Isolation and survival
Persistence of mortgage lending bias in the United States
Housing discrimination and racial segregation have a long history in the United States. The 1930's Home Owners' Loan Corporation (HOLC) "residential security maps," recently digitized, have become a popular visualization of Depression era mortgage lending risk patterns across American cities. Numerous housing policies have since been instituted, including the Home Mortgage Disclosure Act (HMDA), but mortgage lending bias persists. The degree to w…
Ecological Study of Variability in the Relationship between Liver Cancer Mortality and Racial Residential Segregation
Racial segregation has been identified as a predictor for the burden of cancer in several different metropolitan areas across the United States. This ecological study tested relationships between racial segregation and liver cancer mortality across several different metropolitan statistical areas in Wisconsin. Tract-level liver cancer mortality rates were calculated using cases from 2003-2012. Hotspot analysis was conducted and segregation scores…
Prevalence and Consequences of Axillary Lymph Node Dissection in the Era of Sentinel Lymph Node Biopsy for Breast Cancer
BACKGROUND: Despite clear guidelines for its use and wide adoption, no population-based study has examined the extent to which patients with early stage breast cancer are benefiting from sentinel lymph node biopsy (SLNB) by being spared a potentially avoidable axillary lymph node dissection (ALND) and its associated morbidity. OBJECTIVE: Examine variation in type of axillary surgery performed by surgeon volume; investigate the extent and conseque…
Socioeconomic Disparities in Mortality Among Women With Incident Breast Cancer Before and After Implementation of Medicare Part D
BACKGROUND: Breast cancer patients exhibit survival disparities based on socioeconomic status (SES). Disparities may be attributable to access to expensive oral endocrine agents. OBJECTIVES: Define recent socioeconomic disparities in breast cancer survival and determine whether these improved after implementation of the Medicare Part D program. DESIGN: Difference-in-difference natural experiment of women diagnosed and treated before or after impl…

Translating a Fall Prevention Intervention Into Practice
Objectives. We examined whether community translation of an effective evidence-based fall prevention program via standard monetary support can produce a community-wide reduction in fall injuries in older adults and evaluated whether an enhanced version with added technical support and capacity building amplified the fall reduction effect. Methods. We completed a randomized controlled community trial among adults aged 65 and older in (1) 10 contro…
Reexamining the Relationship of Breast Cancer Hospital and Surgical Volume to Mortality
OBJECTIVE: To reexamine the relationship of hospital and surgical volume to all-cause and breast cancer-specific mortality, taking into account the potential selection bias in patients treated at high-volume centers or by high-volume surgeons. DATA SOURCES: Elderly (65+) women with early-stage, incident breast cancer surgery in 2003. STUDY DESIGN: A population-based, prospective survey study. METHODS: Two-stage, instrumental variable regression m…
Does Neighborhood Environment Differentiate Intimate Partner Femicides From Other Femicides
We examined the association between neighborhood-level factors and intimate partner femicide (IPF) using Wisconsin Violent Death Reporting System (WVDRS) data and Wisconsin Coalition Against Domestic Violence (WCADV) reports, in concert with neighborhood-level information. After controlling for individual characteristics, neighborhood-level disadvantage was associated with a decreased likelihood of IPF status, as compared with other femicides, wh…
Characteristics of the Residential Neighborhood Environment Differentiate Intimate Partner Femicide in Urban Versus Rural Settings
PURPOSE: A growing body of work examines the association between neighborhood environment and intimate partner violence (IPV). As in the larger literature examining the influence of place context on health, rural settings are understudied and urban and rural residential environments are rarely compared. In addition, despite increased attention to the linkages between neighborhood environment and IPV, few studies have examined the influence of nei…
Relationship Between Number of Breast Cancer Operations Performed and 5-Year Survival After Treatment for Early-Stage Breast Cancer
Objectives. We examined the association between number of breast cancer operations performed in a hospital (hospital volume) and all-cause and breast cancer–specific mortality using a national database and statistical methods appropriate for clustering and reducing confounding. Methods. In a retrospective cohort study, we linked Surveillance, Epidemiology, and End Results tumor registry data with Medicare claims data. The cohort included 11225 Me…
Obesity and Risk for Death Due to Motor Vehicle Crashes
Objectives. We examined the role of body mass index (BMI) and other factors in driver deaths within 30 days after motor vehicle crashes. Methods. We collected data for 22 107 drivers aged 16 years and older who were involved in motor vehicle crashes from the Crashworthiness Data System of the National Automotive Sampling System (1997–2001). We used logistic regression and adjusted for confounding factors to analyze associations between BMI and dr…
