Objective: To test the feasibility of using the National Health Interview Survey (NHIS) to identify children with chronic illness through a noncategorical approach, as exemplified by the Children with Special Health Care Needs (CSHCN) screener. The ability to use the NHIS to identify CSHCN will permit analyses of the effects of welfare reform and public insurance eligibility expansions during the late 1990s on CSHCN.Data Sources: The NHIS from 1997, 1999, and 2000. The NHIS is an ongoing household survey representative of the civilian, noninstitutionalized population of the United States.Study Design: Survey items were selected from the NHIS and thresholds designated to replicate the content and logic of the CSHCN screener. The screener asks explicit questions concerning an elevated need for, or use of health care services, and about limitations in activity, both caused by a chronic health condition. The algorithm created was applied to the pooled 1999-2000 NHIS to generate national prevalence estimates. Multivariate logistic regression was estimated to determine the effect of having particular demographic characteristics on the likelihood of being identified as CSHCN. Log odds ratios were compared to those from earlier NHIS-based estimates and from a pretest of the CSHCN screener.Principal Findings: An estimated 12 percent of noninstitutionalized children aged 0 through 17 have a chronic condition that results in elevated service use or limitations in normal activity. This estimate is sensitive to inclusion of children with a broader array of less serious or shorter-term conditions. The estimated effects of child characteristics on the likelihood of being identified as having special health needs are similar but not identical to other algorithms that have been used to identify CSHCN.Conclusions: It is feasible to use existing questions in the NHIS to identify a population of CSHCN that is substantially similar to children identified through other algorithms or through use of a screening instrument imbedded in a household survey. The availability of this algorithm will permit use of the NHIS for important analyses of the effects of welfare reform and public insurance expansions on children with special health care needs.

Introduction: In the last decade, melanoma treatment has improved significantly. However, data on population-level treatment utilization and survival trends among older patients is limited. This study aimed to analyze trends in systemic anticancer therapy (Rx), including the uptake of immune checkpoint inhibitors (ICIs), in conjunction with trends in cause-specific survival among older patients (66+) diagnosed with advanced melanoma (2008-2019)., Methods: We used the Surveillance, Epidemiology, and End Results (SEER)-Medicare Condensed Resource to assess any Rx utilization among patients first diagnosed with advanced melanoma in 2008-2010, 2011-2014, and 2015-2019, stratified by stage, and type of first-line Rx among patients receiving Rx. The SEER dataset was used to evaluate trends in cause-specific survival by year of diagnosis., Results: Rx utilization (any type) almost doubled, from 28.6% (2008-2010) to 55.4% (2015-2019) for stage 3 melanoma, and from 35.5% to 68.0% for stage 4 melanoma. In 2008-2010, the standard first-line treatment was cytokines/cytotoxic chemotherapy/other. By 2015-2019, only 5.1% (stage 3) and <3.6% (stage 4) of patients receiving Rx received these agents, as ICIs emerged as the dominant treatment. Both 1-year and 5-year cause-specific survival significantly improved since 2010 for stage 4 and since 2013 for stage 3., Conclusions: This study shows a significant rise in Rx utilization and a rapid transition from cytokines/cytotoxic chemotherapy to ICIs, reflecting a rapid uptake of highly effective treatment in a previously challenging disease with limited options before 2011. The documented survival improvement aligns with the adoption of these novel treatments, underscoring their significant impact on real-world patient outcomes., (© 2024 The Author(s).

Background: A cancer diagnosis may have deleterious effects on health-related quality of life (HRQOL) as adults age. This study examined differences in HRQOL between cancer and matched noncancer Medicare beneficiaries over 65, within and across two time periods., Methods: We used novel matching methods on data from the Surveillance, Epidemiology and End Results (SEER)-Medicare Health Outcomes Survey (MHOS) data resource. We matched SEER-MHOS respondents with cancer from a recent period (2015-2019) to respondents with cancer from an earlier period (2008-2012). We then matched these two cohorts, without replacement, to contemporary cohorts without cancer diagnoses. We estimated Veteran's RAND 12-Item Short Form Survey Physical Component Summary (PCS) and Mental Component Summary (MCS) scores for all cohorts., Results: Our analysis found significantly higher mean MCS scores in the recent period for those with cancer relative to the recent noncancer control group. Breast and lung cancer presented positive and statistically significant trends. We found statistically insignificant differences in PCS scores between the two time periods. No cancer sites had different PCS scores over time compared with the comparison group., Conclusions: Mental health for those with cancer improved more between 2008 and 2019 than a matched noncancer comparison group. Physical health remained stable across time. These findings highlight the importance of including a matched noncancer group when evaluating HRQOL outcomes., Impact: SEER-MHOS respondents with cancer report stable PCS scores across 15 years of data and higher MCS scores relative to noncancer controls., (©2024 American Association for Cancer Research.)

Purpose: This study assessed the prevalence of specific major adverse financial events (AFEs)-bankruptcies, liens, and evictions-before a cancer diagnosis and their association with later-stage cancer at diagnosis., Methods: Patients age 20-69 years diagnosed with cancer during 2014-2015 were identified from the Seattle, Louisiana, and Georgia SEER population-based cancer registries. Registry data were linked with LexisNexis consumer data to identify patients with a history of court-documented AFEs before cancer diagnosis. The association of AFEs and later-stage cancer diagnoses (stages III/IV) was assessed using separate sex-specific multivariable logistic regression., Results: Among 101,649 patients with cancer linked to LexisNexis data, 36,791 (36.2%) had a major AFE reported before diagnosis. The mean and median timing of the AFE closest to diagnosis were 93 and 77 months, respectively. AFEs were most common among non-Hispanic Black, unmarried, and low-income patients. Individuals with previous AFEs were more likely to be diagnosed with later-stage cancer than individuals with no AFE (males-odds ratio [OR], 1.09 [95% CI, 1.03 to 1.14]; P < .001; females-OR, 1.18 [95% CI, 1.13 to 1.24]; P < .0001) after adjusting for age, race, marital status, income, registry, and cancer type. Associations between AFEs prediagnosis and later-stage disease did not vary by AFE timing., Conclusion: One third of newly diagnosed patients with cancer had a major AFE before their diagnosis. Patients with AFEs were more likely to have later-stage diagnosis, even accounting for traditional measures of socioeconomic status that influence the stage at diagnosis. The prevalence of prediagnosis AFEs underscores financial vulnerability of patients with cancer before their diagnosis, before any subsequent financial burden associated with cancer treatment.

Background: Cancer registry-based "primary payer at diagnosis" (PPDx) data are commonly used to evaluate the effect of insurance on cancer care outcomes, yet little is known about how well they capture Medicaid or Medicare enrollment., Methods: We linked the National Cancer Institute's Surveillance, Epidemiology, and End Results registry data to monthly Centers for Medicare and Medicaid Services (CMS) Medicaid and Medicare enrollment records, state-year Medicaid policy, and managed care enrollment. We selected adults aged 19-64 years diagnosed between 2007 and 2011. We used bivariate analyses to compare PPDx to CMS enrollment at diagnosis month and assessed underreporting rates by patient characteristics and state-year policy., Results: PPDx reported 7.8% Medicare and 10.1% Medicaid, whereas CMS enrollment indicated 5.5% Medicare, 10.4% Medicaid, and 3.4% dual Medicare-Medicaid (N = 896,031). Positive predictive values for PPDx assignment to Medicaid and Medicare were 65.3% and 75.4%, with false negative rates of 52.0% and 33.8%, respectively. Medicaid underreporting was higher in low (56.5%) versus high (50.8%) poverty areas, for males (56.1%) versus females (48.9%), for Medicaid poverty expansion or waiver enrolled (63.8%) versus cash assistance-related eligibility (47.3%), and in states with large managed care enrollment (all P < 0.001). If Medicaid and Medicare enrollment data were used to edit PPDx, 12.0% of persons would switch primary payer assignment., Conclusions: Registry-reported PPDx fails to fully capture Medicaid and Medicare enrollment, which may result in biased estimates of insurance-related policy impacts. Enhancement with objective enrollment data could reduce measurement error and bias in estimates necessary to support policy assessment., Competing Interests: The authors declare no conflict of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Understanding cancer survivors' health insurance decision-making is needed to improve insurance choice, potentially resulting in reduced financial hardship., Methods: This explanatory mixed methods study assessed health insurance decision-making in cancer survivors. Health Insurance Literacy Measure (HILM) captured HIL. Quantitative eye-tracking data collected from two simulated health insurance plan choice sets gauged dwell time (seconds), or interest, in benefits. Dwell time differences by HIL were estimated using adjusted linear models. Qualitative interviews explored survivors' insurance decision-making choices., Results: Cancer survivors (N = 80; 38% breast cancer) had a median age of 43 at diagnosis (IQR 34-52). When comparing traditional and high-deductible health plans, survivors were most interested in drug costs (median dwell time 58 s, IQR 34-109). When comparing health maintenance organization and preferred provider organization plans, survivors were most interested in test/imaging costs (40s, IQR 14-67). Survivors with low versus high HIL had more interest in deductible (β = 19 s, 95% CI 2-38) and hospitalization costs (β = 14 s, 95% CI 1-27) in adjusted models. Survivors with low versus high HIL more often ranked out-of-pocket (OOP) maximums and coinsurance as the most important and confusing benefits, respectively. Interviews (n = 20) revealed survivors felt alone "to do their own research" about insurance choices. OOP maximums were cited as the deciding factor since it is "how much money is going to be taken out of my pocket." Coinsurance was considered "rather than a benefit, it's a hindrance.", Conclusion: Interventions to aid in health insurance understanding and choice are needed to optimize plan choice and potentially reduce cancer-related financial hardship., (© 2023 The Authors.

Importance: The COVID-19 pandemic has led to a reduction in routine in-person medical care; however, it is unknown whether there have been any changes in visit rates among patients with hematologic neoplasms., Objective: To examine associations between the COVID-19 pandemic and in-person visits and telemedicine use among patients undergoing active treatment for hematologic neoplasms., Design, Setting, and Participants: Data for this retrospective observational cohort study were obtained from a nationwide electronic health record-derived, deidentified database. Data for patients with hematologic neoplasms who had received at least 1 systemic line of therapy between March 1, 2016, and February 28, 2021, were included. Treatments were categorized into 3 types: oral therapy, outpatient infusions, and inpatient infusions. The data cutoff date was April 30, 2021, when study analyses were conducted., Main Outcomes and Measures: Monthly visit rates were calculated as the number of documented visits (telemedicine or in-person) per active patient per 30-day period. We used time-series forecasting methods on prepandemic data (March 2016 to February 2020) to estimate expected rates between March 1, 2020, and February 28, 2021 (if the pandemic had not occurred)., Results: This study included data for 24 261 patients, with a median age of 68 years (IQR, 60-75 years). A total of 6737 patients received oral therapy, 15 314 received outpatient infusions, and 8316 received inpatient infusions. More than half of patients were men (14 370 [58%]) and non-Hispanic White (16 309 [66%]). Early pandemic months (March to May 2020) demonstrated a significant 21% reduction (95% prediction interval [PI], 12%-27%) in in-person visit rates averaged across oral therapy and outpatient infusions. Reductions in in-person visit rates were also significant for all treatment types for multiple myeloma (oral therapy: 29% reduction; 95% PI, 21%-36%; P = .001; outpatient infusions: 11% reduction; 95% PI, 4%-17%; P = .002; inpatient infusions: 55% reduction; 95% PI, 27%-67%; P = .005), for oral therapy for chronic lymphocytic leukemia (28% reduction; 95% PI, 12%-39%; P = .003), and for outpatient infusions for mantle cell lymphoma (38% reduction; 95% PI, 6%-54%; P = .003) and chronic lymphocytic leukemia (20% reduction; 95% PI, 6%-31%; P = .002). Telemedicine visit rates were highest for patients receiving oral therapy, with greater use in the early pandemic months and a subsequent decrease in later months., Conclusions and Relevance: In this cohort study of patients with hematologic neoplasms, documented in-person visit rates for those receiving oral therapy and outpatient infusions significantly decreased during the early pandemic months but returned to close to projected rates in the later half of 2020. There were no statistically significant reductions in the overall in-person visit rate for patients receiving inpatient infusions. There was higher telemedicine use in the early pandemic months, followed by a decline, but use was persistent in the later half of 2020. Further studies are needed to ascertain associations between the COVID-19 pandemic and subsequent cancer outcomes and the evolution of telemedicine use for care delivery.

Introduction: Medicare decedents with cancer often receive intensive care during the last month of life; however, little information exists on longer end-of-life care trajectories., Materials and Methods: Using SEER-Medicare data, we selected older adults diagnosed with lung cancer between 2008 and 2013 who survived at least six months and died between 2008 and 2014. Each month we assessed claims to assign care categories ordered by intensity as follows: full-month inpatient/skilled nursing facility > cancer-directed therapy (CDT) only > concurrent CDT and symptom management and supportive care services (SMSCS) > SMSCS only > full-month hospice. We assigned each decedent to one of six trajectories: stable hospice, stable SMSCS, stable CDT with or without concurrent SMSCS, decreasing intensity, increasing intensity, and mixed. Multinomial logistic regression estimated associations between socio-demographics, calendar year, and area hospice use rates with end-of-life trajectory., Results: The sample (N = 24,342) was predominantly aged ≥75 years (59.4%) and non-Hispanic White (80.5%); 19.1% lived in healthcare referral regions where ≤50% of cancer decedents received hospice care. Overall, 6.5% were continuously hospice enrolled, 25.6% received SMSCS only, and 29.4% experienced decreasing intensity; 3.9% received CDT or concurrent care, while 8.7% experienced an increase in intensity. Higher healthcare referral region hospice rates were associated with decreasing end-of-life intensity; Black, non-Hispanic decedents had a higher risk of increasing intensity and mixed patterns., Discussion: Among older decedents with lung cancer, 62% had six-month end-of-life trajectories indicating low or decreasing intensity, but few received persistent CDT. Demographic characteristics, including race/ethnicity, and contextual measures, including area hospice use patterns, were associated with end-of-life trajectory., Competing Interests: Declaration of Competing Interest Dr. Davidoff consulted for Amgen, and she has a family member who received advisory board and consulting income from Celgene and Abbvie.

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 Author(s) 2022.

We reviewed current literature reviews regarding economics of cancer-related health care to identify focus areas and gaps. We searched PubMed for systematic and other reviews with the Medical Subject Headings "neoplasms" and "economics" published between January 1, 2010, and April 1, 2020, identifying 164 reviews. Review characteristics were abstracted and described. The majority (70.7%) of reviews focused on cost-effectiveness or cost-utility analyses. Few reviews addressed other types of cancer health economic studies. More than two-thirds of the reviews examined cancer treatments, followed by screening (15.9%) and survivorship or end-of-life (13.4%). The plurality of reviews (28.7%) cut across cancer site, followed by breast (20.7%), colorectal (11.6%), and gynecologic (8.5%) cancers. Specific topics addressed cancer screening modalities, novel therapies, pain management, or exercise interventions during survivorship. The results indicate that reviews do not regularly cover other phases of care or topics including financial hardship, policy, and measurement and methods., (Published by Oxford University Press 2022.

Background: The COVID-19 pandemic has led to delays in patients seeking care for life-threatening conditions; however, its impact on treatment patterns for patients with metastatic cancer is unknown. We assessed the COVID-19 pandemic's impact on time to treatment initiation (TTI) and treatment selection for patients newly diagnosed with metastatic solid cancer., Methods: We used an electronic health record-derived longitudinal database curated via technology-enabled abstraction to identify 14 136 US patients newly diagnosed with de novo or recurrent metastatic solid cancer between January 1 and July 31 in 2019 or 2020. Patients received care at approximately 280 predominantly community-based oncology practices. Controlled interrupted time series analyses assessed the impact of the COVID-19 pandemic period (April-July 2020) on TTI, defined as the number of days from metastatic diagnosis to receipt of first-line systemic therapy, and use of myelosuppressive therapy., Results: The adjusted probability of treatment within 30 days of diagnosis was similar across periods (January-March 2019 = 41.7%, 95% confidence interval [CI] = 32.2% to 51.1%; April-July 2019 = 42.6%, 95% CI = 32.4% to 52.7%; January-March 2020 = 44.5%, 95% CI = 30.4% to 58.6%; April-July 2020 = 46.8%, 95% CI= 34.6% to 59.0%; adjusted percentage-point difference-in-differences = 1.4%, 95% CI = -2.7% to 5.5%). Among 5962 patients who received first-line systemic therapy, there was no association between the pandemic period and use of myelosuppressive therapy (adjusted percentage-point difference-in-differences = 1.6%, 95% CI = -2.6% to 5.8%). There was no meaningful effect modification by cancer type, race, or age., Conclusions: Despite known pandemic-related delays in surveillance and diagnosis, the COVID-19 pandemic did not affect TTI or treatment selection for patients with metastatic solid cancers., (© The Author(s) 2021.

Acute promyelocytic leukemia (APL) is associated with a favorable long-term prognosis if appropriate treatment is initiated promptly. Outcomes in clinical trials and population-based registries vary; potential explanations include a delay in treatment and lower adherence to guideline-recommended therapy in real-world practice. We used the Vizient Clinical Data Base to describe demographic characteristics, baseline clinical characteristics, and treatment patterns in patients newly diagnosed with APL during the study period of April 2017 to March 2020. Baseline white blood cell count was used to assign risk status and assess treatment concordance with National Comprehensive Cancer Network guidelines. Logistic regression models examined adjusted associations between patient, hospital, disease characteristics, and adverse outcomes (in-hospital death or discharge to hospice). Among 1464 patients with APL, 205 (14.0%) experienced an adverse outcome. A substantial subset (20.6%) of patients did not receive guideline-concordant regimens. Odds of adverse outcomes increased with failure to receive guideline-concordant treatment (odds ratio [OR], 2.31; 95% confidence interval [CI], 1.43-3.75; P = .001), high-risk disease (OR, 2.48; 95% CI, 1.53-4.00; P < .001), and increasing age (≥60 years: OR, 11.13; 95% CI, 4.55-27.22; P < .001). Higher hospital acute myeloid leukemia (AML) patient volume was associated with lower odds of adverse outcome (OR, 0.44; 95% CI, 0.20-0.99 [for ≤50 vs >200 AML patients per year]; P = .046). In conclusion, in this large database analysis, 14.0% of patients newly diagnosed with APL died or were discharged to hospice. A substantial proportion of patients did not receive guideline-concordant therapy, potentially contributing to adverse outcomes., (© 2022 by The American Society of Hematology.

Background: There has been rapid integration of telehealth into care delivery during the COVID-19 pandemic. However, little is known about technology ownership, internet access and use for communication, and telehealth availability among cancer survivors, particularly those enrolled in Medicare., Objective: This study aims to identify sociodemographic associations with technology ownership, internet access and use for communication, and telehealth availability in a population-based sample of Medicare-enrolled cancer survivors., Methods: Data are from the Medicare Current Beneficiary Survey COVID-19 Summer 2020 Supplement administered between June 10 and July 15, 2020. Analyses were restricted to beneficiaries who reported a prior (nonskin) cancer diagnosis and a usual source of care (N=2044). Dichotomous outcomes included technology ownership, internet access, internet use for communication, and telehealth availability from providers. Sociodemographic correlates included sex, age, race/ethnicity, Medicare/Medicaid dual enrollment, rurality, census region, and self-reported comorbidities., Results: Over half (957/2044, 53%) of cancer survivors reported using the internet for communication purposes, and 62% (1218/2044) reported that their usual provider had telehealth services available. Using the internet for communication purposes was reported less frequently for rural compared to urban survivors (adjusted probability of 28% vs 46%; P<.001) and for Hispanic and Black survivors compared to non-Hispanic White survivors (29%, 31%, and 44%, respectively; all P<.01). Rural survivors reported lower telehealth availability (53% vs 63%; P<.001); no significant differences in telehealth availability were identified by race/ethnicity., Conclusions: During the COVID-19 pandemic, study findings highlight a complex digital divide among Medicare beneficiaries with a history of cancer related to device ownership necessary for telehealth, internet access and use for communication, and reports of providers having telehealth available. Multilevel approaches are needed to increase equitable telehealth availability and use for cancer survivors. Suggested strategies include increasing broadband internet access to providers and patients in at-risk communities, supporting telehealth implementation among providers that serve populations with known health disparities, raising awareness of providers' available telehealth services among patients, and screening for technology use and provision of telehealth-related technical assistance among older and historically underserved cancer survivors., (©Yuki Lama, Amy J Davidoff, Robin C Vanderpool, Roxanne E Jensen.

Aims: The glucose-driven enzymatic modification of myocardial proteins by the sugar moiety, β-N-acetylglucosamine (O-GlcNAc), is increased in pre-clinical models of diabetes, implicating protein O-GlcNAc modification in diabetes-induced heart failure. Our aim was to specifically examine cardiac manipulation of the two regulatory enzymes of this process on the cardiac phenotype, in the presence and absence of diabetes, utilising cardiac-targeted recombinant-adeno-associated viral-vector-6 (rAAV6)-mediated gene delivery., Methods and Results: In human myocardium, total protein O-GlcNAc modification was elevated in diabetic relative to non-diabetic patients, and correlated with left ventricular (LV) dysfunction. The impact of rAAV6-delivered O-GlcNAc transferase (rAAV6-OGT, facilitating protein O-GlcNAcylation), O-GlcNAcase (rAAV6-OGA, facilitating de-O-GlcNAcylation), and empty vector (null) were determined in non-diabetic and diabetic mice. In non-diabetic mice, rAAV6-OGT was sufficient to impair LV diastolic function and induce maladaptive cardiac remodelling, including cardiac fibrosis and increased Myh-7 and Nppa pro-hypertrophic gene expression, recapitulating characteristics of diabetic cardiomyopathy. In contrast, rAAV6-OGA (but not rAAV6-OGT) rescued LV diastolic function and adverse cardiac remodelling in diabetic mice. Molecular insights implicated impaired cardiac PI3K(p110α)-Akt signalling as a potential contributing mechanism to the detrimental consequences of rAAV6-OGT in vivo. In contrast, rAAV6-OGA preserved PI3K(p110α)-Akt signalling in diabetic mouse myocardium in vivo and prevented high glucose-induced impairments in mitochondrial respiration in human cardiomyocytes in vitro., Conclusion: Maladaptive protein O-GlcNAc modification is evident in human diabetic myocardium, and is a critical regulator of the diabetic heart phenotype. Selective targeting of cardiac protein O-GlcNAcylation to restore physiological O-GlcNAc balance may represent a novel therapeutic approach for diabetes-induced heart failure., (Published on behalf of the European Society of Cardiology.

Introduction: The choice of BCR-ABL1 tyrosine kinase inhibitors (TKI) for the first line of therapy (LOT) for chronic-phase chronic myeloid leukemia (CML) is tailored to disease risk and patient characteristics like comorbidities, which become more prevalent with age. However, contemporary evaluations of frontline TKI choice and the factors associated with TKI switching in this specific patient population are lacking., Methods: We sought to describe TKI use in older patients (age: 66-99 years) with CML in the United States. Using the Surveillance, Epidemiology, and End Results-Medicare-linked database, we identified 810 older (median age: 75 years, interquartile range: 70-80 years) patients diagnosed during 2007-2015., Results: Imatinib was the most common frontline TKI (63.1%) throughout the study period, but its utilization as such decreased from 76% in 2010 to 47% in 2015. Most patients (65.3%) used only one TKI, but 12.5% of the 281 patients who switched from frontline TKI received ⩾4 LOT. Among the 167 patients switching from frontline imatinib, 18.6% eventually returned to imatinib with nearly all as the third LOT, supporting its favorable safety profile and indicating that the initial switch from imatinib might have been premature. Older patients within our cohort, white patients and those with greater comorbidity were less likely to switch from frontline TKI. Diagnosis year, geographic region, and surrogates for socioeconomic status and healthcare access had no impact on TKI switching., Conclusion: As expected, our findings highlight the frequent use of imatinib as the treatment option for older CML patients despite the availability of second-generation TKIs., Competing Interests: Conflict of interest statement: A.M.Z. received research funding (institutional) from Celgene, Acceleron, Abbvie, Otsuka, Pfizer, Medimmune/AstraZeneca, Boehringer Ingelheim, Trovagene, Incyte, Takeda, and ADC Therapeutics.

Purpose: Eastern Cooperative Oncology Group performance status (ECOG PS) is an important predictor for receipt of treatment and overall survival (OS) but is often unreported in routine care. We developed a proxy for baseline ECOG PS using electronic health records (EHRs)., Methods: We analyzed patients who were diagnosed with advanced non-small cell lung cancer (aNSCLC), advanced bladder cancer (aBCa), and advanced melanoma (aMEL) between 2011 and 2018 and had a baseline (reported between diagnosis and treatment) ECOG PS in a real-world database. We used stepwise multivariable logistic regression to model associations between baseline ECOG PS good (<2) versus poor (≥2) and sociodemographic, clinical, and laboratory measures in each cancer type. Predictive accuracy of classifying ECOG PS was assessed. We tested the association between OS and observed and predicted ECOG PS., Results: In total, 20 697 aNSCLC patients, 2627 aBCa patients, and 2558 aMEL patients constituted the study population. Percentage of patients with poor ECOG PS ranged from 15.3% (aMEL) to 28.5% (aNSCLC). Poor ECOG PS was associated with more comorbid conditions, older age, lower body mass index, metastases, and abnormal laboratory indicators. Overall prediction accuracy using a 0.50 cutpoint was 73.3% for NSCLC, 73.8% for aBCa, and 85.4% for aMEL. The association of OS with ECOG PS was consistent between the observed and proxy measures., Conclusions: In the EHR-derived data, clinical, sociodemographic, and laboratory information were used to assign ECOG PS and enhance the use of real-world data in outcome studies., (© 2021 John Wiley & Sons Ltd.)

Background: Rather than early hospice enrollment, most Medicare beneficiaries receive "usual care" in the last months of life, outside of the hospice setting. While care intensity during the last weeks of life has been studied extensively, patterns of symptom management services (SMS) and/or cancer-directed therapies (CDT) received over a 6-month end-of-life period have not., Methods: This retrospective study used the Surveillance, Epidemiology, and End Results (SEER)-Medicare database to identify decedents diagnosed with lung cancer at age ≥ 66 years between January 2007 and December 2013 who survived ≥ 6 months from diagnosis. Medicare claims identified receipt of SMS and/or CDT. We created monthly indicators for care content (SMS-only, CDT-only, or both; otherwise full-month hospice or inpatient/skilled nursing). Multinomial logistic regression estimated associations between sociodemographics and comorbidity, with care content in the final month., Results: Between 6 and 1 months before death, full-month hospice and inpatient/skilled nursing increased; CDT decreased from 31.9 to 18.5%; SMS increased from 86.6 to 97.7%. Relative to full-month hospice, the percentage of patients receiving SMS-only was higher for males, unmarried, younger age, and higher comorbidity; the percentage receiving CDT was also higher for males, unmarried, and younger age, but decreased with increasing comorbidity and over calendar time., Conclusion: Among lung cancer decedents observed in the outpatient, nonhospice setting, SMS receipt increased and was nearly universal as death approached. CDT diminished dramatically over the end-of-life period. Associations between sociodemographic characteristics and care setting suggest differences in care preferences or access barriers. Claims represent an important resource for characterizing end-of-life care patterns.

Objectives: Racial disparities in cancer care and outcomes remain a societal challenge. Medicaid expansion through the Affordable Care Act was intended to improve health care access and equity. This study aimed to assess whether state Medicaid expansions were associated with a reduction in racial disparities in timely treatment among patients diagnosed with advanced cancer., Study Design: This difference-in-differences study analyzed deidentified electronic health record-derived data. Patients aged 18 to 64 years with advanced or metastatic cancers diagnosed between January 1, 2011, and January 31, 2019, and receiving systemic therapy were included., Methods: The primary end point was receipt of timely treatment, defined as first-line systemic therapy starting within 30 days after diagnosis of advanced or metastatic disease. Racial disparity was defined as adjusted percentage-point (PP) difference for Black vs White patients, adjusted for age, sex, practice setting, cancer type, stage, insurance marketplace, and area unemployment rate, with time and state fixed effects., Results: The study included 30,310 patients (12.3% Black race). Without Medicaid expansion, Black patients were less likely to receive timely treatment than White patients (43.7% vs 48.4%; adjusted difference, -4.8 PP; P < .001). With Medicaid expansion, this disparity was diminished and lost significance (49.7% vs 50.5%; adjusted difference, -0.8 PP; P = .605). The adjusted difference-in-differences estimate was a 3.9 PP reduction in racial disparity (95% CI, 0.1-7.7 PP; P = .045)., Conclusions: Medicaid expansion was associated with reduced Black-White racial disparities in receipt of timely systemic treatment for patients with advanced or metastatic cancers.

Objective: To describe medication utilization patterns by pediatric inpatients with cancer during their last week of life., Methods: This retrospective study used data from the Vizient Clinical Database/Resource Manager, a national compilation of clinical and resource use data from over 100 academic medical centers and affiliates. Patients (0-21 years) with malignancy who died during hospitalization (2010-2017) were included (N = 1659). Medications were categorized as opioid, benzodiazepine, gastrointestinal related, chemotherapy, anti-infectives, or vasopressors. Exposure to each group was ascertained for all patients at 1 week and 1 day prior to death. Factors associated with exposure were examined using generalized estimating equations, and summarized using adjusted odds ratios (aORs)., Results: Over the last week of life, there was increased use of opioids (76% to 82%, aOR = 1.55, P < .001) and benzodiazepines (53% to 66%, aOR = 1.36, P = .02), while gastrointestinal-related medication use decreased (92% to 89%, aOR = 0.69, P = .001). Patients had decreased exposure to chemotherapy (10% to 5%, aOR = 0.46, P < .001) and anti-infectives (82% to 73%, aOR = 0.41, P = .002). Vasopressor use increased as death approached (15% to 28%, aOR = 1.67, P = .04). Factors significantly associated with exposure varied with medication category, and included age, race, length of stay, malignancy type, death in the intensive care unit, history of hematopoietic stem cell transplant, and do-not-resuscitate status., Conclusion: During the week preceding death, administration of symptom management medications increased for children with cancer, but use was not universal. Potentially life-sustaining medications were often continued. Variability in utilization suggests differences in provider/family decision making that warrant further study to develop an evidence-based approach to end-of-life care., (© 2020 Wiley Periodicals LLC.)

Lay Summary: Cancer has substantial economic impacts for patients, their families and/or caregivers, employers, and the health care system. However, there is only limited understanding of how economic issues can affect access to cancer care services and the receipt of high-quality cancer care. Health economics research in cancer is particularly timely due to the large and increasing number of patients with cancer and cancer survivors, but there are many factors that may create barriers to performing cancer health economics research. This commentary has identified important topics and questions in cancer health economics research and will assist in the development of this critical field., (© 2020 American Cancer Society.)

Background: Pain is common among patients with cardiopulmonary conditions; however, there are increasing concerns, but limited research, regarding use of opioids for pain in patients with noncancer conditions. Objective: To compare patterns of opioid prescribing among older adults reporting pain with cardiopulmonary conditions and/or cancer. Design: Observational study using data from the Surveillance, Epidemiology, and End Results-Medicare Health Outcomes Survey resource linked to Medicare Part D prescription claims. Setting/Subjects: We identified patients who self-reported moderate-to-severe pain interference with daily activities. Patients were stratified by (1) self-reported history of cardiopulmonary conditions; (2) were within five years of cancer diagnosis; (3) had both conditions; or (4) neither. Measurements: We characterized opioid prescribing within 30 days of survey and one-year follow-up using logistic regression and Cox proportional hazard time-to-event analyses. Results: Of 10,516 patients with moderate-to-severe pain (1758 cardiopulmonary conditions, 3383 cancer, 2861 both, 2514 neither), 46% were aged ≥75 years, 65% were non-Hispanic white, and 10% non-Hispanic black. At survey, 1627 (15.5%) received opioids. Adjusted proportions of opioid use were lower for patients with cardiopulmonary conditions only (14%) compared with cancer only (17%; p  < 0.001) and both conditions (17%; p  < 0.001) but higher than patients with neither condition (13.1%; p  < 0.001). There was no difference in time to initiation of opioids at follow-up among patients with cardiopulmonary conditions only, relative to cancer only (adjusted hazard ratio 1.03; 95% confidence interval 0.88-1.21). Conclusions: Opioid use is lower among patients with pain and cardiopulmonary conditions relative to patients with cancer. Findings emphasize the importance of pain assessment and management for patients with cardiopulmonary conditions.

Objectives: Although survival after a cancer diagnosis has improved considerably over the past 20 years, little is known about trends in health-related quality-of-life (HRQOL) for older prostate, breast, and lung cancer survivors., Methods: Using a population-based registry with longitudinal patient reported outcomes (the National Cancer Institute Surveillance, Epidemiology and End Results database linked to Medicare Health Outcomes Survey), we analyzed Medicare Advantage patients diagnosed with cancer during 1998-2011, who completed surveys regarding HRQOL through 2013. 'Early Era' patients were treated during 1998-2003; 'Late Era' patients were treated during 2006-2011. After propensity score matching, post-diagnosis changes in health utility (HU), Physical Component Summary (PCS) and Mental Component Summary (MCS) scores were calculated and compared between the two eras., Result: We identified 208 older patients with prostate, 276 with breast and 76 with lung cancer who were treated in the 'Early Era' and matched to equal numbers in the 'Late Era'. Mean age of patients in early and late era was 72 and 73 years, respectively. The mean post-diagnosis decline in health utility for patients treated in the 'Late Era' was not significantly different from the 'Early Era' for any cancer (Prostate [early vs. late]: -0.06 vs. -0.03, p = .09; Breast: -0.03 vs. -0.04, p = .65; Lung: -0.07 vs. -0.07, p = .95); nor for Physical Component Summary or Mental Component Summary scores., Conclusion: Older patients treated for prostate, breast or lung cancer in the later era reported similar outcomes of changes in HRQOL compared to earlier era patients., Competing Interests: Declaration of Competing Interest This work was funded by the PhRMA Foundation Assessing the Benefits of Treating Cancer Research Starter Grant (JBY, LDC).

Purpose: As immune checkpoint inhibitors (ICIs) have transformed the care of patients with cancer, it is unclear whether treatment at the end of life (EOL) has changed. Because aggressive therapy at the EOL is associated with increased costs and patient distress, we explored the association between the Food and Drug Administration (FDA) approvals of ICIs and treatment patterns at the EOL., Methods: We conducted a retrospective, observational study using patient-level data from a nationwide electronic health record-derived database. Patients had advanced melanoma, non-small-cell lung cancer (NSCLC; cancer types with an ICI indication), or microsatellite stable (MSS) colon cancer (a cancer type without an ICI indication) and died between 2013 and 2017. We calculated annual proportions of decedents who received systemic cancer therapy in the final 30 days of life, using logistic regression to model the association between the post-ICI FDA approval time and use of systemic therapy at the EOL, adjusting for patient characteristics. We assessed the use of chemotherapy or targeted/biologic therapies at the EOL, before and after FDA approval of ICIs using Pearson chi-square test., Results: There was an increase in use of EOL systemic cancer therapy in the post-ICI approval period for both melanoma (33.9% to 43.2%; P < .001) and NSCLC (37.4% to 40.3%; P < .001), with no significant change in use of systemic therapy in MSS colon cancer. After FDA approval of ICIs, patients with NSCLC and melanoma had a decrease in the use of chemotherapy, with a concomitant increase in use of ICIs at the EOL., Conclusion: The adoption of ICIs was associated with a substantive increase in the use of systemic therapy at the EOL in melanoma and a smaller yet significant increase in NSCLC.

The ALLIANCE A041202 trial found that continuously administered ibrutinib in the first-line setting significantly prolonged progression-free survival compared with a fixed-duration treatment of rituximab and bendamustine in older adults with chronic lymphocytic leukemia (CLL). In this study, we created a Markov model to assess the cost-effectiveness of ibrutinib in the first-line setting, compared with a strategy of using ibrutinib in the third-line after failure of time-limited bendamustine and venetoclax-based regimens. We estimated transition probabilities from randomized trials using parametric survival modeling. Lifetime direct health care costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs) were calculated from a US payer perspective. First-line ibrutinib was associated with an improvement of 0.26 QALYs and 0.40 life-years compared with using ibrutinib in the third-line setting. However, using ibrutinib in the first-line led to significantly higher health care costs (incremental cost of $612 700), resulting in an ICER of $2 350 041 per QALY. The monthly cost of ibrutinib would need to be decreased by 72% for first-line ibrutinib therapy to be cost-effective at a willingness-to-pay threshold of $150 000 per QALY. In a scenario analysis where ibrutinib was used in the second-line in the delayed ibrutinib arm, first-line ibrutinib had an incremental cost of $478 823, an incremental effectiveness of 0.05 QALYs, and an ICER of $9 810 360 per QALY when compared with second-line use. These data suggest that first-line ibrutinib for unselected older adults with CLL is unlikely to be cost-effective under current pricing. Delaying ibrutinib for most patients with CLL until later lines of therapy may be a reasonable strategy to limit health care costs without compromising clinical outcomes., (© 2020 by The American Society of Hematology.)

Purpose: We aimed to determine whether insurance expansions implemented through the Affordable Care Act (ACA) were associated with changes in coverage status, disease stage, and treatment of younger adults with testicular germ cell tumors (GCT)., Materials and Methods: We identified men aged 18-64 diagnosed with testicular GCTs between 2010 and 2015 in the National Cancer Data Base. We defined time periods as: pre-ACA (2010-2013) and post-ACA (2014-2015) and used difference-in-differences (DID) modeling to examine associations between state Medicaid expansion status and changes in insurance, stage at diagnosis, and treatment., Results: Following the ACA, the proportion of patients with any health insurance increased 3.7% (95% CI 3-4.5) in Medicaid expansion states and 3.0% (95% CI 1.5-4.5) in non-expansion states, mainly by gaining Medicaid and private insurance, respectively. The largest increases occurred in low-income patients, where Medicaid expansion was associated with an adjusted increase of 14.5 percentage points (95% CI 7.2-21.8) in Medicaid coverage following the ACA. We did not observe reductions in late-stage diagnoses during the observation period. Changes in the proportion of patients receiving chemotherapy or radiation for advanced-stage cancers were ongoing prior to the ACA and differed between expansion and non-expansion states, limiting assessment of ACA-related effects on individual treatments., Conclusions: Post-ACA, the proportion of newly diagnosed testicular cancer patients with health insurance increased, with the largest effects seen among lowest income individuals. Our findings that changes in practice preceded the ACA and differed by expansion status highlight the need for caution in assessing the legislation's impact.

Background: Certain cancer types and subsequent treatment can cause or worsen pain and emotional distress, leading to functional limitation, particularly among a growing population of older adults with cancer., Methods: We constructed a national sample of older adult Medicare beneficiaries with cancer using the 2007-2012 Surveillance, Epidemiology and End Results (SEER)-Medicare Health Outcomes Survey (MHOS) database linked to Medicare Part D enrollment and prescription claims data. MHOS survey responses described functional limitations due to pain and emotional distress. Using multivariable logistic regression, we estimated the association between participant characteristics and patient-reported functional limitation due to pain and emotional distress and subsequent prescription medication use., Results: Among 9105 older adults with cancer, aged 66-102 years (y), 68.6% reported moderate to severe functional limitation due to pain, and 48.3% reported moderate to severe functional limitation due to emotional distress. Nearly 10% reported severe functional limitation due to co-occurring symptoms of pain and emotional distress. Significant predictors of severe functional limitation due to co-occurring symptoms included age ≥ 80y (ref: 66-69y, adjusted relative risk (aRR): 1.74; 95% confidence interval (CI) 1.39-2.18, p < .001), stage IV disease at diagnosis (ref: stage I, aRR: 2.08; CI 1.52-2.86, p < .001), and lung cancer (ref: breast cancer, aRR: 1.84; CI 1.30-2.61, p < .001). Among 892 participants reporting co-occurring symptoms, 32.5% received neither pain nor emotional distress prescription medication., Conclusions: Functional limitation due to pain and emotional distress persist among older adults with cancer, particularly octogenarians. Efforts to identify and target unmet supportive care needs to maintain functional independence are needed., Competing Interests: Declaration of Competing Interest Carolyn J.

Context: Concerns about the adequacy of pain management among older adults are increasing, particularly with restrictions on opioid prescribing., Objectives: To examine associations between prescription pain medication receipt and patient-reported pain interference in older adults with and without cancer., Methods: Using the 2007-2012 Surveillance Epidemiology and End Results (SEER)-Medicare Health Outcomes Survey (MHOS) database linked to Medicare Part D prescription claims, we selected MHOS respondents (N = 15,624) aged ≥ 66 years, ≤ 5 years of a cancer diagnosis (N = 9105), or without cancer (N = 6519). We measured receipt of opioids, non-steroidal anti-inflammatory drugs, and antiepileptics, and selected antidepressants within 30 days prior to survey. Patient-reported activity limitation due to pain (pain interference) within the past 30 days was summarized as severe, moderate, or mild/none. Logistic regression using predictive margins estimated associations between pain interference, cancer history, and pain medication receipt, adjusting for socio-demographics, chronic conditions, and Part D low-income subsidy., Results: Severe or moderate pain interference was reported by 21.3% and 46.1%, respectively. Pain medication was received by 21.5%, with 11.6% receiving opioids. Among adults reporting severe pain interference, opioid prescriptions were filled by 27.0% versus 23.8% (p = 0.040) with and without cancer, respectively. Over half (56%) of adults reporting severe pain in both groups failed to receive any prescription pain medication., Conclusions: Older adults with cancer were more likely to receive prescription pain medications compared with adults without cancer; however, many older adults reporting severe pain interference did not receive medications. Improved assessment and management of pain among older adults with and without cancer is urgently needed.

The hypomethylating agents (HMAs) azacitidine and decitabine have been the de facto standard of care for patients with acute myeloid leukemia (AML) who are unfit for intensive therapy. Using the Surveillance, Epidemiology, and End Results-Medicare linked database, we identified 2263 older adults (age ≥66 years) diagnosed with AML during 2005-2015 who received a first-line HMA; 1154 (51%) received azacitidine, and 1109 (49%) received decitabine. Median survival from diagnosis was 7.1 and 8.2 months (P < .01) for azacitidine- and decitabine-treated patients, respectively. Mortality risk was higher with azacitidine vs decitabine (hazard ratio [HR], 1.11; 95% confidence interval [CI], 1.01-1.21; P = .02). The findings were similar when evaluating only patients completing ≥4 cycles (42% of patients treated with either azacitidine or decitabine). These findings lost significance when evaluating those completing a standard 7-day schedule of azacitidine (34%) vs 5-day schedule for decitabine (66%) (HR, 0.95; 95% CI, 0.83-1.08; P = .43). Red blood cell (RBC) transfusion independence (TI) was achieved in one-third of patients with no difference between the 2 HMAs. In conclusion, the majority of older AML patients did not receive the minimum of 4 cycles of HMA often needed to elicit clinical benefit. We observed no clinically meaningful differences between azacitidine- and decitabine-treated patients in their achievement of RBC TI or survival., (© 2020 by The American Society of Hematology.)

Chromosome 1 abnormalities (C1As) are common genetic aberrations among patients with multiple myeloma (MM). We aimed to evaluate the significance of C1As among a contemporary cohort of patients with MM in the United States. We used electronic health records from the Flatiron Health database to select patients newly diagnosed with MM from January 2011 to March 2018 who were tested using fluorescence in situ hybridization within 90 days of diagnosis. We characterized patients as having documented C1As or other high-risk chromosomal abnormalities (HRCAs) as defined by the Revised-International Staging System (R-ISS) such as del(17p), t(14;16), and t(4;14). We used Kaplan-Meier methods to compare overall survival (OS) of patients with or without C1As and stratified log-rank tests (with the presence of HRCAs as a stratifying variable). We used Cox proportional hazards regression models to compare OS, adjusting for age, sex, stage, HRCAs, and type of first-line therapy. Of 3578 eligible patients, 844 (24%) had documented C1As. Compared with patients without C1As, patients with C1As were more likely to have higher stage (R-ISS stage III; 18% vs 12%), to have HRCAs (27% vs 14%), and to receive combinations of proteasome inhibitors and immunomodulatory agents (41% vs 34%). Median OS was lower for patients with C1As (46.6 vs 70.1 months; log-rank P < .001). C1As were independently associated with worse OS (adjusted hazard ratio, 1.42; 95% confidence interval, 1.19-2.69; P < .001), as were older age, higher R-ISS stage, HRCAs, and immunoglobulin A isotype. C1As were associated with inferior OS, independent of other HRCAs, despite greater use of novel therapies. Clinical trials testing newer therapies for high-risk MM should incorporate patients with C1As., (© 2020 by The American Society of Hematology.)

Hypomethylating agents (HMA) showed overall survival (OS) benefits in patients with higher-risk myelodysplastic syndromes (HR-MDS) in clinical trials. We conducted a retrospective cohort study of Surveillance, Epidemiology, and End Results (SEER)-Medicare data of patients ≥66 years diagnosed with refractory anemia with excess blasts (RAEB), a proxy for HR-MDS, in 01/2001-04/2004 (pre-period) or 01/2006-12/2011 (post-period). Association between post-period diagnosis and OS was examined using propensity scores (PS)-matched samples. Among 1876 RAEB patients, median OS was 9 months and 30.8% received HMAs (3.6% in pre-period; 43.0% in post-period) with no association between post-period diagnosis and OS. In the top PS quartile, post-period diagnosis was associated with a 74% lower risk of death (Hazard ratio [HR] = 0.26, 95%-CI: 0.10-0.69, p  = 0.007), while outcomes were worse in the lowest PS quartile (HR = 2.80, 95%-CI: 1.06-7.36, p  = 0.037). HMA lead to a 3-month OS benefit for patients most likely to receive HMA but not for unselected RAEB cohort.

Cytarabine-anthracycline based intensive induction chemotherapy (IC) remains the standard of care for remission induction among fit patients with newly diagnosed acute myeloid leukemia (AML) in the United States (US). However, the mortality rate outside of clinical IC trials, predictors of death, and resource utilization during admission for IC have not been thoroughly examined. We used the Premier Healthcare database to identify adult patients (aged 18-89 years) treated with cytarabine-anthracycline-based IC during their first recorded inpatient stay for AML during the contemporary period of 2010 to 2017. We identified factors associated with inpatient death or discharge to hospice, using multivariable logistic regression models. We also assessed the patterns of inpatient healthcare resource utilization. A total of 6442 patients with AML from 313 hospitals who were treated with IC were identified. Median age was 61 years (interquartile range [IQR], 50-68 years), and 56% were men. Median length of stay was 29 (IQR, 25-38) days, with rates of in-hospital death and discharge to hospice of 12.3% and 3.7% (17.9% and 6.3% among patients aged ≥65 years), respectively. Predictors of in-hospital death or discharge to hospice included older age, geographic region, and lower hospital volume. During admission, 28.0%, 12.6%, and 4.0% of patients required treatment in intensive care units, mechanical ventilation, and dialysis, respectively. Despite improvements in supportive care in the contemporary era, inpatient mortality during first hospitalization for adult patients with AML treated with IC in the US remains high particularly among older patients., (© 2020 by The American Society of Hematology.)

Context: Older adults with advanced lung cancer experience high symptom burden at end of life (EOL), yet hospice enrollment often happens late or not at all. Receipt of medications to manage symptoms in the outpatient setting, outside the Medicare hospice benefit, has not been described., Objectives: We examined patterns of symptom management medication receipt at EOL for older adults who died of lung cancer., Methods: This retrospective cohort used the Surveillance, Epidemiology, and End Results-Medicare database to identify decedents diagnosed with lung cancer at age 67 years and older between January 2008 and December 2013 who survived six months and greater after diagnosis. Using Medicare Part B and D claims, we identified monthly receipt of outpatient medications for symptomatic management of pain, emotional distress, fatigue, dyspnea, anorexia, and nausea/vomiting. Multivariable logistic regression estimated associations between medication receipt and patient demographic characteristics, comorbidity, and concurrent therapy., Results: Of the 16,246 included patients, large proportions received medications for dyspnea (70.7%), pain (62.5%), and emotional distress (49.4%), with lower prevalence for other symptoms. Medication receipt increased from six months to one month before death. Women and dual Medicaid enrolled were more likely to receive medications for pain, emotional distress, dyspnea, and nausea/vomiting. Receipt of symptom management medications decreased with increasing age and racial/ethnical minorities., Conclusion: Symptom management medication receipt was common and increasing toward EOL. Lower use by males, older adults, and nonwhites may reflect poor access or poor patient-provider communication. Further research is needed to understand these patterns and assess adequacy of symptom management in the outpatient setting., (Copyright © 2019 American Academy of Hospice and Palliative Medicine.

Population level survival of patients with myelodysplastic syndromes (MDS) treated with hypomethylating agents (HMA) is inferior to clinical trials. Using SEER-Medicare data, we identified 2086 MDS patients diagnosed in 2004-13, aged ≥66 years at diagnosis, and receiving ≥1 HMA cycle after 2005. We used multivariate logistic regression and Cox proportional hazards models to assess the impact of provider experience on persistent HMA therapy and overall survival (OS), respectively. Median number of HMA cycles was 4 and median OS was 10 months. Thirty-two percent of patients were treated by providers with ≥1 prior HMA initiation in the last 2 years and were more likely to receive ≥4 cycles of HMA therapy (OR = 1.29, 95% CI = 1.06-1.57; p  = .01). No significant association was found between MDS or HMA initiation volume and survival. In conclusion, while HMA initiation volume was associated with persistent HMA treatment, neither MDS nor HMA initiation volumes were associated with OS in older MDS patients.

Background: The majority of patients with acute myeloid leukemia (AML) are aged >65 years at the time of diagnosis and are not actively treated. The objective of the current study was to determine the prevalence, temporal trends, and factors associated with no active treatment (NAT) among older patients with AML in the United States., Methods: A retrospective analysis was performed of Surveillance, Epidemiology, and End Results (SEER)-Medicare data from 14,089 patients with AML residing in the United States who were diagnosed with AML at age ≥66 years during 2001 through 2013. NAT was defined as not receiving any chemotherapy, including hypomethylating agents. Multivariable logistic regression models were used to analyze sociodemographic, clinical, and provider characteristics associated with NAT., Results: The percentage of patients with NAT decreased over time from 59.7% among patients diagnosed in 2001 to 42.8% among those diagnosed in 2013. The median overall survival for the entire cohort was 82 days from the time of diagnosis. Patients treated with NAT had worse survival compared with those receiving active treatment. Variables found to be associated with higher odds of NAT included older age, certain sociodemographic characteristics (household income within the lowest quartile, residence outside the Northeast region of the United States, and being unmarried), and clinical factors (≥3 comorbidities, the presence of mental disorders, recent hospitalization, and disability)., Conclusions: Greater than one-half of older patients with AML residing in the United States do not receive any active leukemia-directed therapy despite the availability of lower intensity therapies such as hypomethylating agents. Lack of active therapy receipt is associated with inferior survival. Identifying predictors of NAT might improve the quality of care and survival in this patient population, especially as novel therapeutic options with lower toxicity are becoming available., (© 2019 American Cancer Society.)

Most patients with lower risk myelodysplastic syndromes (LR-MDS) become red blood cell (RBC) transfusion dependent at some time during their disease course. Hypomethylating agents (HMAs) are frequently used in this setting; however, reported rates of in RBC transfusion independence (TI) achieved with HMA therapy vary significantly between studies. Here we study the real-life clinical effectiveness of HMA in inducing RBC TI in anemic LR-MDS patients using the Surveillance, Epidemiology and End Results (SEER)-Medicare database. We find that approximately 40% of LR-MDS patients who were receiving RBC transfusions and 33% who were dependent on RBC transfusions at HMA initiation ultimately achieved TI. The receipt of ≥3 transfusions in the 8-week period before HMA initiation was significantly associated with lower odds of achieving TI. Our study provides important population level estimates of clinical effectiveness of HMAs in LR-MDS.

Background: With improving survival for patients with multiple myeloma (MM), supportive care that is focused on optimizing quality of life and minimizing treatment-related toxicities is increasingly important. The extent to which patients with MM are receiving recommended supportive care is unknown., Methods: This study used the Surveillance, Epidemiology, and End Results-Medicare database to identify older adults (age ≥66 years) diagnosed with MM in 2008-2013 who had received active treatment and survived 1 year or longer after their diagnosis. Outcomes of interest included guideline-recommended supportive care, which was defined as 1) bone-modifying drugs (BMDs) within the 12 months after the diagnosis, 2) influenza vaccination in the first season after the diagnosis, and 3) concomitant use of prophylactic antivirals with proteasome inhibitors. Multivariable logistic regression models were used to evaluate associations between patient/facility-level characteristics and supportive care use., Results: Among 1996 patients receiving MM-directed therapy, 64%, 52%, and 49% received BMDs, an influenza vaccination, and antiviral prophylaxis, respectively. Non-Hispanic black patients (odds ratio [OR] vs white patients, 0.63; 95% confidence interval [CI], 0.46-0.88) and patients with baseline renal impairment (OR, 0.43; 95% CI, 0.34-0.54) had lower odds of BMDs. Non-Hispanic blacks (OR, 0.52; 95% CI, 0.37-0.73) and those with dual Medicaid enrollment (OR, 0.76; 95% CI, 0.58-0.99) had lower odds of influenza vaccination. Treatment in a community-based setting was associated with reduced odds of antiviral prophylaxis (OR, 0.58; 95% CI, 0.46-0.72)., Conclusions: Substantial underutilization of guideline-recommended supportive care was observed among older adults with MM in the United States, and this was associated with both patient and facility characteristics.

Background: Provider experience, or clinical volume, is associated with improved outcomes in many complex healthcare settings. Despite increased complexity of anticancer therapies, studies evaluating physician-level experience and cancer treatment outcomes are lacking., Methods: A population-based study was conducted of older adults (aged ≥66 years) diagnosed with B-cell non-Hodgkin's lymphoma in 2004 through 2011 using SEER-Medicare data. Analysis focused on outcomes in patients receiving rituximab, the first approved monoclonal anticancer immunotherapy. We hypothesized that lower physician experience using rituximab and managing its infusion-related reactions would be associated with early treatment discontinuation. A 12-month look-back from each initiation of rituximab was used to categorize physician volume (0, 1-2, or ≥3 initiations per year). Modified Poisson regression was used to account for provider-level correlation and estimated relative risk (RR) of early rituximab discontinuation (<3 cycles within 180 days of rituximab initiation). Cox proportional hazards were used to measure the impact of rituximab discontinuation on survival., Results: Among 15,110 patients who initiated rituximab with 2,684 physicians, 7.6% experienced early rituximab discontinuation. Approximately one-fourth of patients (26.1%) initiated rituximab with a physician who had no rituximab initiations during the preceding 12 months. Compared with patients treated by physicians who had ≥3 rituximab initiations in the prior year, those treated by physicians without initiations were 57% more likely to experience early discontinuation (adjusted RR [aRR], 1.57; 95% CI, 1.35-1.82; P<.001 for 0 vs ≥3, and aRR, 1.19; 95% CI, 1.03-1.37; P=.02 for 1-2 vs ≥3). Additionally, rituximab discontinuation was associated with higher risk of death (adjusted hazard ratio, 1.39; 95% CI, 1.28-1.52; P<.001)., Conclusions: Lower oncologist experience with rituximab was associated with increased risk of early rituximab discontinuation in Medicare beneficiaries with non-Hodgkin's lymphoma. Physician-level volume may be an important factor in providing high-quality cancer care in the modern era.

Objectives: To evaluate the relationship between cancer history and cost-related medication nonadherence (CRN) as well as cost-coping strategies, by health insurance coverage., Methods: We used the 2013 to 2016 National Health Interview Survey to identify adults aged 18 to 64 years with (n = 3599) and without (n = 56 909) a cancer history. Cost-related changes in medication use included (1) CRN, measured as skipping, taking less, or delaying medication because of cost, and (2) cost-coping strategies, measured as requesting lower cost medication or using alternative therapies to save money. Separate multivariable logistic regressions were used to calculate the adjusted odds ratios (AORs) of CRN and cost-coping strategies associated with cancer history, stratified by insurance., Results: Cancer survivors were more likely than adults without a cancer history to report CRN (AOR 1.26; 95% confidence interval [CI] 1.10-1.43) and cost-coping strategies (AOR 1.10; 95% CI 0.99-1.19). Among the privately insured, the difference in CRN by cancer history was the greatest among those enrolled in high-deductible health plans (HDHPs) without health savings accounts (HSAs) (AOR 1.78; 95% CI 1.30-2.44). Among adults with HDHP and HSA, cancer survivors were less likely to report cost-coping strategies (AOR 0.62; 95% CI 0.42-0.90). Regardless of cancer history, CRN and cost-coping strategies were the highest for those uninsured, enrolled in HDHP without HSA, and without prescription drug coverage under their health plan (all P<.001)., Conclusions: Cancer survivors are prone to CRN and more likely to use cost-coping strategies. Expanding options for health insurance coverage, use of HSAs for those with HDHP, and enhanced prescription drug coverage may effectively address CRN., (Copyright © 2019 ISPOR–The Professional Society for Health Economics and Outcomes Research.

Background: The current study examined medical financial hardship in cancer survivors and those without a cancer history in the United States., Methods: The 2013 to 2016 National Health Interview Survey was used to identify cancer survivors (stratified by ages 18-49 years [1424 survivors], ages 50-64 years [2916 survivors], and ages ≥65 years [6014 survivors]) and individuals without a cancer history (ages 18-64 years [66,951 individuals], ages 50-64 years [31,741 individuals], and ages ≥65 years [25,744 individuals]). Medical financial hardship was categorized into 3 domains: 1) material (eg, problems paying medical bills); 2) psychological (eg, worrying about paying medical bills); and 3) behavioral (eg, delaying/forgoing care due to cost). Generalized ordinal logistic regressions were used to examine the associations between cancer history, hardship, and health insurance deductibles/health savings accounts (among privately insured cancer survivors aged 18-64 years only)., Results: Compared with those without a cancer history, cancer survivors were more likely to report any material (ages 18-49 years: 43.4% vs 30.1%; ages 50-64 years: 32.8% vs 27.8%; and ages ≥65 years: 17.3% vs 14.7%), psychological (ages 18-49 years: 53.5% vs 47.1%), and behavioral (ages 18-49 years: 30.6% vs 21.8%; and ages 50-64 years: 27.2% vs 23.4%) measure of financial hardship, and multiple domains of hardship (age groups 18-49 years and 50-64 years; all P < .01). Among privately insured survivors, having a high-deductible health plan without a health savings account was found to be associated with greater hardship compared with having low-deductible insurance., Conclusions: Younger cancer survivors are particularly vulnerable to material, psychological, and behavioral medical financial hardship. Interventions designed to reduce financial hardship should consider multiple domains of hardship as well as insurance benefit design., (© 2019 American Cancer Society.)

Physician ownership of imaging equipment has been shown to be associated with greater use of low-value imaging. However, it is unclear whether ownership also influences utilization of appropriate imaging. We conducted a cohort study of older adults diagnosed with three non-Hodgkin lymphomas with distinct guideline recommendations concerning the use of positron emission tomography (PET) during staging (recommended, not recommended, or equivocal). We found patients who were treated by oncologists with PET ownership were more likely to receive a staging PET regardless of lymphoma subtype. However, the difference in utilization by ownership status was smallest (6%, 95% confidence interval = 2% to 11%, P = .01) in the setting of diffuse large B cell lymphoma, where consensus guidelines recommend routine use of PET. Overall, removing financial incentives related to imaging self-referral may reduce utilization during cancer care, with the potential for greatest impact on imaging of equivocal or low clinical utility.

ABSTRACTBackground: Current guidelines recommend hydroxyurea (HU) as frontline therapy for patients with high-risk essential thrombocythemia (ET) to prevent thrombosis. However, little is known about the impact of HU on thrombosis or survival among these patients in the real-world setting., Patients and Methods: A retrospective cohort study was conducted of older adults (aged ≥66 years) diagnosed with ET from 2007 through 2013 using the linked SEER-Medicare database. Multivariable Cox proportional hazards regression models were used to assess the effect of HU on overall survival, and multivariable competing risk models were used to assess the effect of HU on the occurrence of thrombotic events., Results: Of 1,010 patients, 745 (73.8%) received HU. Treatment with HU was associated with a significantly lower risk of death (hazard ratio [HR], 0.52; 95% CI, 0.43-0.64; P<.01). Every 10% increase in HU proportion of days covered was associated with a 12% decreased risk of death (HR, 0.88; 95% CI, 0.86-0.91; P<.01). Compared with nonusers, HU users also had a significantly lower risk of thrombotic events (HR, 0.51; 95% CI, 0.41-0.64; P<.01)., Conclusions: Although underused in our study population, HU was associated with a reduced incidence of thrombotic events and improved overall survival in older patients with ET.
