To provide evidence for intervention on secondary prevention of burns through studying the factors influencing the length of hospitalization on inpatients of burns.
Seven hundred and ninety burnt patients with cluster sampling, combined analyzing with Cox regression and factor analysis.
The influential factors on the length of hospitalization in inpatients with burns included a) how did the patients come to the hospital (X3), b) total body surface area involved (X4), c) depth of burns (X5), and d) the time before hospitalization after burnt (X6). The Cox proportional hazard model used was h(t)/h0(t) = e(-0.193 3F1 -0.617 6F2 -0.118 0F3), and the conversion model between factors Fi and original variates were F1 = -0.132X3 - 0.009X4 + 0.655X5 + 0.583X6, F2 = 0.019X3 + 0.875X4 + 0.257X5 - 0.294X6, F3 = 1.010X3 + 0.025X4 - 0.176X5 + 0.030X6. Data showed that the burnt patients had longer hospitalization time when the burns were deep, larger body surface area involved, and with longer delay before getting to the hospitals, where as the patients got cured faster when taken to the hospital by ambulances.
One of the major prognostic factors of burns was to treat the patients in time. Secondary prevention of burns must be reinforced.
通过研究影响烧伤住院患者住院时间的因素，为烧伤二级预防干预提供依据。
采用整群抽样法选取790例烧伤患者，结合Cox回归分析和因子分析。
影响烧伤患者住院时间的因素包括：a）患者来院方式（X3）；b）烧伤总面积（X4）；c）烧伤深度（X5）；d）伤后至住院的时间（X6）。所采用的Cox比例风险模型为h(t)/h0(t) = e(-0.193 3F1 -0.617 6F2 -0.118 0F3)，因子Fi与原始变量之间的转换模型为F1 = -0.132X3 - 0.009X4 + 0.655X5 + 0.583X6，F2 = 0.019X3 + 0.875X4 + 0.257X5 - 0.294X6，F3 = 1.010X3 + 0.025X4 - 0.176X5 + 0.030X6。数据显示，烧伤深度越深、烧伤面积越大、伤后至入院延迟时间越长，患者住院时间越长；而由救护车送至医院的患者康复更快。
烧伤的主要预后因素之一是及时治疗患者。必须加强烧伤的二级预防。
