The impact of managed care enrollment on emergency department use among children with special health care needs.

BACKGROUND: Many states recently have experimented with managed care as a way both to control costs and to enhance continuity of care in their publicly financed programs. A few states have applied managed care models to the care of chronically ill children. One marker for the effects of managed care is changes in use of the emergency department (ED). OBJECTIVE: We sought to determine whether a managed care program can reduce ED use for children with chronic health problems. SUBJECTS: We studied chronically ill children who were dually enrolled in Michigan's Title V program for children with special health care needs and Medicaid and who were enrolled in a managed care option at some time during the study period. The managed care model emphasized care coordination and did not include strong financial incentives for utilization and cost control. Sample consisted of 8580 person-months. METHOD: We used a fixed-effect negative binomial Poisson regression model to compare ED use before and after joining a managed care plan to test whether managed care use was associated with reduced likelihood of ED use. RESULTS: Managed care enrollment was associated with a 23% reduction in the incidence of ED use among children dually enrolled in Medicaid and Title V. CONCLUSIONS: A managed care model is associated with statistically significant and substantive reductions in observed use of ED care within an important population of children facing chronic illness.

Welfare receipt and substance-abuse treatment among low-income mothers: the impact of welfare reform.

OBJECTIVES: We explored changing relations between substance use, welfare receipt, and substance-abuse treatment among low-income mothers before and after welfare reform. METHODS: We examined annual data from mothers aged 18 to 49 years in the 1990-2001 National Household Survey of Drug Abuse and the 2002 National Survey of Drug Use and Health. Logistic regression was used to examine determinants of treatment receipt. RESULTS: Among low-income, substance-using mothers, the proportion receiving cash assistance declined from 54% in 1996 to 38% in 2001. The decline was much smaller (37% to 31%) among low-income mothers who did not use illicit substances. Low-income, substance-using mothers who received cash assistance were much more likely than other low-income, substance-using mothers to receive treatment services. Among 2002 National Survey of Drug Use and Health respondents deemed "in need" of substance-abuse treatment, welfare recipients were significantly more likely than nonrecipients to receive such services (adjusted odds ratio=2.31; P<.05). Controlling for other factors, welfare receipt was associated with higher prevalence of illicit drug use. Such use declined among both welfare recipients and other mothers between 1990 and 2001. CONCLUSIONS: Welfare is a major access point to identify and serve low-income mothers with substance-use disorders, but it reaches a smaller proportion of illicit drug users than it did prereform. Declining welfare receipt among low-income mothers with substance abuse disorders poses a new challenge in serving this population.

Outpatient substance abuse treatment and HIV prevention: an update.

Testing and counseling, along with community outreach, have been identified as valuable in the prevention of human immunodeficiency virus (HIV) and other blood-borne diseases. This article assesses the extent to which outpatient substance abuse treatment (OSAT) programs provide such services. Longitudinal data for 1988-2000 were analyzed from the National Drug Abuse Treatment System Survey (NDATSS). Random-effects regression was used to examine factors associated with the provision of prevention services. HIV testing, which had became more common between 1990 and 1995, continued to proliferate between 1995 and 2000. The proportion of units that provide HIV testing and counseling increased from 66% to 86%. The proportion of units that provide HIV community outreach increased significantly before 1995 but then slightly decreased from 77% to 73% between 1995 and 2000. In conclusion, HIV testing and counseling widely proliferated in OSAT care. However, OSAT units remain less likely to offer HIV community outreach services.

Changes in the timing of SIDS deaths in 1989 and 1999: indirect evidence of low homicide prevalence among reported cases.

An unknown proportion of cases diagnosed as sudden infant death syndrome (SIDS) are misdiagnosed, and in some cases are homicides. Because recent SIDS prevention measures were unlikely to reduce homicides, changes in the reported timing of SIDS cases provide an indirect measure of covert homicides in this group. This paper uses United States vital statistics microdata to explore these questions. The sample includes all reported infant deaths to singletons with birthweight > 500 g in the 1989 and 1999 US birth cohorts. Deaths attributed to SIDS (n = 7708), homicide (n = 597), or object inhalation and mechanical suffocation (n = 860) are specifically examined. If reported SIDS cases were a mixture of 'true' cases and misdiagnosed homicides, it is hypothesised that the age-at-death distribution of SIDS deaths would have changed to reflect greater prevalence of misdiagnosed homicide. We find that the age-at-death distribution of reported SIDS cases was virtually unchanged in the two cohorts, showing no increase during periods of infancy when relative homicide risk is most pronounced. One cannot reject the hypothesis that the timing was drawn from the same distribution (chi2(52)= 62.2, P = 0.157). Analogous results hold for infants born in circumstances associated with high homicide risk (chi2(50) = 61.5, P = 0.12). The stable age-at-death distribution of reported SIDS cases between 1989 and 1999 suggests that covert homicides are a small fraction of reported SIDS cases.

Duration of nonmethadone outpatient treatment: results from a national survey.

OBJECTIVES: This study examined organizational trends from 1990 to 2000 and unit characteristics associated with the duration of nonmethadone outpatient addiction treatment. METHODS: Program directors and clinical supervisors from a nationally representative panel of nonmethadone outpatient units in the United States were surveyed in 1990, 1995, and 2000. Treatment duration was measured from clinical supervisors' reports of the average length of stay. Negative binominal regression models controlled for multivariate effects. RESULTS: Treatment duration modestly declined between 1990 and 2000 while addiction severity increased. Affiliation with a mental health center, older program age, JCAHO accreditation-ostensibly a marker for structural quality-and serving more clients with prior authorization requirements- a measure of managed care stringency-were associated with shorter treatment durations. CONCLUSIONS: These findings suggest that treatment duration did not increase between 1990 and 2000 despite clients' worsening addiction severity and growing evidence that longer duration of formal treatment improves treatment outcome. In addition, programs with JCAHO accreditation and stronger managed care oversight appeared to seek efficiencies through reductions in treatment duration.

Welfare reform and substance abuse.

The 1996 Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) changed the nature, purpose, and financing of public aid. Researchers, administrators, and policymakers expressed special concern about the act's impact on low-income mothers with substance use disorders. Before PRWORA's passage, however, little was known about the true prevalence of these disorders among welfare recipients or about the likely effectiveness of substance abuse treatment interventions for welfare recipients. Subsequent research documented that substance abuse disorders are less widespread among welfare recipients than was originally thought and are less common than other serious barriers to self-sufficiency. This research also showed significant administrative barriers to the screening, assessment, and referral of drug-dependent welfare recipients. This article summarizes current research findings and examines implications for welfare reform reauthorization.

Emergency department use among Michigan children with special health care needs: an introductory study.

OBJECTIVE: To describe patterns of emergency department (ED) use among children dual-enrolled in Medicaid and Michigan's Children's Special Health Care Services (CSHCS). DATA SOURCES: Individual claims and enrollment data from Michigan's Medicaid and CSHCS programs for the period January 1, 1998, to June 30, 1999. Claims data were linked with eligibility data and then used to develop a 100 percent sample of claims for individuals enrolled in both Medicaid and CSHCS. STUDY DESIGN: Poisson regression analysis was used to examine the rate of ED use for dual-enrolled children. A time-varying hazard analysis was also used to examine the impact of changes over time. The key variables were gender, age, race, county of residence, Medicaid eligibility category, and qualifying diagnosis. PRINCIPAL FINDINGS: Dual-enrolled children under one year of age, and those with qualifying diagnoses of anemia, hemophilia, asthma, epilepsy, and juvenile diabetes displayed especially high rates of ED use. Significant geographic variation in ED use remained after controlling for qualifying diagnoses, race/ethnicity, and other factors. African Americans displayed higher rates of ED utilization than non-Hispanic whites. Supplemental Security Income (SSI) recipients demonstrated higher utilization than other groups. CONCLUSIONS: Children dually enrolled in CSHCS and Medicaid face diverse challenges of both poverty and chronic illness. Differences in patterns of use highlight the importance, but also the difficulty, of developing systems of care to manage complex chronic conditions in low-income populations.

Decrease in the prevalence of environmental tobacco smoke exposure in the home during the 1990s in families with children.

OBJECTIVES: This study explored correlates with and changes in the prevalence of environmental tobacco smoke (ETS) exposure of children in the home. METHODS: We used multiple logistic regression to explore ETS exposures as reported in the 1992 and 2000 National Health Interview Survey. RESULTS: ETS exposure in homes with children declined from 35.6% to 25.1% (P <.001) between 1992 and 2000, whereas smoking prevalence declined 26.5% to 23.3%. Home ETS exposures were more prevalent among non-Hispanic Whites than among African Americans (adjusted odds ratio [AOR] = 0.702; 95% confidence interval [CI] = 0.614, 0.802), Asian Americans (AOR = 0.534; 95% CI = 0.378, 0.754), and Hispanics (AOR = 0.388; 95% CI = 0.294, 0.389). Exposures declined across all groups, with greater gains in higher education and income groups. CONCLUSIONS: Home ETS exposure declined sharply between 1992 and 2000, more than would be predicted by the decline in adult smoking prevalence.

A birth records analysis of the Maternal Infant Health Advocate Service program: a paraprofessional intervention aimed at addressing infant mortality in African Americans.

Recognizing that no single intervention was likely to eliminate racial disparities, the Genesee County REACH 2010 partnership, utilizing both "bench" science and "trench" knowledge, developed 13 broad-based, multi-faceted interventions to eliminate infant mortality. This article provides highlights from a recent birth records comparison analysis of the Maternal Infant Health Advocate Service (MIHAS) intervention, and is solely based on the records of 111 MIHAS clients, and a random sample of 350 African-American women residing in Flint, Michigan. The MIHAS clients were more likely than the comparison sample not to have graduated from high school (56% vs 35%, respectively, P<.0001). The MIHAS clients were more likely to report at least some smoking during pregnancy (20% vs 15%, respectively, P<.05). However, after controlling for age and education, these results were no longer statistically significant. In terms of birth outcomes, the comparative odds of MIHAS clients delivering a low birth-weight infant are 1.124 (95% CI: 0.620-2.038); the odds of their delivering an infant at 37 weeks or earlier are 1.032 (0.609-1.749). Although the MIHAS clients did not have statistically better birth outcomes than those of the general African-American population in Flint, the MIHAS clients did not demonstrate the outcomes one would expect, given their higher level of risk. Based on this analysis, the MIHAS intervention may have brought its clients "up to par" with the general community on several birth outcomes.

Social marginalization of overweight children.

BACKGROUND: Overweight is the most common health problem that faces children and adolescents. Although the correlation among overweight, low self-esteem, and depression is well known, social isolation among overweight children and adolescents has not been studied. OBJECTIVE: To investigate social networks of overweight and normal-weight adolescents in a large, nationally representative sample. DESIGN: Cross-sectional, nationally representative cohort study. Population A total of 90 118 adolescents aged 13 to 18 years who were enrolled in the National Longitudinal Study of Adolescent Health, of which a 1:5 subsample was selected for detailed in-home assessment, including height and weight measurements (n = 17 557). Overweight was defined according to body mass index (>95th percentile for age and sex). MAIN OUTCOME MEASURES: This analysis focuses on the number of friendship nominations each adolescent received from other adolescents. The number of friendship nominations and other social network measures were calculated using statistical software. RESULTS: Overweight adolescents were more likely to be socially isolated and to be peripheral to social networks than were normal-weight adolescents. Although overweight adolescents listed similar numbers of friends as normal-weight adolescents, overweight adolescents received significantly fewer friendship nominations from others than were received by normal-weight adolescents (mean [SE] number of friendship nominations, 3.39 [0.08] vs 4.79 [0.04]; P<.001). Overweight adolescents were also more likely to receive no friendship nominations than were normal-weight adolescents (odds ratio, 1.71; 95% confidence interval, 1.39-2.20). Decreased television viewing (P<.001), increased levels of sports participation (P<.001), and increased participation in school clubs (P<.001) were associated with significantly more friendship nominations and higher network centrality scores among both overweight and normal-weight adolescents. CONCLUSIONS: Many overweight adolescents are socially marginalized. Such isolation may aggravate the social and emotional consequences of overweight in this age group.

Political economy of youth smoking regulation.

This paper considers the political economy of tobacco regulation-that is, the interplay between politics and markets in tobacco regulation. In surveying the interest-group politics of tobacco control, it describes political advantages held by a profitable and concentrated industry engaged in tobacco production. It also considers reasons for the surprising political success of tobacco control advocates over the past decade. The paper considers challenges faced by tobacco control advocates, who face their own obstacles to collective action in promoting effective tobacco regulation. Both public officials and tobacco control advocates face stronger incentives to advocate new legislation than they do to ensure effective implementation of existing regulatory measures. The essay concludes by considering the Master Settlement Agreement, whose detailed implementation remains uncertain after the election of the Bush administration.

Changes in methadone treatment practices: results from a national panel study, 1988-2000.

CONTEXT: Results from several studies conducted in the early 1990s showed that the majority of US methadone maintenance programs did not use treatment practices that met established standards for the care of heroin users. Effective treatment for heroin users is critical given the upsurge in heroin use and the continued role of injection drug use in the human immunodeficiency virus and hepatitis C epidemics. OBJECTIVES: To examine the extent to which US methadone maintenance treatment programs have made changes in the past 12 years to provide adequate methadone doses and to identify factors associated with variation in program performance. DESIGN, SETTING, AND PARTICIPANTS: Program directors and clinical supervisors of nationally representative methadone treatment programs that varied by ownership (for-profit, public, or private not-for-profit) and setting (eg, free-standing, hospital-based) were surveyed in 1988 (n = 172), 1990 (n = 140), 1995 (n = 116), and 2000 (n = 150). MAIN OUTCOME MEASURES: Percentage of patients in each treatment program receiving methadone dosages of less than 40, 60, and 80 mg/d. RESULTS: The percentage of patients receiving methadone dosage levels less than the recommended 60 mg/d has decreased from 79.5% in 1988 to 35.5% in 2000. Results also show that programs with a greater percentage of African American patients are especially likely to dispense low dosages, while programs with Joint Commission on Accreditation of Healthcare Organizations accreditation are more likely to provide adequate methadone doses. CONCLUSIONS: Efforts to improve methadone treatment practices appear to be making progress, but many patients are still receiving substandard care.

Position of the American Dietetic Association: nutrition services in managed care.

It is the position of the American Dietetic Association that medical nutrition therapy is an essential component of disease management and healthcare provided by managed care organizations, and that such care must be provided by qualified nutrition professionals. Compared with traditional fee-for-service reimbursement systems, managed care presents new opportunities for dietetics professionals. Until recently, the lack of billing infrastructure has handicapped nutrition providers who wish to bill for their services and has made it difficult to track the outcomes of nutrition care. With the publication of current procedure terminology codes for medical nutrition therapy (MNT) and the implementation of MNT benefits in Medicare part B for diabetes and nondialysis kidney disease, commercial payers, including managed care organizations (MCOs) are likely to implement or expand their coverage of MNT. A large body of evidence supports the efficacy and cost-effectiveness of MNT coverage within managed care plans. This evidence includes cost analyses of conditions treated by MNT, and clinical trial data confirming the efficacy of MNT in improving patient outcomes. MNT is also an important part of national standards of care for many chronic disease conditions. Based on evidence supporting the role of MNT in improving patient outcomes, the Institute of Medicine (IOM) recommended that MNT services be reimbursed by Medicare when patients are referred by a physician. Provision of appropriate MNT can also help MCOs meet accreditation and quality standards established by entities such as the National Committee for Quality Assurance and the Joint Commission for the Accreditation of Health Care Organizations. Much of the work required to secure a place for MNT in MCOs will be done at the practitioner level, by nutrition professionals themselves. Registered dietitians must market MNT to their customers in managed care by addressing the needs of each player. By emphasizing the importance of MNT and other cost-effective forms of preventive care and disease management, MCOs will be well positioned to improve population health at modest cost.

Infant sleep placement after the back to sleep campaign.

OBJECTIVES: The Back to Sleep campaign has been credited with recent declines in the incidence of sudden infant death syndrome. Using survey data for the 1996-1998 birth cohorts, this epidemiologic study examines infant sleep position in a large, population-based sample. DATA AND METHODS: Data concerning infant sleep position are drawn from the 1996-1998 Pregnancy Risk Assessment Monitoring System for 15 states. Weighted multiple logistic regression analysis is used to examine correlates of infant sleep position. RESULTS: The prevalence of prone infant sleeping significantly declined between 1996 and 1998 (adjusted odds ratio [AOR] = 0.70; 95% confidence interval [CI] = [0.63, 0.78]). African Americans were more likely than non-Hispanic whites to sleep prone, (AOR = 1.45; 95% CI = 1.33,1.59), and were less likely to sleep supine (AOR = 0.52; 95% CI = 0.48, 0.57). Hispanic/Latinos were less likely overall than non-Hispanic whites to sleep prone (AOR = 0.81; 95% CI = 0.69, 0.95), but were also less likely to sleep supine (AOR = 0.78; 95% CI = 0.69, 0.87). Adherence to sleep position recommended by the American Academy of Pediatrics increased sharply among Hispanic/Latino infants. Very low birth weight infants and infants in larger families were less likely to sleep in the recommended supine position. Infants born between 1001 and 1500 g (AOR = 0.67; 95% CI = 0.57, 0.79), and extremely low birth weight infants between 500 and 1000 g (AOR = 0.57; 95% CI = 0.45, 0.72) were especially unlikely to sleep supine. Infants in households with more than 3 other children (AOR = 1.72; 95% CI = 1.08, 2.74) were more likely to sleep prone. CONCLUSIONS: The prevalence of supine infant sleep increased between 1996 and 1998. Low adherence to sleep position recommendations of the American Academy of Pediatrics among African Americans, very low birth weight infants, and infants in large families remain public health concerns.

The impact of needle exchange-based health services on emergency department use.

OBJECTIVE: To examine the impact of the New Haven Community Health Care Van (CHCV), a mobile needle exchange-based health care delivery system, in reducing emergency department (ED) use among out-of-treatment injection drug users (IDUs) between January 1, 1996 and December 31, 1998. DESIGN: A pre-post comparison of ED utilization was performed using linked medical records from New Haven's only two emergency departments. Fixed-effect negative binomial regression analysis was used to explore the impact of the CHCV on ED use within a longitudinal cohort. SETTING: Mobile health clinic in New Haven, Conn. PARTICIPANTS: Out-of-treatment IDUs. INTERVENTION: Acute care, linkages to medical, drug treatment, and social services. MEASUREMENTS AND MAIN RESULTS: Among 373 IDUs, 117 (31%) were CHCV clients, and 256 had not used CHCV services. At baseline, CHCV users were more frequent users of ED services (P <.001). After full-scale implementation, mean ED utilization declined among CHCV clients and increased within the non-CHCV group. CHCV use is associated with statistically significant reductions in ED use, with an incidence rate ratio (IRR) of 0.79 (95% confidence interval [95% CI], 0.66 to 0.95). Subgroup analyses demonstrated significant IRR reductions, notably among Hispanics (0.65; 95% CI, 0.47 to 0.90), men (0.79; 95% CI, 0.64 to 0.98], HIV-negative IDUs (0.79; 95% CI, 0.63 to 0.98), and those with mental illness (0.75; 95% CI, 0.60 to 0.94). CONCLUSION: Needle exchange-based health care services can reduce ED utilization among high-risk injection drug users. Such services may have an important role within communities with high rates of drug use and HIV/AIDS.

Drug testing welfare recipients--false positives, false negatives, unanticipated opportunities.

Substance abuse and dependence are among the most common psychiatric disorders among pregnant and parenting women. These disorders among welfare recipients have attracted special concern. Chemical testing has been proposed to identify illicit drug use in this population. This analysis scrutinizes the potential value of drug testing, using recent data from the Women's Employment Study and the National Household Survey of Drug Abuse. One-fifth of recipients reported illicit substance use during the previous year. However, less than 5% satisfied diagnostic screening criteria for illicit drug dependence. Most recipients with psychiatric disorders or alcohol dependence reported no recent illicit drug use, and, thus, would not be detected through chemical tests. Although illicit drug users are rarely dependent, many face barriers to self-sufficiency. Screening and assessment programs should distinguish use from dependence, and should also identify alcohol dependence and psychiatric disorders. States should provide a range of treatment services to address these concerns.
