PANDAS with catatonia: a case report. Therapeutic response to lorazepam and plasmapheresis.

This is a report of an 11-year-old, prepubertal boy with acute-onset urinary urgency and frequency, obsessions and compulsions related to urination, severe mood lability, inattention, impulsivity, hyperactivity, and intermittent periods of immobilization. Fever, cough, otitis, and sinusitis preceded neuropsychiatric symptoms. Antistreptolysin O and DNAse B antibody titers were elevated, and magnetic resonance imaging revealed bilateral diffuse caudate nuclei swelling. Plasmapheresis resulted in significant and rapid clinical improvement of obsessive-compulsive disorder symptoms and a simultaneous decrease in basal ganglia swelling, consistent with an immune-mediated pathophysiological process involving group A beta-hemolytic streptococci. Hyperactivity, impulsivity, and inattention improved with lorazepam, suggesting that the attention-deficit/hyperactivity disorder symptoms could be manifestations of catatonia.

Insurance gaps among vulnerable children in the United States, 1999-2001.

OBJECTIVE: To quantify the number of children who experience gaps in insurance coverage and to determine whether vulnerable subgroups of children experience noteworthy lapses in insurance coverage. METHODS: We analyzed nationally representative data from 24,149 children sampled in the 1999-2001 Medical Expenditure Panel Survey linked to the 1997-1999 National Health Interview Survey. Vulnerable subgroups of children included children with chronic conditions, those from ethnic/racial minorities, and those living in poverty. On the basis of cumulative annual monthly insurance coverage status, each child fell into 1 of 3 groups: continuous coverage, uninsured, or gaps in coverage. Using SAS-callable SUDAAN, we conducted multivariate ordinal logistic regression model to quantify the likelihood of having gaps in coverage for vulnerable subgroups of children. RESULTS: From 1999 to 2001, we found that >9 million American children annually had gaps in coverage and that 5 to 6 million children annually were uninsured for the entire year. Sixty percent of children experienced gaps of at least 4 months, and >40% of all publicly and privately insured children had coverage gaps. After accounting for relevant covariates, children with chronic conditions were just as likely as other children to have gaps in coverage or be uninsured; Hispanic children were most likely to have insurance gaps or be uninsured; and children from poor and near-poor families were 4 to 5 times more likely to have lapsed coverage than children from high-income families. Poverty and maternal education were the strongest factors associated with lapsed coverage. CONCLUSIONS: Unstable health insurance is an underrecognized problem for children, including those with chronic conditions. Because unstable insurance coverage can lead to inadequate health care utilization and poor child health outcomes, strategies to promote stable insurance coverage merit serious consideration.

Health expenditures for privately insured adults enrolled in managed care gatekeeping vs indemnity plans.

OBJECTIVES: We assessed the ability of managed care gatekeeping strategies (i.e., requiring a designated primary care provider to authorize referrals) to control health care costs in the mid-1990s. METHODS: We analyzed expenditure data from 8195 privately insured adults sampled in the nationally representative 1996 Medical Expenditure Panel Survey. Managed care gatekeeping plan enrollees included those in health maintenance organizations and other plans requiring a primary care gatekeeper. All others were considered indemnity plan enrollees. RESULTS: In 1996, total per capita annual health expenditures for adult gatekeeping enrollees were about $50 less than those of indemnity enrollees, primarily owing to lower out-of-pocket expenditures. After multivariate adjustment, mean per capita expenditures were approximately 6% lower for gatekeeping enrollees than for indemnity enrollees. CONCLUSIONS: In the private sector, gatekeeping strategies resulted in modest cost savings over indemnity plans.

Health care expenditures of immigrants in the United States: a nationally representative analysis.

OBJECTIVES: We compared the health care expenditures of immigrants residing in the United States with health care expenditures of US-born persons. METHODS: We used the 1998 Medical Expenditure Panel Survey linked to the 1996-1997 National Health Interview Survey to analyze data on 18398 US-born persons and 2843 immigrants. Using a 2-part regression model, we estimated total health care expenditures, as well as expenditures for emergency department (ED) visits, office-based visits, hospital-based outpatient visits, inpatient visits, and prescription drugs. RESULTS: Immigrants accounted for $39.5 billion (SE=$4 billion) in health care expenditures. After multivariate adjustment, per capita total health care expenditures of immigrants were 55% lower than those of US-born persons ($1139 vs $2546). Similarly, expenditures for uninsured and publicly insured immigrants were approximately half those of their US-born counterparts. Immigrant children had 74% lower per capita health care expenditures than US-born children. However, ED expenditures were more than 3 times higher for immigrant children than for US-born children. CONCLUSIONS: Health care expenditures are substantially lower for immigrants than for US-born persons. Our study refutes the assumption that immigrants represent a disproportionate financial burden on the US health care system.

The role of health insurance on Pap smear and mammography utilization by immigrants living in the United States.

BACKGROUND: Nearly half of recent immigrants to the United States lack health insurance. Access to cancer screening services for this group is problematic. We examine the role of health insurance and having a usual source of care (USC) on Pap smear and mammography utilization by immigrant women using a nationally representative sample. METHODS: We used a telephone survey that oversampled racial and ethnic minorities. We analyzed data on 3,622 women age 18-70. We classified the 822 foreign-born women as recent immigrants if they had resided in the United States for under 10 years; LT immigrants were those with a longer tenure. RESULTS: Among recent immigrants, 73% and 78% (SE 4%) reported a Pap smear or mammogram, respectively, in the previous 2 years versus 89% and 89% of U.S.-born women (P < 0.05 for both comparisons). Among those with insurance or a USC, differences in screening between recent immigrants and U.S.-born women were four percentage points or less and not statistically significant. However, uninsured recent immigrants were less likely than uninsured U.S.-born women to have Pap smears [60% (SE 7%) versus 71%, P < 0.05]. Adjusting for differences in sociodemographics, health attitudes or beliefs, patient or provider communication, and the medical care environment, insurance remained the strongest predictor of screening. CONCLUSION: Disparities in screening were greatly attenuated among the insured population. Increasing awareness of available safety net sources of care may also improve cancer screening among uninsured recent immigrants.

The generation gap: differences between children and adults pertinent to economic evaluations of health interventions.

Differences between children and adults have both technical and ethical implications for the design, interpretation and employment of economic analyses of health-related programmes. Even though policy makers increasingly turn to economic analyses to inform decisions about resource allocation, pertinent child-adult differences have received fragmented discussion in leading methodological references. Key areas warranting attention include: the ways in which a child's distinctive biology modifies the cost and effectiveness of healthcare interventions; challenges in assessing utilities for infants and young children given their limited but developing cognitive capacity; how a child's age, dependency and disability affect the selection of the appropriate time horizon and scope of the analysis; whether a child's non-wage earning productivity should be incorporated into analyses, and if so, what metric to use; what principles of equity policy makers should employ in using economic evaluations to choose between child- and adult-focused interventions; and whether special protective measures should be introduced to secure the rights and interests of children who cannot advocate for themselves.

Public spending on elders and children: the gap is growing.

Social welfare programs support the income, education, nutrition, and medical care needs of many of this country's elders and children. Over the past twenty years, however, three times as many children as elders have lived in poverty, and poverty rates for children have consistently exceeded those for the elderly. Given the continued disparity in poverty rates, it is important to track levels of public spending for each group and the generational balance in allocating limited public funds. This Issue Brief evaluates trends in social welfare spending for children and the elderly from 1980 to 2000, and the relationship of national economic trends to public spending patterns.

Does gatekeeping control costs for privately insured children? Findings from the 1996 medical expenditure panel survey.

OBJECTIVE: Gatekeeping requirements were widely adopted by health insurers in an attempt to control costs in the mid-1990s, but empirical evidence demonstrating decreased health expenditures for children enrolled in such plans is lacking. METHODS: We analyzed data from 3254 children with private health insurance sampled in the 1996 Medical Expenditure Panel Survey (MEPS) to compare total per capita health expenditures among gatekeeping versus indemnity plan enrollees. This sample represents 40.4 million privately insured American children. Total expenditures were defined as payments from all sources, including third-party and out-of-pocket payments, but excluding administrative costs. MEPS data are based on information provided by patients, health care providers, and hospitals. Gatekeeping plans included all children enrolled in health maintenance organizations or other plans requiring a primary care gatekeeper. All others were considered indemnity plan enrollees. RESULTS: Mean total per capita annual expenditures for children in gatekeeping versus indemnity plans differed by <1% (887 dollars vs 881 dollars, respectively). Third-party payments by gatekeeping plans on behalf of their beneficiaries were 636 dollars versus 595 dollars by indemnity plans. Out-of-pocket payments were on average 62 dollars less for gatekeeping enrollees than for indemnity enrollees. After multivariate adjustment, mean per capita expenditures were approximately 4% lower for gatekeeping enrollees than for indemnity enrollees. CONCLUSION: In 1996, total per capita annual health expenditures for children in gatekeeping plans were approximately 8 dollars less than for those in indemnity plans. These data indicate that gatekeeping is not an effective cost-containment method for children.

Gatekeeping and children's health care costs.

In the 1990's, primary care gatekeeping became a hallmark of managed care and a major model of health care delivery. Proponents claimed that gatekeeping--requiring that primary care providers preauthorize specialty visits--could control costs and improve coordination of care. However, much of this potential has remained unrealized, and managed care organizations are beginning to loosen these restrictions. This Issue Brief adds to the growing literature on the ineffectiveness of gatekeeping in controlling costs in pediatric care. The following study focuses on privately insured children, and analyzes the impact of gatekeeping on their health care expenditures.

Changes in use of health insurance and food assistance programs in medically underserved communities in the era of welfare reform: an urban study.

OBJECTIVES: The purpose of this study was to assess changes in health insurance and food assistance enrollment following passage of the Personal Responsibility and Work Opportunity Reconciliation Act of 1996. METHODS: Extant data sources were used to calculate changes in Temporary Assistance for Needy Families (TANF), Medicaid, and Food Stamp program enrollment in medically underserved Manhattan communities after 1996. RESULTS: Dramatic declines in TANF enrollment were accompanied by declines in Food Stamp program enrollment and a deceleration in Medicaid enrollment among several communities. CONCLUSIONS: As the Personal Responsibility and Work Opportunity Reconciliation Act comes up for reauthorization later in 2002, policymakers should revise legislation so that needy families do not lose health insurance or food assistance support.

A sampling bias in identifying children in foster care using Medicaid data.

BACKGROUND: Prior research identified foster care children using Medicaid eligibility codes specific to foster care, but it is unknown whether these codes capture all foster care children. OBJECTIVES: To describe the sampling bias in relying on Medicaid eligibility codes to identify foster care children. METHODS: Using foster care administrative files linked to Medicaid data, we describe the proportion of children whose Medicaid eligibility was correctly encoded as foster child during a 1-year follow-up period following a new episode of foster care. Sampling bias is described by comparing claims in mental health, emergency department (ED), and other ambulatory settings among correctly and incorrectly classified foster care children. RESULTS: Twenty-eight percent of the 5683 sampled children were incorrectly classified in Medicaid eligibility files. In a multivariate logistic regression model, correct classification was associated with duration of foster care (>9 vs <2 months, odds ratio [OR] 7.67, 95% confidence interval [CI] 7.17-7.97), number of placements (>3 vs 1 placement, OR 4.20, 95% CI 3.14-5.64), and placement in a group home among adjudicated dependent children (OR 1.87, 95% CI 1.33-2.63). Compared with incorrectly classified children, correctly classified foster care children were 3 times more likely to use any services, 2 times more likely to visit the ED, 3 times more likely to make ambulatory visits, and 4 times more likely to use mental health care services (P < .001 for all comparisons). CONCLUSIONS: Identifying children in foster care using Medicaid eligibility files is prone to sampling bias that over-represents children in foster care who use more services.

Generational differences in U.S. public spending, 1980-2000.

The balance between spending on children and spending on the elderly is important in evaluating the allocation of public welfare spending. We examine trends in public spending on social welfare programs for children and the elderly during 1980-2000. For both groups, social welfare spending as a percentage of gross domestic product changed little, even during the economic expansions of the 1990s. In constant dollars, the gap in per capita social welfare spending between children and the elderly grew 20 percent. Unlike spending for programs for the elderly, spending for children's programs suffered during recessions. Public discussion about the current imbalance in public spending is needed.
