In the era of health information exchanges, there are trade-offs to consider when sharing a patient's medical record among all providers that a patient might choose. Exchange among in-network partners on the same electronic medical records (EMR) and other integrated information systems is trivial. The patient identifier is common, as are the releva...
Over the past 20 years, imaging informatics has been driven by the widespread adoption of radiology information and picture archiving and communication and speech recognition systems. These three clinical information systems are commonplace and are intuitive to most radiologists as they replicate familiar paper and film workflow. So what is next? T...

With increased workloads, geographically dispersed image acquisition and reading sites, and rapidly...
PURPOSE
The Joint Commission has set communication of critical test results as a National Patient Safety goal. They have defined critical test results as findings that warrant rapid communication coming from either a routine or critical test. In an inpatient setting where teams of physicians care for patients the ordering physician placing the radi...
PURPOSE
Information regarding productivity, performance, and quality metrics is now available through existing radiology infrastructures. This information is often scattered across multiple applications/platforms, with no means for easy extraction of key metrics (e.g., report turnaround time) that can power departmental analysis and appropriate cha...
CONCLUSION
The ideas of solitary compilation and categorization of studies to build topic encompassing teaching files is replaced with a communal effort and tools for discovery. In so doing it removes the 4 barriers of traditional teach file compilation.
BACKGROUND
Traditional teaching file systems present 4 barriers to contribution of the radiolo...
Routine clinical information systems now have the ability to gather large amounts of data that surgical managers can access to create a seamless and proactive approach to streamlining operations and minimizing delays. The challenge lies in aggregating and displaying these data in an easily accessible format that provides useful, timely information...
With advances in digital imaging throughout the 1990s and the rapid adoption of Picture Archiving and Communication Systems (PACS) in the last decade, standards for information exchange have become crucial to effective communication, both within the radiology department and with the larger enterprise and outside institutions and agencies. The origi...
The goal of all radiology information technology (IT) support organizations is excellent customer service through the availability of critical clinical information services, such as picture archiving communication systems and radiology information systems. Despite these goals, IT support personnel often act like firefighters, reacting to each probl...
PURPOSE
A PACS-integrated tool was developed to provide residents with feedback on preliminary reports and was evaluated in a large residency training program, where a portion of resident after-hours call experience is performed without in-house attending supervision and final reads are issued the next day.
METHOD AND MATERIALS
The ResReview syste...
PURPOSE
Many organizations struggle with determining appropriate staffing requirements for new or existing Picture Archiving and Communication Systems (PACS). Factors such as uptime requirements, support coverage and geographic distribution can all affect the level of staffing required for proper delivery of support. Striking an appropriate balance...
PURPOSE
Efforts to reduce time elapsed between imaging acquisition and dictation of results are challenged in an institutional setting by lapses in communication between technologists, radiologists, and business/processing staff. Imaging studies sometimes “hang” in the system, stalled by confusion over which action is required next. Although accoun...
PURPOSE
Our goal was to facilitate dynamic querying of the imaging report repository as an essential element in the implementation of several quality initiatives in radiology. As in most departments, the current RIS was designed to be queried at the application level but not at the interface level. By building a Web service-based report repository...
PACSPulse, an open-source tool, was developed to identify and analyze the performance bottlenecks of picture archiving and communication systems (PACS). PACSPulse provides a graphical Web interface for straightforward analysis of PACS performance on the basis of data acquired by tracking usage by network, server, workstation, type of traffic, and t...
Radiology departments are besieged with a multitude of information systems, each needing significant technical support. Information systems include the dictation system, the radiology information system (RIS), the picture archiving and communication systems (PACS), and every workstation and acquisition modality along with any dedicated system such...
PURPOSE/AIM
A Web-based forms engine that is clinically integrated provides a fast environment to collect data and track processes for quality projects. RIS and PACS often do not collect the right data or are slow to respond to change requests. We present a freely available, secured forms engine to augment a RIS and provide flexible data collection...

... In that case, it may somehow lead to tampering and interference by the patient or healthcare person mishandling [31]. Because of the above drawbacks, the Image Sharing Network (ISN) [32] comes into the limelight where Picture Archiving and Communication Systems (PACS) are implemented for image storing and sharing through centralized-based architecture. However, it has some concerns while being accessed by third parties or stakeholders. ...

... These inefficiencies lead to workflow inconsistencies and hinder radiologists' productivity. Furthermore, the complex operating logic in RIS interfaces results in intricate function logic, posing challenges for both experienced professionals and trainees [7,8]. The steep learning curve associated with understanding operational procedures and system component logic underscores the need for optimizing HCI in RIS to enhance user experience and efficiency. ...
... New electronic tools make the recorded issues easy to aggregate or audit and prevent frequently misplaced or lost reports entirely [5,6]. A web-based issue-reporting tool can help bridge the quality assessment (QA) process in modern radiology [6] notably in the gap between paper and fully interfaced QA software available directly in PACS that provides a system for reporting errors with minimal supporting staff effort and significantly less time investment by radiologists in [6][7][8]. Lowering the barriers for radiologists' access to QA problem reporting can dramatically increase the submission of QA issues [9]. This automated feedback can provide a vital link in improving diagnostic accuracy and technologists' performance in an environment of increasing workloads. ...
