目的运用圆形分布法分析2011年-2015年普儿科门急诊量及收入院高峰期规律。方法数据来自于广东省医疗机构病案统计管理系统中门急诊工作报表、住院报表,采用EXCEL2007软件的圆形分布指标,采用Rayleigh’s和Watson-William检验方法进行统计学分析。结果2011年-2015年圆形分布门急诊r1=0.0963,平均角ā1=169.85°(45.91°,293.79°)(Rayleigh’s检验:P<0.01);收入院r2=0.1047,平均角ā2=173.54°(51.81°,295.27°)(Rayleigh’s检验:P<0.01)。5年门急诊量平均角比较差异F1=1268.48、收入院平均角F2=47.01,有统计学意义(Watson-William检验:P<0.01),表明各年度门急诊量及收入院高峰出现的时间不同,高峰期长短和起止时间不同。5年门急诊高峰期在2月16日-10月25日,收入院高峰期在2月22日到10月26日。结论应用圆形分布法可了解患儿就诊及收入院的时间分布规律,为医院管理提供有利的参考。
Objective To analyze the regular department of emergency department and the law of income peak during 2011-2015 by circular distribution method. Methods Data were from the outpatient and emergency work report and inpatient report of medical records management system of Guangdong Province. The circular distribution index of EXCEL2007 software was used and the statistical analysis was made by Rayleigh’s and Watson-William test methods. Results The average incidence of r = 0. 0963 and average angle ā1 = 169.85 ° (Rayleigh’s test: P <0.01) in the round-outpatient and emergency department from 2011 to 2015; r2 = 0.1047 and average angle ā2 = 173.54 ° 51.81 °, 295.27 °) (Rayleigh’s test: P <0.01). The mean difference of outpatient and emergency department in five years was F1 = 1268.48, and the average hospital income F2 = 47.01 (Watson-William test: P <0.01) , The peak period and the starting and ending time are different. The 5-year outpatient and emergency department peak period is from Feb. 16 to Oct. 25, and the income peak period is from Feb. 22 to Oct. 26. Conclusion The method of circular distribution can be used to understand the distribution of time in the treatment of infants and the income of hospital and provide a favorable reference for the hospital management.
