Epidemiological changes and financial consequences of hypertension in Latin America: implications for the health system and patients in Mexico

The aim of this study was to assess the costs and financial consequences of epidemiological changes in hypertension in Mexico. The cost evaluation method to estimate costs was based on instrumentation techniques. To estimate the epidemiological changes and expected cases of hypertension in 2010-2012, three probabilistic models were constructed according to the Box-Jenkins technique. Comparing the economic impact, from 2010 to 2012 there will be a 24% increase in financial requirements (p < 0.05). The total cost of hypertension in 2011 will be US$ 5,733,350,291, including US$ 2,718,280,941 in direct costs and US$ 3,015,069,350 in indirect costs. If the risk factors and various healthcare models remain unaltered in the institutions analyzed here, the financial consequences will have a major impact on users' pockets, followed by social security providers and public healthcare providers. The authors suggest a revision in the planning, organization, and allocation of resources, particularly programs for health promotion and prevention of hypertension.     

Epidemiological and financial indicators of hypertension in older adults in Mexico: challenges for health planning and management in Latin America

This study estimated the epidemiological and financial indicators of hypertension in order to identify challenges in strategic planning and management for health systems in Latin America. This is a longitudinal study with a population base of 187 326 reported cases of older adults with hypertension, diagnosed at public health institutions in Mexico. The cost‐evaluation method that was used was based on the instrumentation and consensus techniques. To estimate the epidemiological changes and financial consequences for 2015–2017, time series analyses and probabilistic models were constructed according to the Box–Jenkins technique. Regarding epidemiological changes for 2015 versus 2017, an increase of 8–12% is expected (p < 0.001). Comparing the economic impact in 2015 versus 2017 (p < 0.001), there is a 22% increase in financial requirements. The total amount estimated for hypertension in 2015 (in US dollars) was $1 575 671 330. It included $747 527 259 as direct costs and $829 144 071 as indirect costs. If the risk factors and the different healthcare services for older adults remain as they are currently, the financial consequences of epidemiological changes in older adults will have a major impact on the users' pockets, following in order of importance, on social security providers and on public assistance providers. The challenges and implications of our findings in the context of universal coverage reforms in Latin America reinforce the urgent need to develop more and better strategic planning for the prevention of chronic diseases.

Awareness and Management of Chronic Disease, Insurance Status, and Health Professional Shortage Areas in the REasons for Geographic and Racial Differences in Stroke (REGARDS): A Cross-Sectional Study

ABSTRACT: BACKGROUND: Limited financial and geographic access to primary care can adversely influence chronic disease outcomes. We examined variation in awareness, treatment, and control of hypertension, diabetes, and hyperlipidemia according to both geographic and financial access to care. METHODS: We analyzed data on 17,458 participants in the REasons for Geographic And Racial Differences in Stroke (REGARDS) study with either hypertension, hyperlipidemia, or diabetes and living in either complete Health Professional Shortage Area (HPSA) counties or non-HPSA counties in the U.S. All analyses were stratified by insurance status and adjusted for sociodemographics and health behaviors. RESULTS: 2,261 residents lived in HPSA counties and 15,197 in non-HPSA counties. Among the uninsured, HPSA residents had higher awareness of both hypertension (adjusted OR 2.30, 95% CI 1.08, 4.89) and hyperlipidemia (adjusted OR 1.50, 95% CI 1.01, 2.22) compared to non-HPSA residents. Also among the uninsured, HPSA residents with hypertension had lower blood pressure control (adjusted OR 0.45, 95% CI 0.29, 0.71) compared with non-HPSA residents. Similar differences in awareness and control according to HPSA residence were absent among the insured. CONCLUSIONS: Despite similar or higher awareness of some chronic diseases, uninsured HPSA residents may achieve control of hypertension at lower rates compared to uninsured non-HPSA residents. Federal allocations in HPSAs should target improved quality of care as well as increasing the number of available physicians.     

Costs and financial consequences of the changing epidemiological profile in Mexico

This article presents an analysis of health-care costs and financial consequences of changes in the epidemiological profile in Mexico. Four tracer diseases were selected to conduct this study: two non-communicable diseases (arterial hypertension and diabetes) and two communicable ones (diarrhea and pneumonia). Costs involved in disease case-management, both in economic and planning terms, predict the internal competition for resources to finance health services for each tracer disease. In addition, the change in the number of cases expected during the study period highlights the process of internal competition and adds an element of intrinsic competition in the management of ambulatory and hospitalized cases for each disease. Study results support the conclusion that if preventive programs remain unchanged, the increasing demands for curative health care may cause great financial and organizational challenges to the health care system of middle-income countries like Mexico.     

Health insurance coverage and the use of preventive services by Mexican adults

The lack of health insurance coverage could be a potentially important deterrent to the use of preventive health care by older adults with high rates of chronic co-morbidities. We use survey data from 12 100 Mexican adults ages 50 and older who participated in the 2001 Mexican Health and Aging Study (MHAS) to analyze the relation between health insurance coverage and the use of preventive health-care services in Mexico. Uninsured adults were less likely to use preventive screenings for hypertension, high cholesterol, diabetes and (breast, cervical and prostate) cancer than insured adults. After adjusting for other factors affecting preventive care utilization in a logistic regression model, we found that these results still hold for high cholesterol and diabetes screening. Similar results hold for the population not working during the survey week and for adults earning below 200% of the poverty line. Our results suggest that insured adults are in a relatively better position to detect some chronic diseases - and have them treated promptly - than uninsured adults because they have better access to cost-effective preventive screenings. Recent public policy initiatives to increase health insurance coverage rates in Mexico could lead to substantially higher preventive health-care utilization rates and improvements in population health.     

Field based evidence of enhanced healthcare utilization among persons insured by micro health insurance units in Philippines

Underutilization of healthcare is common among rural and low-income population segments in countries with lower income or inequitable income distribution. Micro health insurance units (MIUs) are created by informal sector groups because people cannot access health insurance or are dissatisfied with the programmes they can access. The policy choice to support MIUs relies on evidence that affiliation with these schemes increases healthcare utilization. This article examines new evidence of the association between affiliation with MIUs and healthcare utilization. We analyzed field data collected in 6 MIUs in the Philippines in 2002 (through a household survey encompassing 890 insured- and 1063 uninsured households). The two cohorts did not differ in demographic parameters, and differed only marginally in income and education levels, both higher amongst the insured. Insured persons reported higher hospitalization rates, higher rates of professionally-attended deliveries, lower rates of delivery at home, a higher frequency of primary-care physician encounters, a higher rate of diagnosed chronic diseases, and better drug compliance among chronically ill. Increased utilization by the insured is not due to adverse selection, judging by two facts: morbidity of the two cohorts, as assessed by a proxy indicator (the reported number of episodes of illness) did not differ; and rates of deliveries were even slightly higher among the uninsured. We conclude that MIUs in the Philippines can alleviate underutilization of heath care.     

Analysis of hospital charges for cerebral infarction stroke inpatients in Beijing, People's Republic of China

OBJECTIVE: Stroke is a heavy economic burden on the individuals, society and health services in China, where health expenditure is rising rapidly. The purpose of the present study is to examine health services and demographic factors associated with inpatient charges for cerebral infarction in China, focusing on hospital charges of insured and uninsured patients. METHODS: The study subjects were 545 patients with a principal diagnosis of cerebral infarction stroke who were discharged from the China-Japan Friendship Hospital from January 1, 1997 through December 31, 1998. Demographic, clinical and administrative data were retrospectively collected from the medical record and financial database. The influence of social and medical factors on total charges was analyzed with stepwise multiple regression model. RESULTS: Of 545 subjects, 429 (79%) were the insured patients and 116 (21%) were the uninsured patients. Length of hospital stay (LOHS) for the insured patients (median, 32 days) was significantly longer (P<0.001) than that for the uninsured (median, 23 days). The hospital charges per discharge for the insured was significantly higher (geometric mean, 10407 yuan) (P<0.0001) than that for the uninsured patients (geometric mean, 5857 yuan). With stepwise multiple regression, factors associated independently with the hospital charge were: longer hospital stay, insurance status, increased number of head magnetic resonance imaging (MRI) and computerized tomography (CT), infection in hospital stay, and more severe condition of stroke. CONCLUSIONS: Inpatient charge for cerebral infarction stroke was positively associated with being the insured. The findings suggest an overuse of health care resources in insured patients and limited use of resources by those who are not.     

HEALTH SERVICE USE AMONG THE PREVIOUSLY UNINSURED: IS SUBSIDIZED HEALTH INSURANCE ENOUGH?

Although it has been shown that gaining Medicare coverage at age 65 years increases health service use among the uninsured, difficulty in changing habits or differences in the characteristics of previously uninsured compared with insured individuals may mean that the previously uninsured continue to use the healthcare system differently from others. This study uses Medicare claims data linked to two different surveys—the National Health Interview Survey and the Health and Retirement Study—to describe the relationship between insurance status before age 65 years and the use of Medicare‐covered services beginning at age 65 years. Although we do not find statistically significant differences in Medicare expenditures or in the number of hospitalizations by previous insurance status, we do find that individuals who were uninsured before age 65 years continue to use the healthcare system differently from those who were privately insured. Specifically, they have 16% fewer visits to office‐based physicians but make 18% and 43% more visits to hospital emergency and outpatient departments, respectively. A key question for the future may be why the previously uninsured seem to continue to use the healthcare system differently from the previously insured. This question may be important to consider as health coverage expansions are implemented. Copyright © 2011 John Wiley & Sons, Ltd.     

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.     

Losing and acquiring health insurance: consequences for health care

Data from a sample of 5530 Nebraska adults under age 65 are used to analyze the independent correlates of four different insurance statuses: insured 12 consecutive months, uninsured 12 consecutive months, insured at the end of a 12 month period, but not throughout, and uninsured at the end of a 12 month period, but not throughout. The effects of insurance status on utilization of health care services when perceived to be needed are assessed, controlling for demographic explanations. The results show that uninsurance status, whether long-lasting or recent, indicates lower utilization than being insured. Policies designed to expand the number of persons with insurance, especially those linked to practices of insurers, are predicted to have little impact since the underlying causes of uninsurance are related to household income. Lower use of health care services among the uninsured is thought to present financial problems to providers, since the uninsured who do seek care are more likely to need more services (without paying). Problems of higher cost to treat these individuals also present problems for public policies that in effect create subsidies to expand the number of insured. Finally, this study indicates that incremental policy approaches may not deal adequately with the fundamental problems that result in increases in the number of uninsured Americans and caring for their health care needs.     

Uninsured working-age adults: characteristics and consequences.

While estimates of the country's uninsured vary, ranging from 10 to 18 percent of the general population, virtually every study on use of medical services reports that lack of health insurance represents a major barrier to medical care. Based on the 1986 national Robert Wood Johnson Access Survey of 10,130 noninstitutionalized persons, the characteristics of working-age adults without health insurance, and the consequences, are examined. Among working-age adults, the uninsured are most likely to be poor or near-poor, Hispanic, young, unmarried and unemployed. Compared with the insured, they have significantly fewer ambulatory visits during a year, are less likely to have contact with a medical provider during a 12-month period, and are more likely to receive their care in a hospital outpatient clinic or emergency room. Differences in health status do not account for these findings. Especially among persons with chronic and serious illnesses, the uninsured are less likely than the insured to receive medical care. Further, the uninsured are significantly more likely to report needing but not receiving medical care, primarily for economic reasons, and although poorer, they have higher out-of-pocket medical expenses than others in the population.     

Smoking Response to Health and Medical Spending Changes and the Role of Insurance

Severe health shocks provide new information about one's personal health and have been shown to influence smoking behaviors. In this paper, we suggest that they may also convey information about the hard to predict financial consequences of illnesses. Relevant financial risk information is idiosyncratic and unavailable to the consumer preceding illness, and the information search costs are high. However, new and salient information about the health as well as financial consequences of smoking after a health shock may impact smoking responses. Using variation in the timing of health shocks and two features of the US health care system (uninsured spells and aging into the Medicare program at 65), we test for heterogeneity in the post‐shock smoking decision according to plausibly exogenous changes in financial risk exposure to medical spending. We also explore the relationship between smoking and the evolution of out‐of‐pocket costs. Individuals experiencing a cardiovascular health shock during an uninsured spell have more than twice the cessation effect of those receiving the illness while insured. For those uninsured prior to age 65 years, experiencing a cardiovascular shock post Medicare eligibility completely offsets the cessation effect. We also find that older adults' medical spending changes separate from health shocks influence their smoking behavior. Copyright © 2016 John Wiley & Sons, Ltd.     

Health insurance coverage and mortality among the near-elderly

Uninsured near-elderly people may be particularly at risk for adverse health outcomes. We compared mortality of a nationally representative cohort of insured and uninsured near-elderly people with stratification by race; income; and the presence of diabetes, hypertension, or heart disease, using propensity-score methods to adjust for numerous characteristics. Lacking health insurance was associated with substantially higher adjusted mortality among adults who were white; had low incomes; or had diabetes, hypertension, or heart disease. Expanding coverage to the near-elderly uninsured may greatly improve health outcomes for these groups.

Changes in Insurance Status and Access to Care in an Integrated Safety Net Healthcare System

This paper focuses on a cohort of uninsured patients that have accessed outpatient healthcare services in an urban safety net, evaluating the degree to which they switch insurance status and the impact this switching has on access to care. The results indicate that in an integrated safety net system, there is a high frequency of insurance status switching by the uninsured. Uninsured patients who switch to insured status were found to be more likely to visit specialty points of care and less likely to visit urgent points of care than the continuously uninsured. It is well documented that insurance coverage and continuity of care influence health status. Continuity of insurance coverage also has an impact on access to care for those receiving services within a safety net healthcare system.     

Trends and challenges in diabetes for middle-income countries: Evidence from Mexico

The epidemiological and economic burden of diabetes poses one of the main challenges for health systems worldwide. This is particularly relevant in middle-income countries because of the constant growing trends that have been observed in recent years. In order to identify trends and challenges on epidemiological and economic burden from diabetes in a middle-income country we developed a longitudinal analysis on costs and trends in the number of cases of diabetes in Mexico. The study population included total annual cases of diabetes at national level. Regarding the annual cumulative incidence for 2016 versus 2018, depending on the institution there is an increase of 9–13% (p?p?相似文献   

Spillovers and vulnerability: the case of community uninsurance

This paper studies the uninsured as a vulnerable population. We contend that reducing the size of the uninsured population yields important spillover benefits to the insured population, benefits that go beyond a lower charity care burden. Evidence presented in this paper reinforces studies in the literature that show that problems of health services quality and access facing insured people increase when the proportion of uninsured people in their local communities is greater. The size of such spillover benefits is reduced if the local market is large enough to be segmented based on insurance status.     

Children''s Health Insurance Status, Access to and Utilization of Health Services, and Unmet Health Needs in a Rural Alabama School System

PURPOSE: This study examines the relationship between children's health insurance status and utilization of health services, establishment of a medical home, and unmet health needs over a 3-year period (1996-1998) in a rural Alabama K-12 school system. METHODS: As part of a children's health insurance outreach program, questionnaires were administered to parents of 754 children regarding health and health care access. In addition, noninvasive head-to-toe physical assessments of children were conducted on-site at 4 schools. FINDINGS: A relationship between health care utilization and insurance status was observed. Results found that insured children had 1.183 (P < .0115) times the number of medical visits as uninsured children. Among uninsured children, the time since last dental visit was 1.6 (P < .001) times longer than that of insured children. Also, insured children were 5.21 times more likely than uninsured (P < .0001) to report having a medical home. No significant differences between insured and uninsured children were found regarding unmet health needs as measured by referrals made after the children's physical assessments. CONCLUSIONS: Child health coverage is an important determining factor in the ability of families to access and utilize health care services. These findings have implications for populations in similar rural communities across the nation.     

Emergency Room Visits by Uninsured Child and Adult Residents in Ontario,Canada: What Diagnoses,Severity and Visit Disposition Reveal About the Impact of Being Uninsured

Canadian immigrants can be without health insurance for many reasons but limited data exists regarding uninsured health outcomes. Uninsured Canadian residents were identified in the National Ambulatory Care Reporting System for all visits to emergency departments in Ontario, Canada between 2002/3 and 2010/11 (N = 44,489,750). Frequencies for main diagnoses, severity (triage), and visit disposition were compared. Ambulatory care sensitive conditions were identified in a 10 % subsample. The uninsured (N = 140,730; 0.32 %) were more likely to be diagnosed with mental health (insured: 3.48 %; uninsured: 10.47 %) or obstetric problems (insured: 2.69 %; uninsured: 5.56 %), be triaged into the two most severe categories (insured: 11.2 %; uninsured 15.6 %), leave untreated (insured: 3.1 %; uninsured: 5.4 %), or die (insured: 2.8 %; uninsured: 3.7 %). More ACSC visits were made by uninsured children and youth. Insurance status is associated with more serious health status on arrival to emergency departments and more negative visit outcomes.     

Health Insurance and Chronic Conditions in Low-Income Urban Whites

Little is known about how health insurance contributes to the prevalence of chronic disease in the overlooked population of low-income urban whites. This study uses cross-sectional data on 491 low-income urban non-elderly non-Hispanic whites from the Exploring Health Disparities in Integrated Communities—Southwest Baltimore (EHDIC-SWB) study to examine the relationship between insurance status and chronic conditions (defined as participant report of ever being told by a doctor they had hypertension, diabetes, stroke, heart attack, anxiety or depression, asthma or emphysema, or cancer). In this sample, 45.8 % were uninsured, 28.3 % were publicly insured, and 25.9 % had private insurance. Insured participants had similar odds of having any chronic condition (odds ratios (OR) 1.06; 95 % confidence intervals (CI) 0.70–1.62) compared to uninsured participants. However, those who had public insurance had a higher odds of reporting any chronic condition compared to the privately insured (OR 2.29; 95 % CI 1.21–4.35). In low-income urban areas, the health of whites is not often considered. However, this is a significant population whose reported prevalence of chronic conditions has implications for the Medicaid expansion and the implementation of health insurance exchanges.
