-sustaining preferences. Paired-sample t tests were performed to compare the mean differences between the older adults' preferences and the family members' preferences for these older adults.
Results: Family members scored higher on life-sustaining treatment preferences than the older adults for all 32 examined items, with 23 (72%) of these items showing statistical significance.
Conclusion/Implications for Practice: Communication between older adults and their family members regarding life-sustaining treatment may help prevent older adults from receiving unwanted treatments.
