Cross-border utilization of health care: evidence from a population-based study in south Texas

Objective. To assess the prevalence of health care utilization in Mexico by Texas border residents and to identify the main contributing factors to their cross‐border utilization of health care services. Data and Methods. This study used primary data from a population‐based telephone survey that was conducted in the whole Texas border area in 2008. The survey included responses from 1,405 adults. Multivariate logistic regression models were estimated to determine predictors of utilizing a wide range of health care services in Mexico. Principal Findings. Forty‐nine percent of the sample reported having ever purchased medications in Mexico, followed by 41 percent for dentist visits, 37.3 percent for doctor visits, and 6.7 percent for inpatient care. The most significant predictors of health care utilization in Mexico were lack of U.S. health insurance coverage, dissatisfaction with the quality of U.S. health care, and poor self‐rated health status. Conclusions. The high prevalence of use of health care services in Mexico by Texas border residents is suggestive of unmet needs in health care on the U.S. side of the border. Addressing these unmet needs calls for a binational approach to improve the affordability, accessibility, and quality of health care in the U.S.–Mexico border region.     

Measuring Tijuana residents' choice of Mexican or U.S. health care services

There is growing concern that the indigent health care burden in the southwestern United States may be caused partly by Mexican residents who cross the border to use U.S. health services. This article describes the first attempt to measure the extent of this use by border residents. It also compares factors associated with their use of health care services in both the United States and Mexico. Data were obtained from a household survey conducted in Tijuana, Mexico, near the California border, using a random, stratified analytic sample of 660 households that included a total of 2,954 persons. The dependent variables--extent and volume of contacts with health professionals--were examined according to sociodemographic characteristics, insurance coverage, payment modality, type of visit, and health care setting. The results indicate that 40.3 percent of the Tijuana population used health services exclusively in Mexico during a 6-month period, compared with only 2.5 percent who used services in the United States. Of the Mexican users of U.S. services, the largest proportion appeared to be older people, lawful permanent residents or citizens of the United States who are living in Mexico, and persons from high- or middle-income sectors. In addition to the low level of use of U.S. health services, the findings show that more than 84 percent of the visits were to providers in the private sector and, for 59 percent of the visits, a fee for services was implied. Overall, this border population does not seem to be a drain on the U.S. public health system.(ABSTRACT TRUNCATED AT 250 WORDS)     

Acculturation and Cross-Border Utilization of Health Services

Health services from Mexico constitute an important source of care for U.S. residents living along the U.S.-Mexico border. Data from The Cross-Border Utilization of Health Care Survey (n = 966) were used to estimate logit models that related acculturation, as measured by generational status, to the use of medication, physician, dental, and inpatient services from Mexico by U.S. residents in the Texas border region. Relative to first-generation Mexican immigrants, later-generation Mexican-Americans were progressively less likely to go to Mexico for health services. This finding holds with or without adjusting for the effects of selected demographic and socioeconomic variables. Addressing unmet needs in medical care in the southwestern U.S. border area should go beyond a simple expansion of health insurance coverage--it is also important to deliver health services that are sensitive to generational differences within the population in terms of linguistic and cultural barriers to health care access.     

Uninsurance,Underinsurance, and Health Care Utilization in Mexico by US Border Residents

Using data from the 2008 Cross-Border Utilization of Health Care Survey, we examined the relationship between United States (US) health insurance coverage plans and the use of health care services in Mexico by US residents of the US-Mexico border region. We found immigrants were far more likely to be uninsured than their native-born counterparts (63 vs. 27.8 %). Adults without health insurance coverage were more likely to purchase medications or visit physicians in Mexico compared to insured adults. However, adults with Medicaid coverage were more likely to visit dentists in Mexico compared to uninsured adults. Improving health care access for US residents in the southwestern border region of the country will require initiatives that target not only providing coverage to the large uninsured population but also improving access to health care services for the large underinsured population.     

Utilization of physician health care services in Mexico by U.S. Hispanic border residents

One of the most controversial topics in the U.S. is the issue of accessibility to health services by U.S. residents. This issue is most critical to U.S. Hispanic residents living along the U.S.-Mexico border who have been identified as having low health standards and low socio-economic conditions when compared to the rest of the state and the country. The availability of lower cost health services across the U.S. border in Mexico is, therefore, perceived as a viable economic alternative source of health care. This study is derived from a health needs assessment survey of 1,100 households residing in Laredo, Texas, the largest land port along the 2,000-miles long U.S.-Mexico border. The major result of this study indicates that about 41.2 percent of the Laredo U.S. Hispanic residents are utilizing cross border physician health care services in Mexico.     

Determinants of influenza vaccination in hard-to-reach urban populations

OBJECTIVE: Influenza vaccination rates among disadvantaged minority and hard-to-reach populations are lower than in other groups. We assessed the barriers to influenza vaccination in disadvantaged urban areas. METHODS: We conducted a cross-sectional study, using venue-based sampling, collecting data on residents of eight neighborhoods throughout East Harlem and the Bronx, New York City. RESULTS: Of 760 total respondents, 461 (61.6%) had received influenza vaccination at some point in their life. In multivariable models, having access to routine medical care, receipt of health or social services, having tested positive for HIV, and current interest in receiving influenza vaccination were significantly associated with having received influenza vaccination in the previous year. Of participants surveyed, 79.6% were interested in receiving an influenza vaccination at the time of survey. Among participants who had never previously received influenza vaccination in the past, 73.4% were interested in being vaccinated; factors significantly associated with an interest in being vaccinated were minority race, lower annual income, history of being homeless, being uninsured/underinsured, and not having access to routine medical care. CONCLUSIONS: Participants who are unconnected to health or social services or government health insurance are less likely to have been vaccinated in the past although these persons are willing to receive vaccine if it were available.     

Equity of access to health care for older adults in four major Latin American cities.

OBJECTIVES: To identify if older adults have equitable access to health services in four major Latin American cities and to determine if the inequities that are found follow the patterns of economic inequality in each of the four nations studied. METHODS: Data from persons age 60 and over in the cities of S?o Paulo, Brazil (n = 2,143); Santiago, Chile (n = 1,301); Mexico City, Mexico (n = 1,247); and Montevideo, Uruguay (n = 1,450) were collected through a collaboration led by the Pan American Health Organization. For our study, three process indicators of access (availability, accessibility, and acceptability) and one indicator of actual health services use (visit to a medical doctor in the past 12 months) were analyzed by wealth quintiles, health insurance type, education, health status, and demographic characteristics. RESULTS: Each of the four cities had a different level of access to care, and those levels of access were only weakly related to per capita national wealth. Given the relatively high level of wealth inequality in Brazil and the lower level in Uruguay, older persons in S?o Paulo had better-than-expected equity in access to care, while older persons in Montevideo had less equity than expected. Inequity in Mexico City was driven primarily by low levels of health insurance coverage. In Santiago, inequity followed socioeconomic status more than it did health insurance. CONCLUSIONS: In the four cities studied, health insurance and the operation of health systems mediate the link between economic inequality and inequitable access to health care. Therefore, special attention needs to be paid to equity of access in health services, independent of differences in economic inequality and national wealth.     

Giving birth across the border: the San Diego-Tijuana connection.

Large immigration flows of young Mexican women to the U.S.-Mexico border are increasing the demand for maternity services in the Southwest. To date no attempt has been made to determine how U.S. births are distributed among stable, permanent residents and transient migrants, such as border residents of Mexico who enter the U.S. temporarily, yet long enough to use health services. This exploratory study examines factors associated with childbirth in California by border residents of Tijuana, Mexico. Data on 184 women, 15-44 years old, who gave birth between 1982-87, were examined using a household survey and focus group discussions. The findings indicate that 10.4% of the sample crossed the border to give birth in the United States. Socio-economic and legal status, spoken English proficiency, history of U.S. residency, annual visits across the border, single parenthood and primiparity were factors significantly associated with childbirth in the United States. These factors, in addition to social class differentials in attitudes towards U.S. obstetrical care and citizenship-by-birth need to be examined in future studies of cross-border utilization of services. The findings also demonstrate that most U.S. deliveries were in the private sector and paid for out of pocket, representing a very low public health burden. Changes in Medicaid legislation, which have extended maternity care coverage to the undocumented, may encourage deliveries in the public sector. These effects, coupled with the bridging effects that newly legalized immigrant networks exert on friends and relatives, familiarizing them with U.S. health care resources, will require monitoring to determine changes in demand for U.S. maternity care by this population.     

The cost of rationing medical care by insurance coverage and by waiting

This paper raises the question of the least-cost institutional mechanism to secure the value of certainty by reducing risk over the purchase of medical care. Two methods of reducing risk are evaluated: financing medical care with ‘complete insurance’, that is, ready access to medical care that is free at the point of purchase; and rationing by waiting time in a national health service that supplies a limited volume of medical care. The first system corresponds to the type of insurance held by most people in the United States, while the latter represents a stylized model of a national health service. The cost of over-utilization of services by insured consumers in the U.S. is substantial - larger on a per-family basis, and far larger for the nation, than the cost of under-utilization by those who lack insurance. The cost of rationing by waiting is estimated to be between $541 and $828 per family (in 1984 dollars). Thus, both systems involve costly mis-allocation of resources.     

Differences in access to health care services among adults in rural America by rural classification categories and age

Objective: To study differences in excess to health care services between different population groups in rural areas of the United States. Design: Using data from the 1994 National Health Interview Survey and the 1991 Area Resource File, we examined the differences in excess with seven measures: having a regular source of care, having a usual place of care, having health insurance coverage, delaying medical care because of cost for all rural residents; number of doctor visits, number of hospital discharges and length of hospital stay per discharge for those who reported their health as being either poor or fair. Rural residents were classified by ages and grouped into four rural classification categories that were characterised along two dimensions: adjacent to a metropolitan statistical area (MSA) (yes/no) and inclusion of a city of at least 10 000 people (yes/no). Setting: Rural areas Subjects: Rural populations. Results: Residents aged 18–24 years had the worst access to services and the residents aged 65 years and over had the best access to services when measured by regular source of care, a usual place of care and health insurance status. Compared to those aged 50–64 years, residents aged 25–49 years were less likely to report having health insurance and more likely to report delaying seeking medical care because of costs. Rural residents who lived in a county adjacent to an MSA generally were less limited in access than those who lived in a county not adjacent to an MSA. Conclusions: Rural America is not a homogeneous entity in many aspects of the access to health care services.     

Self-perceived unmet health care needs of persons enrolled in hiv care

We examined the prevalence of, and factors associated with unmet health service needs among persons with HIV disease. Data were examined from 1,851 participants in the U.S. AIDS Cost and Service Utilization Study, drawn from 26 medical care providers in 10 cities. Geographic areas with large numbers of AIDS cases, and health care providers within them were chosen as study sites. After completing a screener questionnaire, potential participants at each site were stratifed by illness stage, HIV exposure route, and insurance status; a systematic random sample within those strata were selected for the study. Participants completed a comprehensive survey of HIV-related service use and costs, which also asked them to identify unmet health service needs. Analyses identified the relationship between unmet needs and: stage of illness, type of insurance, source of care, living arrangement, and AIDS prevalence of respondents' geographic region. At least one unmet need was reported by 20% of the sample. Needs for non-institutional services, e.g., dental care, mental health, and medications were more likely to be unmet than need for emergency room and hospital care. While most factors significantly affected the odds of having an unmet need, the greatest effects were found for private insurance and HIV asymptomatic status, both of which decreased the odds of unmet needs by approximately 50%. These findings suggest that insurance coverage for services required during the chronic phase of HIV illness is inadequate and should be augmented.This study was conducted under a subcontract with Westat Inc.     

Crossing the border for health care

A survey was administered to adults attending a health fair in south Los Angeles County, approximately 140 miles from the U.S.-Mexico border. The survey revealed that 14 percent of respondents had crossed the border to seek medical care during the past year. Nearly 80 percent of respondents crossing the border for medical care were uninsured, while 70 percent reported the low cost of medical care obtained across the border as being the most common reason for seeking care there. Twenty-eight percent of respondents reported purchasing medication in Mexico, with antibiotics and pain medication being reported in highest frequency. Ninety percent of these respondents were uninsured. This study shows that the high cost of health care and lack of insurance compels the poor and uninsured to seek low-cost health care and medication in Mexico to meet their most urgent health care needs, despite the burden of cost and travel.     

Health care access in three nations: Canada, insured America, and uninsured America.

This analysis provides new statistics for one of the oldest and fiercest debates in American health policy: whose residents have better access to health care, the United States' or Canada's? Data from the 2002-2003 Joint Canada U.S. Survey of Health show that, despite major differences in their health systems, most Canadians and Americans get the care they need. However, one group of Americans is much more likely to report serious access barriers--the uninsured. About one-third of currently or recently uninsured Americans, aged 18 to 64, said they could not get needed health care (over three times the rate of insured Americans or Canadians). Compared with Canadians and insured Americans, the uninsured are less likely to use hospital or physician services, and those who do are less satisfied with the care they receive. They are also less likely to purchase prescribed medications, due to cost. From a consumer perspective, the most salient feature of the Canadian system is its universality. In contrast, insured Americans under age 65 are at risk of losing their insurance and facing substantial access barriers.     

A community survey of medical errors in New York.

OBJECTIVE: To assess factors related to experiences with medical errors by health care consumers in the community. DESIGN: Using a random telephone survey of New York State residents screened for knowledge of health care utilization, we gathered information about demographic factors, health care attitudes, experiences with the health care system, and use of information to make health care decisions. SETTING: The State of New York, USA. PARTICIPANTS: Adults living in the State of New York who possessed a telephone. INTERVENTIONS: None. RESULTS: Approximately one-fifth (21.1%) of New Yorkers reported that either they or someone in their household had experienced a medical error, with logistic regression models for ever experiencing a household medical error revealed that respondents who were divorced/separated/widowed, African American, and those from higher income households were less likely to report medical errors. Conversely, those between the ages of 30 and 65 years, those who had frequent doctor visits, and those who were better informed about health care were more likely to report them. The results were similar for household medical errors in the past 5 years. In all multivariate models, greater use of medical information was consistently related to experiencing household medical errors. Having a regular doctor, having health insurance, and concern about health care delivery were not related to either of these outcomes. CONCLUSIONS: Our study indicated that one-fifth of New York State households had experienced a medical error, with one in 10 reporting experiencing a household medical error within the past 5 years. Greater knowledge about health care increased the likelihood of reporting a household medical error. Thus, a greater consumer orientation in health care and provision of more medical information may increase rather than reduce the reporting of medical errors by the public.     

Mexican Women Seeking Safe Abortion Services in San Diego,California

Except for in Mexico City, abortion is legally restricted throughout Mexico, and unsafe abortion is prevalent. We surveyed 1,516 women seeking abortions in San Diego, California. Of these, 87 women (5.7%) self-identified as Mexican residents. We performed in-depth interviews with 17 of these women about their experiences seeking abortions in California. The Mexican women interviewed were generally well-educated and lived near the U.S.–Mexican border; most sought care in the United States due to mistrust of services in Mexico, and the desire to access mifepristone, a drug registered in the United States for early medical abortion. Several reported difficulties obtaining health care in Mexico or reentering the United States when they had postabortion complications. Several areas for improvement were identified, including outreach to clinics in Mexico.     

Access to and use of ambulatory health care by a vulnerable Mexican American population on the U.S.-Mexico border.

The objective of this study was to determine if health care access is equitable and effective for Mexican Americans at the U.S.-Mexico border. The design was a cross-sectional telephone and door-to-door survey using the Behavioral Risk Factor Surveillance System, and the subjects were 1,409 El Paso County residents, ages 18 to 64 years. After controlling for other predisposing, enabling, and need characteristics, the presence of health insurance was significantly associated with health care use in the past year, both for a checkup (odds ratio [OR] = 2.48; 95 percent confidence interval [CI] = 1.83, 3.38) and a visit for any reason (OR = 2.20; 95 percent CI = 1.60, 3.04). Findings were similar for a regular source of care. Those who reported a checkup in the past year were significantly more likely to receive clinical preventive services. The lack of health insurance and a regular source of care for Mexican Americans on the U.S.-Mexico border creates significant inequalities in access to care.     

Access to health care: differences between insured and uninsured patients in south Minneapolis

This article reports the results of a survey of 575 patients who were seen at 2 clinics in south Minneapolis. About half had health insurance. We found a strong connection between not having insurance and going without medical care. We also found that when the uninsured do go for care, they often fail to take prescribed medications because of the cost. Our findings also contradicted some prevalent thinking about the uninsured: that they are unemployed, that they refuse employer-sponsored insurance, and that they can easily get care at free clinics.     

Utilization of home care among people with HIV infection.

OBJECTIVE: To examine factors affecting the utilization of formal and informal home care services by people with HIV infection. DATA SOURCES AND STUDY SETTING: Study participants are adults with HIV infection receiving services at major providers of medical care in ten U.S. cities. Six interviews were conducted over an 18-month period (March 1991 to September 1992). DATA COLLECTION METHODS: Data on home care utilization, personal background characteristics, insurance status, and functional status are based on self-report. Disease stage is based on medical record data. STUDY DESIGN: This is an observational study using a panel survey design. Cross-tabular and longitudinal regression analyses (N = 1,727) were conducted to determine the effects of sociodemographic factors, functional status, disease stage, and insurance status on the receipt of home care from nurses, paraprofessionals, other professional providers, household residents, nonresident family and friends, and volunteers. PRINCIPAL FINDINGS: Over a 12-month period, 16 percent of respondents received home nursing visits; 11 percent received paraprofessional care (e.g., nurse's aides, helpers); 4 percent received help from volunteers; 11 percent from non-resident family or friends, and 21 percent from household members. Among the subgroup with AIDS (n = 837), corresponding percentages were 29, 20, 7, 17, and 29 percent for each provider type. In multivariate analyses, illness stage and functional status had strong effects on odds of utilization. Blacks and Hispanics were less likely than whites to have nursing care, but racial/ethnic group did not affect receipt of informal care. CONCLUSIONS: Home care utilization is concentrated among people with AIDS, compared to those at less advanced disease stages. In addition to functional limitations, fatigue is associated with the use of home care. Nursing and non-nursing home care have somewhat different correlates. Medicaid may provide better coverage of personal care services than private insurance.     

HIV Positive Hispanic/Latinos Who Delay HIV Care: Analysis of Multilevel Care Engagement Barriers

This article overviews a Health Resources and Services Administration (HRSA) study with a sample population consisting of 470 Hispanic/Latino persons living with HIV/AIDS who received primary HIV/AIDS medical services from one of five HRSA Special Projects of National Significance (SPNS) Border Health demonstration projects. The study purpose was to identify multilevel barriers that affect delayed entry into HIV/AIDS medical care among Hispanic/Latino persons living along the U.S.–Mexico border. Multilevel variables along individual, community/cultural, and structural/systems were assessed relative to delayed care entry. The results of this examination indicate that individual and structural/system-level variables affect delayed care entry, whereas support was not found for community/cultural-level barriers. Study findings inform treatment engagement strategies aimed to decrease HIV disease progression by bringing Hispanic/Latinos into care sooner.
