RESUMO

OBJECTIVES: to evaluate the trends in cesarean sections from 2014 to 2020 across both public and private sectors, utilizing the Robson Classification. METHODS: this time series study analyzed the proportion of women who underwent cesarean sections between 2014 and 2020, considering both the Robson classification and the type of healthcare service. Trend analysis was conducted using the Prais-Winsten regression. RESULTS: higher proportions of cesarean sections were observed in all Robson groups within the private sector compared to the public sector. This was despite a decreasing trend in the private sector and an increasing trend in the public sector. Notably, elevated proportions of cesarean sections were recorded in groups that are typically favorable to normal childbirth (Robson 1, 4, and 5). CONCLUSIONS: although there was a decreasing trend in cesarean sections within the private sector, an increasing trend was observed in the public sector. Additionally, there was a high proportion of cesarean sections among women with conditions favorable to normal childbirth. It is crucial to continuously monitor these indicators to evaluate and implement interventions aimed at reducing unnecessary cesarean sections.

RESUMEN Objetivos: analizar las acciones judiciales iniciadas por beneficiarios de planes de salud de prepago. Métodos: estudio descriptivo, transversal, desarrollado en importante operadora de planes de salud de prepago, utilizando datos recopilados por la empresa entre 2015 y 2015. Resultados: fueron impulsadas 96 acciones judiciales por parte de 86 beneficiarios, referentes a procedimientos médicos (38,5%), tratamientos (26,1%), estudios (14,6%), medicación (9,4%), Home Care (6,2%) y 5,2% por otros tipos de internación. La mayoría de acciones por procedimientos correspondió a rizotomía percutánea; en tratamientos, a quimioterapia; en estudios, a tomografía por emisión de positrones; en medicamentos, a antineoplásicos y para tratar la hepatitis C. Conclusiones: motivaron las acciones judiciales interpuestas la negativa de la operadora de planes de salud a cubrir prestaciones no incluidas en el alcance del plan contratado por el beneficiario, así como asuntos no reglados y autorizados por la Agencia Nacional de Salud Complementaria, considerándose, en consecuencia, improcedentes.

RESUMO

Alarming data on the part of health care providers on the increase of the claim rate and its potential risk has emerged. It is a descriptive study, with the objective of understanding the changes in the healthcare provider sector in recent years, using the temporal analysis of historical series related to the sector. The variables selected for this study were the claim rate, the coverage rate, and the number of private healthcare providers in activity, observed from 2003 to 2014. The method used for evaluation of the temporal trend was Linear Regression. The claim rate and the coverage rate show an upward trend in the period, while the number of operators in Brazil showed a decreasing trend during the same period. These results show that even with the increase in demand, there was a decrease in the number of operators active in the country. The claim rate is one of the possible causes observed this inverse relationship because the increased offers risks of survival and the opening of new operators. Moreover, the decrease in the number of providers, is leading the country to an oligopolistic industry with an increasing demand in the number of beneficiaries. This decrease is also associated with regulatory processes, which regulates the sector's relationship with the beneficiary.

Dados alarmantes vêm surgindo por parte das operadoras de saúde sobre o aumento da sinistralidade e seu potencial risco. Estudo descritivo, com o objetivo de compreender as mudanças ocorridas no setor de saúde suplementar nos últimos anos, através da análise temporal de séries históricas relacionadas ao setor. As variáveis escolhidas para este trabalho foram a sinistralidade, a taxa de cobertura e o quantitativo de operadoras em atividade, observadas de 2003 a 2014. O método utilizado para a avaliação da tendência temporal foi a Regressão Linear. A sinistralidade e a taxa de cobertura apresentaram uma tendência de crescimento no período, enquanto a quantidade de operadoras no Brasil apresentou uma tendência de decrescimento no mesmo período. Esses resultados apontam que, mesmo com o aumento da demanda, houve uma diminuição do número de operadoras em atividade no país. A sinistralidade é uma das possíveis causas de observarmos essa relação inversa, pois o seu aumento oferece riscos à sobrevida e à abertura de novas operadoras. Ademais, a diminuição do número de operadoras está conduzindo o país a uma oligopolização do setor com uma demanda crescente do número de beneficiários. Essa diminuição pode estar também associada aos processos regulatórios que normatizam a relação do setor com o beneficiário.

RESUMO

Significant changes have been witnessed in the Brazilian health system over the last 30 years. This article outlines trends in outpatient and hospital care, staffing, and health service use during this period. There was a significant expansion of the public health network, particularly of primary care services, leading to improved access to consultations and a reduction in hospital admissions. However, there is a persistent shortage of health professionals in Brazil's public health system, particularly dentists. Despite improvements in coverage, the public system continues to face serious challenges, particularly with respect to funding, service provision, and its relationship with the private sector.

Ao longo dos últimos 30 anos, o Sistema Único de Saúde brasileiro se caracterizou por importantes mudanças na atenção à saúde. No presente artigo, são apresentados dados relativos à evolução das estruturas ambulatorial e hospitalar, e dos recursos humanos, bem como acerca da utilização dos serviços de saúde. A expansão da rede pública ocorreu principalmente entre as unidades que dão suporte aos programas de atenção básica, ampliando o acesso às consultas médicas e a redução das internações para um conjunto de doenças, mas persiste uma carência de profissionais, especialmente no cuidado odontológico. Entretanto, a despeito do avanço na cobertura, permanecem os desafios à continuidade do SUS e à melhoria da qualidade do cuidado, particularmente no tocante ao financiamento público, oferta de serviços, e na relação com o setor privado.

RESUMO

CONTEXT AND OBJECTIVE Orthopedic surgery implies high costs for both public and private healthcare. The aim of this study was to better understand the differences between the public and private sectors regarding treatment of a damaged anterior cruciate ligament, which is a common knee injury. DESIGN AND SETTING Descriptive cross-sectional study conducted during the Brazilian Orthopedics Congress in Brasília. METHODS We applied questionnaires during the 2010 Brazilian Orthopedics Congress, with participation by 241 knee surgeons from 24 Brazilian states. This was followed by statistical analysis on the data that were obtained. RESULTS The orthopedic surgeons who were evaluated used different approaches and treatment options in different Brazilian states, comparing between the public and private systems. CONCLUSION Both in the public and in the private systems in Brazil, because of non-medical issues surrounding the treatment, the best medical decision is not always made. This may be harmful both to patients and to physicians.

RESUMO

PURPOSE: The objective of this study is to identify how risk and social variables are likely to be impacted by an increase in private sector participation in health insurance provision. The study focuses on the Chilean health insurance industry, traditionally dominated by the public sector. DESIGN/METHODOLOGY/APPROACH: Predictive risk modelling is conducted using a database containing over 250,000 health insurance policy records provided by the Superintendence of Health of Chile. FINDINGS: Although perceived with suspicion in some circles, risk segmentation serves as a rational approach to risk management from a resource perspective. The variables that have considerable impact on insurance claims include the number of dependents, gender, wages and the duration a claimant has been a customer. PRACTICAL IMPLICATIONS: As shown in the case study, to ensure that social benefits are realised, increased private sector participation in health insurance must be augmented by regulatory oversight and vigilance. ORIGINALITY/VALUE: As it is clear that a "community-rated" health insurance provision philosophy impacts on insurance firm's ability to charge "market" prices for insurance provision, the authors explore whether risk segmentation is a feasible means of predicting insurance claim behaviour in Chile's private health insurance industry.
