Horizontal equity in health care utilization evidence from three high-income Asian economies

This paper compares the extent to which the principle of "equal treatment for equal need"(ETEN) is maintained in the health care delivery systems of Hong Kong, South Korea and Taiwan. Deviations in the degree to which health care is distributed according to need are measured by an index of horizontal inequity. Income-related inequality in utilization is split into four major sources: (i) direct effect of income; (ii) need indicators (self-assessed health status, activity limitation, and age and gender interaction terms); (iii) non-need variables (education, work status, private health insurance coverage, employer-provided medical benefits, Medicaid status (low-income medical assistance), geographic region and urban/rural residency and (iv) a residual term. Service types studied include western doctor, licensed traditional medicine practitioner (LTMP), dental and emergency room (ER) visits, as well as inpatient admissions. Violations of the ETEN principle are observed for physician and dental services in Hong Kong . There is pro-rich inequity in western doctor visits. Unusually, this inequity exists for general practitioner but not specialist care. In contrast, South Korea appears to have almost comprehensively maintained ETEN although the better-off have preferential access to higher levels of outpatient care. Taiwan shows intermediate results in that the rich are marginally more likely to use outpatient services, but quantities of western doctor and dental visits are evenly distributed while there is modest pro-rich bias in the number of LTMP episodes. ER visits and inpatient admissions in Taiwan are either proportional or slightly pro-poor. Future work should focus on the evaluation of policy interventions aimed at reducing the observed unequal distributions.     

Socioeconomic inequalities in health care utilisation in Norway: the population-based HUNT3 survey

ABSTRACT: BACKGROUND: In this study we investigated the distribution of self-reported health care utilisation by education and household income in a county population in Norway, in a universal public health care system based on ideals of equal access for all according to need, and not according to wealth. METHODS: The study included 24,147 women and 20,608 men aged 20 years and above in the third Nord-Trondelag Health Survey (HUNT 3) of 2006--2008. Income-related horizontal inequity was estimated through concentration indexes, and inequity by both education and income was estimated as risk ratios through conventional regression. RESULTS: We found no overall pro-rich or pro-educated socioeconomic gradient in needs-adjusted utilisation of general practitioner or inpatient care. However, we found overall pro-rich and pro-educated inequity in utilisation of both private medical specialists and hospital outpatient care. For these services there were large differences in levels of inequity between younger and older men and women. CONCLUSION: In contrast with recent studies from Norway, we found pro-rich and pro-educated social inequalities in utilisation of hospital outpatient services and not only private medical specialists. Utilisation of general practitioner and inpatient services, which have low access threshold or are free of charge, we found to be equitable.     

Self-referral and self-payment in Danish primary care

This study aims at characterizing the group of people who want to have the right to consult any general practitioner or practising specialist without referral on condition of part self-payment, as opposed to the group of people who choose to be registered with a general practice that offers free services but controls further access to the health care system. All adults or a 10% sample of those listed in nationwide Danish registers were examined cross-sectionally for social and demographic factors and utilization of primary and secondary health care. A minority, which totals 3% of the population, chose free choice of doctor and part self-payment. On average, this group is older and has a higher income. Its mortality and its utilization of general practice and hospital services are lower, and its use of practising specialists is higher, than the majority. Among the persons who chose free choice and self-payment, the pattern of utilization is more likely to be due to a wish for free choice and for specialized medical care than to high morbidity. Dissatisfaction caused by restrictions on self-referral to specialists can be met by offering an option of a parallel system of free choice of doctor on condition of part self-payment.     

Inequities in access to medical care in five countries: findings from the 2001 Commonwealth Fund International Health Policy Survey

OBJECTIVE: To examine across five countries inequities in access to health care and quality of care experiences associated with income, and to determine whether these inequities persist after controlling for the effect of insurance coverage, minority and immigration status, health and other important co-factors. DESIGN: Multivariate analysis of a cross-sectional 2001 random survey of 1400 adults in five countries: Australia, Canada, New Zealand, United Kingdom, and United States. MAIN OUTCOME MEASURES: Access difficulties and waiting times, cost-related access problems, and ratings of physicians and quality of care. RESULTS: The study finds wide and significant disparities in access and care experience between US adults with above and below-average incomes that persist after controlling for insurance coverage, race/ethnicity, immigration status, and other important factors. In contrast, differences in UK by income were rare. There were also few significant access differences by income in Australia; yet, compared to UK, Australians were more likely to report out of pocket costs. New Zealand and Canada results fell in the mid-range of the five nations, with income gaps most pronounced on services less well covered by national systems. In the four countries with universal coverage, adults with above-average income were more likely to have private supplemental insurance. Having private insurance in Australia, Canada, and New Zealand protects adults from cost-related access problems. In contrast, in UK having supplemental coverage makes little significant difference for access measures. Being uninsured in US has significant negative consequences for access and quality ratings. CONCLUSIONS: For policy leaders, the five-nation survey demonstrates that some health systems are better able to minimize among low income adults financial barriers to access and quality care. However, the reliance on private coverage to supplement public coverage in Australia, Canada, and New Zealand can result in access inequities even within health systems that provide basic health coverage for all. If private insurance can circumvent queues or waiting times, low income adults may also be at higher risks for non-financial barriers since they are less likely to have supplemental coverage. Furthermore, greater inequality in care experiences by income is associated with more divided public views of the need for system reform. This finding was particularly striking in Canada where an increased incidence of disparities by income in 2001 compared to a 1998 survey was associated with diverging views in 2001.     

Is inequity undermining Australia's ‘universal’ health care system? Socio‐economic inequalities in the use of specialist medical and non‐medical ambulatory health care

Objectives: To quantify need-adjusted socio-economic inequalities in medical and non-medical ambulatory health care in Australia and to examine the effects of specific interventions, namely concession cards and private health insurance (PHI), on equity.
Methods: We used data from a 2004 survey of 10,905 Australian women aged 53 to 58 years. We modelled the association between socio-economic status and health service use — GPs, specialists, hospital doctors, allied and alternative health practitioners, and dentists — adjusting for health status and other confounding variables. We quantified inequalities using the relative index of inequality (RII) using Poisson regression. The contribution of concession cards and PHI in promoting equity/inequity was examined using mediating models.
Results: There was equality in the use of GP services, but socio-economically advantaged women were more likely than disadvantaged women to use specialist (RII=1.41, 95% CI:1.26–1.58), allied health (RII=1.21,1.12–1.30), alternative health (RII=1.29,1.13–1.47) and dental services (RII=1.61,1.48–1.75) after adjusting for need, and they were less likely to visit hospital doctors (RII=0.74,0.57–0.96). Concession cards reduced socio-economic inequality in GP but not specialist care. Inequality in dental and allied health services was partly explained by inequalities in PHI.
Conclusions and implications: Substantial socio-economic inequity exists in use of specialist and non-medical ambulatory care in Australia. This is likely to exacerbate existing health inequalities, but is potentially amenable to change.     

Socioeconomic patterns in the use of public and private health services and equity in health care

Background  

Several studies in wealthy countries suggest that utilization of GP and hospital services, after adjusting for health care need, is equitable or pro-poor, whereas specialist care tends to favour the better off. Horizontal equity in these studies has not been evaluated appropriately, since the use of healthcare services is analysed without distinguishing between public and private services. The purpose of this study is to estimate the relation between socioeconomic position and health services use to determine whether the findings are compatible with the attainment of horizontal equity: equal use of public healthcare services for equal need.     

Socio-economic status and the utilisation of physicians' services: results from the Canadian National Population Health Survey

This paper assesses the extent to which Canada's universal health care system has eliminated socio-economic barriers in the use of physician services by examining the role of socio-economic status in the differential use of specific, publicly-insured, primary and specialist care services. Data from the 1994 National Population Health Survey, a nationally representative survey, were analysed using multiple logistic regression. In order to control for the association between primary and specialist utilisation, a two-staged least squares method was used for models explaining specialist utilisation. Health need, as measured by perceived health status and number of health problems, was found to be consistently associated with increased physician utilisation, for both primary and specialist visits. Whereas the likelihood of an individual making at least one visit to a primary care physician was found to be independent of income, those with lower incomes were more likely to be frequent users of primary care, that is, make at least six visits to a primary care physician. Even after adjusting for the greater utilisation of primary care services by those in lower socio-economic groups, and, therefore, their higher exposure to the risk of referral, the utilisation of specialist visits was greater for those in higher socio-economic groups. Canadians lacking a regular medical doctor were less likely to receive primary and specialist care, even after adjustments for socio-economic variables such as income and education. Although financial barriers may not directly impede access to health care services in Canada, differential use of physician services with respect to socio-economic status persists. After adjusting for differences in health need, Canadians with lower incomes and fewer years of schooling visit specialists at a lower rate than those with moderate or high incomes and higher levels of education attained despite the existence of universal health care.     

Horizontal inequity in the utilisation of healthcare services in Australia

The Australian universal healthcare system aims to ensure affordable and equitable use of healthcare services based on individual health needs. This paper presents empirical evidence on the extent of horizontal inequity (HI) in healthcare services (unequal utilisation by income for equal need) in Australia during the period of promoting reliance on private healthcare financing. Using data from the most recent Australian National Health Survey of 2011−12 and 2014−15, we examined and measured the extent of HI in eight indicators of out-of-hospital services and hospital-related care. Contrary to earlier studies, our results show a small but pro-rich inequity in the probability of general practitioner visits. Inequity in the distribution of specialist and dentist visits was in favour of richer people, a result that is commonly found in other developed countries and is also consistent with existing Australian evidence. Hospital-related care was equitably distributed compared to the pro-poor pattern found in earlier studies. Despite the universal health insurance system in Australia, there was inequity in the utilisation of needed healthcare services. Our evidence is relevant to similar health systems as governments move to higher out-of-pocket payments and other private sources to reduce pressure on public healthcare expenditure.     

Has access to hospital improved for Aborigines in the Northern Territory?

Abstract: One of the stated aims of Australia's health care system is to achieve equity of access to health care according to need for all Australians, with the ultimate goal of moving toward statistical equality of good health for all. This paper examines how, using routinely collected population health data, we might answer the question of whether access to hospital care for Aborigines in the Northern Territory (NT) improved in relation to access for non-Aborigines during the period 1979 to 1988. Some of the advantages and shortfalls of this approach are discussed and an 'index of access' is postulated. This index is shown to be moving towards 1 during the period, suggesting that access to hospitals has improved for Aborigines compared with non-Aborigines, but that a substantial shortfall still exists. While this index can be useful for measuring progress toward achieving the horizontal equity goal of equal access for equal need, the more difficult task of defining and measuring progress toward vertical equity goals with respect to the persistent and gross inequalities in health status between Aboriginal and non-Aboriginal Australians deserves priority.     

Explaining income-related inequalities in doctor utilisation in Europe

This paper presents new international comparative evidence on the factors driving inequalities in the use of GP and specialist services in 12 EU member states. The data are taken from the 1996 wave of the European Community Household Panel (ECHP). We examine two types of utilisation (the probability of a visit and the conditional number of positive visits) for two types of medical care: general practitioner and medical specialist visits using probit, truncated Negbin and generalised Negbin models. We find little or no evidence of income-related inequity in the probability of a GP visit in these countries. Conditional upon at least one visit, there is even evidence of a somewhat pro-poor distribution. By contrast, substantial pro-rich inequity emerges in virtually every country with respect to the probability of contacting a medical specialist. Despite their lower needs for such care, wealthier and higher educated individuals appear to be much more likely to see a specialist than the less well-off. This phenomenon is universal in Europe, but stronger in countries where either private insurance cover or private practice options are offered to purchase quicker and/or preferential access. Pro-rich inequity in subsequent visits adds to this access inequity but appears more related to regional disparities in utilisation than to other factors. Despite decades of universal and fairly comprehensive coverage in European countries, utilisation patterns suggest that rich and poor are not treated equally.     

Inequalities in access to health care services and utilization for the elderly in São Paulo, Brazil

OBJECTIVE: To describe factors associated to inequalities in access to health care services and utilization for the elderly. METHODS: Study part of the Health, Well-being and Aging in Latin America and the Caribbean ("SABE") Survey that included 2,143 elderly individuals aged 60 or older in the city of S?o Paulo, southeastern Brazil, in 2000. A two-step sampling procedure with probability proportional to size was carried out using census tracts with replacement. To achieve the desired number of respondents aged 75 or older, additional households close to the selected census tracts were sampled. Access to health services and utilization were measured for outpatient and hospital services during a 4-month period prior to the interview, and correlated to factors related to ability, need and predisposition (total income, schooling, health insurance, reported medical condition, self-perception, gender and age).Multivariate logistic regression was performed in the analysis. RESULTS: Of all respondents, 4.7% reported being hospitalized and 64.4% seeking outpatient care in the four months prior to the study. As for public outpatient care provided, 24.7% were in hospital clinics and 24.1% in other public outpatient services. As for private care, 14.5% received care in hospitals and 33.7% in health clinics. The multivariate analysis showed an association between health service utilization and sex, medical condition, self-perceived health, income, schooling, and health insurance. However, an inverse effect was found for the variable "schooling". CONCLUSIONS: The study results show inequalities in access to health services and utilization as well as a deficient health care system. Public policies should take into account the specific needs of the elderly population to facilitate access to health care services and reduce inequalities.     

Access to health care in a system transition: the case of Bulgaria

OBJECTIVE: Throughout the 1990s, the Soviet-style model in central and eastern Europe that provided free health services has been subject to radical reforms. Socio-economic inequalities have also increased but there is little information on inequalities in health care utilization. This paper examines the pattern of illness behaviour in Bulgaria, seeking evidence of inequalities in access to services and eliciting users' pathways to care. DESIGN: Analysis drew on a representative population survey in Bulgaria (1997). The financial determinants of service use were tested in a multivariate model adjusted first for age, and then for age, marital status and self-reported health. In-depth interviews with users and providers addressed pathways to care, use of connections and other informal strategies to obtain care. RESULTS: As expected, rates of illness vary with income, with highest rates among the poor. After adjustment for illness, consultation rates are relatively equal across income levels, with the exception of worse-off women who tend to consult more. For first contact, there are few differences according to income, with the better off preferring secondary level. Pathways slightly differ, with women more often treated in primary care. Private sector utilization is low. Qualitative research reveals well-established strategies to obtain more advanced care, including use of connections, informal payments and use of emergency services. CONCLUSIONS: An apparent lack of inequalities in access to care conceals a more complex picture in which income and gender influence the pathways taken through the system.     

Pathways to care for alcohol use disorders.

BACKGROUND: The aim of the present study was to examine access to care for people with alcohol use disorders. METHOD: An alcohol screening questionnaire was completed by 444 respondents in a community survey. During a designated week, 1009 patients presenting in primary care were assessed by their doctor and 773 of these completed the same questionnaire. Over a six month period 223 people with alcohol use disorders were identified using specialist addiction and psychiatric services, of whom 58 were admitted to hospital. One month prevalence rates of alcohol morbidity were determined for people aged between 16 and 64 years at all five levels in the pathways to care model. RESULTS: Around half the people with alcohol morbidity in the community never consulted their general practitioner and of those who did only half had their problem identified. Case recognition was particularly poor for women, young people and Asians. The main filter to people accessing specialist services came at the point of referral from primary care. This was especially marked for young people and for ethnic minorities. CONCLUSIONS: Strategies are required to improve the identification and treatment of alcohol morbidity in primary care. Deficits in access to specialist services for women, young people and ethnic minorities need to be addressed.     

The poor pay more: Health-related inequality in Thailand

This paper examines the equality of utilization for equal need and equity of out-of-pocket expenditure for health services in a large urban area in Thailand. Data from a household health interview survey were used to explore patterns of perceived morbidity, utilization of various treatment sources, and out-of-pocket payment. Financial access to health care, as reflected in medical benefit/insurance cover, appeared to influence reported illness and hospitalization rates. Gross lack of access to health care amongst lower socio-economic groups was not the main problem in this densely populated urban area because people could choose and use alternative health services according to their ability and willingness to pay. The corollary, however, was an inequitable pattern of out-of-pocket health expenditure by income quintile and per capita. The underprivileged were more likely to pay out of their own pocket for their health problems, and to pay out of proportion to their household income when compared with more privileged groups. Furthermore, the underprivileged were least likely to be covered by government health benefit schemes, in contrast in particular to civil servants, who paid less out of pocket and did not contribute to their medical benefit fund. The private health sector (private clinics and private hospitals) was the major provider of health care to urban dwellers for both outpatient and inpatient services. Policy options for the short and long term to improve the equity of payment systems for health care are discussed.     

The Impact of Accessibility on the Use of Specialist Health Care in Norway

The aim of this study is to explore to what extent the policy goal of allocating health care according to medical need is fulfilled in Norway. Hence, we are interested in studying the impact of a person's health relative to the impact of access to specialist care. We distinguish between services provided by public hospitals and services provided by private specialists financed by the National Insurance Scheme. While a person's self-assessed health plays a major role in the utilization of hospitals, we find no significant effect of this variable on the utilization of private specialists. The accessibility indices for specialist care have significant effects on the utilization of private specialists, but not on hospital visits and inpatient stays. The challenge to policy makers is to consider measures that bring the utilization of publicly funded private specialists in accordance with national health policy.     

Social inequalities in health care services utilisation after eight years of health care reforms: a cross-sectional study of Estonia, 1999

Fundamental health care reforms in Estonia started in 1991 with the introduction of a social health insurance system. While increasing the efficiency of the health care system was one of the targets of the health care reforms, equity issues have received relatively less attention. The objective of this study is to provide an overview of social inequalities in health care utilisation in Estonia in 1999, after 8 years of large-scale reforms. Data were obtained from a nationally representative household interview survey including 3990 respondents aged 25-74 years. Health care utilisation was measured by the telephone consultations, visits to the general practitioner, visits to the specialist, visits to the dentist, and hospitalisation. These utilisation measures were related to variables on ethnicity, place of residence, education, income and employment, by means of direct standardisation and logistic regression models. Three different regression models were applied in order to (a) describe social differences in health care utilisation, (b) to assess whether these differences can be explained by differences in health needs, and (c) to assess the independent effect of each social variable net of all other social variables. Substantial inequalities were observed for all types of health care services and according to most social dimensions. Residents of rural areas were more likely to visit a general practitioner or to use telephone consultation, but less often used outpatient specialist care or dentist care. Ethnic differences were generally smaller, with no consistently higher use by either Russians or ethnic Estonians. Large differences were observed in relation to socio-economic status (education, income, or employment), with a more favourable socio-economic status being associated with higher probability to use health care services, especially after controlling for health needs. In case of hospitalisation, however, no notable social inequalities were found. These findings suggest that important geographic, financial and information barriers to health care utilisation exist after almost one decade of health care reforms in Estonia. Further health care reforms should aim to lessen or even remove these barriers.     

The Influence of Insurance Status and Income on Health Care Use Among the Nonmetropolitan Elderly

The objective of this research is to examine the influence of income and type of insurance coverage on the use of health services among the nonmetropolitan elderly. A model of health services utilization is used as the foundation for examining this issue with data from a telephone survey of a randomly selected sample of residents from four nonmetropolitan counties in Pennsylvania. Results indicated that those elders with Medicaid coverage were less likely to visit a doctor than respondents with private insurance or Medicare only, even after controlling for income and other relevant factors. Further, lower income respondents with Medicare were less likely to visit the dentist than those with private insurance (Medicare does not cover dental care). In contrast, neither income nor insurance predicted hospital use. As such, the health and dental care needs of many lower income nonmetropolitan elders may potentially be going unmet. In general, findings highlight the continued relevance of economic barriers to the use of such services among the nonmetropolitan elderly.     

Private expenditure and the role of private health insurance in Greece: status quo and future trends

The health care system in Greece is financed in almost equal proportions by public and private sources. Private expenditure, consists mostly of out-of-pocket and under-the-table payments. Such payments strongly suggest dissatisfaction with the public system, due to under financing during the last 25 years. This gap has been filled rapidly by the private sector. From this point of view, one might suggest that the flourishing development of private provision may lead in turn to a corresponding growth in private health insurance (PHI). This paper aims to examine the role of PHI in Greece, to identify the factors influencing its development, and to make some suggestions about future policies and trends. In the decade of 1985–1995 PHI show increasing activity, reflecting the intention of some citizens to seek health insurance solutions in the form of supplementary cover in order to ensure faster access, better quality of services, and increased consumer choice. The benefits include programs covering hospital expenses, cash benefits, outpatient care expenses, disability income insurance, as well as limited managed care programs. However, despite recent interest, PHI coverage remains low in Greece compared to other EU countries. Economic, social and cultural factors such as low average household income, high unemployment, obligatory and full coverage by social insurance, lead to reluctance to pay for second-tier insurance. Instead, there is a preference to pay a doctor or hospital directly even in the form of under-the-table payments (which are remarkably high in Greece), when the need arises. There are also factors endogenous to the PHI industry, related to market policies, low organisational capacity, cream skimming, and the absence of insurance products meeting consumer requirements, which explain the relatively low state of development of PHI in Greece.
