RESUMEN

INTRODUCTION: Rural populations routinely rank poorly on common health indicators. While it is understood that rural residents face barriers to health care, the exact nature of these barriers remains unclear. To further define these barriers, a qualitative study of primary care physicians practicing in rural communities was performed. METHODS: Semistructured interviews were conducted with primary care physicians practicing in rural areas within western Pennsylvania, the third largest rural population within the USA, using purposively sampling. Data were then transcribed, coded, and analyzed by thematic analysis. RESULTS: Three key themes emerged from the analysis addressing barriers to rural health care: (1) cost and insurance, (2) geographic dispersion, and (3) provider shortage and burnout. Providers mentioned strategies that they either employed or thought would be beneficial for their rural communities: (1) subsidize services, (2) establish mobile and satellite clinics (particularly for specialty care), (3) increase utilization of telehealth, (4) improve infrastructure for ancillary patient support (ie social work services), and (5) increase utilization of advanced practice providers. CONCLUSION: There are numerous barriers to providing rural communities with quality health care. Barriers that are encountered are multidimensional. Patients are unable to obtain the care they need because of cost-related barriers. More providers need to be recruited to rural areas to combat the shortage and burnout. Advanced care-delivery methods such as telehealth, satellite clinics, or advanced practice providers can help bridge the gaps caused by geographic dispersion. Policy efforts should target all these aspects in order to appropriately address rural healthcare needs.

RESUMEN

BACKGROUND: Surgeons play a pivotal role in combating the opioid crisis that currently grips the United States. Changing surgeon behavior is difficult, and the degree to which behavioral science can steer surgeons toward decreased opioid prescribing is unclear. METHODS: This was a single-institution, single-arm, pre- and postintervention study examining the prescribing of opioids by urologists for adult patients undergoing prostatectomy or nephrectomy. The primary outcome was the quantity of opioids prescribed in oral morphine equivalents (OMEs) after hospital discharge. The primary exposure was a multipronged behavioral intervention designed to decrease opioid prescribing. The intervention had 3 components: 1) formal education, 2) individual audit feedback, and 3) peer comparison performance feedback. There were 3 phases to the study: a pre-intervention phase, an intervention phase, and a washout phase. RESULTS: Three hundred eighty-two patients underwent prostatectomy, and 306 patients underwent nephrectomy. The median OMEs decreased from 195 to 19 in the prostatectomy patients and from 200 to 0 in the nephrectomy patients (P < .05 for both). The median OMEs prescribed did not increase during the washout phase. Prostatectomy patients discharged with opioids had higher levels of anxiety than patients discharged without opioids (P < .05). Otherwise, prostatectomy and nephrectomy patients discharged with and without opioids did not differ in their perception of postoperative pain management, activity levels, psychiatric symptoms, or somatic symptoms (P > .05 for all). CONCLUSIONS: Implementing a multipronged behavioral intervention significantly reduced opioid prescribing for patients undergoing prostatectomy or nephrectomy without compromising patient-reported outcomes.

RESUMEN

PURPOSE: Clinical trials serve as a critical source of information to guide evidence-based practices in urology. Conversely, trials that are abandoned consume significant resources and results are underreported in the literature. MATERIALS AND METHODS: ClinicalTrials.gov was queried for urology trials from 2006 to 2016. Trials were screened by 2 screeners for applicability to urology and disputes were resolved by a third independent reviewer. Overall 1,340 trials met final inclusion criteria (722 successful trials, 618 failed trials). Univariable analysis used Fisher's exact, chi-squared and Wilcoxon rank sum tests. Trial characteristics, including AUA (American Urological Association) section, phase, subspecialty, intervention type, source of funding and randomization were examined for association with failure using multivariable logistic regression. RESULTS: Trial failure is associated with oncology subspecialty (adjusted odds ratio 2.25, 95% CI 1.60-3.18), infertility/andrology subspecialty (AOR 4.99, CI 1.60-17.61), device trials (AOR 1.64, CI 1.00-2.70) and combination funding by industry/government/grants (AOR 3.13, CI 2.21-4.48). Clinical trials in AUA sections were less likely to fail than international and multisectional trials. Among trials that failed, poor accrual was the primary reason for trial failure, comprising 41% of all failures. Other reasons for failure include inadequate budget (9%), sponsor cancellation (7%), poor interim results (7%) and toxicity (3%). CONCLUSIONS: Despite their significance, many urological trials fail prematurely due to poor accrual. Complex features inherent to oncology, andrology/infertility, devices and multisectional trials pose significant barriers to success.

RESUMEN

PURPOSE: Compared to urban populations, rural populations rank poorly on numerous health indicators, including cancer outcomes. We examined the relationship of rural residence with stage and treatment among patients with prostate cancer, the second most common malignancy in men. MATERIALS AND METHODS: Using the Pennsylvania Cancer Registry we identified all men diagnosed with prostate cancer between 2009 and 2015. Patients were classified as residing in a rural area, a large town or an urban area using the Rural-Urban Commuting Area classification. Our primary outcomes included indicators of prostate cancer treatment and treatment types but we also examined disease stage and mortality. We used the chi-square tests to assess differences between groups and estimated multivariable logistic regression models to assess the association between rural residence and treatment. RESULTS: We identified 51,024 men diagnosed with localized or metastatic prostate cancer between 2009 and 2015. The overall incidence of prostate cancer decreased during the study period from 416 to 304/100,000 men while the incidence of metastatic disease increased from 336 to 538/100,000. Rural residents were less likely to undergo treatment than urban residents even when stratified by low, intermediate and high risk disease (aOR 0.77, 95% CI 0.64-0.91; aOR 0.71, 95% CI 0.58-0.89; and aOR 0.68, 95% CI 0.53-0.89, respectively). Rural status did not affect the receipt of radiation therapy compared to other treatment types. CONCLUSIONS: Prostate cancer treatment differs between urban and rural residents. Rural residents are less likely to receive treatment even when stratified by disease risk.

RESUMEN

OBJECTIVE: To examine factors associated with PET scan use in the pre-operative evaluation of patients diagnosed with bladder cancer. METHODS: Using SEER-Medicare data, we identified bladder cancer patients who underwent radical cystectomy from 2006 to 2011 (n = 4,138). The primary outcome was PET scan use within 6 months before surgery. To examine predictors of PET scan use, we fit a mixed logit model with health service area as a random effect to account for patients nested within health service areas. We also calculated the adjusted probability of use over time and examined variation among the highest volume surgeons. RESULTS: Among the 4,138 patients, 406 (10%) received a pre-operative PET scan. The adjusted probability of a patient undergoing a PET scan increased from 0.04 in 2004 to 0.10 in 2011 (p < .001). Among the 78 highest volume surgeons, there was significant variation in PET scan use (p < .001). Patients with non-urothelial histology, measurement of alkaline phosphatase levels, and receipt of neoadjuvant chemotherapy were more likely to receive PET scan (all p < .05). CONCLUSION: Use of PET prior to radical cystectomy doubled over a 5-year period, suggesting its increased use in patients with muscle-invasive bladder cancer, particularly those with high-risk disease. Whether its use is warranted and improves patient outcomes is not clear and requires further studies.

RESUMEN

BACKGROUND: We previously reported the presence of prostate-specific antigen (PSA) in the stromal compartment of benign prostatic hyperplasia (BPH). Since PSA is expressed exclusively by prostatic luminal epithelial cells, PSA in the BPH stroma suggests increased tissue permeability and the compromise of epithelial barrier integrity. E-cadherin, an important adherens junction component and tight junction regulator, is known to exhibit downregulation in BPH. These observations suggest that the prostate epithelial barrier is disrupted in BPH and E-cadherin downregulation may increase epithelial barrier permeability. METHODS: The ultra-structure of cellular junctions in BPH specimens was observed using transmission electron microscopy (TEM) and E-cadherin immunostaining analysis was performed on BPH and normal adjacent specimens from BPH patients. In vitro cell line studies using benign prostatic epithelial cell lines were performed to determine the impact of small interfering RNA knockdown of E-cadherin on transepithelial electrical resistance and diffusion of fluorescein isothiocyanate (FITC)-dextran in transwell assays. RESULTS: The number of kiss points in tight junctions was reduced in BPH epithelial cells as compared with the normal adjacent prostate. Immunostaining confirmed E-cadherin downregulation and revealed a discontinuous E-cadherin staining pattern in BPH specimens. E-cadherin knockdown increased monolayer permeability and disrupted tight junction formation without affecting cell density. CONCLUSIONS: Our results indicate that tight junctions are compromised in BPH and loss of E-cadherin is potentially an important underlying mechanism, suggesting targeting E-cadherin loss could be a potential approach to prevent or treat BPH.

RESUMEN

OBJECTIVES: To describe the rate and determinants of palliative care use amongst Medicare beneficiaries with bladder cancer and encourage a national dialogue on improving coordinated urological, oncological, and palliative care in patients with genitourinary malignancies. PATIENTS AND METHODS: Using Surveillance, Epidemiology, and End Results-Medicare data, we identified patients diagnosed with muscle-invasive bladder cancer (MIBC) between 2008 and 2013. Our primary outcome was receipt of palliative care, defined as the presence of a claim submitted by a Hospice and Palliative Medicine subspecialist. We examined determinants of palliative care use using logistic regression analysis. RESULTS: Over the study period, 7303 patients were diagnosed with MIBC and 262 (3.6%) received palliative care. Of 2185 patients with advanced bladder cancer, defined as either T4, N+ , or M+ disease, 90 (4.1%) received palliative care. Most patients that received palliative care (>80%, >210/262) did so within 24 months of diagnosis. On multivariable analysis, patients receiving palliative care were more likely to be younger, female, have greater comorbidity, live in the central USA, and have undergone radical cystectomy as opposed to a bladder-sparing approach. The adjusted probability of receiving palliative care did not significantly change over time. CONCLUSIONS: Palliative care provides a host of benefits for patients with cancer, including improved spirituality, decrease in disease-specific symptoms, and better functional status. However, despite strong evidence for incorporating palliative care into standard oncological care, use in patients with bladder cancer is low at 4%. This study provides a conservative baseline estimate of current palliative care use and should serve as a foundation to further investigate physician-, patient-, and system-level barriers to this care.

RESUMEN

PURPOSE: To describe the clinical characteristics, treatment patterns, and outcomes in patients with small cell bladder cancer at our institution, including those who received prophylactic cranial irradiation (PCI) for the prevention of intracranial recurrence. MATERIALS AND METHODS: Patients with small cell bladder cancer treated at a single institution between January 1990 and August 2015 were identified and analyzed retrospectively for demographics, tumor stage, treatment, and overall survival. RESULTS: Of 44 patients diagnosed with small cell bladder cancer, 11 (25%) had metastatic disease at the time of presentation. Treatment included systemic chemotherapy (70%), radical surgery (59%), and local radiation (39%). Six patients (14%) received PCI. Median overall survival was 10 months (IQR 4 - 41). Patients with extensive disease had worse overall survival than those with organ confined disease (8 months vs. 36 months, respectively, p = 0.04). Among those who received PCI, 33% achieved 5 - year survival. CONCLUSION: Outcomes for patients with small cell bladder cancer remain poor. Further research is indicated to determine if PCI increases overall survival in small call bladder cancer patients, especially those with extensive disease who respond to chemotherapy.

RESUMEN

OBJECTIVE: The purpose of this study was to develop an evidence-based method to optimize prostate MRI reports that would improve communication between urologists and radiologists. MATERIALS AND METHODS: This quality improvement initiative was approved by the institutional Quality Improvement Review Committee. A structured report was developed containing essential components defined by local practice norms and Prostate Imaging Reporting and Data System (PI-RADS) lexicon version 2. Two hundred preintervention and 100 postintervention reports were retrospectively reviewed for essential components. Additionally, a sample of 40 reports generated before the intervention and 40 reports generated after the intervention that made use of the structured report were evaluated by a urologist and were scored on a 5-point scale for consistency, completeness, conciseness, clarity, likelihood to contact radiologist, and clinical impact. Variables were compared with ANOVA, chi-square, or Fisher exact test. RESULTS: Essential components of the report were utilization of the PI-RADSv2 lexicon, findings listed by lesion, reporting of pertinent positive and negative findings (extraprostatic extension, seminal vesicle, and neurovascular bundle invasion), and low word count. In postintervention reports, all essential measures were statistically improved except for mean report word count. The urologist indicated statistically improved consistency (before intervention, 2.7; after intervention, 3.5; χ2 < 0.001), completeness (before intervention, 2.8; after intervention, 3.3; χ2 < 0.001), clarity (before intervention, 2.9; after intervention, 3.3; χ2 < 0.05), and clinical impact (before intervention, 2.8; after intervention, 3.8; χ2 < 0.001) of the report with reduced perceived need to contact (before intervention, 3.2; after intervention, 2.1; χ2 < 0.001) the interpreting radiologist for explanation. CONCLUSION: The structured prostate MRI report resulted in improved communication with referring urologists as indicated by the increased perceived clinical impact of the report.

RESUMEN

INTRODUCTION: Multimodal analgesia is an effective way to control pain and limit opioid use after surgery. The quadratus lumborum block and paravertebral block are two regional anesthesia techniques that leverage multimodal analgesia to improve postoperative pain control. We sought to compare the efficacy of these blocks for pain management following radical cystectomy. MATERIALS AND METHODS: We performed a retrospective review of radical cystectomy patients who received bilateral continuous paravertebral blocks (n = 125) or bilateral single shot quadratus lumborum blocks (n = 50) between 2014-2016. The primary outcome was postoperative opiate consumption on day 0. Secondary outcomes included self-reported pain scores and hospital length of stay. RESULTS: Quadratus lumborum block patients had similar opioid use on postoperative day 0 compared with paravertebral block patients (29 mg versus 30 mg, p = 0.90). Pain scores on postoperative day 0 were similar between quadratus lumborum block and paravertebral block groups (4.0 versus 3.8, p = 0.72); however, the paravertebral block group had lower pain scores on days 1-3 compared with the quadratus lumborum block group (all p < 0.05). Hospital length of stay was similar between groups (6.6 days versus 6.2 days, p = 0.41). CONCLUSIONS: There were no differences in opioid consumption among patients receiving bilateral single shot quadratus lumborum blocks and bilateral continuous paravertebral blocks after radical cystectomy. These data suggest that the quadratus lumborum block is a viable alternative for delivering multimodal analgesia in cystectomy patients.

RESUMEN

BACKGROUND: Interactions between industry and prescribers have raised concerns regarding conflicts of interest. To the best of the authors' knowledge, quantitative data measuring these interactions have been limited until recently. In the current study, the authors sought to determine whether an association exists between industry payments and prescriber behavior with regard to abiraterone and enzalutamide. METHODS: Two Centers for Medicare and Medicaid Services databases were combined to analyze oncologists and urologists who received industry payments and/or prescribed abiraterone and enzalutamide. Correlation analysis was constructed on prescription count and industry payments. Multivariable median regression examined predictors of change in prescription count per dollar of industry payment. Stratifying prescribers by quantile evaluated threshold effects on prescribers. RESULTS: The number of prescriptions was similar between prescribers who did and those who did not receive industry payment for both drugs. The median industry payment amount to prescribers differed between prescribers and nonprescribers for abiraterone ($72 vs $56) and enzalutamide ($59 vs $31). Although no statistical association was found to exist between industry payment amount and prescription count for abiraterone prescribers, an association was found to exist for enzalutamide prescribers (rho = 0.31). A small change was found with regard to prescription count per dollar of industry payment for abiraterone (0.0007 prescriptions) and enzalutamide (0.0006 prescriptions). The amount of industry payment needed to predict one additional prescription was found to be lower in the fourth and fifth quantiles compared with the first through third quantiles. CONCLUSIONS: No difference in prescription count was found to exist between prescribers who received industry payments and those who did not. A positive correlation was noted between industry payments and prescription count for enzalutamide. Ease of adoption may affect differences between the 2 drugs.

RESUMEN

PURPOSE: Prostate biopsy rates have paralleled decreasing prostate specific antigen screening rates since 2012. We hypothesized that biopsy rates and the change in rates since 2012 would vary considerably across hospital referral regions. MATERIALS AND METHODS: Using Medicare data from 2012 through 2014 we identified prostate biopsies performed by physicians who performed 11 or more biopsies annually. We calculated annual biopsy rates and changes in rates from 2012 to 2014 across 306 hospital referral regions. We performed multivariable regression adjusting for factors associated with annual biopsy rates (eg percent of patients older than 75 who were screened with prostate specific antigen and percent of the population that was African American). We also estimated adjusted prostate biopsy rates and changes with time across regions. RESULTS: We identified 395,993 biopsies. The overall rates decreased from 11.68 biopsies per 1,000 men in 2012 to 10.23 per 1,000 in 2014 (-12.4%, p = 0.11). Biopsy rates were higher in regions in which a greater percentage of the population was African American (ß = 0.810, 95% CI 0.235-1.384, p = 0.006), ambulatory surgical centers were available where biopsy could be performed (ß = 0.892, 95% CI 0.108-1.676, p = 0.026) and prostate specific antigen testing occurred more frequently (ß = 2.462, 95% CI 1.153-3.771, p <0.001). There was marked geographic variation in the adjusted average biopsy rate (median adjusted rate 9.08 biopsies per 1,000 men, IQR 7.65-10.76) and in the change in biopsy rates with time (median adjusted rate change -1.49 biopsies per 1,000 men, IQR -1.94--1.22 per 1,000). CONCLUSIONS: Since 2012 there has been considerable geographic variation in the performance of prostate biopsies as well as changes with time after prostate specific antigen recommendations changed. Characterizing the role of unmeasured patient and physician level factors is crucial to optimize the use and minimize the harms of prostate biopsy.

RESUMEN

INTRODUCTION: To investigate the use of a high-arginine immunonutrient supplement prior to radical cystectomy for bladder cancer. MATERIALS AND METHODS: We recruited 40 patients to consume a total of four high-arginine immunonutrient shakes per day for 5 days prior to radical cystectomy. The primary outcome measures were safety, tolerability and adherence to the supplementation regimen. Ninety-day postoperative outcomes were also compared between supplemented patients and a cohort of 104 prospectively identified non-supplemented radical cystectomy patients. Multivariable logistic regression models were used to compare overall complications, infectious complications, and readmission rates between groups. RESULTS: There were no serious adverse events during supplementation. Four patients (10%) stopped supplementation due to nausea (n = 2) and bloating (n = 2). Thirty-three patients (83%) consumed all prescribed shakes. Immunonutrient supplementation was not significantly associated with overall complications (adjusted odds ratio [OR] 1.08; 95% confidence interval [CI] 0.50-2.33), infectious complications (OR 1.23; 95% CI 0.49-3.07), or readmissions (OR 1.48; 95% CI 0.62-3.51) on multivariable analyses. CONCLUSIONS: Preoperative supplementation with a high-arginine immunonutrient shake was safe and well tolerated prior to radical cystectomy. Contrary to prior reports, immunonutrient supplementation was not associated with lower postoperative infectious complications in this cohort, perhaps owing to the 5 day supplementation period. Further study is needed to identify the optimal immunonutrient supplement regimen for radical cystectomy patients.

RESUMEN

BACKGROUND AND OBJECTIVES: To evaluate whether urologic procedures during cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) are associated with adverse postoperative outcomes. METHODS: We identified patients who underwent CRS-HIPEC at our institution from 2001 to 2012 and compared outcomes between operations that did and did not include a urologic procedure. RESULTS: A total of 938 CRS-HIPEC procedures were performed, 71 of which included a urologic intervention. Urologic interventions were associated with longer operative times (547 vs. 459 min, P < 0.001) and greater length of stay (15 vs. 12 days, P = 0.003). Major complications (Clavien III and IV) were more common in the urologic group (31% vs. 20%, P = 0.028). On multivariable analysis, urologic procedures were associated with a low anterior resection (OR: 2.25, 95%CI 1.07-4.74, P = 0.033) and a greater number of enteric anastomoses (OR: 1.83, 95%CI 1.31-2.56, P < 0.001). At a median follow up of 17 months (IQR 5.6-35 months), addition of a urologic procedure did not significantly impact overall survival for appendiceal or colorectal cancers. CONCLUSION: Urologic surgery at the time of CRS-HIPEC is associated with longer operative times, length of stay and increased risk of major complications, but not with decreased overall survival. J.

RESUMEN

INTRODUCTION: Horseshoe kidney is the most common congenital renal fusion anomaly, with an estimated incidence of 1.7 to 2.5 cases per 1000 live births. In these patients, nephron-sparing surgical management of renal tumors may be complicated by abnormal renal location, aberrant vasculature, and the presence of a renal isthmus. We present the largest known series of patients with renal malignancy in horseshoe kidneys managed by partial or hemi-nephrectomy with associated outcomes. MATERIALS AND METHODS: A retrospective review of our institution's electronic medical record was conducted to identify consecutive cases over an 11 year period. Pediatric patients and those who underwent surgery for benign indications were excluded from analysis. RESULTS: Eight patients with horseshoe kidney who underwent partial or hemi-nephrectomy for renal malignancy were identified. Median tumor size was 6.0 cm (IQR 3.7 cm-9.5 cm). Six patients had clear cell renal cell carcinoma (RCC), 1 patient had papillary RCC, and 1 patient had a renal carcinoid tumor with concurrent adenocarcinoma. Median length of stay was 4 days (IQR 2-.5.5 days). Median perioperative change in eGFR was -6 mL/min/1.73² (IQR -2.6-8.6 mL/min/1.73m²). One patient developed postoperative urine leak requiring percutaneous drainage and ureteral stent placement. Median follow up was 38.5 months, with a cancer-specific survival of 87.5% and an overall survival of 62.5%. CONCLUSION: Partial and hemi-nephrectomy for renal malignancy can safely be performed in patients with horseshoe kidney with acceptable operative and oncologic outcomes.
