The State Children’s Health Insurance Program: Successes, Shortcomings, And Challenges

Patterns of treatment for psychiatric disorders among children and adolescents in Mississippi Medicaid

The nature of services for psychiatric disorders in public health systems has been understudied, particularly with regard to frequency, duration, and costs. The current study examines patterns of service reception and costs among Medicaid-covered youth newly diagnosed with anxiety, depression, or behavioral disturbance in a large data set of provider billing claims submitted between 2015-2016. Eligibility criteria included: 1) identification of an initial diagnosis of a single anxiety, unipolar mood, or specific behavioral disorder; 2) continuous Medicaid eligibility over the duration of the time period studied; and 3) under 18 years of age on the date of initial psychiatric diagnosis. The final cohort included 7,627 cases with a mean age of 10.65 (±4.36), of which 58.04% were male, 57.09% were Black, 38.97% were White, and 3.95% were of other ethnicities. Data indicated that 65.94% of the cohort received at least some follow-up services within a median 18 days of diagnosis. Of those, 54.27% received a combination of medical and psychosocial services, 32.01% received medical services only, and 13.72% received psychosocial services only. Overall median costs for direct treatment were $576.69, with wide discrepancies between the lowest (anxiety = $308.41) and highest (behavioral disturbance = $653.59) diagnostic categories. Across all categories the frequency and duration of psychosocial services were much lower than would be expected in comparison to data from a well-known effectiveness trial. Overall, follow-up to psychiatric diagnosis could be characterized as highly variable, underutilized, and emphasizing biomedical treatment. Understanding more about these patterns may facilitate systematic improvements and greater cost efficiency in the future.

Supply-side effects from public insurance expansions: Evidence from physician labor markets

Medicaid and the Child Health Insurance Programs (CHIP) are key sources of coverage for U.S. children. Established in 1997, CHIP allocated $40 billion of federal funds across the first 10 years but continued support required reauthorization. After 2 failed attempts in Congress, CHIP was finally reauthorized and significantly expanded in 2009. Although much is known about the demand-side policy effects, much less is understood about the policy's impact on providers. In this paper, we leverage a unique physician dataset to examine if and how pediatricians responded to the expansion of the public insurance program. We find that newly trained pediatricians are 8 percentage points more likely to subspecialize and as much as 17 percentage points more likely to enter private practice after the law passed. There is also suggestive evidence of greater private practice growth in more rural locations. The sharp supply-side changes that we observe indicate that expanding public insurance can have important spillover effects on provider training and practice choices.

The search for a national child health coverage policy

Thirty-eight percent of US children depend on publicly financed health insurance, reflecting both its expansion and the steady erosion of employment-based coverage. Continued funding for the Children's Health Insurance Program (CHIP) is an immediate priority. But broader reforms aimed at improving the quality of coverage for all insured children, with a special emphasis on children living in low-income families, are also essential. This means addressing the "family glitch," which bars premium subsidies for children whose parents have access to affordable self-only employer-sponsored benefits. It also means addressing the quality of health plans sold in the individual and small-group markets-whether or not purchased through the state and federal exchanges-that are governed by the "essential health benefit" standard of the Affordable Care Act (ACA). In this article we examine trends in coverage and the role of Medicaid and CHIP. We also consider how the ACA has shaped child health financing, and we discuss critical issues in the broader insurance market and the need to ensure plan quality, including the scope of coverage, use of a pediatric medical necessity standard that emphasizes growth and development, the structure of pediatric provider networks, and attention to the quality of pediatric health care.

Does expanding public insurance prevent material hardship for families with children?

The 1997 Children's Health Insurance Program (CHIP) provided states with funding to expand public insurance to children in low-income families. Recent studies suggest CHIP improved family finances, but it is unknown whether CHIP specifically affected the prevalence of material hardships such as food and housing insecurity. This study uses cross-sectional data on low-income children from the National Survey of American Families (1997-2002) to examine the impact of CHIP on material hardships. Using an instrumental variable that exploits variation in income eligibility cutoffs across states and years, I find that households gaining CHIP eligibility did not experience significant changes in material hardship. CHIP significantly reduced the prevalence of postponed care for the subgroup of households close to the poverty line. For low-income families with children, public health insurance may play a larger role in increasing access to care than in supplementing the budget for necessities.

The Impact of the Medicaid/CHIP Expansions on Children

This article reviews findings from 38 rigorous studies published in the peer-reviewed literature of the impact of the Medicaid/Children’s Health Insurance Program (CHIP) expansions on children. There is strong evidence for increases in enrollment in public programs and reductions in uninsurance following eligibility expansions. Medicaid enrollment continued to increase during the CHIP era (a “spillover effect”). Evidence for improved access to and use of services, particularly for dental care, is also very strong. There are fewer studies of health status impacts, and the evidence is mixed. There is a very wide range in the size of effects estimated in the studies reviewed because of the methods used and the populations studied. The review identifies several important research gaps on this topic, particularly the small number of studies of the effects on health status. Both research methods and findings from the child expansions can provide insights for evaluating the coming expansions for adults under the Affordable Care Act.

CHIP premiums, health status, and the insurance coverage of children

This study uses the introduction of premiums into Kentucky's Children's Health Insurance Program (KCHIP) to examine whether the enrollment impact of new premiums varies by child health type. We also examine the extent to which children find alternative coverage after premium nonpayment. Public insurance claims data suggest that those with chronic health conditions are less likely to leave public coverage. We find little evidence of a differential impact of premiums on enrollment among the chronically ill. Our survey of nonpayers shows that 56% of responding families found alternative private or public health coverage for their children after losing CHIP.

Improving children's healthcare through state health insurance programs: an emerging need

OBJECTIVES

State Children's Health Insurance Program (SCHIP) in the USA plays a critical role in healthcare service utilization. This study assesses children's needs for healthcare services among the variations of SCHIP.

METHODS

This study applies the PRECEDE-PROCEED behavioral model to analyze the behavior of children with healthcare needs and unmet healthcare needs by using the National Survey of Children with Special Healthcare Needs of the USA.

RESULTS

Children who were previously under a Medicaid program are apt to enroll in SCHIP programs. SCHIP children with healthcare needs are more likely than comparable non-SCHIP children to use hospital outpatient departments instead of using doctors' offices and health centers. Children under the SCHIP single and SCHIP combination programs are more likely to use doctors' offices and health centers than those in the Medicaid expansion program. SCHIP combination or SCHIP Medicaid expansion states are significantly less likely to have unmet healthcare needs than children in SCHIP single states.

CONCLUSIONS

Medicaid has a significant impact on the SCHIP program. There is a substitution of healthcare service facilities between hospital outpatient departments and either the doctors' offices or health centers.

SCHIP premiums, enrollment, and expenditures: a two state, competing risk analysis

Faced with state budget troubles, policymakers may introduce or increase State Children's Health Insurance Program (SCHIP) premiums for children in the highest program income eligibility categories. In this paper we compare the responses of SCHIP recipients in a state (Kentucky) that introduced SCHIP premiums for the first time at the end of 2003 with the responses of recipients in a state (Georgia) that increased existing SCHIP premiums in mid-2004. We start with a theoretical examination of how these different policies create different changes to family budget constraints and produce somewhat different financial incentives for recipients. Next we empirically model the impact of these policies using a competing risk approach to differentiate exits due to transfers to other eligibility categories of public coverage from exiting the public health insurance system. In both states we find a short-run increase in the likelihood that children transfer to lower- income eligibility/lower-premium categories of SCHIP. We also find a short-run increase in the rate at which children transfer from SCHIP to Medicaid in Kentucky, which is consistent with our theoretical model. These findings have important financial implications for state budgets, as the matching rates and premium levels are different for different eligibility categories of public coverage.

Recent trends in State Children's Health Insurance Program eligibility and coverage for CSHCN

OBJECTIVE

Policy makers and physicians need to understand recent trends in State Children's Health Insurance Program (SCHIP) eligibility and coverage given the ongoing debate on SCHIP. Although many studies have examined these issues, few have focused on children with special health care needs (CSHCN). With this study we aimed to fill this gap in the literature.

METHODS

Data on state-specific SCHIP eligibility criteria were merged with the National Survey of Children With Special Health Care Needs to determine SCHIP eligibility and coverage in 2001 and 2005. In addition to descriptive analysis, a multilevel analysis was performed to identify personal and state-level factors that significantly affected uninsurance among the SCHIP-eligible CSHCN.

RESULTS

Our analyses showed that there was a slight increase in SCHIP eligibility for CSHCN between 2001 and 2005 (8.44% vs 9.83%; P < .05, chi(2) test). Among the SCHIP-eligible CSHCN, we found a substantial decrease in the uninsurance rate from 21.15% in 2001 to 10.87% in 2005 (P < .05, chi(2) test). After controlling for covariates, our analyses indicated that CSHCN in 2005 were 57% less likely to be uninsured than those in 2001. Our multilevel analysis also identified state policies that significantly affected uninsurance among the SCHIP-eligible CSHCN, including asset tests (positive effects) and presumptive eligibility (negative effects).

CONCLUSION

Our results show a dramatic decrease in the uninsurance rate among SCHIP-eligible CSHCN between 2001 and 2005.

Beyond Incrementalism? SCHIP and the politics of health reform

When Congress enacted the State Children's Health Insurance Program (SCHIP) in 1997, it was heralded as a model of bipartisan, incremental health policy. However, despite the program's achievements in the ensuing decade, SCHIP's reauthorization triggered political conflict, and efforts to expand the program stalemated in 2007. The 2008 elections broke that stalemate, and in 2009 the new Congress passed, and President Barack Obama signed, legislation reauthorizing SCHIP. Now that attention is turning to comprehensive health reform, what lessons can reformers learn from SCHIP's political adventures?

Uninsurance among children whose parents are losing Medicaid coverage: Results from a statewide survey of Oregon families

CONTEXT

Thousands of adults lost coverage after Oregon's Medicaid program implemented cost containment policies in March 2003. Despite the continuation of comprehensive public health coverage for children, the percentage of uninsured children in the state rose from 10.1 percent in 2002 to 12.3 percent in 2004 (over 110,000 uninsured children). Among the uninsured children, over half of them were likely eligible for public health insurance coverage.

RESEARCH OBJECTIVE

To examine barriers low-income families face when attempting to access children's health insurance. To examine possible links between Medicaid cutbacks in adult coverage and children's loss of coverage.

DATA SOURCE/STUDY SETTING

Statewide primary data from low-income households enrolled in Oregon's food stamp program.

STUDY DESIGN

Cross-sectional analysis. The primary predictor variable was whether or not any adults in the household recently lost Medicaid coverage. The main outcome variables were children's current insurance status and children's insurance coverage gaps.

DATA COLLECTION

A mail-return survey instrument was designed to collect information from a stratified, random sample of households with children presumed eligible for publicly funded health insurance programs.

PRINCIPAL FINDINGS

Over 10 percent of children in the study population eligible for publicly funded health insurance programs were uninsured, and over 25 percent of these children had gaps in insurance coverage during a 12-month period. Low-income children who were most likely to be uninsured or have coverage gaps were Hispanic; were teenagers older than 14; were in families at the higher end of the income threshold; had an employed parent; or had a parent who was uninsured. Fifty percent of the uninsured children lived in a household with at least one adult who had recently lost Medicaid coverage, compared with only 40 percent of insured children (p=.040). Similarly, over 51 percent of children with a recent gap in insurance coverage had an adult in the household who lost Medicaid, compared with only 38 percent of children without coverage gaps (p<.0001). After adjusting for ethnicity, age, household income, and parental employment, children living in a household with an adult who lost Medicaid coverage after recent cutbacks had a higher likelihood of having no current health insurance (OR 1.44, 95 percent CI 1.02, 2.04), and/or having an insurance gap (OR 1.79, 95 percent CI 1.36, 2.36).

CONCLUSIONS

Uninsured children and those with recent coverage gaps were more likely to have adults in their household who lost Medicaid coverage after recent cutbacks. Although current fiscal constraints prevent many states from expanding public health insurance coverage to more parents, states need to be aware of the impact on children when adults lose coverage. It is critical to develop strategies to keep parents informed regarding continued eligibility and benefits for their children and to reduce administrative barriers to children's enrollment and retention in public health insurance programs.

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.

The level of hospital charges and the income of the uninsured patient

It is a commonly held belief that full billed charges for hospital services, when submitted to uninsured patients, constitute such an extraordinary payment burden that hospitals' attempts to collect full payment are irrational. We examine that proposition with data on the joint distribution of hospital charges and uninsured incomes, guided by prevailing standards on the concept of ability-to-pay. We find that there is in fact a substantial intersection of charges and incomes in which full payment from the uninsured, or at least substantial partial payment, is a reasonable commercial expectation. When we quantify the estimated extent of charge collectability, we conclude that there is empirical support for current hospital collection practices.

State and national estimates of insurance coverage and health care utilization for adolescents with chronic conditions from the National Survey of Children's Health, 2003

PURPOSE

To examine health and insurance characteristics of adolescents with special health care needs (ASHCN), at state and federal levels.

METHODS

We used the National Survey of Children's Health 2003, a nationally representative sample of children in the United States, to study adolescents 14-17 years of age. We present descriptive statistics and regression analyses of adolescents with and without special health care needs, regarding measures of health care use and insurance coverage.

RESULTS

Approximately 22% of adolescents 14-17 years old have a special health care need. On average, ASHCN have one more annual office visit per year than their non-SHCN peers (p < .001). ASHCN report three times the rate of unmet medical needs compared to their non-SHCN peers (p < .001), despite higher rates of insurance coverage (94% vs. 88%, p < .001). Overall, 26.9% of ASHCN have public coverage. Nationally, more than half of those ASHCN with public coverage report incomes above 100% of the federal poverty level (FPL), which puts them at risk for losing coverage when they age into adulthood. Across states, proportions of ASHCN on public coverage and with incomes > 100% FPL range from 3.2% to 37.5%.

CONCLUSIONS

One in six ASHCN currently has public coverage with household income that would make them ineligible by income criteria for continuing public coverage as adults. It is imperative to examine insurance continuity and corresponding health outcomes for ASHCN as they transition from child to adult health care settings, and to evaluate options for policy interventions that can sustain health care coverage for this vulnerable population.

The impacts of the State Children's Health Insurance Program on children who enroll: findings from ten states

OBJECTIVE

Examine the extent to which enrollment in the State Children's Health Insurance Program (SCHIP) affects access to care and service use in 10 states that account for over 60 percent of all SCHIP enrollees.

DATA SOURCES/STUDY SETTING

Surveys of 16,700 SCHIP enrollees were conducted in 2002 as part of a congressionally mandated study. Three domains of SCHIP enrollees were included: (1) children who were recently enrolled in SCHIP, (2) those who had been enrolled in SCHIP for 5 months or more, and (3) those who had recently disenrolled from SCHIP. Response rates varied across states and domains but were clustered between 75 and 80 percent. Five different types of indicators were examined: (1) service use; (2) unmet need; (3) parental perceptions about being able to meet their child's health care needs; (4) presence and type of a usual source of care; and (5) provider communication and accessibility.

STUDY DESIGN

The experiences SCHIP enrollees have while on the program are compared with those a separate sample of children had before enrolling using a separate sample pretest and posttest design, controlling for observable characteristics of the children and their families.

DATA COLLECTION/EXTRACTION METHODS

The sample was drawn based on a list frame of SCHIP enrollees. The survey was administered in English and Spanish, by Computer-Assisted Telephone Interviewing (CATI). Field follow-up was used to locate families who could not be reached by telephone and these interviews were conducted by cellular telephone.

PRINCIPAL FINDINGS

SCHIP enrollment was found to improve access to care along a number of different dimensions, other things equal, particularly relative to being uninsured. Established SCHIP enrollees were more likely to receive office visits, preventive health and dental care, and specialty care, more likely to have a usual source for medical and dental care and to report better provider communication and accessibility, and less likely to have unmet needs, financial burdens, and parental worry associated with meeting their child's health care needs. The findings are robust with respect to alternative specifications and hold up for individual states and subgroups.

CONCLUSIONS

Enrollment in SCHIP appears to be improving children's access to primary health care services, which in turn is causing parents to have greater peace of mind about meeting their children's needs.

Children's eligibility and coverage: recent trends and a look ahead

We used data from the 1996-2005 Medical Expenditure Panel Survey to track changes in children's public insurance eligibility and coverage. During the 2001-2005 "postexpansion" period, eligibility was approximately constant, while public enrollment increased rapidly and uninsurance declined. Nevertheless, as of 2005, 62 percent of all uninsured children (5.5 million) continued to be eligible but not enrolled. We present detailed estimates of their characteristics by age, income, race/ethnicity, health status, and nativity/citizenship. We also examine the impact of potential changes in SCHIP income thresholds--both an expansion and a rollback--and estimate the number and characteristics of the children potentially affected.

Enrolling in Medicaid through the National School Lunch Program: outcome of a pilot project in California schools

California has several health insurance programs for children. However, the system for enrolling into these programs is complex and difficult to manage for many families. Express Lane Eligibility is designed to streamline the Medicaid (called Medi-Cal in California) enrollment process by linking it to the National School Lunch Program. If a child is eligible for free lunch and the parents consent, the program provides two months of presumptive eligibility for Medi-Cal and a simplified application process for continuation in Medi-Cal. For those who are ineligible, it provides a referral to other programs. An evaluation of Express Lane shows that while many children were presumptively enrolled, nearly half of the applicants were already enrolled in Medi-Cal. Many Express Enrolled children failed to complete the full Medi-Cal enrollment process. Few were referred to the State Children's Health Insurance Program or county programs. Express Lane is less useful as a broad screening strategy, but can be one of many tools that communities use to enroll children in health insurance.

The effect of new insurance coverage on the health status of low-income children in Santa Clara County

OBJECTIVE

To examine whether providing health insurance coverage to undocumented children affects the health of those children.

DATA SOURCES/STUDY SETTING

The data come from a survey of 1235 parents of enrollees in the new insurance program ("Healthy Kids") in Santa Clara County, California. The survey was conducted from August 2003 to July 2004.

STUDY DESIGN

Cross-sectional study using a group of children insured for one year as the study group (N=626) and a group of newly insured children as the comparison group (N=609). Regression analysis is used to adjust for differences in the groups according to a range of characteristics.

DATA COLLECTION

Parents were interviewed by telephone in either English or Spanish (most responded in Spanish). The response rate was 89 percent.

PRINCIPAL FINDINGS

The study group-who were children continuously insured by Healthy Kids for one year-were significantly less likely to be in fair/poor health and to have functional impairments than the comparison group of newly insured children (15.9 percent versus 28.5 percent and 4.5 percent versus 8.4 percent, respectively). Impacts were largest among children who enrolled for a specific medical reason (such as an illness or injury); indeed, the impact on functional limitations was evident only for this subgroup. The study group also had fewer missed school days than the comparison group, but the difference was significant only among children who did not enroll for a medical reason.

CONCLUSIONS

Health insurance coverage of undocumented children in Santa Clara County was associated with significant improvements in children's health status. The size of this association could be overstated, since the comparison sample included some children who enrolled because of an illness or other temporary health problem that would have improved even without insurance coverage. However, even after limiting the study sample to children who did not enroll for a medical reason, a significant association remained between children's reported health and their health coverage. We thus cautiously conclude that Healthy Kids had a favorable impact on children's health.

SCHIP at a crossroads: experiences to date and challenges ahead

As reauthorization of the State Children's Health Insurance Program (SCHIP) looms, we examine the program's first decade and identify changes needed so that SCHIP can better serve its target population. We conclude that by many objective standards, SCHIP has been a success, but the challenge will be to maintain and build upon that success. Critical issues include the level and structure of federal funding; the continued problem of uninsurance among low-income children; the lack of information on quality, access, and costs; and whether SCHIP can serve as the foundation for addressing broader health care needs among low-income families.

The stigma of public programs: does a separate S-CHIP program reduce it?

Previous studies suggest access to and satisfaction with care may be different for enrollees in S-CHIP and Medicaid, but it is unclear whether those differences are fully explained by socioeconomic characteristics of the enrollees. We analyze access and satisfaction of three groups of children: Medicaid enrolled, S-CHIP enrolled, and children who are income eligible for Medicaid but carry a card similar to the state's S-CHIP children's card. Both enrollees and providers may believe that these children are enrolled in S-CHIP despite the fact that reimbursement is through the state's Medicaid system. Results indicate that the same network of providers treat, or are perceived by families to treat, the three groups differently. They support the notion that some of the differences in satisfaction between S-CHIP and Medicaid enrollees are related to unmeasured characteristics (for example, income) of the families in the different programs, but that programmatic identity contributes substantially to differential care experience.

The impact of realized access to care on health-related quality of life: a two-year prospective cohort study of children in the California State Children's Health Insurance Program

OBJECTIVE

To examine the effect of realized access to care (problems getting care, access to needed care) on health-related quality of life (HRQOL) in the California State Children's Health Insurance Program.

STUDY DESIGN

This was a prospective cohort study (n = 4,925; 70.5% [3438] had complete data). Surveys were taken at enrollment and after 1 and 2 years in the program. Parents and children reported HRQOL (PedsQL 4.0 Generic Core Scales). Repeated-measures analysis accounted for within-person correlation and adjusted for baseline PedsQL, baseline realized access, race/ethnicity, language, chronic health condition, and having a regular physician.

RESULTS

Realized access to care during the prior year was related to HRQOL for each subsequent year. Foregone care and problems getting care were associated with decrements of 3.5 (P < .001) and 4.5 (P < .001) points for parent proxy-report PedsQL and with decrements of 3.2 (P < .001) and 4.4 (P < .001) points for child self-report PedsQL. Improved realized access resulted in higher PedsQL scores, continued realized access resulted in sustained PedsQL scores, and foregone care resulted in cumulative declines in PedsQL scores.

CONCLUSIONS

Realized access to care is associated with statistically significant and clinically meaningful changes in HRQOL in children enrolled in the California State Children's Health Insurance Program.

Dimensions of the local health care environment and use of care by uninsured children in rural and urban areas

OBJECTIVE

Despite concerted policy efforts, a sizeable percentage of children lack health insurance coverage. This article examines the impact of the health care safety net and health care market structure on the use of health care by uninsured children.

METHODS

We used the Medical Expenditure Panel Survey linked with data from multiple sources to analyze health care utilization among uninsured children. We ran analyses separately for children who lived in rural and urban areas and assessed the effects on utilization of the availability of safety net providers, safety net funding, supply of primary care physicians, health maintenance organization penetration, and the percentage of people who are uninsured, controlling for other factors that influence use.

RESULTS

Fewer than half of uninsured children had office-based visits to health care providers during the year, 8% of rural and 10% of urban children visited the emergency department at least once, and just over half of children had medical expenditures or charges during the year. Among uninsured children in rural areas, living closer to a safety net provider and living in an area with a higher supply of primary care physicians were positively associated with higher use and medical expenditures. In urban areas, the supply of primary care physicians and the level of safety net funding were positively associated with uninsured children's medical expenditures, whereas the percentage of the population that was uninsured was negatively associated with use of the emergency department.

CONCLUSIONS

Uninsured children had low levels of utilization over a range of different health care provider types and settings. The availability of safety net providers in the local area and the safety net's capacity to serve the uninsured influence access to care among children. Possible measures for ensuring access to health care among uninsured children include increasing the density of safety net providers in rural areas, enhancing funding for the safety net, and policies to increase primary care physician supply.

Predicting the adoption of electronic health records by physicians: when will health care be paperless?

OBJECTIVES

The purpose of this study was threefold. First, we gathered and synthesized the historic literature regarding electronic health record (EHR) adoption rates among physicians in small practices (ten or fewer members). Next, we constructed models to project estimated future EHR adoption trends and timelines. We then determined the likelihood of achieving universal EHR adoption in the near future and articulate how barriers can be overcome in the small and solo practice medical environment.

DESIGN

This study used EHR adoption data from six previous surveys of small practices to estimate historic market penetration rates. Applying technology diffusion theory, three future adoption scenarios, optimistic, best estimate, and conservative, are empirically derived.

MEASUREMENT

EHR adoption parameters, external and internal coefficients of influence, are estimated using Bass diffusion models.

RESULTS

All three EHR scenarios display the characteristic diffusion S curve that is indicative that the technology is likely to achieve significant market penetration, given enough time. Under current conditions, EHR adoption will reach its maximum market share in 2024 in the small practice setting.

CONCLUSION

The promise of improved care quality and cost control has prompted a call for universal EHR adoption by 2014. The EHR products now available are unlikely to achieve full diffusion in a critical market segment within the time frame being targeted by policy makers.

The State Children's Health Insurance Program

PURPOSE OF REVIEW

The State Children's Health Insurance Program expanded public health insurance to children who are ineligible for Medicaid yet unable to afford private health insurance. The program was a natural experiment, offering the opportunity to study the effects of expanding health insurance to a large population of children who would otherwise be uninsured. The State Children's Health Insurance Program is reviewed in the context of program goals, evaluation dimensions, past and current findings, and future directions. The studies and findings fall into five dimensions: (1) outreach/enrollment/uptake and profile of enrollees, (2) impact on insurance coverage and uninsured rates, (3) coverage dynamics, (4) impact on outcomes, and (5) costs.

RECENT FINDINGS

Older studies focused on outreach, enrollment, characteristics of enrollees, disenrollment, and coverage dynamics. Current studies report the impact of the program on outcomes--including access to care, quality, satisfaction, unmet need, and health outcomes--for the overall population of children and for vulnerable subgroups, including racial and ethnic minorities and children with chronic illness. A smaller number of studies address costs.

SUMMARY

The State Children's Health Insurance Program is evolving with demonstrated successes and areas for improvement. This information can enhance practicing pediatricians' understanding of barriers that face low-income children and families in seeking care for their children, can offer insight into what health insurance can and cannot do in terms of ameliorating those barriers, can provide insight into the prior experiences and current medical needs that a new enrollee in the program might have at the first visit to a practitioner, and can illuminate the challenges that low-income children and families may face in obtaining and maintaining health insurance coverage.

Effects of the State Children's Health Insurance Program Expansions on children with chronic health conditions

OBJECTIVE

To estimate the effects of the State Children's Health Insurance Program (SCHIP) expansions on insurance coverage, use of health care services, and access to care for children with chronic health conditions.

METHODS

The primary source of data was the National Health Interview Survey. Children with chronic health conditions were identified primarily through reported diagnoses of common chronic conditions (eg, asthma, attention-deficit disorder, mental retardation, Down syndrome, cerebral palsy, muscular dystrophy, sickle cell disease, diabetes, arthritis, heart disease) and on the presence of activity limitations caused by a health problem lasting at least 12 months. We examined changes in a broad array of outcomes for children with chronic health conditions who gained eligibility under SCHIP or who were already eligible for coverage under Medicaid, comparing the periods before and after implementation of the program. Changes for these treatment groups were compared with children with slightly higher incomes, who should not have been affected by the eligibility expansions. Comparisons were made with adjustment for child, family, and other characteristics that might have independent effects on the outcomes of interest. Outcomes included health insurance coverage, use of general and specialty services, access to care, and out-of-pocket spending on health care. Selected analyses were conducted for children not identified as having chronic health conditions.

RESULTS

The SCHIP expansions resulted in a 9.8 percentage point increase in the proportion of children with chronic conditions reporting public insurance and a 6.4 percentage point decline in the proportion uninsured. Unmet need for health care decreased by 8 percentage points, with most of the decline found for dental care. Increases in specialist, eye care, and dental visits and decreases in out-of-pocket spending and emergency-department and mental health visits were observed but did not meet standards of statistical significance. Estimated reductions in unmet need were greater for children with chronic conditions than for other children.

CONCLUSIONS

Recent expansions in public insurance eligibility under SCHIP have improved coverage for children with chronic conditions, with selected improvements in access to care. However, some eligible children with chronic conditions remain uninsured, and the impact on access to care and service use were limited. Additional progress may require targeted outreach to children with chronic conditions and improvements in Medicaid and SCHIP service-delivery systems. Given the current fiscal environment and the fact that children with chronic conditions have not generally been protected from cutbacks, the recent progress documented in this study may be reversed.

Children welcome, adults need not apply: changes in public program enrollment across states and over time

This article describes changes in the extent of public health insurance coverage for low-income children and adults from 1979 through 2001. Although previous research has demonstrated that public coverage among children has increased substantially during the past 20 years, our work shows that almost all of the increase has occurred among children in families with incomes between 100% and 200% of the federal poverty level (FPL), with little change among children in families with incomes below 100% of FPL. In contrast to the increase in public coverage among children, there has been virtually no change in the generosity of public programs for low-income adults. The overall stability of public coverage for adults masks substantial changes at the state level: public coverage for adults increased substantially in Tennessee, Vermont, Arizona, and other states that implemented Section 1115 Medicaid waivers, while declining in New York, California, and many Rust Belt states.
