Clinical care and health disparities.

Health disparities, also known as health inequities, are systematic and potentially remediable differences in one or more aspects of health across population groups defined socially, economically, demographically, or geographically. This topic has been the subject of research stretching back at least decades. Reports and studies have delved into how inequities develop in different societies and, with particular regard to health services, in access to and financing of health systems. In this review, we consider empirical studies from the United States and elsewhere, and we focus on how one aspect of health systems, clinical care, contributes to maintaining systematic differences in health across population groups characterized by social disadvantage. We consider inequities in clinical care and the policies that influence them. We develop a framework for considering the structural and behavioral components of clinical care and review the existing literature for evidence that is likely to be generalizable across health systems over time. Starting with the assumption that health services, as one aspect of social services, ought to enhance equity in health care, we conclude with a discussion of threats to that role and what might be done about them.

Papel del pediatra de atención primaria y coordinación con atención especializada / Role of paediatrics in primary care and coordination with specialist care

Objetivos: Conocer cómo asumen y desempeñan los médicos de asistencia infantil en Cataluña los atributos de la atención primaria (AP) (coordinación, globalidad y longitudinalidad). Material y métodos: Estudio cualitativo basado en grupos de discusión y entrevistas individuales semiestructuradas con pediatras cuyo perfil había sido definido previamente según características sociodemográficas y de formación. Se llevaron a cabo 2 grupos de discusión (5 y 4 personas respectivamente) y 5 entrevistas individuales. Los participantes respondieron dos preguntas: ¿cómo explicaríais vuestra función como pediatras de AP? y ¿cuál es vuestra opinión sobre la relación entre los pediatras de AP y los especialistas a los que deriváis a los pacientes? Se llevó a cabo un análisis de contenido temático. Resultados: Los pediatras asumen que la AP debe ser integral y tener en cuenta el contexto del niño/a. El vínculo que se establece con las familias es una característica definitoria de su función. Detectan deficiencias en su propia formación y escaso reconocimiento social e institucional de su trabajo. La coordinación con la atención especializada y la transferencia de información entre niveles no son satisfactorias. Se identifican como factores facilitadores el conocimiento personal, la formación común y las sesiones clínicas. Conclusión: A pesar de su formación hospitalaria, los pediatras asumen los atributos de la AP. Se propone abordar los aspectos deficitarios, como la falta de formación en AP, y tener en cuenta el escaso reconocimiento institucional y social, así como las dificultades en la coordinación, para mantener un nivel de calidad elevado en la atención primaria a la población infantil (AU)

Objectives: Primary care (PC) paediatricians are trained mainly in the hospital setting, with little contact with PC. This study aimed to find out what perceptions and experiences they have on the attributes of PC (first contact, comprehensiveness and continuity of care) that are assumed and performed by PC paediatricians. Material and methods: A qualitative study was performed based on focus groups and semi-structured individual interviews with paediatricians with pre-defined sociodemographic and speciality training characteristics. Two focus groups (5 and 4 people each) and 5 interviews were made. Participants responded to two questions: how would you explain your function as a primary care paediatrician? and what is your opinion on the relationship between primary care paediatricians and the specialists to whom your patients are referred? The conversations of the groups and interviews were recorded and transcribed, and a content analysis was performed. Results: Paediatricians assume that PC must be comprehensive, and take into account the context of the child. Paediatricians declare a lack in their training and poor social and institutional recognition. Coordination with specialists and the transfer of information are not satisfactory. Helpful factors are personal knowledge, the shared training and the face-to-face clinical sessions. Conclusion: Despite their hospital-based training, paediatricians assume the attributes of PC. Difficulties in performing their function include poor adaptation of their training to PC, and little institutional and social recognition. Coordination with specialists is not satisfactory. Approaching these difficulties can help maintaining a high quality level in the care of the paediatric population (AU)

Concordancia entre padres e hijos en la calidad de vida relacionada con la salud en niños con trastorno por déficit de atención con hiperactividad: estudio longitudinal / Parent-child agreement in the health related quality of life (HRQOL) of children with attention-deficit/hyperactivity disorder (ADHD): A longitudinal study

Objetivos: Evaluar la concordancia entre padres e hijos sobre los cambios producidos en la calidad de vida relacionada con la salud (CVRS) de niños tratados por trastorno por déficit de atención con hiperactividad (TDAH) durante un corto período de tiempo y comparar las puntuaciones con las normas de referencia de la población general. Métodos: Estudio prospectivo en niños de 6 a 12 años con TDAH. Los padres y sus hijos completaron la versión española del CHIP-CE (Child Health and Illness Profile-Child Edition ‘Perfil de salud infantil’) al iniciar el tratamiento y a las 8 semanas. Las puntuaciones del CHIP-CE de ambas visitas se compararon mediante el test de la t de Student para datos apareados, el tamaño del efecto (TE), los coeficientes de correlación intraclase (CCI) y los diagramas de dispersión. Las evaluaciones de padres e hijos se compararon con las puntuaciones del CHIP-CE de la muestra de referencia española. Resultados: En el análisis se incluyó a 31 niños y a sus padres. El mayor cambio entre la visita inicial y la visita de seguimiento se produjo en la dimensión de riesgos, tanto en los niños como en los padres (TE=0,24 y 0,49, respectivamente). El CCI presentó un intervalo de entre 0,44 (satisfacción) y 0,01 (riesgos). Las puntuaciones de los niños fueron similares a los valores de referencia poblacional. Todas las dimensiones de la versión de padres del CHIP-CE presentaron puntuaciones medias estandarizadas inferiores a los valores de referencia en la visita inicial y fueron próximas a los valores de referencia tras el tratamiento. Conclusiones: El presente estudio mostró poca concordancia entre padres e hijos y sugiere que se deberían recoger ambas perspectivas en futuros estudios del impacto y del tratamiento del TDAH (AU)

Objectives: To assess parent-child agreement on changes over a short-term period of time in the HRQOL of children treated for ADHD over a short period of time, and to compare child and parent ratings of children with ADHD with general population norms. Methods: Prospective study in children 6-12 years old with ADHD. Children and parents completed the Spanish versions of the Child Health and Illness Profile-Child Edition (CHIP-CE) before and after 8 weeks of treatment. CHIP-PE scores at both visits were compared using paired t tests and effect sizes (ES), intra-class correlation coefficients (ICC), and scatter plots. Child and parent ratings were compared with CHIP-CE scores for a general population sample. Results: Thirty-one children and parents were included in the analysis. The highest change between the first and the follow-up visit was on the Risk Avoidance domain both children and parents (effect size [ES]=0.24 and 0.40, respectively). The ICC ranged from 0.44 (Satisfaction) to 0.01 (Risk avoidance). Child self-ratings were close to general population values. All domains of the parent version presented standardized means below the reference values at the baseline visit and closer to the general population norm after treatment. Conclusions: This study found poor parent-child agreement and suggests that both ratings should be collected in future studies on the impact of ADHD and treatment effectiveness (AU)

The concept of prevention: a good idea gone astray?

Over time, the definition of prevention has expanded so that its meaning in the context of health services is now unclear. As risk factors are increasingly considered to be the equivalent of "diseases" for purposes of intervention, the concept of prevention has lost all practical meaning. This paper reviews the inconsistencies in its utility, and suggests principles that it should follow in the future: a population orientation with explicit consideration of attributable risk, the setting of priorities based on reduction in illness and avoidance of adverse effects, and the imperative to reduce inequities in health.

Primary care, social inequalities and all-cause, heart disease and cancer mortality in US counties: a comparison between urban and non-urban areas.

OBJECTIVE: The objective of this study was to test whether the association between primary care and income inequality on all-cause, heart disease and cancer mortality at county level differs in urban (Metropolitan Statistical Area-MSA) compared with non-urban (non-MSA) areas. STUDY DESIGN: The study consisted of a cross-sectional analysis of county-level data stratified by MSA and non-MSA areas in 1990. Dependent variables included age and sex-standardized (per 100,000) all-cause, heart disease and cancer mortality. Independent variables included primary care resources, income inequality, education levels, unemployment, racial/ethnic composition and income levels. METHODS: One-way analysis of variance and multivariate ordinary least squares regression were employed for each health outcome. RESULTS: Among non-MSA counties, those in the highest income inequality category experienced 11% higher all-cause mortality, 9% higher heart disease mortality, and 9% higher cancer mortality than counties in the lowest income inequality quartile, while controlling for other health determinants. Non-MSA counties with higher primary care experienced 2% lower all-cause mortality, 4% lower heart disease mortality, and 3% lower cancer mortality than non-MSA counties with lower primary care. MSA counties with median levels of income inequality experienced approximately 6% higher all-cause mortality, 7% higher heart disease mortality, and 7% higher cancer mortality than counties in the lowest income inequality quartile. MSA counties with low primary care (less than 75th percentile) had significantly lower levels of all-cause, heart disease and cancer mortality than those counties with high primary care. CONCLUSIONS: In non-MSA counties, increasing primary physician supply could be one way to address the health needs of rural populations. In MSA counties, the association between primary care and health outcomes appears to be more complex and is likely to require intervention that focuses on multiple fronts.

Primary care, infant mortality, and low birth weight in the states of the USA.

STUDY OBJECTIVE: The study tests the extent to which primary care physician supply (office based primary care physicians per 10 000 population) moderates the association between social inequalities and infant mortality and low birth weight throughout the 50 states of the USA. DESIGN: Pooled cross sectional, time series analysis of secondary data. Analyses controlled for state level education, unemployment, racial/ethnic composition, income inequality, and urban/rural differences. Contemporaneous and time lagged covariates were modelled. SETTING: Eleven years (1985-95) of data from 50 US states (final n = 549 because of one missing data point). MAIN RESULTS: Primary care was negatively associated with infant mortality and low birth weight in all multivariate models (p<0.0001). The association was consistent in contemporaneous and time lagged models. Although income inequality was positively associated with low birth weight and infant mortality (p<0.0001), the association with infant mortality disappeared with the addition of sociodemographic covariates. CONCLUSIONS: In US states, an increased supply of primary care practitioners-especially in areas with high levels of social disparities-is negatively associated with infant mortality and low birth weight.

[Reference population values for the Spanish Child Health and Illness Profile-Adolescent Edition (CHIP-AE) using a representative school-based sample]. / Valores poblacionales de referencia del perfil de salud CHIP-AE a partir de una muestra representativa de adolescentes escolarizados.

AIM: The Child Health and Illness Profile (CHIP-AE) is a generic health status instrument for adolescents aged 12-19 years adapted for use in Spain. The aim of this study was to obtain reference population values of the Spanish version of the CHIP-AE. METHODS: The CHIP-AE was administered to a representative sample of adolescents from schools in Barcelona. The sample was selected by using cluster-sampling, stratified by type of school (public or private) and an ecological socioeconomic index (Indice de Capacidad Familiar: low, middle, and high). The CHIP-AE scores were standardized to a mean of 20 and a standard deviation (SD) of 5. Means and percentiles were computed. Means were compared by age, gender, and socioeconomic status using analysis of variance. RESULTS: The response rate was 81% (n = 902). The distribution of the CHIP-AE scores presented a wide range with scores generally skewed toward positive health status. Nevertheless, the results suggest that the sample selected from a general population was not free of health problems. Twenty-five percent of adolescents presented scores below 17.2 in the domain of discomfort, indicating an effect size of 0.56 standardized SD units. The distribution of scores in the reference samples from Barcelona was similar to the original results in Baltimore (USA), with some marginal differences in individual risks. CONCLUSIONS: The CHIP-AE systematically gathers information on health domains in adolescents. The results from this reference sample will allow comparisons with adolescents from other regions, and/or with different health problems, as well as description of inequalities in health during adolescence.

Valores poblacionales de referencia del perfil de salud CHIP-AE a partir de una muestra representativa de adolescentes escolarizados / Reference population values for the Spanish Child Health and Illness Profile-Adolescent Edition [CHIP-AE] using a representative school-based sample

Objetivo: El perfil de salud CHIP-AE (Child Health and Illness Profile, Adolescent Edition) es un instrumento genérico para adolescentes de 12 a 19 años que ha sido adaptado para uso en España. El objetivo del estudio fue obtener los valores poblacionales de referencia de la versión española del CHIP-AE. Métodos: Se administró el CHIP-AE a una muestra representativa de adolescentes escolarizados de Barcelona, mediante muestreo por conglomerados, estratificado según la titularidad del centro (público o concertado) y el índice de capacidad económica familiar (bajo, medio y alto). Se estandarizaron las puntuaciones a una media de 20 y desviación estándar (DE) de 5. Se calcularon las medias y los percentiles. Las medias se compararon por edad, género y nivel socioeconómico mediante análisis de la varianza. Resultados: Las proporción de respuesta fue del 81 por ciento (n = 902). Las puntuaciones presentaron un amplio rango de distribución, y aunque en general fueron algo sesgadas hacia las puntuaciones de buena salud, sugieren que la muestra de población general no está exenta de problemas de salud. El 25 por ciento presentó puntuaciones por debajo de 17,2 en la dimensión de bienestar, lo que indica un tamaño de efecto de 0,56 unidades estandarizadas de DE. La distribución de las puntuaciones de las muestras de referencia de Barcelona fueron muy similares a las originales de Baltimore (Estados Unidos), con diferencias mínimas en riesgo individual. Conclusiones: El CHIP-AE recoge de manera sistemática las dimensiones propias de la salud de los adolescentes. Los resultados permitirán establecer comparaciones con adolescentes de otras regiones, y/o con diferentes problemas de salud y analizar las desigualdades en salud durante la adolescencia (AU)

The Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE).

The aim of the study was to obtain a conceptually equivalent Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE), and to test its feasibility, reliability and preliminary construct validity. The methodology used for adaptation was forward-back translation, including two focus groups with adolescents and a panel of experts. Reliability and validity were assessed in healthy convenience samples from school settings (n = 417). Three different illness groups (n = 67) were used to examine differences in health status between healthy, acutely ill, chronically ill and mentally ill adolescents. Preliminary construct validity was examined by comparing mean scores for each of the subdomains to determine if they differed in predicted ways according to age, gender and illness group. The majority of items (154 out of 203) were conceptually equivalent to the original version. Some items (46) had to be modified to increase clarity and/or to adapt them for use in Spain and 3 items were considered not applicable. Single construct subdomains achieved alpha coefficients between 0.65 and 0.92, and intraclass correlation coefficients (ICC) between 0.57 and 0.93. The mentally ill group presented the worst scores in most domains. The Spanish CHIP-AE is acceptable for Spanish adolescents and shows adequate metric characteristics, which are similar to those reported in the US version.

Social class gradients in health during adolescence.

STUDY OBJECTIVE: To review existing data on social class gradients in adolescent health and to examine whether such gradients exist in new data concerning US adolescents. DESIGN: Review of relevant publications and unpublished data; regression analyses using adolescent self reported health status data to determine whether there are gradients by social class, using three classes categorised by adolescent reported parental work status and education. PARTICIPANTS: Adolescents of ages 11-17. MAIN RESULTS: Findings from the literature indicate the presence of social class gradients in some but not all aspects of adolescent health. Results from new data showed social class gradients in several domains of health and in profiles of health. The likelihood of being satisfied with one's health, of being more resilient (better family involvement, better problem solving, more physical activity, better home safety), having higher school achievement, and of being in the best health profiles were significantly and progressively greater as social class rose. Moreover, the probability of being in the poorest health profile type group was progressively higher as social class declined. CONCLUSIONS: The review of existing data and the new findings support the existence of social class gradients in satisfaction with one's health, in resilience to health threats, in school achievement, and in being in the best health overall (as manifested by the health profiles composed of four major domains of health). The study had two especially notable findings: (1) the paucity of studies using the same or similar indicators, and (2) the consistent existence of social class gradients in characteristics related to subsequent health, particularly intake of nutritional foods and physical activity. The sparseness of existing data and the different aspects of health investigated in the relatively few studies underscore the need for (1) the development of conceptual models specifically focused on adolescent health and social class; (2) additional inquiry into the measurement of social class and adolescent perceptions of class; (3) inclusion of contextual variables in study design; and (4) longitudinal cohort studies to better understand the specific determinants of health during adolescence.

[Primary health care and hospitalizations in ambulatory care sensitive conditions in Catalonia]. / La Atención Primaria de Salud y las hospitalizaciones por Ambulatory Care Sensitive Conditions en Cataluña.

BACKGROUND: Ambulatory Care Sensitive Conditions (ACSC) are a set of selected codes of hospital discharge diagnosis intended to measure avoidable hospitalizations. Primary Health Care Services may avoid the hospitalizations due to ACSC by applying any of the following interventions, that are characteristics of this level of care: a) primary prevention; b) secondary prevention, and c) tertiary prevention and rehabilitation. METHODS: Observational, cross-sectional pilot study on 248,174 hospital discharges, from a population of 2,248,704 inhabitants in 161 Basic Health Care Units (BHCU), recorded in the minimum basic set of hospital discharge data in Catalonia during 1996. The complete list of diagnostic codes of ACSC, identified in the literature search, has been used. Crude and age-standardised hospitalisation rates have been estimated. Standardised hospitalisation ratio (SHR) has been computed to compare hospitalisation rates between BHCU. To analyse the effect of variables associated with high ACSC admission rates, multivariate analysis has been carried out by means of Poisson's regression. RESULTS: Hospitalisation due to ACSC account for 13% of all hospitalizations and 16% of hospital stay days. Acute and chronic diseases of the lower respiratory tract are the first cause of hospitalisation at any age group (< 5, 15-64 and > or = 65 years). The most common diagnostic groups, for all ages are respiratory disorders (acute and chronic diseases of the lower respiratory tract and pneumonia) and urinary tract conditions (pyelonephritis/urinary tract infection). The so-called self-limited health problems (ear, nose and throat mild infections/infections of the upper respiratory tract, febrile convulsions in children and gastroenteritis) account for more than 10% of all hospitalizations by ACSC, 45% of which occur in children. The overall crude hospitalisation rate by ACSC is 146.9/10,000 inhabitants (range: 12.4/10,000-239.9/10,000). SHR ranges from 0.01 to 1.85. CONCLUSIONS: "Hospital admissions due to ACSC" is a valid indicator to assess global performance of Primary Health Care and it identifies a part of hospital activity that is amenable to be cared for at Primary Health Care level and therefore potentially avoidable.

The utility of social capital in research on health determinants.

Social capital has become a popular subject in the literature on determinants of health. The concept of social capital has been used in the sociological, political science, and economic development literatures, as well as in the health inequalities literature. Analysis of its use in the health inequalities literature suggests that each theoretical tradition has conceptualized social capital differently. Health researchers have employed a wide range of social capital measures, borrowing from several theoretical traditions. Given the wide variation in these measures and an apparent lack of consistent theoretical or empirical justification for their use, conclusions about the likely role of "social capital" on population health may be overstated or even misleading. Elements of a research agenda are proposed to further elucidate the potential role of factors currently subsumed under the rubric of "social capital."

Improving equity in health: a research agenda.

Equity in health and health care have become important priorities for the world. If efforts at achieving equity are to have any basis in evidence concerning which strategies are likely to work, a research agenda is necessary. An adequate research agenda requires a knowledge of what the problem is, an understanding of the genesis and correlates of the problem, methods to measure these correlates, and rigorous testing of alternative explanations and interventions. This article presents a working definition of equity in health and health services, a conceptual framework in which to view the various types of influence on health and distribution of health in populations, a summary of evidence on the effects of some of these categories, and a research agenda for guiding efforts to improve knowledge on which to base interventions that enhance the attainment of equity. Because of their relative neglect in the existing literature on equity in health, the special roles of political forces and of primary care as a particularly key element of health services are stressed.

La atención primaria de Salud y las hospitalizaciones por Ambulatory Care Sensitive Conditions en Cataluña / Primary Health Care and hospital admissions due to Ambulatory Care Sensitive Conditions in Catalonia

Introducción. Los Ambulatory Care Sensitive Conditions (ACSC) son los códigos de diagnóstico de alta hospitalaria que pretenden servir de medida de hospitalizaciones que se consideran potencialmente evitables. La Atención Primaria podría evitar el ingreso de los ACSC mediante alguna de las siguientes intervenciones propias de este nivel asistencial: a) prevención primaria; b) prevención secundaria, o c) prevención terciaria y rehabilitación.Material y métodos. Estudio piloto observacional transversal de 248.174 altas hospitalarias, generadas por 2.248.704 habitantes de 161 Áreas Básicas de Salud (ABS) registradas en el conjunto mínimo básico de alta hospitalaria de Cataluña del año 1996. Se ha utilizado el listado completo de códigos de diagnóstico de ACSC identificados en la literatura. Se han calculado las tasas de hospitalización bruta y estandarizada. Para comparar las tasas de hospitalización entre ABS se ha calculado la razón de hospitalización estandarizada (RHE). El efecto de las variables asociadas a las tasas de hospitalización se ha estudiado mediante la regresión de Poisson. Resultados. Las hospitalizaciones por ACSC representan el 13 por ciento del total de las hospitalizaciones y el 16 por ciento de las estancias hospitalarias. Las enfermedades agudas y crónicas de las vías respiratorias bajas son la primera causa de hospitalización para los tres grupos de edad (< 15, 15-64 y 65). Los grupos de diagnósticos más frecuentes para todas las edades son la patología respiratoria (enfermedades agudas y crónicas de las vías respiratorias bajas y neumonía) y la patología del tracto urinario (pielonefritis/infección del tracto urinario). La patología denominada autolimitada (las infecciones otorrinolaringológicas no graves/infecciones de vías respiratorias altas, las convulsiones febriles infantiles, los problemas dentales y las gastroenteritis) representa más del 10 por ciento del total de las hospitalizaciones por ACSC, el 45 por ciento de las cuales se presenta en niños. La tasa cruda de hospitalización por ACSC para el conjunto de las ABS estudiadas es de 146,9/10.000, siendo el intervalo de las tasas crudas observadas de 12,4 a 239,9/10.000. El intervalo de la RHE fue de 0,01 a 1,85. Conclusiones. Las hospitalizaciones por ACSC son un indicador que se considera válido para evaluar la capacidad de resolución global de la Atención Primaria e identifica un volumen de actividad hospitalaria susceptible de cuidados del primer nivel asistencial y, por tanto, potencialmente evitable (AU)
