The cost, survival, and quality-of-life implications of guideline-discordant imaging for prostate cancer.

BACKGROUND: National Comprehensive Cancer Network (NCCN) guidelines for incident prostate cancer staging imaging have been widely circulated and accepted as best practice since 1996. Despite these clear guidelines, wasteful and potentially harmful inappropriate imaging of men with prostate cancer remains prevalent. AIM: To understand changing population-level patterns of imaging among men with incident prostate cancer, we created a state-transition microsimulation model based on existing literature and incident prostate cancer cases. METHODS: To create a cohort of patients, we identified incident prostate cancer cases from 2004 to 2009 that were diagnosed in men ages 65 and older from SEER. A microsimulation model allowed us to explore how this cohort's survival, quality of life, and Medicare costs would be impacted by making imaging consistent with guidelines. We conducted a probabilistic analysis as well as one-way sensitivity analysis. RESULTS: When only imaging high-risk men compared to the status quo, we found that the population rate of imaging dropped from 53 to 38% and average per-person spending on imaging dropped from $236 to $157. The discounted and undiscounted incremental cost-effectiveness ratios indicated that ideal upfront imaging reduced costs and slightly improved health outcomes compared with current practice patterns, that is, guideline-concordant imaging was less costly and slightly more effective. CONCLUSION: This study demonstrates the potential reduction in cost through the correction of inappropriate imaging practices. These findings highlight an opportunity within the healthcare system to reduce unnecessary costs and overtreatment through guideline adherence.

Protocol: A multi-modal, physician-centered intervention to improve guideline-concordant prostate cancer imaging.

BACKGROUND: Almost half of Veterans with localized prostate cancer receive inappropriate, wasteful staging imaging. Our team has explored the barriers and facilitators of guideline-concordant prostate cancer imaging and found that (1) patients with newly diagnosed prostate cancer have little concern for radiographic staging but rather focus on treatment and (2) physicians trust imaging guidelines but are apt to follow their own intuition, fear medico-legal consequences, and succumb to influence from imaging-avid colleagues. We used a theory-based approach to design a multi-level intervention strategy to promote guideline-concordant imaging to stage incident prostate cancer. METHODS: We designed the Prostate Cancer Imaging Stewardship (PCIS) intervention: a multi-site, stepped wedge, cluster-randomized trial to determine the effect of a physician-focused behavioral intervention on Veterans Health Administration (VHA) prostate cancer imaging use. The multi-level intervention, developed according to the Theoretical Domains Framework (TDF) and Behavior Change Wheel, combines traditional physician behavior change methods with novel methods of communication and data collection. The intervention consists of three components: (1) a system of audit and feedback to clinicians informing individual clinicians and their sites about how their behavior compares to their peers' and to published guidelines, (2) a program of academic detailing with the goal to educate providers about prostate cancer imaging, and (3) a CPRS Clinical Order Check for potentially guideline-discordant imaging orders. The intervention will be introduced to 10 participating geographically distributed study sites. DISCUSSION: This study is a significant contribution to implementation science, providing VHA an opportunity to ensure delivery of high-quality care at the lowest cost using a theory-based approach. The study is ongoing. Preliminary data collection and recruitment have started; analysis has yet to be performed. TRIAL REGISTRATION: CliniclTrials.gov NCT03445559.

Clinical Trial Protocol for a Randomized Trial of Community Health Worker-led Decision Coaching to Promote Shared Decision-making on Prostate Cancer Screening Among Black Male Patients and Their Providers.

We propose a randomized controlled trial to evaluate the effectiveness of a community health worker-led decision-coaching program to facilitate shared decision-making for prostate cancer screening decisions by Black men at a primary care federally qualified health center.

Interaction between race and prostate cancer treatment benefit in the Veterans Health Administration.

BACKGROUND: Studies have demonstrated that Black men may undergo definitive prostate cancer (CaP) treatment less often than men of other races, but it is unclear whether they are avoiding overtreatment of low-risk disease or experiencing a reduction in appropriate care. The authors' aim was to assess the role of race as it relates to treatment benefit in access to CaP treatment in a single-payer population. METHODS: The authors used the Veterans Health Administration (VHA) Corporate Data Warehouse to perform a retrospective cohort study of veterans diagnosed with low- or intermediate-risk CaP between 2011 and 2017. RESULTS: The authors identified 35,427 men with incident low- or intermediate-risk CaP. When they controlled for covariates, Black men had 1.05 times the odds of receiving treatment in comparison with non-Black men (P < .001), and high-treatment-benefit men had 1.4 times the odds of receiving treatment in comparison with those in the low-treatment-benefit group (P < .001). The interaction of race and treatment benefit was significant, with Black men in the high-treatment-benefit category less likely to receive treatment than non-Black men in the same treatment category (odds ratio, 0.89; P < .001). CONCLUSIONS: Although race does appear to influence the receipt of definitive treatment in the VHA, this relationship varies in the context of the patient's treatment benefit, with Black men receiving less definitive treatment in high-benefit situations. The influence of patient race at high treatment benefit levels invites further investigation into the driving forces behind this persistent disparity in this consequential group.

Randomized trial of community health worker-led decision coaching to promote shared decision-making for prostate cancer screening among Black male patients and their providers.

BACKGROUND: Black men are disproportionately affected by prostate cancer, the most common non-cutaneous malignancy among men in the USA. The United States Preventive Services Task Force (USPSTF) encourages prostate-specific antigen (PSA) testing decisions to be based on shared decision-making (SDM) clinician professional judgment, and patient preferences. However, evidence suggests that SDM is underutilized in clinical practice, especially among the most vulnerable patients. The purpose of this study is to evaluate the efficacy of a community health worker (CHW)-led decision-coaching program to facilitate SDM for prostate cancer screening among Black men in the primary care setting, with the ultimate aim of improving/optimizing decision quality. METHODS: We proposed a CHW-led decision-coaching program to facilitate SDM for prostate cancer screening discussions in Black men at a primary care FQHC. This study enrolled Black men who were patients at the participating clinical site and up to 15 providers who cared for them. We estimated to recruit 228 participants, ages 40-69 to be randomized to either (1) a decision aid along with decision coaching on PSA screening from a CHW or (2) receiving a decision aid along with CHW-led interaction on modifying dietary and lifestyle to serve as an attention control. The independent randomization process was implemented within each provider and we controlled for age by dividing patients into two strata: 40-54 years and 55-69 years. This sample size sufficiently powered the detection differences in the primary study outcomes: knowledge, indicative of decision quality, and differences in PSA screening rates. Primary outcome measures for patients will be decision quality and decision regarding whether to undergo PSA screening. Primary outcome measures for providers will be acceptability and feasibility of the intervention. We will examine how decision coaching about prostate cancer screening impact patient-provider communication. These outcomes will be analyzed quantitatively through objective, validated scales and qualitatively through semi-structured, in-depth interviews, and thematic analysis of clinical encounters. Through a conceptual model combining elements of the Preventative Health Care Model (PHM) and Informed Decision-Making Model, we hypothesize that the prostate cancer screening decision coaching intervention will result in a preference-congruent decision and decisional satisfaction. We also hypothesize that this intervention will improve physician satisfaction with counseling patients about prostate cancer screening. DISCUSSION: Decision coaching is an evidence-based approach to improve decision quality in many clinical contexts, but its efficacy is incompletely explored for PSA screening among Black men in primary care. Our proposal to evaluate a CHW-led decision-coaching program for PSA screening has high potential for scalability and public health impact. Our results will determine the efficacy, cost-effectiveness, and sustainability of a CHW intervention in a community clinic setting in order to inform subsequent widespread dissemination, a critical research area highlighted by USPSTF. TRIAL REGISTRATION: The trial was registered prospectively with the National Institute of Health registry ( www.clinicaltrials.gov ), registration number NCT03726320 , on October 31, 2018.

The Association of Veterans' PSA Screening Rates With Changes in USPSTF Recommendations.

BACKGROUND: In 2012, the United States Preventative Services Task Force (USPSTF) formally recommended against all prostate-specific antigen (PSA) screening for prostate cancer. Our goal was to characterize PSA screening trends in the Veterans Health Administration (VA) before and after the USPSTF recommendation and to determine if PSA screening was more likely to be ordered based on a veteran's race or age. METHODS: Using the VA Corporate Data Warehouse, we created 10 annual groups of PSA-eligible men covering 2009-2018. We identified all PSA tests performed in the VA to determine yearly rates of PSA screening. All statistical tests were 2-sided. RESULTS: The overall rate of PSA testing in the VA decreased from 63.3% in 2009 to 51.2% in 2018 (P < .001). PSA screening rates varied markedly by age group during our study period, with men aged 70-80 years having the highest initial rate and greatest decline (70.6% in 2009 to 48.4% in 2018, P < .001). Men aged 55-69 years had a smaller decline (65.2% in 2009 to 58.9% in 2018, P < .001) whereas the youngest men, aged 40-54 years, had an increase in PSA screening (26.2% in 2009 to 37.8% in 2018, P < .001). CONCLUSIONS: In this analysis of PSA screening rates among veterans before and after the 2012 USPSTF recommendation against screening, we found that overall PSA screening decreased only modestly, continuing for more than one-half of the men in our study. Veterans of different races had similar screening rates, suggesting that VA care may minimize racial disparities. Veterans of varying ages experienced statistically significantly differences in PSA screening trends.

A Clinical Reminder Order Check Intervention to Improve Guideline-concordant Imaging Practices for Men With Prostate Cancer: A Pilot Study.

OBJECTIVE: To understand how to potentially improve inappropriate prostate cancer imaging rates we used National Comprehensive Cancer Network's guidelines to design and implement a Clinical Reminder Order Check (CROC) that alerts ordering providers of potentially inappropriate imaging orders in real-time based on patient features of men diagnosed with low-risk prostate cancer. METHODS: We implemented the CROC at VA New York Harbor Healthcare System from April 2, 2015 to November 15, 2017. We then used VA administrative claims from the VA's Corporate Data Warehouse to analyze imaging rates among men with low-risk prostate cancer at VA New York Harbor Healthcare System before and after CROC implementation. We also collected and cataloged provider responses in response to overriding the CROC in qualitative analysis. RESULTS FIFTY SEVEN PERCENT: (117/205) of Veterans before CROC installation and 73% (61/83) of Veterans post-intervention with low-risk prostate cancer received guideline-concordant care. CONCLUSION: While the decrease in inappropriate imaging during our study window was almost certainly due to many factors, a Computerized Patient Record System-based CROC intervention is likely associated with at least moderate improvement in guideline-concordant imaging practices for Veterans with low-risk prostate cancer.

Quantifying downstream impact of inappropriate staging imaging in a cohort of veterans with low- and intermediate-risk incident prostate cancer.

INTRODUCTION: According to current National Comprehensive Cancer Network guidelines, routine imagining for staging low-risk prostate cancer is not recommended. However, extensive overuse of guideline-discordant imaging continues to persist. Incidental findings are common on imaging and little is known about the optimal management. Rates of incidental findings vs. false positive diagnosis from inappropriate imaging are poorly understood and have yet to be quantified for low- and intermediate-risk prostate cancer patients. OBJECTIVE: To determine the frequency of positive radiologic findings in patients with low- and intermediate-risk prostate cancer during initial staging at VA New York Harbor Healthcare System. METHODS: We retrospectively reviewed all low- and intermediate-risk prostate cancer patients' medical records from the VA New York Harbor Healthcare System for diagnosis from 2005 to 2015. We reviewed each individual's prebiopsy prostate specific antigen (PSA), Gleason score, and clinical stage. We also determined if imaging obtained yielded a false positive, incidental finding, or if metastatic disease occurred within the 6 months following initial diagnosis. RESULTS: There were 414 men, who were classified as low- to intermediate-risk prostate cancer and underwent inappropriate staging imaging of 4,306 men diagnosed with prostate cancer. Of these 414 men, 178 (43%) had additional follow-up imaging for positive findings. We calculated an incidental finding rate of 10% and a false positive rate of 38% for patients. Five (1%) patients had metastatic disease. CONCLUSION: Despite guideline recommendations, imaging overuse remains an issue for low-intermediate-risk prostate cancer patients. The false positive rate found in this analysis is alarmingly high at 38%. This use of scans is burdensome to the healthcare system and patient. This study highlights the frequency of inappropriate imaging and its negative consequences.

Prostate cancer and social media.

The use of social media is increasing globally and is employed in a variety of ways in the prostate cancer community. In addition to their use in research, advocacy, and awareness campaigns, social media offer vast opportunities for education and networking for patients with prostate cancer and health-care professionals, and many educational resources and support networks are available to patients with prostate cancer and their caregivers. Despite the considerable potential for social media to be employed in the field of prostate cancer, concerns remain - particularly regarding the maintenance of patient confidentiality, variable information quality, and possible financial conflicts of interest. A number of professional societies have, therefore, issued guidance regarding social media use in medicine. Social media are used extensively in other cancer communities, particularly among patients with breast cancer, and both the quantity and type of information available are expected to grow in the future.

Designing a theory-based intervention to improve the guideline-concordant use of imaging to stage incident prostate cancer.

Among US men, most new prostate cancer cases are clinically localized and do not require imaging as part of staging workup according to guidelines. Two leading specialty societies promote stewardship of health resources by encouraging guideline-concordant care, thereby limiting inappropriate and obsolete imaging. However, imaging to stage low-risk prostate cancer remains high, as almost half of men with localized prostate cancer undergo wasteful imaging following diagnosis. We employed a theory-based approach, based on current evidence and data on existing practice patterns revealing that providers are the drivers to imaging decisions, to design an intervention to improve guideline -concordant prostate cancer staging imaging across populations. We conceptualized preliminary results using the theoretical domains framework and the behavior change wheel, frameworks used concurrently to investigate physicians' behaviors and intervention design in various clinical settings. Through these 2 frameworks, we designed a theory-based, physician-focused intervention to efficiently encourage guideline-concordant prostate cancer imaging, prostate cancer imaging stewardship (PCIS). Prostate cancer imaging stewardship consists of interventions (clinical order check, academic detailing, and audit and feedback) implemented at the individual, facility, and system level to enact provider behavior change by enabling facilitators and appealing to physician motivation.

Association Between Guideline-Discordant Prostate Cancer Imaging Rates and Health Care Service Among Veterans and Medicare Recipients.

Importance: Prostate cancer imaging rates appear to vary by health care setting. With the recent extension of the Veterans Access, Choice, and Accountability Act, the government has provided funds for veterans to seek care outside the Veterans Health Administration (VA). It is important to understand the difference in imaging rates and subsequent differences in patterns of care in the VA vs a traditional fee-for-service setting such as Medicare. Objective: To assess the association between prostate cancer imaging rates and a VA vs fee-for-service health care setting. Design, Setting, and Participants: This cohort study included data for men who received a diagnosis of prostate cancer from January 1, 2004, through March 31, 2008, that were collected from the VA Central Cancer Registry, linked to administrate claims and Medicare utilization records, and the Surveillance, Epidemiology, and End Results Program database. Three distinct nationally representative cohorts were constructed (use of VA only, use of Medicare only, and dual use of VA and Medicare). Men older than 85 years at diagnosis and men without high-risk features but missing any tumor risk characteristic (prostate-specific antigen, Gleason grade, or clinical stage) were excluded. Analysis of the data was completed from March 2016 to February 2018. Exposures: Patient utilization of different health care delivery systems. Main Outcomes and Measures: Rates of prostate cancer imaging were analyzed by health care setting (Medicare only, VA and Medicare, and VA only) among patients with low-risk prostate cancer and patients with high-risk prostate cancer. Results: Of 98 867 men with prostate cancer (77.4% white; mean [SD] age, 70.26 [7.48] years) in the study cohort, 57.3% were in the Medicare-only group, 14.5% in the VA and Medicare group, and 28.1% in the VA-only group. Among men with low-risk prostate cancer, the Medicare-only group had the highest rate of guideline-discordant imaging (52.5%), followed by the VA and Medicare group (50.9%) and the VA-only group (45.9%) (P < .001). Imaging rates for men with high-risk prostate cancer were not significantly different among the 3 groups. Multivariable analysis showed that individuals in the VA and Medicare group (risk ratio [RR], 0.87; 95% CI, 0.76-0.98) and VA-only group (RR, 0.79; 95% CI, 0.67-0.92) were less likely to receive guideline-discordant imaging than those in the Medicare-only group. Conclusions and Relevance: The results of this study suggest that patients with prostate cancer who use Medicare rather than the VA for health care could experience more utilization of health care services without an improvement in the quality of care.

Informational needs during active surveillance for prostate cancer: A qualitative study.

OBJECTIVE: To understand the informational needs during active surveillance (AS) for prostate cancer from the perspectives of patients and providers. METHODS: We conducted seven focus groups with 37 AS patients in two urban clinical settings, and 24 semi-structured interviews with a national sample of providers. Transcripts were analyzed using applied thematic analysis, and themes were organized using descriptive matrix analyses. RESULTS: We identified six themes related to informational needs during AS: 1) more information on prostate cancer (biopsy features, prognosis), 2) more information on active surveillance (difference from watchful waiting, testing protocol), 3) more information on alternative management options (complementary medicine, lifestyle modification), 4) greater variety of resources (multiple formats, targeting different audiences), 5) more social support and interaction, and 6) verified integrity of information (trusted, multidisciplinary and secure). CONCLUSIONS: Patients and providers described numerous drawbacks to existing prostate cancer resources and a variety of unmet needs including information on prognosis, AS testing protocols, and lifestyle modification. They also expressed a need for different types of resources, including interaction and unbiased information. PRACTICAL IMPLICATIONS: These results are useful to inform the design of future resources for men undergoing AS.

Twitter Activity Associated With U.S. News and World Report Reputation Scores for Urology Departments.

OBJECTIVE: To analyze the association between US urology department Twitter presence and U.S. News and World Report (USNWR) reputation scores, to examine the content, informational value, and intended audience of these platforms, and to identify objectives for Twitter use. MATERIALS AND METHODS: We identified Twitter accounts for urology departments scored in the 2016-2017 USNWR. Correlation coefficients were calculated between Twitter metrics (number of followers, following, tweets, and Klout influence scores) with USNWR reputation scores. We also performed a detailed content analysis of urology department tweets during a 6-month period to characterize the content. Finally, we distributed a survey to the urology department accounts via Twitter, inquiring who administers the content, and their objectives for Twitter use. RESULTS: Among 42 scored urology departments with Twitter accounts, the median number of followers, following, and tweets were 337, 193, and 115, respectively. All of these Twitter metrics had a statistically significant positive correlation with reputation scores (P <.05). Content analyses revealed that most tweets were about conferences, education, and publications, targeting the general public or urologic community. Survey results revealed that the primary reason for twitter use among urology departments was visibility and reputation, and urologists are considered the most important target audience. CONCLUSION: There is statistically significant correlation between Twitter activity and USNWR reputation scores for urology departments. Our results suggest that Twitter provides a novel mechanism for urology departments to communicate about academic and educational topics, and social media engagement can enhance reputation.
