Patterns of Care for Medicare Beneficiaries With Metastatic Prostate Cancer.

INTRODUCTION: Therapeutic options for men with metastatic prostate cancer have increased in the past decade. We studied recent treatment patterns for men with metastatic prostate cancer and how treatment patterns have changed over time. METHODS: Using the Surveillance, Epidemiology, and End Results‒Medicare database, we identified fee-for-service Medicare beneficiaries who either were diagnosed with metastatic prostate cancer or developed metastases following diagnosis, as indicated by the presence of claims with diagnoses codes for metastatic disease, between 2007 and 2017. We evaluated treatment patterns using claims. RESULTS: We identified 29,800 men with metastatic disease, of whom 4721 (18.8%) had metastatic disease at their initial diagnosis. The mean age was 77 years, and 77.9% of patients were non-Hispanic White. The proportion receiving antineoplastic agents within 3 years of the index date increased over time (from 9.7% in 2007 to 25.9% in 2017; P < .001). Opioid use within 3 years of prostate cancer diagnosis was stable during 2007 to 2013 (around 73%) but decreased through 2017 to 65.5% (P < .001). Patients diagnosed during 2015 to 2017 had longer median survival (32.6 months) compared to those diagnosed during 2007 to 2010 (26.6 months; P < .001). CONCLUSIONS: Most metastatic prostate cancer patients do not receive life-prolonging antineoplastic therapies. Improved adoption of effective cancer therapies when appropriate may increase length and quality of survival among metastatic prostate cancer patients.

Variation in State-Level Mammography Use, 2012 and 2020.

OBJECTIVES: Mammography is a screening tool for early detection of breast cancer. Uptake in screening use in states can be influenced by Medicaid coverage and eligibility policies, public health outreach efforts, and the Centers for Disease Control and Prevention-funded National Breast and Cervical Cancer Early Detection Program. We described state-specific mammography use in 2020 and changes as compared with 2012. METHODS: We estimated the proportion of women aged ≥40 years who reported receiving a mammogram in the past 2 years, by age group, state, and demographic and socioeconomic characteristics, using 2020 Behavioral Risk Factor Surveillance System data. We also compared 2020 state estimates with 2012 estimates. RESULTS: The proportion of women aged 50-74 years who received a mammogram in the past 2 years was 78.1% (95% CI, 77.4%-78.8%) in 2020. Across measures of socioeconomic status, mammography use was generally lower among women who did not have health insurance (52.0%; 95% CI, 48.3%-55.6%) than among those who did (79.9%; 95% CI, 79.3%-80.6%) and among those who had a usual source of care (49.4%; 95% CI, 46.1%-52.7%) than among those who did not (81.0%; 95% CI, 80.4%-81.7%). Among women aged 50-74 years, mammography use varied across states, from a low of 65.2% (95% CI, 61.4%-69.0%) in Wyoming to a high of 86.1% (95% CI, 83.8%-88.3%) in Massachusetts. Four states had significant increases in mammography use from 2012 to 2020, and 8 states had significant declines. CONCLUSION: Mammography use varied widely among states. Use of evidence-based interventions tailored to the needs of local populations and communities may help close gaps in the use of mammography.

Cost-Effectiveness Analysis of Screening for Pancreatic Cancer Among High-Risk Populations.

PURPOSE: We evaluated the potential cost-effectiveness of combined magnetic resonance imaging (MRI) and endoscopic ultrasound (EUS) screening for pancreatic ductal adenocarcinoma (PDAC) among populations at high risk for the disease. METHODS: We used a microsimulation model of the natural history of PDAC to estimate the lifetime health benefits, costs, and cost-effectiveness of PDAC screening among populations with specific genetic risk factors for PDAC, including BRCA1 and BRCA2, PALB2, ATM, Lynch syndrome, TP53, CDKN2A, and STK11. For each high-risk population, we simulated 29 screening strategies, defined by starting age and frequency. Screening included MRI with follow-up EUS in a subset of patients. Costs of tests were based on Medicare reimbursement for MRI, EUS, fine-needle aspiration biopsy, and pancreatectomy. Cancer-related cost by stage of disease and phase of treatment was based on the literature. For each high-risk population, we performed an incremental cost-effectiveness analysis, assuming a willingness-to-pay (WTP) threshold of $100,000 US dollars (USD) per quality-adjusted life year (QALY) gained. RESULTS: For men with relative risk (RR) 12.33 (CDKN2A) and RR 28 (STK11), annual screening was cost-effective, starting at age 55 and 40 years, respectively. For women, screening was only cost-effective for those with RR 28 (STK11), with annual screening starting at age 45 years. CONCLUSION: Combined MRI/EUS screening may be a cost-effective approach for the highest-risk populations (among mutations considered, those with RR >12). However, for those with moderate risk (RR, 5-12), screening would only be cost-effective at higher WTP thresholds (eg, $200K USD/QALY) or with once-only screening.

Hospital ownership and admission rates from the emergency department, evidence from Florida.

OBJECTIVE: In light of Department of Justice investigations of for-profit chains for over-admitting patients, we sought to evaluate whether for-profit hospitals are more likely to admit patients from the emergency department. DATA SOURCES: We used statewide visit-level inpatient and emergency department records from Florida's Agency for Healthcare Administration for 2007-2019. STUDY DESIGN: We calculated differences in admission rates between for-profit and other hospitals, adjusting for patient and hospital characteristics. We also estimated instrumental variables models using differential distance to a for-profit hospital as an instrument. DATA COLLECTION/EXTRACTION METHODS: Our main analysis focuses on patients ages 65 and older treated in hospitals that primarily serve adults. PRINCIPAL FINDINGS: Adjusted admission rates among patients ages 65 and older were 7.1 percentage points (95% CI: 5.1-9.1) higher at for-profit hospitals in 2019 (or 18.8% of the sample mean of 37.8%). Differences in admission rates have remained constant since 2009. CONCLUSION: Our results are consistent with allegations that for-profit hospitals maintain lower admission thresholds to increase occupancy levels.

Health-related quality of life among prostate cancer survivors with metastatic disease and non-metastatic disease and men without a cancer history in the USA.

BACKGROUND: Few studies have comprehensively compared health-related quality of life (HRQoL) between metastatic prostate cancer survivors, survivors with non-metastatic disease, and men without a cancer history. METHODS: We used the Surveillance, Epidemiology, and End Results-Medicare Health Outcomes Survey (SEER-MHOS) data linkage to identify men aged ≥ 65 years enrolled in Medicare Advantage (MA) plans. Prostate cancer survivors were diagnosed between 1988 and 2017 and completed MHOS surveys between 1998 and 2019. We analyzed data from 752 metastatic prostate cancer survivors (1040 survey records), 19,583 localized or regional prostate cancer survivors (non-metastatic; 30,121 survey records), and 784,305 men aged ≥ 65 years without a cancer history in the same SEER regions (1.15 million survey records). We used clustered linear regressions to compare HRQoL measures at the person-level using the Veterans RAND 12 Item Health Survey (VR-12) T-scores for general health and physical and mental component summaries. RESULTS: Compared to men without a cancer history, prostate cancer survivors were older, more likely to be married, and had higher socioeconomic status. Compared to men without a cancer history, metastatic prostate cancer survivors reported lower general health (T-score differences [95% confidence interval]: - 6.26, [- 7.14, - 5.38], p < .001), physical health (- 4.33, [- 5.18, - 3.48], p < .001), and mental health (- 2.64, [- 3.40, - 1.88], p < .001) component summaries. Results were similar for other VR-12 T-scores. In contrast, non-metastatic prostate cancer survivors reported similar VR-12 T-scores as men without a cancer history. Further analyses comparing metastatic and non-metastatic prostate cancer survivors support these findings. CONCLUSION: Interventions to improve health-related quality of life for men diagnosed with metastatic prostate cancer merit additional investigation. IMPLICATIONS FOR CANCER SURVIVORS: Interventions to improve health-related quality of life for metastatic prostate cancer survivors merit additional investigation.

The cost burden of metastatic prostate cancer in the US populations covered by employer-sponsored health insurance.

BACKGROUND: Recent advancements in the clinical management of metastatic prostate cancer include several costly therapies and diagnostic tests. The objective of this study was to provide updated information on the cost to payers attributable to metastatic prostate cancer among men aged 18 to 64 years with employer-sponsored health plans and men aged 18 years or older covered by employer-sponsored Medicare supplement insurance. METHODS: By using Merative MarketScan commercial and Medicare supplemental data for 2009-2019, the authors calculated differences in spending between men with metastatic prostate cancer and their matched, prostate cancer-free controls, adjusting for age, enrollment length, comorbidities, and inflation to 2019 US dollars. RESULTS: The authors compared 9011 patients who had metastatic prostate cancer and were covered by commercial insurance plans with a group of 44,934 matched controls and also compared 17,899 patients who had metastatic prostate cancer and were covered by employer-sponsored Medicare supplement plans with a group of 87,884 matched controls. The mean age of patients with metastatic prostate cancer was 58.5 years in the commercial samples and 77.8 years in the Medicare supplement samples. Annual spending attributable to metastatic prostate cancer was $55,949 per person-year (95% confidence interval [CI], $54,074-$57,825 per person-year) in the commercial population and $43,682 per person-year (95% CI, $42,022-$45,342 per person-year) in the population covered by Medicare supplement plans, both in 2019 US dollars. CONCLUSIONS: The cost burden attributable to metastatic prostate cancer exceeds $55,000 per person-year among men with employer-sponsored health insurance and $43,000 among those covered by employer-sponsored Medicare supplement plans. These estimates can improve the precision of value assessments of clinical and policy approaches to the prevention, screening, and treatment of prostate cancer in the United States.

Employment and Labor Force Participation Among Prostate Cancer Survivors.

INTRODUCTION: Diagnosis and treatment of cancer may impair patients' ability to continue to work. We assessed the impact of a prior prostate cancer diagnosis on employment and labor force participation. METHODS: Using the National Health Interview Surveys for 2010 to 2018, we identified sample adults previously diagnosed with prostate cancer aged <65 years (prostate cancer survivors) who were currently or previously employed. We matched each prostate survivor to comparison sample adults based on age, race/ethnicity, education level, and survey year. We compared employment-related outcomes between prostate cancer survivors and comparison males, overall and as a function of time since diagnosis, and other respondent characteristics. RESULTS: The final sample had 571 prostate cancer survivors and 2,849 matched comparison males. The proportions of survivors and comparison males who were employed (ie, worked for pay in the week prior to the survey) were similar (60.4% and 60.6%; adjusted difference 0.6 [95% CI: -5.2 to 6.3]), as were labor force participation rates (67.3% vs 67.3%; adjusted difference 0.7 [95% CI: -4.7 to 6.1]). Survivors were slightly more likely to be not working due to disability (16.7% vs 13.3%; adjusted difference 2.7 [95% CI: -1.2 to 6.5]), though the difference was not significant. Survivors had more bed days than comparison males (8.0 vs 5.7; adjusted difference 2.8 [95% CI: 2.0 to 3.6]) and missed more workdays (7.4 vs 3.3; adjusted difference 4.5 [95% CI: 3.6 to 5.3]). CONCLUSIONS: Employment rates were similar between prostate cancer survivors and matched comparison males, though survivors missed work more often.

The Cost of Metastatic Prostate Cancer in the United States.

INTRODUCTION: We sought to estimate per patient and annual aggregate health care costs related to metastatic prostate cancer. METHODS: Using the Surveillance, Epidemiology, and End Results-Medicare database, we identified fee-for-service Medicare beneficiaries ages 66 and older diagnosed with metastatic prostate cancer or claims with diagnosis codes for metastatic disease (indicating tumor progression following diagnosis) between 2007 and 2017. We measured annual health care costs and compared costs between cases and a sample of beneficiaries without prostate cancer. RESULTS: We estimate that per-patient annual costs attributable to metastatic prostate cancer are $31,427 (95% CI: $31,219-$31,635; 2019 dollars). Annual attributable costs rose over time, from $28,311 (95% CI: $28,047-$28,575) in 2007-2013 to $37,055 (95% CI: $36,716-$37,394) in 2014-2017. In aggregate, health costs attributable to metastatic prostate cancer are $5.2 to $8.2 billion per year. CONCLUSIONS: The per patient annual health care costs attributable to metastatic prostate cancer are substantial and have increased over time, corresponding to the approval of new oral therapies used in treating metastatic prostate cancer.

Quality of life and functional limitations in persons with epilepsy.

OBJECTIVE: Epilepsy can reduce quality of life (QOL), functionality, and social participation, but these effects have not been adequately quantified in large, population-based, controlled studies. We sought to evaluate the impact of epilepsy on patients' QOL and employment outcomes. METHODS: In this cross-sectional study we used nationally representative, pooled data from the Medical Expenditure Panel Survey (MEPS) household component files for 2010-2018. MEPS is a population-based survey of U.S. community-dwelling persons. We included respondents with condition file records for epilepsy. We also analyzed respondents with records for seizure. The primary outcomes were short form-12 physical and mental health scores. Secondary outcomes included self-rated health status, employment status, educational attainment, school/household/work limitations, and missed workdays. We compared these outcomes between persons with epilepsy (PWE) and age- and gender-matched controls. RESULTS: We identified 1078 people with epilepsy, 2344 seizure cases, and 3422 cases of either condition (persons with epilepsy and/or seizures). Epilepsy was associated with a decrease of - 4.0 (95% CI: -5.1 to -2.8) points in SF-12 physical health scores and - 3.1 (95% CI: -4.2 to -1.9) in SF-12 mental health scores. Epilepsy was also associated with decreases in the likelihood of reporting good/very good/excellent health status (-13.3 [95% CI: -16.1 to -10.4] percentage points). Epilepsy was also associated with adverse employment-related outcomes. Specifically, PWE were 17.9 (95% CI: 14.3-21.4) percentage points more likely to report that they had work or household limitations. The associations between outcomes and epilepsy were, in most cases, larger than those between outcomes and other common, chronic conditions. SIGNIFICANCE: Epilepsy is associated with worse quality of life and employment-related outcomes. Interventions should aim to improve functioning and patients' ability to maintain employment.

Cancer Survivorship and Supportive Care Economics Research: Current Challenges and Next Steps.

BACKGROUND: Rapid growth in the number of cancer survivors raises numerous questions about health and economic outcomes among survivors along with their families, caregivers, and employers. Health economics theory and methods can contribute to many open questions to improve survivorship. METHODS: In this paper, we review key areas where more research is needed and describe strategies for improving data infrastructure, research funding, and capacity building to strengthen survivorship health economics research. CONCLUSIONS: Health economics has broadened an understanding of key supply- and demand-side factors that promote cancer survivorship. To ensure necessary research in survivorship health economics moving forward, we recommend dedicated funding, inclusion of health economics outcomes in primary data collection, and investments in secondary data sets.

The impact of government-mandated shared decision-making for implantable defibrillators: A natural experiment.

BACKGROUND: In 2018, the Centers for Medicare and Medicaid Services (CMS) mandated that patients considering implantation of an implantable cardioverter-defibrillator (ICD) for primary prevention of sudden cardiac death undergo shared decision-making (SDM) using a decision-aid. OBJECTIVE: To observe the impact of the CMS's mandate on core measures of SDM using a natural experiment. RESEARCH DESIGN, SUBJECTS, AND MEASURES: Patients who underwent implantation of a primary prevention ICD within the Emory Healthcare system between 2017-2019 (pre and post SDM mandate) were surveyed. Survey domains included knowledge about the ICD, decisional conflict, values-choice concordance, and engagement in decision-making. Patients who had an ICD implant after the mandate were also asked about their views of the decision aid (DA). Responses of patients who had ICD implanted prior to the mandate were compared to those after the mandate using either Student t test or Chi-Squared tests. RESULTS: Of 101 patients who completed the survey, 45 had an ICD placed before the mandate and 56 had an ICD placed after. There were no major differences between knowledge, decisional conflict, values choice concordance, or patient engagement. Compared to patients with ICDs placed before the mandate, patients with ICDs after the mandate were more likely to subjectively feel more informed about the benefits of the procedure but were less likely to be able to correctly identify the frequency of complications. CONCLUSIONS: Policy effects to promote SDM that solely focus on a decision-aid may not substantively impact patient centered care.

Disparities in magnetic resonance imaging of the prostate for traditionally underserved patients with prostate cancer.

BACKGROUND: Prebiopsy magnetic resonance imaging (MRI) of the prostate improves detection of significant tumors, while decreasing detection of less-aggressive tumors. Therefore, its use has been increasing over time. In this study, the use of prebiopsy MRI among Medicare beneficiaries with prostate cancer was examined. It was hypothesized that patients of color and those in isolated areas would be less likely to undergo this approach for cancer detection. METHODS: Using cancer registry data from the Surveillance, Epidemiology, and End Results (SEER) program linked to billing claims for fee-for-service Medicare beneficiaries, men with nonmetastatic prostate cancer were identified from 2010 through 2015 with prostate-specific antigen (PSA) <30 ng/mL. Outcome was prebiopsy MRI of the prostate performed within 6 months before diagnosis (ie, Current Procedural Terminology 72197). Exposures were patient race/ethnicity and rural/urban status. Multivariable regression estimated the odds of prebiopsy prostate MRI. Post hoc analyses examined associations with the registry-level proportion of non-Hispanic Black patients and MRI use, as well as disparities in MRI use in registries with data on more frequent use of prostate MRI. RESULTS: There were 50,719 men identified with prostate cancer (mean age, 72.1 years). Overall, 964 men (1.9% of cohort) had a prebiopsy MRI. Eighty percent of patients with prebiopsy MRI lived in California, New Jersey, or Connecticut. Non-Hispanic Black men (0.6% vs 2.1% non-Hispanic White; odds ratio [OR], 0.28; 95% CI, 0.19-0.40) and men in less urban areas (1.1% vs 2.2% large metro; OR, 0.65; 95% CI, 0.44-0.97) were less likely to have prebiopsy MRI of the prostate. CONCLUSIONS: Non-Hispanic Black patients with prostate cancer and those in less urban areas were less likely to have prebiopsy MRI of the prostate during its initial adoption as a tool for improving prostate cancer detection.

The value of new drugs for advanced prostate cancer.

BACKGROUND: The US Food and Drug Administration has recently approved a number of new cancer drugs. The clinical trials that serve as the basis for new cancer drug approvals may not reflect how the drugs will perform in routine practice and do not measure the impact of the drugs on spending. The authors sought to evaluate the real-world effectiveness and value of drugs recently approved for advanced prostate cancer. METHODS: Using Surveillance, Epidemiology, and End Results-Medicare data, the authors identified fee-for-service Medicare beneficiaries aged 65 years or older who began treatment with a drug approved for metastatic castration-resistant prostate cancer in 2007-2009, when only 1 drug was approved for metastatic castration-resistant prostate cancer, and in 2014-2016, when 5 additional drugs were approved. They calculated life expectancy and lifetime medical costs (ie, Medicare reimbursements) for each group. RESULTS: Between 2007-2009 and 2014-2016, life expectancy increased by 12.6 months. Lifetime medical costs increased by $87,000. The incremental cost per life-year gained was $83,000. CONCLUSION: The release of 5 new drugs coincided with increases in survival rates and spending. This study's estimates indicate that the new drugs collectively were cost-effective.

Medicare fee reductions and the overuse of intensity-modulated radiotherapy.

OBJECTIVE: To estimate the impact of a large Medicare fee reduction for intensity-modulated radiation therapy (IMRT) on its use in prostate and breast cancer patients. DATA SOURCES/STUDY SETTING: SEER-Medicare. STUDY DESIGN: We compared trends in the use of IMRT between patients treated in practices directly affected by fee reductions (for prostate cancer, men treated in urology practices that own IMRT equipment; for breast cancer, women treated in freestanding radiotherapy clinics) and patients treated in other types of practices. DATA COLLECTION/EXTRACTION METHODS: We identified breast and prostate cancer patients receiving IMRT using outpatient and physician office claims. We classified urology practices based on whether they billed for IMRT and radiotherapy clinics based on whether they were reimbursed under the Physician Fee Schedule. PRINCIPAL FINDINGS: Between 2006 and 2015 the payment for IMRT delivered in freestanding clinics and physician offices declined by $367 (-54.7%). However, the use of IMRT increased in physician practices subject to payment cuts, both in absolute terms and relative to use in practices unaffected by the payment cut. Use of IMRT in prostate cancer patients treated at urology practices that own IMRT equipment increased by 9.1 (95% CI: 2.0-16.2) percentage points between 2005 and 2016 relative to use in patients treated at other urology practices. Use of IMRT in breast cancer patients treated at freestanding radiotherapy centers increased by 7.5 (95% CI: -5.1 to 20.1) percentage points relative to use in patients treated at hospital-based centers. CONCLUSIONS: A steep decline in IMRT fees did not decrease IMRT use over the period from 2006 to 2015, though use has declined since 2010.

Shared Decision-Making for Implantable Cardioverter-Defibrillators: Policy Goals, Metrics, and Challenges.

Shared decision-making has become a new focus of health policy. Though its core elements are largely agreed upon, there is little consensus regarding which outcomes to prioritize for policy-mandated shared decision-making.

Deterrence effects of antifraud and abuse enforcement in health care.

Estimates of the benefits of antifraud enforcement in health care typically focus on direct monetary damages. Deterrence effects are acknowledged but unquantified. We evaluate the impact of a Department of Justice investigation of hospitals accused of billing Medicare for unnecessary implantable cardiac defibrillator (ICD) procedures on their use. Using 100 % inpatient and outpatient procedure data from Florida, we estimate that the investigation caused a 22 % decline in ICD implantations. The present value of savings nationally over a 10 year period is $2.7 billion, nearly 10 times larger than the $280 million in settlements the Department of Justice recovered from hospitals. The investigation had a large and long-lasting effect on physician behavior, indicating the utility of antifraud enforcement as a tool for reducing wasteful medical care.

Trends in the use of active surveillance and treatments in Medicare beneficiaries diagnosed with localized prostate cancer.

BACKGROUND: The treatment for men diagnosed with localized prostate cancer has changed over time given the increased attention to the harms associated with over-diagnosis and the development of protocols for active surveillance. METHODS: We examined trends in the treatment of men diagnosed with localized prostate cancer between 2004 and 2015, using the most recently available data from Surveillance, Epidemiology, and End Results Program (SEER)-Medicare. Patients were stratified by Gleason score, age, and race groups. RESULTS: The use of active surveillance increased from 22% in 2004-2005 to 50% in 2014-2015 for patients with a Gleason score of 6 or below and increased from 9% in 2004-2005 to 13% in 2014-2015 for patients with a Gleason score of 7 or above. Patients with a Gleason score of 7 or above had increased use of intensity-modulated radiation therapy and prostatectomy, especially among patients aged 75 years and older. Among patients with a Gleason score of 6 or below non-Hispanic black men were less likely to undergo active surveillance than non-Hispanic white men. CONCLUSIONS: There has been a large increase in the use of active surveillance among men with a Gleason score of 6 or below. However, non-Hispanic black men with a Gleason score of 6 or below are less likely to receive active surveillance.
