RESUMEN

PURPOSE: Salvage cystectomy is required for some patients with intravesical recurrence after trimodality therapy. We compared postoperative outcomes between salvage cystectomy post-trimodality therapy, primary cystectomy and primary cystectomy with prior history of nontrimodality therapy abdominal or pelvic radiotherapy. MATERIALS AND METHODS: We included 265 patients who underwent radical cystectomy at Massachusetts General Hospital for cT1-T4 bladder cancer between 2003 and 2013. Patients were grouped as salvage cystectomy post-trimodality therapy, primary cystectomy or primary cystectomy with prior history of nontrimodality therapy abdominal or pelvic radiotherapy. Early (≤90 days) and late (>90 days) complications were compared. Disease-specific survival and overall survival were calculated using a Cox regression model, and adjusted survival curves were generated. RESULTS: The median followup from the time of cystectomy was 65.5 months. There was no difference in intraoperative and early complications between the groups. The detection of late complications was higher in salvage cystectomy post-trimodality therapy compared to primary cystectomy and primary cystectomy with prior history of nontrimodality therapy abdominal or pelvic radiotherapy (p=0.03). In multivariable Cox regression analysis, salvage cystectomy post-trimodality therapy was associated with a higher incidence of any late (HR 2.3, p=0.02) and major late complications (HR 2.1, p <0.05). There was no difference in disease-specific survival (p=0.8) or overall survival (p=0.9) between the groups. CONCLUSIONS: Salvage cystectomy post-trimodality therapy for intravesical recurrence post-trimodality therapy has an intraoperative and early complication rate comparable to primary cystectomy and primary cystectomy with prior history of nontrimodality therapy abdominal or pelvic radiotherapy. Salvage cystectomy post-trimodality therapy is associated with a higher risk of overall and major late complications than primary cystectomy. The disease-specific survival and overall survival of patients who require salvage cystectomy post-trimodality therapy are comparable to both groups.

RESUMEN

OBJECTIVES: To develop and validate the Preoperative Risk Evaluation for Partial Nephrectomy (PREP) score to predict the probability of major postoperative complications after partial nephrectomy (PN) based on patient comorbidities. PATIENTS AND METHODS: The Premier Healthcare Database was used to identify patients who had undergone elective PN. Through review of International Classification of Diseases ninth revision codes, we identified patient comorbidities and major surgical complications (Clavien-Dindo Grade III-V). Multivariable logistic regression was used to identify predictors of major complications. We used half of the set as the training cohort to develop our risk score and the other half as a validation cohort. RESULTS: From 2003 to 2015, 25 451 PNs were performed. The overall rate of major complications was 4.9%. The final risk score consisted of 10 predictors: age, sex, congestive heart failure, coronary artery disease, chronic obstructive pulmonary disease, chronic kidney disease, diabetes, hypertension, obesity, and smoking. In the training cohort, the area under the receiver operating characteristic curve (AUC) was 0.75 (95% confidence interval [CI] 0.73-0.78), while the AUC for the validation cohort was 0.73 (95% CI 0.70-0.75). The predicted probabilities of major complication in the low- (≤10 points), intermediate- (11-20 points), high- (21-30 points), and very high-risk (>30 points) categories were 3% (95% CI 2.6-3.2), 8% (95% CI 7.2-9.2), 24% (95% CI 20.5-27.8), and 41% (95% CI 34.5-47.8), respectively. CONCLUSIONS: We developed and validated the PREP score to predict the risk of complications after PN based on patient characteristics. Calculation of the PREP score can help providers select treatment options for patients with a cT1a renal mass and enhance the informed consent process for patients planning to undergo PN.

RESUMEN

Cytotoxic chemotherapy is effective in debulking tumour masses initially; however, in some patients tumours become progressively unresponsive after multiple treatment cycles. Previous studies have demonstrated that cancer stem cells (CSCs) are selectively enriched after chemotherapy through enhanced survival. Here we reveal a new mechanism by which bladder CSCs actively contribute to therapeutic resistance via an unexpected proliferative response to repopulate residual tumours between chemotherapy cycles, using human bladder cancer xenografts. Further analyses demonstrate the recruitment of a quiescent label-retaining pool of CSCs into cell division in response to chemotherapy-induced damages, similar to mobilization of normal stem cells during wound repair. While chemotherapy effectively induces apoptosis, associated prostaglandin E2 (PGE2) release paradoxically promotes neighbouring CSC repopulation. This repopulation can be abrogated by a PGE2-neutralizing antibody and celecoxib drug-mediated blockade of PGE2 signalling. In vivo administration of the cyclooxygenase-2 (COX2) inhibitor celecoxib effectively abolishes a PGE2- and COX2-mediated wound response gene signature, and attenuates progressive manifestation of chemoresistance in xenograft tumours, including primary xenografts derived from a patient who was resistant to chemotherapy. Collectively, these findings uncover a new underlying mechanism that models the progressive development of clinical chemoresistance, and implicate an adjunctive therapy to enhance chemotherapeutic response of bladder urothelial carcinomas by abrogating early tumour repopulation.

RESUMEN

Acquired hydronephrosis following cystectomy and ileal conduit urinary diversion for bladder cancer is most commonly caused by stricture of the ureter or the ureteroenteric anastomosis. Nevertheless, malignant obstruction due to ureteral tumor recurrence must be ruled out. Neuroendocrine tumors of the ureter are extremely rare and an unlikely cause of hydronephrosis in this setting. We present the first reported case of a patient with a history of bladder cancer and an ileal conduit presenting with hydronephrosis secondary to an obstructing carcinoid tumor of the ureter.

RESUMEN

INTRODUCTION: Placement of coudé catheters, manual irrigation of urinary catheters, and management of continuous bladder irrigation (CBI) are routine interventions for which nurses often receive little or no formal education. In this study, our aim was to determine factors associated with higher comfort levels for these catheter-care techniques and to assess whether online instructional videos could be used to improve nursing comfort. MATERIALS AND METHODS: Three 5-minute videos were created to demonstrate proper technique for coudé catheter placement, manual irrigation of a catheter, and management of CBI. An online module with pre- and post-video surveys was created and administered to all nursing staff at MedStar Georgetown University Hospital. RESULTS: A total of 821 nurses participated in this study and completed the online module with both pre-- and post-video surveys. Using a 10-point Likert scale, pre-video median comfort levels for coudé catheter placement, manual irrigation of a catheter, and management of CBI were 5, 6, and 5, respectively. Post-video median comfort levels increased significantly to 9, 8, and 8, respectively (p < 0.001). In the linear regression models, prior formal training was significantly associated with higher baseline comfort levels for all three techniques (p < 0.001). CONCLUSIONS: Prior formal training as well as baseline nursing comfort levels for common catheter related techniques tend to be low and the implementation of simple instructional videos via an online platform may be a useful strategy for improving nursing comfort. This study demonstrates a reproducible strategy for disseminating catheter education for nurses on a larger scale.

RESUMEN

INTRODUCTION Surgical trainees experience high rates of depression and suicidal ideation (SI). However, there remain a gap in knowledge on the drivers of depression and SI in trainees, especially within the field of urology. MATERIALS AND METHODS: We conducted a national study of urology trainees using a 50-item questionnaire in May 2018. The survey included demographic, depression (Patient Health Questionnaire-9 (PHQ-9)), burnout (Maslach Burnout Inventory (MBI)), and quality of life (QoL) questions. RESULTS: Overall, 37 (17.6%) endorsed depression; 24 residents endorsed SI (11%). SI was higher in those with depression (p < 0.001). Burnout was also higher among depressed residents (97.3% versus 61.8%, p < 0.001) and those endorsing SI (16.1% versus 1.5%, p < 0.001). Depression was associated with female gender (29.2% versus 12.4%, p = 0.005), fatigue (29.5% versus 7.8%, p < 0.001), and lack of structured mentorship (23.7% versus 9.8%, p = 0.010). Access to mental health services was protective (p = 0.016). Older age, low QoL, dissatisfaction with work-life-balance (WLB), and fatigue were associated with SI. On adjusted analysis, gender (OR 3.1 [95%CI 1.4-6.9], p = 0.006), fatigue (OR 3.8[95%CI 1.6-9.0], p = 0.002), and burnout (OR 16.7 [95%CI 2.2-127.5], p = 0.007) increased the odds of depression. On exploratory analysis, self-reported burnout alone was predictive of SI (OR 7.6 [95%CI 2.5-23]), and performed similarly to an adjusted model (AUC Area 0.718 [95%CI 0.634-0.802] versus 0.825 [0.753-0.897]). CONCLUSIONS: Urology trainees experience high rates of depression and SI. Female residents have significantly higher risk of depression. A single-item appears useful to screen for SI. Further investigation is needed to understand and promote urology resident wellness.

RESUMEN

OBJECTIVE: To examine the incidence of perioperative complications after radical cystectomy (RC) and assess their impact on 90-day postoperative mortality during the index stay and upon readmission. PATIENTS AND METHODS: A total of 57 553 patients with bladder cancer (unweighted cohort: 9137 patients) treated with RC, at 360 hospitals in the USA between 2005 and 2013 within the Premier Healthcare Database, were used for analysis. The 90-day perioperative mortality was the primary outcome. Multivariable regression was used to predict the probability of mortality; models were adjusted for patient, hospital, and surgical characteristics. RESULTS: An increase in the number of complications resulted in an increasing predicted probability of mortality, with a precipitous increase if patients had four or more complications compared to one complication during hospitalisation following RC (index stay; 1.0-9.7%, P < 0.001) and during readmission (2.0-13.1%, P < 0.001). A readmission complication nearly doubled the predicted probability of postoperative mortality as compared to an initial complication (3.9% vs 7.4%, P < 0.001). During the initial hospitalisation cardiac- (odds ratio [OR] 3.1, 95% confidence interval [CI] 1.9-5.1), pulmonary- (OR 4.8, 95% CI 2.8-8.4), and renal-related (OR 3.6, 95% CI 2-6.7) complications had the most significant impact on the odds of mortality across categories examined. CONCLUSIONS: The number and nature of complications have a distinct impact on mortality after RC. As complications increase there is an associated increase in perioperative mortality.

RESUMEN

OBJECTIVE: To describe the prevalence and predictors of burnout in USA and European urology residents, as although the rate of burnout in urologists is high and associated with severe negative sequelae, the extent and predictors of burnout in urology trainees remains poorly understood. SUBJECTS AND METHODS: An anonymous 32-question survey of urology trainees across the USA and four European countries, analysing personal, programme, and institutional factors, was conducted. Burnout was assessed using the validated abridged Maslach Burnout Inventory. Univariate analysis and multivariable logistic regression models assessed drivers of burnout in the two cohorts. RESULTS: Overall, 40% of participants met the criteria for burnout as follows: Portugal (68%), Italy (49%), USA (38%), Belgium (36%), and France (26%). Response rates were: USA, 20.9%; Italy, 45.2%; Portugal, 30.5%; France, 12.5%; and Belgium, 9.4%. Burnout was not associated with gender or level of training. In both cohorts, work-life balance (WLB) dissatisfaction was associated with increased burnout (odds ratio [OR] 4.5, P < 0.001), whilst non-medical reading (OR 0.6, P = 0.001) and structured mentorship (OR 0.4, P = 0.002) were associated with decreased burnout risk. Lack of access to mental health services was associated with burnout in the USA only (OR 3.5, P = 0.006), whilst more weekends on-call was associated with burnout in Europe only (OR 8.3, P = 0.033). In both cohorts, burned out residents were more likely to not choose a career in urology again (USA 54% vs 19%, P < 0.001; Europe 43% vs 25%, P = 0.047). CONCLUSION: In this study of USA and European urology residents, we found high rates of burnout on both continents. Despite regional differences in the predictors of burnout, awareness of the unique institutional drivers may help inform directions of future interventions.

RESUMEN

OBJECTIVE: To quantify the financial impact of complications after radical cystectomy (RC) and their associations with respective 90-day costs, as RC is a morbid surgery plagued by complications and the expenditure attributed to specific complications after RC is not well characterised. PATIENTS AND METHODS: We used the Premier Hospital Database (Premier Inc., Charlotte, NC, USA) to identify 9 137 RC patients (weighted population of 57 553) from 360 hospitals between 2003 and 2013. Complications were categorised according to Agency for Healthcare Research and Quality Clinical Classifications. Patients with and without complications were compared, and multivariable analysis was performed. RESULTS: An index complication increased costs by $9 262 (95% confidence interval [CI] 8 300-10 223) and a readmission complication increased costs by $20 697 (95% CI 18 735-22 660). The four most costly index complications (descending order) were venous thromboembolism (VTE), infection, wound and soft tissue complications, and pulmonary complications (P < 0.001, vs no complication). A complication increased length of stay by 4 days (95% CI 3.6-4.3). One in five patients were readmitted in 90 days and the four costliest readmission complications (descending order) were pulmonary, bleeding, VTE, and gastrointestinal complications (P < 0.001, vs no complication). Readmitted patients had multiple complications upon readmission (median of 3, interquartile range 2-4). On multivariable analysis, more comorbidities, longer surgery (>6 h), transfusions of >3 units, and teaching hospitals were associated with higher costs (P < 0.05), whilst high-volume surgeons and shorter surgeries (<4 h) were associated with lower costs (P < 0.05). CONCLUSIONS: Complications after RC increase index and readmission costs for hospitals, and can be categorised based on magnitude. Future initiatives in RC may also consider costs of complications when establishing quality improvement priorities for patients, providers, or policymakers.

RESUMEN

PURPOSE: Infectious, wound and soft tissue events contribute to the morbidity of radical cystectomy but the association between these events and antibiotic prophylaxis is not clear. We sought to describe the contemporary use of antibiotic prophylaxis in radical cystectomy and adherence to published guidelines, and identify regimens with the lowest rates of infectious events. MATERIALS AND METHODS: We identified the intraoperative antibiotic prophylaxis regimen in a population based, retrospective cohort study of patients who underwent radical cystectomy across the United States between 2003 and 2013. Multivariable regression was done to evaluate 90-day infectious events and length of stay. RESULTS: In a weighted cohort of 52,349 patients there were 579 unique antibiotic prophylaxis regimens. Cefazolin was the most commonly used antibiotic (16% of cases). The overall infectious event rate was 25%. Only 15% of patients received antibiotic prophylaxis based on guidelines. Of guideline based antibiotic prophylaxis ampicillin/sulbactam had the lowest odds of infectious events (OR 0.34, p <0.001). In 2.7% of patients a penicillin based regimen with a ß-lactamase inhibitor was associated with a prominent reduction in the odds of infectious events (OR 0.45, p = 0.001) and decreased length of stay (-1.3 days, p = 0.016). CONCLUSIONS: Antibiotic prophylaxis practices are highly heterogeneous in radical cystectomy. There is a lack of adherence to published guidelines. We observed decreased infectious event rates and shorter length of stay with regimens that included broad coverage of common skin, genitourinary and gastrointestinal flora. The ideal antibiotic regimen requires further study to optimize perioperative outcomes.

RESUMEN

Radical cystectomy (RC) is the gold standard treatment for patients with organ-confined bladder cancer. However, despite the success of this treatment, many men who undergo orthotopic neobladder substitution develop significant erectile dysfunction and urinary symptoms, including daytime and nighttime urinary incontinence. Prostate-capsule-sparing radical cystectomy (PCS-RC) with orthotopic neobladder (ONB) has been described in the literature as a surgical technique to improve functional outcomes in appropriately selected patients. We performed a systematic review and meta-analysis of manuscripts on PCS-RC with ONB published after 2000. We included retrospective and prospective studies with more than 25 patients and compared PCS-RC with nerve-sparing or conventional RC. Studies in which the entire prostate was spared (including the transitional zone) were excluded. Comparative studies were analyzed to assess rates of daytime continence, nighttime continence, and satisfactory erectile function in patients undergoing PCS-RC compared with those undergoing conventional RC. Fourteen reports were included in the final review. Our data identify high rates of daytime (83%-97%) and nighttime continence (60%-80%) in patients undergoing PCS-RC with ONB. In comparative studies, meta-analysis results demonstrate no difference in daytime continence (RR:1.12; 95% CI: 0.72-1.73) in those undergoing PCS-RC compared to those undergoing conventional RC. Similarly, nighttime continence was similar between the 2 groups (RR:1.85; 95% CI: 0.57-6.00. Erectile function was improved in those undergoing PCS-RC (RR 5.35; 95% CI: 1.82-15.74) in the PCS-RC series. Bladder cancer margin positivity and recurrence rates were similar to those reported in the literature with conventional RC with an average weighted follow-up of 52.2 months. While several studies utilized different prostate cancer (CaP) screening techniques, the rates of CaP were low (incidence 0.02; 95% CI:0.01-0.04), and oncologic outcomes were similar to standard RC. PCS-RC is associated with improved nighttime continence and erectile function compared to conventional RC techniques. Further work is needed to standardize CaP screening before surgery, but the data suggest low rates of CaP with similar oncologic outcomes when compared to RC.

RESUMEN

INTRODUCTION: Lower extremity lymphedema is a major source of morbidity in up to 70% of penile cancer patients. Lymphedema is often thought to be incurable, though surgical treatments have started to emerge. This study is the first to apply lymphovenous bypass specifically to penile cancer patients status post lymphadenectomy. METHODS: We performed microsurgical lymphovenous bypass in 3 patients who underwent inguinal lymphadenectomy for advanced penile cancer, and later lymph node transplant in 1 patient. RESULTS: The lymphovenous bypass was performed by a trained microsurgeon: Two patients were treated as outpatients for lymphedema, and 1 patient underwent prophylactic lymphovenous bypass simultaneously with initial lymphadenectomy. We saw significant improvement in patient's clinical lymphedema as well as lymphatic drainage on infared imaging for 2 of 3 patients at 12 months, however 1 of these patients did require later lymph node transfer at 24 months. CONCLUSION: This early proof of concept study shows that these procedures should be considered and studied further in the treatment and prevention of debilitating lymphedema in the penile cancer population.

RESUMEN

OBJECTIVE: To identify racial and sex disparities in the treatment and outcomes of muscle-invasive bladder cancer (MIBC) using a nationwide oncology outcomes database. METHODS: Using the National Cancer Database, we identified patients with muscle invasive bladder cancer from 2004 to 2014. Treatments analyzed included no treatment, cystectomy, neoadjuvant chemotherapy plus cystectomy ("optimal treatment"), cystectomy plus adjuvant chemotherapy, and chemoradiation. Propensity matching compared mortality outcomes between sexes. Logistic models evaluated predictors of receiving optimal treatment, as well as mortality. RESULTS: Forty seven thousand two hundred and twenty nine patients were identified. Most patients were male (73.4%) and underwent cystectomy alone (69.0%). Propensity score matching demonstrated increased 90-day mortality in women vs men (13.0% vs 11.6%, P = .009), despite adjusting for differences in treatments between sexes. Logistic regression models showed no difference in receipt of optimal treatment between sexes (odds ratio [OR] 1.01, 95% confidence interval [CI] 0.83-1.22) although black patients were less likely to receive optimal treatment (OR 0.15, 95% CI 0.05-0.48). Logistic regression models confirmed increased 90-day mortality in female (OR 1.17, CI 1.08-1.27, P < .001) and black (OR 1.29, CI 1.11-1.50, P = .001) patients. Females had a lower overall survival on Cox regression analysis (Hazard Ratio 0.92, 95% CI 0.87-0.97). CONCLUSION: While there do not appear to be significant treatment disparities between sexes, women experience higher 90-day mortality and lower overall survival. Black patients are less likely to receive optimal treatment and have a higher risk of 90-day mortality. Additional research is needed to determine the variables leading to worse outcomes in females and identify impediments to black patients receiving optimal treatment.

RESUMEN

INTRODUCTION: Extended outpatient chemoprophylaxis (ECP) following radical cystectomy (RC) for bladder cancer is proven to reduce rates of venous thromboembolism (VTE). While ECP is commonly performed with enoxaparin, its cost-effectiveness and adherence rate has been called into question. Data from orthopedic literature suggest that ECP with direct oral anticoagulants (DOACs) may be as effective in VTE prevention as enoxaparin in patients undergoing joint surgery. Our goal is to determine how urologic oncologists employ ECP following RC. METHODS: Members of the Society of Urologic Oncology were surveyed on practice patterns for the use of ECP after RC. Specific questions were asked regarding the use of inpatient and outpatient VTE prophylaxis, as well as perceived barriers to DOACs and enoxaparin. RESULTS: There were 121 of 878 (13.8%) respondents and the majority were in academic practices (83%). Most respondents had at least 5 years of experience and performed greater than 10 cystectomies annually. Almost all participants utilized inpatient (97%) and extended (80%) chemoprophylaxis for VTE prevention. Of those who elected for ECP, almost all (96%) used enoxaparin. Only 3 respondents (3%) prescribed oral agents such as rivaroxaban (2) or warfarin (1). Among those using enoxaparin, financial-specific barriers to treatment such as lack of insurance coverage (38%), inability to afford the medication (51%), and need for additional insurance authorization (44%) were reported. Poor patient adherence and refusal to perform injections were reported by 20% and 18% of respondents, respectively. Among the 23 physicians who did not use ECP, cost (39%) and delivery method (26%) were cited as barriers to treatment. CONCLUSIONS: The majority of surveyed urologic oncologists are prescribing subcutaneous enoxaparin ECP following RC. Poor patient adherence due to self-injections and financial barriers were frequently reported and represent a possible opportunity for the use of oral anticoagulants in the post-operative setting. These data will be used in the development of a proposed clinical trial of a DOAC in the post-RC setting.

RESUMEN

OBJECTIVE: To evaluate the outcomes of men diagnosed with prostate cancer (CaP) following implanted treatments for advanced heart failure. Given the increasingly favorable 10-year life expectancy, MedStar Washington Hospital Center screens heart transplant (HT) candidates for CaP and other malignancies prior to intervention. METHODS: Men aged 18-90 with available pretransplant Prostate Specific Antigen (PSA) who underwent left ventricular assist device (LVAD) and/or HT at MedStar Washington Hospital Center from 2007 to 2018 were identified. Serum PSA, CaP diagnosis, and treatment were captured and analyzed. Survival was analyzed using Kaplan-Meier curves. RESULTS: Data were available for 34 patients. Median age was 53 [IQR = 51-58]. Median follow-up was 77 months (95% CI = 40-87 months). Six men had postimplant elevated PSA (5.3; SD = 8.5) and 4 were diagnosed with CaP. Median age of CaP diagnosis was 59 [IQR = 58.5-62). As of 2018, 31 of the 34 patients were living, and none died from CaP. Five-year survival was 96% in those without CaP and 100% in those with CaP (Figure 2). CONCLUSION: Our cohort represents the largest known cohort with heart failure treated by LVAD and/or HT and CaP. Our median age of 59 at CaP diagnosis is considerably younger than the national median of 66.1 Of the 4 individuals diagnosed with CaP, 3 had high-grade disease. Given the favorable long-term survival of these patients post-LVAD and/or HT, age-appropriate treatment for CaP should be continued postimplantation.

RESUMEN

Purpose: Cisplatin-based neoadjuvant chemotherapy (NAC) followed by radical cystectomy (RC) is standard of care for muscle-invasive bladder cancer (MIBC). However, NAC is used in less than 20% of patients with MIBC. Our goal is to investigate factors that contribute to underutilization NAC to facilitate more routine incorporation into clinical practice. Materials and Methods: We identified 5,915 patients diagnosed with cT2-T3N0M0 MIBC who underwent RC between 2004 and 2014 from the National Cancer Database. Univariate and multivariable models were created to identify variables associated with NAC utilization. Results: Only 18.8% of patients received NAC during the study period. On univariate analyses, NAC utilization was more likely at academic hospitals, US South and Midwest (p<0.05). Higher Charlson score was associated with decrease use of NAC (p<0.05). On multivariate analysis, treatment in academic hospitals (odds ratio [OR], 1.367; 95% confidence interval [CI], 1.186-1.576), in the Midwest (OR, 1.538; 95% CI, 1.268-1.977) and South (OR, 1.424; 95% CI, 1.139-1.781) were independently associated with NAC utilization. Older age (75 to 84 years old; OR, 0.532; 95% CI, 0.427-0.664) and higher Charlson score (OR, 0.607; 95% CI, 0.439-0.839) were associated with decreased NAC utilization. Sixty-eight percent of patients did not receive NAC because it was not planned and only 2.5% of patients had contraindications for NAC treatment. Conclusions: Our study demonstrates that NAC is underutilized. Decreased utilization of NAC was associated with older patients and higher Charlson score. This underutilization may be related to practice patterns as very few patients have true contraindications.

RESUMEN

Objectives: To examine the temporal association between blood transfusion and 90-day mortality in patients with bladder cancer treated with radical cystectomy.Methods: This represents a retrospective cohort study of patients treated with radical cystectomy within the Premier Hospital network between 2003 and 2015. Patients outcomes were stratified those who received early blood transfusion (day of surgery) vs delayed blood transfusion (postoperative day ≥1) during the index admission. Primary end point was 90-day mortality following surgery.Results: The median age of 12,056 patients identified was 70 years. A total of 7,201 (59.7%) patients received blood transfusion. Within 90 days following surgery, 57 (2.2%), 162 (5.9%) and 123 (6.7%) patients in the early, delayed and both early and delayed transfused patients died respectively. Following multivariate logistic regression to account for patient (age and Charlson Comorbidity Index [CCI]) and hospital (surgeon volume, surgical approach and academic status) factors, delayed blood transfusion was independently associated with 90-day mortality (Odds ratio [OR], 2.64; 95% Confidence Interval [CI], 1.98-3.53; p < 0.001). A sensitivity analysis defining early blood transfusion as <2 days postoperatively, increased 90-day mortality persisted in patients receiving delayed transfusion (OR, 2.20; 95% CI, 1.63-3.00; p < 0.001). Older patients (≥77 years) with the highest CCI (≥2) had a 7% absolute increase in the predicted probability of 90-day mortality if they were transfused late compared to patients transfused early.Conclusion: Patient undergoing cystectomy may benefit from expedited transfusion to prevent subsequent clinical deterioration which may lead to patient mortality. Future work is needed to elucidate the optimal timing of blood transfusion.

RESUMEN

OBJECTIVE: To examine the use of in-hospital pharmacologic thromboprophylaxis (PTP) in patients undergoing radical cystectomy between 2004 and 2014 and to assess the risk of venous thromboembolism (VTE) across the study period. MATERIAL AND METHODS: We identified 8322 patients without contraindications to PTP undergoing radical cystectomy in the US using the Premier Healthcare Database. Nonparametric Wilcoxon type test for trend was employed to examine the trend of PTP utilization across the study period. Ensuing, we employed multivariable logistic regression and generalized linear regression models to examine the odds of receiving PTP and the risk of being diagnosed with VTE, respectively. RESULTS: Based on VTE risk-stratification, the majority of patients (87.8%) qualified as "high-risk." Across the study period the use of PTP increased (Odds ratio 1.02, 95% confidence interval (CI) 1.00-1.03, P = .044), but remained underutilized as the maximum percentage of patients receiving in-hospital PTP did not exceed 58.6%. The risk of VTE did not vary across the study period (risk ratio 0.97, 95%CI 0.92-1.02, P = .178). CONCLUSION: Utilization of PTP increased throughout the study period, while the risk of VTE did not change. Future studies are necessary to improve implementation of guideline-driven care, as PTP remained underutilized throughout the study period.

RESUMEN

BACKGROUND: Clinician burnout in hospice and palliative care (HPC) has potentially widespread negative consequences including increased clinical errors, decreased professionalism, decreased staff retention, and decreased empathy. Reading non-medical literature has been associated with increased empathy, but no studies on the effect of reading on burnout have previously been conducted. We wished to assess reading patterns of practicing HPC clinicians and determine associations between non-medical reading and burnout. METHODS: Sixteen-item electronic survey regarding reading practices, exposure to non-medical literature, fatigue, quality of life, and burnout symptoms was administered to members of the American Academy of Hospice and Palliative Medicine. Burnout measures of emotional exhaustion and depersonalization were assessed by the validated 2-item Maslach Burnout Inventory. Data were analyzed using descriptive statistics and multivariate regression. RESULTS: Seven hundred nine members responded (15.2% response rate), of which 129 (18.2%) met the criteria for burnout, with 117 (16.6%) meeting the criteria for high emotional exhaustion and 45 (7.9%) meeting the criteria for high depersonalization. On univariate analysis, burnout was associated with age, reading habits, and fatigue, but not years in practice. On multivariable logistic regression consistent readers had decreased odds of overall burnout compared to inconsistent readers (OR 0.61; 95% CI, 0.39-0.97, P=0.036). This was true across the depersonalization (OR 0.58; 95% CI, 0.36-0.93, P=0.025), but not the emotional exhaustion domain. CONCLUSIONS: Reading non-medical literature on a consistent basis may be associated with a significantly decreased likelihood of burnout, specifically across the depersonalization domain.
