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 are 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.

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.

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.

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.

The Bolivian trauma patient's experience: A qualitative needs assessment.

BACKGROUND: Despite a significant burden of injury-related deaths, the Plurinational State of Bolivia (Bolivia), a lower- middle-income country in South America, lacks a formalized trauma system. This study sought to examine Bolivian trauma care from the patient perspective in order to determine barriers to care and targets for improvement. METHODS: Investigators conducted 15 semi-structured interviews with trauma patients admitted at four hospitals in Santa Cruz de la Sierra, Bolivia in June and July of 2016. Interviews were transcribed, translated, and analyzed through content and discourse analysis to identify key themes and perceptions of trauma care. RESULTS: Participants primarily presented with orthopedic injuries due to road traffic incidents and falls. Only one participant reported receiving first aid from a layperson at the scene of injury. Of the 15 participants, 12 did not know any number to contact emergency medical services (EMS). Participants expressed negative views of EMS as well as concerns for slow response times and inadequate personnel and training. Two thirds of participants were initially brought to a hospital without adequate resources to care for their injuries. Participants generally expressed positive views regarding healthcare workers involved in their hospital-based medical care. CONCLUSIONS: This region of Bolivia has a disorganized, underutilized, and distrusted trauma system. In order to increase survival, interventions should focus on improving prehospital trauma care. Potential interventions include the implementation of layperson trauma first responder courses, the establishment of a medical emergency hotline, the unification of EMS, the implementation of basic training requirements for EMS personnel, and public education campaigns to increase trust in EMS.

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

PURPOSE: To 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 METHODS: Sixty-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. RESULTS: Guided 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. CONCLUSIONS: The guided PICC placement system was cost-effective in outpatients treated by a single division of interventional radiology at an academic institution.

Who We Are and What We Can Become: An Analysis of Professional Identity Formation in IR.

PURPOSE: To characterize the unique experiences, values, and perspectives of interventional radiology (IR) fellows. MATERIALS AND METHODS: Sixteen fellows from 4 US vascular and IR programs were interviewed within 2 months of beginning and 2-3 months following their 2015-2016 fellowships about patient interactions, training experiences, and views of IR and other specialties. Interviews were systematically analyzed for dominant themes by using constructivist grounded theory. Four interviews with 2015-2016 interventional cardiology fellows, 16 interviews with IR attending physicians, and online descriptions of IR were also analyzed for context. Themes were compared qualitatively and quantitatively. RESULTS: Interobserver agreement was good for interview themes (κ = 0.70; P < .0001). IR fellows' professional identity emerged primarily from radiologic and surgical interests, with distinct emphasis on being "innovators," "thinking differently," and "needing to adapt and advertise abilities to survive." Fellows' descriptions of patient care were more clinically focused than past interviews with attending physicians (P = .05), but clinical interests common in medical specialties were limited, and descriptions of "nonprocedural patient care" were primarily periprocedural (81%). Descriptions of the future of the field conveyed competing pressures, loose role definition, and disconnect between academic and private-practice IR. CONCLUSIONS: IR fellows share professional interests, views of their field and others, and descriptions of patient care, but there is uncertainty regarding future roles of the specialty and a need for more specific and unified definitions of nonprocedural patient care in IR.

Fostering better policy adoption and inter-disciplinary communication in healthcare: A qualitative analysis of practicing physicians' common interests.

PURPOSE: In response to limited physician adoption of various healthcare initiatives, we sought to propose and assess a novel approach to policy development where one first characterizes diverse physician groups' common interests, using a medical student and constructivist grounded theory. METHODS: In 6 months, a medical student completed 36 semi-structured interviews with interventional radiologists, gynecologists, and vascular surgeons that were systematically analyzed according to constructivist grounded theory to identifying common themes. Common drivers of clinical decision making and professional values across 3 distinct specialty groups were derived from physicians' descriptions of their clinical decision making, stories, and concerns. RESULTS: Common drivers of clinical decision making included patient preference/benefit, experience, reimbursement, busyness/volume, and referral networks. Common values included honesty, trustworthiness, loyalty, humble service, compassion and perseverance, and practical wisdom. Although personal gains were perceived as important interests, such values were easily sacrificed for the good of patients or other non-financial interests. This balance was largely dependent on the incentives and security provided by physicians' environments. CONCLUSIONS: Using a medical student interviewer and constructivist grounded theory is a feasible means of collecting rich qualitative data to guide policy development. Healthcare administrators and medical educators should consider incorporating this methodology early in policy development to anticipate how value differences between physician groups will influence their acceptance of policies and other broad healthcare initiatives.
