The Prevalence of Financial Conflict of Interest Disclosures by Endovascular Specialists on X (Twitter).

PURPOSE: To evaluate conflicts of interest (COIs) among interventional radiologists and related specialties who mention specific devices or companies on the social media (SoMe) platform X, formerly Twitter. MATERIALS AND METHODS: In total, 13,809 posts between October 7, 2021, and December 31, 2021, on X were evaluated. Posts by U.S. interventional radiologists and related specialties who mentioned a specific device or company were identified. A positive COI was defined as receiving a payment from the device manufacturer or company within 36 months prior to posting. The Center for Medicare & Medicaid Services Open Payment database was used to identify financial payments. The prevalence and value of COIs were assessed and compared between posts mentioning a device or company and a paired control group using descriptive statistics and chi-squared tests and independent t tests. RESULTS: Eighty posts containing the mention of 100 specific devices or companies were evaluated. COIs were present in 53% (53/100). When mentioning a specific device or product, 40% interventional radiologists had a COI, compared with 62% neurosurgeons. Physicians who mentioned a specific device or company were 3.7 times more likely to have a positive COI relative to the paired control group (53/100 vs 14/100; P < .001). Of the 31 physicians with a COI, the median physician received $2,270. None of the positive COIs were disclosed. CONCLUSIONS: Physicians posting on SoMe about a specific device or company were more likely to have a financial COI than authors of posts not mentioning a specific device or company. No disclosure of any COI was present in the posts, limiting followers' ability to weigh potential bias.

Development of a Medical Social Media Ethics Scale and Assessment of #IRad, #CardioTwitter, and #MedTwitter Posts: Mixed Methods Study.

BACKGROUND: Social media posts by clinicians are not bound by the same rules as peer-reviewed publications, raising ethical concerns that have not been extensively characterized or quantified. OBJECTIVE: We aim to develop a scale to assess ethical issues on medical social media (SoMe) and use it to determine the prevalence of these issues among posts with 3 different hashtags: #MedTwitter, #IRad, and #CardioTwitter. METHODS: A scale was developed based on previous descriptions of professionalism and validated via semistructured cognitive interviewing with a sample of 11 clinicians and trainees, interrater agreement, and correlation of 100 posts. The final scale assessed social media posts in 6 domains. This was used to analyze 1500 Twitter posts, 500 each from the 3 hashtags. Analysis of posts was limited to original Twitter posts in English made by health care professionals in North America. The prevalence of potential issues was determined using descriptive statistics and compared across hashtags using the Fisher exact and χ2 tests with Yates correction. RESULTS: The final scale was considered reflective of potential ethical issues of SoMe by participants. There was good interrater agreement (Cohen κ=0.620, P<.01) and moderate to strong positive interrater correlation (=0.602, P<.001). The 6 scale domains showed minimal to no interrelation (Cronbach α=0.206). Ethical concerns across all hashtags had a prevalence of 1.5% or less except the conflict of interest concerns on #IRad, which had a prevalence of 3.6% (n=18). Compared to #MedTwitter, posts with specialty-specific hashtags had more patient privacy and conflict of interest concerns. CONCLUSIONS: The SoMe professionalism scale we developed reliably reflects potential ethical issues. Ethical issues on SoMe are rare but important and vary in prevalence across medical communities.

Private Equity and Radiology: Productive Partnership or Inherently Misaligned?

Private equity acquisition of medical groups and health care organizations is becoming increasingly important in medicine and is a trend that is likely to continue for the foreseeable future. Some question the ethical implications of private equity acquisitions, since the clear goal of such organizations is maximizing profitability, which may or may not be in the best interests of either the patient population or the provider group. This article will describe the role of private equity in the medical marketplace, with a focus on the role of private equity in radiology and interventional radiology specifically. Additionally, this article will explore this growing trend in the radiology marketplace and its anticipated effects upon patient care and professional satisfaction for radiologists.

Consent in Interventional Radiology-How Can We Make It Better?

Informed consent is an important part of the clinician-patient relationship. However, studies suggest consent practices tend to be limited in consistency and completeness. This may be particularly challenging for interventional radiology given more limited public awareness and the often fast-paced, dynamic nature of our practices. This article reviews these challenges as well as ideal consent practices and potential approaches to improve consent in interventional radiology.

Patient Decision Aids Before Informed Consent Conversations for Image-Guided Procedures: Controlled Trials at Two Institutions.

BACKGROUND. Patient decision aids (PDAs) improve informed consent practices. Available PDAs for image-guided procedures are of limited quality. OBJECTIVE. The purpose of this article was to evaluate the impact of PDAs on understanding and satisfaction among patients undergoing informed consent conversations before outpatient image-guided procedures. METHODS. This prospective study included patients awaiting an interventional radiology clinic visit to discuss and obtain informed consent for an image-guided procedure. The study was conducted at two academic medical centers (site A, visits from August 2020 to July 2021; site B, visits from January 2021 to October 2021). Patients were assigned systematically at site A and randomly at site B to electronically receive or not receive a two-page PDA before the visit. PDAs described procedures and their benefits, risks, and alternatives at a sixth- to eighth-grade health literacy level and were vetted by diverse patient focus groups. Patients completed a postvisit survey (site A, by telephone; site B, online) assessing understanding of the procedure and satisfaction with the consent conversation using 5-point scales. Data were pooled between sites. RESULTS. The study included 105 patients (59 men, 46 women; median age, 67 years; 51 from site A, 54 from site B; 53 who received PDA, 52 who did not). Survey response rate was 100% (51/51) at site A and 67% (62/92) at site B. Patients who received, versus did not receive, a PDA reported greater understanding of benefits (4.5 vs 4.0, p < .001), risks (4.4 vs 3.6, p < .001), and alternatives (4.0 vs 3.3, p < .001), and of what procedures involved (4.4 vs 4.1, p = .02) and were more likely to feel that they were provided with enough time with the clinician (4.7 vs 4.5, p = .03), listened to carefully (4.8 vs 4.4, p < .001), free to choose any option including not to have the procedure (4.7 vs 4.3, p < .001), given enough time to make a decision (4.8 vs 4.3, p < .001), encouraged to ask questions (4.8 vs 4.5, p < .001), and had questions answered (4.8 vs 4.4, p = .001). CONCLUSION. Well-vetted plain-language PDAs provided before image-guided procedure consent conversations improve patients' self-perceived understanding of the procedure and satisfaction with the conversation. CLINICAL IMPACT. PDAs can be implemented effectively without requiring additional clinician time or effort.

Confirmation of Ectopic Pancreatic Tissue: A Novel Use for 18 F-Fluciclovine PET.

ABSTRACT: This case features a 21-year-old woman with a history of ulcerative colitis who was incidentally found to have a para-jejunal mass when she presented with an ulcerative colitis flare. The mass was further characterized on MR enterography as most likely representing ectopic pancreatic tissue. Given the normal intense pancreatic uptake of 18 F-fluciclovine, PET/CT was subsequently used to confirm that the mass represented ectopic pancreatic tissue.

Opportunities for Excellence in Interventional Radiology Training: A Qualitative Study.

OBJECTIVE: The training experience in interventional radiology (IR) residency programs varies widely across the country. The introduction of an IR training pathway has provided the impetus for the specialty to better define outstanding IR education and for programs to rethink how their curricula prepare IR trainees for real-world practice. Although ACGME competencies define several training components that are necessary for independent practice, few quantitative or qualitative studies have explored current perceptions on what constitutes optimal IR training. Our goal was to qualitatively explore program training features deemed most important to adequately prepare IR physicians for practice and assess whether there were differences in perception between academic and nonacademic practices. METHODS: Semistructured interviews were conducted with 71 IR attending physicians, trainees, and support staff across the United States. All interviews were performed over the telephone by a single researcher for consistency and systematically coded by two independent coders for common themes. Frequency and prevalence of themes and facilitating features were analyzed. RESULTS: The most frequently perceived facilitating features included longitudinal patient care experience, practice-building education, interspecialty collaboration exposure, broad case mix, clinical decision-making exposure, diagnostic radiology training, procedural skills training, and graduated autonomy. Comparing nonacademic versus academic practice settings, significantly more nonacademic IR attending physicians expressed practice-building education (prevalence 72% versus 42%, frequency 2.2 versus 0.7, P < .01) as an important training experience. DISCUSSION: An understanding of perceived facilitating features for optimal IR trainee preparation, including potentially different needs between academic and nonacademic practices, can help programs prepare their trainees for a successful transition into practice.

Tunneled Peritoneal Catheter vs Repeated Paracenteses for Recurrent Ascites: A Cost-Effectiveness Analysis.

PURPOSE: To compare the cost-effectiveness of tunneled peritoneal catheter (TPC) versus serial large-volume paracenteses (LVP) for patients with recurrent ascites. MATERIALS AND METHODS: Retrospective, single-institution analysis of 100 consecutive patients undergoing LVP and eventual TPC placement (2015-2018) was performed with extraction of procedural complications and hospital admissions. LVPs were associated with 17 adverse events (AEs) while only 9 AEs occurred after TPC placement. While undergoing routine LVP, the patients had 30 hospitalizations monthly (177 days in total) and 10 hospitalizations monthly (51 days) after TPC placement. A cost-effectiveness analysis with Markov modeling was performed comparing TPC and LVP. Costs were based on Medicare reimbursement rates. Statistical analyses include base case calculation, Monte Carlo simulations, and deterministic sensitivity analyses. RESULTS: TPC placement was the dominant strategy with a comparable health benefit of 0.08060 quality-adjusted life-years (QALY) (LVP: 0.08057 QALY) at a lower cost of $4151 (LVP: $8401). Probabilistic sensitivity analysis showed TPC was superior in 97.49% of simulations. Deterministic sensitivity analysis demonstrated the superiority of TPC compared to LVP if the TPC complication rate was < 9.47% per week and the complication rate for LVP was > 1.32% per procedure. TPC was more cost-effective when its procedural cost was < $5427 (base case: 1174.5), and remained as such when the cost of LVP was varied as much as $10,000 (base case: $316.48). CONCLUSION: In this study, TPC was more cost-effective than LVP in patients with recurrent ascites due to the reduced risk of infection, emergency department visits, and length of hospitalization stays.

The power of proximity: Effects of a multidisciplinary fibroid clinic on inter-specialty perceptions and practice patterns.

BACKGROUND: Multidisciplinary collaboration has generally been shown to have positive effects on healthcare but can be difficult to facilitate. This study assessed the effects of a multidisciplinary fibroid clinic on practice patterns and clinician perceptions to better understand drivers of interspecialty collaboration. MATERIALS AND METHODS: Annual rates of hysterectomies, myomectomies, and uterine fibroid embolizations (UFEs) performed in an urban healthcare system were collected from 2012-2019. Rates of each procedure were compared over time before and after launching a multidisciplinary fibroid clinic at the academic medical center. Referral rates were also compared. The gynecologists and interventional radiologists (IRs) involved in the clinic were interviewed 2 years prior to and after the clinic launch about their approaches to fibroids and perceptions of others who treat this condition. A phenomenological approach was used to identify and compare themes within the interviews by two researchers with excellent inter-rater agreement (κ = 0.80). RESULTS AND DISCUSSION: Annual rates of fibroid procedures increased over time (p<0.01) but the relative number of UFEs decreased (p = 0.01). UFE referrals by the clinic gynecologists significantly increased as did the number of combined fibroid procedures (p<0.01). However, the rates of one fibroid procedure relative to others were not different between the clinic and rest of the healthcare system (p = 0.55). Specialty-specific perceptions of fibroid treatments and inter-specialty dynamics did not change. Despite this, clinicians unanimously perceived the clinic and post-clinic practice patterns as positive and distinct from their previous work and relationships between gynecology and IR elsewhere. Limitations of this study included its single clinic design and potential confounder of differences in advertising pre- versus post-clinic. CONCLUSION: Creating the right practice environment may be more important for fostering inter-specialty collaboration and work satisfaction than shared mental models or procedural volumes in certain practice settings.

Cost-effectiveness of tunneled peritoneal catheters versus repeat paracenteses for recurrent ascites in gynecologic malignancies.

OBJECTIVE: To compare the cost-effectiveness of tunneled peritoneal catheter (TPC) versus repeated large-volume paracentesis (LVP) for patients with recurrent ascites secondary to gynecological malignancy. METHODS: A retrospective cohort study was performed at a single institution from 2016 through 2019 of patients with recurrent ascites from gynecologic malignancies that underwent either TPC or LVP. Data on procedural complications and hospital admissions were extracted. A cost-effectiveness analysis with Markov modeling was performed comparing TPC and LVP. Statistical analyses include base case calculation, Monte Carlo simulations and deterministic sensitivity analyses. RESULTS: There were no significant differences between the cohorts in the average number of hospital days (p = 0.21) or emergency department visits (p = 0.69) related to ascites. Palliative care was more often involved in the care of patients who had a TPC. The base case calculation showed TPC to be the more cost-effective strategy with a slightly lower health benefit (0.22980 versus 0.22982 QALY) and lower cost ($3043 versus $3868) relative to LVP (ICER of LVP compared to TPC: $44,863,103/QALY). Probabilistic sensitivity analysis showed TPC was the more cost-effective strategy in 8028/10,000 simulations. Deterministic sensitivity analysis showed TPC to be more cost-effective if its complication risk was >0.81% per 22 days or its procedural cost of TPC insertion was >$1997. When varying the cost of complications, TPC was more cost-effective if the cost of its complication was less than $49,202. CONCLUSIONS: TPC is the more cost-effective strategy when compared to LVP in patients with recurrent ascites from gynecological malignancy.
