Systemic Hospital Effects Driving Racial Disparities in Non-Elective Cesarean Delivery: Evidence from the New York Metropolitan Area
The Effect of Childhood Health Status on Adult Health in China
Childhood health in China was poor in the 1950s and 1960s because of limited nutrition. In the last three decades, China has distinguished itself through its tremendous economic growth and improvements in health and nutrition. However, prior to such growth, access to good nutrition was more variable, with potentially important implications, not only for childhood health, but also for adult health, because of its long-term effects lasting into adu…
Changes in Smoking Behaviors following Exposure to Health Shocks in China
Background : Evidence suggests that following major individual health shocks, smokers change their smoking behaviors. However, little is known about the association between spousal health shocks and smoking. This study examined the contemporaneous and long-term effects of individual and spousal health shocks on males' smoking behaviors in China. Methods : This study employed a nation-wide data base from the 1991−2011 China Health and Nutrition St…
Does Migration Limit the Effect of Health Insurance on Hypertension Management in China
Background: In China, rapid urbanization has caused migration from rural to urban areas, and raised the prevalence of hypertension. However, public health insurance is not portable from one place to another, and migration may limit the effectiveness of this non-portable health insurance on healthcare. Our study aims to investigate whether migration limits the effectiveness of health insurance on hypertension management in China. Methods: Data wer…

Racial and ethnic disparities in amputation rates are substantial, with disease severity and hospital admission source being key factors
Urban-rural disparities in child nutrition-related health outcomes in China: The role of hukou policy
The hukou system exacerbates urban-rural disparities in child nutrition-related health outcomes independent of the well-known disparity stemming from urban-rural residence. Fortunately, however, child health disparities due to hukou have been declining since 2000

Physician-patient Language Concordance and Malpractice Concerns
OBJECTIVE: To study the association between physician-patient language concordance and physicians' malpractice concerns. METHOD: We use a nationally representative physician data set, the 2008 Health Tracking Physician Survey maintained by the Center for Studying Health System Change. The Health Tracking Physician Survey includes 5 assessments of physicians' concerns about malpractice risk. Physicians are also asked the percentage of patients the…
Variations in Healthcare Access and Utilization Among Mexican Immigrants: The Role of Documentation Status
The objective of this study is to identify differences in healthcare access and utilization among Mexican immigrants by documentation status. Cross-sectional survey data are analyzed to identify differences in healthcare access and utilization across Mexican immigrant categories. Multivariable logistic regression and the Blinder-Oaxaca decomposition are used to parse out differences into observed and unobserved components. Mexican immigrants ages…
Does smoking affect body weight and obesity in China
Explaining Urban-Rural Health Disparities in China
BACKGROUND: Given strict residency controls and geographic imbalances in health care resources, China may experience serious urban-rural health disparities. OBJECTIVES: To investigate urban-rural disparities in the patterns of health status and health care utilization in China and to examine the evolution of these disparities from 1997 to 2006. SUBJECTS: This study uses data from the China Health and Nutrition Survey 1997-2006 with a sample of 27…
Health Care Access, Use of Services, and Experiences Among Undocumented Mexicans and Other Latinos
BACKGROUND: We compared access to health care, use of services, and health care experiences for Mexicans and other Latinos by citizenship and immigrant authorization status. METHODS: We acquired data from the 2003 California Health Interview Survey, with 42,044 participants representative of noninstitutionalized households. Participants were differentiated by ethnicity/race, national origin, and citizenship/immigration authorization status. Outco…
Reference Incomes, Loss Aversion, and Physician Behavior
We examine the effects of reference income on the behavior of young male physicians. Using a unique panel of data, we relate physicians' reference and actual incomes to their subsequent income growth. Reference income has a strong positive effect on subsequent income for physicians who are below their reference points, but not for physicians who are at or above their reference points. Loss aversion, which posits a kink in utility at the reference…
Multicomponent Targeted Intervention to Prevent Delirium in Hospitalized Older Patients: What is the Economic Value
INTRODUCTION: Delirium, or acute confusional state, is a common and serious occurrence among hospitalized older persons. Current estimates suggest that delirium complicates hospital stays for more than 2.3 million older persons each year, involving more than 17.5 million hospital days and accounting for more than $4 billion (1994 dollars) of Medicare expenditures. A 40% reduction was recently reported in the risk for delirium among hospitalized o…
The Labor Productivity Effects of Chronic Backache in the United States
OBJECTIVES: Back pain afflicts approximately 31 million Americans, and is the number one cause of activity limitation in young adults. Little is known about the labor productivity costs associated with this chronic disease. Such information could provide useful input to employers considering alternative health benefits plans for managing their employees' health care needs. The goals of this study were to generate employee-level as well as nationa…
Health Care Utilization and Costs in a Medicare Population by Fall Status
OBJECTIVES: The economic impact of trauma in older persons is a matter of increasing concern to public health practitioners and planners, yet it is an issue that has not been widely studied. Available evidence does suggest, however, that falls are the costliest category of injury among older persons. METHODS: This study used data from the Health Care Financing Administration and the Connecticut Long-Term Care Registry to isolate the effects of fa…
The Cost-Effectiveness of a Multifactorial Targeted Prevention Program for Falls Among Community Elderly Persons
OBJECTIVES: Falls and fall injuries are common-potentially preventable-causes of morbidity, functional decline, and increased health-care use among elderly persons. The current analyses, performed on data obtained as part of a randomized controlled trial conducted within a health maintenance organization, describe the costs of a multifactorial, targeted prevention program for falls, present total net health-care costs, estimate the cost per fall …

Has Medicare Been a ‘Bad Deal’ for Rural Hospitals: A Multivariate Analysis of Financial Performance in Rural and Urban Hospitals During the First Four Years of the Prospective Payment System
Understanding the links between Medicare involvement and financial performance in rural hospitals is important for evaluating reimbursement policy under Medicare's prospective payment system (PPS). While simple comparisons between urban and rural hospitals suggest that the latter have lower PPS profit margins on average, there is little multivariate evidence on how Medicare involvement affects financial performance in rural hospitals and whether …
Physician Referrals and the Medical Market Place
Factors determining the extent to which physicians obtain new patients through referrals are examined. A more thorough understanding of physician referral patterns can help to explain how competitive forces function in this market and how physician characteristics and credentials affect individual performance. Referral networks promote entry by young physicians into both primary and nonprimary care medical markets. Nevertheless, there are marked …
Who Cares for Uninsured Persons: A Study of Physicians and Their Patients Who Lack Health Insurance
Physician involvement with uninsured patients is a topic of increasing policy interest. In the past, data limitations have hindered analysis of factors influencing physician contact with uninsured patients. This article attempts to bridge this gap in the health services research literature. Using a nationally representative sample of nonfederal patient care physicians, the study revealed marked variations in physician involvement with uninsured p…
Advertising and Entry: The Case of Physician Services
This paper examines the entry implications of physician advertising. Evidence suggests that advertising inhibited entry into this market. Nevertheless, experienced physicians (incumbents), to whom advertising would offer the greatest financial benefit, in fact advertise less--a paradox that may be explained by nonfinancial concerns, such as unwillingness to break well-internalized professional norms against advertising. Physician advertising has …
Physician Contact With and Attitudes Toward HIV-Seropositive Patients: Results From a National Survey
The growing population of HIV-seropositives raises serious concerns about who will provide medical care to this group. This article presents the first national estimates of physician involvement in, and attitudes toward, the treatment of HIV-seropositive patients. Nearly 50% of the nonfederal patient care physicians in our nationally representative sample have treated at least one HIV patient, with an average of 6.7 such patients being treated pe…

Physician Advertising Revisited
This article examines the determinants of physician advertising using a nationally representative sample of 2,573 self-employed physicians. In contrast to a previous study by Folland, this article identifies a number of physician characteristics that are strongly related to the advertising decision. In particular, female physicians and foreign medical graduates (FMGs) are significantly less likely to advertise than are males and non-FMGs, respect…
