ABSTRACT INTRODUCTION Health systems are one determinant of health; their role is to facilitate timely and equitable access to quality services. The way in which a health system is organized can profoundly affect achievement of its objectives. The main feature of the Chilean health system is the coexistence of a public health insurance program (based on a social insurance model) with several market-based private health insurance companies. This hybrid structure provides an interesting framework for analyzing and evaluating the system’s effects on health inequalities. OBJECTIVE Assess Chilean public and private health insurance schemes’ performance and its effects on health inequalities. METHODS Public health insurance was compared with private insurance using indicators from 2013 (or the closest year) in the following domains: inputs, outputs (provider visits, discharges), outcomes (coverage) and impact (on health, quality of life, finances and patient satisfaction) as well as demographic and social determinant indicators. A conceptual framework for measuring health system performance was used. Data were obtained from administrative records and population-based surveys. RESULTS The publicly insured population had greater health care needs, was older (aging index 83.4 vs. 36.5) and poorer (17.2% vs. 1.5% below the poverty line) than the population covered by private insurers. The public insurer received average monthly funding of US$50.94 per beneficiary and spent US$51.43, while private insurers on average collected US$94.79 monthly per beneficiary, and spent US$69.63 on health services (excluding medical leave benefits). Private health insurance beneficiaries were more likely than their publicly insured counterparts to access specialized medical services (18.3% vs. 9.3%) and dentists (11.2% vs. 5.9%), have laboratory tests (18.1% vs. 4.8%), and undergo surgery (7.8% vs. 5.9%). Risk factor and disease prevalence was lower among private insurance beneficiaries for 16 of 18 tracer conditions, although age-adjusted differences were not significant. Finally, incidence of catastrophic spending was slightly lower among private insurance beneficiaries (3.7% vs. 4.2%), and a greater proportion of them were satisfied or very satisfied with the health system (37% vs. 17%). CONCLUSIONS The relative youth and better financial status of beneficiaries of private insurers is compatible with selection for lower risk. While private plans offer greater financial protection and receive higher user satisfaction ratings than the public plan, differences in financing between the two types of insurance affect availability and utilization of services. This constitutes a structural problem for the Chilean health system. There is an urgent need to move toward an integrated health system, in which incentives are aligned with social insurance objectives.

Introduction: Meningococcal disease (MD) is a major global problem because of its case fatality rate and sequels. Since 2012 cases of serogroup W have increased in Chile, with nonspecific clinical presentation, high case fatality rate and serious consequences. Objective: To characterize the evolution and outcome of MD cases between January 2012 and March 2013 in Chile. Material and Methods: Case series considering149 MD cases of 7 regions. A questionnaire was applied and clinical records were reviewed, including individual, agent, clinical course and healthcare process variables. The analysis allowed to obtain estimates of the OR as likelihoodof dying. Results: 51.5% was meningococcemia, the case fatality rate reached 27%, prevailing serogroup W (46.6%). Factors that increased the probability of dying: > age, belonging to indigenous people, having lived a stressful event, having diarrhea, impaired consciousness, cardiovascular symptoms, low oxygen saturation and low Glasgow coma scale score. Discussion: The case fatality rate exceeded normal levels and was higher in serogroup W. Increasing in this serogroup, associated to the increased presence of nonspecific symptoms or rapid progression to septicemia, hit a health system accustomed to more classic meningococcal disease presentation, which could partly explain the observed increased fatality rate.

Introducción: La enfermedad meningocóccica (EM) es un importante problema mundial por su letalidad y secuelas. Desde 2012 aumentaron en Chile los casos por serogrupo W, con presentación clínica inespecífica, elevada letalidad y secuelas graves. Objetivo: Caracterizar la evolución y desenlace de EM en casos desde enero de 2012 a marzo de 2013 en Chile. Material y Método: Serie de 149 casos de EM de siete regiones. Se aplicó un cuestionario y se revisaron registros clínicos, incluyendo variables del individuo, agente, curso clínico y proceso de atención. Los análisis permitieron obtener OR como estimadores de la probabilidad de fallecer. Resultados: El 51,5% se presentó como meningococcemia, la letalidad alcanzó a 27%, predominando el serogrupo W (46,6%). Aumentaron la probabilidad de fallecer: una mayor edad, pertenencia a pueblos originarios, haber vivido evento estresante, presentar diarrea, compromiso de conciencia, síntomas cardiovasculares, baja saturación de oxígeno y bajo puntaje de Glasgow. Discusión: La letalidad superó las frecuencias habituales y fue mayor en el serogrupo W. El aumento de este serogrupo, asociado a la mayor presencia de síntomas inespecíficos o a la rápida progresión a septicemia, impactó en un sistema de salud habituado a cuadros más clásicos de EM, lo que podría explicar en parte, la mayor letalidad observada.

Introduction: The Chilean Ministry of Health (MINSAL) and the Chilean Federation of Bakers (FECHIPAN) agreed to progressively decrease sodium content in bread from 800 to 500 mg/100 g bread in 100 bakeries in 2011 and in 100% of bakeries in 2014. Objective: To analyze and compare the sodium content in bread from a bakery with national distribution (A) and a local bakery (B). Materials and methods: A total of 100 samples were analyzed in each bakery 50 each of the two types of bread known as marraqueta and hallulla (types of bread rolls). Analysis was performed at different times of the day and at different days of the week. Sodium content was determined by the AOAC (2005) method using atomic absorption spectrophotometry and compared with the sodium content declared in the nutrition label in bakery A. Differences between content for type of bread, bakery and time of sampling were established by ANOVA and Student's t-test with the STATA 12.0 software at a p<0.05 level of significance. Results: Total sodium in bread (mg/100 g unit) was estimated as 619.6±127.7 mg for hallulla and 641.0±93.3 for marraqueta. There were no significant differences in sodium content in both bakeries (p=0.971) and type of bread (p=0.177). Sodium content was higher on Wednesdays (p<0.0001, p=0.016) and at 17 hours (p<0.000001, p=0.028) in hallulla and marraqueta, respectively. Total sodium content in both bakeries varied between 412.5 and 954.5 mg/100 g. Conclusions: Bread from both bakeries showed similar sodium contents although they exceeded the MINSAL-FECHIPAN agreement by 26% to 80%.

Introducción: El Ministerio de Salud de Chile (MINSAL) y la Federación de Panaderos de Chile (FECHIPAN) acordaron reducir progresivamente el contenido de sodio en el pan de 800 mg a 500 mg/100 g pan, en 100 panaderías el 2011 y en 100% de ellos el año 2014. Objetivo: Analizar el contenido de sodio en pan de una panadería de distribución nacional (A) comparada con una de tipo local (B). Materiales y métodos: Se analizaron 100 muestras de pan por panadería, 50 de marraqueta y 50 de hallulla, en diferentes horas y días de la semana. El contenido de sodio se determinó con el método AOAC (2005) mediante espectrofotometría de absorción atómica y se comparó con el contenido de sodio declarado en el etiquetado nutricional de la panadería A. Se utilizó ANOVA y T-student para establecer diferencias del contenido de sodio por tipo de pan, panadería y hora de extracción, utilizando el software STATA 12.0 con un nivel de significancia p<0,05. Resultados: El sodio total en el pan (mg/100 g pan) se estimó en 619,6±127,7 mg para hallulla y 641±93,3 para marraqueta, sin diferencias significativas para su contenido en ambas panaderías (p=0,971) y tipo de pan (p=0,177). El sodio fue mayor el día miércoles (p<0,0001 - p=0.016) y a las 17 horas (p<0,000001 - p=0.028) en pan hallulla y marraqueta respectivamente. Con variabilidad en el contenido de sodio total en ambas panaderías entre 412,5 a 954,5 mg/100 g. Conclusiones: El pan de ambas panaderías presenta similar contenido de sodio pero excediéndose 26% a 80% del acuerdo MINSAL-FECHIPAN.

Objective. Analyze barriers and facilitators of access to prenatal care in pregnant urban adolescents between 15-19 years of age in Santiago, Chile. Materials and methods. Qualitative study based on grounded theory with 17 adolescent mothers. Eleven semi-structured interviews and one focus group were conducted. Results. The denial and concealment of pregnancy is the main barrier to start the prenatal care in the "delayed access group". This group does not identify facilitators. For maintenance in antenatal care, all participants identified a support figure as a facilitator. Family and social vulnerabilities explain why some adolescents start the prenatal care late. Conclusion. The presence of facilitators is crucial for both, the timely entry and the maintenance in antenatal care because they reduce or nullify the effect of barriers. The health system must become a facilitator to accompany adolescents and promote a bond of trust and respect.

Objetivo. Analizar barreras y facilitadores de acceso a control prenatal en adolescentes urbanas de 15-19 años en Santiago, Chile. Material y métodos. Estudio cualitativo con 17 madres adolescentes basado en la teoría fundamentada. Se realizaron 11 entrevistas semiestructuradas y un grupo focal. Resultados. La negación y ocultamiento del embarazo es la principal barrera para ingresar a control en el grupo de acceso tardío; no se identificaron facilitadores. Para mantenerse en control, todas las participantes identifican como facilitador contar con una figura de apoyo. La vulnerabilidad familiar y social explica que algunas adolescentes ingresen a control tardíamente. Conclusión. La presencia de facilitadores es determinante para el ingreso oportuno y mantenerse en control, ya que reduce o anula el efecto de las barreras. El sistema de salud debe constituirse en un facilitador que acompañe desde muy temprano a las adolescentes favoreciendo un vínculo de confianza y respeto.

OBJECTIVE: To determine whether health care access barriers and facilitators cut across different populations, countries, and pathologies, and if so, at which stages of health care access they occur most frequently. METHODS: A qualitative systematic review of literature published between 2000 and 2010 was undertaken drawing on six international sources: Fuente Académica, MEDLINE (full-text), Academic Search Complete (a full-text multidisciplinary academic database), PubMed, SciELO, and LILACS. Scientific appraisal guidelines from the Critical Appraisal Skills Programme Español (CASPe) and Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) were applied. Gray literature was also reviewed. RESULTS: From the review of scientific literature, 19 of 1 160 articles and 8 of 12 gray literature documents were selected. A total of 230 barriers and 35 facilitators were identified in countries with different contexts and degrees of development. The 230 barriers were classified according to the Tanahashi framework: 25 corresponded to availability, 67 to access, 87 to acceptability, and 51 to contact. Most of the barriers were related to acceptability and access. The facilitating elements that were identified had to do with personal factors, the provider-client relationship, social support, knowledge about diseases, and adaptation of the services to patients. CONCLUSIONS: The barriers and facilitators were seen mostly in people who initiated contact with the health systems, and they occurred at all stages of health care access. Only a few of the studies looked at people who did not initiate contact with the health services. The barriers and facilitators identified were socially determined and largely a reflection of existing social inequities in the countries. To reduce or eliminate them, joint action with other non-health sectors will be necessary.

OBJETIVO: Determinar si las barreras y los elementos facilitadores de acceso a la atención de salud son transversales a distintas poblaciones, países y patologías, e identificar en qué etapas del proceso de acceso a la atención sanitaria se presentan con más frecuencia. MÉTODOS: Revisión sistemática cualitativa de literatura publicada durante el período 2000-2010. Se consultaron seis fuentes internacionales: Fuente Académica, Medline en texto completo, Base de datos académica multidisciplinaria en texto completo (Academic Search Complete), PubMed, SciELO y LILACS. Se aplicaron criterios de valoración científica del Programa CASPe y la declaración STROBE. En paralelo se revisó literatura gris. RESULTADOS: Se seleccionaron 19 de 1 160 resultados de la revisión de artículos científicos, y 8 de 12 documentos de la revisión de literatura gris. Se identificaron 230 barreras y 35 facilitadores en países con diferentes contextos y grados de desarrollo. Las 230 barreras se clasificaron acorde al modelo de Tanahashi: 25 corresponden a la dimensión disponibilidad, 67 a accesibilidad, 87 a aceptabilidad y 51 a contacto. La mayor proporción de barreras correspondió a la dimensión de aceptabilidad y de accesibilidad. Los elementos facilitadores identificados tienen relación con factores personales, relación entre prestadores y usuarios, apoyo social, información sobre la enfermedad y adaptación de los servicios al paciente. CONCLUSIONES: La identificación de barreras y facilitadores se realiza mayoritariamente en personas que han contactado los sistemas sanitarios y en todas las etapas del proceso de acceso a la atención de salud. Se identificaron pocos estudios orientados a quienes no contactan los servicios. Las barreras y facilitadores identificados están socialmente determinados, y la mayoría son expresión de inequidades sociales que existen en los países y requieren una acción conjunta con otros sectores distintos de salud para ser reducidas o eliminadas.
