The Role of Twitter in Radiology Medical Education and Research: A Review of Current Practices and Drawbacks.

The trends in society have provided favourable conditions for the rapid growth of radiology on social media, specifically there has been an expanding presence on Twitter. Currently, simple searches on Twitter yield a plethora of radiology education resources, that may be suited for medical students, residents or practicing radiologists. Educators have many tools at their disposal to deliver effective teaching. Over time, strategies such as including images and scrollable stacks often are more successful at gaining popularity or clicks online. Journals and authors can use Twitter to promote their new scientific work and potentially reach audiences they couldn't have prior. Attendees at conferences can get involved in the conversation by tweeting about the meeting and engaging with other attendees with mutual interests. Interested medical students, residents and even practicing radiologists can use Twitter as a means of networking and connecting with other scholars all around the globe. Within its glory, Twitter does carry some drawbacks including privacy concerns, equality, and risk of misinformation. Above all, the future of Twitter is bright and promising for all who are currently on it and plan to use it for their education, research, or professional advancement.

Barriers to Screening At-risk Populations in Canada.

Cancer screening is invaluable for early detection of disease, including for breast and lung cancer. Through early detection, cancer treatment can be commenced prior to the development of advanced stage disease, significantly reducing morbidity and mortality. However, eligible patients may face barriers when accessing screening services, and some groups may be more disproportionately affected than others. This review aims to describe some of the most prominent barriers that at-risk populations may face when accessing image-based cancer screening services in Canada. Characterizing these barriers would be helpful in determining the best strategies to increase uptake to these screening services and, consequently, improve health equity.

Renal Colic Imaging: Myths, Recent Trends, and Controversies.

There has been a substantial increase in the utilization of imaging, particularly of multi-detector computed tomography (MDCT), for the evaluation of patients with suspected urolithiasis over the past 2 decades. While the diagnostic accuracy of computed tomography (CT) for urolithiasis is excellent, it has also resulted in substantial medical expenditures and increased ionizing radiation exposure. This is especially concerning in patients with known nephrolithiasis and in younger patients. This pictorial review will focus on recent trends and controversies in imaging of patients with suspected urolithiasis, including the current roles of ultrasound (US), MDCT, and magnetic resonance imaging, the estimated radiation dose from MDCT and dose reduction strategies, as well as imaging of suspected renal colic in pregnant patients. The current epidemiological, clinical, and practice management literature will be appraised.

Characteristics and outcomes of an international cohort of 600 000 hospitalized patients with COVID-19.

BACKGROUND: We describe demographic features, treatments and clinical outcomes in the International Severe Acute Respiratory and emerging Infection Consortium (ISARIC) COVID-19 cohort, one of the world's largest international, standardized data sets concerning hospitalized patients. METHODS: The data set analysed includes COVID-19 patients hospitalized between January 2020 and January 2022 in 52 countries. We investigated how symptoms on admission, co-morbidities, risk factors and treatments varied by age, sex and other characteristics. We used Cox regression models to investigate associations between demographics, symptoms, co-morbidities and other factors with risk of death, admission to an intensive care unit (ICU) and invasive mechanical ventilation (IMV). RESULTS: Data were available for 689 572 patients with laboratory-confirmed (91.1%) or clinically diagnosed (8.9%) SARS-CoV-2 infection from 52 countries. Age [adjusted hazard ratio per 10 years 1.49 (95% CI 1.48, 1.49)] and male sex [1.23 (1.21, 1.24)] were associated with a higher risk of death. Rates of admission to an ICU and use of IMV increased with age up to age 60 years then dropped. Symptoms, co-morbidities and treatments varied by age and had varied associations with clinical outcomes. The case-fatality ratio varied by country partly due to differences in the clinical characteristics of recruited patients and was on average 21.5%. CONCLUSIONS: Age was the strongest determinant of risk of death, with a ∼30-fold difference between the oldest and youngest groups; each of the co-morbidities included was associated with up to an almost 2-fold increase in risk. Smoking and obesity were also associated with a higher risk of death. The size of our international database and the standardized data collection method make this study a comprehensive international description of COVID-19 clinical features. Our findings may inform strategies that involve prioritization of patients hospitalized with COVID-19 who have a higher risk of death.

Exploring social movement concepts and actions in a knowledge uptake and sustainability context: A concept analysis.

Objectives: To share a concept analysis of social movement aimed at advancing its application to evidence uptake and sustainability in health-care. Methods: We applied Walker and Avant method to clarify the concept of social movement in the context of knowledge uptake and sustainability. Peer-reviewed and grey literature databases were systematically searched for relevant reports that described how social movement action led to evidence-based practice changes in health and community settings. Titles, abstracts and full texts were reviewed independently and in duplicate, resulting in 38 included articles. Results: Social movement action for knowledge uptake and sustainability can be defined as individuals, groups, or organizations that, as voluntary and intrinsically motivated change agents, mobilize around a common cause to improve outcomes through knowledge uptake and sustainability. The 10 defining attributes, three antecedents and three consequences that we identified are dynamic and interrelated, often mutually reinforcing each other to fortify various aspects of the social movement. Examples of defining attributes include an urgent need for action, collective action and collective identity. The concept analysis resulted in the development of the Social Movement Action Framework. Conclusions: Social movement action can provide a lens through which we view implementation science. Collective action and collective identity - concepts less frequently canvassed in implementation science literature - can lend insight into grassroots approaches to uptake and sustainability. Findings can also inform providers and change leaders on the practicalities of harnessing social movement action for real-world change initiatives. By mobilizing individuals, groups, or organizations through social movement approaches, they can engage as powered change agents and teams that impact the individual, organizational and health systems levels to facilitate knowledge uptake and sustainability.

Optimizing Nursing Practice through Integration of Best Practice Guidelines into Electronic Medical Records.

A commitment to best practice guidelines (BPGs) is crucial for ensuring the safety of patients. Recognizing the power of information technology, Humber River Hospital has integrated BPGs into the electronic medical record (EMR) infrastructure. The large-scale implementation institutes a uniform standard of care and ensures adherence to BPGs through a forcing function designed to require nurses to complete and document the necessary assessments. The initiative strengthens the audit process and provides the opportunity to identify long-term trends. The implications of the quality improvement initiative are discussed. Due to the widespread use of EMRs, the replication of this initiative is economically feasible in other healthcare settings.

Violence Prevention: Technology-Enabled Therapeutic Intervention.

BACKGROUND: Nurses are disproportionately prone to experience incidents of violent victimization. Despite the vast literature on violence in healthcare settings, few studies have identified effective violence prevention interventions. AIM: The aim of the study was to explore the experiences of nurses regarding the implementation of technology-based violence prevention interventions. METHODS: Qualitative data were collected through semi-structured focus groups and interviews with 11 nurses at Humber River Hospital. Interviews were audiotaped, transcribed and subjected to a content analysis to identify core themes from the data. RESULTS: Three themes were identified: reassurance of safety, an increase in proactive measures and limitations of technology. Nurses held positive perceptions of the impact of technology-based interventions on violent incidents. The interventions were regarded as effective for the detection of potentially violent patients as well as for providing assistance from security staff when a violent incident occurs or appears imminent. However, nurses also acknowledged that patient-related violence was "unavoidable" and that technology cannot fully prevent violence from occurring. CONCLUSION: The findings from this study support the replication of these interventions in other healthcare facilities. Engaging staff, patients and families in this unique digital and technology-enriched environment has been critical for the successful implementation of the violence prevention electronic flagging system. Patient and family education and communication were essential for addressing concerns related to "labelling."
