Barriers to rural health care from the provider perspective.

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.

Large reduction in opioid prescribing by a multipronged behavioral intervention after major urologic surgery.

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.

Clinical Trials in Urology: Predictors of Successes and Failures.

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.

Under Treatment of Prostate Cancer in Rural Locations.

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.

The Influence of Stereotactic Body Radiation Therapy Adoption on Prostate Cancer Treatment Patterns.

PURPOSE: To our knowledge it is unknown whether stereotactic body radiation therapy of prostate cancer is a substitute for other radiation treatments or surgery, or for expanding the pool of patients who undergo treatment instead of active surveillance. MATERIALS AND METHODS: Using SEER (Surveillance, Epidemiology, and End Results)-Medicare we identified men diagnosed with prostate cancer between 2007 and 2011. We developed physician-hospital networks by identifying the treating physician of each patient based on the primary treatment received and subsequently assigning each physician to a hospital. We examined the relative distribution of prostate cancer treatments stratified by whether stereotactic body radiation therapy was performed in a network by fitting logistic regression models with robust SEs to account for patient clustering in networks. RESULTS: We identified 344 physician-hospital networks, including 30 (8.7%) and 314 (91.3%) in which stereotactic body radiation therapy was and was not performed, respectively. Networks in which that therapy was and was not done did not differ with time in the performance of robotic and radical prostatectomy, and active surveillance (all p >0.05). The relationship with intensity modulated radiation therapy did not show any consistent temporal pattern. In networks in which it was performed less intensity modulated radiation therapy was initially done but there were similar rates in later years. Brachytherapy trends differed among networks in which stereotactic body radiation therapy was vs was not performed with a lower brachytherapy rate in networks in which stereotactic body radiation therapy was done (p=0.03). CONCLUSIONS: Surgery and active surveillance rates did not differ in networks in which stereotactic body radiation therapy was vs was not performed but when that therapy was done there was a lower brachytherapy rate. Stereotactic body radiation therapy may represent more of an alternative to brachytherapy than to active surveillance.

Increasing use of positron emission tomography among medicare beneficiaries undergoing radical cystectomy.

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.

Radiation oncologists' attitudes and beliefs about intensity-modulated radiation therapy and stereotactic body radiation therapy for prostate cancer.

BACKGROUND: To better understand how radiation oncologists perceive intensity-modulated radiation therapy (IMRT) and stereotactic body radiation therapy (SBRT) for prostate cancer and how these perceptions may influence treatment decisions. METHODS: We conducted semi-structured interviews of radiation oncologists between January-May, 2016. We used a purposeful sampling technique to select participants across a wide range of experience, regions, and practice types. Two trained qualitative researchers used an inductive, iterative approach to code transcripts and identify themes. We then used content analysis and thematic analysis of the coded transcripts to understand radiation oncologists' attitudes and beliefs about IMRT and SBRT. RESULTS: Thematic saturation was achieved after 20 interviews. Participants were affiliated with academic (n = 13; 65%), private (n = 5; 25%), and mixed (n = 2; 10%) practices and had a wide range of clinical experience (median 19 years; range 4-49 years). Analysis of interview transcripts revealed four general themes: 1) most radiation oncologists offered surgery, brachytherapy, IMRT, and active surveillance for low-risk patients; 2) there was no consensus on the comparative effectiveness of IMRT and SBRT; 3) key barriers to adopting SBRT included issues related to insurance, reimbursement, and practice inertia; and 4) despite these barriers, most participants envisioned SBRT use increasing over the next 5-10 years. CONCLUSIONS: In the absence of strong opinions about effectiveness, nonclinical factors influence the choice of radiation treatment. Despite a lack of consensus, most participants agreed SBRT may become a standard of care in the future.

Reversal of the Warburg phenomenon in chemoprevention of prostate cancer by sulforaphane.

Inhibition of metabolic re-programming represents an attractive approach for prevention of prostate cancer. Studies have implicated increased synthesis of fatty acids or glycolysis in pathogenesis of human prostate cancers. We have shown previously that prostate cancer prevention by sulforaphane (SFN) in Transgenic Adenocarcinoma of Mouse Prostate (TRAMP) model is associated with inhibition of fatty acid metabolism. This study utilized human prostate cancer cell lines (LNCaP, 22Rv1 and PC-3), two different transgenic mouse models (TRAMP and Hi-Myc) and plasma specimens from a clinical study to explore the glycolysis inhibition potential of SFN. We found that SFN treatment: (i) decreased real-time extracellular acidification rate in LNCaP, but not in PC-3 cell line; (ii) significantly downregulated expression of hexokinase II (HKII), pyruvate kinase M2 and/or lactate dehydrogenase A (LDHA) in vitro in cells and in vivo in neoplastic lesions in the prostate of TRAMP and Hi-Myc mice; and (iii) significantly suppressed glycolysis in prostate of Hi-Myc mice as measured by ex vivo1H magnetic resonance spectroscopy. SFN treatment did not decrease glucose uptake or expression of glucose transporters in cells. Overexpression of c-Myc, but not constitutively active Akt, conferred protection against SFN-mediated downregulation of HKII and LDHA protein expression and suppression of lactate levels. Examination of plasma lactate levels in prostate cancer patients following administration of an SFN-rich broccoli sprout extract failed to show declines in its levels. Additional clinical trials are needed to determine whether SFN treatment can decrease lactate production in human prostate tumors.

E-cadherin is downregulated in benign prostatic hyperplasia and required for tight junction formation and permeability barrier in the prostatic epithelial cell monolayer.

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.

Association Between Hospital Participation in Medicare Shared Savings Program Accountable Care Organizations and Readmission Following Major Surgery.

OBJECTIVE: To evaluate the effect of Medicare Shared Savings Program accountable care organizations (ACOs) on hospital readmission after common surgical procedures. SUMMARY BACKGROUND DATA: Hospital readmissions following surgery lead to worse patient outcomes and wasteful spending. ACOs, and their associated hospitals, have strong incentives to reduce readmissions from 2 distinct Centers for Medicare and Medicaid Services policies. METHODS: We performed a retrospective cohort study using a 20% national Medicare sample to identify beneficiaries undergoing 1 of 7 common surgical procedures-abdominal aortic aneurysm repair, colectomy, cystectomy, prostatectomy, lung resection, total knee arthroplasty, and total hip arthroplasty-between 2010 and 2014. The primary outcome was 30-day risk-adjusted readmission rate. We performed difference-in-differences analyses using multilevel logistic regression models to quantify the effect of hospital ACO affiliation on readmissions following these procedures. RESULTS: Patients underwent a procedure at one of 2974 hospitals, of which 389 were ACO affiliated. The 30-day risk-adjusted readmission rate decreased from 8.4% (95% CI, 8.1-8.7%) to 7.0% (95% CI, 6.7-7.3%) for ACO affiliated hospitals (P < 0.001) and from 7.9% (95% CI, 7.8-8.0%) to 7.1% (95% CI, 6.9-7.2%) for non-ACO hospitals (P < 0.001). The difference-in-differences of the 2 trends demonstrated an additional 0.52% (95% CI, 0.97-0.078%) absolute reduction in readmissions at ACO hospitals (P = 0.021), which would translate to 4410 hospitalizations avoided. CONCLUSION: Readmissions following common procedures decreased significantly from 2010 to 2014. Hospital affiliation with Shared Savings ACOs was associated with significant additional reductions in readmissions. This emphasis on readmission reduction is 1 mechanism through which ACOs improve value in a surgical population.

Palliative care use amongst patients with bladder cancer.

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.

Characterising 'bounce-back' readmissions after radical cystectomy.

OBJECTIVE: To examine predictors of early readmissions after radical cystectomy (RC). Factors associated with preventable readmissions may be most evident in readmissions that occur within 3 days of discharge, commonly termed 'bounce-back' readmissions, and identifying such factors may inform efforts to reduce surgical readmissions. PATIENTS AND METHODS: We utilised the Healthcare Cost and Utilization Project's State Inpatient Databases to examine 1867 patients undergoing RC in 2009 and 2010, and identified all patients readmitted within 30 days of discharge. We assessed differences between patients experiencing bounce-back readmission compared to those readmitted 8-30 days after discharge using logistic regression models and also calculated abbreviated LACE scores to assess the utility of common readmissions risk stratification algorithms. RESULTS: The 30-day and bounce-back readmission rates were 28.4% and 5.6%, respectively. Although no patient or index hospitalisation characteristics were significantly associated with bounce-back readmissions in adjusted analyses, bounce-back patients did have higher rates of gastrointestinal (14.3% vs 6.7%, P = 0.02) and wound (9.5% vs 3.0%, P < 0.01) diagnoses, as well as increased index and readmission length of stay (5 vs 4 days, P = 0.01). Overall, the median abbreviated LACE score was 7, which fell into the moderate readmission risk category, and no difference was observed between readmitted and non-readmitted patients. CONCLUSION: One in five readmissions after RC occurs within 3 days of initial discharge, probably due to factors present at discharge. However, sociodemographic and clinical factors, as well as traditional readmission risk tools were not predictive of this bounce-back. Effective strategies to reduce bounce-back readmission must identify actionable clinical factors prior to discharge.

Role of Post-Acute Care on Hospital Readmission After High-Risk Surgery.

BACKGROUND: Payment models, including the Hospital Readmissions Reduction Program and bundled payments, place pressures on hospitals to limit readmissions. Against this backdrop, we sought to investigate the association of post-acute care after major surgery and readmission rates. METHODS: We identified patients undergoing high-risk surgery (abdominal aortic aneurysm repair, coronary bypass grafting, aortic valve replacement, carotid endarterectomy, esophagectomy, pancreatectomy, lung resection, and cystectomy) from 2005 to 2010 using the Healthcare Cost and Utilization Project's State Inpatient Database. The primary outcome was readmission rates after major surgery. Secondary outcome was readmission length of stay. RESULTS: We identified 135,523 patients of whom 56,720 (42%) received post-acute care. Patients receiving post-acute care had higher readmission rates than those who were discharged home (16% versus 10%, respectively; P < 0.001). The risk-adjusted readmission length of stay was greatest for patients who received care from a skilled nursing facility, followed by those who received home care, and lowest for those who did not receive post-acute care (7.1 versus 5.4 versus 4.8 d, respectively; P < 0.001). CONCLUSIONS: The use of post-acute care was associated with higher readmission rates and higher readmission lengths of stay. Improving the support of patients in post-acute care settings may help reduce readmissions and readmission intensity.

Small cell bladder cancer: should we consider prophylactic cranial irradiation?

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.

Prostate cancer chemoprevention by sulforaphane in a preclinical mouse model is associated with inhibition of fatty acid metabolism.

Increased de novo synthesis of fatty acids is a rather unique and targetable mechanism of human prostate cancer. We have shown previously that oral administration of sulforaphane (SFN) significantly inhibits the incidence and/or burden of prostatic intraepithelial neoplasia and well-differentiated adenocarcinoma in TRansgenic Adenocarcinoma of Mouse Prostate (TRAMP) mice. The present study used cellular models of prostate cancer and archived plasma/adenocarcinoma tissues and sections from the TRAMP study to demonstrate inhibition of fatty acid synthesis by SFN treatment in vitro and in vivo. Treatment of androgen-responsive (LNCaP) and castration-resistant (22Rv1) human prostate cancer cells with SFN (5 and 10 µM) resulted in downregulation of protein and mRNA levels of acetyl-CoA carboxylase 1 (ACC1) and fatty acid synthase (FASN), but not ATP citrate lyase. Protein and mRNA levels of carnitine palmitoyltransferase 1A (CPT1A), which facilitates fatty acid uptake by mitochondria for ß-oxidation, were also decreased following SFN treatment in both cell lines. Immunohistochemistry revealed a significant decrease in expression of FASN and ACC1 proteins in prostate adenocarcinoma sections of SFN-treated TRAMP mice when compared with controls. SFN administration to TRAMP mice resulted in a significant decrease in plasma and/or prostate adenocarcinoma levels of total free fatty acids, total phospholipids, acetyl-CoA and ATP. Consistent with these results, number of neutral lipid droplets was lower in the prostate adenocarcinoma sections of SFN-treated TRAMP mice than in control tumors. Collectively, these observations indicate that prostate cancer chemoprevention by SFN in TRAMP mice is associated with inhibition of fatty acid metabolism.

Early effect of Medicare Shared Savings Program accountable care organization participation on prostate cancer care.

BACKGROUND: Accountable care organizations (ACOs) can improve prostate cancer care by decreasing treatment variations (ie, avoidance of treatment in low-value settings). Herein, the authors performed a study to understand the effect of Medicare Shared Savings Program ACOs on prostate cancer care. METHODS: Using a 20% Medicare sample, the authors identified men with newly diagnosed prostate cancer from 2010 through 2013. Rates of treatment, potential overtreatment (ie, treatment in men with a ≥75% chance of 10-year mortality from competing risks), and Medicare payments were measured using regression models. The impact of ACO participation was assessed using difference-in-differences analyses. RESULTS: Before implementation of ACOs, the treatment rate was 71.8% (95% confidence interval [95% CI], 70.2%-73.3%) for ACO-aligned beneficiaries and 72.3% (95% CI, 71.7%-73.0% [P = .51]) for non-ACO-aligned beneficiaries. After implementation, this rate declined to 68.4% (95% CI, 66.1%-70.7% [P = .017]) for ACO-aligned beneficiaries and 69.3% (95% CI, 68.5%-70.1% [P<.001]) for non-ACO-aligned beneficiaries. There was no differential effect noted for ACO participation. The rate of potential overtreatment decreased from 48.2% (95% CI, 43.1%-53.3%) to 40.2% (95% CI, 32.4%-48.0% [P = .087]) for ACO-aligned beneficiaries and increased from 44.3% (95% CI, 42.1%-46.5%) to 47.0% (95% CI, 44.5%-49.5% [P = .11]) for non-ACO-aligned beneficiaries. These changes resulted in a significant relative decrease in overtreatment of 17% for ACO-aligned beneficiaries (difference-in-differences, 10.8%; P = .031). Payments were not found to be differentially affected by ACO alignment. CONCLUSIONS: The treatment of prostate cancer and annual payments decreased significantly between 2010 and 2013, but ACO participation did not appear to impact these trends. Among men least likely to benefit, Medicare Shared Savings Program ACO alignment was associated with a significant decline in prostate cancer treatment.

Risk of Radiation from Computerized Tomography Urography in the Evaluation of Asymptomatic Microscopic Hematuria.

PURPOSE: The AUA (American Urological Association) guidelines for asymptomatic microscopic hematuria recommend that patients undergo computerized tomography urography, which is associated with high doses of ionizing radiation. To our knowledge the associated risk of secondary malignancy and mortality remains unknown. We modeled the risk of malignancy and associated mortality due to ionizing radiation from computerized tomography urography relative to the additional diagnostic benefit offered over renal ultrasound. MATERIALS AND METHODS: We performed a PubMed® based literature search to identify model inputs. We obtained estimates of age and gender specific radiation induced secondary malignancy and mortality rates from the BEIR (Biologic Effects of Ionizing Radiation) VII Phase 2 report with dose extrapolation using the linear no threshold model. RESULTS: Patients with asymptomatic microscopic hematuria had a 0.053% and 0.48% prevalence of upper tract urothelial carcinoma and renal cell carcinoma, respectively. Ultrasound had 77% sensitivity for upper tract urothelial carcinoma and 82% sensitivity for renal cell carcinoma. The effective radiation dose of computerized tomography urography was 31.7 mSv. Based on these inputs a population of 100,000 patients with asymptomatic microscopic hematuria would include 53.1 and 478 patients with upper tract urothelial carcinoma and renal cell carcinoma, respectively. On ultrasound alone 98.2 cases of upper urinary tract malignancy would be missed. An additional 149 cases of secondary malignancy would be caused by computerized tomography urography associated radiation with 101 fatalities. A total of 1,018.3 computerized tomography urography studies would need to be performed to detect an additional case of upper tract malignancy. CONCLUSIONS: Based on current risk models computerized tomography urography for asymptomatic microscopic hematuria may be associated with a small but significant risk of secondary malignancy relative to the additional diagnostic benefit offered.

The United States opioid epidemic: a review of the surgeon's contribution to it and health policy initiatives.

Opioid abuse and addiction is causing widespread devastation in communities across the USA and resulting in significant strain on our healthcare system. There is increasing evidence that prescribers are at least partly responsible for the opioid crisis because of overprescribing, a practice that developed from changes in policy and reimbursement structures. Surgeons, specifically, have been subject to scrutiny as 'adequate treatment' of post-surgical pain is poorly defined and data suggest that many patients receive much larger opioid prescriptions than needed. The consequences of overprescribing include addiction and misuse, dispersion of opioids into the community, and possible potentiation of illicit drug/heroin use. Several solutions to this crisis are currently being enacted with variable success, including Prescription Drug Monitoring Programmes, policy-level interventions aimed to de-incentivize overprescribing, limiting opioid exposures through Enhanced Recovery After Surgery protocols, and the novel idea of creating surgery- and/or procedure-specific prescribing guidelines. This problem is likely to require not one, but several potential solutions to reverse its trajectory. It is critical, however, that we as physicians and prescribers find a way to stop the needless overprescribing while still treating postoperative pain appropriately.

Evidence-Based Reporting: A Method to Optimize Prostate MRI Communications With Referring Physicians.

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.

The comparative effectiveness of quadratus lumborum blocks and paravertebral blocks in radical cystectomy patients.

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.
