基于英国早期预警评分对急诊护理工作量的研究

Research on emergency nursing workload based on the national early warning score of the United Kingdom

目的探讨应用英国早期预警评分系统测量患者所需护理工时的可行性。方法调查入住急诊抢救室372例次患者的疾病严重程度和入住后8 h所需的护理工时。结果英国早期预警评分和直接护理工时评分之间呈正相关(P<0.01),优于急性生理和慢性健康状况评分;英国早期预警评分各组间的护理工时差异有统计学意义(P<0.01);两两比较低危组、极高危组分别与其他3组护理工时的差异有统计学意义(P<0.01),中危组和高危组的护理工时差异无统计学意义(P>0.05);英国早期预警评分每增加1分,直接护理工时平均增加5.90 min;患者8 h所需护理工时(min)=148.82+8.30×英国早期预警分值。结论英国早期预警评分可以快速预测护理工时,从而指导护理人力分配。

Objective To explore the relationship between the severity of the patient g condition rated by national early warning score （NEWS） and the re- quired nursing hours. Method The severity of the disease in 372 patients admitted to the emergency resuscitation room and the required nursing hours after ad- mission for 8 hours were investigated. Result There was a positive correlation between NEWS score and direct nursing hours （ P 〈 0.01 ） ,it was better than a- cute physiologic and chronic health evaluation （APACHE II） score. There were significant differences in nursing hours among different NEWS scores group （P 〈0.01 ）. There was statistical significance （P 〈0.01 ） between the low risk group and the other 3 groups,and there was no significant difference in nursing hours between the other groups （ P 〉 0.05 ）. NEWS score increased by 1 points, the average increase in nursing hours 5.90 minutes. In 8 hours the required nurs- ing time （minutes） = 148.82 ＋ 8.30 × NEWS score. Conclusion NEWS could fast prediction of nursing time so as to guide the nursing manpower allocation.
