We sought to determine whether elderly patients with a serum albumin level <3.4 g/dL on admission to community hospitals have a longer duration of hospitalization than those with an admission serum albumin level > or =3.4 g/dL.
A total of 144 patients, 60 years of age or older, were consecutively admitted to our medical service for a variety of health problems. Within 4 hours of their admission, we measured serum albumin level and recorded subsequent length of hospital stay.
Length of hospital stay was inversely related to admission serum albumin level. The mean length of hospitalization was 3.85 +/- 2.55 days (+/- SD) for patients with an admission serum albumin level > or =3.4 g/dL and 6.74 +/- 4.79 days for those with an admission serum albumin level <3.4 g/dL. Three patients (6%) with admission serum albumin levels <3.4 g/dL died, but no deaths occurred in patients with an albumin level > or =3.4 g/dL.
A serum albumin level <3.4 g/dL obtained within 4 hours of hospital admission is a reliable predictor of prolonged hospital stay and death in patients 60 years of age or older.
我们试图确定社区医院入院时血清白蛋白水平<3.4 g/dL的老年患者住院时间是否比入院血清白蛋白水平>或 =3.4 g/dL的患者更长。
共有144名60岁及以上的患者因各种健康问题连续入住我们的医疗科室。入院后4小时内，我们测量了血清白蛋白水平并记录了随后的住院时间。
住院时间与入院血清白蛋白水平呈负相关。入院血清白蛋白水平>或 =3.4 g/dL的患者平均住院时间为3.85±2.55天（±标准差），入院血清白蛋白水平<3.4 g/dL的患者平均住院时间为6.74±4.79天。3名（6%）入院血清白蛋白水平<3.4 g/dL的患者死亡，但白蛋白水平>或 =3.4 g/dL的患者无死亡发生。
入院后4小时内测得的血清白蛋白水平<3.4 g/dL是60岁及以上患者住院时间延长和死亡的可靠预测指标。
