The aim of this study was to evaluate all aspects of workflow in a large academic MRI department to determine whether process improvement (PI) efforts could improve key performance indicators (KPIs).
KPI metrics in the investigators' MR imaging department include daily inpatient backlogs, on-time performance for outpatient examinations, examination volumes, appointment backlogs for pediatric anesthesia cases, and scan duration relative to time allotted for an examination. Over a 3-week period in April 2011, key members of the MR imaging department (including technologists, nurses, schedulers, physicians, and administrators) tracked all aspects of patient flow through the department, from scheduling to examination interpretation. Data were analyzed by the group to determine where PI could improve KPIs. Changes to MRI workflow were subsequently implemented, and KPIs were compared before (January 1, 2011, to April 30, 2011) and after (August 1, 2011, to December 31, 2011) using Mann-Whitney and Fisher's exact tests.
The data analysis done during this PI led to multiple changes in the daily workflow of the MR department. In addition, a new sense of teamwork and empowerment was established within the MR staff. All of the measured KPIs showed statistically significant changes after the reengineering project.
Intradepartmental PI efforts can significantly affect KPI metrics within an MR imaging department, making the process more patient centered. In addition, the process allowed significant growth without the need for additional equipment or personnel.
本研究旨在评估大型学术性磁共振成像(MRI)科的所有工作流程,以确定流程改进(PI)是否能够改善关键绩效指标(KPI)。
研究者所在的 MRI 成像部门的 KPI 指标包括每日住院患者积压量、门诊检查的按时完成率、检查量、儿科麻醉病例的预约积压量以及相对于检查时间分配的扫描时间。在 2011 年 4 月的 3 周期间,MRI 成像部门的关键成员(包括技师、护士、调度员、医师和管理人员)跟踪了患者在部门内的所有流程,从预约到检查解读。小组对数据进行分析,以确定 PI 可以在哪些方面改进 KPI。随后对 MRI 工作流程进行了更改,并使用 Mann-Whitney 和 Fisher 确切检验比较了更改前后(2011 年 1 月 1 日至 4 月 30 日和 2011 年 8 月 1 日至 12 月 31 日)的 KPI。
PI 期间进行的数据分析导致 MRI 部门的日常工作流程发生了多项变化。此外,在 MRI 工作人员内部建立了新的团队合作和授权意识。在重新设计项目之后,所有测量的 KPI 均显示出统计学上的显著变化。
科室内的 PI 努力可以显著影响 MRI 成像部门的 KPI 指标,使流程更加以患者为中心。此外,该流程无需额外的设备或人员即可实现显著的增长。
