High-Cost Cancer Drug Use in Medicare Advantage and Traditional Medicare
In this cohort study, high-cost drugs were more commonly prescribed among patients enrolled in TM and diagnosed with CRC. A similar pattern was not observed for patients with NSCLC, perhaps because clinical evidence suggests survival benefits to be associated only with certain drugs, all of which are expensive. Nonetheless, MA was modestly associated with reduced high-cost drug utilization and may reduce overall treatment costs
WeCanWork study
Our study highlights worker well-being differences approximately three months after initiating cancer treatment between men with and without physically demanding jobs. There are opportunities for employers to support worker well-being, specifically those with physically demanding jobs. Additionally, male cancer survivors with physically demanding jobs may need greater support outside of the workplace. Future research with a larger and longitudina…
The Effect of Medicare Annual Wellness Visits on Breast Cancer Screening and Diagnosis
OBJECTIVE: The Medicare Annual Wellness Visit (AWV)-a prevention-focused annual check-up-has been available to beneficiaries with Part B coverage since 2011. The objective of this study was to estimate the effect of Medicare AWVs on breast cancer screening and diagnosis. DATA SOURCES AND STUDY SETTING: The National Cancer Institute's Surveillance, Epidemiology, and End Results cancer registry data linked to Medicare claims (SEER-Medicare), HRSA's…
Building Data Infrastructure for Disease-Focused Health Economics Research
BACKGROUND: Data infrastructure for cancer research is centered on registries that are often augmented with payer or hospital discharge databases, but these linkages are limited. A recent alternative in some states is to augment registry data with All-Payer Claims Databases (APCDs). These linkages capture patient-centered economic outcomes, including those driven by insurance and influence health equity, and can serve as a prototype for health ec…
Capitalizing on Central Registries for Expanded Cancer Surveillance and Research
BACKGROUND: State central cancer registries are an essential component of cancer surveillance and research that can be enriched through linkages to other databases. This study identified and described state central registry linkages to external data sources and assessed the potential for a more comprehensive data infrastructure with registries at its core. METHODS: We identified peer-reviewed papers describing linkages to state central cancer reg…
The Impact of Massachusetts Health Reform on Colorectal and Breast Cancer Stage at Diagnosis
BACKGROUND: This study examines the expansion of health insurance coverage in Massachusetts under state health reform as a natural experiment to investigate whether expanded insurance coverage reduced the likelihood of advanced stage colorectal cancer (CRC) and breast cancer (BCA) diagnosis. METHODS: Our study populations include CRC or BCA patients aged 50-64 years observed in the Massachusetts Cancer Registry and Surveillance Epidemiology and E…
Impact of cash incentives for low-income individuals to seek a primary care visit on mental health outcomes
Value of Public Health Funding in Preventing Hospital Bloodstream Infections in the United States
Objectives. To estimate the association of 1 activity of the Prevention and Public Health Fund with hospital bloodstream infections and calculate the return on investment (ROI). Methods. The activity was funded for 1 year (2013). A difference-in-differences specification evaluated hospital standardized infection ratios (SIRs) before funding allocation (years 2011 and 2012) and after funding allocation (years 2013 and 2014) in the 15 US states tha…

Trends in the Treatment of Metastatic Colon and Rectal Cancer in Elderly Patients
BACKGROUND: Little is known about the use and costs of antineoplastic regimens for elderly patients with metastatic colorectal cancer (mCRC). We report population-based trends over a 10-year period in the treatment, survival, and costs in mCRC patients, stratified by ages 65-74 and 75+. METHODS: We used Surveillance, Epidemiology, and End Results-Medicare data for persons diagnosed with metastatic colon (N=16117) or rectal cancer (N=4008) between…
Work Continuation while Treated for Breast Cancer
Given the short- and long-term disabilities associated with breast cancer and its treatment, the authors investigate the influence of workplace accommodations on the employment and hours worked of women newly diagnosed with breast cancer. Accommodations that allow women to work fewer hours or that ease the burden of work could also generate health benefits by reducing workplace demands and allowing women more time to tend to treatment needs and r…
Prostate Cancer Treatment and Survival
BACKGROUND: The absence of evidence-based guidelines for prostate cancer treatment led the Institute of Medicine to include localized prostate cancer treatment among the 25 most important topics for comparative effectiveness research. OBJECTIVE: This study compared prostate cancer treatment and survival in men with and without prevalent comorbid conditions. RESEARCH DESIGN: The sample comprised elderly men, aged 66 years and older, extracted from…
Contraceptive Insurance Mandates and Consistent Contraceptive Use Among Privately Insured Women
INTRODUCTION: Half of the states in the United States mandate that health insurers cover contraceptives. Health care reform includes recommendations to extend these mandates nationally through the essential benefits package. This study evaluates the association of state-level insurance mandates and consistent contraceptive use among privately insured women aged 15-44. STUDY DESIGN: The National Survey of Family Growth (2006-2008) included 2276 pr…
Incremental Value of Using Medicaid Claim Files to Study Comorbid Conditions and Treatments in Dually Eligible Beneficiaries
BACKGROUND: Although investigations using Medicare claims files are ubiquitous in the health services research literature, Medicaid claims files are used less frequently. Nonetheless, Medicaid is the major payer for healthcare among low-income persons. OBJECTIVE: To assess the added value of Medicaid claim files for identifying comorbid conditions and cancer treatments in a dually eligible sample. RESEARCH DESIGN: Data were obtained from linked s…
Inadequate Access to Surgeons
OBJECTIVE: To compare the likelihood of seeing a surgeon between elderly dually eligible non-small-cell lung cancer (NSCLC) and colon cancer patients and their Medicare counterparts. Surgery rates between dually eligible and Medicare patients who were evaluated by a surgeon were also assessed. METHODS: We used statewide Medicaid and Medicare data merged with the Michigan Tumor Registry to extract a sample of patients with a first primary NSCLC (n…
Differences in Breast Cancer Diagnosis and Treatment
To explore how well the safety net performs at eliminating differences in diagnosis and treatment of insured and uninsured women with breast cancer, we compared insured and uninsured women treated in a safety-net setting. Controlling for socioeconomic characteristics, uninsured women are more likely to be diagnosed with advanced disease, requiring more extensive treatment relative to insured women, and also experience delays in initiating and com…
Influence of Patient-Provider Communication on Colorectal Cancer Screening
BACKGROUND: Screening reduces incidence and mortality from colorectal cancer (CRC). Despite improved access, screening is suboptimal and disparate among minority groups. Quality of patient-provider communication may impact CRC screening. OBJECTIVES: We examined the relationship between patient-provider communication and socioeconomic variables on the receipt of CRC screening using data from the Medical Expenditure Panel Survey. SUBJECTS: All pers…
Diagnosis of Advanced Cancer Among Elderly Medicare and Medicaid Patients
BACKGROUND: Medicaid is implicated in late-stage cancer diagnoses, which is the primary indicator of a poor prognosis. OBJECTIVE: We examined Medicaid enrollment and cancer diagnosis in patients ages 66 years and older. Medicaid enrollment was defined as enrolled 12+ months before diagnosis, enrolled <12 months before diagnosis, and enrolled after diagnosis. SUBJECTS: Medicaid and Medicare administrative data were merged with the Michigan Tumor R…
Health Care Disparities and Cervical Cancer
Objectives. We compared cervical cancer incidence, stage at diagnosis, and survival in Medicaid-insured and non–Medicaid-insured populations. Methods. We stratified the sample by age and used ordered logistic regression to predict stage at diagnosis and used Cox proportional hazards regression to predict survival. Results. Medicaid insured nearly one quarter of women diagnosed with cervical cancer. The likelihood of late-stage disease was greates…
Late Stage Cancers in a Medicaid-insured Population
BACKGROUND: Medicaid insurance promotes screening for early stage cancers. However, previous research suggests that Medicaid recipients are at risk for late stage disease. OBJECTIVE: To identify differences in stage of diagnosis between cancer patients enrolled in Medicaid before versus after their disease was identified, as well as differences in diagnostic stage between Medicaid enrollees and other patients. DESIGN: Analyses of a linked databas…
