RESUMO
BACKGROUND: Many men with prostate cancer will be exposed to androgen deprivation therapy (ADT). While evidence-based ADT use is common, ADT is also used in cases with no or limited evidence resulting in more harm than benefit, i.e., overuse. Since there are risks of ADT (e.g., diabetes, osteoporosis), it is important to understand the behaviors facilitating overuse to inform de-implementation strategies. For these reasons, we conducted a theory-informed survey study, including a discrete choice experiment (DCE), to better understand ADT overuse and provider preferences for mitigating overuse. METHODS: Our survey used the Action, Actor, Context, Target, Time (AACTT) framework, the Theoretical Domains Framework (TDF), the Capability, Opportunity, Motivation-Behavior (COM-B) Model, and a DCE to elicit provider de-implementation strategy preferences. We surveyed the Society of Government Service Urologists listserv in December 2020. We stratified respondents based on the likelihood of stopping overuse as ADT monotherapy for localized prostate cancer ("yes"/"probably yes," "probably no"/"no"), and characterized corresponding Likert scale responses to seven COM-B statements. We used multivariable regression to identify associations between stopping ADT overuse and COM-B responses. RESULTS: Our survey was completed by 84 respondents (13% response rate), with 27% indicating "probably no"/"no" to stopping ADT overuse. We found differences across respondents who said they would and would not stop ADT overuse in demographics and COM-B statements. Our model identified 2 COM-B domains (Opportunity-Social, Motivation-Reflective) significantly associated with a lower likelihood of stopping ADT overuse. Our DCE demonstrated in-person communication, multidisciplinary review, and medical record documentation may be effective in reducing ADT overuse. CONCLUSIONS: Our study used a behavioral theory-informed survey, including a DCE, to identify behaviors and context underpinning ADT overuse. Specifying behaviors supporting and gathering provider preferences in addressing ADT overuse requires a stepwise, stakeholder-engaged approach to support evidence-based cancer care. From this work, we are pursuing targeted improvement strategies. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03579680.
RESUMO
Importance: Non-Hispanic Black (hereafter, Black) individuals experience worse prostate cancer outcomes due to socioeconomic and racial inequities of access to care. Few studies have empirically evaluated these disparities across different health care systems. Objective: To describe the racial and ethnic and neighborhood socioeconomic status (nSES) disparities among residents of the same communities who receive prostate cancer care in the US Department of Veterans Affairs (VA) health care system vs other settings. Design, Setting, and Participants: This cohort study obtained data from the VA Central Cancer Registry for veterans with prostate cancer who received care within the VA Greater Los Angeles Healthcare System (VA cohort) and from the California Cancer Registry (CCR) for nonveterans who received care outside the VA setting (CCR cohort). The cohorts consisted of all males with incident prostate cancer who were living within the same US Census tracts. These individuals received care between 2000 and 2018 and were followed up until death from any cause or censoring on December 31, 2018. Data analyses were conducted between September 2022 and December 2023. Exposures: Health care setting, self-identified race and ethnicity (SIRE), and nSES. Main Outcomes and Measures: The primary outcome was all-cause mortality (ACM). Cox proportional hazards regression models were used to estimate hazard ratios for associations of SIRE and nSES with prostate cancer outcomes in the VA and CCR cohorts. Results: Included in the analysis were 49â¯461 males with prostate cancer. Of these, 1881 males were in the VA cohort (mean [SD] age, 65.3 [7.7] years; 833 Black individuals [44.3%], 694 non-Hispanic White [hereafter, White] individuals [36.9%], and 354 individuals [18.8%] of other or unknown race). A total of 47â¯580 individuals were in the CCR cohort (mean [SD] age, 67.0 [9.6] years; 8183 Black individuals [17.2%], 26 206 White individuals [55.1%], and 13 191 individuals [27.8%] of other or unknown race). In the VA cohort, there were no racial disparities observed for metastasis, ACM, or prostate cancer-specific mortality (PCSM). However, in the CCR cohort, the racial disparities were observed for metastasis (adjusted odds ratio [AOR], 1.36; 95% CI, 1.22-1.52), ACM (adjusted hazard ratio [AHR], 1.13; 95% CI, 1.04-1.24), and PCSM (AHR, 1.15; 95% CI, 1.05-1.25). Heterogeneity was observed for the racial disparity in ACM in the VA vs CCR cohorts (AHR, 0.90 [95% CI, 0.76-1.06] vs 1.13 [95% CI, 1.04-1.24]; P = .01). No evidence of nSES disparities was observed for any prostate cancer outcomes in the VA cohort. However, in the CCR cohort, heterogeneity was observed for nSES disparities with ACM (AHR, 0.82; 95% CI, 0.80-0.84; P = .002) and PCSM (AHR, 0.86; 95% CI, 0.82-0.89; P = .007). Conclusions and Relevance: Results of this study suggest that racial and nSES disparities were wider among patients seeking care outside of the VA health care system. Health systems-related interventions that address access barriers may mitigate racial and socioeconomic disparities in prostate cancer.

BACKGROUND: Men with prostate cancer are often treated with the suppression of testosterone through long-acting injectable drugs termed chemical castration or androgen deprivation therapy (ADT). In most cases, ADT is not an appropriate treatment for localized prostate cancer, indicating low-value care. Guided by the Theoretical Domains Framework (TDF) and the Behavior Change Wheel's Capability, Opportunity, Motivation Model (COM-B), we conducted a qualitative study to identify behavioral determinants of low-value ADT use to manage localized prostate cancer, and theory-based opportunities for de-implementation strategy development. METHODS: We used national cancer registry and administrative data from 2016 to 2017 to examine the variation in low-value ADT use across Veterans Health Administration facilities. Using purposive sampling, we selected high- and low-performing sites to conduct 20 urology provider interviews regarding low-value ADT. We coded transcripts into TDF domains and mapped content to the COM-B model to generate a conceptual framework for addressing low-value ADT practices. RESULTS: Our interview findings reflected provider perspectives on prescribing ADT as low-value localized prostate cancer treatment, including barriers and facilitators to de-implementing low-value ADT. We characterized providers as belonging in 1 of 3 categories with respect to low-value ADT use: 1) never prescribe 2); willing, under some circumstances, to prescribe: and 3) prescribe as an acceptable treatment option. Provider capability to prescribe low-value ADT depended on their knowledge of localized prostate cancer treatment options (knowledge) coupled with interpersonal skills to engage patients in educational discussion (skills). Provider opportunity to prescribe low-value ADT centered on the environmental resources to inform ADT decisions (e.g., multi-disciplinary review), perceived guideline availability, and social roles and influences regarding ADT practices, such as prior training. Provider motivation involved goals of ADT use, including patient preferences, beliefs in capabilities/professional confidence, and beliefs about the consequences of prescribing or not prescribing ADT. CONCLUSIONS: Use of the TDF domains and the COM-B model enabled us to conceptualize provider behavior with respect to low-value ADT use and clarify possible areas for intervention to effect de-implementation of low-value ADT prescribing in localized prostate cancer.

RESUMO
PURPOSE: Prostate cancer (PCa) is among the leading causes of cancer deaths. While localized PCa has a 5-year survival rate approaching 100%, this rate drops to 31% for metastatic prostate cancer (mPCa). Thus, timely identification of mPCa is a crucial step toward measuring and improving access to innovations that reduce PCa mortality. Yet, methods to identify patients diagnosed with mPCa remain elusive. Cancer registries provide detailed data at diagnosis but are not updated throughout treatment. This study reports on the development and validation of a natural language processing (NLP) algorithm deployed on oncology, urology, and radiology clinical notes to identify patients with a diagnosis or history of mPCa in the Department of Veterans Affairs. PATIENTS AND METHODS: Using a broad set of diagnosis and histology codes, the Veterans Affairs Corporate Data Warehouse was queried to identify all Veterans with PCa. An NLP algorithm was developed to identify patients with any history or progression of mPCa. The NLP algorithm was prototyped and developed iteratively using patient notes, grouped into development, training, and validation subsets. RESULTS: A total of 1,144,610 Veterans were diagnosed with PCa between January 2000 and October 2020, among which 76,082 (6.6%) were identified by NLP as having mPCa at some point during their care. The NLP system performed with a specificity of 0.979 and sensitivity of 0.919. CONCLUSION: Clinical documentation of mPCa is highly reliable. NLP can be leveraged to improve PCa data. When compared to other methods, NLP identified a significantly greater number of patients. NLP can be used to augment cancer registry data, facilitate research inquiries, and identify patients who may benefit from innovations in mPCa treatment.

PURPOSE: We examined changes in urological care delivery due to COVID-19 in the U.S. based on patient, practice, and local/regional demographic and pandemic response features. MATERIALS AND METHODS: We analyzed real-world data from the American Urological Association Quality (AQUA) Registry collected from electronic health record systems. Data represented 157 outpatient urological practices and 3,165 providers across 48 U.S. states and territories, including 3,297,721 unique patients, 12,488,831 total outpatient visits and 2,194,456 procedures. The primary outcome measure was the number of outpatient visits and procedures performed (inpatient or outpatient) per practice per week, measured from January 2019 to February 2021. RESULTS: We found large (>50%) declines in outpatient visits from March 2020 to April 2020 across patient demographic groups and states, regardless of timing of state stay-at-home orders. Nonurgent outpatient visits decreased more across various nonurgent procedures (49%-59%) than for procedures performed for potentially urgent diagnoses (38%-52%); surgical procedures for nonurgent conditions also decreased more (43%-79%) than those for potentially urgent conditions (43%-53%). African American patients had similar decreases in outpatient visits compared with Asians and Caucasians, but also slower recoveries back to baseline. Medicare-insured patients had the steepest declines (55%), while those on Medicaid and government insurance had the lowest percentage of recovery to baseline (73% and 69%, respectively). CONCLUSIONS: This study provides real-world evidence on the decline in urological care across demographic groups and practice settings, and demonstrates a differential impact on the utilization of urological health services by demographics and procedure type.

Objective: Telehealth is increasingly used in urology, but few studies have evaluated how it can be integrated with urology face-to-face (FTF) encounters and primary care (PC). We describe the 5-year experience of a Veterans Affairs urology service that has incorporated telehealth into their patient care program. Methods: We performed a retrospective review of encounters from 2013 to 2018 in telehealth urology clinics. To examine the way telehealth and FTF visits were utilized together, the key components of care were defined for the evaluation of three common referrals: elevated prostate-specific antigen (PSA), microscopic hematuria, and obstructive lower urinary tract symptoms (LUTS). A random convenience sample of 20 patients from each condition was abstracted to describe the setting of care for each component over a 2-year period. Results: We reviewed 811 unique patients who had a total of 2,008 telehealth visits. The mean utilization of telehealth (2.48) and FTF (2.42) encounters per patient were similar. The most common reasons for referral to telehealth clinics were sexual dysfunction (26.8%), LUTS (20.6%), hematuria (15.0%), prostate cancer (13.3%), and an elevated PSA (12.1%). Thirty-six percent of patients were managed by telehealth alone; 64% were by a combination of telehealth and FTF encounters. Telehealth was often used in conjunction with PC and FTF visits to perform components such as the physical exam and procedures. Conclusions: Telehealth was utilized for a wide array of diseases and often used in conjunction with PC and urologic FTF visits to deliver complete care for the three disease states we evaluated.

PURPOSE: Accurate life expectancy estimates are required to inform prostate cancer treatment decisions. However, few models are specific to the population served or easily implemented in a clinical setting. We sought to create life expectancy estimates specific to Veterans diagnosed with prostate cancer. MATERIALS AND METHODS: Using national Veterans Health Administration electronic health records, we identified Veterans diagnosed with prostate cancer between 2000 and 2015. We abstracted demographics, comorbidities, oncologic staging, and treatment information. We fit Cox Proportional Hazards models to determine the impact of age, comorbidity, cancer risk, and race on survival. We stratified life expectancy estimates by age, comorbidity and cancer stage. RESULTS: Our analytic cohort included 145,678 patients. Survival modeling demonstrated the importance of age and comorbidity across all cancer risk categories. Life expectancy estimates generated from age and comorbidity data were predictive of overall survival (C-index 0.676, 95% CI 0.674-0.679) and visualized using Kaplan-Meier plots and heatmaps stratified by age and comorbidity. Separate life expectancy estimates were generated for patients with localized or advanced disease. These life expectancy estimates calibrate well across prostate cancer risk categories. CONCLUSIONS: Life expectancy estimates are essential to providing patient-centered prostate cancer care. We developed accessible life expectancy estimation tools for Veterans diagnosed with prostate cancer that can be used in routine clinical practice to inform medical-decision making.

OBJECTIVE: To characterize the contemporary management of prostate cancer patients in large community practices. The optimal management of incident prostate cancer has changed in the last decades to include active surveillance for a large number of men. At the same time, many community practices have merged into larger groups. The adoption of evidence-based guidelines is of increasing importance, but poorly understood in this newer practice setting. METHODS: We conducted a retrospective chart review of men ≤75 years old with very low, low, and intermediate risk incident prostate cancer diagnosed between December 1, 2012 and March 31, 2014, in 9 geographically distributed large urology practices. We used descriptive statistics and multivariable regression to assess predictors of primary management choice. RESULTS: 2029 men were in the study cohort. A majority were white (68.7%). Total of 45.7% had intermediate risk, 36.2% low risk, and 17.9% had very low risk disease cancer. Active surveillance (AS) was the initial treatment for 74.7% of men with very low risk disease, 43.5% of men with low risk disease and 10.8% of men with intermediate risk disease. The probability of choosing surgery vs radiation for men with lower and intermediate risk disease was 0.54 (95% confidence interval: 0.42, 0.65) and 0.59 (95% confidence interval: 0.48, 0.69), respectively. CONCLUSION: We found that the initial management of lower risk prostate cancer in large community urology practices largely followed clinical characteristics, widespread adoption of active surveillance, and equal use of surgery and radiation. However, some variation by practice suggested a need for further investigation and continued improvement.

PURPOSE: Accurate assessment of life expectancy is critical to treatment decision making in men with prostate cancer. We sought to externally validate the PCCI (Prostate Cancer Comorbidity Index) to predict long-term mortality in men with prostate cancer and make it operational using claims data. MATERIALS AND METHODS: We performed an observational study of 181,009 men with prostate cancer in the Veterans Affairs Health System who were diagnosed from 2000 to 2013. Overall mortality across the PCCI scores was analyzed using Kaplan-Meier and Cox proportional hazards analysis. Discrimination and calibration were measured using the C-index and the mean prediction error, respectively. RESULTS: Among men with a PCCI score of 0, 1-2, 3-4, 5-6, 7-9 and 10 or greater the 10-year overall mortality rate was 15%, 26%, 36%, 41%, 52% and 69%, respectively. Multivariable Cox analysis showed an increasing hazard of mortality with higher PCCI scores, including 1.22 (95% CI 1.18-1.27), 1.69 (95% CI 1.61-1.76), 2.08 (95% CI 2.00-2.17), 2.88 (95% CI 2.76-3.00) and 4.50 (95% CI 4.32-4.69) for a score of 1 to 2, 3 to 4, 5 to 6, 7 to 9 and 10 or greater, respectively. The C-index to predict overall mortality was 0.773. The mean absolute error to predict 10-year overall mortality was 0.032. Of the men with clinically localized disease, Gleason 6 or less with less than 10-year life expectancy and Gleason 7 or less with life expectancy less than 5 years as defined by the PCCI 3,999 of 12,185 (33%) and 1,038 of 3,930 (26%), respectively, underwent definitive local treatment. CONCLUSIONS: The PCCI is a claims based, externally validated tool to predict mortality in men with prostate cancer. Integrating the PCCI into clinical pathways may improve prostate cancer management through more accurate assessment of life expectancy.

OBJECTIVES: To determine the 3-year outcomes of men with prostate cancer managed with active surveillance (AS) in a cohort of geographically diverse community-based urology practices. AS is the management of choice for a majority of men with lower risk prostate cancer.1,2,3 Little is known about the contemporary "real-world" follow-up and adherence rates in the most common setting of urologic care, community (private) practice.4 METHODS: We retrospectively evaluated outcomes for men diagnosed between January 1, 2013 and May 31, 2014 with National Comprehensive Cancer Network (NCCN) very low, low and intermediate risk prostate cancer who selected AS in 9 large community urology practices. We used univariate and multivariate analyses to describe associations between race, age, insurance status, family history, comorbidity, clinical stage, Gleason score, NCCN risk-group, and PSA density with discontinuation of AS. RESULTS: Five hundred and forty-eight men on AS were followed for a median of 3.35 years. 89% (492) continued to follow-up with diagnosing practice. 32% (171) discontinued AS. On multivariate analysis, increasing NCCN risk classification (Hazard ratio [HR] 1.65, Pâ¯=â¯0.02 and HR 2.09, P < 0.01 for low and intermediate risk vs very low risk) was significantly associated with discontinuation. Among those who discontinued AS, surgery and radiation were utilized equally (47% and 53%, respectively, Pâ¯=â¯0.48). CONCLUSION: In this community-based cohort of men on AS, a minority was lost to follow-up and adherence to AS was similar to other reports. Disease characteristics more than sociodemographic characteristics correlated with adherence to AS, while surgery and radiotherapy were utilized equally among those discontinuing AS, both suggesting guideline concordant practice of medicine.

OBJECTIVES: To characterise bone scan use, and potential overuse, after radical prostatectomy (RP) using data from a large, national integrated delivery system. Overuse of imaging is well documented in the setting of newly diagnosed prostate cancer, but whether overuse persists after RP remains unknown. PATIENTS AND METHODS: We identified 12 269 patients with prostate cancer treated with RP between 2005 and 2008 using the Veterans Administration Central Cancer Registry. We used administrative and laboratory data to examine rates of bone scan use, including preceding prostate-specific antigen (PSA) levels, and receipt of adjuvant or salvage therapy. We then performed multivariable logistic regression to identify factors associated with post-RP bone scan use. RESULTS: At a median follow-up of 6.8 years, one in five men (22%) underwent a post-RP bone scan at a median PSA level of 0.2 ng/mL. Half of bone scans (48%) were obtained in men who did not receive further treatment with androgen-deprivation or radiation therapy. After adjustment, post-RP bone scan was associated with a prior bone scan (adjusted odds ratio [aOR] 1.55, 95% confidence interval [CI] 1.32-1.84), positive surgical margin (aOR 1.68, 95% CI 1.40-2.01), preoperative PSA level (aOR 1.02, 95% CI 1.01-1.03), as well as Hispanic ethnicity, Black race, and increasing D'Amico risk category, but not with age or comorbidity. CONCLUSION: We found a substantial rate of bone scan utilisation after RP. The majority were performed for PSA levels of <1 ng/mL where the likelihood of a positive test is low. More judicious use of imaging appears warranted in the post-RP setting.

BACKGROUND: Men with prostate cancer are often castrated with long-acting injectable drugs termed androgen deprivation therapy (ADT). Although many benefit, ADT is also used in patients with little or nothing to gain. The best ways to stop this practice are unknown, and range from blunt pharmacy restrictions to informed decision-making. This study will refine and pilot two different de-implementation strategies for reducing ADT use among those unlikely to benefit in preparation for a comparative effectiveness trial. METHODS/DESIGN: This innovative mixed methods research program has three aims. Aim 1: To assess preferences and barriers for de-implementation of chemical castration in prostate cancer. Guided by the theoretical domains framework (TDF), urologists and patients from facilities with the highest and lowest castration rates across the VA will be interviewed to identify key preferences and de-implementation barriers for reducing castration as prostate cancer treatment. This qualitative work will inform Aim 2 while gathering rich information for two proposed pilot intervention strategies. Aim 2: To use a discrete choice experiment (DCE), a novel barrier prioritization approach, for de-implementation strategy tailoring. The investigators will conduct national surveys of urologists to prioritize key barriers identified in Aim 1 for stopping incident castration as localized prostate cancer treatment using a DCE experiment design. These quantitative results will identify the most important barriers to be addressed through tailoring of two pilot de-implementation strategies in preparation for Aim 3 piloting. Aim 3: To pilot two tailored de-implementation strategies to reduce castration as localized prostate cancer treatment. Building on findings from Aims 1 and 2, two de-implementation strategies will be piloted. One strategy will focus on formulary restriction at the organizational level and the other on physician/patient informed decision-making at different facilities. Outcomes will include acceptability, feasibility, and scalability in preparation for an effectiveness trial comparing these two widely varying de-implementation strategies. DISCUSSION: Our innovative approach to de-implementation strategy development is directly aligned with state-of-the-art complex implementation intervention development and implementation science. This work will broadly advance de-implementation science for low value cancer care, and foster participation in our de-implementation evaluation trial by addressing barriers, facilitators, and concerns through pilot tailoring.

PURPOSE: We sought to characterize the effects of prostate specific antigen registry errors on clinical research by comparing cohorts based on cancer registry prostate specific antigen values with those based directly on results in the electronic health record. MATERIALS AND METHODS: We defined sample cohorts of men with prostate cancer using data from the Veterans Health Administration, including those with a prostate specific antigen value less than 4.0, 4.0 to 10.0, 10.0 to 20.0 and 20.0 to 98.0 ng/ml, respectively. We compared the composition of each cohort and overall patient survival when using prostate specific antigen values from the Veteran Affairs Central Cancer Registry vs the gold standard electronic health record laboratory file results. RESULTS: There was limited agreement among cohorts when defined by cancer registry prostate specific antigen values vs the laboratory file of the electronic health record. The least agreement of 58% was seen in patients with prostate specific antigen less than 4.0 ng/ml and greatest agreement of 89% was noted among patients with prostate specific antigen between 4.0 and 10.0 ng/ml. In each cohort patients assigned to a cohort based only on the cancer registry prostate specific antigen value had significantly different overall survival when compared with patients assigned based on registry and laboratory file prostate specific antigen values. CONCLUSIONS: Cohorts based exclusively on cancer registry prostate specific antigen values may have high rates of misclassification that can introduce concerning differences in key characteristics and result in measurable differences in clinical outcomes.

Implementation science is a rapidly developing field dedicated to the scientific investigation of strategies to facilitate improvements in healthcare delivery. These strategies have been shown in several settings to lead to more complete and sustained change. In this essay, we discuss how refined surveillance recommendations for non-muscle-invasive bladder cancer, which involve a complex interplay between providers, healthcare facilities, and patients, could benefit from use of implementation strategies derived from the growing literature of implementation science. These surveillance recommendations are based on international consensus and indicate that the frequency of surveillance cystoscopy should be aligned with each patient's risk for recurrence and progression of disease. Risk-aligned surveillance entails cystoscopy at 3 and 12 months followed by annual surveillance for low-risk cancers, with surveillance every 3 months reserved for high-risk cancers. However, risk-aligned care is not the norm. Implementing risk-aligned surveillance could curtail overuse among low-risk patients, while curbing underuse among high-risk patients. Despite clear direction from respected and readily available clinical guidelines, there are multiple challenges to implementing risk-aligned surveillance in a busy clinical setting. Here, we describe how implementation science methods can be systematically used to understand determinants of care and to develop strategies to improve care. We discuss how the tailored implementation for chronic diseases framework can facilitate systematic assessment and how intervention mapping can be used to develop implementation strategies to improve care. Taken together, these implementation science methods can help facilitate practice transformation to improve risk-aligned surveillance for bladder cancer.

OBJECTIVES: To assess bone-density testing (BDT) use amongst prostate cancer survivors receiving androgen-deprivation therapy (ADT), and downstream implications for osteoporosis and fracture diagnoses, as well as pharmacological osteoporosis treatment in a national integrated delivery system. PATIENTS AND METHODS: We identified 17 017 men with prostate cancer who received any ADT between 2005 and 2014 using the Veterans Health Administration cancer registry and administrative data. We identified claims for BDT within a 3-year period of ADT initiation. We then used multivariable regression to examine the association between BDT use and incident osteoporosis, fracture, and use of pharmacological treatment. RESULTS: We found that a minority of patients received BDT (n = 2 502, 15%); however, the rate of testing increased to >20% by the end of the study period. Men receiving BDT were older at diagnosis and had higher-risk prostate cancer (both P < 0.001). Osteoporosis and fracture diagnoses, use of vitamin D ± calcium, and bisphosphonates were all more common in men who received BDT. After adjustment, BDT, and to a lesser degree ≥2 years of ADT, were both independently associated with incident osteoporosis, fracture, and osteoporosis treatment. CONCLUSIONS: BDT is rare amongst patients with prostate cancer treated with ADT in this integrated delivery system. However, BDT was associated with substantially increased treatment of osteoporosis indicating an underappreciated burden of osteoporosis amongst prostate cancer survivors initiating ADT. Optimising BDT use and osteoporosis management in this at-risk population appears warranted.

INTRODUCTION: Rates of advance care planning for patients with cancer are poor despite efforts to enhance discussions regarding goals of care. Good patient-physician communication is critical to providing quality end-of-life care and, thus, it is important to identify effective interventions to improve systems through which patient preferences are addressed. METHODS: To improve rates of advance care planning as well as examine patient preferences regarding end-of-life care, we developed an integrated urology-palliative care clinic. All patients with a new diagnosis of a metastatic urological malignancy or castration resistant prostate cancer seen in a urology clinic within the Veterans Affairs Greater Los Angeles Healthcare System were offered a palliative care referral to be performed immediately after their urology appointment. The primary outcome was completion of an advance directive or POLST (Physician Orders for Life-Sustaining Treatment) form and the secondary outcome was patient preference regarding end-of-life care. RESULTS: A total of 59 patients were enrolled in the study between February 2012 and October 2016, and no patients were lost or excluded. There were 25 eligible patients who declined enrollment. Overall 85% of patients completed an advance directive or POLST form, and 98% chose to withhold cardiopulmonary resuscitation, advanced cardiac life support and artificially administered nutrition. CONCLUSIONS: High levels of advance care planning are achievable in an integrated urology-palliative care clinic and the majority of patients with a terminal illness are averse to aggressive end-of-life care.

BACKGROUND: For certain men with low-risk prostate cancer, aggressive treatment results in marginal survival benefits while exposing them to urinary and sexual side effects. Nevertheless, expectant management has been underused. In the current study, the authors evaluated the association between various factors and expectant management use among veterans diagnosed with prostate cancer. METHODS: The authors identified men diagnosed with prostate cancer in 2008. The outcome of interest was use of expectant management, based on documentation captured through an in-depth chart review. Multivariable regression models were fit to examine associations between use of expectant management and patient demographics, cancer severity, and facility characteristics. The authors assessed variation across 21 tertiary care regions and 52 facilities by generating predicted probabilities for receipt of expectant management. RESULTS: Expectant management was more common among patients aged ≥75 years (40% vs 27% for those aged < 55 years; odds ratio, 2.57) and those with low-risk tumors (49% vs 20% for patients with high-risk tumors; odds ratio, 5.35). There was no association noted between patient comorbidity and receipt of expectant management (P = .90). There were also no associations found between facility factors and use of expectant management (all P>.05). Among ideal candidates for expectant management, receipt of expectant management varied considerably across individual facilities (0%-85%; P<.001). CONCLUSIONS: Patient age and tumor risk were found to be more strongly associated with use of expectant management than patient comorbidity. Although use of expectant management appears broadly appropriate, there was variation in expectant management noted between hospitals that was apparently not attributable to facility factors. Research determining the basis of this variation, with a focus on providers, will be critical to help optimize prostate cancer treatment for veterans.
