危急值项目的应用评估

目的 对危急值项目的 历史数据进行分析,为持续改进危急值报告制度提供科学依据.方法 从实验室信息系统中筛选出2006年的危急值项目数据11项,经数据预处理、变换后,计算出危急值项目的 发生率、天内分布、周内分布、部门分布,评估危急值范围和周转时间.结果 危急值的发生率是1.67%,主要集中在8:00～13:00,周一、四危急值的数量比平时多,部门分布以血液科、移植病房为主.评估危急值项目的 高低值分布图后,血钾的危急值低限从3.0 mmol/L调整为2.8mmol/L,血液病病房的PLT、WBC的危急值低限分别从20×109/L,1.5×109/L调整为10×109/L、1.0×109/L.76.2%的危急值结果的实验室周转时间小于1 h.结论 定期回顾分析危急值项目的 数据,可以提高实验室及临床的工作效率和质量,满足患者的安全要求.

Application evaluation of critical value fists data

Objective Analyze the historical data of critical values lists,providing scientific evidence for continuous improvement of critical value systems.Methods Screen out critical value lists data of 2006 from laboratory information system,after pretreatment and transformation of data,calculate the percentage of critical value,and its daily distribution,weekly distribution and department distribution, evaluate the range and turnaround time for critical value.Results The rate of critical value was 1.67%.It was mainly concentrated from 8 to 13 O'clock.Monday and Thursday have more critical value than other days.From the perspective of department,the majority critical value was from hematology department and transplantation department.After the evaluation of distribution diagram of critical value range,the lower critical value limit of blood potassium was adjusted from 3.0 mmol/L to 2.8 mmol/L,the blood platelet and leukocyte counts for parlents with hematology disease were a(Ijusted from 20×109/L,1.5×109/L to 10×1O9/L,1.0×109/L respectively.The laboratory turnaround time for 76.2% critical value was less than 1 hour.Conclusion Review and analyze critical value lists data regularly can improve the work efficiency and quality for the laboratory and clinic department and better meet patients' safety needs.
