Preeclampsia Increases the Incidence of Postpartum Cerebrovascular Disease in Korean Population

BACKGROUND: Multiple studies have been reported regarding preeclampsia as a possible risk factor of cerebrovascular disease (CVD). However, the correlation of preeclampsia and CVD, whether it is a cause-effect relationship or they are sharing common predisposing condition, is not well understood. Therefore, the aim of this study was to investigate the association between the preeclampsia during pregnancy and development of postpartum CVD. METHODS: A total of 1,384,550 Korean women who had a delivery between January 1, 2010 and December 31, 2012, were enrolled. Women with the risk of CVD within 1 year prior to pregnancy were excluded based on the Charlson comorbidity index. Primary endpoint was the event of CVD within a year from delivery. After exclusion, 1,075,061 women were analyzed. RESULTS: During the follow-up of 1 year postpartum, there were 25,577 preeclampsia out of 1,072,041 women without postpartum CVD (2.39%), and 121 of 3,020 women with postpartum CVD had preeclampsia before delivery (4.01%). In multivariate logistic regression analysis, women who had preeclampsia during pregnancy showed a higher risk for postpartum CVD (odds ratio, 1.64; 95% confidence interval, 1.37–1.98). CONCLUSION: The incidence of CVD after delivery was higher in women who had preeclampsia during pregnancy.

Utilization of Western and Traditional Korean Medicine for Children and Adolescents with Mental Disorders: a Nationwide Population-based Study from 2010 to 2012

When in need of medical treatment, Korean citizens have a choice of practitioners of western medicine (WM) or Traditional Korean Medicine (TKM). However, the two branches frequently conflict with one another, particularly with regard to mental disorders. This study was designed to compare the utilization of WM and TKM, focusing on child/adolescent patients with mental disorders. We analyzed F-code (Mental and behavioral disorders) claims from the Korean Health Insurance Review and Assessment Service, including data from 0-18-year-old patients from 2010 to 2012. Slightly more men than women utilized WM, while TKM use was almost evenly balanced. WM claims increased with advancing age, whereas utilization of TKM was common for the 0-6 age group. In WM and TKM, the total number of claims relying on the National Health Insurance Service (NHIS) was 331,154 (92.78%) and 73,282 (97.85%), respectively, and the number of claims relying on medical aid was 25,753 (7.22%) and 1,610 (2.15%), respectively. The most frequent F-coded claim in WM was F90 (Hyperkinetic disorders), with 64,088 claims (17.96%), and that in TKM was F45 (Somatoform disorders), with 28,852 claims (38.52%). The prevalence of a single disorder without comorbidities was 168,764 (47.29%) in WM and 52,615 (70.25%) in TKM. From these data, we conclude that WM takes prevalence over TKM in cases of attention deficit/hyperactivity disorder (ADHD), as well as in psychological problems such as depression and anxiety. On the other hand, patients utilizing TKM more commonly present with physical health problems including somatoform problems, sleep, and eating disorders.

Administrative and clinical denials by a large dental insurance provider

The objective of this study was to assess the prevalence and the type of claim denials (administrative, clinical or both) made by a large dental insurance plan. This was a cross-sectional, observational study, which retrospectively collected data from the claims and denial reports of a dental insurance company. The sample consisted of the payment claims submitted by network dentists, based on their procedure reports, reviewed in the third trimester of 2012. The denials were classified and grouped into ‘administrative’, ‘clinical’ or ‘both’. The data were tabulated and submitted to uni- and bivariate analyses. The confidence intervals were 95% and the level of significance was set at 5%. The overall frequency of denials was 8.2% of the total number of procedures performed. The frequency of administrative denials was 72.88%, whereas that of technical denials was 25.95% and that of both, 1.17% (p < 0.05). It was concluded that the overall prevalence of denials in the studied sample was low. Administrative denials were the most prevalent. This type of denial could be reduced if all dental insurance providers had unified clinical and administrative protocols, and if dentists submitted all of the required documentation in accordance with these protocols.

The Economic Burden of Cancers Attributable to Metabolic Syndrome in Korea / 예방의학회지

OBJECTIVES: Metabolic syndrome is an important etiologic factor in the development of certain types of cancers. The economic cost of the treatment of cancer has been steadily increasing. We therefore estimated the economic burden of cancers attributable to metabolic syndrome in Korea. METHODS: We reviewed metabolic syndrome-related cancers and relative risk and then calculated population attributable fractions. We analyzed insurance claims data for metabolic syndrome-related cancers in 2012 in order to estimate the direct costs associated with these cancers, including hospitalization, outpatient visits, transportation costs, and caregivers' costs as well as indirect costs such as loss of productivity due to cancer treatment and premature death. RESULTS: In 2012, 18 070 patients in Korea had cancers attributable to metabolic syndrome. The economic burden was USD 199.8 million and the direct and indirect costs were USD 124.5 million and USD 75.3 million, respectively. CONCLUSIONS: We estimated the economic burden of cancers attributable to metabolic syndrome in Korea and the efforts are necessary to reduce this burden.

Associations Between the Continuity of Ambulatory Care of Adult Diabetes Patients in Korea and the Incidence of Macrovascular Complications / 예방의학회지

OBJECTIVES: The goal of this study was to identify association between the continuity of ambulatory care of diabetes patients in South Korea (hereafter Korea) and the incidence of macrovascular complications of diabetes, using claims data compiled by the National Health Insurance Services of Korea. METHODS: This study was conducted retrospectively. The subjects of the study were 43 002 patients diagnosed with diabetes in 2007, who were over 30 years of age, and had insurance claim data from 2008. The macrovascular complications of diabetes mellitus were limited to ischemic heart disease and ischemic stroke. We compared the characteristics of the patients in whom macrovascular complications occurred from 2009 to 2012 to the characteristics of the patients who had no such complications. Multiple logistic regression was used to assess the effects of continuity of ambulatory care on diabetic macrovascular complications. The continuity of ambulatory diabetes care was estimated by metrics such as the medication possession ratio, the quarterly continuity of care and the number of clinics that were visited. RESULTS: Patients with macrovascular complications showed statistically significant differences regarding sex, age, comorbidities, hypertension, dyslipidemia and continuity of ambulatory diabetes care. Visiting a lower number of clinics reduced the odds ratio for macrovascular complications of diabetes. A medication possession ratio below 80% was associated with an increased odds ratio for macrovascular complications, but this result was of borderline statistical significance. CONCLUSIONS: Diabetes care by regular health care providers was found to be associated with a lower occurrence of diabetic macrovascular complications. This result has policy implications for the Korean health care system, in which the delivery system does not work properly.

Treatment Gap in the National Health-screening Program in Korea: Claim-based Follow-up of Statin Use for Sustained Hypercholesterolemia

Participation in a screening program by itself may not improve clinical outcomes. Treatment gaps in the program may limit its full benefit. We evaluated statin prescription rates for subjects with sustained hypercholesterolemia to assess the treatment gaps in the National Health Screening Program (NHSP) in Korea. A retrospective, random cohort was established among National Health Insurance Corporation (NHIC) members. Finally, we examined 465,499 individuals who attended the NHSP from 2003 to 2010 without any history of dyslipidemia, statin prescription, or hospitalization for cardiovascular events until the end of 2002. The subsequent statin prescription rates were identified from the NHIC medical service claim database from 2003 to 2011. Descriptive data and odds ratio from multivariate logistic analyses on statin prescription rates and the corresponding correlations were evaluated. The NHSP detected 114,085 (24.5%) cases of newly diagnosed hypercholesterolemia. However, only 8.6% of these received statin prescription within 6 months of diagnosis. For cases of sustained hypercholesterolemia determined in the next screening visit by the NHSP, the statin prescription rate increased, but only to 12.2%. Statin prescriptions were more common among females, older individuals, and hypertension or diabetes patients. Furthermore, the statin prescription rates had increased over the study period. The NHSP exhibited low statin prescription rate which has been improving. For the NHSP to be effective, it would be worthwhile to decrease the gap between the diagnosis of hypercholesterolemia and the following treatment.

Feasibility of road traffic injury surveillance integrating police and health insurance data sets in the Dominican Republic / Factibilidad de la vigilancia de las lesiones por accidentes de tránsito mediante la integración de los conjuntos de datos de la policía y del seguro nacional de salud en la República Dominicana

OBJECTIVE: To assess the feasibility of semiautomated linking of road traffic injury (RTI) cases in different data sets in low- and middle-income countries. METHODS: The study population consisted of RTI cases in the Dominican Republic in 2010 and were identified in police and health insurance data sets. After duplicates were removed and fatality reporting was corrected by using forensic data, police and health insurance RTI records were linked if they had the same province, collision date, and gender of RTI cases and similar age within five years. A multinomial logistic regression model assessed the likelihood of being in only one of the data sets. RESULTS: One of five records was a duplicate, including 21.1% of 6 396 police and 16.2% of 6 178 insurance records. Health insurance data recorded 43 of 417 deaths as only injured. Capture - recapture estimated that both data sets recorded one of five RTI cases. Characteristics associated with increased likelihood (P < 0.05) of being only in the police data set were female gender [adjusted odds ratio (OR) = 2.5], age ≥ 16 years (OR = 1.7), collision in the regions of Cibao Northeast (OR = 4.1) and Valdesia (OR = 6.4), day of occurrence from Tuesday to Saturday (ORs from 1.5 to 2.9), month of occurrence from October to December (ORs from 1.6 to 4.5), and occupant of four-wheeled vehicles (OR = 5.4) or trucks (OR = 5.3). CONCLUSIONS: Consistent semiautomated linking procedures were feasible to ascertain the RTI burden in the Dominican Republic and could be improved by standardized coding of police and health insurance RTI reporting.

OBJETIVO: Evaluar la factibilidad de la vinculación semiautomática de los registros de casos de lesiones por accidentes de tránsito (LAT) de diferentes conjuntos de datos en países de ingresos bajos y medianos. MÉTODOS: La población de estudio la constituían los casos de LAT ocurridos en la República Dominicana en el 2010 y registrados en los conjuntos de datos de la policía y del seguro nacional de salud. Después de eliminar los casos duplicados y corregir la notificación de defunciones a partir de los datos forenses, se vincularon los registros de LAT de la policía y el seguro de enfermedad si los casos correspondían a la misma provincia, fecha de colisión y sexo, y la edad era similar con una diferencia no superior a cinco años. Se evaluó la probabilidad de aparecer únicamente en uno de los conjuntos de datos mediante un modelo de regresión logística polinómica. RESULTADOS: Uno de cada cinco registros estaba duplicado (21,1% de los 6 396 registros de la policía y 16,2% de los 6 178 registros del seguro). En el conjunto de datos del seguro nacional de salud se registraron 43 de las 417 defunciones como únicamente lesionados. Mediante el método de captura-recaptura se calculó que en ambos conjuntos de datos se registraban uno de cada cinco casos de LAT. Las características asociadas con una mayor probabilidad (P < 0,05) de aparecer únicamente en el conjunto de datos de la policía fueron el sexo femenino (razón de posibilidades ajustada [OR] = 2,5), la edad ≥ 16 años (OR = 1,7), la colisión en las regiones del nordeste de Cibao (OR = 4,1) y Valdesia (OR = 6,4), el día del accidente de martes a sábado (OR de 1,5 a 2,9), el mes del accidente de octubre a diciembre (OR de 1,6 a 4,5) y los ocupantes de vehículos de cuatro ruedas (OR = 5,4) o camiones (OR = 5,3). CONCLUSIONES: Los procedimientos sistemáticos de vinculación semiautomatizada se mostraron factibles para evaluar la carga de LAT en la República Dominicana, y se podrían mejorar mediante la codificación estandarizada de las notificaciones de LAT de la policía y del seguro nacional de salud.

Evidence of adverse selection in Iranian supplementary health insurance market

Existence or non-existence of adverse selection in insurance market is one of the important cases that have always been considered by insurers. Adverse selection is one of the consequences of asymmetric information. Theory of adverse selection states that high-risk individuals demand the insurance service more than low risk individuals do. The presence of adverse selection in Iran's supplementary health insurance market is tested in this paper. The study group consists of 420 practitioner individuals aged 20 to 59. We estimate two logistic regression models in order to determine the effect of individual's characteristics on decision to purchase health insurance coverage and loss occurrence. Using the correlation between claim occurrence and decision to purchase health insurance, the adverse selection problem in Iranian supplementary health insurance market is examined. Individuals with higher level of education and income level purchase less supplementary health insurance and make fewer claims than others make and there is positive correlation between claim occurrence and decision to purchase supplementary health insurance. Our findings prove the evidence of the presence of adverse selection in Iranian supplementary health insurance market

A road traffic injury surveillance system using combined data sources in Peru / Sistema de vigilancia de traumatismos por accidentes de tránsito con fuentes de datos combinadas en el Perú

A national hospital-based nonfatal road traffic injury surveillance system was established at sentinel units across Peru in 2007 under the leadership of the Ministry of Health. Surveillance data are drawn from three different sources (hospital records, police reports, and vehicle insurance reports) and include nonfatal road traffic injuries initially attended at emergency rooms. A single data collection form is used to record information about the injured, event characteristics related to the driver of the vehicle(s), and the vehicle(s). Data are analyzed periodically and disseminated to all surveillance system participants. Results indicated young adult males (15-29 years old) were most affected by nonfatal road traffic injuries and were most often the drivers of the vehicles involved in the collision. Four-wheeled vehicle occupants comprised one-half of cases in most regions of the country, and pedestrians injured in the event accounted for almost another half. The system established in Peru could serve as a model for the use of multiple data sources in national nonfatal road traffic injury surveillance. Based on this study, the challenges of this type of system include sustaining and increasing participation among sentinel units nationwide and identifying appropriate prevention interventions at the local level based on the resulting data.

Con el liderazgo del Ministerio de Salud, en el 2007 se estableció un sistema hospitalario nacional de vigilancia de traumatismos no mortales por accidentes de tránsito en unidades centinela de todo el Perú. Los datos de vigilancia se extraen de tres fuentes diferentes (registros hospitalarios, informes policiales e informes del seguro del vehículo) e incluyen los traumatismos no mortales por accidentes de tránsito atendidos inicialmente en las salas de urgencia. Se usa un único formulario de recopilación de datos para registrar la información sobre los heridos, las características del hecho relacionadas con el conductor o los conductores de los vehículos y del vehículo o los vehículos involucrados. Los datos se analizan periódicamente y se comunican a todos los participantes del sistema de vigilancia. Los resultados indicaron que los hombres adultos jóvenes (de 15 a 29 años) fueron los más afectados por traumatismos no mortales por accidentes de tránsito y con mayor frecuencia eran los conductores de los vehículos que participaron en la colisión. Los ocupantes de vehículos de cuatro ruedas representaron la mitad de los casos en la mayoría de las zonas del país y los peatones lesionados en el hecho representaron prácticamente la otra mitad. El sistema establecido en el Perú podría servir de modelo del uso de múltiples fuentes de datos para la vigilancia a nivel nacional de traumatismos no mortales por accidentes de tránsito. Según los resultados de este estudio, los retos de un sistema de este tipo consisten en mantener y aumentar la participación de las unidades de vigilancia de todo el país y determinar las intervenciones de prevención adecuadas en el nivel local según los datos obtenidos.

Doenças do trabalho e benefícios previdenciários relacionados à saúde, Bahia, 2000 / Work-related diseases and health-related compensation claims, Northeastern Brazil, 2000 / Enfermedades del trabajo y beneficios de la previsión relacionados a la salud, Bahia (Brasil), 2000

OBJETIVO: Estimar a contribuição das doenças relacionadas ao trabalho nos afastamentos por problemas de saúde em geral e ocupacionais. MÉTODOS: Foram analisados dados sociodemográficos, ocupacionais e de saúde referentes a 29.658 registros dos benefícios por incapacidade temporária concedidos por agravos à saúde pelo Instituto Nacional do Seguro Social, no Estado da Bahia, em 2000. Foram considerados casos todos os diagnósticos clínicos constantes da CID-10, com exceção das causas externas e fatores que influenciam o contato com os serviços de saúde. A vinculação do diagnóstico com a ocupação baseou-se no código CID-10 e se a espécie do benefício era "acidentária". RESULTADOS: Dentre os benefícios, 3,1 por cento foram concedidos para doenças do trabalho: 70 por cento eram doenças do sistema osteomuscular e do tecido conjuntivo e 14,5 por cento do sistema nervoso. No geral, benefícios concedidos numa freqüência maior que o dobro da esperada foram: para tenossinovites na indústria da transformação (Razão de Proporção-RP=2,70), síndrome do túnel do carpo na intermediação financeira (RP=2,43) e transtornos do disco lombar no ramo de transporte, correio e telecomunicações (RP=2,17). Entretanto, não foi estabelecido nexo causal para estas doenças, nesses ramos de atividade, em percentual significativo de benefícios. CONCLUSÕES: Os resultados sugerem a existência de possíveis fatores de risco ocupacionais para enfermidades nesses ramos de atividade, como também o sub-registro da vinculação das patologias com o trabalho, camuflando a responsabilidade das empresas e a perspectiva de prevenção pela reorganização do trabalho.

OBJECTIVE: To estimate the contribution of work-related diseases to sick leaves due to general and occupational health problems. METHODS: Sociodemographic, occupational and health data from 29,658 records of temporary disability benefits, granted on account of health problems by the Instituto Nacional do Seguro Social (National Institute of Social Security) in the state of Bahia (Northeastern Brazil), were analyzed. All constant ICD-10 clinical diagnoses were taken into consideration, except for those referring to external causes and factors that influence contact with health services. The link between diagnosis and occupation was based on the ICD-10 code and whether the type of compensation was due to a "work-related accident/disease" or not. RESULTS: From all the benefits, 3.1 percent were granted due to work-related diseases: 70 percent were musculoskeletal system and connective tissue diseases, while 14.5 percent were related to the nervous system. In general, benefits granted at more than two times the expected frequency were as follows: tenosynovitis in the manufacturing sector (Proportion Ratio-PR=2.70), carpal tunnel syndrome in the financial intermediation sector (PR=2.43), and lumbar disc degeneration in the transportation, postal service and telecommunications sectors (PR=2.17). However, no causal connection could be established for these diseases, in these activity sectors, in a significant percentage of benefits. CONCLUSIONS: Results suggest the existence of possible occupational risk factors for diseases in these fields of activity, as well as the underreporting of the link between diseases and work, thus disguising the responsibility of companies and the perspective of prevention through work reorganization.

OBJETIVO: Estimar la contribución de las enfermedades relacionadas al trabajo en las licencias por problemas de salud en general y ocupacionales. MÉTODOS: Fueron analizados datos sociodemográficos, ocupacionales y de salud referentes a 29.658 registros de los beneficios por incapacidad temporal concedidos por agravamientos a la salud por el Instituto Nacional do Seguro Social, en el estado de Bahia (Nordeste de Brasil), en 2000. Fueron considerados como casos todos los diagnósticos clínicos constantes de CID-10, con excepción de las causas externas y factores que influencian el contacto con los servicios de salud. La vinculación del diagnóstico con la ocupación se baso en el código CID-10 y si la especie de beneficio era "accidentaria". RESULTADOS: De los beneficios, 3,1 por ciento fueron concedidos para enfermedades de trabajo: 70 por ciento eran enfermedades del sistema osteomuscular y del tejido conjuntivo y 14,5 por ciento del sistema nervioso.

Sin embargo, no fue establecido nexo causal para estas enfermedades, en estos ramos de actividad, en porcentual significativo de beneficios. CONCLUSÕES: Los resultados sugieren la existencia de posibles factores de riesgo ocupacionales para enfermedades en estos ramos de actividad, como también el sub-registro de la vinculación de las patologías con el trabajo, camuflando la responsabilidad de las empresas y la perspectiva de premención por la reorganización del trabajo.

Helping members of a community-based health insurance scheme access quality inpatient care through development of a preferred provider system in rural Gujarat.

We describe and analyse the experience of piloting a preferred provider system (PPS) for rural members of Vimo SEWA, a fixed-indemnity, community-based health insurance (CBHI) scheme run by the Self-Employed Women's Association (SEWA). The objectives of the PPS were (i) to facilitate access to hospitalization by providing financial benefits at the time of service utilization; (ii) to shift the burden of compiling a claim away from members and towards Vimo SEWA staff; and (iii) to direct members to inpatient facilities of acceptable quality. The PPS was launched between August and October 2004, in 8 subdistricts covering 15,000 insured. The impact of the scheme was analysed using data from a household survey of claimants and qualitative data from in-depth interviews and focus group discussions. The PPS appears to have been successful in terms of two of the three primary objectives--it has transferred much of the burden of compiling a health Insurance claim onto Vimo SEWA staff, and it has directed members to inpatient facilities with acceptable levels of technical quality (defined in terms of structural Indicators). However, even under the PPS, user fees pose a financial barrier, as the insured have to mobilize funds to cover the costs of medicines, supplies, registration fee, etc. before receipt of cash payment from Vimo SEWA. Other barriers to the success of the PPS were the geographic Inaccessibility of some of the selected hospitals, lack of awareness about the PPS among members and a variety of administrative problems. This pilot project provides useful lessons relating to strategic purchasing by CBHI schemes and, more broadly, managed care in India. In particular, the pragmatic approach taken to assessing hospitals and identifying preferred providers is likely to be useful elsewhere.

Diseño del proceso de estudio de cuentas de cobro por S.O.A.T. en Seguros del Estado S.A., 1998 / Study process design on billing to S.O.A.T. (Traffic Accidents Mandatory Insurance) in Seguros del Estado S.A. 1998

Seguros del Estado S.A. maneja en la actualidad el 30 por ciento del mercado Seguro Obligatorio de Accidente de Tránsito (SOAT), volumen que ha causado en la empresa un atraso en los pagos a los diferentes acreedores, esto hace que surja la necesidad de revisar el proceso y elaborar el rediseño del mismo para optimizarlo. Para su desarrollo se siguieron los siguientes pasos: revisión del marco teórico, análisis de la organización, levantamiento del proceso actual, rediseño del proceso, presentación de la propuesta a la gerencia y elaboración del informe final. El análisis del proceso detectó múltiples falencias tales como, falta de delegación, duplicación de actividades, manual de funciones inadecuado, subutilización del talento humano, etc. Se incluyó que se debe rediseñar el proceso y elaborar un nuevo manual de funciones.
