Pathways of influence on equity in health.

An increasing number of studies are documenting the existence of inequities, and attention is now turning to exploring pathways through which they are generated and might be attacked. This appears to be an opportune time to consider what has been learned and what future directions might be taken by researchers to fill gaps in knowledge and make research more useful for policy interventions. This commentary briefly reviews some of the main contributions of past research that have possible relevance to pathways, considers what those pathways might include, and concludes with implications for future research. It makes the case for a conceptualization of influences on equity that explicitly includes distribution of health as an outcome as well as characteristics of the society as influences.

[Internal consistency and reliability of Primary Care Assessment Tool (PCATool-Brasil) for child health services].

Health strategies based on primary health care have been expanding in Brazil. An instrument applied to users, the Primary Care Assessment Tool (the PCATool), which measures the extent of primary care, has been validated in the United States. We sought to adapt the PCATool to Brazil and analyze its validation and reliability through a cross-sectional validation study of the Child PCATool. Validation included: translation, back-translation, adaptation, debriefing, content and construct validate, internal consistency, and reliability analysis. The questionnaire was applied to 468 parents or guardians of children registered with 18 primary health services in Porto Alegre, representing the services' normal pediatric population. Using factor analysis, 8 domains were identified, with Cronbach's aranging from 0.74 to 0.88. Validation resulted in a 45-item scale, divided into 8 attributes (Access to First Contact, Continuity, Coordination, 3 attributes of Comprehensiveness, Community Orientation, and Family Orientation). These results showed that the PCATool-Brasil has adequate validity and reliability and could be used as a national instrument to evaluate primary health care after its application to other population settings in the country.

Perceived health status and use of healthcare services among children and adolescents.

BACKGROUND: The aim of the present study was to analyse the use of healthcare services according to health status in a population of children and adolescents, taking into account family socio-demographic characteristics and characteristics of the proxy respondent. METHODS: A total of 836 interviews of proxy respondents for children aged 5-14 years from the Barcelona Health Interview Survey carried out in 2000 were included. Dependent variables were visits to a healthcare professional, visits to the emergency room, and hospitalization. Independent variables were: report of medical conditions, health status of the child measured by the Child Health and Illness Profile-Child Edition, Parent Report Form (CHIP-CE/PRF), the educational level of the head of household, social class, child's healthcare coverage, and proxy-related variables [mental health status by means of the General Health Questionnaire-12 items version (GHQ-12), and other]. Logistic regression analysis was used to estimate prevalence ratio (PR) to compare the use of healthcare services among different categories of independent variables. RESULTS: Children having worse health status were more likely to have visited a healthcare professional [PR = 1.68; 95% confidence interval (95% CI) = 1.09-3.83], whereas children with a reported medical condition were more likely to have made a visit to the emergency service (PR = 1.47; 95% CI = 1.27-2.55) and were hospitalized more frequently (PR = 2.50; 95% CI = 1.12-5.57). Higher likelihood of visits to the emergency room was associated with children having both public and private coverage and a proxy respondent scoring 3 or higher on the GHQ-12. CONCLUSIONS: Use of healthcare services differed by health needs but not by social class. Double healthcare coverage and mental distress of the proxy respondent influenced the use of emergency services.

State of the art in research on equity in health.

This essay provided the introduction to a workshop in Bellagio, Italy, on the subject of translating research into policy for equity in health. The essay first defines equity in a way that facilitates its assessment and monitoring and then summarizes evidence from existing research. Directions for developing policy strategies follow from these principles. The role of health services in influencing the distribution of health in populations is discussed in the special context of primary-care-oriented health systems that are, at the same time, more effective, more efficient, and more equity producing than is the case for specialist-dominated health systems.

Primary care, race, and mortality in US states.

This study used US state-level data from 1985 to 1995 to examine the relationship of primary care resources and income inequality with all-cause mortality within the entire population, and in black and white populations. The study is a pooled ecological design with repeated measures using 11 years of state-level data (n=549). Analyses controlled for socioeconomic and demographic characteristics. Contemporaneous and time-lagged covariates were modeled, and all analyses were stratified by race/ethnicity. In all models, primary care was associated with lower mortality. An increase of one primary care doctor per 10,000 population was associated with a reduction of 14.4 deaths per 100,000. The magnitude of primary care coefficients was higher for black mortality than for white mortality. Income inequality was not associated with mortality after controlling for state-level sociodemographic covariates. The study provides evidence that primary care resources are associated with population health and could aid in reducing socioeconomic disparities in health.

Contribution of primary care to health systems and health.

Evidence of the health-promoting influence of primary care has been accumulating ever since researchers have been able to distinguish primary care from other aspects of the health services delivery system. This evidence shows that primary care helps prevent illness and death, regardless of whether the care is characterized by supply of primary care physicians, a relationship with a source of primary care, or the receipt of important features of primary care. The evidence also shows that primary care (in contrast to specialty care) is associated with a more equitable distribution of health in populations, a finding that holds in both cross-national and within-national studies. The means by which primary care improves health have been identified, thus suggesting ways to improve overall health and reduce differences in health across major population subgroups.

Primary care, social inequalities, and all-cause, heart disease, and cancer mortality in US counties, 1990.

OBJECTIVES: We tested the association between the availability of primary care and income inequality on several categories of mortality in US counties. METHODS: We used cross-sectional analysis of data from counties (n=3081) in 1990, including analysis of variance and multivariate ordinary least squares regression. Independent variables included primary care resources, income inequality, and sociodemographics. RESULTS: Counties with higher availability of primary care resources experienced between 2% and 3% lower mortality than counties with less primary care. Counties with high income inequality experienced between 11% and 13% higher mortality than counties with less inequality. CONCLUSIONS: Primary care resources may partially moderate the effects of income inequality on health outcomes at the county level.

Does community-governed nonprofit primary care improve access to services? Cross-sectional survey of practice characteristics.

This study compared community-governed nonprofit and for-profit primary care practices in New Zealand to test two hypotheses: (1) nonprofits reduce financial and cultural barriers to access; and (2) nonprofits do not differ from for-profits in equipment, services, service planning, and quality management. Data were obtained from a nationally representative cross-sectional survey of GPs. Practices were categorized by ownership status: private community-governed nonprofit or private for-profit. Community-governed nonprofits charged lower patient fees per visit and employed more Maori and Pacific Island staff, thus reducing financial and cultural barriers to access compared with for-profits. Nonprofits provided a different range of services and were less likely to have specific items of equipment; they were more likely to have written policies on quality management, complaints, and critical events, and to carry out locality service planning and community needs assessments. The findings support the shift to nonprofit community governance occurring in New Zealand and elsewhere.

Wage inequality, the health system, and infant mortality in wealthy industrialized countries, 1970-1996.

This pooled, cross-sectional, time-series study assesses the impact of health system variables on the relationship between wage inequality and infant mortality in 19 OECD countries over the period 1970-1996. Data are derived from the OECD, World Value Surveys, Luxembourg Income Study, and political economy databases. Analyses include Pearson correlation and fixed-effects multivariate regression. In year-specific and time-series analyses, the Theil measure of wage inequality (based on industrial sector wages) is positively and statistically significantly associated with infant mortality rates--even while controlling for GDP per capita. Health system variables--in particular the method of healthcare financing and the supply of physicians--significantly attenuated the effect of wage inequality on infant mortality. In fixed effects multivariate regression models controlling for GDP per capita and wage inequality, variables generally associated with better health include income per capita, the method of healthcare financing, and physicians per 1000 population. Alcohol consumption, the proportion of the population in unions, and government expenditures on health were associated with poorer health outcomes. Ambiguous effects were seen for the consumer price index, unemployment rates, the openness of the economy, and voting rates. This study provides international evidence for the impact of wage inequalities on infant mortality. Results suggest that improving aspects of the healthcare system may be one way to partially compensate for the negative effects of social inequalities on population health.

The role of primary care in preventing ambulatory care sensitive conditions.

BACKGROUND: To examine the postulated relationship between Ambulatory Care Sensitive Conditions (ACSC) and Primary Health Care (PHC) in the US context for the European context, in order to develop an ACSC list as markers of PHC effectiveness and to specify which PHC activities are primarily responsible for reducing hospitalization rates. METHODS: To apply the criteria proposed by Solberg and Weissman to obtain a list of codes of ACSC and to consider the PHC intervention according to a panel of experts. Five selection criteria: i) existence of prior studies; ii) hospitalization rate at least 1/10,000 or 'risky health problem'; iii) clarity in definition and coding; iv) potentially avoidable hospitalization through PHC; v) hospitalization necessary when health problem occurs. Fulfilment of all criteria was required for developing the final ACSC list. A sample of 248,050 discharges corresponding to 2,248,976 inhabitants of Catalonia in 1996 provided hospitalization rate data. A Delphi survey was performed with a group of 44 experts reviewing 113 ICD diagnostic codes (International Classification of Diseases, 9th Revision, Clinical Modification), previously considered to be ACSC. RESULTS: The five criteria selected 61 ICD as a core list of ACSC codes and 90 ICD for an expanded list. CONCLUSIONS: A core list of ACSC as markers of PHC effectiveness identifies health conditions amenable to specific aspects of PHC and minimizes the limitations attributable to variations in hospital admission policies. An expanded list should be useful to evaluate global PHC performance and to analyse market responsibility for ACSC by PHC and Specialist Care.

The Parent Report Form of the CHIP-Child Edition: reliability and validity.

BACKGROUND: Valid, comprehensive instruments to describe, monitor, and evaluate health from childhood through adolescence are almost nonexistent, but are critical for health resource planning, evaluation of policy, preventive, and clinical interventions, and understanding trajectories of health during this important period of life. OBJECTIVES: The objectives of this study were to describe the development, testing, and final versions of the Parent Report Form of the Child Health and Illness Profile-Child Edition (CHIP-CE/PRF), designed to measure the health of children 6 to 11 years old from the caregiver perspective. METHODS: Parents (N=1049) completed a version of the CHIP-CE/PRF in 4 locations in the United States, either in clinic waiting rooms or their homes. They differed in race/ethnicity, socioeconomic level, and native language. RESULTS: The Parent CHIP-CE is feasible; parents with a 5th-grade reading level complete the 76-item PRF in 20 minutes. Its domains (Satisfaction, Comfort, Risk Avoidance, Resilience, and Achievement) measure structurally distinct, interrelated aspects of health. Domain reliability is high: internal consistency=0.79-0.88; retest reliability (ICC)=0.71-0.85. Validity is supported. The scale scores are sensitive to predicted age, gender, and socioeconomic status differences in health. CONCLUSION: The CHIP-Child Edition/Parent Report Form is a psychometrically sound, conceptually based measure of child health that works well in diverse populations. It produces scores that parallel those of children on the CHIP-CE/CRF and adolescents on the CHIP-AE and allows health to be consistently assessed from childhood through adolescence. It should meet many needs for describing, monitoring, and understanding child health and evaluating outcomes of interventions.
