To determine and analyze the influence of age, gender, and ethnicity in the length of stay (LoS) of inpatient rehabilitation unit patients after stroke.
All patients who completed the stroke rehabilitation program at Sultan Bin Abdulaziz Humanitarian City, Riyadh, Kingdom of Saudi Arabia from 1st January 2005 to 15th October 2008 were selected for the study. Admission records of 823 (male; 551, female; 272) patients with a mean age of 62.87 +/- 0.54 years were included in this study. Patients aged less than or equal to 19 and more than than or equal to 91 years were excluded due to small sample size. Age, gender, and ethnic differences of LoS were analyzed.
The mean LoS on the stroke rehabilitation program of the study population was 45 +/- 1.56 days. Results showed that the frequency of the stroke was higher in the 51-60, 61-70, and 71-80 age groups, and lower in the 20-30 and 31-40 age groups. The LoS of males were longer than females in all age groups, and statistically significant results were observed in the 51-60 (p=0.0084), 61-70 (p=0.0042), and 71-80 (p=0.037) age groups as compared with females. The study also found that the LoS of Saudi patients were higher when compared with non-Saudis (p=0.0009).
The results of the study suggest that gender, age, and ethnic differences were risk factors of LoS of stroke patients.
确定并分析年龄、性别和种族对中风后住院康复科患者住院时间（LoS）的影响。
选取2005年1月1日至2008年10月15日在沙特阿拉伯王国利雅得苏丹·本·阿卜杜勒阿齐兹人道主义城完成中风康复项目的所有患者进行研究。本研究纳入了823例患者（男性551例，女性272例），平均年龄为62.87±0.54岁。由于样本量小，排除了年龄小于或等于19岁以及大于或等于91岁的患者。分析了LoS的年龄、性别和种族差异。
研究人群中风康复项目的平均LoS为45±1.56天。结果显示，中风发生率在51 - 60岁、61 - 70岁和71 - 80岁年龄组较高，在20 - 30岁和31 - 40岁年龄组较低。在所有年龄组中，男性的LoS均长于女性，与女性相比，在51 - 60岁（p = 0.0084）、61 - 70岁（p = 0.0042）和71 - 80岁（p = 0.037）年龄组观察到具有统计学意义的结果。该研究还发现，与非沙特患者相比，沙特患者的LoS更高（p = 0.0009）。
该研究结果表明，性别、年龄和种族差异是中风患者LoS的危险因素。
