北京大学人民医院超声心动图室现状与质量控制分析

Echocardiography room status and quality control analysis in Peking University People's Hospital

目的还原北京大学人民医院超声心动图室的真实工作流程,了解我院超声心动图室的压力和现状。方法采用数据挖掘技术统计和分析2015年3月1日至5月31日北京大学人民医院超声心动图室7982例患者(男性3683例;女性4299例)的检查信息和相关数据。结果门诊患者科室来源以心内科(73.1%)为主,其次为骨关节科门诊(5.2%)和血液科门诊(4.5%);同期住院患者来源中,心内科病房仅占21.6%。时间节点分析结果显示门诊患者的开具医嘱到预约时间、上机检查到完成报告时间均比住院患者时间短(P<0.001);而预约到登记时间、登记到上机检查时间分别比住院患者时间长(P<0.001)。上机操作时间分析结果显示平均每个工作单元的月诊量为317.7人次,而平均每位患者上机检查到完成检查时间仅为(6.0±4.5)min。结论在超声心动图工作流程中,门诊和住院患者时间分布存在差异;上机检查到完成报告时间住院患者较门诊患者长,间接反映住院患者病情相对复杂;上机操作时间与国际标准差距较大,反映了我院超声心动图室工作负荷大,质量控制难以保证。

Objective Objective To restore the real workflow of echocardiography room to understand the status quo and pressure of echocardiography physicians in our hospital. Methods Data mining techniques were used to analyze the examination information and relative date of 7,982 cases （male： 3, 683 and female： 4,299） from echocardiography room in our hospital from March 1, 2015 to May 31, 2015. Results Outpatients were mainly from the department of cardiology （73.15%） followed by the orthopedics department （5.2%） and the hematology department （4.5%） while inpatients from the department of cardiology were only 21.6%. Time node analysis showed that the time interval between medical advice and making an appointment, and between machine operation and report completion in outpatients were shorter than inpatients （ all P 〈 0.001 ）. The operating time analysis showed that the average monthly amount for each unit was 317.7 patient-times and average of operation time in each patient was only 6.0 ＋ 4.5 min. Conclusion In echocardiography workflow, the time distribution of outpatients are different from inpatients. The time interval between machine operation and report completion of inpatients is longer than outpatients. This reflects that the situation of inpatients is relatively complicated. There is a big gap in average operation time in each patient between ours and the international standard. This reflects that our echocardiography room is suffering heavy workload, and the quality control is difficult to be guaranteed.
