Texas Children's Hospital is a pediatric tertiary care facility in the Texas Medical Center with a large-scale, Digital Imaging and Communications in Medicine (DICOM)-compliant picture archival and communications system (PACS) installation. As our PACS has grown from an ultrasound niche PACS into a full-scale, multimodality operation, assuring continuity of clinical operations has become the number one task of the PACS staff. As new equipment is acquired and incorporated into the PACS, workflow processes, responsibilities, and job descriptions must be revised to accommodate filmless operations. Round-the-clock clinical operations must be supported with round-the-clock service, including three shifts, weekends, and holidays. To avoid unnecessary interruptions in clinical service, this requirement includes properly trained operators and users, as well as service personnel. Redundancy is a cornerstone in assuring continuity of clinical operations. This includes all PACS components such as acquisition, network interfaces, gateways, archive, and display. Where redundancy is not feasible, spare parts must be readily available. The need for redundancy also includes trained personnel. Procedures for contingency operations in the event of equipment failures must be devised, documented, and rehearsed. Contingency operations might be required in the event of scheduled as well as unscheduled service events, power outages, network outages, or interruption of the radiology information system (RIS) interface. Methods must be developed and implemented for reporting and documenting problems. We have a Trouble Call service that records a voice message and automatically pages the PACS Console Operator on duty. We also have developed a Maintenance Module on our RIS system where service calls are recorded by technologists and service actions are recorded and monitored by PACS support personnel. In a filmless environment, responsibility for the delivery of images to the radiologist and referring physician must be accepted by each imaging supervisor. Thus, each supervisor must initiate processes to verify correct patient and examination identification and the correct count and routing of images with each examination.
德克萨斯儿童医院是位于德克萨斯医疗中心的一家儿科三级医疗设施,安装了大规模、符合医学数字成像和通信(DICOM)标准的图像存档与通信系统(PACS)。随着我们的PACS从一个超声专用PACS发展成为一个全面的多模态系统,确保临床操作的连续性已成为PACS工作人员的首要任务。随着新设备的购置并纳入PACS,工作流程、职责和工作描述必须进行修订,以适应无胶片操作。全天候的临床操作必须得到全天候服务的支持,包括三班倒、周末和节假日。为避免临床服务出现不必要的中断,这一要求包括训练有素的操作员、用户以及服务人员。冗余是确保临床操作连续性的基石。这包括所有PACS组件,如采集、网络接口、网关、存档和显示。在无法实现冗余的情况下,必须随时备有备件。冗余的需求还包括训练有素的人员。必须制定、记录并演练设备故障时的应急操作程序。在计划内和计划外的服务事件、停电、网络中断或放射学信息系统(RIS)接口中断的情况下,可能都需要进行应急操作。必须制定并实施报告和记录问题的方法。我们有一个故障呼叫服务,它会记录语音信息并自动呼叫值班的PACS控制台操作员。我们还在RIS系统上开发了一个维护模块,技术人员可以在该模块上记录服务呼叫,PACS支持人员可以记录并监控服务行动。在无胶片环境中,每个影像主管必须承担将图像传送给放射科医生和转诊医生的责任。因此,每个主管必须启动相关流程,以核实每个检查中患者和检查标识的正确性以及图像的正确数量和传送路径。
