Abstract
INTRODUCTION Avoidable hospitalizations are considered preventable given effective and timely primary care management and are an important indicator of health system performance. The ability to predict avoidable hospitalizations at the population level represents a significant advantage for health system decision-makers that could facilitate proactive intervention for ambulatory care-sensitive conditions (ACSCs). The aim of this study is to develop and validate the Avoidable Hospitalization Population Risk Tool (AvHPoRT) that will predict the 5-year risk of first avoidable hospitalization for seven ACSCs using self-reported, routinely collected population health survey data. METHODS AND ANALYSIS The derivation cohort will consist of respondents to the first 3 cycles (2000/01, 2003/04, 2005/06) of the Canadian Community Health Survey (CCHS) who are 18-74 years of age at survey administration and a hold-out data set will be used for external validation. Outcome information on avoidable hospitalizations for 5 years following the CCHS interview will be assessed through data linkage to the Discharge Abstract Database (1999/2000-2017/2018) for an estimated sample size of 394,600. Candidate predictor variables will include demographic characteristics, socioeconomic status, self-perceived health measures, health behaviors, chronic conditions, and area-based measures. Sex-specific algorithms will be developed using Weibull accelerated failure time survival models. The model will be validated both using split set cross-validation and external temporal validation split using cycles 2000-2006 compared to 2007-2012. We will assess measures of overall predictive performance (Nagelkerke R2), calibration (calibration plots), and discrimination (Harrell's concordance statistic). Development of the model will be informed by the Transparent Reporting of a multivariable prediction model for Individual Prognosis or Diagnosis (TRIPOD) statement. ETHICS AND DISSEMINATION This study was approved by the University of Toronto Research Ethics Board. The predictive algorithm and findings from this work will be disseminated at scientific meetings and in peer-reviewed publications.

Abstract
OBJECTIVE To investigate interdistrict variations in childhood ambulatory sensitive hospitalisation (ASH) over the years. DESIGN Observational population-based study over 2008-2018 using the Primary Health Organisation Enrolment Collection (PHO) and the National Minimum Dataset hospital events databases. SETTING New Zealand primary and secondary care. PARTICIPANTS All children aged 0-4 years enrolled in the PHO Enrolment Collection from 2008 to 2018. MAIN OUTCOME MEASURE ASH. RESULTS Only 1.4% of the variability in the risk of having childhood ASH (intracluster correlation coefficient=0.014) is explained at the level of District Health Board (DHB), with the median OR of 1.23. No consistent time trend was observed for the adjusted childhood ASH at the national level, but the DHBs demonstrated different trajectories over the years. Ethnicity (being a Pacific child) followed by deprivation demonstrated stronger relationships with childhood ASH than the geography and the health system input variables. CONCLUSION The variation in childhood ASH is explained only minimal at the DHB level. The sociodemographic variables also only partly explained the variations. Unlike the general ASH measure, the childhood ASH used in this analysis provides insights into the acute conditions sensitive to primary care services. However, further information would be required to conclude this as the DHB-level performance variations.

Abstract
Particulate matter exposure is a risk factor for lower respiratory tract infection in children. Here, we investigated the geospatial patterns of community-acquired pneumonia and the impact of PM2.5 (particulate matter with an aerodynamic diameter ≤2.5 µm) on geospatial variability of pneumonia in children. We performed a retrospective analysis of prospectively collected population-based surveillance study data of community-acquired pneumonia hospitalizations among children <18 years residing in the Memphis metropolitan area, who were enrolled in the Centers for Disease Control and Prevention sponsored Etiology of Pneumonia in the Community (EPIC) study from January 2010 to June 2012. The outcome measure, residence in high- and low-risk areas for community-acquired pneumonia, was determined by calculating pneumonia incidence rates and performing cluster analysis to identify areas with higher/lower than expected rates of community-acquired pneumonia for the population at risk. High PM2.5 was defined as exposure to PM2.5 concentrations greater than the mean value (>10.75 μg/m3), and low PM2.5 is defined as exposure to PM2.5 concentrations less than or equal to the mean value (≤10.75 μg/m3). We also assessed the effects of age, sex, race/ethnicity, history of wheezing, insurance type, tobacco smoke exposure, bacterial etiology, and viral etiology of infection. Of 810 (96.1%) subjects with radiographic community-acquired pneumonia, who resided in the Memphis metropolitan area and had addresses which were successfully geocoded (Supplementary Figure F2), 220 (27.2%) patients were identified to be from high- (n = 126) or low-risk (n = 94) community-acquired pneumonia areas. Community-acquired pneumonia in Memphis metropolitan area had a non-homogenous geospatial pattern. PM2.5 was associated with residence in high-risk areas for community-acquired pneumonia. In addition, children with private insurance and bacterial, as opposed to viral, etiology of infection had a decreased risk of residence in a high-risk area for community-acquired pneumonia. The results from this paper suggest that environmental exposures as well as social risk factors are associated with childhood pneumonia.

Abstract
RESUMO O objetivo deste artigo foi avaliar o efeito do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB) no acesso e na qualidade da Atenção Básica. As internações por condições sensíveis à Atenção Básica foram utilizadas como variável dependente e indicador indireto da qualidade e do acesso a esse nível de atenção. Utilizou-se o método quantitativo de estudo, tendo como unidade de análise todos os municípios brasileiros. O estudo se dividiu em duas fases: na primeira, foi realizada uma análise descritiva exploratória em série temporal sobre os municípios brasileiros, abrangendo o período de 2010 a 2014; e a segunda fase se caracterizou por avaliar o efeito do Programa, durante o mesmo período, no acesso e na qualidade da Atenção Básica, por meio da técnica estatística de regressão com dados de contagem. Os resultados, analisados por região, apontaram que o Programa está apresentando um efeito significativo na qualidade e no acesso da Atenção Básica, principalmente na região Nordeste. Este artigo surge como um importante informativo sobre as políticas de saúde no Brasil e, também, como um meio de instrumentalizar os gestores e os diversos atores envolvidos no desenvolvimento e discussão de um dos principais programas da Atenção Básica.

Abstract
BACKGROUND Children with neurologic impairment (NI) are commonly hospitalized with acute respiratory infections (ARI). These children frequently require respiratory support at baseline and are often discharged before return to respiratory baseline. OBJECTIVE To determine if discharge before return to respiratory baseline is associated with reutilization among children with NI hospitalized with ARI. METHODS This single-center retrospective cohort study included children with NI aged 1 to 18 years hospitalized with ARI who required increased respiratory support between January 2010 and September 2015. The primary exposure was discharge before return to respiratory baseline. The primary outcome was 30-day hospital reutilization. A generalized estimating equation was used to examine the association between exposure and outcome while accounting for within-patient clustering and patient-level clinical complexity and illness severity. RESULTS In the 632 hospitalizations experienced by 366 children, children were discharged before return to respiratory baseline in 30.4% of hospitalizations. Compared with those hospitalizations in which children were discharged at baseline, hospitalizations with a discharge before return to respiratory baseline were more likely to be for privately insured, technology-dependent children with respiratory comorbidities. Compared with discharges at respiratory baseline, discharges with increased respiratory support had no difference in 30-day reutilization (32.8% vs 31.8%; P = .81; adjusted OR 0.80, 95% CI 0.51-1.26). CONCLUSIONS Among children with NI hospitalized with ARI, discharge before return to respiratory baseline was common, but it was not associated with hospital reutilization. Return to respiratory baseline may not be a necessary component of discharge criteria in this population.

Individual and neighbourhood socioeconomic status increase risk of avoidable hospitalizations among Canadian adults: A retrospective cohort study of linked population health data.

Abstract
INTRODUCTION Avoidable hospitalizations refer to acute care use for conditions that should normally be managed in primary care settings. Lower socioeconomic status that is often measured using area-based indicators (e.g. median household income) has been shown to increase risk of avoidable hospitalizations. However, both area- and individual-level socioeconomic status can contribute to hospitalization risk, but previous data limitations have prevented separate analyses. Further, the joint effect of individual and neighbourhood socioeconomic status has not been established in the Canadian population. To address this, this study links individual-level household income and neighbourhood-level material deprivation data within a population-based Canadian cohort. OBJECTIVES To determine the individual and joint effect of individual-level household income and neighbourhood-level material deprivation on risk of hospitalization for a set of chronic ambulatory care sensitive conditions using linked health survey, hospital discharge, and census-derived data. METHODS A pooled cohort was created by linking sociodemographic and health information from eight cycles of the Canadian Community Health Survey (2000/2001 - 2010) to hospital discharge records and Canadian Marginalization Indices (2001, 2006) (N = 354,595). The primary outcome variable was risk of index hospitalization with a primary diagnosis of angina, asthma, congestive heart failure, chronic obstructive pulmonary disease, diabetes, epilepsy, or hypertension. The primary exposure variable was joint individual-level national household income quintile and neighbourhood-level material deprivation quintile. Relative risk (RR) was estimated by constructing modified Poisson regression models with robust error variance. RESULTS In fully adjusted models with income and deprivation considered separately, individuals in the lowest household income quintile and highest material deprivation quintile were at increased risk of hospitalization (Income RR: 1.82 (95% CI 1.56-2.13) Deprivation RR: 1.67 (1.44-1.95)). When income and deprivation were jointly considered, those with low individual income living in high deprivation neighbourhoods were at greatest risk of hospitalization (RR 1.83 (95% CI 1.63 - 2.05)). CONCLUSION Both individual income and neighbourhood deprivation separately and jointly increase risk of avoidable hospitalizations. Additional research is needed to understand their mechanisms of action. However, both levels should be considered when designing effective policies and interventions to reduce avoidable hospitalizations.

Abstract
Hospitalizations for certain chronic conditions are considered avoidable for adult Canadians given effective and timely primary care management. Individual-level risk factors such as income and health behaviours are not routinely collected in most hospital databases and as a result, are largely uncharacterized for avoidable hospitalization at the national level. The aim of this study was to identify and describe demographic, socioeconomic, and health behavioural risk factors for avoidable hospitalizations in Canada using linked data. A national retrospective cohort study was conducted by pooling eight cycles of the Canadian Community Health Survey (2000/2001-2011) and linking to hospitalization records in the Discharge Abstract Database (1999/2000–2012/2013). Respondents who were younger than 18 years and older than 74 years of age, residing in Quebec, or pregnant at baseline were excluded yielding a final cohort of 389,065 individuals. The primary outcome measure was time-to index avoidable hospitalization. Sex-stratified Cox proportional hazard models were constructed to determine effect sizes adjusted for various factors and their associated 95% confidence intervals. Demographics, socioeconomic status, and health behaviours are associated with risk of avoidable hospitalizations in males and females. In fully adjusted models, health behavioural variables had the largest effect sizes including heavy smoking (Male HR 2.65 (95% CI 2.17–3.23); Female HR 3.41 (2.81–4.13)) and being underweight (Male HR 1.98 (1.14–3.43); Female HR 2.78 (1.61–4.81)). Immigrant status was protective in both sexes (Male HR 0.83 (0.69–0.98); (Female HR 0.69 (0.57–0.84)). Adjustment for behavioural and clinical variables attenuated the effect of individual-level socioeconomic status. This study identified several risk factors for time-to-avoidable hospitalizations by sex, using the largest national database of linked health survey and hospitalization records. The larger effect sizes of several modifiable risk factors highlights the importance of prevention in addressing avoidable hospitalizations in Canada.

Abstract
AIM We investigated socio-economic and geographical determinants of hospital care for viral gastroenteritis in young children. METHOD This is a register-based study in a national birth cohort of 752 078 children 0-5 years of age in Sweden during 2006-2012. Hazard ratios (HR) of time to first admission and first episode of outpatient emergency department (ED) care with a diagnosis of viral gastroenteritis were estimated with Cox regression. RESULTS The adjusted HRs for hospital admission with a diagnosis of viral gastroenteritis were increased when the mother was below 25 years at the birth of the child, 1.30 (95% CI: 1.24-1.35), had a short (<=9 years) education, 1.18 (95% CI: 1.12-1.23), a psychiatric disorder, 1.34 (95% CI: 1.30-1.39), and/or when parents were born outside Europe, 1.23 (95% CI: 1.18-1.29). In contrast, the disposable income of the family was only marginally associated with such hospital admissions. The pattern of HRs for outpatient ED hospital care was similar. Hospital care incidences for viral gastroenteritis differed considerably between Swedish counties. CONCLUSION Parental indicators associated with a lower level of health literacy increase the risk for hospital care due to gastroenteritis in young children. Information about oral rehydration should be provided in ways that are accessible to these parents.

Abstract
This study aimed to assess the effect of the expansion of the Family Health Strategy (FHS) on hospitalizations for primary care sensitive conditions (PCSCs) in children under one year of age. This was a longitudinal ecological study with the use of panel data, for which the analytical units were the 417 municipalities (counties) in Bahia State, Brazil, from 2000 to 2012. Data were obtained from the official health information systems. The hospitalization rate for PCSCs was the outcome and FHS coverage was the principal exposure. The co-variables referred to demographic and socioeconomic characteristics and the local availability of pediatric beds. Bivariate and multivariate panel data analyses were performed, with negative binomial response and fixed effects models, using crude and adjusted relative risk (RR) as the measure of association, with the respective confidence intervals. To control for trend effect, the models were adjusted for time. From 2000 to 2012, 248,944 hospitalizations for PCSCs were recorded in children under one year, and the median municipal rate of hospitalizations for PCSCs decreased by 52.5% during the period, ranging from 96.9 to 46.0 avoidable hospitalizations per 1,000 live births. After adjusting the model, the reduction in avoidable hospitalizations was maintained at the different FHS coverage levels. This study demonstrated the effects of the consolidation of the FHS on hospitalizations for PCSCs in infants, which indicates the importance of strengthening primary care measures in order to offer case-resolving care during the first contact with the health system and avoid unnecessary hospitalizations.

Abstract
BACKGROUND Physician turnover, involving physicians' leaving clinical practice in a specific area, may disrupt continuity of care, leading to poorer health outcomes and greater use of health care services. The purpose of this study was to investigate the relation between family physician retention and avoidable hospital admission for ambulatory-care-sensitive conditions. METHODS We conducted a population-based cross-sectional study using provincial health administrative data for residents of Newfoundland and Labrador who held a provincial health card between 2001 and 2009. Five-year family physician retention was calculated by regional economic zone, and residents within economic zones were grouped into tertiles based on physician retention level. We compared hospital admission for ambulatory-care-sensitive conditions among tertiles while adjusting for covariates. RESULTS For 475 691 residents of the province, there was a negative relation between physician retention and hospital admission for ambulatory-care-sensitive conditions: residents of areas with moderate or low physician retention had admission rates that were 16.5% (95% confidence interval [CI) 12.6%-20.4%) and 19.9% (95% CI 15.2%-24.7%) higher, respectively, compared to areas with high retention. No relation was found when analysis was limited to those aged 65 years or more. INTERPRETATION The findings suggest that high physician retention is associated with lower rates of hospital admission for ambulatory-care-sensitive conditions even after control for other factors. This is consistent with our hypothesis that physician turnover acts to disrupt continuity of care, resulting in higher admission rates.

Roos LL, Dragan R, Schroth RJ. Pediatric ambulatory care sensitive conditions: Birth cohorts and the socio-economic gradient. Canadian Journal of Public Health 2017; 108:e257-e264. [PMID: 28910247 DOI: 10.17269/cjph.108.5935] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 10/24/2016] [Revised: 05/17/2017] [Accepted: 03/03/2017] [Indexed: 11/17/2022]
Abstract
OBJECTIVES This study examines the socio-economic gradient in utilization and the risk factors associated with hospitalization for four pediatric ambulatory care sensitive conditions (dental conditions, asthma, gastroenteritis, and bacterial pneumonia). Dental conditions, where much care is provided by dentists and insurance coverage varies among different population segments, present special issues. METHODS A population registry, provider registry, physician ambulatory claims, and hospital discharge abstracts from 28 398 children born in 2003-2006 in urban centres in Manitoba, Canada were the main data sources. Physician visits and hospitalizations were compared across neighbourhood income groupings using rank correlations and logistic regressions. RESULTS Very strong relationships between neighbourhood income and utilization were highlighted. Additional variables - family on income assistance, mother's age at first birth, breastfeeding - helped predict the probability of hospitalization. Despite the complete insurance coverage (including visits to dentists and physicians and for hospitalizations) provided, receiving income assistance was associated with higher probabilities of hospitalization. CONCLUSIONS We found a socio-economic gradient in utilization for pediatric ambulatory care sensitive conditions, with higher rates of ambulatory visits and hospitalizations in the poorest neighbourhoods. Insurance coverage which varies between different segments of the population complicates matters. Providing funding for dental care for Manitobans on income assistance has not prevented physician visits or intensive treatment in high-cost facilities, specifically treatment under general anesthesia. When services from one type of provider (dentist) are not universally insured but those from another type (physician) are, using rates of hospitalization to indicate problems in the organization of care seems particularly difficult.

Abstract
Background Approximately 13% of Canadian mothers report difficulty accessing health care for their infants, yet little is known about the factors associated with difficulty. Therefore, we examined factors associated with difficulty accessing non-routine health care for Canadian infants, from birth to 14 months of age, as reported by their mothers. Methods Data was drawn from the Maternity Experiences Survey (MES), a cross-sectional, nationally representative survey of mothers who gave birth between November 2005 and May 2006, aged 15 years or older, and lived with their infants at the time of survey administration. A multivariable logistic regression analysis was conducted to determine factors associated with reporting difficulty, with difficulty defined as a mother reporting it being somewhat or very difficult to access a health care provider. Results Analysis of 2832 mothers who reported needing to access a health care provider for their infant for a non-routine visit found that 13% reported difficulty accessing a provider. Factors associated with reporting difficulty were: residing in Quebec (aOR 1.89, 95% CI: 1.31–2.73), being an immigrant (aOR 1.58, 95% CI: 1.10–2.27), mistimed pregnancy (aOR 1.44, 95% CI: 1.05–1.98), low level of social support (aOR 1.69, 95% CI: 1.05–2.73), good health (aOR 1.88, 95% CI: 1.43–2.47), postpartum depression symptoms (aOR 1.55, 95% CI: 1.02–2.37) and a self-reported ‘too-short’ postpartum hospital stay (aOR 1.69, 95% CI: 1.21–2.35). Additionally, accessing care for an infant with a birth weight of 2500 g or more (aOR 2.43, 95% CI: 1.02–5.82), was associated with reporting difficulty. Household income, mothers’ level of education, marital status, Aboriginal ethnicity, and size of community of residence were not associated with difficulty accessing care. Conclusions Ease of health care access for Canadian infants is not equal, suggesting that efforts to improve access should be tailored to groups facing increased difficulties.

Child Social Exclusion Risk and Child Health Outcomes in Australia. PLoS One 2016; 11:e0154536.

Abstract
Introduction This paper studies the relationship between the risk of child social exclusion, as measured by the Child Social Exclusion (CSE) index and its individual domains, and child health outcomes at the small area level in Australia. The CSE index is Australia’s only national small-area index of the risk of child social exclusion. It includes five domains that capture different components of social exclusion: socio-economic background, education, connectedness, housing and health services. Methods The paper used data from the National Centre for Social and Economic Modelling (NATSEM), University of Canberra for the CSE Index and its domains and two key Australian Institute of Health and Welfare (AIHW) data sources for the health outcome measures: the National Hospital Morbidity Database and the National Mortality Database. Results The results show positive associations between rates of both of the negative health outcomes: potentially preventable hospitalisations (PPH) and avoidable deaths, and the overall risk of child social exclusion as well as with the index domains. This analysis at the small-area level can be used to identify and study areas with unexpectedly good or bad health outcomes relative to their estimated risk of child social exclusion. We show that children’s health outcomes are worse in remote parts of Australia than what would be expected solely based on the CSE index. Conclusions The results of this study suggest that developing composite indices of the risk of child social exclusion can provide valuable guidance for local interventions and programs aimed at improving children’s health outcomes. They also indicate the importance of taking a small-area approach when conducting geographic modelling of disadvantage.

Abstract
Introduction Ambulatory Care Sensitive Conditions (ACSC) are conditions for which hospitalisation is thought to be avoidable with the use of effective preventive care and early disease management. The objective of this study was to estimate the rate of avoidable hospitalisations in children younger than 24 months of age participating in a Brazilian national representative survey and to identify the risk factors for such hospitalisations. Methods We analysed data from a cross-sectional study of 1901 children from the 2006 Brazilian National Demographic Health Survey of Women and Children (NDHS). The children’s socioeconomic, biological and maternal characteristics, nutritional status, and access to healthcare were tested; variables with p < 0.20 were selected to fit a Poisson regression. Results The prevalence of avoidable hospitalisation was 11.8 % (95 % Confidence Interval [CI], 9.0, 15.2); the prevalence was higher in the Southeast (40.1 %) and Northwest (21.7 %) macro-regions. The multivariate model identified five risk factors for avoidable hospitalisation: male gender (Prevalence Ratio [PR] = 1.48, p = 0.004), low socioeconomic level (PR = 1.51, p = 0.005), children from mothers younger than 20 years of age (PR = 1.41, p = 0.031), not breastfed within the first hour of life (PR = 1.29, p = 0.034), and neonatal hospitalisation (PR = 1.66, p = 0.043). Conclusions To decrease the costs associated with avoidable hospitalisations, health managers and professionals should focus their efforts on providing effective primary healthcare to families of low socioeconomic levels, particularly prenatal and paediatric care, as well as encouraging breastfeeding and supporting young mothers. Strategies to improve children’s health by controlling such hospitalisations in Brazil should consider all residence areas and geopolitical macro-regions.

Abstract
BACKGROUND Asthma, one of the most common chronic respiratory diseases, affects about 3 million Canadians. The objective of this study is to provide a comprehensive evaluation of the published literature that reports on the clinical, economic, and humanistic burden of asthma in Canada. METHODS A search of the PubMed, EMBASE, and EMCare databases was conducted to identify original research published between 2000 and 2011 on the burden of asthma in Canada. Controlled vocabulary with "asthma" as the main search concept was used. Searches were limited to articles written in English, involving human subjects and restricted to Canada. Articles were selected for inclusion based on predefined criteria like appropriate study design, disease state, and outcome measures. Key data elements, including year and type of research, number of study subjects, characteristics of study population, outcomes evaluated, results, and overall conclusions of the study, were abstracted and tabulated. RESULTS Thirty-three of the 570 articles identified by the clinical and economic burden literature searches and 14 of the 309 articles identified by the humanistic burden literature searches met the requirements for inclusion in this review. The included studies highlighted the significant clinical burden of asthma and show high rates of healthcare resource utilization among asthma patients (hospitalizations, ED, physician visits, and prescription medication use). The economic burden is also high, with direct costs ranging from an average annual cost of $366 to $647 per patient and a total annual population-level cost ranging from ~ $46 million in British Columbia to ~ $141 million in Ontario. Indirect costs due to time loss from work, productivity loss, and functional impairment increase the overall burden. Although there is limited research on the humanistic burden of asthma, studies show a high (31%-50%) prevalence of psychological distress and diminished QoL among asthma patients relative to subjects without asthma. CONCLUSIONS As new therapies for asthma become available, economic evaluations and assessment of clinical and humanistic burden will become increasingly important. This report provides a comprehensive resource for health technology assessment that will assist decision making on asthma treatment selection and management guidelines in Canada.

Abstract
OBJECTIVES To describe the demographic characteristics and identify the needs of a population attending an urban, low-income area, multicultural paediatric clinic. METHODS Surveys were distributed to caregivers of children zero to 16 years of age (n=299). RESULTS Of the children attending appointments, 55% were female and 51% were five years of age or younger. Of the caregivers, 29.5% were born outside of Canada and 25% reported that their primary spoken language was not English. Sixty-six per cent of families had been living in Edmonton for more than three years, with two-thirds of respondents living in Edmonton's second-lowest average household income region. Seventy-six per cent of respondents lived in households with four or more persons. CONCLUSIONS Challenges facing individuals attending an urban, low-income area, paediatric clinic include language barriers, lower household income and larger family size. Immigrants living outside of major Canadian cities are under-represented and may have different needs compared with their counterparts in 'gateway' cities. More studies are needed to determine their needs, and will ultimately lead to the provision of culturally competent care.

Abstract
BACKGROUND Hospitalisations for ambulatory care-sensitive (ACS) conditions are used as an indicator of access to, and the quality of, primary care. The objective was to identify factors associated with hospitalisations for ACS conditions among adults with an intellectual disability (ID) in the context of a publicly insured healthcare system. METHODS This study examined adults with an ID living in a Canadian province between 1999 and 2003 identified from administrative databases. Using 5 years of data for the study population, characteristics of persons hospitalised or not hospitalised for ACS conditions were compared. Using a conceptual model, independent variables were selected and an analysis performed to identify which were associated with hospitalisations for ACS conditions. The correlated nature of the observations was accounted for statistically. RESULTS Living in a rural area [odds ratio (OR) 1.3; 95% confidence intervals (CI) = 1.0, 1.8], living in an area with a high proportion of First Nations people (OR 2.3; 95% CI = 1.3, 4.1), and experiencing higher levels of comorbidity (OR 25.2; 95% CI = 11.9, 53.0) were all associated with a higher likelihood of being hospitalised for an ACS condition. Residing in higher income areas had a protective effect (OR 0.56; 95% CI = 0.37, 0.85). None of the health service resource variables showed statistically significant associations. CONCLUSIONS Persons with an ID experience inequity in hospitalisations for ACS conditions according to rurality, income and proportion who are First Nations in a geographic area. This suggests that addressing the socio-economic problems of poorer areas and specifically areas densely populated by First Nations people may have an impact on the number of hospitalisations for ACS conditions. Study strengths and limitations and areas for potential future research are discussed.

Abstract
Background Ambulatory Care Sensitive Conditions (ACSCs) are those for which hospitalisation is thought to be avoidable with the application of preventive care and early disease management, usually delivered in a primary care setting. ACSCs are used extensively as indicators of accessibility and effectiveness of primary health care. We examined the association between patient characteristics and hospitalisation for ACSCs in the adult and paediatric population in Victoria, Australia, 2003/04. Methods Hospital admissions data were merged with two area-level socioeconomic indexes: Index of Socio-Economic Disadvantage (IRSED) and Accessibility/Remoteness Index of Australia (ARIA). Univariate and multiple logistic regressions were performed for both adult (age 18+ years) and paediatric (age <18 years) groups, reporting odds ratios (OR) and 95% confidence intervals (CI) for a number of predictors of ACSCs admissions compared to non-ACSCs admissions. Results Predictors were much more strongly associated with ACSCs admissions compared to non-ACSCs admissions in the adult group than for the paediatric group with the exception of rurality. Significant adjusted ORs in the adult group were 1.06, 1.15, 1.13, 1.06 and 1.11 for sex, rurality, age, IRSED and ARIA variables, and 1.34, 1.04 and 1.09 in the paediatric group for rurality, IRSED and ARIA, respectively. Conclusions Disadvantaged paediatric and adult population experience more need of hospital care for ACSCs. Access barriers to primary care are plausible causes for the observed disparities. Understanding the characteristics of individuals experiencing access barriers to primary care will be useful for developing targeted interventions meeting the unique ambulatory needs of the population.

Abstract
There is a persistent relationship between socioeconomic status and health that appears to have its roots in childhood. Not only do children in families with lower income and with mothers with lower levels of education have worse health on average than those with greater socioeconomic advantage, but also the gradient appears to steepen with age. This study contributes to the literature on the relationship between socioeconomic status and child health by testing the hypothesis that the increasing effect of family income on children's health with age relates to the children's use of health care services. It also investigates the role of specific health conditions, injuries or maternal health in explaining the steepening gradient. Drawing on a nationally representative survey from Canada, the National Longitudinal Survey of Children and Youth from the period 1994/95-2008/09, this study provides further evidence of a steepening socioeconomic gradient in child health with age. It finds that accounting for health care use does not explain the steepening gradient and that the protective effect of income appears to be greater for those who had contact with the health system, in particular with regard to physician care and prescription drug use.

Abstract
OBJECTIVES How to provide effective and efficient care to the burgeoning and aging populations of the major cities of low- and middle-income countries constitutes one of the principle public health issues of our times. We evaluated the Family Health Strategy, the Brazilian national health system's public approach to primary health care, in the major city of Belo Horizonte, describing trends and factors associated with hospitalizations for primary care sensitive conditions following the implementation of 506 family health teams, most of which were established in 2002. METHODS We conducted an ecological study covering 2003 to 2006, using mixed models to investigate time trends in public system hospitalizations as well as their association with social vulnerability and primary care team characteristics. RESULTS Sensitive conditions accounted for 115,340 (26.4%) hospitalizations. Over the 4-year period, hospitalizations for sensitive conditions declined by 17.9%, vs only 8.3% for non-sensitive ones (P<0.001). Hospitalization for sensitive conditions declined 22% for women in areas of high social vulnerability vs 9% for women in areas of low vulnerability (P<0.001); for men, 17% vs 10% (P=0.11). CONCLUSIONS Though the ecologic nature of our study limits the confidence with which conclusions can be affirmed, the Family Health Strategy appears to have contributed to a major reduction in hospitalizations due to primary care sensitive conditions in this large Brazilian metropolis, while at the same time promoting greater health equity.

Abstract
OBJECTIVE To examine healthcare utilization according to family income in children with inflammatory bowel disease (IBD). STUDY DESIGN A population-based cohort of children aged <18 years diagnosed with IBD between 1994 and 2004 was followed using health administrative data. Multivariate models were used to test the association between mean neighborhood income quintile and physician and emergency department visits, hospitalizations, or surgeries. RESULTS Compared with children from higher-income neighborhoods, children from low-income neighborhoods were more likely to be hospitalized at least once (hazard ratio, 1.17; 95% CI, 1.05 to 1.30) or to visit the emergency department (hazard ratio, 1.21; 95% CI, 1.09 to 1.35), and had more IBD-related physician visits (OR, 3.73; 95% CI, 1.05 to 13.27). Children from low-income neighborhoods with Crohn's disease (but not those with ulcerative colitis) were more likely to undergo intra-abdominal surgery within 3 years of diagnosis (OR, 1.22; 95% CI, 1.01 to 1.49), especially when diagnosed after 2000 (OR, 1.79; 95% CI, 1.27 to 2.53). CONCLUSIONS Lower income was associated with a higher rate of health services utilization in children with IBD and with a greater risk of surgery in children with Crohn's disease.

[PMID: 20967840 DOI: 10.1002/ppul.21368] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2010] [Revised: 08/23/2010] [Accepted: 08/23/2010] [Indexed: 11/10/2022]
Abstract
BACKGROUND Socioeconomic status (SES) is a strong predictor of outcomes in cystic fibrosis (CF); however, there are no published studies evaluating this relationship in Canadians with CF. The objective of this study was to assess the effect of SES on annual hospitalization rates in a large cohort of pediatric and adult CF subjects under a universal health care system. METHODS A population-based longitudinal study was completed in Ontario from 1993 to 2002 using a comprehensive CF registry containing patient-level data, linked to provincial health care administrative databases. Income quintiles were derived at the neighborhood level using postal code information and Statistics Canada census data. The effect of income quintile on the annual hospitalization rate for respiratory-related illness was estimated by Poisson regression using generalized estimating equations, and was expressed as a rate ratio (RR) and 95% confidence interval (CI). The analysis was adjusted for age, sex, lung function, nutritional status, the presence of diabetes, area of residence, and distance between the subject's residence and the reporting CF centre. RESULTS A total of 1,174 participants over the age of 6 years contributed 8,444 patient-years of data. No statistically significant differences in annual hospitalization rates for respiratory-related causes were found between the lowest and highest income quintiles (adjusted RR 1.17 [95% CI 0.96-1.43]). The effect of income quintile remained non-significant across a majority of markers of CF disease severity and across a range of subgroups. CONCLUSIONS After adjusting for important covariates, no SES-disparities in hospitalization rates were found in a large Canadian pediatric and adult CF cohort. It may be the distinctive combination of universal health care, a national network of specialty CF clinics, and drug and travel coverage available in Ontario that results in similar hospitalization rates regardless of SES.

Abstract
OBJECTIVES To describe the relationship of primary care physician (PCP) supply for children and measures of health care access, use, and outcomes. METHODS We conducted a population-based, cross-sectional study of all Ontario children from 2003 to 2005. We used health administrative data to calculate county-level supply (full-time equivalents [FTEs]) of PCPs. We modeled the relationship of supply to (1) recommended primary care visits, (2) emergency department (ED) use, and (3) ambulatory care-sensitive condition admissions and adjusted for neighborhood income. We used population-based surveys to describe access. RESULTS The county-level PCP supply ranged from 1720 to 4720 children per FTE. Of the children, 45.4% live in the highest-supply areas (<2000 children per FTE) and 8% in the lowest-supply areas (>3000 children per FTE). Compared with high-supply counties, the lowest had significantly lower rates of primary care visits (2716 vs 7490 per 1000) and higher proportions of newborns without early follow-care (58.2% vs 14.5%). Low-supply areas had higher rates of ED visits (440 vs 179 per 1000) and admissions. A stepwise gradient existed for every decrease in supply for most measures. Self-reported access barriers were most evident in areas with >3500 children per FTE (32.8% without a physician). CONCLUSIONS Under universal insurance there are differences in access to, and outcomes of, primary care related to local physician supply after controlling for neighborhood income. The most pronounced effect is on primary and ED care use, but there are implications for acute and chronic disease control. Physician distribution is a critical issue to address in policies to improve access to care.

Abstract
OBJECTIVES The goals were (1) to describe rates of diabetes mellitus (DM)-related hospitalizations and retinopathy screening before and after transition to adult care and (2) to test whether different methods of transfer of care were associated with improved outcomes. METHODS In a retrospective cohort study, we included 1507 young adults with DM of >or=5-year duration and tracked these patients until 20 years of age. RESULTS DM-related hospitalization rates increased from 7.6 to 9.5 cases per 100 patient-years in the 2 years after transition to adult care (P = .03). Previous DM-related hospitalizations, lower income, female gender, and living in areas with low physician supply were associated with higher admission rates. With controlling for all other factors, individuals who were transferred to a new allied health care team with no change in physician were 23% less likely (relative risk: 0.23 [95% confidence interval: 0.05-0.79]) to be hospitalized after the transition than were those transferred to a new physician with either a new or no allied health care team. The rates of eye examinations were stable across the transition to adult care (72% vs 70%; P = .06). Female patients, patients with higher income, and patients with previous eye care were more likely to have an eye care visit after transfer. CONCLUSIONS During the transition to adult health care, there is increased risk of DM-related hospitalizations, although this may be attenuated in youths for whom there is physician continuity. Eye care visits were not related to transition; however, rates were below evidence-based guideline recommendations.

Abstract
PURPOSE OF REVIEW Despite overall improvements in asthma care through an increasing evidence base, disparities in outcomes of children of ethnic minorities and low socioeconomic status are well documented across healthcare systems. New interventions to reduce gaps in outcomes among these children are continually being evaluated. This article reviews the most relevant and influential recent studies. RECENT FINDINGS A number of interventions aimed at vulnerable children with asthma have been successful. Most of these include a component of education and self-management. There is some evidence that culturally competent care produces improved outcomes, whereas stronger evidence exists for multifaceted programs and community health workers providing home visits for education and environmental allergen reduction. Targeting children and families through school-based programs may be an effective outreach strategy. Use of novel technologies such as educational messages on MP3 players shows promise in reaching at-risk adolescents. SUMMARY There are promising strategies proven to significantly decrease disparities in asthma among vulnerable children. Further research must be performed to elucidate the interventions that produce the greatest impact on asthma-related outcomes while being feasible, sustainable, and cost-effective.
