The effects of regular source of care and health need on medical care use among rural adolescents

Usual source of healthcare and use of sexual and reproductive health services by female sex workers in Brazil

The fact of having a usual source of care can improve access to health services and preventive activities. The article aimed to estimate the proportion of factors associated with usual source of care among female sex workers. This was a socio-behavioral survey with 4,328 female sex workers, ≥ 18 years, in 12 Brazilian cities. Female sex workers were recruited by the respondent-driven sampling method (RDS). A descriptive profile was performed of the female sex workers who had usual source of care and the association was analyzed between usual source of care and indicators of access to HIV prevention and reproductive health. As effect measure, the study used adjusted odds ratio (OR) in a logistic regression model. The data were weighted by the RDS-II estimator. 71.5% of the female sex workers reported having a usual source of care, and of these, 54.3% cited primary healthcare (PHC) as their main usual source of care. Among female sex workers 18-24 years of age, there was an association between usual source of care and having a Pap smear test (OR = 2.27; 95%CI: 1.66-3.12), seven or more prenatal visits (OR = 2.56; 95%CI: 1.30-5.03), and the use of a contraceptive method (OR = 1.64; 95%CI: 1.09-2.46). Among female sex workers ≥ 25 years, there was an association between usual source of care and attending talks on sexually transmitted infections (STIs) (OR = 1.45; 95%CI: 1.12-1.89), prior knowledge of post-exposure prophylaxis (OR = 1.32; 95%CI: 1.02-1.71), and history of Pap smear test (OR = 1.92; 95%CI: 1.54-2.40). The study's results showed that female sex workers have PHC as their main usual source of care. usual source of care can also positively impact care and activities in reproductive health and prevention of HIV and STIs in this population group.

Primary Care Provider Encounter Cadence and HbA1c Control in Older Patients With Diabetes

INTRODUCTION

Primary care provider encounters are associated with health and well-being; however, limited evidence guides optimal primary care provider rate of visit, referred to as encounter cadence. This study measures associations between primary care provider encounter cadence and diabetes outcomes among individuals newly diagnosed with type 2 diabetes mellitus.

METHODS

In this retrospective cohort study, 7,106 people enrolled in Medicare Advantage and newly diagnosed with type 2 diabetes mellitus between July 1, 2012 and June 30, 2013 were identified and followed for 36 months. Two methods measured primary care provider encounter cadence: total primary care provider encounters (frequency) and quarters with primary care provider encounter (regularity). Logistic regression measured relationships between primary care provider encounter cadence and non-insulin diabetes medication adherence, HbA1c control, emergency department visits, and inpatient admissions. Non-insulin diabetes medication adherence was defined according to the National Committee for Quality Assurance, Healthcare Effectiveness Data and Information Set specifications and measured using healthcare claims data. Post-hoc models examined adherence and diabetes control among those nonadherent (n=5,212) and with noncontrolled HbA1c (n=326) during the encounter/cadence period. Data were extracted and analyzed in 2017.

RESULTS

Adjusted models indicated that both frequency (AOR=1.08, 95% CI=1.06, 1.10) and regularity (AOR=1.18, 95% CI=1.13, 1.22) of primary care provider encounters were associated with increased odds of adherence. Post-hoc analyses indicated that more frequent (AOR=1.12, 95% CI=1.10, 1.15) and regular (AOR=1.27, 95% CI=1.22, 1.33) primary care provider encounters were associated significantly with adherence and were associated directionally with HbA1c control.

CONCLUSIONS

More frequent and regular primary care provider encounters are associated with an increased likelihood of non-insulin diabetes medication adherence. These findings contribute to data needed to establish evidence-based guidelines for primary care provider encounter cadence for those newly diagnosed with type 2 diabetes mellitus.

The role of spatially-derived access-to-care characteristics in melanoma prevention and control in Los Angeles county

Among 10,068 incident cases of invasive melanoma, we examined the effects of patient characteristics and access-to-care on the risk of advanced melanoma. Access-to-care was defined in terms of census tract-level sociodemographics, health insurance, cost of dermatological services and appointment wait-times, clinic density and travel distance. Public health insurance and education level were the strongest predictors of advanced melanomas but were modified by race/ethnicity and poverty: Hispanic whites and high-poverty neighborhoods were worse off than non-Hispanic whites and low-poverty neighborhoods. Targeting high-risk, underserved Hispanics and high-poverty neighborhoods (easily identified from existing data) for early melanoma detection may be a cost-efficient strategy to reduce melanoma mortality.

Outcomes for Children with Chronic Conditions Associated with Parent- and Provider-reported Measures of the Medical Home

PURPOSE

Assess relationships between having a patient-centered medical home (PCMH) and health care utilization among low-income children with chronic conditions using parent and practice perspectives.

METHODS

We analyzed data from 240 publicly insured children with chronic conditions. Parents completed surveys assessing PCMH access and their child's primary care practice completed the Medical Home Index (MHI) self-assessment. Multivariate negative binomial analyses were conducted to investigate relationships between PCMH and service use.

RESULTS

Parent-report of a usual source of care was associated with lower rates of emergency care (ED) encounters and hospitalizations. Practice report of higher organizational capacity (e.g., communication, staff education) was associated with lower rates of ED visits and hospitalizations. Parent report of a PCMH was positively associated with practice MHI score.

CONCLUSIONS

Among low-income children with chronic conditions, having a usual source of care and higher quality organizational capacity were associated with lower rates of ED visits and hospitalizations.

Quantifying the Health Benefits of Primary Care Physician Supply in the United States

This analysis addresses the question, Would increasing the number of primary care physicians improve health outcomes in the United States? A search of the PubMed database for articles containing “primary care physician supply” or “primary care supply” in the title, published between 1985 and 2005, identified 17 studies, and 10 met all inclusion criteria. Results were reanalyzed to assess primary care effect size and the predicted effect on health outcomes of a one-unit increase in primary care physicians per 10,000 population. Primary care physician supply was associated with improved health outcomes, including all-cause, cancer, heart disease, stroke, and infant mortality; low birth weight; life expectancy; and self-rated health. This relationship held regardless of the year (1980–1995) or level of analysis (state, county, metropolitan statistical area (MSA), and non-MSA levels). Pooled results for all-cause mortality suggest that an increase of one primary care physician per 10,000 population was associated with an average mortality reduction of 5.3 percent, or 49 per 100,000 per year.

Trajectories of Health and Behavioral Health Services Use among Community Corrections-Involved Rural Adults

This article seeks to establish time-based trajectories of health and behavioral health services utilization for community corrections-involved (CCI) adults and to examine demographic and clinical correlates associated with these trajectories. To accomplish this aim, the authors applied a latent class growth analysis (LCGA) to services use data from a sample of rural CCI adults who reported their medical, mental health, and substance use treatment utilization behavior every 60 days for 1.5 years. LCGA established 1.5-year trajectories and demographic correlates of health services among rural CCI adults. For medical services, three classes emerged (stable-low users, 13%; stable-intermediate users, 40%; and stable-high users, 47%). For mental health and substance use services, three classes emerged (stable-low, 69% and 61%, respectively; low-baseline-increase, 10% and 12%, respectively; high-baseline decline, 21% and 28%, respectively). Employment, gender, medication usage, and depression severity predicted membership across all services. Results underscore the importance of social workers and other community services providers aligning health services access with the needs of the CCI population, and highlight CCI adults as being at risk of underservice in critical prevention and intervention domains.

Characteristics of ambulatory care visits to family medicine specialists in Taiwan: a nationwide analysis

Although family medicine (FM) is the most commonly practiced specialty among all the medical specialties, its practice patterns have seldom been analyzed. Looking at data from Taiwan's National Health Insurance Research Database, the current study analyzed ambulatory visits to FM specialists nationwide. From a sample dataset that randomly sampled one out of every 500 cases among a total of 309,880,000 visits in 2012, it was found that 18.8% (n = 116, 551) of the 619,760 visits in the dataset were made to FM specialists. Most of the FM services were performed by male FM physicians. Elderly patients above 80 years of age accounted for only 7.1% of FM visits. The most frequent diagnoses (22.8%) were associated acute upper respiratory infections (including ICD 460, 465 and 466). Anti-histamine agents were prescribed in 25.6% of FM visits. Hypertension, diabetes and dyslipidemia were the causes of 20.7% of the ambulatory visits made to FM specialists of all types, while those conditions accounted for only 10.6% of visits to FM clinics. The study demonstrated the relatively low proportion of chronic diseases that was managed in FM clinics in Taiwan, and our detailed results could contribute to evidence-based discussions on healthcare policymaking and residency training.

Sex differences in suicides among children and youth: the potential impact of help-seeking behaviour

OBJECTIVE

To describe sex differences in health service use among children and youth who died by suicide.

METHOD

This is a retrospective study of children and youth (aged 10 to 25 years) living in Ontario who died by suicide between April 1, 2003, and December 31, 2007. Coroner records were individually linked to outpatient physician visit, emergency department (ED) presentation, and inpatient stay administrative health care records for 724 people (192 girls and 532 boys). Only 77 (10.6%) were aged 10 to 15 years. The health services types used, number of contacts made, and the last contact were compared in boys and girls.

RESULTS

About 80% of subjects had contact with the health care system in the year before their death, typically to an outpatient physician and (or) the ED. However, not all were seen for mental health reasons. Girls had more outpatient physician and ED contact than boys and closer in time to their death. Further, girls were more likely than boys to have contact in more than one setting. Still, boys and girls did not differ in their use of an outpatient psychiatrist, some ED presentations, and in the nature and number of inpatient stays.

CONCLUSIONS

While most people were seen by an outpatient physician and (or) in the ED in the year before their death, not all received mental health care. Further research is needed to determine whether boys and girls who died by suicide differ from their peers in their health service use to guide preventive interventions.

Child maltreatment and repeat presentations to the emergency department for suicide-related behaviors

OBJECTIVES

To identify factors associated with repeat emergency department (ED) presentations for suicide-related behaviors (SRB) - hereafter referred to as repetition - among children/youth to aid secondary prevention initiatives. To compare rates of repetition in children/youth with substantiated maltreatment requiring removal from their parental home with their peers in the general population.

METHODS

A population-based (retrospective) cohort study was established for children/youth with a first ED SRB presentation at risk for repetition in the Province of Ontario, Canada between 1 January 2004 and 31 December 2008. Children/youth legally removed from their parental home because of substantiated maltreatment (n=179) and their population-based peers (n=6,305) were individually linked to administrative health care records over time to ascertain social, demographic, and clinical information and subsequent ED presentations for SRB during follow-up. These children/youth were described and their repetition-free probabilities over time compared. To identify factors associated with repetition we fit multivariable, recurrent event survival analysis models stratified by repetition and present unadjusted and adjusted hazard ratios (HRs) and 95% confidence intervals (CIs).

RESULTS

Children/youth with substantiated maltreatment (as noted) were two times more likely to have repetition than their peers after adjustments for social, demographic, and clinical factors (conditional on prior ED SRB presentations). A number of these factors were independently associated with repetition. No one factor distinguished between having a first and second repetition nor was more strongly associated with repetition than another.

CONCLUSIONS

The risk of repetition is higher in children with substantiated maltreatment (as noted) than their peers. No one factor stood out as predictive of repetition. Implications for secondary prevention initiatives include a non-selective approach, sensitive to family difficulties and the need to better contextualize repetition and harness data linkages.

Association of care in a medical home and health care utilization among children with sickle cell disease

OBJECTIVE

Sickle cell disease (SCD) is marked by high utilization of medical services. The aim of this study was to determine whether having a patient-centered medical home (PCMH) is associated with a reduction in emergency care (ED) utilization or hospitalizations among children with SCD.

METHODS

We collected and analyzed data from parents of 150 children, ages 1 to 17 years, who received care within a large children's hospital. The primary dependent variables were rates of parent-reported ED visits and hospitalizations. The principal independent variable was parent-reported experience with an overall PCMH or its four individual components (regular provider, comprehensive care, family-centered care, and coordinated care). Multivariate negative binomial regression, yielding incident rate ratios (IRR), was used for analysis.

RESULTS

Children who received comprehensive care had half the rate of ED visits (IRR 0.51, 95% confidence interval, 0.33-0.78) and nearly half the rate of hospitalizations (IRR 0.56, 95% confidence interval, 0.33-0.93) compared to children without comprehensive care. No other component of the PCMH was significantly associated with ED visits or hospitalizations. Children reported to have excellent/very good/good health status had lower odds of ED visits and hospitalizations compared to those reported to be in fair/poor condition.

CONCLUSIONS

Children with SCD reported to experience comprehensive care had lower rates of ED encounters and hospitalizations after controlling for demographics and health status. The overall findings highlight that the provision of comprehensive care--having a usual source of care and no problems with referrals--may provide a strategy for improving pediatric SCD care.

In search of attachment: a qualitative study of chronically ill women transitioning between family physicians in rural Ontario, Canada

Background

Most Canadians receive basic health services from a family physician and these physicians are particularly critical in the management of chronic disease. Canada, however, has an endemic shortage of family physicians. Physician shortages and turnover are particularly acute in rural regions, leaving their residents at risk of needing to transition between family physicians. The knowledge base about how patients manage transitioning in a climate of scarcity remains nascent. The purpose of this study is to explore the experience of transitioning for chronically ill, rurally situated Canadian women to provide insight into if and how the system supports transitioning patients and to identify opportunities for enhancing that support.

Methods

Chronically ill women managing rheumatic diseases residing in two rural counties in the province of Ontario were recruited to participate in face-to-face, semi-structured interviews. Interview transcripts were analysed thematically to identify emergent themes associated with the transitioning experience.

Results

Seventeen women participated in this study. Ten had experienced transitioning and four with long-standing family physicians anticipated doing so soon. The remaining three expressed concerns about transitioning. Thematic analysis revealed the presence of a transitioning trajectory with three phases. The detachment phase focused on activities related to the termination of a physician-patient relationship, including haphazard notification tactics and the absence of referrals to replacement physicians. For those unable to immediately find a new doctor, there was a phase of unattachment during which patients had to improvise ways to receive care from alternative providers or walk-in clinics. The final phase, attachment, was characterized by acceptance into the practice of a new family physician.

Conclusions

Participants often found transitioning challenging, largely due to perceived gaps in support from the health care system. Barriers to a smooth transition included inadequate notification procedures, lack of formal assistance finding new physicians, and unsatisfactory experiences seeking care during unattachment. The participants’ accounts reveal opportunities for a stronger system presence during transition and a need for further research into alternative models of primary care delivery.

How community members and health professionals conceptualize medical emergencies: implications for primary care promotion

Access to continuous care through a primary care provider is associated with improved health outcomes, but many communities rely on emergency departments (EDs) for both emergent and non-emergent health problems. This article describes one portion of a community-based participatory research project and investigates the type of education that might be needed as part of a larger intervention to encourage use of a local primary care clinic. In this article we examine how people who live in a low-income urban community and the healthcare workers who serve them conceptualize 'emergency medical condition'. We conducted forum and focus group discussions with 52 community members and individual interviews with 32 healthcare workers. Our findings indicate that while community members share a common general definition of what constitutes a medical emergency, they also desire better guidelines for how to assess health problems as requiring emergency versus primary care. Pain, uncertainty and anxiety tend to influence their choice to use EDs rather than availability of primary care. Implications for increasing primary care use are discussed.

Lessons learned from implementing the patient-centered medical home

The Patient-Centered Medical Home (PCMH) is a primary care model that provides coordinated and comprehensive care to patients to improve health outcomes. This paper addresses practical issues that arise when transitioning a traditional primary care practice into a PCMH recognized by the National Committee for Quality Assurance (NCQA). Individual organizations' experiences with this transition were gathered at a PCMH workshop in Alexandria, Virginia in June 2010. An analysis of their experiences has been used along with a literature review to reveal common challenges that must be addressed in ways that are responsive to the practice and patients' needs. These are: NCQA guidance, promoting provider buy-in, leveraging electronic medical records, changing office culture, and realigning workspace in the practice to accommodate services needed to carry out the intent of PCMH. The NCQA provides a set of standards for implementing the PCMH model, but these standards lack many specifics that will be relied on in location situations. While many researchers and providers have made critiques, we see this vagueness as allowing for greater flexibility in how a practice implements PCMH.

Understanding the Gap in Primary Care Access and Use Between Teens and Younger Children

Primary health care use among teenagers falls short of clinical recommendations and consistently lags behind that of younger children. Using the Medical Expenditure Panel Survey, the authors explore three explanations for this age-related gap: family composition, parental awareness of children’s health care needs, and the relative role of predisposing, enabling, and need-based factors for teens and younger children. Teenagers are 64% more likely to have no usual source of care and 25% more likely to have had no health care visit in the prior year relative to younger children. The gap narrows in families with children from both age-groups and among children with special health care needs. The largest disparity in primary care access exists between teens in families with no younger sibling(s) and younger children in families with no teen(s). A resolution to the age-related access gap will likely require understanding of, and intervention into, family-level determinants of poor access.

Child maltreatment and onset of emergency department presentations for suicide-related behaviors

OBJECTIVES

To determine whether the rates of a first presentation to the emergency department (ED) for suicide-related behavior (SRB) are higher among children/youth permanently removed from their parental home because of substantiated maltreatment than their peers. To describe the health care settings accessed by these children/youth before a first SRB presentation to help design preventive interventions.

METHODS

A population-based (retrospective) cohort of 12-17-year-olds in Ontario, Canada was established. Children/youth removed from their parental home because of the above noted maltreatment (n=4683) and their population-based peers (n=1,034,546) were individually linked to administrative health care records over time to ascertain health service use and subsequent ED presentations for SRB during follow-up. Person-time incidence rates were calculated and Cox regression models used to estimate adjusted hazard ratios (HR) and corresponding 95% confidence intervals (CI).

RESULTS

After controlling for demographic characteristics and prior health service use, maltreated children/youth were about five times more likely to have a first ED presentation for SRB compared to their peers, in both boys (HR: 5.13, 95% CI: 3.94, 6.68) and girls (HR: 5.36, 95% CI: 4.40, 6.54).

CONCLUSIONS

Children/youth permanently removed from their parental home because of substantiated child maltreatment are at an increased risk of a first presentation to the ED for SRB. The prevention of child maltreatment and its recurrence and the promotion of resilience after maltreatment has occurred are important avenues to study toward preventing ED SRB presentations in children/youth. Provider and system level linkages between care sectors may prevent the need for such presentations by providing ongoing environmental support.

Emergency department reliance among rural children in Medicaid in New York State

PURPOSE

This study examines variation in emergency department reliance (EDR) between rural and metro pediatric Medicaid patients in New York State for noninjury, nonpoisoning primary diagnoses and seeks to determine the relationship between receipt of preventive care and the likelihood of EDR.

METHODS

Rural/urban designations were based on Urban Influence Codes established by the United States Department of Agriculture (USDA). Healthcare Effectiveness Data and Information Set (HEDIS(®)) well-visit measures were calculated using 2008 Medicaid claims and encounter data. Well-child numerator status and location of residence variables were then entered as independent variables in multivariate logistic regression models. Models controlled for the effects of Medicaid financing system (fee-for-service vs managed care), Medicaid aid type, race/ethnicity, gender, and 2008 clinical risk group category.

FINDINGS

The likelihood of EDR was higher in all age categories for rural compared to metro residing Medicaid children in New York State. Meeting HEDIS well-child criteria was protective against emergency department (ED) reliance in the adolescence age group (OR = 0.84).

CONCLUSION

ED reliance is associated with rural residence. Increased access to primary and specialty care in rural settings could help reduce EDR, particularly among rural adolescents.

Inequalities in access and utilization of dental services: a cross-sectional study in an area covered by the Family Health Strategy

This cross-sectional study aimed to investigate the presence of inequalities in the access and use of dental services for people living in the coverage area of the Family Health Strategy (FHS) in Ponta Grossa, Paraná State, Brazil, and to assess individual determinants related to them. The sample consisted of 747 individuals who answered a pre-tested questionnaire. Data analysis was performed by chi-square test and Poisson regression analysis, obtaining explanatory models for recent use and, by limiting the analysis to those who sought dental care, for effective access. Results showed that 41% of the sample had recent dental visits. The lowest visit rates were observed among preschoolers and elderly people. The subjects who most identified the FHS as a regular source of dental care were children. Besides age, better socioeconomic conditions and the presence of a regular source of dental care were positively associated to recent dental visits. We identified inequalities in use and access to dental care, reinforcing the need to promote incentives to improve access for underserved populations.

Adolescents' use of the emergency department: does source of primary care make a difference?

BACKGROUND

Many of the 18 million emergency department visits by adolescents annually in the United States are for nonurgent problems that might be addressed in a primary care setting.

METHODS

As part of a larger randomized controlled intervention, 1023 adolescents aged 12 to 21 years registering in an urban pediatric emergency department (PED) were tracked over the subsequent 365 days to record all visits to the PED. Adolescents identifying an adolescent medicine service (AMS) as the primary care source were compared with adolescents receiving primary care elsewhere in an integrated urban medical system (non-AMS) to determine how often after the index PED visit they revisited the PED, returned to primary care (PC), visited a subspecialist (SS), or were hospitalized. Mean values and odds ratios of each type of visit were compared between AMS and non-AMS patients using multivariate logistic and ordinary least squares regressions to control for covariates.

RESULTS

AMS patients (n = 124, 12%), compared to non-AMS patients (n = 899, 88%), were more likely female (75% vs 48%, P < .001) and used public insurance (52% vs 40%, P = .017). In unadjusted comparisons, AMS and non-AMS patients did not differ in the probability of any return PED visit (46% vs 37%, P = .052) in the 365 days following the index PED visit but differed in the mean number of return PED visits (1.35 vs 0.93, P = .026). AMS patients were more likely to be hospitalized (15% vs 7%, P = .006) after the index PED visit and also had a greater mean number of hospitalizations (0.41 vs 0.19, P = .048). Multivariate analyses controlling for demographic variables, triage level of initial PED visit, and hospitalizations showed AMS patients returned to primary care after an index PED visit 24.6 days earlier than non-AMS patients (P = .026).

CONCLUSIONS

This study demonstrates attending an AMS for primary care predicted earlier return to the primary care provider after an index PED visit. Elements of adolescent specialty care producing such outcomes are worthy of further study.

Sickle cell disease in California: sociodemographic predictors of emergency department utilization

BACKGROUND

Patients with sickle cell disease (SCD) visit emergency departments (EDs) in rates leading to a significant health system burden. However, limited comprehensive evaluations of utilization patterns have been published using data connecting visits to patients across facilities. This study aims to examine sociodemographic predictors of ED utilization in SCD.

PROCEDURE

This retrospective cohort study employed 2007 data from the California Office of Statewide Health Planning and Development (OSHPD). Data included all ED encounters from California hospitals; identifiers connected each visit to an individual patient, across all facilities in the state. Multivariate regression techniques evaluated sociodemographic predictors of utilization while adjusting for confounding variables.

RESULTS

In 2007, 2,920 California patients with SCD made 16,364 ED visits. Adults ≥ 21 years of age had higher ED visit rates than children and were more likely to both be in the highest tier of users and visit multiple facilities. Patients living further from a self-identified provider of comprehensive SCD care had higher rates of ED visits and a lower likelihood of hospitalization from the ED. Publicly insured patients had higher rates of ED visits and were more likely to be in the highest tier of users than were the privately insured or uninsured.

CONCLUSIONS

Adulthood ≥ 21 years of age, distance from comprehensive SCD care, and insurance status are significant predictors of ED utilization in SCD. As a routine source of care decreases ED utilization, these findings prompt concern that these factors act as barriers to accessing comprehensive SCD care.

Understanding adolescent and young adult use of family physician services: a cross-sectional analysis of the Canadian Community Health Survey

Background

Primary health care is known to have positive effects on population health and may reduce at-risk behavior and health problems in adolescence. Yet little is known about the factors that are associated with adolescent and young adult utilization of family physician services. It is critical to determine the factors associated with utilization to inform effective primary health care policy. We address this gap in the primary health care literature by examining three issues concerning adolescent and young adult family physician use: inequity; the unique developmental stage of adolescence; and the distinction between utilization (users versus non-users) and intensity (high users versus low users).

Methods

We conducted nested logistic regressions for two outcomes: utilization and intensity of family physician services for early adolescence, middle adolescence, and young adulthood using the 2005 Canadian Community Health Survey.

Results

Chronic conditions were associated with utilization in early and middle adolescence and intensity in all age groups. Respondents from Quebec had lower odds of utilization. Those without a regular medical doctor had much lower odds of being users. The factors associated with use in early and middle adolescence were in keeping with parental involvement while the factors in young adulthood show the emerging independence of this group.

Conclusions

We highlight key messages not known previously for adolescent and young adult use of family physician services. There is inequity concerning regional variation and for those who do not have a regular medical doctor. There is variation in factors associated with family physician services across the three age groups of adolescence. Health care and health care policies aimed at younger adolescents must consider that parents are still the primary decision-maker while older adolescents are more autonomous. There is variation in the factors associated with the two outcomes of utilization and intensity of services. Factors associated with utilization must be understood when considering the equitability of access to primary health care while factors associated with intensity must be understood when considering appropriate use of resources. The understanding gained from this study can inform health care policy that is responsive to the critical developmental stage of adolescence and young adulthood.

Inequalities in dental services utilization among Brazilian low-income children: the role of individual determinants

OBJECTIVES

To assess the role of the individual determinants on the inequalities of dental services utilization among low-income children living in the working area of Brazilian's federal Primary Health Care program, which is called Family Health Program (FHP), in a big city in Southern Brazil.

METHODS

A cross-sectional population-based study was performed. The sample included 350 children, ages 0 to 14 years, whose parents answered a questionnaire about their socioeconomic conditions, perceived needs, oral hygiene habits, and access to dental services. The data analysis was performed according to a conceptual framework based on Andersen's behavioral model of health services use. Multivariate models of logistic regression analysis instructed the hypothesis on covariates for never having had a dental visit.

RESULTS

Thirty one percent of the surveyed children had never had a dental visit. In the bivariate analysis, higher proportion of children who had never had a dental visit was found among the very young, those with inadequate oral hygiene habits, those without perceived need of dental care, and those whose family homes were under absent ownership. The mechanisms of social support showed to be important enabling factors: children attending schools/kindergartens and being regularly monitored by the FHP teams had higher odds of having gone to the dentist, even after adjusting for socioeconomic, demographic, and need variables.

CONCLUSIONS

The conceptual framework has confirmed the presence of social and psychosocial inequalities on the utilization pattern of dental services for low-income children. The individual determinants seem to be important predictors of access.

Disparities in human papillomavirus vaccine series initiation among adolescent girls enrolled in Florida Medicaid programs, 2006-2008

PURPOSE

To better understand the human papillomavirus (HPV) vaccine series initiation among 9-17-year-old female Medicaid beneficiaries in Florida programs between June 2006 and December 2008 (n = 237,015).

METHODS

Among the Florida Medicaid enrollees with itemized claims collected (non-managed care organization enrollees), we assessed the association between HPV vaccine series initiation (≥1 vaccine claim) and important demographic characteristics (age, race/ethnicity, program enrollment, area of residence, and length of enrollment).

RESULTS

Among 11-17-year-olds, vaccine initiation increased over time from <1% by December 2006 to nearly 19% by December 2008. By December 2008, HPV vaccine initiation increased with respect to age from 9 (1.6%) to 13 years (22.9%), remained relatively stable from ages 13 to 15 years (between 21% and 22%), and decreased among 16- (18.6%) and 17-year-olds (15.7%). Compared with girls in Pilot or Fee for Service programs, the girls in MediPass or Children's Medical Service Network programs were more likely to have initiated the vaccine series. Within three of the four programs, Hispanics were more likely than non-Hispanic white and black girls to have initiated the vaccine series.

CONCLUSIONS

This study expands the understanding of HPV vaccine initiation to low-income adolescents eligible for free vaccine through the Federal Vaccine for Children program. Increased understanding of reasons for the observed differences, especially by program and race/ethnicity, will aid in developing interventions to improve HPV vaccine initiation.

Determinantes individuais da utilização de serviços odontológicos por adultos e idosos de baixa renda

A utilização de serviços odontológicos resulta da interação de determinantes biológicos com fatores socioculturais, familiares e comunitários, bem como de características dos sistemas de saúde. O objetivo deste estudo foi identificar os fatores individuais associados à utilização de serviços odontológicos por parte de adultos e idosos de baixa renda residentes na área de abrangência da Estratégia Saúde da Família, em Ponta Grossa, PR. A amostra constou de 246 indivíduos, com 35 anos de idade ou mais, que responderam a um questionário sobre condições socioeconômicas, necessidade percebida e acesso a serviços odontológicos. A análise dos dados foi realizada por meio de regressão logística, segundo referencial teórico baseado no Modelo Comportamental de Andersen, considerando a consulta odontológica não recente como variável dependente. Verificou-se elevada prevalência de problemas bucais auto-referidos e de perdas dentárias. Cerca de 40% dos adultos e 67% dos idosos não iam ao dentista há mais de três anos. Indivíduos que não residiam em domicílios próprios, realizavam higiene bucal com menor frequência e utilizavam próteses totais apresentaram maiores chances de haver utilizado os serviços odontológicos há mais tempo. O fato de possuir um dentista regular foi identificado como fator de proteção na análise. Concluindo, os determinantes individuais mostraram-se importantes indicadores de acesso aos serviços de saúde bucal. O modelo teórico confirmou a presença de desigualdades sociais e psicossociais na utilização de serviços odontológicos entre os adultos e idosos de baixa renda.

A medical home versus temporary housing: the importance of a stable usual source of care

OBJECTIVES

Little is known about how the stability of a usual source of care (USC) affects access to care. We examined the prevalence of USC changes among low-income children and how these changes were associated with unmet health care need.

METHODS

We conducted a cross-sectional survey of Oregon's food stamp program in 2005. We analyzed primary data from 2681 surveys and then weighted results to 84087 families, adjusting for oversampling and nonresponse. We then ascertained the percentage of children in the Oregon population who had ever changed a USC for insurance reasons, which characteristics were associated with USC change, and how USC change was associated with unmet need. We also conducted a posthoc analysis of data from the Medical Expenditure Panel Survey to confirm similarities between the Oregon sample and a comparable national sample.

RESULTS

Children without a USC in the Oregon population had greater odds of reporting an unmet health care need than those with a USC. This pattern was similar in national estimates. Among the Oregon sample, 23% had changed their USC because of insurance reasons, and 10% had no current USC. Compared with children with a stable USC, children who had changed their USC had greater odds of reporting unmet medical need, unmet prescription need, delayed care, unmet dental need, and unmet counseling need.

CONCLUSIONS

This study highlights the importance of ensuring stability with a USC. Moving low-income children into new medical homes could disturb existing USC relationships, thereby merely creating "temporary housing."

Adolescent health care use: investigating related determinants in Greece

The frequency of health care use is crucial for adolescent well-being and health systems. The present study was the first to test a set of variables in a representative sample of Greek adolescents in order to identify factors that predict health care use and contribute to improving health service planning. Questionnaires were administered to a random sample of adolescents (N=1 194) aged 11-18 years and their parents (N=973) in 2003. Data from 894 participants with full data were analyzed. Parents' education, adolescents' chronic health needs, physical well-being and emotional/behavioural problems as well as parent-child relationship were independent predictors of health care use, although some factors, such as gender, age, type of residence, family affluence, social support and parental health status that previous research identified as predictors were not confirmed. Beyond the need of health care, other factors also play an important role in the utilization of health services by adolescents and their families.

Association of medical home care and disparities in emergency care utilization among children with special health care needs

OBJECTIVE

The aim of this study was to determine whether having a medical home is associated with a reduction of racial/ethnic disparities in emergency care utilization by children with special health care needs (CSHCN).

METHODS

We conducted a secondary analysis of 35 301 children, aged 0 to 17, from the 2005-2006 National Survey of Children with Special Health Care Needs. The primary dependent variable was emergency care utilization, defined as 1 or more emergency care encounters in the last 12 months. The primary independent variables were race/ethnicity and type of care (medical home, usual source of care, no medical home/no usual source of care). Multiple logistic regression was conducted to investigate associations between race/ethnicity, type of care, and emergency care utilization.

RESULTS

Analysis of type of care and its interactions with race/ethnicity showed that non-Hispanic black children with a medical home had higher odds (odds ratio [OR] 1.26, 95% confidence interval [CI] 1.03-1.54) of emergency care utilization compared with non-Hispanic white children with a medical home. The odds of having 1 or more emergency care visits were higher for non-Hispanic black children (OR 1.38, 95% CI 1.22-1.56) compared with non-Hispanic white children after controlling for sociodemographic variables. Having a medical home was associated with lower odds of emergency care utilization (OR 0.81, 95% CI 0.72-0.90) compared with having neither a medical home nor a usual source of care.

CONCLUSIONS

Emergency care utilization for CSHCN differed significantly according to race/ethnicity. Having a medical home may be associated with a reduction in disparities in this fragile population.

Who is making lifestyle changes due to preventive health care information? A demographic analysis

This paper sought to describe from a set of demographic and lifestyle characteristics, the person who is significantly and positively impacted by preventive health care (PHC) information. Based on past research, six two-part hypotheses (PHC information and lifestyle) were developed, with a total examination of 12 possible relationships. Five of the six hypotheses were at least partially accepted, as were eight out of the 12 possible relationships. In addition, there was at least one significant relationship with a demographic variable in 12 of the 13 lifestyle change variables. It can be said with confidence that persons who are seeking and are positively impacted by PHC information are better educated, have higher incomes, are female, usually older, and married. The most important lifestyle changes emanating from PHC information are "changes in eating habits," "having periodic physician checkups," "utilizing nutritional labeling," and "joining a health club or wellness center." "Changes in social life," "sleeping habits," "getting regular exercise," and "attendance at health fairs and seminars" were also associated with the utilization of PHC information, but to a lesser extent.

A usual source of care: supplement or substitute for health insurance among low-income children?

OBJECTIVES

To examine the separate and combined effects of having health insurance and a usual source of care (USC) on access to healthcare for low-income children and to determine if one or the other is superior in ensuring better access to necessary services.

METHODS

We conducted cross-sectional, multivariable analyses of data from a mail-return survey of Oregon's food stamp program. Results from 2681 completed surveys were weighted back to a population of 84,087 families with adjustments for oversampling techniques and nonresponse.

RESULTS

Among low-income Oregon children, those with health insurance and a USC reported the best access to healthcare. In multivariable comparisons to this reference group, insured children without a USC had higher rates of unmet medical need [odds ratio (OR) = 2.18; 95% confidence interval (CI): 1.27-3.73]; no doctor visits in 12 months (OR = 6.77; 95% CI: 3.80-12.06); and problems obtaining specialty care (OR = 4.12; 95% CI: 1.59-10.68). Similarly, having a USC but not health insurance was associated with an even higher likelihood of unmet medical needs (OR = 4.33; 95% CI: 2.85-6.57); as well as unmet prescription needs (OR = 2.64, 95% CI: 1.77-3.94), and problems obtaining dental care (OR = 4.83; 95% CI: 3.31-7.06).

CONCLUSIONS

Incremental policy solutions are being proposed that focus on either health insurance coverage for children or expanded access to primary care. However, neither approach displaces the need for the other. The effects of a USC and health insurance, together, are additive predictors of the likelihood that children have optimal access to necessary healthcare services.

Parental nativity affects children's health and access to care

OBJECTIVE

To examine the effect of parental nativity on child health and access to health care.

DATA SOURCE

The 2002 National Survey of America's Families.

RESULTS

Among US children, 14% have foreign-born parents; 5% have one foreign- and one native-born parent ("mixed-nativity"). In multivariate logistic regression analyses, children with foreign-born parents were less likely than children with US-born parents to be perceived in "very good" or "excellent health" [OR = 0.68; 95% CI (0.56-0.82)] and to have a usual health care site [OR = 0.52 (0.38-0.69)]; having mixed-nativity parents is associated with better perceived child health. These effects persisted for minority, but not white, children. Regardless of race and ethnicity, non-citizen children have worse access to care.

CONCLUSION

Efforts to improve children of immigrants' health and access to care should focus on families in which both parents are immigrants, particularly those who are ethnic or racial minorities. Efforts to increase use of health services should focus on non-citizen children.

The financial implications of availability and quality of a usual source of care for children with special health care needs

OBJECTIVE

To examine the relationship of availability and quality of a usual source of care (USC) to medical expenditures overall and for various types of health care services for children with special health care needs (CSHCN), as a group and by four diagnostic subgroups (asthma, non-asthmatic physical conditions, mental retardation, other mental illnesses).

METHODS

Generalized linear models were used to estimate the annual average per capita medical expenditures (APCME) based on data from 820 CSHCN in the 1995 National Health Interview Survey on Disability and 1996 Medical Expenditure Panel Survey.

RESULTS

In 1996, 92% of non-institutionalized CSHCN in the United States had a USC. Of these, 52% were classified as receiving accessible care, 95% received comprehensive care, and 69% received satisfactory care. Approximately 89% of CSHCN had expenditures on health care in 1996 and the APCME was $1,344 for CSHCN as a group. Having a USC was associated with higher expenditures overall and for almost all types of health care services for CSHCN across conditions. Receiving comprehensive care was associated with lower total medical expenditures for CSHCN with asthma, whereas receiving satisfactory care was associated with higher total medical expenditures for CSHCN with non-asthma physical conditions.

CONCLUSION

Having a regular care provider is associated with higher expenditures for CSHCN across diagnosis. Among CSHCN with a USC, quality of care is associated with medical expenditures, although specific associations vary by the quality characteristic and the condition of the child. These results may mask heterogeneity in severity of condition and quality of care over time.

Improving health and building human capital through an effective primary care system

To improve population health, one must put emphasis on reducing health inequities and enhancing health protection and disease prevention, and early diagnosis and treatment of diseases by tackling the determinants of health at the downstream, midstream, and upstream levels. There is strong theoretical and empirical evidence for the association between strong national primary care systems and improved health indicators. The setting approach to promote health such as healthy schools, healthy cities also aims to address the determinants of health and build the capacity of individuals, families, and communities to create strong human and social capitals. The notion of human and social capitals begins to offer explanations why certain communities are unable to achieve better health than other communities with similar demography. In this paper, a review of studies conducted in different countries illustrate how a well-developed primary health care system would reduce all causes of mortalities, improve health status, reduce hospitalization, and be cost saving despite a disparity in socioeconomic conditions. The intervention strategy recommended in this paper is developing a model of comprehensive primary health care system by joining up different settings integrating the efforts of different parties within and outside the health sector. Different components of primary health care team would then work more closely with individuals and families and different healthy settings. This synergistic effect would help to strengthen human and social capital development. The model can then combine the efforts of upstream, midstream, and downstream approaches to improve population health and reduce health inequity. Otherwise, health would easily be jeopardized as a result of rapid urbanization.

Use of a children questionnaire of health-related quality of life (KIDSCREEN) as a measure of needs for health care services

PURPOSE

To check if the expected association is observed between children and adolescents' self-perceived health-related quality of life (HRQL) and the use of health care services.

METHODS

The data come from the pilot test of a European measure of HRQL for children and adolescents (KIDSCREEN). Children answered the KIDSCREEN 52-item pilot version. Visits to a health professional in the past four weeks and hospitalisation in the past 12 months were collected from parents. A logistic regression model was adjusted to analyse the relationship between the use of health services and HRQL.

RESULTS

A total of 2526 children and their parents were included in the analysis. Factors associated to visits in the past four weeks were poor physical well-being (odds ratio [OR] 1.83; 95% confidence interval [CI] 1.42-2.35), and poor school environment (OR 1.32; 95% CI 1.02-1.71). Low scores on moods and emotions was the associated factor to hospitalization in the past 12 months (OR 2.13; 95% CI 1.29-3.81).

CONCLUSIONS

Children and adolescents are a feasible source for their self-assessment of HRQL. They should be taken into account in health care needs studies.

Comparing States on Outcomes for Children with Special Health Care Needs

OBJECTIVES

To develop two alternative methods for comparing and ranking states on the health, health care, and well-being of children with special health care needs (CSHCN).

METHODS

Fifteen key indicators of CSHCN's functional abilities, health insurance coverage, access to care, and the impact of their conditions on their families were identified from the 2001 National Survey of Children with Special Health Care Needs. An initial composite score for each state was created by averaging the state's standardized scores for each of these indicators. Using linear regression analyses and standardized residuals, an adjusted composite score for each state was then created that accounted for demographic variables that differed by state and were related to the initial composite score. States were ranked based on the initial and adjusted composite scores.

RESULTS

The initial composite scores were related to population differences by poverty status, African-American race, and the prevalence of special health care needs. Compared to ranks based on the initial scores, ranks based on the adjusted scores shifted by 10 or more positions for half the states. Hawaii, Rhode Island, Arizona, Iowa, and North Dakota had the highest ("best") adjusted scores.

CONCLUSION

Adjustment to the initial composite scores permits states with different demographic compositions to be compared. The adjusted scores may also help raise awareness of CSHCN's concerns in states where demographic compositions favorable to health outcomes mask the fact that these outcomes are only average (or worse) given the states' demographic compositions.

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.

Equivalent lengths of stay of pediatric patients hospitalized in rural and nonrural hospitals

BACKGROUND

Many children receive their care at local hospitals outside of a large urban area. There may be differences in the length of stay (LOS) between children hospitalized in rural versus urban hospitals. This study compared the differences in LOS, conditional LOS (CLOS), odds of prolonged stay, and 21-day readmission rates for children with 19 medical conditions and 9 surgical procedures admitted to rural, community, and large urban hospitals.

METHODS

Discharge records for the hospitalizations of children 1 to 17 years of age were obtained from the New York Department of Public Health Statewide Planning and Research Cooperative System and the Pennsylvania Health Care Cost Containment Council for April 1996 to July 1998. The 19 medical and 9 surgical conditions were identified with the principal condition and procedure codes. Hospitals were classified into 1 of 5 geographic categories on the basis of United States rural-urban continuum codes, ie, large urban, suburban, moderate urban, small urban, or rural. LOS was defined as the period of time between hospital admission and discharge. Readmission rates were calculated for 21 days after discharge from the hospital. A prolonged stay for each condition was defined as any admission lasting beyond the prolongation point, or the day at which the rate of discharge began to decline, as determined with the Hollander-Proschan statistic. This aspect of LOS describes the ability of providers to treat uncomplicated cases of that specific principle diagnosis. CLOS, as a marker for the management of complicated cases, was defined as the LOS beyond the prolongation point. Cox and logistic regression models were developed to describe the geographic effects on the 4 outcome variables, after severity adjustment with 32 demographic and 11 comorbidity variables and adjustment for hospital clustering.

RESULTS

Medical (N = 114,787) and surgical (N = 29,156) admissions to rural hospitals (N = 12,367) had similar outcomes, compared with all geographic categories except the large urban category. Medical patients admitted to rural hospitals had a shorter LOS (12% increase in discharge rate), a shorter CLOS (12% increase in discharge rate), and lower odds of prolonged stay (odds ratio: 0.80), compared with those in large urban hospitals. Surgical patients admitted to rural hospitals had a shorter LOS (12% increase in discharge rate) and lower odds of prolonged stay (odds ratio: 0.81), compared with those in large urban hospitals. For individual conditions, rural hospitals in general had similar or improved LOS, compared with all other hospitals in the 2 states. The addition of hospital-level variables failed to change the results of the primary models.

CONCLUSIONS

In their treatment of pediatric hospitalized patients, rural hospitals were not significantly different from hospitals in all geographic regions other than large urban areas. Rural hospitals appear to deliver similar care, compared with nonrural hospitals, for many of the common pediatric conditions included in this study. Additional research is needed to apply these results to other regions or states with different geographic distributions of hospitals and children, in order to determine the overall impact on the regionalization of pediatric care.

Voting with their feet: patient exit and intergroup differences in propensity for switching usual source of care

Many analysts advocate patient exit as a strategy for consumers who experience poor-quality care. Exit is believed to have the potential to improve patient welfare by having patients leave (or "exit") poor-performing health care providers, thus signaling their dissatisfaction with the quality of care they have received and thereby admonishing those providers to improve. However, the validity of exit as a signal of consumer dissatisfaction hinges on how closely it reflects dissatisfaction. Intergroup differences in the propensity to exit could also result in unintended consequences. This article examines the association between consumer experience and the decision to change one's usual care providers. It also investigates if there are any intergroup differences in the propensity for changing providers according to insurance status, gender, and race or ethnicity. Data come from household surveys conducted by the Center for Studying Health System Change. Results show significant intergroup differences in propensity for switching usual source of care for voluntary or involuntary reasons related to insurance, rural residency, age, income, race, and ethnicity. Policy implications of the empirical results on exit, voice, and consumerism are discussed.

Primary care providers' willingness to see unaccompanied adolescents

PURPOSE

To describe primary care practitioners' office policies and willingness to provide medical care for unaccompanied adolescents aged 11-17 years.

METHODS

A unique 32-item survey was mailed in June and July, 2001 to 1979 office-based pediatricians and family practitioners randomly selected from the American Medical Association's physician database. The survey included questions regarding demographic information, number of adolescents seen in the practice, office policies regarding adolescents alone in the clinic, and 5-point Likert scales regarding their willingness to see patients in various situations, as well as to see patients in 12 brief clinical scenarios. Predictors of the willingness to see adolescents alone were identified and entered into binomial logistic regression models. Specific policies included on the surveys were coded into groups.

RESULTS

Survey responses (n = 710) represented a 36% response rate. This sample included 288 family practitioners and 368 pediatricians; 43.3% of physicians reported having a specific policy regarding seeing adolescents without their parents present. Family practitioners were more likely than pediatricians to report having such a policy (51.3% vs. 38.2%, p =.001,), yet pediatricians reported a higher percentage of adolescents in their practices than family practitioners (22.6% vs. 12.4%, p <.0005). Not having a policy was an independent predictor of "often" or "always" seeing an adolescent alone for routine health maintenance (OR = 2.84, 95% CI 1.91-4.24) and urgent care visits (OR = 3.01, 95% CI 1.90-4.77). Specific policies varied, and many physicians assessed each case on an individual basis.

CONCLUSIONS

Specific policies are associated with a decreased willingness of physicians to see adolescents who are unaccompanied by a parent. Carefully developed clinic policies that are consistent with legal guidelines should be implemented in order to maximize adolescents' abilities to access care.

Utilization of medical and health-related services among school-age children and adolescents with special health care needs (1994 National Health Interview Survey on Disability [NHIS-D] Baseline Data)

OBJECTIVE

To determine how sociodemographic factors and type of insurance influence use of medical and health-related services by children with special health care needs (CSHCN), after controlling for need.

METHODS

A cross-sectional analysis of 1994 National Health Interview Disability Survey was conducted. Children between 5 and 17 years were identified as chronically ill according to the Questionnaire for Identifying Children with Chronic Conditions (n = 3061). Independent variables included child and family characteristics categorized as predisposing, enabling, and need. Dependent variables included use of 4 medical or 7 health-related services.

RESULTS

Most children (88.7%) had seen a physician; 23.9% had an emergency department visit, 11.4% had a mental health outpatient visit, and 6.4% were hospitalized. Health-related service use ranged from <5.0% (transportation and social work) to 65.1% (medical care coordination); 20% to 30% of children used the remaining services (therapeutic, assistive devices, nonmedical care coordination, housing modifications). In fully adjusted logistic models, children with public insurance were significantly more likely than privately insured children to use 2 of the 4 medical services and 5 of the 7 health-related services. Non-Hispanic black children and children from less educated families were significantly less likely to use many of the services examined.

CONCLUSIONS

In 1994, factors in addition to need influenced medical and health-related service use by CSHCN. Differences in the scope of benefits covered by public insurance compared with private insurance may influence utilization of medical and especially health-related services. Attention is needed to ensure that CSHCN who are racial/ethnic minorities or are from less educated families have access to needed services. Future studies should determine whether these patterns have changed over time.

Health services use by children of migratory agricultural workers: exploring the role of need for care

OBJECTIVE

For migrant children: 1). to assess the determinants of health services use among users and nonusers of health services; 2). to evaluate the association between health status and health services use, while controlling for potential confounders.

DESIGN

A cross-sectional household survey using multistage, partially random sampling to identify migrant families in eastern North Carolina.

PARTICIPANTS

Adult caretakers of 1 randomly selected child under 13 years old.

RESULTS

Forty-four percent of children (N = 300) visited a doctor in the preceding 3 months. Those visiting a doctor disproportionately reported having less than very good health (29% vs 10%), insurance (46% vs 11%), interpreters (45% vs 27%), a family member receiving Special Supplemental Nutrition Program for Women, Infants, and Children (50% vs 16%), and a legal caretaker (30% vs 18%). Compared with those without a doctor visit, a larger proportion of children visiting a doctor were 6 years or younger in age (71% vs 35%), born in the United States (51% vs 15%), female (64% vs 45%), and had not moved in 6 or more months (19% vs 10%). Controlling for enabling resource and sociodemographic confounders, children with less than very good health were 2.4 times more likely than those in very good health to have visited a doctor (95% confidence interval [1.1-5.2]).

CONCLUSIONS

Migrant children using health services are distinct from nonusers with regards to sociodemographic factors, enabling resources, and need for care. Health services use is associated with less than very good perceived health, despite resource barriers and sociodemographic disadvantages. More efforts are needed to improve access to health care for migrant children.

Adolescent substance use, sexual behavior, and metropolitan status: is "urban" a risk factor?

PURPOSE

To determine if urban youth ("metropolitan" status) are at greater risk of engaging in risk behaviors than suburban or rural youth.

METHODS

We analyzed data on substance use and sexual risk behaviors from the national school-based Youth Risk Behavior Survey (YRBS) conducted in 1999, an anonymous questionnaire self-administered by students in grades 9 through 12. The national survey employs a multistage cluster sample to produce a nationally representative sample of high school students. Data were analyzed using SUDAAN software to take into account the sampling model.

RESULTS

In 1999, metropolitan status was not a significant determining factor for involvement in risk behaviors. Of the specific risk factors examined in this analysis, there were no significant differences between rural and suburban youth, and these two groups were combined as "nonurban." In subsequent analysis of urban vs. nonurban youth, no significant differences in risk behaviors were found on bivariate or multivariate analyses.

CONCLUSIONS

This analysis suggests that metropolitan status has little if any association with youth engaging in substance use and sexual risk behaviors. In addition, it appears that urban youth are engaging in these risk behaviors no more frequently than their nonurban counterparts.

Saúde infantil: condições de vida e utilização de serviços de saúde em área da Região Metropolitana de São Paulo, 1996

OBJETIVOS: identificar segmentos populacionais excluídos do sistema de saúde ou que demandassem atuação específica e reorientada dos serviços de saúde. MÉTODOS: estudo transversal, domiciliar, utilizou uma amostra probabilística constituída por 1.099 crianças menores de cinco anos, distribuídas em quatro estratos de condições de vida, residentes no município do Embu, São Paulo, em 1996. O processo de sorteio adotado foi o de conglomerados em dois estágios, tendo-se considerado duas populações independentes: crianças menores de um ano e crianças de um a quatro anos. Foram investigados indicadores da assistência pré-natal, perinatal e de atenção à saúde da criança. Para a análise estatística, foram calculadas as estimativas de proporções, erros padrão, intervalos de confiança (95%), utilizando-se o programa CSample: Epi-info 6.04. RESULTADOS: em todos os estratos, mais de 90% das mães realizaram pré-natal, com acesso tardio no estrato quatro (favelas). Cerca de 80% das crianças menores de um ano eram acompanhadas em serviços de saúde; as unidades básicas de saúde foram mais utilizadas para vacinação (97,4%) e acompanhamento de saúde (79,0%) e os outros serviços de saúde para consultas não marcadas, com maior procura por serviços privados/convênios no estrato um (melhores condições). Nas afecções agudas o serviço de saúde foi a opção de atendimento para quase 100% dos casos. CONCLUSÕES: não se verificou a existência de segmentos populacionais excluídos do sistema de saúde, porém alguns indicadores apontaram para deficiências mais acentuadas no estrato quatro.
