自2010年以來,美國亞裔已成為美國人口增長最快的族裔。美國人口普查局的數據報告顯示在美亞裔人口為一千九百四十萬人。目前,美國加州的亞裔人口最多,有六百一十萬,而在美國城市中,三藩市華裔所佔的比例最高,是21.4%。 當有多於一個以上族裔群體生活在一個城市,這些群體就迫切需要資源,特別是涉及到醫療護理領域,這樣多元化人口才能蓬勃發展。 護理人員和患者間的清晰溝通對於安全和高質量的醫療服務是很重要的。 與患者的關係和得到他們的信任取決於理解。 如果病人與護士,醫生不說同一種語言,那麼取得患者全面病歷、了解相關臨床資料、或在治療過程中情感投入的機會就會減少。 醫生與病人不說同一語言所產生的溝通困難並不為奇,但根據對認可醫療機構評審的聯合委員會(JCAHO)指出,一般美國人也沒有理解典型健康信息的能力,更何況那些不講英文或英文不是他們第一語言的人。 研究表明,患者和護理人員之間的溝通失敗可以導致不良事件和醫療失誤。美國國內語言的多樣化比以往大得多,並正在隨著英語能力有限的人口的迅速增長成為一個新的風險,醫療機構正著手處理。 作為三藩市電腦刀中心,我們理解具有講不同語言的護士和醫生的重要性。我們知道我們的患者需要明白醫生提出的重要建議和治療。為了更好地服務我們的患者,我們的一位護士和三位放射腫瘤科醫生都會講中英文。 李翠明(Minnie Li) 護士會講國、粵語和台山話,伍美文(Meiwen Wu) 醫生會講國、粵語,耿本楠(Alexander B.
