When insurance status is not static: insurance transitions of low-income children and implications for health and health care

The Effect of Health Insurance Status on School Attendance

Introduction Educational achievement is impacted by a student's ability to be present and motivated in the classroom. Since health and education influence one another, disparities in health insurance status among children may exert educationally relevant consequences. However, the association between health insurance coverage and school absenteeism remains poorly understood. Our study aims to assess the association between not having/having gaps in health insurance coverage and an increased number of missed school days. Methods A historical cohort study was performed via secondary analysis of data collected as part of the 2018 National Survey of Children's Health (NSCH). We included children enrolled in school between the ages of 6-17 years and who provided answers to survey questions involving our two variables of interest: health insurance status and missed school days. Our data analysis included 1) a descriptive analysis of the baseline sample characteristics, 2) a bivariate analysis to determine the association between baseline characteristics/confounding variables and the outcome, and 3) a multivariable regression analysis using logistic regression to determine the association of interest while controlling for potential confounding variables. Results A total of 21,498 respondents were included. The unadjusted odds of chronic absenteeism were found to be 16% (OR=1.16) higher in children without insurance or with gaps in insurance compared to children with consistent insurance throughout the year, but the association was not statistically significant (95% CI 0.74 - 1.82, p=0.051). After adjustment by age, sex, race, Hispanic ethnicity, and confounding variables, the odds of chronic absenteeism in children without insurance or with gaps in insurance remained statistically insignificant (aOR=1.05; 95% CI 0.64 - 1.73, p=0.848) compared to those with consistent insurance coverage. Conclusions According to our analysis, the data do not support our hypothesis of a significant difference in missed school days (greater than or equal to 11 missed days of school) among those children who had health insurance compared to those without health insurance/had gaps in insurance coverage.

Association between insurance variability and early lung function in children with cystic fibrosis

BACKGROUND

Lower socioeconomic status (SES) has consistently been associated with poorer outcomes in individuals with cystic fibrosis (CF). Previous studies have compared outcomes for children with and without private insurance coverage, however the potential role of changes in insurance status on early health outcomes in children with CF remains unknown.

OBJECTIVES

To describe the variability in insurance status in early childhood and to evaluate whether insurance variability was associated with poorer outcomes at age 6.

METHODS

Retrospective observational study using the Cystic Fibrosis Foundation Patient Registry. Insurance status was defined as: always private (including Tricare), exclusively public, or intermittent private insurance (private insurance and exclusively public insurance in separate years) during the first 6 years of life. Outcomes at age 6 included body mass index (BMI) and FEV₁ percent predicted (maxFEV₁pp).

RESULTS

From a 2000-2011 birth cohort (n = 8,109), 42.3% always had private insurance, 30.0% had exclusively public insurance, and 27.6% had intermittent private insurance. BMI percentiles did not differ between groups; however, children with intermittent private insurance and exclusively public insurance had a 3.3% and 6.6% lower maxFEV₁pp at age 6, respectively, compared to those with always private insurance.

CONCLUSIONS

A substantial proportion of young children in a modern CF cohort have public or intermittent private insurance coverage. While public insurance has been associated with poorer health outcomes in CF, variability in health insurance coverage may also be associated with an intermediate risk of disparities in lung function as early as age 6.

The value of telemedicine for the pediatric surgery patient in the time of COVID-19 and beyond

BACKGROUND

Prior to COVID-19, the use of telemedicine within pediatric surgery was uncommon. To curb the spread of the virus many institutions restricted non-emergent clinic appointments, resulting in an increase in telemedicine use. We examined the value of telemedicine for patients presenting to a pediatric surgery clinic before and after COVID-19 METHODS: Perspectives and the potential value of telemedicine were assessed by surveying patients or caregivers of patients being evaluated by a general pediatric surgeon in-person prior to COVID-19 and by patients or caregivers of patients who completed a telemedicine appointment with a pediatric surgical provider during the COVID-19 period.

RESULTS

The pre-COVID survey was completed by 57 respondents and the post-COVID survey by 123. Most respondents were white and were caregivers 31-40 years of age. Prior to COVID-19, only 26% were familiar with telemedicine, 25% reported traveling more than 100 miles and >50% traveled more than 40 miles for their appointment. More than 25% estimated additional travel costs of at least $30 and in 43% of households, at least one adult had to miss time from work. Following a telemedicine appointment during the COVID-19 period, 76% reported the care received as excellent, 86% were very satisfied with their care, 87% reported the appointment was less stressful for their child than an in-person appointment, and 57% would choose a telemedicine appointment in the future.

CONCLUSION

For families seeking an alternative to the in-person encounter, telemedicine can provide added value over the traditional in-person encounter by reducing the burden of travel without compromising the quality of care. Telemedicine should be viewed as a viable option for pediatric surgery patients and future research directed toward optimizing the experience for patients and providers.

Electronic health record tools to assist with children's insurance coverage: a mixed methods study

Background

Children with health insurance have increased access to healthcare and receive higher quality care. However, despite recent initiatives expanding children’s coverage, many remain uninsured. New technologies present opportunities for helping clinics provide enrollment support for patients. We developed and tested electronic health record (EHR)-based tools to help clinics provide children’s insurance assistance.

Methods

We used mixed methods to understand tool adoption, and to assess impact of tool use on insurance coverage, healthcare utilization, and receipt of recommended care. We conducted intent-to-treat (ITT) analyses comparing pediatric patients in 4 intervention clinics (n = 15,024) to those at 4 matched control clinics (n = 12,227). We conducted effect-of-treatment-on-the-treated (ETOT) analyses comparing intervention clinic patients with tool use (n = 2240) to intervention clinic patients without tool use (n = 12,784).

Results

Tools were used for only 15% of eligible patients. Qualitative data indicated that tool adoption was limited by: (1) concurrent initiatives that duplicated the work associated with the tools, and (2) inability to obtain accurate insurance coverage data and end dates. The ITT analyses showed that intervention clinic patients had higher odds of gaining insurance coverage (adjusted odds ratio [aOR] = 1.32, 95% confidence interval [95%CI] 1.14–1.51) and lower odds of losing coverage (aOR = 0.77, 95%CI 0.68–0.88), compared to control clinic patients. Similarly, ETOT findings showed that intervention clinic patients with tool use had higher odds of gaining insurance (aOR = 1.83, 95%CI 1.64–2.04) and lower odds of losing coverage (aOR = 0.70, 95%CI 0.53–0.91), compared to patients without tool use. The ETOT analyses also showed higher rates of receipt of return visits, well-child visits, and several immunizations among patients for whom the tools were used.

Conclusions

This pragmatic trial, the first to evaluate EHR-based insurance assistance tools, suggests that it is feasible to create and implement tools that help clinics provide insurance enrollment support to pediatric patients. While ITT findings were limited by low rates of tool use, ITT and ETOT findings suggest tool use was associated with better odds of gaining and keeping coverage. Further, ETOT findings suggest that use of such tools may positively impact healthcare utilization and quality of pediatric care.

Using State Administrative Data to Identify Social Complexity Risk Factors for Children

PURPOSE

Screening for social determinants of health is challenging but critically important for optimizing child health outcomes. We aimed to test the feasibility of using an integrated state agency administrative database to identify social complexity risk factors and examined their relationship to emergency department (ED) use.

METHODS

We conducted a retrospective cohort study among children younger than 18 years with Washington State Medicaid insurance coverage (N = 505,367). We linked child and parent administrative data for this cohort to identify a set of social complexity risk factors, such as poverty and parent mental illness, that have either a known or hypothesized association with suboptimal health care use. Using multivariate analyses, we examined associations of each risk factor and of number of risk factors with the rate of ED use.

RESULTS

Nine of 11 identifiable social complexity risk factors were associated with a higher rate of ED use. Additionally, the rate increased as the number of risk factors increased from 0 to 5 or more, reaching approximately twice the rate when 5 or more risk factors were present in children aged younger than 5 years (incidence rate ratio = 1.92; 95% CI, 1.85-2.00) and in children aged 5 to 17 years (incidence rate ratio = 2.06; 95% CI, 1.99-2.14).

CONCLUSIONS

State administrative data can be used to identify social complexity risk factors associated with higher rates of ED use among Medicaid-insured children. State agencies could give primary care medical homes a social risk flag or score to facilitate targeted screening and identification of needed resources, potentially preventing future unnecessary ED use in this vulnerable population of children.

Conceptualising paediatric health disparities: a metanarrative systematic review and unified conceptual framework

OBJECTIVE

There exists a paucity of work in the development and testing of theoretical models specific to childhood health disparities even though they have been linked to the prevalence of adult health disparities including high rates of chronic disease. We conducted a systematic review and thematic analysis of existing models of health disparities specific to children to inform development of a unified conceptual framework.

METHODS

We systematically reviewed articles reporting theoretical or explanatory models of disparities on a range of outcomes related to child health. We searched Ovid Medline In-Process & Other Non-Indexed Citations, Ovid MEDLINE, Ovid Embase, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus (database inception to 9 July 2015). A metanarrative approach guided the analysis process.

RESULTS

A total of 48 studies presenting 48 models were included. This systematic review found multiple models but no consensus on one approach. However, we did discover a fair amount of overlap, such that the 48 models reviewed converged into the unified conceptual framework. The majority of models included factors in three domains: individual characteristics and behaviours (88%), healthcare providers and systems (63%), and environment/community (56%), . Only 38% of models included factors in the health and public policies domain.

CONCLUSIONS

A disease-agnostic unified conceptual framework may inform integration of existing knowledge of child health disparities and guide future research. This multilevel framework can focus attention among clinical, basic and social science research on the relationships between policy, social factors, health systems and the physical environment that impact children's health outcomes.

A new role for primary care teams in the United States after "Obamacare:" Track and improve health insurance coverage rates

Maintaining continuous health insurance coverage is important. With recent expansions in access to coverage in the United States after "Obamacare," primary care teams have a new role in helping to track and improve coverage rates and to provide outreach to patients. We describe efforts to longitudinally track health insurance rates using data from the electronic health record (EHR) of a primary care network and to use these data to support practice-based insurance outreach and assistance. Although we highlight a few examples from one network, we believe there is great potential for doing this type of work in a broad range of family medicine and community health clinics that provide continuity of care. By partnering with researchers through practice-based research networks and other similar collaboratives, primary care practices can greatly expand the use of EHR data and EHR-based tools targeting improvements in health insurance and quality health care.

Using the electronic health record for assessment of health insurance in community health centers

OBJECTIVE

To demonstrate use of the electronic health record (EHR) for health insurance surveillance and identify factors associated with lack of coverage.

MATERIALS AND METHODS

Using EHR data, we conducted a retrospective, longitudinal cohort study of adult patients (n = 279 654) within a national network of community health centers during a 2-year period (2012-2013).

RESULTS

Factors associated with higher odds of being uninsured (vs Medicaid-insured) included: male gender, age >25 years, Hispanic ethnicity, income above the federal poverty level, and rural residence (P < .01 for all). Among patients with no insurance at their initial visit (n = 114 000), 50% remained uninsured for every subsequent visit.

DISCUSSION

During the 2 years prior to 2014, many patients utilizing community health centers were unable to maintain stable health insurance coverage.

CONCLUSION

As patients gain access to health insurance under the Affordable Care Act, the EHR provides a novel approach to help track coverage and support vulnerable patients in gaining and maintaining coverage.

Medicaid and CHIP retention among children in 12 states

OBJECTIVE

Though stable insurance is important to support optimal child health, the reproducibility of metrics to assess child health insurance retention at the state and county level has not been examined. We sought to determine reproducibility of public insurance retention rates for children using 3 different metrics at the state and county level.

METHODS

Public health insurance retention for children was assessed using 3 different metrics calculated from 2006-2009 Medicaid Analytic Extract data from 12 selected states. The metrics were: 1) Duration: a prospective metric that quantifies the number of newly enrolled children continuously enrolled in public insurance 6, 12, and 18 months after initial enrollment during a selected period; (2) Infant Duration: assesses Duration only among infants born during a selected period; (3) Coverage: a prospective metric that quantifies the average percentage of time a selected population is enrolled over an 18-month interval. Reproducibility of the metrics was assessed using a range of sample sizes with resampling and determining changes in relative rankings of states/counties by retention rate.

RESULTS

All 3 metrics demonstrated reproducible estimates at the state level with sample sizes of 2000, 5000, and 10,000. Reproducibility of relative rankings for child health insurance retention of counties within states were sensitive to county child population size and the amount of variability in retention rates within the county and at the state level.

CONCLUSIONS

As health care reform unfolds, the complete set of these 3 reproducible metrics can be used to evaluate multipronged and multilevel strategies to retain eligible children in public health insurance.

Continuity of Public Insurance Coverage

Publicly financed insurance programs are tasked with maintaining coverage for eligible children, but published measures to assess coverage have not been evaluated. Therefore, we sought to identify and categorize measures of health insurance continuity for children and adolescents. We conducted a systematic review of Medline and HealthStar databases, review of reference lists of eligible articles, and contact with experts. We categorized measures into 8 domains based on a conceptual framework. We identified 147 measures from 84 eligible articles. Most measures evaluated the following domains: always insured (41%), repeatedly uninsured (36%), and transition out of coverage (29%), while fewer assessed single gap in coverage, always uninsured, transition into coverage, change in coverage, and eligibility. Only 18% of measures assessed associations between continuity of coverage and child and adolescent health outcomes. These results suggest that a number of measures of continuity of coverage exist, but few measures have assessed impact on outcomes.

Generational status, health insurance, and public benefit participation among low-income Latino children

The objectives of this study were to (1) measure health insurance coverage and continuity across generational subgroups of Latino children, and (2) determine if participation in public benefit programs is associated with increased health insurance coverage and continuity. We analyzed data on 25,388 children income-eligible for public insurance from the 2003 to 2004 National Survey of Children's Health and stratified Latinos by generational status. First- and second-generation Latino children were more likely to be uninsured (58 and 19%, respectively) than third-generation children (9.5%). Second-generation Latino children were similarly likely to be currently insured by public insurance as third-generation children (61 and 62%, respectively), but less likely to have private insurance (19 and 29%, respectively). Second-generation Latino children were slightly more likely than third-generation children to have discontinuous insurance during the year (19 and 15%, respectively). Compared with children in families where English was the primary home language, children in families where English was not the primary home language had higher odds of being uninsured versus having continuous insurance coverage (OR: 2.19; 95% CI [1.33-3.62]). Among second-generation Latino children, participation in the Food Stamp (OR 0.26; 95% CI [0.14-0.48]) or Women, Infants, and Children (OR 0.40; 95% CI [0.25-0.66]) programs was associated with reduced odds of being uninsured. Insurance disparities are concentrated among first- and second-generation Latino children. For second-generation Latino children, connection to other public benefit programs may promote enrollment in public insurance.

Covered today, sick tomorrow? Trends and correlates of children's health insurance instability

Many children with health insurance will experience gaps in coverage over time, potentially reducing their access to and use of preventive health care services. This article uses the Survey of Income and Program Participation to examine how the stability of children's health insurance changed between 1990 and 2005 and to identify dynamic aspects of family life associated with transitions in coverage. Children's health insurance instability has increased since the early 1990s, due to greater movement between insured and uninsured states and between private and public insurance coverage. Changes in the employment and marital status of the family head are highly associated with an increased risk of a child losing and gaining public and private coverage, largely in hypothesized directions. The exception is that marital dissolution and job loss are associated with an increased probability of a child losing public insurance, despite there being no clear policy explanation for such a relationship.

Public health insurance in Oregon: underenrollment of eligible children and parental confusion about children's enrollment status

OBJECTIVES

We identified characteristics of Oregon children who were eligible for the Oregon Health Plan (OHP), the state's combined Medicaid-Children's Health Insurance Program (CHIP), but were not enrolled in January 2005. We also assessed whether parents' confusion regarding their children's status affected nonenrollment.

METHODS

We conducted cross-sectional analyses of linked statewide Food Stamp Program and OHP administrative databases (n = 10 175) and primary data from a statewide survey (n = 2681).

RESULTS

More than 20% of parents with children not administratively enrolled in OHP reported that their children were enrolled. Parents of 11.3% of children who were administratively enrolled reported that they were not. Eligible but unenrolled children had higher odds of being older, having higher family incomes, and having employed and uninsured parents.

CONCLUSIONS

These findings reveal an important discrepancy between administrative data and parent-reported access to public health insurance. This discrepancy may stem from transient coverage or confusion among parents and may result in underutilization of health insurance for eligible children.

Impact of discontinuity in health insurance on resource utilization

Background

This study sought to describe the incidence of transitions into and out of Medicaid, characterize the populations that transition and determine if health insurance instability is associated with changes in healthcare utilization.

Methods

2000-2004 Medical Expenditure Panel Survey (MEPS) was used to identify adults enrolled in Medicaid at any time during the survey period (n = 6,247). We estimate both static and dynamic panel data models to examine the effect of health insurance instability on health care resource utilization.

Results

We find that, after controlling for observed factors like employment and health status, and after specifying a dynamic model that attempts to capture time-dependent unobserved effects, individuals who have multiple transitions into and out of Medicaid have higher emergency room utilization, more office visits, more hospitalizations, and refill their prescriptions less often.

Conclusions

Individuals with more than one transition in health insurance status over the study period were likely to have higher health care utilization than individuals with one or fewer transitions. If these effects are causal, in addition to individual benefits, there are potentially large benefits for Medicaid programs from reducing avoidable insurance instability. These results suggest the importance of including provisions to facilitate continuous enrollment in public programs as the United States pursues health reform.

Mental illness as a risk factor for uninsurance among mothers of infants

The objective of this study was to assess the extent to which maternal prenatal mental illness is associated with mothers' health insurance status 12-18 months after giving birth. The sample consisted of 2,956 urban, mostly unwed, mothers who gave birth in 20 large U.S. cities between 1998 and 2000 and participated in the Fragile Families and Child Wellbeing birth cohort study. Multinomial logistic regression models were used to assess associations between maternal prenatal mental illness and whether the mother had private, public, or no insurance one year after the birth. Covariates included the mother's and child's physical health status, the father's physical and mental health status, and numerous other maternal, paternal, and family characteristics. Potential mediating factors were explored. The results showed that mothers with prenatal diagnosed mental illness were almost half as likely as those without mental illness diagnoses to have private insurance (vs. no insurance) one year after the birth. Among mothers who did not have a subsequent pregnancy, those with prenatal mental illness were less likely than those without mental illness diagnoses to have public insurance than to be uninsured. Screening positive for depression or anxiety at one year decreased the likelihood that the mother had either type of insurance. Policies to improve private mental health care coverage and public mental health services among mothers with young children may yield both private and social benefits. Encounters with the health care and social service systems experienced by pregnant and postpartum women present opportunities for connecting mothers to needed mental health services and facilitating their maintenance of health insurance.

Lapses in Medicaid coverage: impact on cost and utilization among individuals with diabetes enrolled in Medicaid

BACKGROUND

Gaps in Medicaid coverage can result in inadequate access to care. This can be particularly detrimental to those with a chronic disease such as diabetes.

OBJECTIVE

To assess whether a lapse in Medicaid coverage is associated with an increase in expenditures, and acute care utilization upon reenrollment among beneficiaries with diabetes.

RESEARCH DESIGN

Using multivariate regression analyses, we compared pre- versus post-expenditures and utilization among 2102 individuals with diabetes who had experienced at least one 1-month lapse in their Medicaid coverage.

MEASURES

Dependent variables were the number of inpatient episodes, total length of stay, total number of emergency room visits, total expenditure, and pharmaceutical expenditures. These were aggregated over 3-month spans that either immediately preceded or immediately followed a lapse in coverage. Key predictor variables included a variable that identified the span as occurring pre-lapse or post-lapse in coverage, and a continuous variable identifying the length of the lapse. Predicted expenditure and utilization were calculated.

RESULTS

Overall total program expenditures were higher for post-lapse periods compared with pre-lapse periods. Total expenditures were estimated to increase by $239 per member per month for the 3-month period. The likelihood of having any expenditure was actually lower in the post-lapse period. However inpatient and emergency room use was higher.

CONCLUSIONS

The results from this study suggest that interruptions in Medicaid coverage are associated with overall greater program expenditures in the post-lapse periods. However, this increase in expenditures seems to be driven by a subset of individuals whose greater use of inpatient and emergency room services increased overall program costs.

The effects of varying periods of uninsurance on children's access to health care

OBJECTIVE

Many studies have documented the adverse consequences of uninsurance for children, but less is known about the differential effects of varying periods of uninsurance. This study examines the relative effects of varying periods of uninsurance (uninsured for 1-4 months, 5-11 months, or all year) on children's access to care.

METHODS

Using data from the 2005 California Health Interview Survey Children's File (ages 0-11), we estimated logistic regressions to examine the effect of insurance status on 6 measures of health care access, controlling for child demographics, child health status, family characteristics, and urban residence. Indicators for insurance status included the following categories: (1) privately insured all year (reference); (2) Medicaid all year; (3) State Children's Health Insurance Program all year; (4) uninsured for 1 to 4 months; (5) uninsured for 5 to 11 months; (6) uninsured all year; and (7) other insurance all year.

RESULTS

We found that children who experience short spells of uninsurance (1-4 months) are less likely to have a usual source of care and are more likely to experience delays in needed care than those with continuous private or public insurance. The consequences are even worse for children who experience more substantial periods of uninsurance, because they are also less likely to receive preventive care (well-child visits and flu shots) or visit the doctor during the year and are more likely to experience delays in receiving needed medical care and prescriptions than those with continuous coverage. The Medicaid program and State Children's Health Insurance Program in California both seem to have ensured levels of health care access similar to that obtained by children with year-round private coverage.

CONCLUSIONS

These findings highlight the benefits gained through continuous health insurance, whether public or private. Public policies should be adopted to ensure continuity of coverage and retention in public insurance programs.

An investment in health: anticipating the cost of a usual source of care for children

OBJECTIVES

Among adults, having a usual source of care has been associated with lower health care expenditures primarily through decreased emergency department and inpatient expenditures. The extent of this effect among children is unknown. We hypothesized that children with a usual source of care would have greater odds of having any outpatient expenditures, lower odds of emergency department and inpatient expenditures, and lower expenditures overall.

PATIENTS AND METHODS

Using a 2-part model, we studied expenditures among children < or =17 years of age in the 2004 Medical Expenditure Panel Survey (N = 8810). Logistic regression was used to assess the relationship between having a usual source of care and the odds of having any outpatient, emergency department, and inpatient expenditures, and ordinary least-squares regression was used to compare the amount of total, outpatient, emergency department, and inpatient expenditures among children with and without a usual source of care, controlling for confounders.

RESULTS

The odds of having any expenditures overall and any outpatient expenditures were 2.42 and 2.91 times higher among children with a usual source of care than among those without a usual source of care. The odds of having any emergency department or inpatient visits did not differ between groups. Having a usual source of care was associated with higher total expenditures and lower inpatient expenditures.

CONCLUSIONS

Having a usual source of care is associated with increased odds of having any expenditures overall and any outpatient expenditures, higher total expenditures, and lower inpatient expenditures. Because emergency department and inpatient visits are less common among children than among adults, reductions in receipt of such care do not offset the associated increase in total expenditures and may not be appropriate indicators of the benefit of having a usual source of care among children. Intermediate indicators such as receipt of age-appropriate preventive services should be assessed.

Obtaining health care services for low-income children: a hierarchy of needs

INTRODUCTION

Basic health care is beyond the reach of many families, partly due to lack of health insurance. Many of those with insurance also experience unmet need and limited access. In this study, low-income parents illuminate barriers to obtaining health care services for their children.

METHODS

We surveyed a random sample of families from Oregon's food stamp population with children eligible for public insurance, based on household income. Mixed-methods included: (1) multivariable analysis of data from 2,681 completed surveys, and (2) qualitative study of written narratives from 722 parents.

RESULTS

Lack of health insurance was the most consistent predictor of unmet health care needs in the quantitative analysis. Qualitatively, health insurance instability, lack of access to services despite having insurance, and unaffordable costs were major concerns.

CONCLUSIONS

Parents in this low-income population view insurance coverage as different from access to services, and reported a hierarchy of needs. Insurance was the primary concern; access and costs were secondary.

Partial-year insurance coverage and the health care utilization of children

A large literature examines the effects of health insurance on the health care utilization of children; however, most existing studies conceptualize coverage as a point-in-time measure rather than as a dynamic phenomenon. The major contribution of this article is its provision of estimates on the relationship between the duration of coverage over the course of a calendar year and health care utilization among children. Using child-level fixed-effects regression, we find that an incremental uninsured month is associated with a 0.7 percentage point decline in the probability of receiving a visit over the course of a year and a 3% decrease in the number of visits received. Children with intrayear coverage losses are more likely than those with continuous coverage to lose their usual source of care, which serves as a potential mechanism through which short gaps in coverage may lead to longer-term decrements in utilization.

"Mind the Gap" in children's health insurance coverage: does the length of a child's coverage gap matter?

OBJECTIVE

Gaps in health insurance coverage compromise access to health care services, but it is unclear whether the length of time without coverage is an important factor. This article examines how coverage gaps of different lengths affect access to health care among low-income children.

METHODS

We conducted a multivariable, cross-sectional analysis of statewide primary data from families in Oregon's food stamp population with children presumed eligible for publicly funded health insurance. The key independent variable was length of a child's insurance coverage gap; outcome variables were 6 measures of health care access.

RESULTS

More than 25% of children reported a coverage gap during the 12-month study period. Children most likely to have a gap were older, Hispanic, lived in households earning between 133% and 185% of the federal poverty level, and/or had an employed parent. After adjusting for these characteristics, in comparison with continuously insured children, a child with a gap of any length had a higher likelihood of unmet medical, prescription, and dental needs; no usual source of care; no doctor visits in the past year; and delayed urgent care. When comparing coverage gaps, children without coverage for longer than 6 months had a higher likelihood of unmet needs compared with children with a gap shorter than 6 months. In some cases, children with gaps longer than 6 months were similar to, or worse off than, children who had never been insured.

CONCLUSIONS

State policies should be designed to minimize gaps in public health insurance coverage in order to ensure children's continuous access to necessary services.

The impact of health insurance gaps on access to care among children with asthma in the United States

BACKGROUND

Health insurance coverage is important to help assure children appropriate access to medical care and preventive services. Insurance gaps could be particularly problematic for children with asthma, since appropriate preventive care for these children depends on frequent, consistent contacts with health care providers.

OBJECTIVE

The aim of this study was to determine the association between insurance gaps and access to care among a nationally representative sample of children with asthma.

METHODS

The National Survey of Children's Health provided parent-report data for 8097 children with asthma. We identified children with continuous public or continuous private insurance and defined 3 groups with gaps in insurance coverage: those currently insured who had a lapse in coverage during the prior 12 months (gained insurance), those currently uninsured who had been insured at some time during the prior 12 months (lost insurance), and those with no health insurance at all during the prior 12 months (full-year uninsured).

RESULTS

Thirteen percent of children had coverage gaps (7% gained insurance, 4% lost insurance, and 2% were full-year uninsured). Many children with gaps in coverage had unmet needs for care (7.4%, 12.8%, and 15.1% among the gained insurance, lost insurance, and full-year uninsured groups, respectively). In multivariate models, we found significant associations between insurance gaps and every indicator of poor access to care among this population.

CONCLUSIONS

Many children with asthma have unmet health care needs and poor access to consistent primary care, and lack of continuous health insurance coverage may play an important role. Efforts are needed to ensure uninterrupted coverage for these children.

Discontinuity of coverage for Medicaid and S-CHIP children at a transitional birthday

RESEARCH OBJECTIVE

To investigate disenrollment from public insurance at the 6-year transitional birthday when eligibility for many children moves from Medicaid to State Children's Health Insurance Program (S-CHIP).

DATA SOURCES

Data from Georgia's S-CHIP (PeachCare) and Medicaid programs from 2000 to 2002.

STUDY DESIGN

The likelihood of dropping public coverage after the reference birthday is modeled for children turning age 6 compared with a control cohort of children turning age 9 controlling for demographic and geographic differences between enrollees.

PRINCIPAL FINDINGS

Over 17 percent of 6-year-olds versus only 7 percent of the control cohort dropped coverage. After controlling for other factors (e.g., race/ethnicity, prior enrollment, and geographic region) having lower historical expenditures is predictive of dropping coverage among all children, although the unadjusted effect is stronger among children enrolled in PeachCare before their sixth birthday. Only 1 percent of Medicaid children who remained covered transitioned to PeachCare.

CONCLUSIONS

Turnover at transitional birthdays identifies a common pathway for children into the ranks of the uninsured. Facilitating continuous enrollment would retain in the programs children with lower than average expenditures. This may be one of the more cost effective ways of reducing the number of uninsured children in Georgia.

Disruptions in insurance coverage: patterns and relationship to health care access, unmet need, and utilization before enrollment in the State Children's Health Insurance Program

BACKGROUND

The numbers and types of disruptions in insurance that children experience and the effects of these disruptions on health care measures have not been well characterized.

OBJECTIVES

Our goals were to (1) describe the number and patterns of insurance disruptions within a population of children newly enrolling into the State Children's Health Insurance Program and (2) assess the relationship among insurance disruptions and sociodemographic characteristics of these children and their families to specific measures of access to care, unmet need, and health care utilization during the year before enrollment.

METHODS

We conducted telephone interviews in families with children newly enrolling in the State Children's Health Insurance Program. Families reported on measures for each of the 12 months preceding enrollment. They were grouped by number of insurance disruptions in the year before enrollment: continuously uninsured, > or = 2 disruptions, 1 disruption, or continuously insured.

RESULTS

Of 920 families contacted, 739 (80%) completed the interview and 710 had useable data. Thirty-five percent reported being continuously uninsured, 42% were intermittently insured (> or = 2 disruptions: 28%; 1 disruption: 14%), and 23% were continuously insured during the previous year. The most common patterns of change were between privately insured and uninsured (49%) and Medicaid and uninsured (40%). The continuously uninsured were more likely to be Hispanic and older in age. Multivariate modeling confirmed a gradient between greater insurance disruption and less access to care, less utilization, and greater unmet medical need. Using the continuously uninsured as a reference group, the adjusted odds ratio for having a medical home varied from 2.5 for those with > or = 2 disruptions to 4.5 for the continuously insured and from 1.9 to 3.2, respectively, for using any regular/routine care. The odds ratio for unmet need for a prescription medication was 0.9 for > or = 2 disruptions and 0.5 for those with continuous insurance coverage.

CONCLUSIONS

There was significant disruption in insurance coverage in the year before State Children's Health Insurance Program enrollment. Most of these disruptions took the form of children previously enrolled in either Medicaid or private insurance becoming uninsured. Increasing numbers of disruptions were associated with less routine care and greater unmet medical need. These findings suggest that disruptions in insurance coverage for children should be minimized with the adoption of policies regarding continuous eligibility criteria for Medicaid and streamlining transitions between Medicaid, the State Children's Health Insurance Program, and private insurance.

How stable is medicaid coverage for children?

We examined Medicaid coverage patterns in five states for children who were covered as of December 2003. Looking back three years, we found that Medicaid was a source of continuous coverage for sizable proportions of children (43-66 percent were covered for two or more years) but a revolving door for others (16-41 percent had gaps). In all states, gaps were short, from two to four months. Continuity implies that states can demand more of the health care system to improve the quality of care; short gaps imply that policies and procedures should be revisited to reduce gaps for eligible children.

The association of health insurance and continuous primary care in the medical home on vaccination coverage for 19- to 35-month-old children

OBJECTIVE

Our goal was to examine the association of continuous care in the medical home and health insurance on up-to-date vaccination coverage by using data from the National Survey of Children's Health and the National Immunization Survey.

METHODS

Interviews were conducted with 5400 parents of 19- to 35-month-old children to collect data on demographics and medically-verified vaccinations. Health insurance coverage was categorized as always, intermittently, or uninsured for the previous 12 months. Insurance types were private, public, or uninsured. Having a personal doctor or nurse and receiving preventive health care in either the past 12 or 24 months constituted continuous primary care in the medical home. Children were up-to-date if they received all vaccinations by 19 to 35 months of age (>or=4 doses of diphtheria and tetanus toxoids and pertussis vaccine, >or=3 doses of poliovirus vaccine, >or=1 dose of any measles-containing vaccine, >or=3 doses of Haemophilus influenzae type b vaccine, and >or=3 doses of hepatitis B vaccine).

RESULTS

Bivariate analyses revealed children who were always insured had significantly higher vaccination coverage (83%) than those with lapses or uninsured during the past 12 months (75% and 71%, respectively). Those with continuous primary care in the medical home had significantly higher coverage than those who did not (83% vs 75%, respectively). In multivariate analysis, the same pattern of association was observed for insurance status and medical home, but the only statistically significant association was for children of never-married mothers who had significantly lower coverage (74%) compared with children of married mothers (84%).

CONCLUSIONS

Among children with the same insurance status and continuity of care in the medical home, children of single mothers were less likely to be up-to-date than children of married mothers. Interventions assisting single mothers to obtain preventive care for their children should be a priority.

Underinsurance and key health outcomes for children with special health care needs

OBJECTIVE

The objective was to examine the relationship between underinsurance and other core outcomes for children with special health care needs.

METHODS

This study analyzed data from the National Survey of Children With Special Health Care Needs. Two alternative definitions of underinsurance, designated attitudinal and economic, were investigated. Logistic regression models in which the response variables were the child's status for each of the target core outcomes and underinsurance status was a dichotomous predictor variable were created. In addition to underinsurance status, 10 other predictor variables were included in the model.

RESULTS

Underinsurance is associated with the Maternal and Child Health Bureau core outcomes for children with special health care needs related to satisfaction with care and partnering with families in decision-making, access to a medical home, community-based service delivery that is easy to use, and access to services to make transitions to adulthood. In each case, children with special health care needs who were underinsured had significantly poorer outcomes than did children who were adequately insured.

CONCLUSIONS

Although these results cannot clarify the cause of poorer outcomes, there are clear negative effects associated with the problem of underinsurance. Inadequate health care coverage for children with special health care needs may save dollars in the short-term but, if other outcomes are compromised, then children, their families, and society at large may pay a price in the longer term.

The impact of Medicaid on children's healthcare and health

PURPOSE OF REVIEW

This article reviews the impact of the Medicaid program, including the proportion of children in America insured by Medicaid; the extent to which Medicaid-enrolled children have access to care; the use of services and the quality of care received by Medicaid enrollees, including evidence for disease reduction; and family satisfaction with the program.

RECENT FINDINGS

More than a quarter of all children in the United States were insured through public programs, primarily Medicaid, in 2002. Public insurance programs are even more critical for low-income children: 69.5% of children in families with incomes below 100% of the federal poverty level are covered by public programs. The reach of Medicaid is extensive, although substantial numbers of eligible children remain uninsured. Although Medicaid-insured children still face access barriers, particularly for certain types of specialty care, parents of children with public insurance report high levels of satisfaction with their experience with well-child care. While the study findings are mixed, several recent studies show very favorable comparisons between the experience of privately insured children and that of publicly insured children.

SUMMARY

Medicaid plays a critical role in providing health insurance coverage for children, particularly for very low-income families. Additional efforts are needed to fully enroll all eligible families and to assure full access to high-quality care.

Association between underinsurance and access to care among children with special health care needs in the United States

OBJECTIVE

To examine the impact of underinsurance on access to care among children with special health care needs (CSHCN) in the United States.

METHODS

Interviews were conducted by telephone with the families of 38866 CSHCN who were younger than 18 years using the 2001 National Survey of Children With Special Health Care Needs. The prevalence of underinsurance and its relationship to access to care and family financial problems was examined in this cross-sectional analysis. CSHCN were classified as underinsured when coverage was deemed inadequate to meet the child's needs.

RESULTS

An estimated 12.8% of US children experienced a special health care need in 2001. Although 95% of CSHCN had some type of insurance coverage at the time of the interview, 32% were classified as underinsured. Underinsured CSHCN were disproportionately represented in low-income families and were significantly more likely than fully insured children to have unmet health needs, and their families were more likely to report difficulty in obtaining specialty referrals, experience financial problems, and report that the child's condition caused family members to reduce or stop work. Underinsured CSHCN seemed to be somewhat better off than CSHCN with no insurance coverage on these measures.

CONCLUSIONS

Underinsured CSHCN represent an important and largely hidden underserved population.

Defining underinsurance among children with special health care needs: a Virginia sample

OBJECTIVES

The study sought to: 1) examine the national Children with Special Health Care Needs (CSHCN) survey to determine whether there are items that can serve to operationalize alternative definitions of underinsurance; 2) construct definitions from the survey items that are consistent with Structural and Economic definitions of underinsurance and devise an algorithm for determining underinsurance for each; and 3) compare these two underinsurance definitions with the Maternal and Child Health definition of inadequate insurance, a definition that takes an Attitudinal approach to the construct.

METHODS

Analyses included Virginia children who were insured throughout the survey period. Survey items from the national CSHCN survey were examined to identify items related to underinsurance. Items were divided into groups corresponding to three definitions of insurance (Attitudinal, Structural, and Economic). Algorithms were established, and underinsurance rates calculated for each definition. Logistic regression models were constructed to investigate demographic characteristics related to underinsurance.

RESULTS

Different percentages of Virginia CSHCN were found to be underinsured based on the definitions of Attitudinal (28.9%), Economic (25.6%), and Structural (2.9%). Eight demographic characteristics and the pervasiveness of the child's special health care needs were examined in relation to underinsurance. For the Attitudinal definition, poverty level and pervasiveness were significant predictors in the model. In the model predicting Economic underinsurance status, pervasiveness and three of the demographic characteristics significantly predicted underinsurance status. In the multivariate logistic regression model for the Structural definition, none of the predictors was significantly related to underinsurance.

CONCLUSIONS

These findings demonstrate that alternative definitions of underinsurance yield dramatically different underinsurance rates. Further, even when yielding similar rates, alternative definitions may identify substantially different sets of children. The likelihood of being underinsured has a strong association with low-income status and pervasiveness of the child's special health care needs. Understanding these factors and their implications will be important when planning accessible and comprehensive health plans and care systems for CSHCN.

Children in the United States with discontinuous health insurance coverage

BACKGROUND

Estimates of the number of uninsured people in the United States usually exclude those with discontinuous coverage. The effects of gaps in insurance coverage for children on access to and use of ambulatory care are poorly understood.

METHODS

We analyzed a sample of 26,955 children under 18 years of age from the 2000 and 2001 National Health Interview Surveys. Children with discontinuous health insurance coverage were compared with those who were uninsured all year and with those who had public or private full-year coverage.

RESULTS

During the last 12 months before they were interviewed, 6.6 percent of children in the United States had no insurance and an additional 7.7 percent had gaps in insurance. Children who had full-year insurance coverage (private or public) had low rates of unmet health care needs and good access to care (delayed care, unmet medical care, and unfilled prescriptions were reported in <3 percent, and <5 percent had no usual place of care). Access to care was much worse for children who were uninsured for part of the year and for those who were uninsured for the full year (delayed care, 20.2 percent and 15.9 percent, respectively; unmet medical care, 13.4 percent and 12.6 percent, respectively; unfilled prescriptions, 9.9 percent and 10.0 percent, respectively; P<0.01 for all comparisons with children with full-year, private insurance coverage). In multivariate analyses adjusting for age, income, race or ethnic group, region, citizenship, family structure, parental employment, and health status, the differences in access to care persisted. As compared with the parents of children with full-year, private insurance, parents of children uninsured for the full year were far more likely to report delaying care (adjusted odds ratio, 12.65; 95 percent confidence interval, 9.45 to 16.94), as were parents of children uninsured for part of the year (adjusted odds ratio, 13.65; 95 percent confidence interval, 10.41 to 17.90).

CONCLUSIONS

Children with gaps in health insurance coverage commonly do not seek medical care, including preventive visits, and do not get prescriptions filled. These findings are important for both research and policy and point to the need for more encompassing and sensitive measures of the situation of being uninsured.

Medical home, obesity, acute otitis media, and otitis media with effusion

Four areas of pediatric office practice are reviewed: the medical home concept, obesity, acute otitis media, and otitis media with effusion. The concept of the medical home in the care of children with special health care needs, its effect on health care outcomes, and its application to office practice are discussed. The epidemiology and causes of obesity are covered along with options for obesity screening and prevention. Diagnosis and therapy of acute otitis media and otitis media with effusion are reviewed along with discussion of recent practice guidelines for both entities.
