There is growing interest from multiple specialties, including internal medicine, to incorporate diagnostic point of care ultrasound (POCUS) into standard clinical care. However, few internists currently use POCUS. The objective of this study was to understand the current determinants of POCUS adoption at both the health system and clinician level at a U.S. academic medical center from the perspective of multi-level stakeholders. We performed semi-structured interviews of multi-level stakeholders including hospitalists, subspecialists, and hospital leaders at an academic medical center in the U.S. Questions regarding the determinants of POCUS adoption were asked of study participants. Using the framework method, team-based analysis of interview transcripts were guided by the contextual domains of the Practical Robust Implementation and Sustainability Model (PRISM). Thirty-one stakeholders with diverse roles in POCUS adoption were interviewed. Analysis of interviews revealed three overarching themes that stakeholders considered important to adoption by clinicians and health systems: clinical impact, efficiency and cost. Subthemes included two that were deemed essential to high-fidelity implementation: the development of credentialing policies and robust quality assurance processes. These findings identify potential determinants of system and clinician level adoption that may be leveraged to achieve high-fidelity implementation of POCUS applications that result in improved patient outcomes.

Despite inferior vena cava (IVC) filter practice spanning over 50 years, interventionalists face many controversies in proper utilization and management. This article reviews recent literature and offers opinions on filter practices. IVC filtration is most likely to benefit patients at high risk of iatrogenic pulmonary embolus during endovenous intervention. Filters should be used selectively in patients with acute trauma or who are undergoing bariatric surgery. Retrieval should be attempted for perforating filter and fractured filter fragments when imaging suggests feasibility and favorable risk-to-benefit ratio. Antibiotic prophylaxis should be considered when removing filters with confirmed gastrointestinal penetration. Anticoagulation solely because of filter presence is not recommended except in patients with active malignancy. Anticoagulation while filters remain in place may decrease long-term filter complications in these patients. Patients with a filter and symptomatic IVC occlusion should be offered filter removal and IVC reconstruction. Physicians implanting filters may maximize retrieval by maintaining physician-patient relationships and scheduling follow-up at time of placement. Annual follow-up allows continued evaluation for removal or replacement as appropriate. Advanced retrieval techniques increase retrieval rates but require caution. Certain cases may require referral to experienced centers with additional retrieval resources. The views expressed should help guide clinical practice, future innovation, and research.

RATIONALE AND OBJECTIVES: To assess the immediate impact of the COVID-19 pandemic on Diagnostic and Interventional Radiology education, and to propose measures to preserve and augment trainee education during future crises. MATERIALS AND METHODS: Diagnostic Radiology (DR) studies and Interventional Radiology (IR) procedures at a single tertiary-care teaching institution between 2015 and 2020 were reviewed. DR was divided by section: body, cardiothoracic, musculoskeletal (MSK), neuroradiology, nuclear medicine, pediatrics, and women's imaging. IR was divided by procedural types: arterial, venous, lymphatic, core, neuro, pediatrics, dialysis, cancer embolization or ablation, noncancer embolization, portal hypertension, and miscellaneous. Impact on didactic education was also assessed. ANOVA, t test, and multiple comparison correction were used for analysis. RESULTS: DR and IR caseloads decreased significantly in April 2020 compared to April of the prior 5 years (both p < 0.0001). Case volumes were reduced in body (49.2%, p < 0.01), MSK (54.2%, p < 0.05), neuro (39.3%, p < 0.05), and women's imaging (75.5%, p < 0.05) in DR, and in arterial (62.6%, p < 0.01), neuro IR (57.6%, p < 0.01) and core IR (42.6%, p < 0.05) in IR. IR trainee average caseload in April 2020 decreased 51.9% compared to April of the prior 5 years (p < 0.01). Utilization of online learning increased in April. Trainees saw significant increases in overall DR didactics (31.3%, p = 0.02) and no reduction in IR didactics, all online. Twelve major national and international DR and IR meetings were canceled or postponed between March and July. CONCLUSION: Decreases in caseload and widespread cancellation of conferences have had significant impact on DR/IR training during COVID-19 restrictions. Remote learning technologies with annotated case recording, boards-style case reviews, procedural simulation and narrated live cases as well as online lectures and virtual journal clubs increased during this time. Whether remote learning can mitigate lost opportunities from in-person interactions remains uncertain. Optimizing these strategies will be important for potential future restricted learning paradigms and can also be extrapolated to augment trainee education during unrestricted times.
