The purpose of this study was to compare the incidence of functional deterioration of elderly patients hospitalized in acute care geriatric units compared to that in a conventional care unit. We performed a prospective controlled study over 9 months of patients above 65 years old with acute medical pathology. Upon discharge, we compared the degree of functional deterioration using the Katz index compared to the basal level before admission of both groups. Of the 143 patients studied, 68 were admitted to the geriatric care unit and 75 to the conventional care unit. In the geriatric unit, the incidence of functional deterioration occurred in 13 patients (19.1%), while in the conventional care unit it occurred in 30 (40%) (p=0.01). In a multivariate analysis of logistical regression, the odds ratio of developing functional deterioration at discharge in the conventional care unit, compared to the geriatric unit was 4.24 (95% CI: 1.50-11.99). The length of stay was shorter in the geriatric unit (7.5 vs. 9.92, p=0.03). We conclude that the elderly patients admitted to a geriatric care unit showed less functional deterioration on discharge compared with those kept in another care unit of a conventional type.
本研究的目的是比较入住急性护理老年病房的老年患者与入住传统护理病房的老年患者功能恶化的发生率。我们对65岁以上患有急性内科疾病的患者进行了为期9个月的前瞻性对照研究。出院时，我们使用Katz指数比较了两组患者与入院前基础水平相比的功能恶化程度。在143名研究患者中，68名入住老年护理病房，75名入住传统护理病房。在老年病房，13名患者（19.1%）出现功能恶化，而在传统护理病房，30名患者（40%）出现功能恶化（p=0.01）。在逻辑回归的多变量分析中，与老年病房相比，传统护理病房出院时出现功能恶化的比值比为4.24（95%置信区间：1.50-11.99）。老年病房的住院时间较短（7.5天对9.92天，p=0.03）。我们得出结论，与入住传统类型其他护理病房的老年患者相比，入住老年护理病房的老年患者出院时功能恶化程度较轻。
