Assessing information sources to elucidate diagnostic process errors in radiologic imaging - a human factors framework

Infection prevention and control in the medical imaging environment: a scoping review

Infection prevention and control (IPC) practices are key to preventing and controlling the spread of pathogens in medical imaging departments (MIDs). The objective of this scoping review was to synthesise information about current research in MID regarding IPC and to use the Systems Engineering Initiative for Patient Safety (SEIPS) model to identify the work system factors ('persons', 'organisation', 'tools and technology', 'tasks' and 'environment') influencing the practice of IPC, in order to better understand challenges and facilitators that affect IPC in MID. Predefined search terms and medical subject headings relating to IPC in the medical imaging setting were used to search 3 databases. A total of 46 publications met the inclusion criteria, which combined, encompassed all five SEIPS domains influencing IPC. The literature supports the interrelated nature of the five SEIPS domains, and influence to one another. Hand hygiene was a major focus of publications. Mechanisms of infection in contrast-enhanced computed tomography were most reported, with human error, lack of education, and issues associated with devices and processes mechanisms found to influence IPC breaches. A systems approach, such as the SEIPS model, is useful for understanding barriers and hence opportunities for improvement of IPC in the medical imaging setting. Future studies should address individuals' decision-making processes in the medical imaging setting, and a greater focus should be placed into the procedural steps, education and tools used for contrast media administration. CRITICAL RELEVANCE STATEMENT: A systems approach, such as the Systems Engineering Initiative for Patient Safety model, is useful for understanding barriers and hence opportunities for improvement of IPC in the medical imaging setting. KEY POINTS: 1. IPC in the medical imaging setting would benefit from a systems approach. 2. The role of education and monitoring of IPC compliance requires further research. 3. Geographical location is a key variable in IPC research in medical imaging.

Workflow Applications of Artificial Intelligence in Radiology and an Overview of Available Tools

In the past decade, there has been tremendous interest in applying artificial intelligence (AI) to improve the field of radiology. Currently, numerous AI applications are in development, with potential benefits spanning all steps of the imaging chain from test ordering to report communication. AI has been proposed as a means to optimize patient scheduling, improve worklist management, enhance image acquisition, and help radiologists interpret diagnostic studies. Although the potential for AI in radiology appears almost endless, the field is still in the early stages, with many uses still theoretical, in development, or limited to single institutions. Moreover, although the current use of AI in radiology has emphasized its clinical applications, some of which are in the distant future, it is increasingly clear that AI algorithms could also be used in the more immediate future for a variety of noninterpretive and quality improvement uses. Such uses include the integration of AI into electronic health record systems to reduce unwarranted variation in radiologists' follow-up recommendations and to improve other dimensions of radiology report quality. In the end, the potential of AI in radiology must be balanced with acknowledgment of its current limitations regarding generalizability and data privacy.

Integrity of clinical information in radiology reports documenting pulmonary nodules

OBJECTIVE

Quantify the integrity, measured as completeness and concordance with a thoracic radiologist, of documenting pulmonary nodule characteristics in CT reports and assess impact on making follow-up recommendations.

MATERIALS AND METHODS

This Institutional Review Board-approved, retrospective cohort study was performed at an academic medical center. Natural language processing was performed on radiology reports of CT scans of chest, abdomen, or spine completed in 2016 to assess presence of pulmonary nodules, excluding patients with lung cancer, of which 300 reports were randomly sampled to form the study cohort. Documentation of nodule characteristics were manually extracted from reports by 2 authors with 20% overlap. CT images corresponding to 60 randomly selected reports were further reviewed by a thoracic radiologist to record nodule characteristics. Documentation completeness for all characteristics were reported in percentage and compared using χ2 analysis. Concordance with a thoracic radiologist was reported as percentage agreement; impact on making follow-up recommendations was assessed using kappa.

RESULTS

Documentation completeness for pulmonary nodule characteristics differed across variables (range = 2%-90%, P < .001). Concordance with a thoracic radiologist was 75% for documenting nodule laterality and 29% for size. Follow-up recommendations were in agreement in 67% and 49% of reports when there was lack of completeness and concordance in documenting nodule size, respectively.

DISCUSSION

Essential pulmonary nodule characteristics were under-reported, potentially impacting recommendations for pulmonary nodule follow-up.

CONCLUSION

Lack of documentation of pulmonary nodule characteristics in radiology reports is common, with potential for compromising patient care and clinical decision support tools.

Building an Ambulatory Safety Program at an Academic Health System

BACKGROUND

Patient safety has traditionally focused on the inpatient setting; however, there is an increased awareness of ambulatory safety risk. However, successful strategies and programs to mitigate risk in the ambulatory setting are lacking.

PROGRAM

In 2012, we started building a multidisciplinary ambulatory safety program at an academic health system. Our team was composed of clinical, administrative, and patient safety membership. Based on organizational needs, our program initially focused on the following: (1) safety reporting, (2) safety culture measurement, (3) medication safety, and (4) test result management.

WHAT WE DID

We were able to develop initiatives around safety reporting, safety culture survey administration, and medication safety and begin to work on test result management. Internal metrics were developed to measure performance and to drive improvement.

SAFETY REPORTING

When evaluating our ambulatory safety reports, we discovered that less than one-third of staff filing safety reports requested feedback. From 2013 to 2018, we tested various strategies to increase the rates of feedback to staff and ultimately found that a decentralized process that was supported by the ambulatory safety program could achieve rates of feedback of 90%.

SAFETY CULTURE MEASUREMENT

We administered the Agency for Healthcare Research and Quality Medical Office Survey in 2012, 2014, and 2016, achieving a more than 70% response rate across 70 unique ambulatory areas. Data from these surveys were shared with senior hospital leadership, local departmental directors, and managers and ultimately with frontline staff focusing on two key survey areas: communication openness and communication about error.

MEDICATION SAFETY

From 2012 to 2014, our rates of ambulatory medication reconciliation increased to more than 90% in both primary care and specialty practices in our homegrown electronic medical record system. From 2015 to 2016, rates of ambulatory medication reconciliation in our new vendor-based electronic medical record were 73% as of August 2017.

CONCLUSIONS

We were able to build an infrastructure to focus and support ambulatory safety efforts on safety reporting, safety culture change, and medication reconciliation with a team dedicated to ambulatory-focused safety risks and encountered many challenges along the way. Currently, we are expanding our program to concentrate on test result follow-up to prevent missed and delayed diagnosis and medication error reduction.

Antimicrobial stewardship by Australian community pharmacists: Uptake, collaboration, challenges, and needs

OBJECTIVE

To assess community pharmacists' (CPs') awareness and uptake of evidence-based antimicrobial stewardship (AMS) strategies, attitudes toward collaboration with general practitioners (GPs), and needs to improve AMS practices.

METHODS

A nationwide survey of randomly sampled community pharmacies across Australia was conducted in April-October 2019.

RESULTS

The response rate of CPs was 30.7% (613 of 2000) and 592 participating CPs (96.5%) described the key barriers to and facilitators of improving AMS. CPs (447 of 613, 72.9%) were familiar with AMS but felt that they would require training (468 of 612, 76.5%) and access to AMS practice guidelines (566 of 605, 93.6%). Respondents perceived that AMS programs could reduce the inappropriate use of antimicrobials (409 of 612, 66.8%) and the costs of treating infection (508 of 612, 83.0%). CPs often counseled patients (591 of 609, 97.0%) and reviewed drug interactions or allergies (569 of 607, 93.8%) before dispensing antimicrobials. Respondents less often used the national Therapeutic Guidelines: Antibiotic (274 of 602, 45.5%) or assessed guideline-compliance of prescribed antimicrobials (231 of 609, 37.9%). CPs were less likely to communicate with GPs (254 of 609, 41.8%) when an antimicrobial prescription was believed to be suboptimal and perceived that GPs are not receptive to their intervention regarding the antimicrobial choice (500 of 606, 82.6%) and dosage (416 of 606, 68.6%). Point-of-care tests (114 of 596, 19.1%) and patient information leaflets (149 of 608, 24.5%) were used uncommonly. Most respondents supported policies that could foster GP-pharmacist collaboration (560 of 606, 92.4%), limit accessibility of selected antimicrobials (420 of 604, 74.4%), and reduce repeat-dispensing of antimicrobial prescriptions (448 of 604, 74.2%). CPs faced interpersonal, interactional, structural, and resource-level barriers to collaborate with GPs for practicing AMS.

CONCLUSIONS

CPs are aware of the importance of sensible use of antimicrobials but have had limited training and resources to conduct AMS activities. Improving GPs' receptiveness and system structures for increased GP-CP collaboration seem to be a priority to accelerate CP-led AMS implementation. Further study is required to understand the views of stakeholders about the feasibility of implementing evidence-based GP-CP collaborative AMS approaches.

Adapting a System-Theoretic Hazard Analysis Method for the Analysis of an eHealth Interoperability Conformance Profile

Interoperability between heterogenous (health) IT systems relies on standards, which are communicated to system vendors in the form of so-called conformance profiles. Clinical information systems are often subjected to mandatory conformance testing and certification prior to being admitted into the health information exchange (HIE). The requirements specified in conformance profiles are therefore instrumental for ensuring the correctness and safety of the emerging HIE network. How can we ensure the quality and safety of conformance requirements themselves? We have adapted a system-theoretic hazard analysis method (STPA) for this purpose and applied it to an industrial case study in British Columbia, the Clinical Data eXchange (CDX) system. Our results indicate that the method is effective in detecting missing and erroneous constraints.

Human Factors and Sociotechnical Issues

OBJECTIVE

To summarize significant research contributions on human factors (HF) and organizational issues in medical informatics published in 2018.

METHODS

An extensive search using PubMed/Medline and Web of Science^® was conducted to identify the scientific contributions published in 2018 that address human factors and organizational issues in medical informatics. The selection process comprised three steps: (i) 15 candidate best papers were first selected by the two section editors, (ii) external reviewers from internationally renowned research teams reviewed each candidate best paper, and (iii) the final selection of four best papers was conducted by the editorial board of the Yearbook.

RESULTS

The four selected best papers are excellent contributions to the HF literature: they show the added value of HF studies by providing nice illustrated and rigorous interventions.

CONCLUSION

HF interventions are known to have great potential to contribute to efficient HIT design, but the interventions still face challenges in successfully demonstrating their value to the main stakeholders of the healthcare domain. There is a need to strengthen the demand for high-quality HF studies by increasing awareness among powerful stakeholders of the value of high-quality HF studies.
