RESUMO
INTRODUCTION: The purpose of this study is to evaluate emotional intelligence in doctor of pharmacy (PharmD) students at various points in the curriculum. METHODS: This was a cross-sectional, single site, observational study that included first- through fourth-year PharmD students, conducted from December 2021 to April 2022. The study used the Emotional Quotient Inventory, version 2.0 (EQ-i 2.0) to obtain student emotional intelligence scores. A survey in QualtricsSM (SAP) was used to obtain baseline characteristics. The primary endpoint was the mean total EQ-i 2.0 scores comparing professional years. Secondary endpoints included mean EQ-i 2.0 scores in the composite scales of self-perception, self-expression, interpersonal, decision-making and stress-management. Change in EQ-i 2.0 scores was evaluated using descriptive statistics and analysis of variance. Multivariable regression analysis identified associations between baseline characteristics and EQ-i 2.0 scores. RESULTS: A total of 137 (137/485, 28.2%) students completed the EQ-i 2.0 assessment. The mean (SD) total EQ-i 2.0 scores were 98.1 (15.5), 92.2 (15.9), 92.4 (12.9), and 103.5 (13.1), for first-, second- (P2), third- (P3), and fourth-year (P4) students, respectively. A statistically significant increase in total EQ-i 2.0 scores was noted in P4 students compared to P2 and P3 students. Work experience and leadership roles within student organizations may be associated with an increase in total EQ-i 2.0 scores. CONCLUSIONS: Emotional intelligence varied among students in different years of the pharmacy curriculum. P4 students were found to have the highest average emotional intelligence. The effect of curricular and co-curricular components on emotional intelligence development warrants further exploration.

Objectives: To re-examine the use of non-carbapenems (NCBPs), specifically piperacillin/tazobactam and cefepime, for ESBL-producing Enterobacterales (ESBL-E) urinary tract infections (UTIs). Patients: Retrospective cohort study of adults hospitalized between January 2016 and June 2020 with pyuria on urinalysis, a urine culture positive for ESBL-E treated with a study antibiotic (meropenem, ertapenem, cefepime or piperacillin/tazobactam) and did not meet criteria for study exclusion. Methods: To compare carbapenems (CBPs) with cefepime or piperacillin/tazobactam for the treatment of ESBL-E UTI. The primary outcome was clinical cure, defined as complete resolution of signs and symptoms of infection. Secondary outcomes included in-hospital mortality, recurrence within 30â days and resistance emergence within 30â days. Results: One-hundred and thirty-three patients were included, based on definitive therapy received; 69 (51.9%) received CBP and 64 (48.1%) received NCBP therapy. Of the total patient population, 17 (12.8%) were admitted to the ICU, 84 (63.1%) had a complicated UTI and 64 (48.1%) had pyelonephritis. There was no difference in clinical cure between the CBP and NCBP groups (95.7% versus 96.9%, Pâ=â0.999). Additionally, no differences in secondary outcomes were observed. Conclusions: When compared with CBPs, cefepime and piperacillin/tazobactam resulted in similar clinical cure, in-hospital mortality, recurrence and resistance emergence in the treatment of ESBL-E UTI.
RESUMO
INTRODUCTION: Clinical outcomes of implantable port catheters (IPCs) placed via alternative veins such as the external jugular and cervical collaterals have not been well established. This investigation evaluates the short- and long-term outcomes of IPCs inserted via alternate cervical veins (ACV) compared to traditionally inserted IPCs via the internal jugular vein (IJV). MATERIALS AND METHODS: A total of 24 patients who received an IPC between 2010 and 2020 via an ACV-defined as the external jugular vein, superficial cervical vein, or unnamed collateral veins-were identified. Based on power analysis, a matched control group of 72 patients who received IPCs via the IJV was identified. Non-inferiority analysis for port complications was performed between the two groups based on the selected non-inferiority margin of 20%. Secondary end points included complication-free survival and comparison of complications by the time at which they occurred. RESULTS: ACV access was non-inferior to traditional access for overall complications. Alternate access resulted in fewer complications than traditional access with an estimated reduction of - 7.0% [95% CI - 23.6%, 39.7%]. There was no significant difference in peri-procedural and post-procedural complications between the two groups. Complication-free survival was also equivalent between the two groups. CONCLUSION: IPC placement via ACVs was non-inferior to IPCs placed via traditional access through the IJV. When abnormal pathology obviates the use of IJV access, other cervical veins may be considered prior to seeking alternate locations such as femoral, translumbar, inferior vena cava, and hepatic veins.

Objective: To re-examine the use of noncarbapenems (NCBPs), specifically piperacillin-tazobactam (PTZ) and cefepime (FEP), for extended-spectrum beta-lactamase-producing Enterobacterales bloodstream infections (ESBL-E BSIs). Design: Retrospective cohort study. Setting: Tertiary-care, academic medical center. Patients: The study included patients hospitalized between May 2016 and May 2019 with a positive blood culture for ESBL-E. Patients were excluded if they received treatment with antibiotics other than meropenem, ertapenem, PTZ, or FEP. Patients were also excluded if they were aged <18 years, received antibiotics for <24 hours, were treated for polymicrobial BSI, or received concomitant antibiotic therapy for a separate gram-negative infection. Methods: We compared CBPs with FEP or PTZ for the treatment of ESBL-E BSI. The primary outcome was in-hospital mortality. Secondary outcomes included clinical cure, microbiologic cure, infection recurrence, and resistance development. Results: Data from 114 patients were collected and analyzed; 74 (65%) patients received carbapenem (CBP) therapy and 40 (35%) patients received a NCBP (30 received FEP and 10 received PTZ). The overall in-hospital mortality was 6% (N = 7), with a higher death rate in the CBP arm than in the N-CBP arm, (8% vs 3%; P = .42). No difference in mortality was detected between subgroups with Pitt bacteremia score ≥4, those requiring ICU admission, those whose infections were cause by a nongenitourinary source or causative organism (ie, 76 had Escherichia coli and 38 had Klebsiella spp). We detected no differences in secondary outcomes between the groups. Conclusion: Compared to CBPs, FEP and PTZ did not result in greater mortality or decreased clinical efficacy for the treatment of ESBL-E BSI caused by susceptible organisms.
RESUMO
BACKGROUND: Enhanced Recovery After Surgery (ERAS) pathways in head and neck cancer (HNC) have shown to improve perioperative outcomes and reduce complications. The longer term implications on adjuvant treatment and survival have not been studied. We hereby report the first study on the impact of an ERAS pathway on return to intended oncologic treatment (RIOT) and overall survival (OS) in HNC. METHODS: 200 patients undergoing head and neck oncologic surgery on an ERAS pathway between March 1, 2016 and March 31, 2019 were matched to controls over the same interval. Demographic, tumor and adjuvant therapy-related data were collected, including time to adjuvant therapy(TAT) and treatment package time(TPT). Risk factors for TAT > 42 days and TPT ≥ 85 days were assessed. OS was compared and risk factors for inferior OS determined. RESULTS: Baseline characteristics including co-morbidities and tumor stage were similar. Of 179 patients planned for adjuvant treatment, there was no difference in RIOT rate (89.0% vs 87.5%, p = 0.753), proportion of TAT > 42 days of surgery (55.6% vs 59.7%, p = 0.642), or TPT ≥ 85 days (48.1% vs 57.1, p = 0.258), for the ERAS and control groups, respectively. On multivariate analysis, alcohol use (OR 3.58; 95 %CI 1.11-11.52) and recurrent disease status (OR 2.88; 95 %CI 1.40-5.93) were independently associated with prolonged TAT. Three-year OS was similar between the ERAS and control groups (73% vs 76%, p = 0.521). CONCLUSION: ERAS has not shown to improve RIOT or OS in the current study. However, its benefit for perioperative outcomes is undeniable and further studies are required on longer term quality and survival outcomes.

PURPOSE: To model the effect of the injection location on the distribution of yttrium-90 (90Y) microspheres in the liver during radioembolization using computational simulation and to determine the potential effects of radial movements of the catheter tip. MATERIALS AND METHODS: Numerical studies were conducted using images from a representative patient with hepatocellular carcinoma. The right hepatic artery (RHA) was segmented from contrast-enhanced cone-beam computed tomography scans. The blood flow was investigated in the trunk of the RHA using numerical simulations for 6 injection position scenarios at 2 sites located at a distance of approximately 5 and 20 mm upstream of the first bifurcation (RHA diameters of approximately 4.6 mm). The 90Y delivery to downstream vessels was calculated from the simulated hepatic artery hemodynamics. RESULTS: Varying the injection location along the RHA and across the vessel cross-section resulted in different simulated microsphere distributions in the downstream vascular bed. When the catheter tip was 5 mm upstream of the bifurcation, 90Y distribution in the downstream branches varied by as much as 53% with a 1.5-mm radial movement of the tip. However, the catheter radial movement had a weaker effect on the microsphere distribution when the injection plane was farther from the first bifurcation (20 mm), with a maximum delivery variation of 9% to a downstream branch. CONCLUSIONS: An injection location far from bifurcations is recommended to minimize the effect of radial movements of the catheter tip on the microsphere distribution.

PURPOSE: To 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 METHODS: Members 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. RESULTS: Among 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. CONCLUSIONS: M&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.

Transarterial radioembolization (TARE) is a locoregional radiopharmaceutical therapy based on the delivery of radioactive 90Y microspheres to liver tumors. The importance of personalized dosimetry to make TARE safer and more effective has been demonstrated in recent clinical studies, stressing the need for quantification of the dose-response relationship to ultimately optimize the administered activity before treatment and image it after treatment. 90Y dosimetric studies are challenging because of the lack of accurate and precise methods but are best realized with PET combined with Monte Carlo simulations and other image modalities to calculate a segmental dose distribution. The aim of this study was to assess the suitability of imaging 90Y PET patients with the total-body PET/CT uEXPLORER and to investigate possible improvements in TARE 90Y PET-based dosimetry. The uEXPLORER is the first commercially available ultra-high-resolution (171 cps/kBq) total-body digital PET/CT device with a 194-cm axial PET field of view that enables the whole body to be scanned at a single bed position. Methods: Two PET/CT scanners were evaluated in this study: the Biograph mCT and the total-body uEXPLORER. Images of a National Electrical Manufacturers Association (NEMA) image-quality phantom and 2 patients were reconstructed using our standard clinical oncology protocol. A late portal phase contrast-enhanced CT scan was used to contour the liver segments and create corresponding volumes of interest. To calculate the absorbed dose, Monte Carlo simulations were performed using Geant4 Application for Tomographic Emission (GATE). The absorbed dose and dose-volume histograms were calculated for all 6 spheres (diameters ranging from 10 to 37 mm) of the NEMA phantom, the liver segments, and the entire liver. Differences between the phantom doses and an analytic ground truth were quantified through the root mean squared error. Results: The uEXPLORER showed a higher signal-to-noise ratio at 10- and 13-mm diameters, consistent with its high spatial resolution and system sensitivity. The total liver-absorbed dose showed excellent agreement between the uEXPLORER and the mCT for both patients, with differences lower than 0.2%. Larger differences of up to 60% were observed when comparing the liver segment doses. All dose-volume histograms were in good agreement, with narrower tails for the uEXPLORER in all segments, indicating lower image noise. Conclusion: This patient study is compelling for the use of total-body 90Y PET for liver dosimetry. The uEXPLORER scanner showed a better signal-to-noise ratio than mCT, especially in lower-count regions of interest, which is expected to improve dose quantification and tumor dosimetry.

BACKGROUND: Enhanced recovery after surgery (ERAS) pathways are well established in certain surgical specialties because findings have shown significant improvements in outcomes. Convincing literature in head and neck cancer (HNC) surgery is lacking. This study aimed to assess the effect of an ERAS pathway on National Surgical Quality Improvement Program (NSQIP)-based occurrences and pain-related outcomes in HNC surgery. METHODS: The study matched 200 patients undergoing head and neck oncologic surgery on an ERAS pathway between 1 March 2016 and 31 March 2019 with control subjects (1:1 ratio) during the same period. Demographic and perioperative data collected from the NSQIP database were extracted. Pain scores and medication usage were electronically extracted from our electronic medical record system and compared. Risk factors for high opioid usage also were assessed. RESULTS: Both groups were statistically similar in baseline characteristics. The ERAS group had fewer planned intensive care unit (ICU) admissions (4% vs. 14%; p < 0.001), a shorter mean hospital stay (7.2 ± 2.3 vs. 8.7 ± 4.2 days; p < 0.001), and fewer overall complications (18.6% vs. 27.0%; p = 0.045). Morphine milligram equivalent requirements over 72 h were significantly reduced during 72 h in the ERAS group (138.8 ± 181.5 vs. 207.9 ± 205.5; p < 0.001). In the multivariate analysis, the risk factors for high opioid analgesic usage included preoperative opioid usage, age younger than 65 years, race, patient-controlled analgesia use, and ICU admission. CONCLUSION: The study findings showed that ERAS in HNC surgery can result in improved outcomes and resource use, and that these results are sustainable. The outcomes described in this report can be further used to optimize ERAS pathways.

Yttrium-90 (90Y) radioembolization is a minimally invasive procedure increasingly used for advanced liver cancer treatment. In this method, radioactive microspheres are injected into the hepatic arterial bloodstream to target, irradiate, and kill cancer cells. Accurate and precise treatment planning can lead to more efficient and safer treatment by delivering a higher radiation dose to the tumor while minimizing the exposure of the surrounding liver parenchyma. Treatment planning primarily relies on the estimated radiation dose delivered to tissue. However, current methods used to estimate the dose are based on simplified assumptions that make the dosimetry results unreliable. In this work, we present a computational model to predict the radiation dose from the 90Y activity in different liver segments to provide a more realistic and personalized dosimetry. Computational fluid dynamics (CFD) simulations were performed in a 3D hepatic arterial tree model segmented from cone-beam CT angiographic data obtained from a patient with hepatocellular carcinoma (HCC). The microsphere trajectories were predicted from the velocity field. 90Y dose distribution was then calculated from the volumetric distribution of the microspheres. Two injection locations were considered for the microsphere administration, a lobar and a selective injection. Results showed that 22% and 82% of the microspheres were delivered to the tumor, after each injection, respectively, and the combination of both injections ultimately delivered 49% of the total administered 90Y microspheres to the tumor. Results also illustrated the nonhomogeneous distribution of microspheres between liver segments, indicating the importance of developing patient-specific dosimetry methods for effective radioembolization treatment.

Triclosan (TCS), employed as an antiseptic and disinfectant, comes into direct contact with humans through a plethora of consumer products and its rising environmental release. We have demonstrated that TCS promotes liver tumorigenesis in mice, yet the biological and molecular mechanisms by which TCS exerts its toxicity, especially in early stages of liver disease, are largely unexplored. When mice were fed a high-fat diet (HFD), we found that fatty liver and dyslipidemia are prominent early signs of liver abnormality induced by TCS. The presumably protective HFD-induced hepatic expression of the metabolic regulator fibroblast growth factor 21 (FGF21) was blunted by TCS. TCS-altered Fgf21 expression aligned with aberrant expression of genes encoding metabolic enzymes manifested as profound systemic metabolic changes that disturb homeostasis of amino acids, fatty acids, and glucose. Using a type 1 diabetic animal model, TCS potentiates and accelerates the development of steatohepatitis and fibrosis, accompanied by increased levels of hepatic lipid droplets and oxidative stress. Analysis of fecal samples revealed that HFD-fed mice exhibited a reduction in fecal species richness, and that TCS further diminished microbial diversity and shifted the bacterial community toward lower Bacteriodetes and higher Firmicutes, resembling changes in microbiota composition in nonalcoholic steatohepatitis (NASH) patients. Using reverse-genetic approaches, we demonstrate that, along with HFD, TCS induces hepatic steatosis and steatohepatitis jointly regulated by the transcription factor ATF4 and the nuclear receptor PPARα, which participate in the transcriptional regulation of the Fgf21 gene. This study provides evidence linking nutritional imbalance and exposure to TCS with the progression of NASH.

Yttrium-90 (90Y) radioembolization is a liver cancer therapy based on 90Y microspheres injected into the hepatic artery. Current dosimetry methods used to estimate the absorbed dose in order to prescribe the 90Y activity to inject are not accurate, which can affect the treatment effectiveness. A new dosimetry based on the hemodynamics simulation of the hepatic arterial tree, CFDose, aimed at overcoming some of the limitations of the current methods. However, due to the expensive computational cost of computational fluid dynamics (CFD) simulations, this method needs to be accelerated before it can be used in real-time during treatment planning. In this paper, we introduce a convolutional neural network model trained with the CFD results of a patient with hepatocellular carcinoma to predict the 90Y distribution under different downstream vasculature resistance conditions. The model performance was evaluated using two metrics, the mean squared error and prediction accuracy. The prediction accuracy showed that the average difference between the actual and predicted data was less than 1%. The proposed model could estimate the 90Y distribution significantly faster than a CFD simulation.

Transarterial embolization is a minimally invasive treatment for advanced liver cancer using microspheres loaded with a chemotherapeutic drug or radioactive yttrium-90 (90Y) that are injected into the hepatic arterial tree through a catheter. For personalized treatment, the microsphere distribution in the liver should be optimized through the injection volume and location. Computational fluid dynamics (CFD) simulations of the blood flow in the hepatic artery can help estimate this distribution if carefully parameterized. An important aspect is the choice of the boundary conditions imposed at the inlet and outlets of the computational domain. In this study, the effect of boundary conditions on the hepatic arterial tree hemodynamics was investigated. The outlet boundary conditions were modeled with three-element Windkessel circuits, representative of the downstream vasculature resistance. Results demonstrated that the downstream vasculature resistance affected the hepatic artery hemodynamics such as the velocity field, the pressure field and the blood flow streamline trajectories. Moreover, the number of microspheres received by the tumor significantly changed (more than 10% of the total injected microspheres) with downstream resistance variations. These findings suggest that patient-specific boundary conditions should be used in order to achieve a more accurate drug distribution estimation with CFD in transarterial embolization treatment planning.
RESUMO
Importance: The opioid epidemic has reignited interest in opioid-sparing strategies in managing pain. However, few studies have focused on opioid use during perioperative care in patients undergoing head and neck surgery with free flap reconstruction. Objectives: To examine the association between multimodal analgesia (MMA) administration and perioperative opioid requirements in patients undergoing head and neck surgery with free flap reconstruction and to investigate whether MMA alters the duration of stay in the postanesthesia care unit (PACU). Design, Setting, and Participants: In this retrospective case-control study, data were collected between April 1, 2016, and December 31, 2017. The study was conducted at a single cancer center in the United States. Participants were 357 patients 18 years or older scheduled for head and neck surgery with free flap reconstruction. Exposures: Patients in the treatment group received oral celecoxib, gabapentin, and/or tramadol hydrochloride before surgery. Control group patients did not receive any of these medications. Main Outcomes and Measures: The amount of opioid administered in the operating room and in the PACU was converted to morphine equivalent daily dose (MEDD) for comparison between the 2 groups. The duration of stay in the PACU was based on the start time and end time of PACU care recorded by nurses in the PACU. Results: In total, 149 patients (mean [SD] age, 60.3 [13.7] years; 104 [69.8%] men) were included in the treatment group, and 208 patients (mean [SD] age, 64.2 [13.6] years; 146 [70.2%] men) were included in the control group. The mean (SD) MEDD of opioid given during surgery was 51.7 (19.8) in the treatment group and 67.9 (24.7) in the control group, for a difference in the means (treatment vs control) of -16.17 (95% CI, -20.81 to -11.52). In the PACU, the mean (SD) MEDD of opioid given was 11.7 (13.3) in the treatment group and 14.9 (15.7) in the control group, for a difference in the means (treatment vs control) of -3.22 (95% CI, -6.40 to -0.03). The MMA treatment remained largely associated with reduced amount of opioid given during surgery, in the PACU, and both combined after controlling for other important factors. Conclusions and Relevance: This case-control study found that the patients who received MMA before head and neck surgery with free flap reconstruction required less opioid medication. The treatment group also had shorter duration of stay in the PACU compared with the control group.

Yttrium-90 (Y-90) transarterial radioembolization uses radioactive microspheres injected into the hepatic artery to irradiate liver tumors internally. One of the major challenges is the lack of reliable dosimetry methods for dose prediction and dose verification. We present a patient-specific dosimetry approach for personalized treatment planning based on computational fluid dynamics (CFD) simulations of the microsphere transport combined with Y-90 physics modeling called CFDose. The ultimate goal is the development of a software to optimize the amount of activity and injection point for optimal tumor targeting. We present the proof-of-concept of a CFD dosimetry tool based on a patient's angiogram performed in standard-of-care planning. The hepatic arterial tree of the patient was segmented from the cone-beam CT (CBCT) to predict the microsphere transport using multiscale CFD modeling. To calculate the dose distribution, the predicted microsphere distribution was convolved with a Y-90 dose point kernel. Vessels as small as 0.45 mm were segmented, the microsphere distribution between the liver segments using flow analysis was predicted, the volumetric microsphere and resulting dose distribution in the liver volume were computed. The patient was imaged with positron emission tomography (PET) 2 h after radioembolization to evaluate the Y-90 distribution. The dose distribution was found to be consistent with the Y-90 PET images. These results demonstrate the feasibility of developing a complete framework for personalized Y-90 microsphere simulation and dosimetry using patient-specific input parameters.

Perioperative difficult airway management is one of the most challenging tasks encountered by anesthesiologists. Awake intubation is considered the gold standard in securing the anticipated difficult airway. Effective communication between the anesthesiologist and patient is vital during awake intubation. A language barrier can significantly hinder success and jeopardize patient safety. We report a case of a monolingual Arabic-speaking patient with a difficult airway who required awake intubation to undergo surgery. Google Translate, a free and accessible translation software application, was used during his awake intubation-we recommend such an approach to be considered to reduce anxiety and facilitate success by providing concise, real-time instruction in the patient's preferred language.

Maternal nutrition is an important factor for infant neurodevelopment. However, prior magnetic resonance imaging (MRI) studies on maternal nutrients and infant brain have focused mostly on preterm infants or on few specific nutrients and few specific brain regions. We present a first study in term-born infants, comprehensively correlating 73 maternal nutrients with infant brain morphometry at the regional (61 regions) and voxel (over 300 000 voxel) levels. Both maternal nutrition intake diaries and infant MRI were collected at 1 month of life (0.9 ± 0.5 months) for 92 term-born infants (among them, 54 infants were purely breastfed and 19 were breastfed most of the time). Intake of nutrients was assessed via standardized food frequency questionnaire. No nutrient was significantly correlated with any of the volumes of the 61 autosegmented brain regions. However, increased volumes within subregions of the frontal cortex and corpus callosum at the voxel level were positively correlated with maternal intake of omega-3 fatty acids, retinol (vitamin A) and vitamin B12, both with and without correction for postmenstrual age and sex (P < 0.05, q < 0.05 after false discovery rate correction). Omega-3 fatty acids remained significantly correlated with infant brain volumes after subsetting to the 54 infants who were exclusively breastfed, but retinol and vitamin B12 did not. This provides an impetus for future larger studies to better characterize the effect size of dietary variation and correlation with neurodevelopmental outcomes, which can lead to improved nutritional guidance during pregnancy and lactation.

PURPOSE: To evaluate the statewide variability in the role of different specialties in lower extremity endovascular revascularization (LEER) and associated submitted charges of care and actual reimbursement for Medicare beneficiaries. METHODS: The 2015 "Medicare Provider Utilization and Payment Data: Physician and Other Supplier" data includes provider-specific information regarding the type of service, submitted average charges of care, and actual average Medicare reimbursements per Healthcare Common Procedure Coding System (HCPCS) code per provider. All HCPCS codes related to LEER were identified. The role of vascular surgery (VS), interventional cardiology (IC), and interventional radiology (IR) in each HCPCS-specific intervention was investigated. RESULTS: In 2015, 4113 providers submitted claims for iliac (n = 13,659), femoropopliteal (n = 52,344), and tibioperoneal (n = 32,688) endovascular revascularizations. In the facility setting, VS performed most of these procedures (52%), followed by IC (32%) and IR (8%). In the outpatient-based lab setting, the proportions were 46%, 36%, and 13%, respectively. Substantial statewide variability in the role of different specialties in LEER was noted. In Maine, Vermont, and Hawaii, all facility claims were submitted by VS, while more than 70% of the claims in Arizona and Utah were submitted by IC. The highest share of LEER for IR was observed in Montana and North Dakota (50%). There was substantial statewide variability in the submitted charges. CONCLUSION: Currently, less than 10% of LEER procedures are being performed by IR. The statewide variability in the submitted charges of care by providers and actual reimbursement for Medicare beneficiaries were investigated in this study.
