RESUMEN

Despite increased attention devoted to diversity, equity, and inclusion (DEI) within academic medicine, representation, lack of workforce and leadership diversity, and bias within medicine remain persistent problems. The purpose of the current study was to understand the current efforts and attention to DEI within academic departments of surgery in the United States. 251 department of surgery websites were reviewed, using a standardized data collection form and scoring procedure, accompanied by a 10 percent fidelity check by an independent reviewer. Only 16% of departments of surgery included DEI-specific information, such as a DEI mission statement or initiatives on their departmental sites, with less than seven percent of departments reporting a DEI committee. Such public information may have implications for recruitment and retention of diverse faculty and trainees, downstream effects for patient care, and could be critical to public accountability to improve diversity and create a culture of equity and inclusion.

RESUMEN

Racial/ethnic disparities persist in patients' access to living donor kidney transplantation (LDKT). This study assessed the impact of having available potential living donors (PLDs) on candidates' receipt of a kidney transplant (KT) and LDKT at two KT programs. Using data from our clinical trial of waitlisted candidates (January 1, 2014-December 31, 2019), we evaluated Hispanic and Non-Hispanic White (NHW) KT candidates' number of PLDs. Multivariable logistic regression assessed the impact of PLDs on transplantation (KT vs. no KT; for KT recipients, LDKT vs. deceased donor KT). A total of 847 candidates were included, identifying as Hispanic (45.8%) or NHW (54.2%). For Site A, both Hispanic (adjusted OR = 2.26 [95% CI 1.13-4.53]) and NHW (OR = 2.42 [1.10-5.33]) candidates with PLDs completing the questionnaire were more likely to receive a KT. For Site B, candidates with PLDs were not significantly more likely to receive KT. Among KT recipients at both sites, Hispanic (Site A: OR = 21.22 [2.44-184.88]; Site B: OR = 25.54 [7.52-101.54]), and NHW (Site A: OR = 37.70 [6.59-215.67]; Site B: OR = 15.18 [5.64-40.85]) recipients with PLD(s) were significantly more likely to receive a LDKT. Our findings suggest that PLDs increased candidates' likelihood of KT receipt, particularly LDKT. Transplant programs should help candidates identify PLDs early in transplant evaluation.

RESUMEN

Hispanic patients receive disproportionately fewer living donor kidney transplants (LDKTs) than non-Hispanic Whites (NHWs). The Northwestern Medicine Hispanic Kidney Transplant Program (HKTP), designed to increase Hispanic LDKTs, was evaluated as a nonrandomized, implementation-effectiveness hybrid trial of patients initiating transplant evaluation at two intervention and two similar control sites. Using a mixed method, observational design, we evaluated the fidelity of the HKTP implementation at the two intervention sites. We tested the impact of the HKTP intervention by evaluating the likelihood of receiving LDKT comparing pre-intervention (January 2011-December 2016) and postintervention (January 2017-March 2020), across ethnicity and centers. The HKTP study included 2063 recipients. Intervention Site A exhibited greater implementation fidelity than intervention Site B. For Hispanic recipients at Site A, the likelihood of receiving LDKTs was significantly higher at postintervention compared with pre-intervention (odds ratio [OR] = 3.17 95% confidence interval [1.04, 9.63]), but not at the paired control Site C (OR = 1.02 [0.61, 1.71]). For Hispanic recipients at Site B, the likelihood of receiving an LDKT did not differ between pre- and postintervention (OR = 0.88 [0.40, 1.94]). The LDKT rate was significantly lower for Hispanics at paired control Site D (OR = 0.45 [0.28, 0.90]). The intervention significantly improved LDKT rates for Hispanic patients at the intervention site that implemented the intervention with greater fidelity. Registration: ClinicalTrials.gov registered (retrospectively) on September 7, 2017 (NCT03276390).

RESUMEN

BACKGROUND & AIMS: The concept of benchmarking is established in the field of transplant surgery; however, benchmark values for donation after circulatory death (DCD) liver transplantation are not available. Thus, we aimed to identify the best possible outcomes in DCD liver transplantation and to propose outcome reference values. METHODS: Based on 2,219 controlled DCD liver transplantations, collected from 17 centres in North America and Europe, we identified 1,012 low-risk, primary, adult liver transplantations with a laboratory MELD score of ≤20 points, receiving a DCD liver with a total donor warm ischemia time of ≤30 minutes and asystolic donor warm ischemia time of ≤15 minutes. Clinically relevant outcomes were selected and complications were reported according to the Clavien-Dindo-Grading and the comprehensive complication index (CCI). Corresponding benchmark cut-offs were based on median values of each centre, where the 75th-percentile was considered. RESULTS: Benchmark cases represented between 19.7% and 75% of DCD transplantations in participating centres. The 1-year retransplant and mortality rates were 4.5% and 8.4% in the benchmark group, respectively. Within the first year of follow-up, 51.1% of recipients developed at least 1 major complication (≥Clavien-Dindo-Grade III). Benchmark cut-offs were ≤3 days and ≤16 days for ICU and hospital stay, ≤66% for severe recipient complications (≥Grade III), ≤16.8% for ischemic cholangiopathy, and ≤38.9 CCI points 1 year after transplant. Comparisons with higher risk groups showed more complications and impaired graft survival outside the benchmark cut-offs. Organ perfusion techniques reduced the complications to values below benchmark cut-offs, despite higher graft risk. CONCLUSIONS: Despite excellent 1-year survival, morbidity in benchmark cases remains high. Benchmark cut-offs targeting morbidity parameters offer a valid tool to assess the protective value of new preservation technologies in higher risk groups and to provide a valid comparator cohort for future clinical trials. LAY SUMMARY: The best possible outcomes after liver transplantation of grafts donated after circulatory death (DCD) were defined using the concept of benchmarking. These were based on 2,219 liver transplantations following controlled DCD donation in 17 centres worldwide. Donor and recipient combinations with higher risk had significantly worse outcomes. However, the use of novel organ perfusion technology helped high-risk patients achieve similar outcomes as the benchmark cohort.

RESUMEN

BACKGROUND AND AIMS: Radioembolization (yttrium-90 [Y90]) is used in hepatocellular carcinoma (HCC) as a bridging as well as downstaging liver-directed therapy to curative liver transplantation (LT). In this study, we report long-term outcomes of LT for patients with HCC who were bridged/downstaged by Y90. APPROACH AND RESULTS: Patients undergoing LT following Y90 between 2004 and 2018 were included, with staging by United Network for Organ Sharing (UNOS) tumor-node-metastasis criteria at baseline pre-Y90 and pre-LT. Post-Y90 toxicities were recorded. Histopathological data of HCC at explant were recorded. Long-term outcomes, including overall survival (OS), recurrence-free survival (RFS), disease-specific mortality (DSM), and time-to-recurrence, were reported. Time-to-endpoint analyses were estimated using Kaplan-Meier. Univariate and multivariate analyses were performed using a log-rank test and Cox proportional-hazards model, respectively. During the 15-year period, 207 patients underwent LT after Y90. OS from LT was 12.5 years, with a median time to LT of 7.5 months [interquartile range, 4.4-10.3]. A total of 169 patients were bridged, whereas 38 were downstaged to LT. Respectively, 94 (45%), 60 (29%), and 53 (26%) patients showed complete, extensive, and partial tumor necrosis on histopathology. Three-year, 5-year, and 10-year OS rates were 84%, 77%, and 60%, respectively. Twenty-four patients developed recurrence, with a median RFS of 120 (95% confidence interval, 69-150) months. DSM at 3, 5, and 10 years was 6%, 11%, and 16%, respectively. There were no differences in OS/RFS for patients who were bridged or downstaged. RFS was higher in patients with complete/extensive versus partial tumor necrosis (P < 0.0001). For patients with UNOS T2 treated during the study period, 5.2% dropped out because of disease progression. CONCLUSIONS: Y90 is an effective treatment for HCC in the setting of bridging/downstaging to LT. Patients who achieved extensive or complete necrosis had better RFS, supporting the practice of neoadjuvant treatment before LT.

RESUMEN

PURPOSE: To evaluate the outcomes of splenic artery aneurysm (SAA) embolization and compare adverse event (AE) rates after embolization in patients with and without portal hypertension (PHTN). MATERIALS AND METHODS: A retrospective review of all patients who underwent embolization of SAAs at 2 institutions was performed (34 patients from institution 1 and 7 patients from institution 2). Baseline demographic characteristics, preprocedural imaging, procedural techniques, and postprocedural outcomes were evaluated. Thirty-day postprocedural severe and life-threatening AEs were evaluated using the Society of Interventional Radiology guidelines. Thirty-day mortality and readmission rates were also evaluated. t test, χ2 test, and/or Fisher exact test were used for the statistical analysis. RESULTS: There was no statistically significant difference between patients with and without PHTN in the location, number, and size of SAA(s). All procedures were technically successful. There were 13 (32%) patients with and 28 (68%) patients without PHTN. The 30-day mortality rate (31% vs 0%; P = .007), readmission rates (61% vs 7%; P < .001), and severe/life-threatening AE rates (69% vs 0%; P < .001) were significantly higher in patients with PHTN than in those without PHTN. CONCLUSIONS: There was a significantly higher mortality and severe/life-threatening AE rate in patients with PHTN than in those without PHTN. SAAs in patients with PHTN need to be managed very cautiously, given the risk of severe/life-threatening AEs after embolization.

RESUMEN

BACKGROUND & AIMS: Pre-treatment Tc-99m macroaggregated albumin (MAA) scans are routinely performed prior to transarterial radioembolization (TARE) to estimate lung shunt fraction (LSF) and lung dose. In this study, we investigate LSF observed in early hepatocellular carcinoma (HCC) and provide the scientific rationale for eliminating this step from routine practice. METHODS: Patients with HCC who underwent Y90 from 2004 to 2018 were reviewed. Inclusion criteria were early stage HCC (UNOS T1/T2/Milan criteria: solitary ≤5 cm, 3 nodules ≤3 cm). LSF was determined using MAA in all patients. Associations between LSF and baseline characteristics were investigated. A "no-MAA" paradigm was then proposed based on a homogenous group that expressed very low LSF. RESULTS: Of 1,175 patients with HCC treated with TARE, 448 patients met inclusion criteria. Mean age was 65.6 years and 303 (68%) were males. A total of 352 (79%) had solitary lesions and 406 (91%) unilobar disease. Two-hundred and forty-three (54%), 178 (40%) and 27 (6%) patients were Child-Pugh class A, B and C, respectively. Median LSF was 3.9% (IQR 2.4-6%). Median administered activity was 0.9 GBq (IQR 0.6-1.4), for a median segmental volume of 170 cm3 (range: 60-530). Median lung dose was 1.9 Gy (IQR: 1.0-3.3). The presence of a transjugular intrahepatic portosystemic shunt (TIPS; n = 38) was associated with LSF >10% (odds ratio 12.2; 95% CI 5.2-28.6; p <0.001). Median LSF was 3.8% (IQR: 2.4-5.7%) and 6% (IQR: 3.8-15.3%) in no-TIPS vs. TIPS patients (p <0.001). CONCLUSION: LSF is clinically negligible in patients with UNOS T1/T2 HCC without TIPS. When segmental injections are planned, this step can be eliminated, thereby reducing time-to-treatment, number of procedures, and improving convenience for patients traveling from faraway. LAY SUMMARY: Transarterial radioembolization is a microembolic transarterial treatment for hepatocellular carcinoma. In our study, we found that early stage patients, where segmental injections are planned, exhibited low lung shunting, effectively eliminating the risk of radiation pneumonitis. We propose that the lung shunt study be eliminated in this subgroup, thus leading to fewer procedures, a cost reduction and improved convenience for patients.

RESUMEN

PURPOSE: The purpose of this study was to present the institutional experience of performing endoscopy, cholangiography, and biliary interventions through the modified Hutson loop by interventional radiology. MATERIALS AND METHODS: A total of 61 of 64 modified Hutson loop access procedures were successful. This single-center retrospective study included 61 successful procedures of biliary interventions using existing modified Hutson loops (surgically affixed subcutaneous jejunal limb adjacent to biliary anastomosis or anastomoses) for diagnostic or therapeutic purposes in 21 patients. Seventeen of 21 patients (81%) had undergone liver transplantation. Indications included biliary strictures (n = 18) and biliary leaks (n = 3). The clinical success and complications were evaluated. RESULTS: There were 3 of 26 modified Hutson loop retrograde biliary intervention failures (12%) before introduction of endoscopy and no failures (0 of 38 [0%]) subsequently (P = .06). Endoscopy or cholangioscopy was performed in 19 procedures by interventional radiologists. Retrograde biliary interventions included diagnostic cholangiography (n = 26), cholangioplasty (n = 25), stent placement (n = 29), stent retrieval (n = 25), and biliary drainage catheter placement (n = 5). No procedure-related mortality occurred. There was 1 major complication (duodenal perforation) (1.6%) and 12 minor complications (19%). In the 9 patients undergoing therapeutic interventions for biliary strictures, there was a significant decrease in median alkaline phosphatase (288.5 to 174.5 U/L; P = .03). There was a trend toward decrease in median bilirubin levels (1.7 to 1 mg/dL; P = .06) at 1 month post-intervention. CONCLUSIONS: The modified Hutson loop provided interventional radiologists a safe and effective alternative access to manage biliary complications in patients with biliary-enteric anastomoses. Introduction of the endoscope in interventional radiology has improved the success rate of these procedures.

RESUMEN

PURPOSE: Living donor kidney transplant (LDKT) imparts the best graft and patient survival for most end-stage kidney disease (ESKD) patients. Yet, there remains variation in post-LDKT health-related quality of life (HRQOL). Improved understanding of post-LDKT HRQOL can help identify patients for interventions to maximize the benefit of LDKT. METHODS: For 477 LDKT recipients transplanted between 11/2007 and 08/2016, we assessed physical, mental, social, and kidney-targeted HRQOL pre-LDKT, as well as 3 and 12 months post-operatively using the SF-36, Kidney Disease Quality of Life-Short Form (KDQOL-SF), and the Functional Assessment of Cancer Therapy-Kidney Symptom Index 19 item version (FKSI-19). We then examined trajectories of each HRQOL domain using latent growth curve models (LGCMs). We also examined associations between decline in HRQOL from 3 months to 12 months post-LDKT and death censored graft failure (DCGF) using Cox regression. RESULTS: Large magnitude effects (d > 0.80) were observed from pre- to post-LDKT change on the SF-36 Vitality scale (d = 0.81) and the KDQOL-SF Burden of Kidney Disease (d = 1.05). Older age and smaller pre- to post-LDKT decreases in serum creatinine were associated with smaller improvements on many HRQOL scales across all domains in LGCMs. Higher DCGF rates were associated with worse physical [e.g., SF-36 PCSoblique hazard ratio (HR) 1.18; 95% CI 1.01-1.38], mental (KDQOL-SF Cognitive Function HR 1.27; 95% CI 1.00-1.62), and kidney-targeted (FKSI-19 HR: 1.18; 95% CI 1.00-1.38) HRQOL domains. CONCLUSION: Clinical HRQOL monitoring may help identify patients who are most likely to have failing grafts and who would benefit from post-LDKT intervention.

RESUMEN

BACKGROUND: Despite available evidence-based interventions that decrease health disparities, these interventions are often not implemented. Northwestern Medicine's® Hispanic Kidney Transplant Program (HKTP) is a culturally and linguistically competent intervention designed to reduce disparities in living donor kidney transplantation (LDKT) among Hispanics/Latinos. The HKTP was introduced in two transplant programs in 2016 to evaluate its effectiveness. OBJECTIVE: This study assessed barriers and facilitators to HKTP implementation preparation. METHODS: Interviews and group discussions were conducted with transplant stakeholders (ie administrators, nurses, physicians) during implementation preparation. The Consolidated Framework for Implementation Research (CFIR) guided interview design and qualitative analysis. RESULTS: Forty-four stakeholders participated in 24 interviews and/or 27 group discussions. New factors, not found in previous implementation preparation research in health-care settings, emerged as facilitators and barriers to the implementation of culturally competent care. Implementation facilitators included: stakeholders' focus on a moral imperative to implement the HKTP, personal motivations related to their Hispanic heritage, and perceptions of Hispanic patients' transplant education needs. Implementation barriers included: stakeholders' perceptions that Hispanics' health insurance payer mix would negatively impact revenue, a lack of knowledge about LDKT disparities and patient data disaggregated by ethnicity/race, and a perception that the family discussion component was immoral because of the possibility of coercion. DISCUSSION AND CONCLUSIONS: Our study identified novel barriers and facilitators to the implementation preparation of a culturally competent care intervention. Healthcare administrators can facilitate organizations' implementation of culturally competent care interventions by understanding factors challenging care delivery processes and raising clinical team awareness of disparities in LDKT.

RESUMEN

Disproportionately fewer waitlisted Hispanics receive living donor kidney transplants (LDKTs) compared to non-Hispanic whites. Northwestern Medicine's® culturally targeted Hispanic Kidney Transplant Program (HKTP) is associated with a significant increase in LDKTs among Hispanics. This multisite study assessed potential kidney recipients' and donors' and/or family members' perceptions of the HKTP's cultural components through semi-structured interviews and validated surveys. Qualitative thematic analysis and descriptive statistics were performed. Thirty-six individuals participated (62% participation rate) comprising 21 potential recipients and 15 potential donors/family (mean age: 51 years, 50% female, 72% preferred Spanish). Participants felt confident about the educational information because a transplant physician delivered the education and viewed the group format as effective. Participants felt that education sessions addressed myths about transplantation shared by Hispanics. Primary use of Spanish enhanced participants' understanding of transplantation. While few knew about living donation before attending the HKTP, most were "more in favor of" kidney transplantation (97%) and living donation (97%) afterward. Few reported learning about the HKTP from outreach staff and suggested leveraging community leaders to promote HKTP awareness. Our findings suggest the HKTP's cultural components were viewed favorably and positively influenced perceptions of kidney transplantation and living donation, which may help reduce transplant disparities in Hispanics.

RESUMEN

Blood group B candidates, many of whom represent ethnic minorities, have historically had diminished access to deceased donor kidney transplantation (DDKT). The new national kidney allocation system (KAS) preferentially allocates blood group A2/A2B deceased donor kidneys to B recipients to address this ethnic and blood group disparity. No study has yet examined the impact of KAS on A2 incompatible (A2i) DDKT for blood group B recipients overall or among minorities. A case-control study of adult blood group B DDKT recipients from 2013 to 2017 was performed, as reported to the Scientific Registry of Transplant Recipients. Cases were defined as recipients of A2/A2B kidneys, whereas controls were all remaining recipients of non-A2/A2B kidneys. A2i DDKT trends were compared from the pre-KAS (1/1/2013-12/3/2014) to the post-KAS period (12/4/2014-2/28/2017) using multivariable logistic regression. Post-KAS, there was a 4.9-fold increase in the likelihood of A2i DDKT, compared to the pre-KAS period (odds ratio [OR] 4.92, 95% confidence interval [CI] 3.67-6.60). However, compared to whites, there was no difference in the likelihood of A2i DDKT among minorities post-KAS. Although KAS resulted in increasing A2/A2B→B DDKT, the likelihood of A2i DDKT among minorities, relative to whites, was not improved. Further discussion regarding A2/A2B→B policy revisions aiming to improve DDKT access for minorities is warranted.

RESUMEN

Purpose To report long-term outcomes of radiation segmentectomy (RS) for early hepatocellular carcinoma (HCC). The authors hypothesized that outcomes are comparable to curative treatments for patients with solitary HCC less than or equal to 5 cm and preserved liver function. Materials and Methods This retrospective study included 70 patients (median age, 71 years; range, 22-96 years) with solitary HCC less than or equal to 5 cm not amenable to percutaneous ablation who underwent RS (dose of >190 Gy) between 2003 and 2016. Patients who underwent subsequent curative liver transplantation were excluded to eliminate this confounding variable affecting survival. Radiologic response of time to progression and median overall survival were estimated by using the Kaplan-Meier method per the guidelines of the European Association for the Study of the Liver (EASL) and the World Health Organization (WHO). Results Seventy patients were treated with RS over 14 years. Sixty-three patients (90%) showed response by using EASL criteria, of which 41 (59%) showed complete response. Fifty patients (71%) achieved response by using WHO criteria, of which 11 (16%) achieved complete response. Response rates at 6 months were 86% and 49% by using EASL and WHO criteria, respectively. Median time to progression was 2.4 years (95% confidence interval: 2.1, 5.7), with 72% of patients having no target lesion progression at 5 years. Median overall survival was 6.7 years (95% confidence interval: 3.1, 6.7); survival probability at 1, 3, and 5 years was 98%, 66%, and 57%, respectively. Overall survival probability at 1, 3, and 5 years was 100%, 82%, and 75%, respectively, in patients with baseline tumor size less than or equal to 3 cm (n = 45) and was significantly longer than in patients with tumors greater than 3 cm (P = .026). Conclusion RS provides response rates, tumor control, and survival outcomes comparable to curative-intent treatments for selected patients with early-stage HCC who have preserved liver function. © RSNA, 2018 Online supplemental material is available for this article.

RESUMEN

BACKGROUND: The shortage of organs for kidney transplantation for patients with end-stage renal disease (ESRD) is magnified in Hispanics/Latin Americans in the United States. Living donor kidney transplantation (LDKT) is the treatment of choice for ESRD. However, compared to their representation on the transplant waitlist, fewer Hispanics receive a LDKT than non-Hispanic whites. Barriers to LDKT for Hispanics include: lack of knowledge, cultural concerns, and language barriers. Few interventions have been designed to reduce LDKT disparities. This study aims to reduce Hispanic disparities in LDKT through a culturally targeted intervention. METHODS/DESIGN: Using a prospective effectiveness-implementation hybrid design involving pre-post intervention evaluation with matched controls, we will implement a complex culturally targeted intervention at two transplant centers in Dallas, TX and Phoenix, AZ. The goal of the study is to evaluate the effect of Northwestern Medicine's® Hispanic Kidney Transplant Program's (HKTP) key culturally targeted components (outreach, communication, education) on Hispanic LDKT rates over five years. The main hypothesis is that exposure to the HKTP will reduce disparities by increasing the ratio of Hispanic to non-Hispanic white LDKTs and the number of Hispanic LDKTs. We will also examine other process and outcome measures including: dialysis patient outreach, education session attendance, marketing efforts, Hispanic patients added to the waitlist, Hispanic potential donors per potential recipient, and satisfaction with culturally competent care. We will use mixed methods based on the Promoting Action on Research Implementation in Health Services (revised PARIHS) and the Consolidated Framework for Implementation Research (CFIR) frameworks to formatively evaluate the fidelity and innovative adaptations to HKTP's components at both study sites, to identify moderating factors that most affect implementation fidelity, and to identify adaptations that positively and negatively affect outcomes for patients. DISCUSSION: Our study will provide new knowledge about implementing culturally targeted interventions and their impact on reducing health disparities. Moreover, the study of a complex organizational-level intervention's implementation over five years is rare in implementation science; as such, this study is poised to contribute new knowledge to the factors influencing how organizational-level interventions are sustained over time.

RESUMEN

PURPOSE: To assess safety/efficacy of yttrium-90 radioembolization (Y90) in patients with recurrent hepatocellular carcinoma (HCC) following curative surgical resection. METHODS: With IRB approval, we searched our prospectively acquired database for patients that were treated with Y90 for recurrent disease following resection. Baseline characteristics and bilirubin toxicities following Y90 were evaluated. Intention-to-treat overall survival (OS) and time-to-progression (TTP) from Y90 were assessed. RESULTS: Forty-one patients met study inclusion criteria. Twenty-six (63%) patients had undergone minor (≤3 hepatic segments) resection while 15 (37%) patients underwent major (>3 hepatic segments) resections. Two patients (5%) had biliary-enteric anastomoses created during surgical resection. The median time from HCC resection to the first radioembolization was 17 months (95% CI: 13-37). The median number of Y90 treatment sessions was 1 (range: 1-5). Ten patients received (entire remnant) lobar Y90 treatment while 31 patients received selective (≤2 hepatic segments) treatment. Grades 1/2/3/4 bilirubin toxicity were seen in nine (22%), four (10%), four (10%), and zero (0%) patients following Y90. No differences in bilirubin toxicities were identified when comparing lobar with selective approaches (P = 0.20). No post-Y90 infectious complications were identified. Median TTP and OS were 11.3 (CI: 6.5-15.5) and 22.1 months (CI: 10.3-31.3), respectively. CONCLUSIONS: Radioembolization is a safe and effective method for treating recurrent HCC following surgical resection, with prolonged TTP and promising survival outcomes.

RESUMEN

BACKGROUND: Hispanic dialysis patients often encounter barriers to learning about living kidney donation and transplantation. Effective culturally targeted interventions to increase knowledge are lacking. We developed a culturally targeted educational website to enhance informed treatment decision making for end-stage kidney disease. METHODS: A pretest/posttest intervention study was conducted among adult Hispanic patients undergoing dialysis at 5 dialysis centers in Chicago, Illinois. Surveys included a 31-item, multiple-choice pretest/posttest of knowledge about kidney transplantation and living donation, attitudes about the website, Internet use, and demographics. The intervention entailed viewing 3 of 6 website sections for a total of 30 minutes. The pretest/posttest was administered immediately before and after the intervention. Participants completed a second posttest via telephone 3 weeks thereafter to assess knowledge retention, attitudes, and use of the website. RESULTS: Sixty-three patients participated (96% participation rate). Website exposure was associated with a mean 17.1% same day knowledge score increase between pretest and posttest (P < .001). At 3 weeks, participants' knowledge scores remained 11.7% above pretest (P < .001). The greatest knowledge gain from pretest to 3-week follow-up occurred in the Treatment Options (P < .0001) and Cultural Beliefs and Myths (P < .0001) website sections. Most participants (95%) "agreed" or "strongly agreed" that they would recommend the website to other Hispanics. CONCLUSIONS: Web-based education for patients undergoing dialysis can effectively increase Hispanics' knowledge about transplantation and living kidney donation. Study limitations include small sample size and single geographic region study. Dialysis facilities could enable website access as a method of satisfying policy requirements to provide education about kidney transplantation.

RESUMEN

UNLABELLED: Resection and radiofrequency ablation (RFA) are treatment options for hepatocellular carcinoma (HCC) <3 cm; there is interest in expanding the role of ablation to 3-5 cm. RFA is considered high-risk when the lesion is in close proximity to critical structures. Combining microcatheter technology and the localized emission properties of Y90, highly selective radioembolization is a possible alternative to RFA in such cases. We assessed the efficacy (response, radiology-pathology correlation, survival) of radiation segmentectomy in solitary HCC not amenable to RFA or resection. Patients with treatment-naïve, unresectable, solitary HCC ≤ 5 cm not amenable to RFA were included in this multicenter study. Administered dose, response rate, time-to-progression (modified Response Evaluation Criteria in Solid Tumors [mRECIST]), radiology-pathology correlation and long-term survival were assessed. In all, 102 patients were included in this study. mRECIST complete response (CR), partial response (PR), and stable disease (SD) were 47/99 (47%), 39/99 (39%), and 12/99 (12%), respectively. Median time-to-disease-progression was 33.1 months. In all, 33/102 (32%) patients were transplanted with a median (interquartile range [IQR]) time-to-transplantation of 6.3 months (3.6-9.7). Pathology revealed 100% and 50-99% necrosis in 17/33 (52%) and 16/33 (48%), respectively. Median overall survival was 53.4 months. Univariate analysis demonstrated a survival benefit for Eastern Cooperative Oncology Group (ECOG) 0 patients. In the multivariate model, age <65, ECOG 0, and Child-Pugh A were characteristics associated with longer survival. CONCLUSION: Radiation segmentectomy is an effective technique with a favorable risk profile and radiology-pathology outcomes for solitary HCC ≤ 5 cm. This approach may allow for treatment of HCC in difficult locations. Since RFA and resection are not options given tumor location, there appears to be a strong rationale for this technique as second choice.

RESUMEN

CONTEXT: Hispanics receive disproportionately fewer live donor kidney transplants than non-Hispanic whites. Increasing Hispanics' knowledge and changing attitudes about live kidney donation may reduce these disparities. OBJECTIVE: To evaluate the effectiveness of culturally and linguistically competent educational sessions delivered through Northwestern University's Hispanic Transplant Program. DESIGN: Baseline and postsession questionnaires were used to evaluate changes in patients' and family members' knowledge and attitudes toward live kidney donation and program satisfaction. Knowledge items related to live kidney donation were scaled, and changes in scores were evaluated via a paired t test. Multiple regression analysis of follow-up knowledge scores controlled for baseline scores was used to estimate the effects of patients' and families' sociodemographic characteristics. Changes in attitude items, including comfort with exploring live kidney donation, were analyzed with χ2 tests. RESULTS: One-hundred thirteen patients and family members completed surveys before and after an education session. Respondents' knowledge about live kidney donation and transplant increased significantly (P<.001) between baseline and after the session. Patients' attitudes toward live kidney donation became more favorable (P< .02), as did family members' attitudes toward being a donor (P < .001) after participating in the program. All respondents reported high levels of satisfaction with the program and preferences for culturally congruent care. CONCLUSIONS: The educational sessions provided by the Hispanic Transplant Program effectively addressed commonly shared Hispanic concerns about live kidney donation. Culturally congruent education increased Hispanic patients' and family members' knowledge and improved attitudes about live donor kidney transplants.
