Accessibility of Medicare Diabetes Prevention Programs and Variation by State, Race, and Ethnicity

This cross-sectional study examines the accessibility of the Medicare Diabetes Prevention Program and investigates whether there are disparities in access among racial and ethnic minority beneficiaries at the state level.

State-Level Sexism and Women's Health Care Access in the United States: Differences by Race/Ethnicity, 2014-2019

Objectives. To quantify racial/ethnic differences in the relationship between state-level sexism and barriers to health care access among non-Hispanic White, non-Hispanic Black, and Hispanic women in the United States. Methods. We merged a multidimensional state-level sexism index compiled from administrative data with the national Consumer Survey of Health Care Access (2014-2019; n = 10 898) to test associations between exposure to state-level sexism and barriers to access, availability, and affordability of health care. Results. Greater exposure to state-level sexism was associated with more barriers to health care access among non-Hispanic Black and Hispanic women, but not non-Hispanic White women. Affordability barriers (cost of medical bills, health insurance, prescriptions, and tests) appeared to drive these associations. More frequent need for care exacerbated the relationship between state-level sexism and barriers to care for Hispanic women. Conclusions. The relationship between state-level sexism and women's barriers to health care access differs by race/ethnicity and frequency of needing care. Public Health Implications. State-level policies may be used strategically to promote health care equity at the intersection of gender and race/ethnicity.

Association of State-Level Medicaid Expansion With Treatment of Patients With Higher-Risk Prostate Cancer

IMPORTANCE

The Patient Protection and Affordable Care Act broadened insurance coverage, partially through voluntary state-based Medicaid expansion.

OBJECTIVE

To determine whether patients with higher-risk prostate cancer residing in Medicaid expansion states were more likely to receive treatment after expansion compared with patients in states electing not to pursue Medicaid expansion.

DESIGN, SETTING, AND PARTICIPANTS

This population-based cohort study included 15 332 patients diagnosed with higher-risk prostate cancer (ie, grade group >2; grade group 2 with prostate-specific antigen levels >10 ng/mL; or grade group 1 with prostate-specific antigen levels >20 ng/mL) from January 2010 to December 2016 aged 50 to 64 years who were candidates for definitive treatment. Patients residing in states that partially expanded Medicaid coverage before 2010 (ie, California and Connecticut) and those with diagnosis not confirmed by histology were excluded. Data were collected from the Surveillance, Epidemiology, and End Results Program. Data were analyzed between August and December 2019.

EXPOSURE

State-level Medicaid expansion status.

MAIN OUTCOMES AND MEASURES

Insurance status before and after expansion, treatment with prostatectomy or radiation therapy (including brachytherapy), treatment trends over time.

RESULTS

Of 15 332 patients, 7811 (50.9%) lived in expansion states (mean [SD] age, 59.1 [3.8] years; 5532 [71.9%] non-Hispanic White), and 7521 (49.1%) lived in nonexpansion states (mean [SD] age, 59.0 [3.9] years; 3912 [52.1%] non-Hispanic White). Residence in an expansion state was associated with higher pre-expansion levels of Medicaid coverage (292 [8.1%] vs 161 [3.8%]; odds ratio [OR], 2.12; 95% CI, 1.78 to 2.53) and lower likelihood of being uninsured (136 [3.2%] vs 38 [1.1%]; OR, 0.28; 95% CI, 0.15 to 0.54). After expansion, there was no difference in trends in treatment receipt between expansion and nonexpansion states (change, -0.39%; 95% CI, -0.11% to 0.28%; P = .25). Patients with private or Medicare coverage were more likely to receive treatment vs those with Medicaid or no coverage across racial/ethnic groups (eg, Black patients with coverage: OR, 2.30; 95% CI, 1.68 to 3.10; Black patients with no coverage: OR, 1.48; 95% CI, 1.09 to 2.00; P < .001). Medicaid patients were not more likely to be treated compared with those without insurance (737 [78.8%] vs 435 [79.5%]; OR, 0.97; 95% CI, 0.76 to 1.25).

CONCLUSIONS AND RELEVANCE

In this cohort study, state-level expansion of Medicaid was associated with increased Medicaid coverage for men with higher-risk prostate tumors but did not appear to affect treatment patterns at a population level. This may be related to the finding that Medicaid coverage was not associated with increased treatment rates compared with those without insurance.

Assessing the accuracy of survey reports of health insurance coverage using enrollment data

OBJECTIVE

To measure the accuracy of survey-reported data on features and type of health insurance coverage.

DATA SOURCE

Enrollment records from a private insurer were used as sample for primary survey data collection in spring of 2015 using the Current Population Survey health insurance module.

STUDY DESIGN

A reverse record check study where households with individuals enrolled in a range of public and private health insurance plans (including the marketplace) were administered a telephone survey that included questions about general source of coverage (eg, employer), program name (eg, Medicaid), portal, premium, and subsidies.

DATA COLLECTION/EXTRACTION METHODS

Survey data were matched back to enrollment records, which indicated coverage status at the time of the survey. Concordance between the records and survey data was assessed.

PRINCIPAL FINDINGS

Correct reporting of general source of coverage ranged from 77.8 percent to 98.3 percent across coverage type, premium ranged from 91.6 percent to 96.4 percent, and subsidy ranged from 83.0 percent to 91.0 percent. Using a conceptual algorithm to categorize coverage type resulted in sensitivity of 98.3 percent for employer-sponsored enrollees, and 70.6 percent-77.6 percent for the other coverage types, while specificity ranged from 93.9 percent to 99.4 percent across coverage types.

CONCLUSIONS

Survey reports of features of coverage suggest they are viable items to include in an algorithm to categorize coverage type. Findings have implications beyond the CPS, particularly for marketplace enrollees.

Association Between Health Plan Exit From Medicaid Managed Care and Quality of Care, 2006-2014

Importance

State Medicaid programs have increasingly contracted with insurers to provide medical care services for enrollees (Medicaid managed care plans). Insurers that provide these plans can exit Medicaid programs each year, with unclear effects on quality of care and health care experiences.

Objective

To determine the frequency and interstate variation of health plan exit from Medicaid managed care and evaluate the relationship between health plan exit and market-level quality.

Design, Setting, and Participants

Retrospective cohort of all comprehensive Medicaid managed care plans (N = 390) during the interval 2006-2014.

Exposures

Plan exit, defined as the withdrawal of a managed care plan from a state's Medicaid program.

Main Outcomes and Measures

Eight measures from the Healthcare Effectiveness Data and Information Set were used to construct 3 composite indicators of quality (preventive care, chronic disease care management, and maternity care). Four measures from the Consumer Assessment of Healthcare Providers and Systems were combined into a composite indicator of patient experience, reflecting the proportion of beneficiaries rating experiences as 8 or above on a 0-to-10-point scale. Outcome data were available for 248 plans (68% of plans operating prior to 2014, representing 78% of beneficiaries).

Results

Of the 366 comprehensive Medicaid managed care plans operating prior to 2014, 106 exited Medicaid. These exiting plans enrolled 4 848 310 Medicaid beneficiaries, with a mean of 606 039 beneficiaries affected by plan exits annually. Six states had a mean of greater than 10% of Medicaid managed care recipients enrolled in plans that exited, whereas 10 states experienced no plan exits. Plans that exited from a state's Medicaid market performed significantly worse prior to exiting than those that remained in terms of preventive care (57.5% vs 60.4%; difference, 2.9% [95% CI, 0.3% to 5.5%]), maternity care (69.7% vs 73.6%; difference, 3.8% [95% CI, 1.7% to 6.0%]), and patient experience (73.5% vs 74.8%; difference, 1.3% [95% CI, 0.6% to 1.9%]). There was no significant difference between exiting and nonexiting plans for the quality of chronic disease care management (76.2% vs 77.1%; difference, 1.0% [95% CI, -2.1% to 4.0%]). There was also no significant change in overall market performance before and after the exit of a plan: 0.7-percentage point improvement in preventive care quality (95% CI, -4.9 to 6.3); 0.2-percentage point improvement in chronic disease care management quality (95% CI, -5.8 to 6.2); 0.7-percentage point decrease in maternity care quality (95% CI, -6.4 to 5.0]); and a 0.6-percentage point improvement in patient experience ratings (95% CI, -3.9 to 5.1). Medicaid beneficiaries enrolled in exiting plans had access to coverage for a higher-quality plan, with 78% of plans in the same county having higher quality for preventive care, 71.1% for chronic disease management, 65.5% for maternity care, and 80.8% for patient experience.

Conclusions and Relevance

Between 2006 and 2014, health plan exit from the US Medicaid program was frequent. Plans that exited generally had lower quality ratings than those that remained, and the exits were not associated with significant overall changes in quality or patient experience in the plans in the Medicaid market.

Medicaid Community-Based Programs: A Longitudinal Analysis of State Variation in Expenditures and Utilization

As states face challenges posed by budget crises and pressures to develop Medicaid home and community-based services (HCBS), this paper provides a longitudinal analysis of state variation in expenditures and utilization for three HCBS programs (waivers, home health and personal care), and for total Medicaid HCBS. The first part of the analysis describes the nature and scope of state variation for each program in 1999, using such measures as participants per 1,000 population and expenditures per capita. The second part of the analysis presents time-series regression models that estimate sociodemographic, state policy, and market factors associated with intra-state variation in waiver participants and expenditures, and home health, personal care and total HCBS expenditures for the period 1992–99. Among the results, positive state-level factors related to HCBS participants and expenditures include: higher percentages of aged people, greater incomes per capita, and a larger supply of home health agencies.

The Impact of Local Welfare Offices on Children's Enrollment in Medicaid and SCHIP

Nearly 20% of children entering Kansas' State Children's Health Insurance Program (SCHIP) and more than 25% of children entering the state's Medicaid program leave public health insurance altogether before completing a full year of coverage, when the first redetermination of eligibility should occur. Analyses of administrative data indicate that high rates of premature disenrollment are strongly associated with case management practices at local social services offices. However, local offices enroll the vast majority of children into public health insurance. To avoid a potential trade-off between local offices' impact on enrollment and retention, the study suggests that states such as Kansas consider improvements in automation to support caseworkers' difficult jobs.

Algorithm development and the clinical and economic burden of Cushing's disease in a large US health plan database

PURPOSE

This study aimed to develop an algorithm to identify patients with CD, and quantify the clinical and economic burden that patients with CD face compared to CD-free controls.

METHODS

A retrospective cohort study of CD patients was conducted in a large US commercial health plan database between 1/1/2007 and 12/31/2011. A control group with no evidence of CD during the same time was matched 1:3 based on demographics. Comorbidity rates were compared using Poisson and health care costs were compared using robust variance estimation.

RESULTS

A case-finding algorithm identified 877 CD patients, who were matched to 2631 CD-free controls. The age and sex distribution of the selected population matched the known epidemiology of CD. CD patients were found to have comorbidity rates that were two to five times higher and health care costs that were four to seven times higher than CD-free controls.

CONCLUSION

An algorithm based on eight pituitary conditions and procedures appeared to identify CD patients in a claims database without a unique diagnosis code. Young CD patients had high rates of comorbidities that are more commonly observed in an older population (e.g., diabetes, hypertension, and cardiovascular disease). Observed health care costs were also high for CD patients compared to CD-free controls, but may have been even higher if the sample had included healthier controls with no health care use as well. Earlier diagnosis, improved surgery success rates, and better treatments may all help to reduce the chronic comorbidity and high health care costs associated with CD.

Health Care Utilization among Children Enrolled in Medicaid and CHIP via Express Lane Eligibility

OBJECTIVE

To assess health care utilization among children enrolled in Medicaid and CHIP via Express Lane Eligibility (ELE).

DATA SOURCES/STUDY SETTING

Enrollment, claims, and encounter data for children enrolled in Medicaid or CHIP in Alabama, Iowa, Louisiana, and New Jersey during 2009-2012.

STUDY DESIGN

We compared health care utilization among children enrolled via ELE and nondisabled children who enrolled through standard pathways in each state. We used a two-step estimation approach, examining the likelihood of utilization and then the volume and cost of services among users. Regression adjustment corrected for demographic differences.

PRINCIPAL FINDINGS

Most ELE and comparison group children used services within a year of enrollment and accessed a variety of services, including outpatient care, prescription drugs, and dental and vision care. ELE enrollees were somewhat less likely to use each service type, and those who used services often did so less intensively compared to other enrollees in their state.

CONCLUSIONS

Health care use patterns suggest that ELE enrollees are aware of their coverage; enrollees accessed and repeatedly used services covered by public health insurance. However, states considering this policy may expect that remaining eligible but uninsured children may be less expensive to cover than existing beneficiaries.

Institutional charges and disparities in outpatient brain biopsies in four US States: the State Ambulatory Database (SASD)

Several groups have demonstrated the safety of ambulatory brain biopsies, with no patients experiencing complications related to early discharge. Although they appear to be safe, the reasons factoring into the selection of patients have not been investigated. We performed a cross-sectional study involving 504 patients who underwent outpatient and 10,328 patients who underwent inpatient brain biopsies and were registered in State Ambulatory Surgery Databases and State Inpatient Databases respectively for four US States (New York, California, Florida, North Carolina). In a multivariate analysis private insurance (OR 2.45, 95 % CI, 1.85, 3.24), was significantly associated with outpatient procedures. Higher Charlson Comorbidity Index (OR 0.16, 95 % CI, 0.08, 0.32), high income (OR 0.37, 95 % CI, 0.26, 0.53), and high volume hospitals (OR 0.30, 95 % CI, 0.23, 0.39) were associated with a decreased chance of outpatient procedures. No sex, or racial disparities were observed. Institutional charges were significantly less for outpatient brain biopsies. There was no difference in the rate of 30-day postoperative readmissions among inpatient and outpatient procedures. The median charge for inpatient surgery was 51,316 as compared to 12,266 for the outpatient setting (P < 0.0001, Student's t test). Access to ambulatory brain biopsies appears to be more common for patients with private insurance and less comorbidities, in the setting of lower volume hospitals. Further investigation is needed in the direction of mapping these disparities in resource utilization.

The value of all-payer claims databases to states

All-payer claims databases are being developed in states across the nation to fill gaps in information about the health care system. The value of such databases is becoming more apparent as these databases mature and are used more frequently to help states better understand their health care utilization and costs.

What fraction of Medicaid enrollees have private insurance coverage at the time of enrollment? Estimates from administrative data

We use administrative data from Wisconsin to determine the fraction of new Medicaid enrollees who have private health insurance at the time of enrollment in the program. Through the linkage of several administrative data sources not previously used for research, we are able to observe coverage status directly for a large fraction of enrollees and indirectly for the remainder. We provide strict bounds for the percentages in each status and find that the percentage of new enrollees with private insurance coverage at the time of enrollment lies between 16 percent and 29 percent, and the percentage that dropped private coverage in favor of public insurance lies between 4 percent and 18 percent. Our point estimates indicate that, among all new enrollees, 21 percent had private health insurance at the time of enrollment and that 10 percent dropped this coverage. Our results show substantially lower rates than previous studies of crowd-out following public health insurance expansions and significant rates of dual coverage, whereby new enrollees into public insurance retain their previously held private insurance coverage.

Screening for impaired fasting glucose and diabetes using available health plan data

AIMS

To develop and validate prediction equations to identify individuals at high risk for type 2 diabetes using existing health plan data.

METHODS

Health plan data from 2005 to 2009 from 18,527 members of a Midwestern HMO without diabetes, 6% of whom had fasting plasma glucose (FPG) ≥110mg/dL, and health plan data from 2005 to 2006 from 368,025 members of a West Coast-integrated delivery system without diabetes, 13% of whom had FPG ≥110mg/dL were analyzed. Within each health plan, we used multiple logistic regression to develop equations to predict FPG ≥110mg/dL for half of the population and validated the equations using the other half. We then externally validated the equations in the other health plan.

RESULTS

Areas under the curve for the most parsimonious equations were 0.665 to 0.729 when validated internally. Positive predictive values were 14% to 32% when validated internally and 14% to 29% when validated externally.

CONCLUSION

Multivariate logistic regression equations can be applied to existing health plan data to efficiently identify persons at higher risk for dysglycemia who might benefit from definitive diagnostic testing and interventions to prevent or treat diabetes.

Clinical trial recruitment in rural South Carolina: a comparison of investigators' perceptions and potential participant eligibility

INTRODUCTION

Participation in clinical trial (CT) research can help decrease health disparities in rural communities. The purpose of this study was to examine the perceptions of principal investigators (PIs) regarding CT participation barriers and recruitment efforts in rural South Carolina, USA and to assess the actual pool of potential CT participants in rural and urban South Carolina. The ultimate goal was to evaluate the fit between PIs' perceptions and the pool of eligible participants in rural South Carolina.

METHODS

An online survey was conducted with 119 CT PIs from South Carolina's five main academic medical centers located in urban areas of the state, for a response rate of 31%. Secondary data analyses were also conducted using data from government health insurance plans, including the 2009 South Carolina Medicaid, the 2009 State Health Plan (SHP) data, and census data from the 2005-2009 American Community Survey (ACS). Both parametric and non-parametric statistics were used to analyze survey and secondary data.

RESULTS

Principal investigators perceived greater recruitment barriers in rural areas than in the general population. They indicated having difficulty finding CT participants in rural areas compared to the general population (t= -2.985, p=0.004). Rural residents were significantly more likely to be perceived as lacking knowledge and understanding about CT than the general public (t= -2.105, p=0.038), having significantly lower literacy than the general public (t= -2.058, p=0.043), lacking information about available CTs (t= -2.913, p=0.005), and having limited accessibility to trial sites compared to the general population (t= -4.380, p=0.000). Patients' insurance coverage, however, was not found to be a significant barrier for CT participation (t=0.418, p=0.677). Secondary data variables were aligned with these barriers. Data revealed that rural residents have slightly lower educational attainment than urban citizens >t=5.384, p=0.000), and more people live below poverty level in rural areas (23%) than in urban areas (15%) (t=4.86, p=0.000). The secondary data analyses also showed that the majority of rural citizens covered by the SHP and Medicaid are eligible for CTs. ACS data revealed that 75% of people in rural areas meet one or more basic eligibility requirements to participate in CTs compared to 83% in urban areas.

CONCLUSIONS

Some important barriers hinder CT enrollment of rural participants, such as accessibility to trial sites, poverty, lack of knowledge about CTs, among others. Data suggested that insurance coverage, however, is not a barrier to CT participation. Although CT PIs are correct in considering these barriers in rural areas, there still exists a large pool of potentially eligible CT participants in rural South Carolina. PIs, who were recruited from urban academic medical centers, may therefore be perpetuating unhelpful rural myths about CT eligibility in rural communities. Despite their remote locations, rural citizens should take part in medical research. Greater communication between PIs and rural participants and better education of PIs on communication strategies are needed to enhance CT participation in rural South Carolina.

States with the least restrictive regulations experienced the largest increase in patients seen by nurse practitioners

The use of nurse practitioners (NPs) is one way to address the shortage of physician primary care providers. NP training programs and the number of practicing NPs have increased in the past two decades. However, regulations limiting their scope of practice vary greatly by state. We assessed the impact of state regulations on the increase in care provided by NPs in the United States, using a 5 percent national sample of Medicare beneficiaries. We found that between 1998 and 2010 the number of Medicare patients receiving care from NPs increased fifteenfold. By 2010 states with the least restrictive regulations of NP practice had a 2.5-fold greater likelihood of patients' receiving their primary care from NPs than did the most restrictive states. Relaxing state restrictions on NP practice should increase the use of NPs as primary care providers, which in turn would reduce the current national shortage of primary care providers.

Insurance expansion in Massachusetts did not reduce access among previously insured Medicare patients

Critics of Massachusetts's health reform, a model for the Affordable Care Act, have argued that insurance expansion probably had a negative spillover effect leading to worse outcomes among already insured patients, such as vulnerable Medicare patients. Using Medicare data from 2004 to 2009, we examined trends in preventable hospitalizations for conditions such as uncontrolled hypertension and diabetes--markers of access to effective primary care--in Massachusetts compared to control states. We found that after Massachusetts's health reform, preventable hospitalization rates for Medicare patients actually decreased more in Massachusetts than in control states (a reduction of 101 admissions per 100,000 patients per quarter compared to a reduction of 83 admissions). Therefore, we found no evidence that Massachusetts's insurance expansion had a deleterious spillover effect on preventable hospitalizations among the previously insured. Our findings should offer some reassurance that it is possible to expand access to uninsured Americans without negatively affecting important clinical outcomes for those who are already insured.

Association between perinatal medical expenses and a waiver to increase Florida healthy start services within Florida medicaid programs: 1998 to 2006

To assess the association between perinatal care expenditures and a Medicaid waiver to increase Florida Healthy Start services among Florida Medicaid non-managed care organization (non-MCO) program enrollees. We assessed perinatal care expenditures from Medicaid claims and encounter data among non-MCO enrollees with increased risk pregnancies who gave birth in Florida during 1998-2006. We used a pre-post design to compare adjusted perinatal medical expenditures among women who received Healthy Start care coordination (n = 41,067) to women who were not contacted by the Healthy Start program after screening (n = 24,282). We calculated adjusted average costs and difference-in-differences using marginal estimates from multivariable linear mixed regression models. From the pre-waiver (January 1998-July 2001) to the late-post waiver (July 2004-December 2006), all prenatal medical costs increased $274 among care coordination participants and decreased $601 among women not contacted by the Healthy Start program, equaling a $875 increased cost difference between care coordination and no contact groups. During this same time period, delivery related expenditures increased $395 less among care coordination participants compared to women not contacted by Healthy Start. Additionally, infant medical care costs during days 29-365 decreased by an average of $240 less among the care coordination compared to the no contact group. The Medicaid waiver may have decreased delivery costs, but medical costs were increased following the waiver when considering all perinatal care. Further exploration of factors associated with the decreased delivery costs may help develop more efficient prenatal support programs.

Medication adherence and fracture risk among patients on bisphosphonate therapy in a large United States health plan

The association between bisphosphonate adherence in the first 12 months after therapy initiation and subsequent fracture risk was examined. Patients were identified from a large, commercially-insured population with integrated pharmacy and medical claims. Eligible patients were aged ≥45 years, were new to osteoporosis therapy (no osteoporosis medication claims in prior year) with first (index) bisphosphonate claim between 1/1/2005 and 4/30/2008, and had continuous insurance coverage for ≥12 months pre- and post-index. Patients with fracture claims ≤12-months post-index were excluded. Adherence was assessed using the medication possession ratio (MPR) over 12-months post-index (i.e., sum of days' supply dispensed divided by 365 days). Patients with a MPR>0.8 were considered adherent. The follow-up period to assess incident fracture began at month 13. The analysis included 33,558 new bisphosphonate users with mean age (SD) 59.5 (9.3) years; 94.0% were female. Median MPR at 12 months was 0.61 for alendronate and risedronate; 0.58 for ibandronate. Proportionally more nonfracture patients (39.3%) had a MPR>0.8 compared with fracture patients (34.9%, p<0.001). In multivariate modeling of bisphosphonate users' experience, those with a MPR>0.8 had a 14% lower risk of subsequent fracture than those with MPR<0.5, after controlling for demographics, insurance type, select comorbidities, and other potential confounders (p=0.0459). In a large, commercially-insured population, suboptimal adherence with bisphosphonate treatment was associated with increased fracture risk even after controlling for potential confounders.

Effects of a cost-sharing policy on disenrollment from a state health insurance program

Subsidized public health insurance programs face financial difficulties and are increasingly implementing policies to pass on greater costs to low-income enrollees. Results of a stratified, random sample of 1,153 enrollees and disenrollees of a state program after introduction of increased cost sharing revealed three main reasons for disenrollment, which varied by enrollee income: finding other coverage, becoming financially ineligible, or dropping coverage as too expensive. Seventeen percent of disenrollees cited cost sharing as a reason for disenrollment. Persons who disenrolled were more likely to be younger adults, male, and have fewer children. Persons who disenrolled reported greater subsequent out-of-pocket costs, more difficulty providing coverage for children, and less access to care than persons who stayed enrolled. Most enrollees stayed enrolled despite the cost sharing increases, and persons who did disenroll left for a variety of reasons, only one of which was cost. Implications for state health insurance policies are discussed.

The individual and program impacts of eliminating Medicaid dental benefits in the Oregon Health Plan

OBJECTIVES

We determined how elimination of dental benefits among adult Medicaid beneficiaries in Oregon affected their access to dental care, Medicaid expenditures, and use of medical settings for dental services.

METHODS

We used a natural experimental design using Medicaid claims data (n = 22 833) before and after Medicaid dental benefits were eliminated in Oregon in 2003 and survey data for continuously enrolled Oregon Health Plan enrollees (n = 718) covering 3 years after benefit cuts.

RESULTS

Claims analysis showed that, compared with enrollees who retained dental benefits, those who lost benefits had large increases in dental-related emergency department use (101.7%; P < .001) and expenditures (98.8%; P < .001) and in all ambulatory medical care use (77.0%; P < .01) and expenditures (114.5%; P < .01). Survey results indicated that enrollees who lost dental benefits had nearly 3 times the odds (odds ratio = 2.863; P = .001) of unmet dental need, and only one third the odds (odds ratio = 0.340; P = .001) of getting annual dental checkups relative to those retaining benefits.

CONCLUSIONS

Combined evidence from both analyses suggested that the elimination of dental benefits resulted in significant unmet dental health care needs, which led to increased use of medical settings for dental problems.

How have state policies to expand dependent coverage affected the health insurance status of young adults?

RESEARCH OBJECTIVE

Nearly one in three adults of ages 19-29 lack health insurance, representing the highest uninsured rate of any age group. To help address this gap, 38 states have enacted laws requiring insurers to permit young adults to enroll as dependents on their parents' plans. This paper evaluates their impact on coverage for young adults.

STUDY DESIGN/METHODS/DATA

This study uses data for individuals ages 19-29 from the Current Population Survey's Annual Demographic Supplement for calendar years 2000-2008. Linear probability models are used to obtain difference-in-differences estimates of the impact of dependent coverage expansions in 19 early-adopting states on young adults' insurance status. The models also address possible policy endogeneity due to the nonrandom enactment of expansion policies across states.

PRINCIPAL FINDINGS

State young adult dependent coverage policies yielded small increases in dependent coverage ranging from 1.52 percentage points for all young adults to 3.84 percentage points for those ages 19-25 residing with parents. These increases were largely offset by declines in employer-sponsored insurance (ESI) in the young adults' own name. No significant impact on young adult uninsured rates was observed.

CONCLUSIONS AND IMPLICATIONS

Adult dependent coverage expansions have had a relatively small impact on enrollment as an ESI dependent and appear to have the unintended consequence of reducing ESI policyholder coverage. This policy did not achieve a reduction in uninsured rates as policy makers had intended. Federal reform efforts to expand dependent coverage are likely to be more successful because reform will be accompanied by subsidies and enrollment mandates.

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.

Impact of state mandatory insurance coverage on the use of diabetes preventive care

BACKGROUND

46 U.S. states and the District of Columbia have passed laws and regulations mandating that health insurance plans cover diabetes treatment and preventive care. Previous research on state mandates suggested that these policies had little impact, since many health plans already covered the benefits. Here, we analyze the contents of and model the effect of state mandates. We examined how state mandates impacted the likelihood of using three types of diabetes preventive care: annual eye exams, annual foot exams, and performing daily self-monitoring of blood glucose (SMBG).

METHODS

We collected information on diabetes benefits specified in state mandates and time the mandates were enacted. To assess impact, we used data that the Behavioral Risk Factor Surveillance System gathered between 1996 and 2000. 4,797 individuals with self-reported diabetes and covered by private insurance were included; 3,195 of these resided in the 16 states that passed state mandates between 1997 and 1999; 1,602 resided in the 8 states or the District of Columbia without state mandates by 2000. Multivariate logistic regression models (with state fixed effect, controlling for patient demographic characteristics and socio-economic status, state characteristics, and time trend) were used to model the association between passing state mandates and the usage of the forms of diabetes preventive care, both individually and collectively.

RESULTS

All 16 states that passed mandates between 1997 and 1999 required coverage of diabetic monitors and strips, while 15 states required coverage of diabetes self management education. Only 1 state required coverage of periodic eye and foot exams. State mandates were positively associated with a 6.3 (P = 0.04) and a 5.8 (P = 0.03) percentage point increase in the probability of privately insured diabetic patient's performing SMBG and simultaneous receiving all three preventive care, respectively; state mandates were not significantly associated with receiving annual diabetic eye (0.05 percentage points decrease, P = 0.92) or foot exams (2.3 percentage points increase, P = 0.45).

CONCLUSIONS

Effects of state mandates varied by preventive care type, with state mandates being associated with a small increase in SMBG. We found no evidence that state mandates were effective in increasing receipt of annual eye or foot exams. The small or non-significant effects might be attributed to small numbers of insured people not having the benefits prior to the mandates' passage. If state mandates' purpose is to provide improved benefits to many persons, policy makers should consider determining the number of people who might benefit prior to passing the mandate.

Profile of the first 1,400 patients receiving diagnostic evaluations for fetal alcohol spectrum disorder at the Washington State Fetal Alcohol Syndrome Diagnostic & Prevention Network

BACKGROUND

An interdisciplinary approach to fetal alcohol spectrum disorder (FASD) diagnosis using rigorously defined diagnostic guidelines has been adopted as best practice. Diagnostic clinics are being established worldwide. If these clinics are to successfully compete for limited health care dollars, it is essential to document their value.

OBJECTIVE

The primary objectives were to document the value of the largest and longest standing interdisciplinary FASD diagnostic program; the Washington State Fetal Alcohol Syndrome Diagnostic & Prevention Network (WA FAS DPN). Now in its 17th year of operation, the WA FAS DPN is a statewide network of diagnostic clinics all using the 4-Digit Diagnostic Code and contributing to a centralized electronic database.

METHODS

The clinical database was used to generate comprehensive profiles of all patients evaluated for FASD from 1993-2005. These profiles were used to answer a multitude of clinical, research, and public health questions including: What is the demand for FASD diagnostic services, who is referred to the clinics, and what are their FASD diagnostic outcomes? Can FAS/D prevalence estimates from this clinical population be used to estimate FAS/D prevalence estimates in the general population? Do FASD diagnostic outcomes vary by race, age or alcohol exposure? Does the presence of other adverse exposures/events lead to more severe outcomes? Does this approach to diagnosis meet the needs of families?

RESULTS

Demand for diagnosis remains very high. Of 1,400 patients (newborn to adult) with confirmed prenatal alcohol exposure, 11% were diagnosed with FAS/PFAS, 28% with static encephalopathy, 52% with neurobehavioral disorder, and 9% with no evidence of CNS abnormality. FASD outcomes varied significantly by age, race, gender, alcohol exposure, and presence of other risk factors. Families reported high satisfaction with the diagnostic process, and receipt of information/services they were unable to obtain elsewhere.

CONCLUSIONS

This report documents the immense contribution of a statewide FASD diagnostic program, and underscores the extraordinary value of a comprehensive FASD clinical dataset.

Uncertain health insurance coverage and unmet children's health care needs

BACKGROUND AND OBJECTIVES

The State Children's Health Insurance Program (SCHIP) has improved insurance coverage rates. However, children's enrollment status in SCHIP frequently changes, which can leave families with uncertainty about their children's coverage status. We examined whether insurance uncertainty was associated with unmet health care needs.

METHODS

We compared self-reported survey data from 2,681 low-income Oregon families to state administrative data and identified children with uncertain coverage. We conducted cross-sectional multivariate analyses using a series of logistic regression models to test the association between uncertain coverage and unmet health care needs.

RESULTS

The health insurance status for 13.2% of children was uncertain. After adjustments, children in this uncertain "gray zone" had higher odds of reporting unmet medical (odds ratio [OR] =1.73; 95% confidence interval [CI]=1.07, 2.79), dental (OR=2.41; 95% CI=1.63, 3.56), prescription (OR=1.64, 95% CI=1.08, 2,48), and counseling needs (OR=3.52; 95% CI=1.56, 7.98), when compared with publicly insured children whose parents were certain about their enrollment status.

CONCLUSIONS

Uncertain children's insurance coverage was associated with higher rates of unmet health care needs. Clinicians and educators can play a role in keeping patients out of insurance gray zones by (1) developing practice interventions to assist families in confirming enrollment and maintaining coverage and (2) advocating for policy changes that minimize insurance enrollment and retention barriers.

The revolving door of rehospitalization from skilled nursing facilities

Almost one-fourth of Medicare beneficiaries discharged from the hospital to a skilled nursing facility were readmitted to the hospital within thirty days; this cost Medicare $4.34 billion in 2006. Especially in an elderly population, cycling into and out of hospitals can be emotionally upsetting and can increase the likelihood of medical errors related to care coordination. Payment incentives in Medicare do not encourage providers to coordinate beneficiaries' care. Revising these incentives could achieve major savings for providers and improved quality of life for beneficiaries.

Managed care quality and disenrollment in New York SCHIP

BACKGROUND

During the past decade, experts have devoted substantial efforts to quality improvement for managed care. Although a handful of studies have examined the effect of quality on enrollment, few have systematically investigated the association between managed care quality and plan disenrollment, especially among lowincome populations.

OBJECTIVE

To examine whether higher-quality measures in managed care plans are associated with lower disenrollment from the State Children's Health Insurance Program (SCHIP) in New York State.

DESIGN, SETTING, AND PARTICIPANTS

Observational study of managed care plan disenrollment for a New York statewide cohort of 2206 new SCHIP enrollees.

MEASUREMENTS

Managed care quality was measured by 7 Consumer Assessment of Health Plans Survey (CAHPS) scores and 3 Healthcare Effectiveness Data and Information Set (HEDIS) scores, obtained from the 2002 New York State Managed Care Plan Performance Report. Disenrollment was defined as being disenrolled from an SCHIP plan for 2 or more consecutive months based on the New York SCHIP universal billing files.

RESULTS

Nearly 40% of children were disenrolled during the study period. No overall effects of plan quality on disenrollment were detected, but plans with higher scores in "preventive care visits" had a significantly lower disenrollment rate. The disenrollment rate in the eligibility recertification period was 3.2 percentage points higher than that in other time periods.

CONCLUSION

Disenrollment was not associated with overall managed care plan quality as measured by CAHPS and HEDIS, suggesting that further study is warranted to determine optimal strategies for enhancing managed care quality in the SCHIP population.

Tobacco control policy and adolescent cigarette smoking status in the United States

INTRODUCTION

Tobacco policies that limit the sale of cigarettes to minors and restrict smoking in public places are important strategies to deter youth from accessing and consuming cigarettes.

METHODS

We examined the relationship of youth cigarette smoking status to state-level youth access and clean indoor air laws, controlling for sociodemographic characteristics and cigarette price. Data were analyzed from the 2001 to 2002 U.S. Health Behavior in School-Aged Children survey, a cross-sectional survey conducted with a nationally representative sample of 13,339 students in the United States.

RESULTS

Compared with students living in states with strict regulations, those living in states with no or minimal restrictions, particularly high school students, were more likely to be daily smokers. These effects were somewhat reduced when logistic regressions were adjusted for sociodemographic characteristics and cigarette price, suggesting that higher cigarette prices may discourage youth to access and consume cigarettes independent of other tobacco control measures.

DISCUSSION

Strict tobacco control legislation could decrease the potential of youth experimenting with cigarettes or becoming daily smokers. The findings are consistent with the hypothesis that smoking policies, particularly clean indoor air provisions, reduce smoking prevalence among high school students.

Linking mother and child access to dental care

OBJECTIVES

Among young children in low-income families covered by Medicaid, we estimated (according to racial/ethnic group) whether children who have mothers with a regular source of dental care at baseline have greater dental use in the subsequent year than children with mothers without a regular source.

METHODS

From a population of 108151 children (aged 3 to 6 years) who were enrolled in Medicaid and their low-income mothers in Washington state, a disproportionate stratified random sample of 11305 children aged 3 to 6 was selected from enrollment records in 4 racial/ethnic groups: black (3791), Hispanic (2806), white (1902), and other racial/ethnic groups (2806). In a prospective cohort design, we conducted a baseline survey of mothers and for respondents collected their children's Medicaid dental claims in the 1-year follow-up period. Mutivariable regression models estimated the associations between the mothers' having a regular source of dental care at baseline and their children's prospective dental use.

RESULTS

Approximately 38% of the mothers had a regular source of dental care. Among children of black and Hispanic mothers, having a mother with a regular source of dental care at baseline was associated with greater odds of receiving any dental care in the subsequent year. For children with dental use, children of black or Hispanic mothers with a regular source of dental care received 1.22 and 1.10 more preventive services, respectively. For children of white mothers, associations were in the same direction but not significant.

CONCLUSIONS

For young children of black and Hispanic mothers, dental care use is higher when their mothers have a regular source of dental care. For low-income young children with Medicaid, increasing the mothers' access to dental care may increase the children's use of dental and preventive services, which, in turn, may reduce racial/ethnic inequalities in oral health.

State, regional, and national estimates of health insurance coverage for people under 65 years of age: National Health Interview Survey, 2004-2006

OBJECTIVES

This report presents state, regional, and national estimates of the percentages of persons under 65 years of age who were uninsured, who had private health insurance coverage, and who had Medicaid or State Children's Health Insurance Program (SCHIP) coverage.

METHODS

The estimates were derived from the Family Core component of the 2004-2006 National Health Interview Survey (NHIS). Three years of data were combined to increase the reliability of estimates. Regional and national estimates are based on data from all 50 states and the District of Columbia. State estimates are shown for the 41 states with at least 1000 NHIS respondents during 2004-2006. Differences between national and subnational estimates were tested for statistical significance to identify those regions and states that differ significantly from the U.S. overall.

RESULTS

The results show that the percentage of persons under age 65 who lacked any insurance coverage at a point in time varied by 20 percentage points among the states. Almost all states that were significantly higher than the U.S. rate on the percentage uninsured were significantly lower than the U.S. rate on the percentage with private coverage and vice versa.

Trends in charges and payments for nonhospitalized emergency department pediatric visits, 1996-2003

OBJECTIVES

To compare charges and payments for outpatient pediatric emergency visits across payer groups to provide information on reimbursement trends.

METHODS

Total charges and payments for emergency department (ED) visits Medicaid/State Children's Health Insurance Program (SCHIP), privately insured, and uninsured pediatric patients from 1996 to 2003 using data from the Medical Expenditure Panel Survey. Average charges per visit and average payments per visit were also tracked, using regression analysis to adjust for changes in patient characteristics.

RESULTS

While charges for pediatric ED visits rose over time, payments did not keep pace. This led to a decrease in reimbursement rates from 63% in 1996 to 48% in 2003. For all years, Medicaid/SCHIP visits had the lowest reimbursement rates, reaching 35% in 2003. The proportion of visits from children insured by Medicaid/SCHIP also increased over the period examined. In 2003, after adjustment, charges were $792 per visit from children covered by Medicaid/SCHIP, $913 for visits from uninsured children, and $952 for visits from privately insured children.

CONCLUSIONS

Reimbursements for outpatient ED visits in the pediatric population have decreased from the period of 1996 to 2003 in all payer groups: public (Medicaid/SCHIP), private, and the uninsured. Medicaid/SCHIP has consistently paid less per visit than the privately insured and the uninsured. Further research on the effects of these declining reimbursements on the financial viability of ED services for children is warranted.

Data needs for policy research on state-level health insurance markets

Private and public health insurance provision in the United States operates against a backdrop of 50 different regulatory environments in addition to federal rules. Through creative use of available data, a large body of research has contributed to our understanding of public policy in state health insurance markets. This research plays an important role as recent trends suggest states are taking the lead in health care reform. However, several important questions have not been answered due to lack of data. This paper identifies some of these areas, and discusses how the Agency for Healthcare Research and Quality could push the research agenda in state health insurance policy further by augmenting the market-level data available to researchers. As states consider new forms of regulation and assistance for their insurance markets, there is increased need for better warehousing and maintenance of policy databases.

Cardiac Certificate of Need regulations and the availability and use of revascularization services

BACKGROUND

Many states enforce Certificate of Need (CON) regulations for cardiac procedures, but little is known about how CON affects utilization. We assessed the association between cardiac CON regulations, availability of revascularization facilities, and revascularization rates.

METHODS

We determined when state cardiac CON regulations were active and obtained data for Medicare beneficiaries > or = 65 years old who received coronary artery bypass graft surgery (CABG) or a percutaneous coronary intervention (PCI) between 1989 and 2002. We compared the number of hospitals performing revascularization and patient utilization in states with and without CON regulations, and in states which discontinued CON regulations during 1989 to 2002.

RESULTS

Each year, the per capita number of hospitals performing CABG and PCI was higher in states without CON (3.7 per 100,000 elderly for CABG, 4.5 for PCI in 2002), compared with CON states (2.5 for CABG, 3.0 for PCI in 2002). Multivariate regressions that adjusted for market and population characteristics found no difference in CABG utilization rates between states with and without CON (P = .7). However, CON was associated with 19.2% fewer PCIs per 1000 elderly (P = .01), equivalent to 322,526 fewer PCIs for 1989 to 2002. Among most states that discontinued CON, the number of hospitals performing PCI rose in the mid 1990s, but there were no consistent trends in the number of hospitals performing CABG or in PCIs or CABGs per capita.

CONCLUSIONS

Certificate of Need restricts the number of cardiac facilities, but its effect on utilization rates may vary by procedure.

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.

Effects of the State Children's Health Insurance Program on access to dental care and use of dental services

OBJECTIVE

To provide national estimates of implementation effects of the State Children's Health Insurance Program (SCHIP) on dental care access and use for low-income children.

DATA SOURCE

The 1997-2002 National Health Interview Survey.

STUDY DESIGN

The study design is based on variation in the timing of SCHIP implementation across states and among children observed before and after implementation. Two analyses were conducted. The first estimated the total effect of SCHIP implementation on unmet need for dental care due to cost in the past year and dental services use for low-income children (family income below state SCHIP eligibility thresholds) using county and time fixed effects models. The second analysis estimated differences in dental care access and use among low-income children with SCHIP or Medicaid coverage and their uninsured counterparts, using instrumental variables methods to control for selection bias. Both analyses controlled for child and family characteristics.

PRINCIPAL FINDINGS

When SCHIP had been implemented for more than 1 year, the probability of unmet dental care needs for low-income children was lowered by 4 percentage points. Compared with their uninsured counterparts, those who had SCHIP or Medicaid coverage were less likely to report unmet dental need by 8 percentage points (standard error: 2.3), and more likely to have visited a dentist within 6 or 12 months by 17 (standard error: 3.7) and 23 (standard error: 3.6) percentage points, respectively. SCHIP program type had no differential effects.

CONCLUSIONS

Consistent results from two analytical approaches provide evidence that SCHIP implementation significantly reduced financial barriers for dental care for low-income children in the U.S. Low-income children enrolled in SCHIP or Medicaid had substantially increased use of dental care than the uninsured.

Medicaid/State Children's Health Insurance Program patients and infectious diseases treated in emergency departments: U.S., 2003

OBJECTIVE

Emergency departments (EDs) are a critical source of medical care in the U.S. Information is sparse concerning infectious disease visits among Medicaid entitlement enrollees nationwide. The objective of this study was to describe infectious diseases in terms of Medicaid/State Children's Health Insurance Program (SCHIP) as an expected source of payment.

METHODS

Data for 2003 from the National Hospital Ambulatory Medical Care Survey (NHAMCS) were analyzed for infectious disease visits. NHAMCS is a national probability sample survey of visits to hospital EDs and outpatient departments of nonfederal, short-stay, and general hospitals in the U.S. Data are collected annually and are weighted to generate national estimates.

RESULTS

Nationally in 2003, an estimated 21.6 million visits were made to hospital EDs for infectious diseases (rate = 76 visits/1,000 people). Medicaid/SCHIP was the expected source of payment for an estimated 6.7 million infectious disease-related visits (rate = 200 visits/1,000 people covered by Medicaid). Children aged < 15 years made 39% of visits nationwide (nationwide rate = 139 visits/1,000 people). Of Medicaid visits, 63% were made by children < 15 years of age (Medicaid enrollees rate = 255 visits/1,000 people). The rate of visits for Medicaid enrollees was comparable for females and males (198 visits vs. 201/1,000 people). The rate of visits for black Medicaid enrollees was 33% higher than for white Medicaid enrollees (255 vs. 192 visits/1,000 people). Upper respiratory tract infection (URTI) is the most frequent infectious condition recorded at ED visits. An estimated 47% of ED visits with an expected pay source of Medicaid relate to URTIs (93 visits/1,000 people), compared with 38% of ED visits in general (29 visits/1,000 people).

CONCLUSION

Medicaid enrollee-specific ED visit rates for infectious diseases were higher by age group, gender, race, and region, compared with national rates. Because approximately half of visits relate to URTIs for a Medicaid payment group, URTIs should form the basis for development of appropriate control strategies.

Determinants of children's participation in California's Medicaid and SCHIP programs

OBJECTIVE

To develop a comprehensive predictive model of eligible children's enrollment in California's Medicaid (Medi-Cal [MC]) and State Children's Health Insurance Program (SCHIP; Healthy Families [HF]) programs.

DATA SOURCES/STUDY SETTING

2001 California Health Interview Survey data, data on outstationed eligibility workers (OEWs), and administrative data from state agencies and local health insurance expansion programs for fiscal year 2000-2001.

STUDY DESIGN

The study examined the effects of multiple family-level factors and contextual county-level factors on children's enrollment in Medicaid and SCHIP.

DATA COLLECTION/EXTRACTION METHODS

Simple logistical regression analyses were conducted with sampling weights. Hierarchical logistic regressions were run to control for clustering.

PRINCIPAL FINDINGS

Participation in MC and HF programs is determined by a combination of family-level predisposing, perceived need, and enabling/disabling factors, and county-level enabling/disabling factors. The strongest predictors of MC enrollment were family-level immigration status, ethnicity, and income, and the presence of a county-level "expansion program"; and the county-level ratio of OEWs to eligible children. Important HF enrollment predictors included family-level ethnicity, age, number of hours a parent worked, and urban residence; and county-level population size and outreach and media expenditure.

CONCLUSIONS

MC and HF outreach/enrollment efforts should target poorer and immigrant families (especially Latinos), older children, and children living in larger and urban counties. To reach uninsured eligible children, it is important to further simplify the application process and fund selected outreach efforts. Local health insurance expansion programs increase children's enrollment in MC.

Substitution Of SCHIP For Private Coverage: Results From A 2002 Evaluation In Ten States

This paper examines the extent to which the State Children's Health Insurance Program (SCHIP) might be substituting for private health insurance coverage at the time of enrollment. Among children who were newly enrolled in SCHIP in 2002 in ten states, about 14 percent had private coverage that they could have retained as an alternative to SCHIP. Of this 14 percent, about half of parents reported that the private coverage was unaffordable compared with SCHIP. This suggests that relatively few SCHIP enrollees could have retained private coverage and that even fewer had parents who felt that the option was affordable.

Economic burden of osteoporosis-related fractures in Medicaid

OBJECTIVE

There are limited studies concerning the economic burden of osteoporosis in the Medicaid population. This study estimated the direct cost of osteoporosis-related fractures (OPFx) to state Medicaid budgets.

METHODS

This retrospective analysis utilized Medicaid claims databases from three states, which included approximately 8 million Medicaid recipients. The study sample had at least one claim for an osteoporosis diagnosis (733.0x) between January 1, 2000 and December 31, 2001. Beneficiaries with a fracture and a diagnosis of osteoporosis were assigned to the case cohort. A propensity score-based matching method was used to select a cohort of controls with osteoporosis but without a fracture. An exponential conditional mean model was used to estimate the incremental annual cost associated with fractures.

RESULTS

The study cohort (n = 7626) and a 1:1 matched control group were identified. The study cohort was 85.8% female, had an average age of 65 years, were 53.2% white, and 48.9% were eligible for Medicare. There were significant increases (all P < 0.05) from the preperiod to study period for this cohort in the proportion that had at least one hospital admission (14.0% vs. 26.5%), nursing home admission (9.2% vs. 17.2%), home health (39.1% vs. 49.3%), or emergency room visit (21.3% vs. 31.9%). In contrast, the control cohort had very little increase in utilization. The regression-adjusted incremental cost for osteoporosis-related expenses in the year after fracture was estimated at $4007 per patient. The estimated incremental cost was $5370 for the subset of patients who were eligible for Medicare.

CONCLUSION

The economic burden of osteoporosis-related fractures on state Medicaid budgets is substantial.

The Effect of Medicaid Family Planning Expansions on Unplanned Births

BACKGROUND

Medicaid covers nearly 50% of all family planning services nationally. Between 1994 and 2001, 11 states implemented demonstration programs that expand coverage of family planning beyond the federally mandated minimum coverage levels.

METHODS

We estimate the effect of income- and postpartum-based eligibility expansions on birth rates using states that did not expand coverage as a control for states that did expand coverage. Our data span 1991-2001 and include all 50 states. We also estimate net expansion costs from societal and state perspectives for 5 expansions that published incremental expansion costs.

RESULTS

We find that Medicaid eligibility expansions lowered average annual birth rates in all states. Birth rates were reduced on average by 1.95 points in income-based expansions and by 0.87 points in postpartum-based expansions. The cost offset of maternal and child health expenditures of the expansions exceed program costs in all states but California. This result is likely because the objectives and scope of the California program goes beyond just unplanned births, which makes the program cost higher relative to the reduction in births.

CONCLUSIONS

Both income- and postpartum-based family planning expansions either yield financial benefits or, at the very least, are cost neutral from the perspective of state governments. Income-based expansions are significantly more effective because eligibility is not limited to only postpartum women. The experience of these early family planning expansions should be a guide for other states considering family planning benefit expansions. From the national perspective, 4 out of 5 programs were cost neutral, although California had significantly higher costs. From the state's perspective, all of the expansions were either budget neutral or yielded a net cost savings.

State Variation In Medicaid Spending: Hard To Justify

There is great variation among states in Medicaid spending per low-income person. This variation has many determinants, including state discretion and differences in prices and amounts of services used. Incentives in Medicaid to have low-income states spend more have generally not worked. The decentralized approach to Medicaid and the variations in spending created thereby have consequences in access and health outcomes that seem to belie a presumed national interest in equity. The current trend toward state-based solutions to health care coverage would likely exacerbate existing variations. A federal solution, though not likely, would be necessary to eliminate state variations.

Coping With SCHIP Enrollment Caps: Lessons From Seven States’ Experiences

Seven states with separate (as opposed to Medicaid expansion) State Children's Health Insurance Programs (SCHIP) implemented enrollment caps during the 2001-2003 recession. Interviews with SCHIP officials and Covering Kids and Families grantees in these states examined implementation policies and their effects on enrollment, outreach, and public support. Enrollment caps were generally maintained for less than a year and resulted in large spending reductions, but enrollment declined steeply. Most key informants indicated that caps were preferable to reversals of simplified enrollment, comprehensive benefits, and low cost sharing and thus offered policymakers an important tool for controlling costs.

Medicaid and SCHIP coverage: findings from California and North Carolina

This article examines experiences under Medicaid and the State Children's Health Insurance Program (SCHIP), drawing on surveys of over 3,000 enrollees in California and North Carolina in 2002. In both States, Medicaid enrollees were less likely than SCHIP enrollees to have parents who were covered by employer-sponsored insurance (ESI). With the exception of dental care and provider perceptions, access experiences were fairly comparable across the two programs, despite differences in the characteristics of the children served by the two programs. Relative to being uninsured, Medicaid enrollment was found to improve access to care along a number of different dimensions, controlling for other factors. Furthermore, this study emphasizes the need for continued evaluation of access to care for both programs.

Health Spending By State Of Residence, 1991–2004

Differing trends in health spending by state underlie national spending trends. To shed light on the complexities of health spending patterns among state residents, we present updated per capita health spending estimates by state of residence for 1991-1998 and new estimates for 1999-2004, and we offer summaries of trends exhibited during these time periods. These statistics provide the opportunity for further analysis, such as examination of variations in state-level spending in Medicare, Medicaid, and total personal health care spending, which can yield new perspectives on recent state health spending trends and provide context for policy discussions.
