Clinical placement challenges associated with radiography education in a low-resource setting: A qualitative exploration of the Ethiopian landscape

IntroductionClinical placements (CP) are of paramount importance in the learning and the acquisition of key competencies in terms of knowledge, skill and professional attributes required for clinical radiography practice. This study explored the challenges faced by radiography students and educators in relation to clinical placement and training in Ethiopia.MethodsA qualitative approach using focus group discussion and interviews were used to explore the experiences of students and educators, respectively, pertaining to challenges encountered in relation to the clinical placement of students across four university affiliated hospitals. Data obtained was analysed using a structured three step framework and the coding approach employed in a thematic analysis.ResultsParticipants comprise of third- and fourth-year undergraduate radiography students (n = 14) and educators [academic faculty (n = 7) and clinical practice educators (n = 8)]. Four main themes were identified, which relate to deficiencies of an existing training curriculum and its implementation strategies, inadequate resource and infrastructure within the CP environments and absence of advanced training opportunities.ConclusionThis research showed that there are many and varied challenges encountered by both students and educators in relation to CP and training of radiography students in Ethiopia. These challenges could potentially affect the future performance of students/practitioners and/or the appropriate application of the core clinical radiography skills and competencies in the world of work.Implications for practiceClinical radiography training in resource-limited settings will require urgent attention and support with modern infrastructure including simulation to augment their clinical development to acceptable standards.     

Patient and Provider Perspectives of Telehealth and In-Person Interventional Radiology Clinic Visits

PurposeTo assess patient and provider satisfaction with interventional radiology (IR) outpatient telehealth and in-person clinic.Materials and MethodsThis institutional review board–approved study analyzed patient satisfaction with clinic via survey after an IR outpatient telehealth or in-person visit. A physician telehealth experience survey was completed by 8 IR physicians.ResultsDuring the initial survey period, 44 (83%) of 53 patients completed a survey via telephone compared with 37 (23%) of 158 patients who were offered an electronic survey during the second survey period. Of 81 respondents, 18 (22%) were in-person and 63 (78%) were via telehealth. Of the respondents, nearly all patients (97%) in the telehealth group reported satisfaction with their telehealth clinic visit, with similar rates of high patient satisfaction between in-person and telehealth visits (P = .51). Most patients (98%) in the telehealth group strongly agreed that their physician’s recommendations were clear in the telehealth visit and that their visit was private, similar to in-person visits (P = .13). A telehealth visit saved time for all patients (100%), with 78% reporting >1 hour of time-saving. All IR physicians (n = 8) reported greater efficiency with telehealth clinic than with in-person clinic and that follow-up patterns would change if telehealth was available. However, all providers (100%) found telephone visits less satisfying than in-person visits, with video visits being either equally satisfying (71%) or less satisfying (29%).ConclusionsPatient satisfaction with the in-person and telehealth outpatient IR clinic was high, with patients and providers reporting time-saving and greater efficiency with telehealth, suggesting that telehealth should remain an important component of outpatient IR clinic care.     

Developing a Comprehensive Resident-driven Research Training Pathway: A Chief Resident's Perspective

Wide variation exists in research training, experience, opportunities, and exposure across various radiology residency training programs, ranging from having a dedicated research track to no exposure to hypothesis driven projects. Studies conducted at different residency training programs with varied resources and National Institutes of Health funding have shown that resident-driven research initiatives and mentorship programs have the potential to improve research experience during residency training, engage more medical students in research, increase departmental peer-reviewed publications and increase peer-reviewed publications of early-career faculty physicians. In an attempt to standardize the research training during radiology residency, we propose a standardized resident-led program which institutions may adapt, as well as resources that the American Alliance of Academic Chief Residents in Radiology (A³CR²) might compile in collaboration with other national organizations to improve trainee's research experience during their radiology residency training.     

Results of an American College of Radiology-Society of Interventional Radiology Membership Survey on Exclusive Contracts and the Attitudes of Interventional Radiologists

PurposeTo assess the attitudes of interventional radiologists (IRs) and diagnostic radiologists (DRs) toward exclusive contracts and independently practicing IRs who may request privileges at a hospital where an exclusive contract exists with a different group of radiologists.Materials and MethodsA total of 22,400 survey instruments were distributed to 4,490 IRs and 17,910 DRs in the United States. Statistical evaluation included multivariate ordinal logistic regression analysis with calculation of the odds ratios and forest plots.ResultsCompleted surveys were received from 525 (11.69%) IRs and 401 (2.23%) DRs. Given the low response rate of DRs, data analysis was focused on IRs. Early-career IRs and those in outpatient practices had a more positive attitude toward independent IRs who requested admitting and/or procedural privileges. A supermajority of both IRs and DRs who responded to the survey agreed that the importance of IR to hospital and health system contracts will increase.ConclusionsThis survey identified many interrelated and complex variables that significantly affected the attitudes of IRs in various practice settings toward independent IRs requesting hospital admitting and/or procedural privileges. It will benefit independent IRs seeking admitting privileges to better understand some of the factors that impact the potential willingness of the radiology groups and other IRs with exclusive hospital contracts to work toward mutually beneficial practice paradigms, especially as more clinically oriented IRs complete their training in the new, integrated residency programs.     

Appendix to the Society of Interventional Radiology Consensus Guidelines for the Periprocedural Management of Thrombotic and Bleeding Risk in Patients Undergoing Percutaneous Image-Guided Interventions: Pediatric Considerations

PurposeTo provide guidance on the use of anticoagulant and antithrombotic agents in pediatric patients undergoing interventional radiology procedures.Materials and MethodsA multidisciplinary writing group conducted a comprehensive literature search to identify studies on the topic of interest. Recommendations were developed for procedural risk and medication dosage and withholding. A modified Delphi technique was used to achieve consensus agreement on the recommendations.ResultsA total of 24 studies, including systematic reviews and meta-analyses, randomized controlled trials, and prospective and retrospective cohort studies, were identified as relevant. The expert writing group agreed on procedural risk categorization, laboratory testing thresholds, and medication dosage and withholding recommendations specific to pediatric practice. They additionally described the nuances of anticoagulation in clinical conditions specific to pediatrics.ConclusionsThe Society of Interventional Radiology recommends following the guidance provided in the document when developing multidisciplinary management protocols for anticoagulation and antithrombotic treatment in pediatric patients undergoing interventional radiology procedures.     

Burnout among Interventional Radiologists

PurposeTo characterize burnout, as defined by high emotional exhaustion (EE) or depersonalization (DP), among interventional radiologists using a validated assessment tool.Materials and MethodsAn anonymous 34-question survey was distributed to interventional radiologists. The survey consisted of demographic and practice environment questions and the 22-item Maslach Burnout Inventory–Human Services Survey (MBI). Interventional radiologists with high scores on EE (≥ 27) or DP (≥ 10) MBI subscales were considered to have a manifestation of career burnout.ResultsBeginning on January 7, 2019, 339 surveys were completed over 31 days. Of respondents, 263 (77.6%) identified as male, 75 (22.1%) identified as female, and 1 (0.3%) identified as trans-male. The respondents were interventional radiology attending physicians (298; 87.9%), fellows (20; 5.9%), and residents (21; 6.2%) practicing at academic (136; 40.1%), private (145; 42.8%), and hybrid (58; 17.1%) centers. Respondents worked < 40 hours (15; 4.4%), 40–60 hours (225; 66.4%), 60–80 hours (81; 23.9%), and > 80 hours (18; 5.3%) per week. Mean MBI scores for EE, DP, and personal achievement were 30.0 ± 13.0, 10.6 ± 6.9, and 39.6 ± 6.6. Burnout was present in 244 (71.9%) participants. Identifying as female (odds ratio 2.4; P = .009) and working > 80 hours per week (odds ratio 7.0; P = .030) were significantly associated with burnout.ConclusionsBurnout is prevalent among interventional radiologists. Identifying as female and working > 80 hours per week were strongly associated with burnout.     

Computed tomography colonography: Radiographer independent preliminary clinical evaluation for intraluminal pathology

IntroductionWe evaluated the reporting competency of radiographers providing preliminary clinical evaluations (PCE) for intraluminal pathology of computed tomography colonography (CTC).MethodFollowing validation of a suitable tool, audit was undertaken to compare radiographer PCE against radiology reports. A database was designed to capture radiographer and radiologist report data. The radiographer's PCE of intraluminal pathology was given a score, the “pathology discrepancy and significance” (PDS) score based on the pathology present, any discrepancy between the PCE and the final report, and the significance of that discrepancy on the management of the patient. Agreement was assessed using percentage agreement and Kappa coefficient. Significant discrepancies between findings were compared against endoscopy and pathology reports.ResultsThere was agreement or insignificant discrepancy between the radiographer PCE and the radiology report for 1736 patients, representing 97.0% of cases. There was a significant discrepancy between findings in 2.8% of cases and a major discrepancy recorded for 0.2% of cases. There was a 98.4% agreement in the 229 cases where significant pathologies were present.ConclusionFrom a database of 1815 studies acquired over three years and representing work done in a clinical environment, this study indicates a potential for trained radiographers to provide a PCE of intraluminal pathology.     

Contemporary cardiovascular computed tomography (CCT) training: Serial surveys of the international CCT community by the Fellow and Resident Leaders of the Society of Cardiovascular Computed Tomography (SCCT) Committee (FiRST) and SCCT Future Leaders Program (FLP)

BackgroundAs cardiovascular computed tomography (CCT) practice evolves, the demand for specialists continues to increase. However, CCT training remains variable globally with limited contemporaneous data to understand this heterogeneity. We sought to understand the role of CCT globally and the training available to underpin its use.MethodsWe performed two consecutive surveys of cardiology and radiology physicians, two years apart, utilizing the Society of Cardiovascular Computed Tomography (SCCT) website, weblinks, social media platforms, and meeting handouts to maximize our response rate. We compared United States (US)-based vs. international responses to understand global similarities and differences in practice and training in the surveys.Results235 respondents (37% trainees and 63% educators/non-trainees) initiated the first survey with 174 (74%) completing the core survey, with 205 providing their work location (114 US and 91 international). Eighty-four percent (92/110) of educator respondents stated a need for increased training opportunities to meet growing demand. Dedicated training fellowships are heterogenous, with limited access to structural heart imaging training, despite structural scanning being performed within institutions. The lack of a standardized curriculum was identified as the main obstacle to effective CCT learning, particularly in the US, with web-based learning platforms being the most popular option for improving access to CCT training. 148 trainees initiated the second survey with 107 (72%) completing the core components (51% North America, 49% international). Only 68% said they would be able to meet their required CCT education needs via their training program. Obstacles in obtaining CCT training again included a lack of a developed curriculum (51%), a lack of dedicated training time (35%), and a lack of local faculty expertise (31%). There was regional variability in access to CCT training, and, in contrast to the first survey, most (89%) felt 1:1 live review of cases with trained/expert reader was most useful for improving CCT training alongside formal curriculum/live lectures (72%).ConclusionsThere is a need to expand dedicated CCT training globally to meet the demand for complex CCT practice. Access to CCT education (didactic and 1:1 case-based teaching from expert faculty), implementation of recently published global training curricula, and increased teaching resources (web-based) as an adjunct to existing experiential learning opportunities, are all deemed necessary to address current educational shortfalls.     

Management of patients with suspected or confirmed COVID-19, in the radiology department

ObjectivesFrom December 2019, a novel coronavirus disease named COVID-19 was reported in China. Within 3 months, the World Health Organization defined COVID-19 as a pandemic, with more than 370,000 cases and 16,000 deaths worldwide. In consideration of the crucial role of diagnostic testing during COVID-19, the aim of this technical note was to provide a complete synthesis of approaches implemented for the management of suspected or confirmed COVID-19 patients.Key findingsThe planning of a robust plan to prevent the transmission of the virus to patients and department staff members should be fundamental in each radiology service. Moreover, the speed of spread and the incidence of the pandemic make it necessary to optimize the use of personal protective devices and dedicated COVID-19 equipment, given the limited availability of supplies.ConclusionIn the management of radiographic and CT imaging, staff should take special precautions to limit contamination between patients and other patients or professionals.Implications for practiceAn isolated imaging room should be dedicated to suspected or confirmed COVID-19 cases, including radiography and CT scanners. This paper will provide guidance concerning disposable protective gear to be utilized, as well as on the cleaning and sanitation of radiology room and equipment.     

The American College of Radiology Fluoroscopy Dose Index Registry Pilot: Technical Considerations and Dosimetric Performance of the Interventional Fluoroscopes

PurposeTo characterize the accuracy and consistency of fluoroscope dose index reporting and report rates of occupational radiation safety hardware availability and use, trainee participation in procedures, and optional hardware availability at pilot sites for the American College of Radiology (ACR) Fluoroscopy Dose Index Registry (DIR).Materials and MethodsNine institutions participated in the registry pilot, providing fluoroscopic technical and clinical practice data from 38 angiographic C-arm–type fluoroscopes. These data included measurements of the procedure table and mattress transmission factors and accuracy measurements of the reference-point air kerma (K_a,r) and air kerma–area product (P_KA). The accuracy of the radiation dose indices were analyzed for variation over time by 1-way analysis of variance (ANOVA). Sites also self-reported information on availability and use of radiation safety hardware, hardware configuration of fluoroscopes, and trainee participation in procedures.ResultsAll K_a,r and P_KA measurements were within the ±35% regulatory limit on accuracy. The mean absolute difference between correction factors for a given system in fluoroscopic and acquisition mode was 0.03 (95% confidence interval, 0.03–0.03). For the 28 fluoroscopic imaging planes that provided data for 3 time points, ANOVA yielded an F value of 0.134 with an F-critical value of 3.109 (P = .875).ConclusionsThis publication provides the technical and clinical framework pertaining to the ACR Fluoroscopy DIR pilot and offers necessary context for future analysis of the clinical procedure radiation-dose data collected.     

A Survey of Interventional Radiologists Regarding the Use of Morbidity and Mortality Conferencing in Departmental Quality Improvement Programs

PurposeTo investigate the degree to which morbidity and mortality (M&M) conferencing is utilized in interventional radiology (IR), identify impediments to its adoption, and assess the experience of those using this tool.Materials and MethodsMembers of the Society of Interventional Radiology (SIR) were offered a 9-question survey of practices and experiences regarding M&M conferencing within their quality assessment (QA) programs.ResultsAmong 604 respondents, 37.8% were university-based practitioners and 60% were from outside of university practices. Of all respondents, 43% reported practicing 100% IR, with 28.5% practicing IR 75%–99% and 11% practicing IR <50% of the time. The use of M&M conferencing was significantly greater in university practices (90.7%) than in nonuniversity practices (37.1%) and among practitioners performing at least 75% IR (71.2%) than among those practicing <75% (28.8%). The conferences were held monthly (66.6%) or more often, and the majority (56%) of the events identified were scored using the SIR severity score. Approximately 20% of M&M conferences were multidisciplinary, shared most commonly with vascular surgery. The reasons cited for not using M&M included the lack of time and the logistical challenges of the process. However, among those who participate in M&M conferences, the QA goals of the conference were met at very high rates.ConclusionsM&M conferencing is well established in university IR programs and among full-time practitioners but much less so elsewhere. For those sites that do not utilize M&M conferencing, there may be a considerable benefit to addressing the obstacles that are limiting their implementation of this tool.     

Distal Radial Artery Access for Noncoronary Endovascular Treatment Is a Safe and Feasible Technique

PurposeTo evaluate safety and feasibility of distal radial artery (DRA) access for noncoronary interventional radiology procedures.Materials and MethodsAll interventional radiology procedures by means of DRA puncture from July 2017 to August 2018 were retrospectively reviewed. Eighty-two punctures in 56 patients were included, mostly in male patients (84% vs 16%). Mean age was 67.8 years (range, 33.3–87.3 years); mean height was 172 cm (range, 142–190 cm); and mean weight was 83 kg (range, 43–120 kg). Procedural characteristics, technical success, and complication rates were gathered from the medical records and follow-up ultrasound when available. Prerequisites for DRA access were adequate radioulnar collateral circulation, sufficient radial artery diameter, and informed consent in patients initially intended for conventional transradial access.ResultsProcedures included transarterial chemoembolization (n = 34), yittrium-90 pretreatment angiography (n = 21), yittrium-90 administration (transarterial radioembolization; n = 20), and embolization of visceral organs (n = 7). Both 4-Fr (n = 35) and 5-Fr (n = 46) sheaths were used. Technical success of DRA access was 97.6%, with conversion to transfemoral access in 2 cases (2.4%). No major complications were reported as a result of DRA access.ConclusionDRA access is a feasible and safe technique for abdominal interventional radiology embolization procedures. No radial artery occlusion or other major complications were observed in patients who underwent follow-up ultrasound.     

Public Awareness of Interventional Radiology: Population-Based Analysis of the Current State of and Pathways for Improvement

PurposeTo evaluate the awareness of interventional radiology (IR) among the public and identify methods for improvement.Materials and MethodsParticipants (N = 1,000) were anonymously surveyed using Amazon’s Mechanical Turk crowdsourcing platform about medical and IR-specific knowledge, preferred methods of acquisition of medical information, and suggestions for improving awareness of IR. The survey consisted of 69 questions, including both Likert Scale and free text questions.ResultsOf the participants, 92% preferred undergoing a minimally invasive procedure over surgery. However, 39.8% recognized IR as a medical specialty, and less than 50% of these participants correctly identified IR as procedurally oriented. Of those who discussed or underwent an IR procedure (n = 113), most were also offered to undergo the procedure performed by a surgeon (n = 66). Furthermore, 71% (n = 20) of those who underwent the procedure performed by a surgeon reported that lack of awareness of IR played a role in their decision. Almost half of the respondents (n = 458) were interested in learning more about IR, particularly the diseases treated and procedures performed (42% and 37%, respectively). Short (<10-minute) educational videos and increased patient education by primary care providers (PCPs) were among the most suggested ways to improve awareness. Regarding the ambiguity of the name “interventional radiology,” most respondents (n = 555) reported this to be true, and “minimally invasive radiologist” was the most preferred alternative (21.18%).ConclusionsLack of awareness of IR may underlie underutilization. When presented with the knowledge that IR improves patient outcomes, minimally invasive procedures by an interventional radiologist are more often desired by the public than surgical options. Educational videos and patient education by PCPs may increase awareness of IR.     

Custom 3-Dimensional Printed Ultrasound-Compatible Vascular Access Models: Training Medical Students for Vascular Access

PurposeTo generate 3-dimensional (3D) printed ultrasound (US)-compatible vascular models (3DPVAM) and test them for noninferiority in training medical students in femoral artery access.Materials and MethodsA 3DPVAM of normal femoral artery (FA) anatomy was developed from an anonymized computerized tomography (CT) examination. Students were randomized to a 3DPVAM or a commercial model (CM) simulation experience (SE) for US-guided FA access. Students completed a pre-SE questionnaire ranking their self-confidence in accessing the artery on a 5-point Likert scale. A standardized SE was administered by interventional radiology faculty or trainees. Students completed a post-SE questionnaire ranking comfort with FA access on a Likert scale. Student questionnaire results from the 3DPVAM group were compared with those from the CM group by using chi-square, Wilcoxon signed-rank, and noninferiority analyses.ResultsTwenty-six and twenty-three students were randomized to 3DPVAM and commercial model training, respectively. A total of 76.9% of 3DPVAM trainees and 82.6% of CM trainees did not feel confident performing FA access prior to the SE. In both groups, training increased student confidence by 2 Likert points (3DPVAM: P < 0.001; CM P < 0.001). The confidence increase in 3DPVAM trainees was noninferior to that in CM trainees (P < 0.001).ConclusionsGeneration of a custom-made 3DPVAM is feasible, producing comparable subjective training outcomes to those of CM. Custom-made 3D-printed training models, including incorporation of more complex anatomical configurations, could be used to instruct medical students in procedural skills.     

Hemodialysis Catheters in Infants: A Retrospective Single-Center Cohort Study

PurposeEvaluate technical aspects and outcomes of insertion/maintenance of hemodialysis (HD) central venous catheter (CVC) during infancy.Materials and MethodsSingle-center retrospective study of 29 infants who underwent 49 HD-CVC insertions between 2002 and 2016. Demographics, procedural, and post-procedural details, interventional radiology (IR) maintenance procedures, technical modifications, complications, and outcomes were evaluated. Technical adjustments during HD-CVC placement to adapt catheter length to patient size were labeled “modifications.” CVCs requiring return visit to IR were called IR-maintenance procedures. Mean age and weight at HD-CVC insertion were 117 days and 4.9 kg.ResultsOf the 29 patients, 13 (45%) required renal-replacement-therapy (RRT) as neonates, 10 (34%) commenced RRT with peritoneal dialysis (PD), and 19 (66%) with HD. Fifteen nontunneled and 34 tunneled HD-CVCs were inserted while patients were ≤1 year. Technical modifications were required placing 25/49 (51%) HD-CVCs: 5/15 (33%) nontunneled and 20/34 (59%) tunneled catheters (P = .08). Patients underwent ≤6 dialysis-cycles/patient during infancy (mean 2.3), and a mean of 4.1 and 49 HD-sessions/catheter for nontunneled and tunneled HD-CVCs, respectively. Mean primary and secondary device service, and total access site intervals for tunneled HD-CVCs were 75, 115, and 201 days, respectively. A total of 26 of 49 (53%) patients required IR-maintenance procedures. Nontunneled lines had greater catheter-related bloodstream infections per 1,000 catheter-days than tunneled HD-CVCs (9.25 vs. 0.85/1,000 catheter days; P = .02). Nineteen patients (65%) survived over 1 year. At final evaluation (December 2017): 8/19 survived transplantation, 5/19 remained on RRT, 2/19 completely recovered, 1/19 lost to follow-up, and 3 died at 1.3, 2, and 10 years.ConclusionsPlacement/maintenance of HD-CVCs in infants pose specific challenges, requiring insertion modifications, and IR-maintenance procedures to maintain function.     

Single-Use versus Reusable Endoscopes for Percutaneous Biliary Endoscopy with Lithotripsy: Technical Metrics,Clinical Outcomes,and Cost Comparison

PurposeTo compare procedure and fluoroscopy time, technical and clinical success, and costs between single-use and reusable endoscopes in patients undergoing percutaneous biliary endoscopy (PBE) with lithotripsy.Material and MethodsThirty-four patients (67 procedures) were retrospectively included in the study. The patients were treated with PBE for gallstone removal from October 24, 2014, to February 12, 2020, using reusable (28 procedures) or single-use (39 procedures) endoscopes. The procedure time, fluoroscopy time, technical success rate (accessing the biliary system and locating the gallstone), clinical success rate (at least partial gallstone removal), complication rate, and cost of use were compared between the procedures.ResultsThe mean (± standard deviation) procedure time was not significantly different between single-use (136 minutes ± 45) and reusable endoscopes (136 minutes ± 51) (P = .47). The mean fluoroscopy time was significantly shorter for single-use endoscopes (11 minutes ± 8.4) than for reusable endoscopes (18 minutes ± 12) (P = .01). When comparing single-use versus reusable endoscopes, the technical success (95% [n = 37] vs 93% [n = 26]) and the clinical success (90% [n = 35] vs 75% [n = 21]) rates were not significantly different (both, P > .05). Only 1 complication was noted in the reusable endoscope group (P = .42). The cost per case was lower for single-use ($1,500) than for reusable ($3,987) endoscope procedures, primarily due to differences in capital costs and repair costs.ConclusionsSingle-use endoscopes offer the potential for lower patient radiation exposure and lower cost per case, which may reduce the financial barriers to offering PBE in interventional radiology practices. The clinical and technical success rates did not differ by endoscope type.     

Cost-Effectiveness of a Guided Peripherally Inserted Central Catheter Placement System: A Single-Center Cohort Study

PurposeTo assess the cost-effectiveness of peripherally inserted central catheter (PICC) placements using an ultrasound and electrocardiogram-guided system versus external measurements and confirmatory chest X-rays (CXRs).Materials and MethodsSixty-eight guided PICC placements were performed in 63 outpatients (mean age, 43 ± 13 years; 50% male) and compared to 68 propensity score-matched PICC placements (mean age, 44 ± 13 years; 56% male) performed using external measurements by the same operators. Post-placement CXRs were used to confirm final catheter tip positioning. Cohorts were compared in terms of repositioning rates, desired tip positioning rates (in the lower third of the superior vena cava or at the cavoatrial junction), and estimated cost per PICC positioned as desired using manufacturer quotes, Medicare reimbursement rates, and hourly wages for staff time. Agreement between tip positioning according to the guided system versus CXR was also assessed.ResultsGuided PICC placements required less repositioning (1.5% vs 10.3%, P = .03) and resulted in more catheters positioned as desired (86.8% vs 67.6%, P = .01) than the external measurement approach. The cost per PICC positioned as desired was lower for guided placements ($318.54 vs $381.44), suggesting that the guided system was cost-effective in this clinical setting. Guided system-CXR agreement for tip position was poor (κ=0.25, P = .002) due to tips being slightly farther from the cavoatrial junction on CXR than indicated by the guided system.ConclusionsThe guided PICC placement system was cost-effective in outpatients treated by a single division of interventional radiology at an academic institution.     

Reductions in Reimbursement and Relative Value Units for Interventional Radiology Procedures: Trends from 2011 to 2021 Compared with Those for Other Physician Specialties

PurposeTo compare recent trends in Medicare reimbursement and relative value units (RVUs) for interventional radiology (IR) procedures similar to those performed by non-IR specialties.Materials and MethodsData from the Centers for Medicare and Medicaid Services Physician Fee Schedule for facility reimbursement and RVU component values for 23 commonly performed single Current Procedural Terminology IR procedures were compared with similar procedures or procedures for similar indications performed by non-IR specialties between 2011 and 2021.ResultsThe work RVU component decreased in 18 of 23 (78.3%) IR procedures compared with 6 of 23 (26.1%) similar procedures performed by non-IR specialties. The largest change in single RVU component was a 19.2% reduction in practice expense RVU for IR compared with a 16.5% reduction for similar procedures performed by non-IR specialties.ConclusionsAs a specialty, IR experienced a disproportionately greater reduction in reimbursement and RVU valuation for a range of comparable procedures performed by non-IR specialties.     

Improved Utilization Following Conversion of a Fluoroscopy Suite to Hybrid CT/Angiography System

PurposeTo assess changes in operational utilization following conversion of a single IR suite to a hybrid CT/angiography (Angio-CT) system at an academic tertiary care center.Materials and MethodsThe total number of interventional procedures and diagnostic CT examinations performed in 29 rooms (20 diagnostic radiology, 7 IR, 2 shared between divisions) was calculated in the 24 months before conversion of an IR suite to Angio-CT and 12 months after conversion. The total number of IR procedures (global IR/month) and diagnostic CT scans per month (global CT/month) in both before and after conversion periods was calculated and defined as baseline institutional growth. This was compared against the change in the number of IR procedures performed in the before and after periods in the converted room (Angio-CT/month) as well as the number of diagnostic CT scans performed in the shared rooms (shared CT/month).ResultsThe percent change in global CT and global IR from the before to the after periods was 39.2% and 3.1%, respectively. Shared CT per month and Angio-CT per month increased by 46.7% and 12.0% across the same time periods, respectively. The ratio of the percent increase in Angio-CT per month to percent increase in global IR per month was 3.87. The ratio of the percent increase in shared CT per month to percent increase in global CT per month was 1.19.ConclusionsOperational utilization improved in both diagnostic radiology and IR sections following conversion of a conventional fluoroscopic IR suite to an Angio-CT room.
