Differences in Treatment and Management of Indigenous and Non-Indigenous Patients Presenting with Chest Pain: Results of the Heart Protection Partnership (HPP) Study

BACKGROUND: Indigenous patients with acute coronary syndromes represent a high-risk group. There are however few contemporary datasets addressing differences in the presentation and management of Indigenous and non-Indigenous patients with chest pain. METHODS: The Heart Protection Project, is a multicentre retrospective audit of consecutive medical records from patients presenting with chest pain. Patients were identified as Indigenous or non-Indigenous, and time to presentation and cardiac investigations as well as rates of cardiac investigations and procedures were compared between the two groups. RESULTS: Of the 2380 patients included, 199 (8.4%) identified as Indigenous, and 2174 (91.6%) as non-Indigenous. Indigenous patients were younger, had higher rates hyperlipidaemia, diabetes, smoking, known coronary artery disease and a lower rate of prior PCI; and were significantly less likely to have private health insurance, be admitted to an interventional facility or to have a cardiologist as primary physician. Following adjustment for difference in baseline characteristics, Indigenous patients had comparable rates of cardiac investigations and delay times to presentation and investigations. CONCLUSIONS: Although the Indigenous population was identified as a high-risk group, in this analysis of selected Australian hospitals there were no significant differences in treatment or management of Indigenous patients in comparison to non-Indigenous.

Infertility resolved with or without fertility treatment in Australian women aged 31-36 years: A prospective, population-based study [abstract]

Birth outcomes during a three year period were compared for women with a history of infertility who did or did not use fertility treatment with hormones and/or in vitro fertilisation. Participants in the Australian Longitudinal Study on Women’s Health born in 1973-78 were randomly selected from the universal public health insurance database and completed up to five mailed surveys (1996-2009). Participants reported on their infertility and use of treatment at age 28-33 years (survey 4 (S4) in 2006) and 31-36 years (survey 5 (S5) in 2009). The odds of resolved infertility at S5 were estimated using logistic regression with adjustment for age, area of residence, private health insurance and male infertility. Among 7280 women who responded to both S4 and S5, 18.6% (n=1378) reported infertility. More than half (n=804, 56.8%) of these women did not use treatment and 43.9% (n=347) gave birth between S4 and S5. Compared to infertile women who did not use treatment, women who used treatment were more likely at S5 to have recently given birth (odds ratio (OR) = 1.59, 95% CI 1.26-2.00) or be pregnant (OR = 1.77, 1.27-2.46). Further, women who used treatment were more likely to have twins (3.37, 1.18-9.62), premature births (1.52, 0.95-2.43), or low birthweight babies (1.83, 0.70-2.53) compared to women who gave birth without using treatment. Many women aged up to 36 years with a history of infertility can conceive naturally over a three year period without the use of treatment.Women who have never had a prior birth may need to use treatment to resolve their infertility but they are at higher risk of poorer perinatal outcomes, such as premature or low birthweight babies.

Fertility and infertility : studies in reproductive epidemiology in Australia

Worldwide, there are few large-scale epidemiological studies on infertility. In Australia, population-based research on infertility is limited to a few small-scale studies. Therefore, the prevalence of infertility and unmet need for specialist medical advice and treatment cannot be estimated reliably. Women who have used assisted reproductive technologies (ART) are recorded in treatment registries. However, there are many infertile women who are excluded from these clinical populations because they neither seek advice nor use treatment. The thesis was based on a biopsychosocial model of health and used the methods of reproductive epidemiology to address the lack of national data on the prevalence of infertility in Australia. Firstly, numbers of births and pregnancy losses were investigated in two generations of women participating in the Australian Longitudinal Study on Women’s Health (ALSWH). The ALSWH is a broad-ranging, longitudinal examination of biological, psychological and social factors that impact on women’s health and wellbeing. Women from three age cohorts were randomly sampled from the population using the universal public health insurance (i.e., Medicare) database and ALSWH participants were representative of the female population. However, the studies in the thesis only involved data from two cohorts. The younger cohort were born in 1973-78 and completed up to four mailed surveys between 1996 (when they were aged 18-23 years, n=14247) and 2006 (28-33 years, n=9145). The mid-aged cohort were born in 1946-51 and completed four mailed surveys between 1996 (when they were aged 45-50 years n=13715) and 2004 (53-58 years, n=10905). Compared to other studies that focus on outcomes of single pregnancies, these studies included all pregnancy outcomes by developing comprehensive reproductive histories for each woman. Pregnancy outcomes included birth, miscarriage, stillbirth, termination and ectopic pregnancy. Women in the youngest cohort (born in 1973-78) were only just reaching their peak childbearing years and many (44%) had yet to report their first pregnancy outcome. Women from the mid-aged cohort (born 1946-51) had completed their reproductive lives and 92% were able to report on their lifetime pregnancy outcomes. Pregnancy losses, especially miscarriage, were common for both generations of women. Secondly, the prevalence of infertility, seeking medical advice and using treatment was identified for these two generations of women. For the older generation, the lifetime prevalence of infertility and demand for treatment was investigated in the context of the specialist medical services which became available circa 1980. By this time, however, most of these older women had already been pregnant and completed their families. For women who experienced infertility (11%), their options for advice and treatment were limited and less than half (42%) had used any treatment. More recently for the younger generation of women, who were aged 28-33 years in 2006, specialist advice and treatment were extensively available. Among women who had tried to conceive or had been pregnant (n=5936), 17% had experienced infertility and the majority (72%) were able to access medical advice. However, after seeking advice only half of these infertile women had used treatment with fertility hormones or in vitro fertilisation (IVF). Overall for infertile women aged up to 33 years, only one-third had used these treatments. Thirdly, the barriers to accessing medical advice and using treatment for infertility were identified for women aged less than 34 years. Among a community sample of infertile women aged 28-33 years (ALSWH participants), self-reported depression was found to be a barrier to accessing medical advice. The characteristics of these infertile women in the community who had (n=121) or had not (n=110) used treatment were compared to infertile women aged 27-33 years (n=59) attending four fertility clinics. Compared to infertile women in the community, living in major cities and having private health insurance were associated with early use of treatment for infertility at specialist clinics by women aged <34 years. In contrast to most clinical studies of IVF, the final study reported in the thesis took into account repeated IVF cycles and the impact of women’s individual histories on IVF outcomes. Among 121 infertile women (aged 27-46 years) who had 286 IVF cycles, older age and prolonged use of the oral contraceptive pill were associated with fewer eggs collected. Further, women in particular occupations had lower proportions of eggs fertilised normally than women in other occupational groups. These studies form the first large-scale epidemiological examination of infertility in Australia. The finding that two-thirds of women with infertility had not used treatment indicates that there is an unmet need for specialist treatment in women aged less than 34 years. However, barriers to accessing treatment prevent women using ART at a younger age when there is a higher chance of pregnancy.

The determinants of hiring older workers in Britain revisited: an analysis using WERS 2004

This article reexamines the role of specific human capital and back loading of compensation as deterrents to hiring older workers. We utilize the framework initially suggested by Hutchens (1986) and more recently implemented by Daniel and Heywood (2007). This approach identifies the extent to which firms hire older workers at a rate less than full replacement would imply. Using the 2004 British Workplace Employment Relations Survey, we examine whether a more favourable climate including a much tighter UK labour market combined with the abandonment of defined benefit pension schemes has increased the tendency to hire older workers. We also examine the impact of private health insurance.

Public use and perceptions of emergency departments: A population survey

Objectives To inform demand management strategies aimed at reducing congestion in EDs by: (i) identifying public use of EDs, decision-making and reasons; and (ii) measuring acceptance of alternative care models. Methods A cross-sectional telephone survey of a random sample of Queensland population aged 18 years or older residing in a dwelling unit in Queensland that could be contacted on a land-based telephone service was conducted. One person per household was selected according to a predetermined algorithm to ensure sex and regional balance were interviewed. The main outcome measures were: ED use, attitudes towards ED staff and services, and alternative models of care. Results The final sample included a total of 1256 respondents (response rate = 40.3%). Twenty-one per cent attended EDs in the preceding 12 months. The decision to attend was made by patients (51%), health and medical professionals (31%), and others (18%). The main reasons included perceived severity of the illness (47%), unavailability of alternative services (26%) and better care (11%). Most respondents agreed with more flexible care models of service delivery including incentives for general practitioners (90%), private health insurance coverage for ED use (89%), and enhanced roles for paramedics and nurses. Conclusions Main reason for attending ED is perceived severity of illness, followed by lack of alternative care. The majority of both consumers and the public are in favour of more flexible care models. However, further research is necessary to detail those alternatives and to test and validate their effectiveness.

As transformações da regulação em saúde suplementar no contexto das mudanças do papel do Estado

Esta tese analisa a trajetória, os desafios e as perspectivas da regulação em saúde suplementar, contextualizados num ambiente de grandes transformações do papel dos Estados nacionais e das relações entre a Economia e a Política no âmbito mundial e no Brasil. As interrelações entre economia e política são a base para importantes mudanças no papel do Estado brasileiro, do arcabouço regulatório e da regulação da saúde suplementar em particular. A tese tem início com o desenvolvimento de uma análise sobre o panorama político e econômico mundial, de modo a identificar suas influências sobre o Brasil e o setor de saúde brasileiro. À luz deste arcabouço analítico, é desenvolvido um detalhamento retrospectivo dos principais normativos que compuseram a regulação em saúde suplementar, editados por intermédio da Agência Nacional de Saúde Suplementar ANS. Para tanto, foi construído um banco de dados que servirá não apenas para a pesquisa da tese, mas para outros trabalhos a serem desenvolvidos posteriormente. O estudo desse material permitiu identificar uma trajetória da saúde suplementar marcada por três diferentes tônicas, que tem se desdobrado a partir da cena das grandes transformações mundiais. As conclusões aqui obtidas sobre a trajetória da regulação foram ainda apreciadas, por meio de pesquisa com todos os atuais e antigos dirigentes da ANS. Adiante, foi realizada uma breve análise dos efeitos produzidos por cada uma das tônicas anteriormente descritas, bem como discutidos os principais desafios que se colocam na ordem do dia na agenda da saúde suplementar no Brasil. É interessante destacar que discussão da perspectiva futura da regulação da saúde suplementar no Brasil se dá sobre um pano de fundo de profundas transformações no plano da política e das relações de hegemonia e poder na esfera global. Por fim, o trabalho aqui apresentado tem a finalidade de contribuir para o desenvolvimento do tema e sugerir aperfeiçoamentos de modo a aprimorar o planejamento, a gestão e a regulação da saúde suplementar, buscando relações público-privadas mais harmoniosas e eficientes no tocante à assistência e promoção da saúde.

Empresas promotoras de saúde no sistema de saúde colombiano: dinâmica financeira estrutural.

Esta dissertação analisou as Empresas Promotoras de Salud (EPS), seguradoras de saúde introduzidas no sistema de saúde colombiano através da reforma sanitária instaurada com a Lei n 100/1993, desde uma perspectiva de economia política crítica, através do método de análise documental. A maioria delas são empresas privadas com finalidade lucrativa que conformaram rapidamente um oligopólio que reproduziu problemas dos modelos de Managed Care e Managed Competition já conhecidos internacionalmente. Esta dissertação analisou as relações entre os processos de financeirização do sistema capitalista e o processo de ajuste estrutural na Colômbia, com a reforma sanitária e a dinâmica financeira das EPS. Também foi analisada a introdução de mecanismos próprios do processo de financeirização na gestão financeira das EPS, como: a alavancagem; a reprodução ampliada de capital através da dívida pública; e os investimentos em ativos securitizados. Dado que o sistema de saúde atual se caracteriza por altos níveis de inequidade e injustiça, as consequências da finalidade lucrativa neste, com suas expressões concretas de sofrimento e morte na população, foram preocupações transversais deste trabalho. Os resultados desta dissertação demonstraram a concentração oligopólica do mercado de seguros privados de saúde, cujas empresas se organizaram como um cartel, dificultando o acesso aos serviços de saúde para seus segurados, o que contribuiu para a piora de indicadores de saúde da população. Quando a mobilização social obrigou a aumentar o controle sobre as EPS, estas começaram a sair do mercado declarando-se em falência, ou entrando subitamente em balanços financeiros negativos.

A regulação no mercado de planos de saúde: a ação do consumidor e a estratégia da Agência Nacional de Saúde Suplementar - ANS

The scope of this dissertation is to assess the attitudes of subscribers to private health insurance schemes and the regulatory strategy of the Ancillary National Health Agency -- ANS in relation to their demands. The ancillary health market features various players, each with their own specific interests and priorities. Consequently, the ANS should strive to maintain the balance between the consumers, the economic intermediaries and the State, ensuring that the Agency's powers to establish norms, as well as to regulate and to supervise each be exercised independently. Many people contend that there are elements not currently incorporated into the current services of the ANS which could contribute to its regulatory strategy. This study was conducted from the standpoint of theories applied to State administration for structural analysis of the ANS and its strategies, in addition to a symbolic and rational approach for a better understanding of the consumers involved. A survey was conducted of existing records of the ANS, as well as data collected from direct observation. Analysis of the data obtained led to the conclusion that the consumer can become a close ally in the regulatory activity of the ANS, to the extent that the latter may acquire more in-depth knowledge of aspects contained in the demands of the former.

Análise do desempenho econômico-financeiro de operadoras de planos de saúde no mercado de saúde suplementar brasileiro

O mercado privado de planos de saúde tem sido marcado por aumento dos custos da assistência médica, ampliação da cobertura de procedimentos, restrições nos reajustes dos planos e aumento das garantias de solvência exigidas pela Agência Nacional de Saúde Suplementar (ANS), impactando o desempenho econômico-financeiro das operadoras de planos de saúde. A presente dissertação tem como objetivo analisar o desempenho econômico-financeiro de operadoras das modalidades autogestão, cooperativa médica, medicina de grupo e seguradora no período de 2001 a 2012. Foi utilizada uma base de dados operacionais e contábeis disponível na página eletrônica da ANS, com 5.775 observações, avaliando-se o desempenho econômico-financeiro por meio de cinco indicadores: Retorno sobre Ativos, Retorno Operacional sobre Ativos, Retorno sobre o Patrimônio Líquido, Liquidez Corrente e Sinistralidade. Dois modelos hierárquicos foram adotados para estimar os efeitos operadora, modalidade e porte no desempenho. Dentre estes, a pesquisa identificou que o efeito operadora é responsável pela maior parte da variabilidade explicada do desempenho. A investigação permitiu identificar as operadoras que apresentaram melhor desempenho no período, direcionando a realização futura de estudos qualitativos visando conhecer os principais fatores que explicam o desempenho superior.

Comparando a saúde no Brasil com os países da OCDE: explorando dados de saúde pública

A atenção à saúde da população no Brasil gera um grande volume de dados sobre os serviços de saúde prestados. O tratamento adequado destes dados com técnicas de acesso à grande massa de dados pode permitir a extração de informações importantes para um melhor conhecimento do setor saúde. Avaliar o desempenho dos sistemas de saúde através da utilização da massa de dados produzida tem sido uma tendência mundial, uma vez que vários países já mantêm programas de avaliação baseados em dados e indicadores. Neste contexto, A OCDE – Organização para Cooperação e Desenvolvimento Econômico, que é uma organização internacional que avalia as políticas econômicas de seus 34 países membros, possui uma publicação bienal, chamada Health at a Glance, que tem por objetivo fazer a comparação dos sistemas de saúde dos países membros da OCDE. Embora o Brasil não seja um membro, a OCDE procura incluí-lo no cálculo de alguns indicadores, quando os dados estão disponíveis, pois considera o Brasil como uma das maiores economias que não é um país membro. O presente estudo tem por objetivo propor e implementar, com base na metodologia da publicação Health at a Glance de 2015, o cálculo para o Brasil de 22 indicadores em saúde que compõem o domínio “utilização de serviços em saúde” da publicação da OCDE. Para isto foi feito um levantamento das principais bases de dados nacionais em saúde disponíveis que posteriormente foram capturadas, conforme necessidade, através de técnicas para acessar e tratar o grande volume de dados em saúde no Brasil. As bases de dados utilizadas são provenientes de três principais fontes remuneração: SUS, planos privados de saúde e outras fontes de remuneração como, por exemplo, planos públicos de saúde, DPVAT e particular. A realização deste trabalho permitiu verificar que os dados em saúde disponíveis publicamente no Brasil podem ser usados na avaliação do desempenho do sistema de saúde, e além de incluir o Brasil no benchmark internacional dos países da OCDE nestes 22 indicadores, promoveu a comparação destes indicadores entre o setor público de saúde do Brasil, o SUS, e o setor de planos privados de saúde, a chamada saúde suplementar. Além disso, também foi possível comparar os indicadores calculados para o SUS para cada UF, demonstrando assim as diferenças na prestação de serviços de saúde nos estados do Brasil para o setor público. A análise dos resultados demonstrou que, em geral, o Brasil comparado com os países da OCDE apresenta um desempenho abaixo da média dos demais países, o que indica necessidade de esforços para atingir um nível mais alto na prestação de serviços em saúde que estão no âmbito de avaliação dos indicadores calculados. Quando segmentado entre SUS e saúde suplementar, a análise dos resultados dos indicadores do Brasil aponta para uma aproximação do desempenho do setor de saúde suplementar em relação à média dos demais países da OCDE, e por outro lado um distanciamento do SUS em relação a esta média. Isto evidencia a diferença no nível de prestação de serviços dentro do Brasil entre o SUS e a saúde suplementar. Por fim, como proposta de melhoria na qualidade dos resultados obtidos neste estudo sugere-se o uso da base de dados do TISS/ANS para as informações provenientes do setor de saúde suplementar, uma vez que o TISS reflete toda a troca de informações entre os prestadores de serviços de saúde e as operadoras de planos privados de saúde para fins de pagamento dos serviços prestados.

Caminhos da política de saúde no Brasil: determinantes da “universalização excludente” em curso

O interesse deste estudo foi, de modo geral, poder identificar como o modelo privatista influenciou as ações da política pública de saúde no Brasil, como se deram os impactos da política macroeconômica neste sentido. Um dos pontos chave a ser verificado gira em torno da desigualdade de acesso da população ao serviço de saúde, com a não concretização da universalidade, gerando um processo denominado “universalização excludente”. Esse processo que consiste na migração de usuários do SUS para as operadoras de planos de saúde privados contribui para a mudança da racionalidade da saúde como direito para a racionalidade da eficiência, a racionalidade burguesa. Parte-se do referencial da Reforma Sanitária brasileira, como um marco da luta dos movimentos sociais pela democratização no país e como ponto inicial do reconhecimento da saúde enquanto direito de todos e dever do Estado, buscando fazer um resgate histórico deste movimento. Tem, ainda, como referência o pressuposto da minimização da atuação do Estado no trato às políticas sociais e a interferência direta de grandes organismos financeiros internacionais na condução do modo de fazer política de saúde, a exemplo do Banco Mundial. Esta consiste em uma pesquisa qualitativa, de cunho teórico, com o objetivo de proporcionar subsídios para a discussão do tema da política de saúde no Brasil, bem como promover e ampliar o debate teórico acerca da função que o Estado desempenha no modo de pensar e executar essa política.

Contextual and individual inequalities in dental pain prevalence among Brazilian adults and elders

This study aimed to assess the prevalence of dental pain among adults and older people living in Brazil's State capitals. Information was gathered from the Telephone Survey Surveillance System for Risk and Protective Factors for Chronic Diseases (VIGITEL) in 2009 (n = 54,367). Dental pain was the outcome. Geographic region, age, gender, race, schooling, private health coverage, smoking, and soft drink consumption were the explanatory variables. Multilevel Poisson regression models were performed. Prevalence of dental pain was 15.2%; Macapa and Sao Luis had prevalence rates greater than 20%; all capitals in the South and Southeast, plus Cuiaba, Campo Grande, Maceio, Recife, and Natal had prevalence rates less than 15%. Factors associated with increased prevalence of dental pain were the North and Northeast regions, female gender, black/brown skin color, lack of private health insurance, smoking, and soft drink consumption. Dental pain is a public health problem that should be monitored by health surveillance systems.

Barriers to Timely Screening Colonoscopy

Objective: Colorectal cancer (CRC) can be largely prevented or effectively treated in its early stages, yet disparities exist in timely screening. The aim of this study was to explore the disparities in CRC screening on the basis of health insurance status including private, Medicare, Medicaid, and State Administered General Assistance (SAGA). Methods: A retrospective chart review for the period January 2000 to May 2007 (95 records) was conducted at two clinic sites; a private clinic and a university hospital clinic. All individuals at these sites who met study criteria (>50 years old with screening colonoscopy) were included. Age, gender, date of first clinic visit when screening referral was made, and date of completed procedure (screening colonoscopy) were recorded. Groups were dichotomized between individuals with private health insurance and individuals with public health insurance. Individuals with any history of CRC, known pre-cancerous conditions as well as family history of CRC requiring frequent colonoscopy were excluded from the study. Linear model analysis was performed to compare the average waiting time to receiving screening colonoscopy between the groups. T-test was performed to analyze age or gender related differences between the two groups as well as within each group. Results: The average waiting time (33 days) for screening colonoscopy in privately insured individuals was significantly lower than publicly insured individuals (200 days). The time difference between the first clinic visit and the procedure was statistically significant (p < 0.0001) between the two groups. There was no statistical difference (p=0.089) in gender between these groups (public vs. private). There were also no statistically significant gender or age related differences found within each group. Conclusions: Disparities exist in timely screening for CRC and one of the barriers leading to delayed CRC screening includes health insurance status of an individual. Even within the insured group, type of insurance plays major role. There is a negative correlation between public health insurance status and timely screening. Differences in access to medical care and delivery of care experienced by patients who are publicly insured through Medicaid, Medicare, and SAGA, suggests that the State of Connecticut needs to implement changes in health care policies that would provide timely screening colonoscopy. It is evident that health insurance coverage facilitates timely access to healthcare. Therefore, there is a need for increased efforts in advocacy for policy, payment and physician participation in public insurance programs. A state-wide comprehensive program involving multiple components targeting different levels of change such as provider, patients and the community should help reduce some of the observed causes of healthcare disparities based on the insurance status.

PREVALENCE AND FACTORS ASSOCIATED WITH THE PERFORMANCE OF MAMMOGRAPHY AND PAP SMEAR TEST

Objective: To estimate the prevalence and factors associated with the performance of mammography and pap smear test in women from the city of Maringá, Paraná. Methods: Population-based cross-sectional study conducted with 345 women aged over 20 years in the period from March 2011 to April 2012. An interview was carried out using a questionnaire proposed by the Ministry of Health, which addressed sociodemographic characteristics, risk factors for chronic noncommunicable diseases and issues related to mammographic and pap screening. Data were analyzed using bivariate analysis, crude analysis with odds ratio (OR) and chi-squared test using Epi Info 3.5.1 program; multivariate analysis using logistic regression was performed using the software Statistica 7.1, with a significance level of 5% and a confidence interval of 95%. Results: The mean age of the women was 52.19 (±5.27) years. The majority (56.5%) had from 0 to 8 years of education. Additionally, 84.6% (n=266) of the women underwent pap smear and 74.3% (n=169) underwent mammography. The lower performance of pap smear test was associated with women with 9-11 years of education (p=0.01), and the lower performance of mammography was associated with women without private health insurance (p<0.01). Conclusion: The coverage of mammography and pap smear test was satisfactory among the women from Maringá, Paraná. Low education level and women who depended on the public health system presented lower performance of mammography.

Going public : do risk and choice explain differences in caesarean birth rates between public and private places of birth in Australia?

Background: Women who birth in private facilities in Australia are more likely to have a caesarean birth than women who birth in public facilities and these differences remain after accounting for sector differences in the demographic and health risk profiles of women. However, the extent to which women’s preferences and/or freedom to choose their mode of birth further account for differences in the likelihood of caesarean birth between the sectors remains untested. Method: Women who birthed in Queensland, Australia during a two-week period in 2009 were mailed a self-report survey approximately three months after birth. Seven hundred and fifty-seven women provided cross-sectional retrospective data on where they birthed (public or private facility), mode of birth (vaginal or caesarean) and risk factors, along with their preferences and freedom to choose their mode of birth. A hierarchical logistic regression was conducted to determine the extent to which maternal risk and freedom to choose one’s mode of birth explain sector differences in the likelihood of having a caesarean birth. Findings: While there was no sector difference in women’s preference for mode of birth, women who birthed in private facilities had higher odds of feeling able to choose either a vaginal or caesarean birth, and feeling able to choose only a caesarean birth. Women had higher odds of having caesarean birth if they birthed in private facilities, even after accounting for significant risk factors such as age, body mass index, previous caesarean and use of assisted reproductive technology. However, there was no association between place of birth and odds of having a caesarean birth after also accounting for freedom to choose one’s mode of birth. Conclusions: These findings call into question suggestions that the higher caesarean birth rate in the private sector in Australia is attributable to increased levels of obstetric risk among women birthing in the private sector or maternal preferences alone. Instead, the determinants of sector differences in the likelihood of caesarean births are complex and are linked to differences in the perceived choices for mode of birth between women birthing in the private and public systems.
