Reusing a prepaid health plan's fecal immunochemical tests for microbiome associations with colorectal adenoma.

An altered colonic microbiota probably increases colorectal adenoma (CRA) and cancer (CRC) risk, but large, unbiased fecal collections are needed to examine the relationship of gut microbiota diversity and composition to colorectal carcinogenesis. This study assessed whether fecal immunochemical tests (FITs) from CRA/CRC screening may fulfill this requirement. Using FIT, self-collected by members of Kaiser Permanente Hawaii (KPH), as well as interspersed quality control (QC) specimens, DNA was extracted and amplified to generate 16S rRNA microbiome profiles rarified at 10,000 reads. CRA/CRC were diagnosed by colonoscopy and histopathology. Covariates were from electronic KPH records. Of 921 participants' FIT devices, 538 (58%) yielded at least 10,000 rRNA reads and 1016 species-level variants mapped to 46 genera. Of the 538 evaluable participants, 63 (11.7%) were FIT-negative per protocol, and they were considered negative for CRA/CRC. Of the 475 FIT + participants, colonoscopy and pathologic review revealed that 8 (1.7%) had CRC, 71 (14.9%) had high-risk CRA, 107 (22.5%) had low-risk CRA, and 289 (60.8%) did not have CRA/CRC. Men were 2.27-fold [95% confidence interval (CI) 1.32-3.91] more likely than women to be FIT+ . Men also had 1.96-fold (CI 1.24-3.07) higher odds of low-risk CRA, with similar trends for high-risk CRA and CRC. CRA/CRC were not associated with overweight, obesity, diabetes, or antibiotic prescriptions in this study. QC analysis across 24 batches of FIT devices revealed QC outliers in four batches. With or without exclusion of the four QC-outlier batches, as well as lenient (1000-read) rarefaction, CRA/CRC had no consistent, statistically significant associations with fecal microbiome alpha diversity, beta diversity or genera relative abundance. CRA/CRC had expected associations with male sex but not with microbiome metrics. Fecal microbiome profiling using DNA extracted from at-home collected, re-used FIT devices is feasible, albeit with substantial challenges. Using FITs for prospective microbiome studies of CRA/CRC risk should consider the impact of the current findings on statistical power and requisite sample sizes.

Judicialization of health arising from prepaid insurance plans and health law: an integrative review.

OBJECTIVE: To analyze publications regarding judicial demands related to the violation of the rights of the client who uses private health insurance in Brazil. METHOD: Integrative review, from September to October 2017, of national character, with complete texts online, in Portuguese and English, published between 2012 and 2017 in the Virtual Health Library portal, excluding studies that were duplicated or with indiscriminate methodology. RESULTS: The judicial demands were for: medication (32%); ward hospitalization (11%); surgical procedures (9%); orthosis, prothesis and special materials (9%); others (9%); and diagnostic procedures, outpatient service, hospitalization in Intensive Care Units, food formulas and disposable diapers (30%). CONCLUSION: The prevalence of legal disputes arising from the failure in providing health service by private health insurances was observed, which makes it easier for the administrators to identify the sought health products and services in order to reorganize the administrative sphere and provide quality care.

Past, present, and future of global health financing: a review of development assistance, government, out-of-pocket, and other private spending on health for 195 countries, 1995-2050.

BACKGROUND: Comprehensive and comparable estimates of health spending in each country are a key input for health policy and planning, and are necessary to support the achievement of national and international health goals. Previous studies have tracked past and projected future health spending until 2040 and shown that, with economic development, countries tend to spend more on health per capita, with a decreasing share of spending from development assistance and out-of-pocket sources. We aimed to characterise the past, present, and predicted future of global health spending, with an emphasis on equity in spending across countries. METHODS: We estimated domestic health spending for 195 countries and territories from 1995 to 2016, split into three categories-government, out-of-pocket, and prepaid private health spending-and estimated development assistance for health (DAH) from 1990 to 2018. We estimated future scenarios of health spending using an ensemble of linear mixed-effects models with time series specifications to project domestic health spending from 2017 through 2050 and DAH from 2019 through 2050. Data were extracted from a broad set of sources tracking health spending and revenue, and were standardised and converted to inflation-adjusted 2018 US dollars. Incomplete or low-quality data were modelled and uncertainty was estimated, leading to a complete data series of total, government, prepaid private, and out-of-pocket health spending, and DAH. Estimates are reported in 2018 US dollars, 2018 purchasing-power parity-adjusted dollars, and as a percentage of gross domestic product. We used demographic decomposition methods to assess a set of factors associated with changes in government health spending between 1995 and 2016 and to examine evidence to support the theory of the health financing transition. We projected two alternative future scenarios based on higher government health spending to assess the potential ability of governments to generate more resources for health. FINDINGS: Between 1995 and 2016, health spending grew at a rate of 4·00% (95% uncertainty interval 3·89-4·12) annually, although it grew slower in per capita terms (2·72% [2·61-2·84]) and increased by less than $1 per capita over this period in 22 of 195 countries. The highest annual growth rates in per capita health spending were observed in upper-middle-income countries (5·55% [5·18-5·95]), mainly due to growth in government health spending, and in lower-middle-income countries (3·71% [3·10-4·34]), mainly from DAH. Health spending globally reached $8·0 trillion (7·8-8·1) in 2016 (comprising 8·6% [8·4-8·7] of the global economy and $10·3 trillion [10·1-10·6] in purchasing-power parity-adjusted dollars), with a per capita spending of US$5252 (5184-5319) in high-income countries, $491 (461-524) in upper-middle-income countries, $81 (74-89) in lower-middle-income countries, and $40 (38-43) in low-income countries. In 2016, 0·4% (0·3-0·4) of health spending globally was in low-income countries, despite these countries comprising 10·0% of the global population. In 2018, the largest proportion of DAH targeted HIV/AIDS ($9·5 billion, 24·3% of total DAH), although spending on other infectious diseases (excluding tuberculosis and malaria) grew fastest from 2010 to 2018 (6·27% per year). The leading sources of DAH were the USA and private philanthropy (excluding corporate donations and the Bill & Melinda Gates Foundation). For the first time, we included estimates of China's contribution to DAH ($644·7 million in 2018). Globally, health spending is projected to increase to $15·0 trillion (14·0-16·0) by 2050 (reaching 9·4% [7·6-11·3] of the global economy and $21·3 trillion [19·8-23·1] in purchasing-power parity-adjusted dollars), but at a lower growth rate of 1·84% (1·68-2·02) annually, and with continuing disparities in spending between countries. In 2050, we estimate that 0·6% (0·6-0·7) of health spending will occur in currently low-income countries, despite these countries comprising an estimated 15·7% of the global population by 2050. The ratio between per capita health spending in high-income and low-income countries was 130·2 (122·9-136·9) in 2016 and is projected to remain at similar levels in 2050 (125·9 [113·7-138·1]). The decomposition analysis identified governments' increased prioritisation of the health sector and economic development as the strongest factors associated with increases in government health spending globally. Future government health spending scenarios suggest that, with greater prioritisation of the health sector and increased government spending, health spending per capita could more than double, with greater impacts in countries that currently have the lowest levels of government health spending. INTERPRETATION: Financing for global health has increased steadily over the past two decades and is projected to continue increasing in the future, although at a slower pace of growth and with persistent disparities in per-capita health spending between countries. Out-of-pocket spending is projected to remain substantial outside of high-income countries. Many low-income countries are expected to remain dependent on development assistance, although with greater government spending, larger investments in health are feasible. In the absence of sustained new investments in health, increasing efficiency in health spending is essential to meet global health targets. FUNDING: Bill & Melinda Gates Foundation.

Hospitalization in older adults: association with multimorbidity, primary health care and private health plan.

OBJECTIVE: Evaluate the association of multimorbidity, primary health care model and possession of a private health plan with hospitalization. METHODS: A population-based cross-sectional study with 1,593 elderly individuals (60 years old or older) living in the urban area of the city of Bagé, State of Rio Grande do Sul, Brazil. The outcome was hospitalization in the year preceding the interview. The multimorbidity was evaluated through two cut-off points (≥ 2 and ≥ 3). The primary health care model was defined by residence in areas covered by traditional care or by Family Health Strategy. The older adults mentioned the possession of a private health plan. We performed a gross and adjusted analysis by Poisson regression using a hierarchical model. The adjustment included demographic, socioeconomic, functional capacity disability and health services variables. RESULTS: The occurrence of overall and non-surgical hospitalization was 17.7% (95%CI 15.8-19.6) and 10.6% (95%CI 9.1-12.1), respectively. Older adults with multimorbidity were admitted to hospitals more often when to older adults without multimorbidity, regardless of the exhibition' form of operation. Having a private health plan increased the hospitalization by 1.71 (95%CI 1.09-2.69) times among residents in the areas of the Family Health Strategy when compared to elderly residents in traditional areas without a private health plan. CONCLUSIONS: The multimorbidity increased the occurrence of hospitalizations, especially non-surgical ones. Hospitalization was more frequent in older adults with private health plan and those living in Family Health Strategy areas, regardless of the presence of multiple diseases. OBJETIVO: Avaliar a associação da multimorbidade, modelo de atenção básica e posse de plano de saúde com hospitalização. MÉTODOS: Estudo transversal de base populacional com 1.593 idosos (60 anos ou mais) residentes na zona urbana do município de Bagé, Rio Grande do Sul. O desfecho foi a hospitalização no ano anterior à entrevista. A multimorbidade foi avaliada por meio de dois pontos de corte (≥ 2 e ≥ 3). O modelo de atenção básica foi definido pela residência em áreas cobertas pela atenção tradicional ou da Estratégia Saúde da Família. A posse de plano de saúde foi referida pelos idosos. Realizou-se análise bruta e ajustada por regressão de Poisson utilizando modelo hierarquizado. O ajuste incluiu variáveis demográficas, socioeconômicas, capacidades funcionais e de serviços de saúde. RESULTADOS: A ocorrência de hospitalização geral e não cirúrgica foi de 17,7% (IC95% 15,8-19,6) e 10,6% (IC95% 9,1-12,1), respectivamente. Idosos com multimorbidade hospitalizaram mais em comparação com os idosos sem multimorbidade, independentemente da forma de operacionalização da exposição. O plano de saúde aumentou em 1,71 (IC95% 1,09-2,69) vezes a internação hospitalar entre residentes nas áreas da Estratégia Saúde da Família em comparação aos idosos residentes nas áreas tradicionais sem plano de saúde. CONCLUSÕES: A multimorbidade aumentou a ocorrência de hospitalizações, principalmente aquelas não cirúrgicas. Idosos com plano de saúde e residentes em áreas de Estratégia Saúde da Família internaram mais, independentemente da presença de múltiplas doenças.

[Health behaviors and preventive tests in adults with and without health insurance in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil, 2003-2010]. / Comportamentos em saúde e exames preventivos entre adultos filiados ou não a planos de saúde na Região Metropolitana de Belo Horizonte, Minas Gerais, Brasil, 2003-2010.

This study analyzed indicators for health behaviors and use of preventive services in two probabilistic samples of adults, one in 2003 (n = 13,757) and the other in 2010 (n = 12,983), with and without private health insurance in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil. After adjusting for demographic variables, temporal variation, and source of care, there was a reduction in smoking prevalence, similar between individuals with and without private health insurance, from 2003 to 2010. During this same period the prevalence of excessive alcohol intake and sedentary lifestyle increased in both groups; with the same magnitude, there was a decrease in the prevalence of leisure-time physical activity. No changes were observed in the prevalence of blood pressure measurement, but the prevalence of cholesterol testing, mammogram, and Pap smear increased more sharply in individuals without health insurance.

From health plan companies to international insurance companies: changes in the accumulation regime and repercussions on the healthcare system in Brazil.

The concentration and internationalization of health plan companies in Brazil gave them a clearly financial face. Based on the need to understand the health care industry's capital accumulation patterns, the current study examines health plan companies' expansion strategies through the classification of their supply and demand characteristics by recent historical periods and an analysis of recent shareholding trends in one of the leading corporations in the Brazilian health care industry. The 1960s to 2000s witnessed changes in the scale of demands for health plans and adherence by companies to long-term accumulation strategies. Beginning in the early 21st century, changes in the shareholding structures of the largest Brazilian company, consistent with the financialization of its accumulation regime, resulted in the rapid multiplication of its capital. Deepening segmentation of the health care system in a context marked by the downturn in the national economy challenges the preservation of public subsidies for private health plans. Resumo: A concentração e internacionalização de empresas de planos de saúde no Brasil conferiram-lhes feição financeira. Considerando a necessidade de compreender os padrões de acumulação desse setor, o trabalho examina estratégias de expansão das empresas de planos de saúde por meio da periodização de atributos da oferta e demanda e exame da trajetória patrimonial recente de um dos grandes grupos do setor. Entre os anos 1960 e 2000, ocorreram alterações na escala das demandas por planos de saúde e adesão das empresas a estratégias de acumulação de longo prazo. A partir do século XXI, as alterações nas estruturas societárias da maior empresa brasileira, compatíveis com o regime de acumulação financeirizada, resultaram na multiplicação de seu capital em um curto intervalo de tempo. O aprofundamento da segmentação do sistema de saúde, em um contexto marcado pela desaceleração da economia, questiona a preservação dos subsídios públicos para os planos privados.

[Variation in hospital performance according to payment sources in the states of São Paulo and do Rio Grande do Sul, Brazil]. / Variação do desempenho hospitalar segundo fontes de pagamento nos estados de São Paulo e Rio Grande do Sul, Brasil.

In Brazil, the combined presence of public and private interests in financing and provision of healthcare services stands out clearly in hospital care. Financing arrangements adopted by hospitals (the public Brazilian Unified National Health System - SUS and/or health plans and/or out-of-pocket payment) can affect quality of care. Studies have analyzed the hospital standardized mortality ratio (HSMR) in relation to quality improvements. The objective was to analyze HSMR according to source of payment for the hospitalization and the hospital's financing arrangement. The study analyzed secondary data and causes that accounted for 80% of hospital deaths. HSMR was calculated for each hospital and payment source. Hospitals with worse-than-expected performance (HSMR > 1) were mostly large public hospitals. HSMR was higher in the SUS, including between admissions in the hospital. Despite the study's limitations, the findings point to inequalities in results of care. Efforts are needed to improve the quality of hospital services, regardless of the payment sources.

[Hospital readmission rate and associated factors among health services enrollees in Colombia]. / Frecuencia de reingresos hospitalarios y factores asociados en afiliados a una administradora de servicios de salud en Colombia.

Hospital readmissions are common and expensive, and there is little information on the problem in Colombia. The objective was to determine the frequency of 30-day all-cause hospital readmissions and associated factors. This was a retrospective analytical cohort study of 64,969 hospitalizations from January 2008 to January 2009 in 47 Colombian cities. 6,573 hospital readmissions, prevalence: 10.1% (men 10.9%, women 9.5%), 44.7% > 65 years of age. Hospital readmissions was associated with higher mortality (5.8% vs. 1.8%). There was an increase in the Hospital readmissions rate in patients with diseases of the circulatory system. Hospital readmissions was more likely in hematological diseases and neoplasms. Mean length of stay during the first readmission was 7 days in patients that were readmitted and 4.5 in those without readmission. Greater total cost of hospital readmissions (USA 21,998,275): 15.8% of the total cost of hospitalizations. Higher prevalence rates in referred patients (18.8%) and patients from the outpatient clinic (13.7%). Hospital readmissions is common and is associated with longer length of hospital stay and higher mortality and cost. Increased risk of hospital readmissions in men > 65 years, patients referred from other institutions, and in hematological diseases and neoplasms.

[The role of the Constitutional Court on the analysis of contracts of prepaid medicine programs]. / El papel de la Corte Constitucional en el análisis de los contratos de medicina prepagada.

Since 1991, when the current Colombian Constitution came into force and the Constitutional Court was appointed as its guardian and protector, constitutional values have permeated all subjects and areas of law, even those that were previously considered as private matters. Prepaid medicine contracts are a good example of this phenomenon, since the Colombian Constitutional Court has limited individual freedom of contract to private parties -prepaid medical companies- for the benefit of final users of this service through "acción de tutela", in order to protect the right to healthcare and to prevent some behaviors that violate the principle of good faith. The Court has demanded private companies to assess the health condition of patients and has prohibited pre-existent and exclusion clauses that diminish the responsibilities of said companies. Nevertheless, there is a gap in the law regarding the duties of good faith that concern the user, which will be addressed in this paper.

2014: Rural Medicare Advantage Enrollment Update.

Key Data Findings. (1) Reclassification of rural and urban county designations (due to the switch from 2000 census data to 2010 census data) resulted in a 10 percent decline in the number of Medicare eligible Americans living in rural counties in 2014 (from roughly 10.7 million to 9.6 million). These changes also resulted in a decline in the number of MA enrollees considered to be living in a rural area, from 2.19 million to 1.95 million. However, the percentage of Medicare beneficiaries enrolled in MA and prepaid plans in rural areas declined only slightly from 20.6 percent to 20.3 percent. (2) Rural Medicare Advantage (MA) and other prepaid plan enrollment in March 2014 was nearly 1.95 million, or 20.3 percent of all rural Medicare beneficiaries, an increase of more than 216,000 from March 2013. Enrollment increased to 1.99 million (20.4 percent) in October 2014. (3) In March 2014, 56 percent of rural MA enrollees were enrolled in Preferred Provider Organization (PPO) plans, 29 percent were enrolled in Health Maintenance Organization (HMO) or Point-of-Service (POS) plans, 7 percent were enrolled in Private Fee-for-Service (PFFS) plans, and 8 percent were enrolled in other prepaid plans, including Cost plans and Program of All-Inclusive Care for the Elderly (PACE) plans. (4) States with the highest percentage of rural Medicare beneficiaries enrolled in MA and other prepaid plans include Minnesota (49.1 percent), Hawaii (41.1 percent), Pennsylvania (35.4 percent), Wisconsin (34.3 percent), New York (30.4 percent), and Ohio (30.1 percent).

Who chooses prepaid dental care? A baseline report of a prospective observational study.

BACKGROUND: An optional capitation prepayment system has been implemented in Swedish dental care, supplementary to the traditional fee-for-service scheme within the Public Dental Service. The implementation of a new system may have a variety of preferred and adverse effects, arguably dependent on the individual patient's attitudes, health beliefs and course of action.The aim of this study was to describe potential differences regarding socioeconomic and lifestyle factors, perceived oral health and attitudes towards oral health between patients in the two payment systems. METHODS: Questionnaire data were consecutively collected from 13,719 patients, who regularly attended 20 strategically selected clinics within the PDS in Region Västra Götaland, before they were offered the choice between the traditional and the new payment system. RESULTS: Capitation patients were more often female and well educated. They had healthier habits, were more motivated to follow self-care advice, more often judged their oral health to be very good and considered oral health to be very significant for their wellbeing. The results were statistically significant and described a gradient. CONCLUSIONS: The more explicitly affirmative the answer, the more likely the patient was to choose the prepayment scheme. There appears to be a pattern of differences with respect to important individual views on oral health between patients choosing a capitation system or a fee-for-service system. These differences may be important when assessing outcomes in the new payment system and in public dental care.

[Fatality and hospitalization in hemodialysis patients in a health plan]. / Letalidade e internacoes de pacientes em hemodialise em plano de saude.

OBJECTIVE: To analyze clinical outcomes of patients on hemodialysis linked to health care plan provider. METHODS: Cohort study of hemodialysis events in Belo Horizonte, MG, Southeastern Brazil, between 2004 and 2008, based on records from health care plan provider databases. The independent variables were: sex, age, time between first appointment with nephrologist and starting hemodialysis, type of first vascular access, diabetes mellitus, length of time spent in hospital/year of treatment and death. DEPENDENT VARIABLES: time between starting hemodialysis and death and length of time spent in hospital/year of treatment > 7.5 days. Statistical analysis was carried out using Pearson's Chi-squared test in the univariate analysis for the outcomes 'death' and 'length of time spent in hospital/year of treatment'; the Kaplan-Meier method was used to analyze survival; the Cox model and Poisson regression were used for risk of death and chance of length of time spent in hospital/year of treatment > 7.5 days. The Business Intelligence tool and Stata(r) 10.0 software were used to extract data. RESULTS: There were 311 patients on hemodialysis included in the study, with a mean age of 62 (sd 16.6 years), of whom 55.5% were male. Prevalence increased 160% during the period in question. Survival analysis showed a higher mortality among older patients, patients that did not consult a nephrologists, those whose first vascular access was using a temporary catheter, those with diabetes mellitus, those admitted to hospital within a month of beginning hemodialysis. The Cox model showed that a higher risk of death was associated with age, diabetes mellitus, not consulting a nephrologists and those that were hospitalized within a month of beginning hemodialysis. Greater length of time spent in hospital/year of treatment was not associated with sex or diabetes. According to Poisson regression, the variables were not significant. CONCLUSIONS: Assessment by a specialist before starting hemodialysis decreases the risk of death in cases of chronic kidney disease, whereas the presence of diabetes and being hospitalized within a month of beginning hemodialysis are markers of risk of death.

Supplemental care from a bioethical perspective.

OBJECTIVE: To describe and analyze, from the perspective of Intervention Bioethics, the legal, institutional and ethical contexts, the conflicts and regulations of supplemental health care in Brazil, since the approval of the regulatory law in 1998 until 2010. METHODS: Qualitative research, using Intervention Bioethics as the theoretical reference. Bibliographical and documental study of the legislation, regulations and assistential framework, as well as interviews with members of the Supplemental Health Board. RESULTS: There was improvement in the records and rules of action in private health companies, as well as flow of information, contractual and financial guarantees provided to consumers. Conflicts persist regarding access to services and procedures, price increases, policies on autonomy and medical fees. There is a dispute with the public sector regarding the network of health services, with rising costs and no improvement in quality of care. DISCUSSION: Private participation in health demands comparative assessments and improvement of public-private care regulation, as well as promoting greater balance in the funding and reevaluation of the health care model. CONCLUSION: It is necessary to review the regulatory framework considering the supplementary, complementary or duplicate characteristic of assistance, the social actors involved, bioethical and political issues regarding associations between Supplemental Health Care and the National Health System (SUS).

Can we trust measures of healthcare utilization from household surveys?

BACKGROUND: The research community relies heavily on measures of healthcare utilization from household surveys to understand health seeking choices and to evaluate interventions in developing countries. Such measures are known to suffer from recall problems but there is limited evidence of whether the method of data collection affects evaluation findings. We compared the results of a randomized trial of free healthcare using utilization data from two sources. METHODS: Data are from a study in Ghana, in which 2,194 households containing 2,592 children under 5 y old were randomized into a prepayment scheme providing free primary and some referral care, or to a control group whose families paid user fees for healthcare. Data on morbidity and health seeking behaviour were collected using a standard household survey administered at endline and a pictorial diary given to households over a six month period, collected at monthly intervals. RESULTS: Self-reported measures of morbidity and healthcare utilization were substantially lower in the household survey than the pictorial diary when the recall period was over a month. Introducing free healthcare had a positive effect on primary care visits based on the pictorial diary and a non-significant negative effect according to the household survey. Using any clinic visit in the past month as the outcome, the difference in the effect of free care between the two data collection methods was 3.6 percentage points (p = 0.078). CONCLUSIONS: The findings raise methodological concerns about measures of healthcare utilization from household surveys, particularly in the evaluation of health financing interventions.

Incidence of multiple sclerosis in multiple racial and ethnic groups.

OBJECTIVE: To determine whether the incidence of multiple sclerosis (MS) varies by race/ethnicity in a multiethnic, population-based cohort. METHODS: We conducted a retrospective cohort study of more than 9 million person-years of observation from the multiethnic, community-dwelling members of Kaiser Permanente Southern California health plan from January 1, 2008 to December 31, 2010. Incidence of MS and risk ratios comparing incidence rates between racial/ethnic groups were calculated using Poisson regression. RESULTS: We identified 496 patients newly diagnosed with MS who met McDonald criteria. The average age at diagnosis was 41.6 years (range 8.6-78.3 years) and 70.2% were women. The female preponderance was more pronounced among black (79.3%) than white, Hispanic, and Asian individuals with MS (67.8%, 68.1%, and 69.2%, respectively; p = 0.03). The incidence of MS was higher in blacks (10.2, 95% confidence interval [CI] 8.4-12.4; p < 0.0001) and lower in Hispanics (2.9, 95% CI 2.4-3.5; p < 0.0001) and Asians (1.4, 95% CI 0.7-2.4; p < 0.0001) than whites (6.9, 95% CI 6.1-7.8). Black women had a higher risk of MS (risk ratio 1.59, 95% CI 1.27-1.99; p = 0.0005) whereas black men had a similar risk of MS (risk ratio 1.04, 95% CI = 0.67-1.57) compared with whites. CONCLUSIONS: Our findings do not support the widely accepted assertion that blacks have a lower risk of MS than whites. A possible explanation for our findings is that people with darker skin tones have lower vitamin D levels and thereby an increased risk of MS, but this would not explain why Hispanics and Asians have a lower risk of MS than whites or why the higher risk of MS among blacks was found only among women.

National and state trends in enrollment and spending for dual eligibles under age 65 in Medicaid managed care.

BACKGROUND: To reduce costs and improve care, states are increasingly enrolling individuals with disabilities in Medicaid managed care. Many states allow or require adults who are dually eligible for Medicaid and Medicare to enroll in these plans. OBJECTIVE: This study (1) quantifies changes in enrollment by managed care arrangement for duals under age 65, between 2005 and 2008 and (2) compares enrollment and spending between dual eligibles and Medicaid-only beneficiaries. METHODS: We used Medicaid Analytic eXtract data to compare the Medicaid enrollment and spending for all-year, full-benefit dual eligibles ages 21-64 with that of Medicaid-only Supplemental Security Income (SSI) and disabled beneficiaries. The study population was classified into 9 types of managed care to quantify enrollment and calculate expenditures by year. RESULTS: Nationwide, the proportion of adult duals in managed care increased from 2005 to 2008, with the expansion of prepaid health plans (PHPs) (31.0%-46.6%), particularly behavioral health PHPs, driving the increase. In 2008, Medicaid-only disabled adults were three times as likely as dual adults to enroll in comprehensive managed care (CMC) (35.1% versus 11.7%). Average Medicaid expenditures per enrollee differed markedly by managed care arrangement and state. CONCLUSIONS: From 2005 to 2008, there was little expansion of CMC among adult duals, while the use of PHPs to cover carved out services increased greatly. New federal initiatives aim to reduce barriers to enrolling duals into comprehensive, integrated managed care. With expanded enrollment, it will be important to monitor enrollment and evaluate whether integration improves care.

March 2013: Medicare Advantage update.

Key Data Findings. (1) From March 2012 to March 2013, rural enrollment in Medicare Advantage (MA) and other prepaid plans increased by over 200,000 enrollees, to more than 1.9 million. (2) Preferred provider organization (PPO) plan enrollment increased to nearly one million enrollees, accounting for more than 51% of the rural MA market (up from 48% in March 2012). (3) Health maintenance organization (HMO) enrollment continued to grow in 2013, with over 31% of the rural MA market, while private fee-for-service (PFFS) plan enrollment decreased to less than 10% of market share. (4) Despite recent changes to MA payment, rural MA enrollment continues to increase.

[Cognitive performance and frailty in older adults clients of a private health care plan]. / Desempenho cognitivo e fragilidade em idosos clientes de operadora de saúde.

OBJECTIVE: To investigate the association between frailty syndrome and cognitive performance in the older adults and the effect of schooling and age on this association. METHODS: Data on frailty in older adults from Phase 1 of the FIBRA-RJ Study were analyzed, relating to 737 customers of a private health care provider, aged 65 and over, living in Rio de Janeiro, Southeastern Brazil, between January 2009 and January 2010. Data on socioeconomic and demographic characteristics, medical conditions and functional capacity were collected. Cognitive performance was assessed using the Mini-Mental State Examination (MMSE). Individuals who exhibited three or more of the following features were considered to be frail: unintentional weight loss (≥ 4.5 kg in the last year); feeling self-reported exhaustion, low grip strength, low physical activity level and slowness. The association between frailty and cognitive performance was evaluated using multivariate logistic regression, with adjustment for medical conditions, activities of daily living and socioeconomic variables. We evaluated the age and schooling as possible effect modifiers in this association. RESULTS: The frail subjects had a higher prevalence of low cognitive performance, compared to not frail or pre-frail, in the three age groups studied (65-74; 75-84; ≥ 85 years), p < 0.001. After adjustment, the association between frailty and cognitive performance was found among older adults individuals aged 75 and older, with an OR(adj)= 2.78 (95%CI 1.23;6.27) for those aged 75 to 84 and OR(adj)= 15.62 (95%CI 2.20;110.99) for 85 and older. The age variable was an effect modifier in the association between frailty and cognitive performance, χ²(5) = 806.97, p < 0.0001; the same was not the case with schooling. CONCLUSIONS: Frailty syndrome is associated with cognitive performance in the aging. Age proved to be an effect modifier in this association. The oldest patients showed a more significant association between the two phenomena.
