Analysis of critical report notification from musculoskeletal radiology in a tertiary academic medical institution with a regional trauma center.

PURPOSE: We aimed to analyze the prevalence, causes, and clinical settings of 4-year critical radiologic reports (CRRs) notified from the musculoskeletal section of the radiology department. Then, we investigated the communication outcomes. METHODS: This study was approved by our institutional review board. We retrospectively included 175 musculoskeletal CRRs from our database between January 2017 and December 2020. The CRRs were analyzed by two musculoskeletal radiologists, who categorized the CRRs by clinical setting (emergency department(ED) patient, outpatient, and inpatient), body part, type of image modality, reason for CRR, incidental lesion, and clinical outcome. The clinical outcome was retrieved from the electronic medical records. RESULTS: The 175 musculoskeletal CRRs accounted for 5.4% of the CRRs (n = 3217) available in the study period. Most CRRs (94.9%, 166/175) corresponded to the musculoskeletal system, while the remaining ones (5.1%, 9/175) corresponded to the non-musculoskeletal system. In addition, the spine, extremities, and thoracic cage accounted for 52.6%, 40.6%, and 1.7% of the musculoskeletal CRRs, respectively. Moreover, most patients presented to the ED (50.3%, 88/175), followed by inpatients (30.9%, 54/175), and outpatients (18.9%, 33/175). The CRR reasons included missed fracture (54.3%), suspected malignancy (16%), clinical emergency (10.3%), unexpected infection/inflammation (11.4%), and others (8%). Furthermore, 11 (6.3%) incidental lesions were not related to the primary imaging purpose. Referring clinicians actively acknowledged 80% of the CRRs. The loss to follow-up action was the highest in the ED patients (35.2%, 31/88; p < 0.001), being significantly higher than that in outpatients (6.1%, 2/33) and inpatients (3.7%, 2/54). CONCLUSION: Missed fractures were the most common cause of musculoskeletal CRRs. ED showed prevalence in musculoskeletal CRRs and reflected the highest loss to follow-up action. ED physicians should pay more attention to CRRs to enhance patient care.

In this article, the updated status of interventional radiology (IR) in China is reported and compared vs that a decade ago based on a poll carried out in 2017 in Jiangsu Province, where the economy and overall health level are among the best of the 31 provinces in China. All 98 polled centers responded, and 56 IR departments (57%) had become independent departments separate from the radiology department; 74 (76%) had inpatient wards. In 2017, there were 538 interventional radiologists performing IR procedures in Jiangsu Province, with a total of 69,277 procedures performed, with interventional oncologic procedures accounting for the largest proportion (58%).

Migrating to the Modern PACS: Challenges and Opportunities.

With progressive advancements in picture archiving and communication system (PACS) technology, radiology practices frequently look toward system upgrades and replacements to further improve efficiency and capabilities. The transition between PACS has the potential to derail the operations of a radiology department. Careful planning and attention to detail from radiology informatics leaders are imperative to ensure a smooth transition. This article is a review of the architecture of a modern PACS, highlighting areas of recent innovation. Key considerations for planning a PACS migration and important issues to consider in data migration, change management, and business continuity are discussed. Beyond the technical aspects of a PACS migration, the human factors to consider when managing the cultural change that accompanies a new informatics tool and the keys to success when managing technical failures are explored.

2017 ACR Annual Meeting Open-Microphone Session: Navigating the Landscape of Changing Practice Models: Private Practice, Corporate Radiology, and Enterprise Systems.

Many practice groups are considering adopting new practice models, primarily to secure their practices by adapting to new payment models, government compliance and regulation, and increasing IT and infrastructure costs. As we move toward value-based care and capitation, the value equation (value = quality/cost) will lead us to also compete on cost to improve value. No matter what payment models ultimately dominate, we need to be prepared to lead in a value-based care environment. Measures of value will either be defined by radiologists or imposed by outside entities. It is critical to our continued success that practices and practice leaders continue to fully and strongly support the ACR to avoid the possibility of a decline in membership that may accompany a lack of practice engagement. Consolidation appears inevitable, but with the help of the ACR, radiologists should have a vibrant future if investments are made now in determining appropriate radiology-specific value measures that are meaningful in consolidated health care environments.

Association Between Radiologic Incidental Findings and Resource Utilization in Patients Admitted With Chest Pain in an Urban Medical Center.

BACKGROUND: Increasing use of testing among hospitalized patients has resulted in an increase in radiologic incidental findings (IFs), which challenge the provision of high-value care in the hospital setting. OBJECTIVE: To understand impact of radiologic incidental findings on resource utilization in patients hospitalized with chest pain. DESIGN: Retrospective observational cross sectional study. SETTING: Academic medical center. PARTICIPANTS: Adult patients hospitalized with principal diagnosis of chest pain. MEASUREMENTS: Demographic, imaging, and length of stay (LOS) data were abstracted from the medical charts. We used multiple logistic regression to evaluate factors associated with radiologic IFs and negative binomial regression to evaluate the association between radiologic IFs and LOS. RESULTS: 1811 consecutive admissions with chest pain were analyzed retrospectively over a period of 24 months; 376 patients were included in the study after exclusion criteria were applied and readmissions removed. Of these, 197 patients (52%) had 364 new radiologic IFs on imaging; most IFs were of minor (50%) or moderate clinical significance (42%), with only 7% of major significance. Odds of finding radiologic IFs increased with age (adjusted odds ratio, 1.04; 95% confidence interval [CI], 1.01-1.06) and was associated with a 26% increase in LOS (adjusted incidence rate ratio, 1.26; 95% CI, 1.07-1.49). CONCLUSION: Radiologic IFs were very common among patients hospitalized with chest pain of suspected cardiac origin and independently associated with an increase in the LOS. Interventions to address radiologic IFs may reduce LOS and, thereby, support high-value care. Journal of Hospital Medicine 2017;12:323-328.

Dose Monitoring in Radiology Departments: Status Quo and Future Perspectives.

UNLABELLED: The number of computed tomography examinations has continuously increased over the last decades and accounts for a major part of the collective radiation dose from medical investigations. For purposes of quality assurance in modern radiology a systematic monitoring and analysis of dose related data from radiological examinations is mandatory. Various ways of collecting dose data are available today, for example the Digital Imaging and Communication in Medicine - Structured Report (DICOM-SR), optical character recognition and DICOM-modality performed procedure steps (MPPS). The DICOM-SR is part of the DICOM-standard and provides the DICOM-Radiation Dose Structured Report, which is an easily applicable and comprehensive solution to collect radiation dose parameters. This standard simplifies the process of data collection and enables comprehensive dose monitoring. Various commercial dose monitoring software devices with varying characteristics are available today. In this article, we discuss legal obligations, various ways to monitor dose data, current dose monitoring software solutions and future perspectives in regard to the EU Council Directive 2013/59/EURATOM. KEY POINTS: • Automated, systematic dose monitoring is an important element in quality assurance of radiology departments. • DICOM-RDSR-capable CT scanners facilitate the monitoring of dose data. • A variety of commercial and non-commercial dose monitoring software tools are available today. • Successful dose monitoring requires comprehensive infrastructure for monitoring, analysing and optimizing radiation exposure.

Daily, weekly, and monthly data were analyzed to statistically determine the current and future demands for the isotope Tc. This analysis was performed by collecting and analyzing data on MOH consumption of Tc for different diagnostic applications. The overall results indicate a partial decrease of 1.012% in the overall total demand for Tc up to the year 2018 for the state of Kuwait.

Big Data and the Future of Radiology Informatics.

Rapid growth in the amount of data that is electronically recorded as part of routine clinical operations has generated great interest in the use of Big Data methodologies to address clinical and research questions. These methods can efficiently analyze and deliver insights from high-volume, high-variety, and high-growth rate datasets generated across the continuum of care, thereby forgoing the time, cost, and effort of more focused and controlled hypothesis-driven research. By virtue of an existing robust information technology infrastructure and years of archived digital data, radiology departments are particularly well positioned to take advantage of emerging Big Data techniques. In this review, we describe four areas in which Big Data is poised to have an immediate impact on radiology practice, research, and operations. In addition, we provide an overview of the Big Data adoption cycle and describe how academic radiology departments can promote Big Data development.

The effects of changes in utilization and technological advancements of cross-sectional imaging on radiologist workload.

RATIONALE AND OBJECTIVES: To examine the effect of changes in utilization and advances in cross-sectional imaging on radiologists' workload. MATERIALS AND METHODS: All computed tomography (CT) and magnetic resonance imaging (MRI) examinations performed at a single institution between 1999 and 2010 were identified and associated with the total number of images for each examination. Annual trends in institutional numbers of interpreted examinations and images were translated to changes in daily workload for the individual radiologist by normalizing to the number of dedicated daily CT and MRI work assignments, assuming a 255-day/8-hour work day schedule. Temporal changes in institutional and individual workload were assessed by Sen's slope analysis (Q = median slope) and Mann-Kendall test (Z = Z statistic). RESULTS: From 1999 to 2010, a total of 1,517,149 cross-sectional imaging studies (CT = 994,471; MRI = 522,678) comprising 539,210,581 images (CT = 339,830,947; MRI = 199,379,634) were evaluated at our institution. Total annual cross-sectional studies steadily increased from 84,409 in 1999 to 147,336 in 2010, representing a twofold increase in workload (Q = 6465/year, Z = 4.2, P < .0001). Concomitantly, the number of annual departmental cross-sectional images interpreted increased from 9,294,140 in 1990 to 94,271,551 in 2010, representing a 10-fold increase (Q = 8707876/year, Z = 4.5, P < .0001). Adjusting for staffing changes, the number of images requiring interpretation per minute of every workday per staff radiologist increased from 2.9 in 1999 to 16.1 in 2010 (Q = 1.7/year, Z = 4.3, P < .0001). CONCLUSIONS: Imaging volumes have grown at a disproportionate rate to imaging utilization increases at our institution. The average radiologist interpreting CT or MRI examinations must now interpret one image every 3-4 seconds in an 8-hour workday to meet workload demands.

Rethinking radiology informatics.

OBJECTIVE: Informatics innovations of the past 30 years have improved radiology quality and efficiency immensely. Radiologists are groundbreaking leaders in clinical information technology (IT), and often radiologists and imaging informaticists created, specified, and implemented these technologies, while also carrying the ongoing burdens of training, maintenance, support, and operation of these IT solutions. Being pioneers of clinical IT had advantages of local radiology control and radiology-centric products and services. As health care businesses become more clinically IT savvy, however, they are standardizing IT products and procedures across the enterprise, resulting in the loss of radiologists' local control and flexibility. Although this inevitable consequence may provide new opportunities in the long run, several questions arise. CONCLUSION: What will happen to the informatics expertise within the radiology domain? Will radiology's current and future concerns be heard and their needs addressed? What should radiologists do to understand, obtain, and use informatics products to maximize efficiency and provide the most value and quality for patients and the greater health care community? This article will propose some insights and considerations as we rethink radiology informatics.

Analysis of the last decade of weekend out-of-hours CT imaging: how have things changed?

CT has become an invaluable diagnostic tool. The clinical applications and technological capacity of CT has continued to increase. There is an increasing demand for radiology services including during weekend on-call hours. The objective of this study was to assess the trend in weekend CT imaging requests over a ten-year period form 2001-2010. Electronic data was retrieved from the hospital Radiology Inpatient System. In total 8530 CT scans were performed during weekend on-call hours. Over the decade weekend imaging grew from 466 to 1448 (210.7%) CT examinations. CT brain imaging accounted for 3944 of the total 8530(46%) and this was a 126% increase. A ten-fold, eight-fold and three-fold increase occurred in adult CT thorax, CT pelvis and CT abdominal imaging respectively. These results demonstrate rising demand on radiology services and need to plan for continued future growth. Radiology and emergency departments need to prepare and develop pathways to deal with this projected growth.

Implementation of 24/7 radiology services in an academic medical centre level 1 trauma centre: impact on trauma resuscitation unit length of stay and economic benefit analysis.

STUDY OBJECTIVE: To evaluate the impact of 24/7 radiology services on trauma resuscitation unit (TRU) length of stay (LOS) for patients with minor trauma and to analyse the economic benefits of such an impact from trauma centre perspective. METHODS: The study was HIPAA compliant and had IRB approval. Data were extracted from hospital and radiology information systems. Inclusion criteria specified patients: (a) with minor trauma (i.e., Injury Severity Score<16 and Maximum Abbreviated Injury Scale<4); (b) cross-sectional imaging performed between 12 and 7AM; and (c) admission during 2006 (before 24/7 coverage; comparison group 1) or 2007 (24/7 coverage). Mean, median, standard deviation, and variance for the groups were determined. The theoretical economic benefit achieved with 24/7 radiology coverage was estimated from decreases in TRU LOS for each patient. RESULTS: Totals of 1087 and 1323 patients for 2006 and 2007, respectively, met our selection criteria. Mean TRU LOS decreased from 11.19 to 8.25 h (26%; P<0.001). The median decreased from 10.8 to 7.2 h (33%; P<0.001). The (Q3-Q1) indicator, used as a proxy for variance and spread, decreased from 7.36 to 5.76 h. Theoretical economic benefits from 24/7 radiology coverage were achieved by the product of TRU bed fixed costs with mean decrease in TRU LOS for the calendar year 2007, which equaled $340,069. CONCLUSION: The economic benefits of 24/7 radiology services are related to LOS, which can be shortened by limiting patient discharge delays resulting from report unavailability. This can be a cost-saving replacement for conventional radiology practice when the trauma centre makes appropriate use of vacant TRU beds to realise its opportunity cost.

User acceptance of a picture archiving and communication system (PACS) in a Saudi Arabian hospital radiology department.

BACKGROUND: Compared with the increasingly widespread use of picture archiving and communication systems (PACSs), knowledge concerning users' acceptance of such systems is limited. Knowledge of acceptance is needed given the large (and growing) financial investment associated with the implementation of PACSs, and because the level of user acceptance influences the degree to which the benefits of the systems for healthcare can be realized. METHODS: A Technology Acceptance Model (TAM) was used to assess the level of acceptance of the host PACS by staff in the radiology department at King Abdulaziz Medical City (KAMC), Riyadh, Saudi Arabia. A questionnaire survey of 89 PACS users was employed to obtain data regarding user characteristics, perceived usefulness (PU) (6 items), perceived ease of use (PEU) (4 items), a change construct (4 items), and a behavior (acceptance) construct (9 items). Respondents graded each item in each construct using five-point likert scales. RESULTS: Surveyed users reported high levels of PU (4.33/5), PEU (4.15/5), change (4.26/5), and acceptance (3.86/5). The three constructs of PU, PEU, and change explained 41 % of the variation in PACS user acceptance. PU was the most important predictor, explaining 38 % of the variation on its own. The most important single item in the explanatory constructs was that users found PACS to have improved the quality of their work in providing better patient care. Technologists had lower acceptance ratings than did clinicians/radiologists, but no influence on acceptance level was found due to gender, age, or length of experience using the PACS. Although not directly measured, there appeared to be no cultural influence on either the level of acceptance or its determinants. CONCLUSIONS: User acceptance must be considered when an organization implements a PACS, in order to enhance its successful adoption. Health organizations should adopt a PACS that offers all required functions and which is likely to generate high PU on the part of its users, rather than a system that is easy to use. Training/familiarization programs should aim at establishing high levels of PU in all users, particularly technologists. Health organizations are advised to measure all the factors that influence the acceptance of a PACS by their staff, in order to optimize the productivity of the system and realize the potential benefits to the greatest extent possible.

Our path to a filmless future.

Film-based radiographs are still being used to teach in a conference format, which presents several viewing challenges amongst other problems. In the age of cloud computing, which enables the use of online server storage space, this information could be used more effectively if it were digitized. However, digitizing film-based radiographs and making them available for use in the cloud is not as easy as it seems. In order to address the issue of digitizing the film-based radiograph libraries in our radiology department, we looked at several options. The option that we chose was a consumer-grade scanner, and this decision was based on price, resolution, shades of gray, built-in transparency function, and its physical attributes. Our goal was to digitize the film-based radiograph teaching files so they could be stored in a digital file locker such as Google Picassa for organization and quick access later. These files would constantly be updated in a Google document by residents, and this document would be called the "Living Document" based on its continuous expandability. This method would allow even the smallest radiology department to benefit from the use of modern technology to gain access to valuable information stored in film-based radiographs and give every resident the opportunity to benefit from it.
