Outcomes Associated With State Policies Enabling Provision of Oral Health Services in Medical Offices Among Medicaid-enrolled Children.

BACKGROUND: To increase receipt of preventive oral health services (POHS), all state Medicaid programs have enacted policies to encourage nondental providers to deliver POHS in medical offices. This study examined if these Medicaid policies improved oral health, as measured by reductions in dental visits with treatment and preventable emergency department (ED) visits for nontraumatic dental conditions (NTDC). METHODS: Using data on children aged 6 months to up to 6 years from 38 state Medicaid programs during 2006-2014, we used a generalized difference-in-differences estimation approach to examine the probability of a child having, in a year, any dental visits with caries-related treatment and any ED visits for NTDC, conditional on length of policy enactment. Models included additional child-level and county-level characteristics, state and year fixed effects, probability weights, and clustered standard errors. RESULTS: Among a weighted sample of 45,107,240 child/year observations, 11.7% had any dental visits with treatment and 0.2% had any ED visits for NTDC annually. Children in states with and without medical POHS policies had similar odds of having any dental visits with treatment, regardless of length of policy enactment. Children in states with medical POHS policies enacted for one or more years had significantly greater odds of having any ED visits for NTDC (P<0.05). CONCLUSIONS: State policies making POHS available in medical offices did not affect rates of dental visits with caries-related treatment, but were associated with increased rates of potentially avoidable ED visits for NTDC. Findings suggest that many young Medicaid-enrollees lack access to dentists.

Impact of Medicaid Policy on the Oral Health of Publicly Insured Children.

Objective Fluoride varnish (FV) applications among non-dentist primary care providers has increased due to state Medicaid policies. In this study we examine the impact of FV policies on the oral health of publicly insured children aged 2-6 years old. Methods Using three waves of the National Survey of Children's Health (2003, 2007, 2011/12), we used a logistic regression model with state and year fixed effects, adjusting for relevant child characteristics, to examine the association between years since a state implemented a FV policy and the odds of a publicly insured child having very good or excellent teeth. We compared children with public insurance in states with FV policies to children with public insurance in states without FV policies, controlling for the same difference among children with private insurance who were unlikely to be affected by Medicaid FV policies. Results Among 68,890 children aged 2-6 years, 38% had public insurance. Compared to privately insured children, publicly insured children had significantly lower odds of having very good or excellent teeth [odds ratio (OR) 0.70, 95% CI 0.62-0.81]. Publicly insured children in states with FV policies implemented for four or more years had significantly greater odds of having very good or excellent teeth (OR 1.28, 95% CI 1.03-1.60) compared to publicly insured children in states without FV policies. Conclusions for Practice State policies supporting non-dental primary care providers application of FV were associated with improvements in oral health for young children with public insurance.

Clinician characteristics associated with fluoride varnish applications during well-child visits.

OBJECTIVES: To identify factors associated with clinicians' likelihood and intensity of applying fluoride varnish (FV) overall and for visits paid by Medicaid and private insurers. STUDY DESIGN: Observational study using claims data. METHODS: Using the Massachusetts All-Payer Claims Database (2016-2018), we conducted a repeated cross-sectional study of 2911 clinicians (7277 clinician-year observations) providing well-child visits to children aged 1 to 5 years. Zero-inflated negative binomial models estimated the probability of a clinician applying FV and the number of visits with FV applications, overall and separately for visits paid by Medicaid and private insurers. RESULTS: A total of 30.9% of clinician-years applied FV at least once, and overall, an average of 8.4% of a clinician's well-child visits included FV annually. Controlling for all covariates, having a higher percentage of patients insured by Medicaid was associated with applying FV (OR, 1.35; 95% CI, 1.23-1.45) and a higher expected number of applications (OR, 1.05; 95% CI, 1.02-1.09). Additionally, having a higher percentage of patients aged 1 to 5 years was associated with applying FV (OR, 1.20; 95% CI, 1.01-1.43), but not the number of applications. Similar associations were observed among visits paid by private insurers. CONCLUSIONS: Despite clinical recommendations and mandated insurance reimbursements, the likelihood and intensity of FV applications was low for most pediatric primary care clinicians. Clinician behavior was associated with patient-panel characteristics, suggesting the need for interventions that account for these differences.

The Patient Protection and Affordable Care Act and Pediatric Medical Clinicians' Application of Fluoride Varnish.

Importance: Fluoride varnish reduces children's tooth decay, yet few clinicians provide it. Most state Medicaid programs have covered this service during medical visits for children aged 1 to 5 years, but private insurers began covering it only in 2015 due to the Patient Protection and Affordable Care Act (ACA) mandate that they cover a set of recommended preventive services without cost-sharing. Evidence on clinicians' behavior change postmandate is limited. Objective: To examine monthly changes in fluoride varnish applications among pediatric clinicians following the ACA mandate. Design, Setting, and Participants: Using all-payer claims data from Massachusetts, this cohort study applied an interrupted time-series approach with linear regression models comparing changes in monthly clinician-level outcomes before and after the mandate. Participants included clinicians who billed at least 5 well-child visits for patients aged 1 to 5 years and were observed at least once premandate. Adjusted for clinician fixed effects, models were assessed overall and separately for clinicians categorized by their monthly share of well-child visits paid by private insurers before the mandate: mostly private (>66% of visits paid by private insurers), mostly public (<33% of visits paid by private insurers), or mixed (33%-66% of visits paid by private insurers) insurance types. Analysis was performed from June 1, 2022, to July 31, 2023. Exposure: Preenactment and postenactment of the ACA mandate for private insurers to cover fluoride varnish applications without cost-sharing. Main Outcomes and Measures: Clinician-month measures of whether fluoride varnish was provided during at least 1 well-child visit and the share of such visits, analyzed separately for clinicians who did and did not apply fluoride varnish premandate. Results: The sample included 2405 clinicians, with 107 841 clinician-months. Premandate, 10.48% of the visits included fluoride varnish applications. Two years postmandate, the likelihood of ever applying fluoride varnish was 13.64 (95% CI, 10.97-16.32) percentage points higher. For clinicians providing fluoride varnish premandate, the share of visits with fluoride varnish increased by 9.22 (95% CI, 5.41-13.02) percentage points. This increase was observed in clinicians who treated children with insurance that was mostly mixed and mostly private; no substantial change was observed among those treating children with mostly public insurance. Conclusions and Relevance: In this cohort study of pediatric primary care clinicians, an association between the ACA mandate and an increase in fluoride varnish application was observed, especially among clinicians primarily treating privately insured patients and those applying it premandate. However, application remains infrequent, suggesting persistent barriers.

Association Between Insurance Type and Fluoride Varnish Application During Well-Child Visits in Massachusetts.

OBJECTIVE: To compare rates of fluoride varnish (FV) applications during well-child visits for children covered by Medicaid and private medical insurance in Massachusetts. METHODS: This cross-sectional study analyzed well-child visits for children aged 1 to 5 years paid by Medicaid and private insurance during 2016.Çô18 in Massachusetts. Multivariate regression models, with all covariates interacting with insurance type, were used to calculate odds ratios and adjusted predicted probabilities of fluoride varnish during well-child visits by calendar year and age. RESULTS: Across 957,551 well-child visits, 40.0% were paid by private insurers. Unadjusted rates of fluoride varnish were significantly lower among well-child visits paid by private insurers (6.6%) than visits paid by Medicaid (14.2%). In the fully interacted regression model, the odds of a visit including fluoride varnish were significantly lower for older children than for children aged 1 for visits paid by both insurance types. Adjusted rates of fluoride varnish increased significantly from 2016 to 2018 for both insurance types. Moreover, rates were higher among visits for children covered under Medicaid than privately insured children in all years, and the differences by insurance type declined over time (2016: 8.0% points, 95% confidence interval.á=.á.êÆ8.7 to .êÆ7.3, 2018: 5.3% points, 95% confidence interval.á=.á.êÆ6.6 to .êÆ3.9). CONCLUSIONS: Rates of fluoride varnish applications during well-child visits were low for both Medicaid and private insurance despite growth from 2016 to 2018 in Massachusetts. Low rates are concerning because this is a recommended service with the potential to help address racial, geographic, and income-based disparities in access and oral health outcomes.

Barriers and Facilitators to Optimal Fluoride Varnish Application.

OBJECTIVE: National guidelines recommend that all children under age six receive fluoride varnish (FV) in medical settings. However, application rates remain low. This study aimed to update understanding of barriers and facilitators to guideline concordant FV application. METHODS: We conducted virtual semi-structured interviews with a purposive sample (eg, FV application rates, geographic location, practice size and type) of pediatric primary care clinicians and medical assistants in Massachusetts between February 1 and June 30, 2022. The Consolidated Framework for Implementation Research (CFIR) served as the study's theoretical framework and data were analyzed using a modified grounded theory approach. RESULTS: Of the 31 participants, 90% identified as White and 81% as female. Major themes, which linked to four CFIR domains, included: variation in perceived adequacy of reimbursement; differences in FV application across practice types; variation in processes, protocols, and priorities; external accountability for quality of care; and potential levers for change. Important subthemes included challenges for small practices; role of quality measures in delivering guideline-concordant preventive oral health care; and desire for preventive care coordination with dentists. CONCLUSIONS: This study suggests that potential barriers and facilitators to guideline concordant FV application exist at multiple levels that may warrant further study. Examples include testing the effectiveness of quality measures for FV application and testing strategies for implementing consistent processes and protocols for improving FV application rates.

Variation in prices for an evidence-based pediatric preventive service.

OBJECTIVE: To examine variation in prices paid by private medical insurers for fluoride varnish applications in medical settings, a newly reimbursed service that few children receive. DATA SOURCES: Private-insurance medical claims from Connecticut, Maine, New Hampshire, and Rhode Island (2016-2018). STUDY DESIGN: We examined prices paid for fluoride varnish by private insurers and compared these to prices paid by Medicaid. DATA COLLECTION/EXTRACTION METHODS: Private claims for fluoride varnish during medical visits for children aged 1-5 years. State Medicaid rates for fluoride varnish were obtained from the American Academy of Pediatrics. PRINCIPAL FINDINGS: Prices paid for fluoride varnish by private insurers varied within and across states, ranging from less than $5 to $50. Median prices closely followed Medicaid rates in three of the four states. In states covering a package of fluoride varnish plus additional preventive oral health services during medical visits, combined Medicaid rates were nearly double the median price paid by private insurers. CONCLUSIONS: Fluoride varnish is a recommended service, but few children receive it. Price variation may contribute to the low uptake of this service. Ensuring sufficient Medicaid and private insurance rates could increase fluoride varnish applications in medical settings and improve oral health.

Delivery of fluoride varnish during pediatric medical visits by rurality.

OBJECTIVES: To examine variation in the delivery of fluoride varnish during pediatric medical visits by rurality. METHODS: This observational study used private health insurance claims (2016-2018) for children aged 1-5 years from Connecticut, Maine, New Hampshire, and Rhode Island linked to the county-level Rural-Urban Continuum codes. County-level Rural-Urban Continuum codes were categorized into three groups: metropolitan, rural, and remote rural. Logistic regression models were used to estimate the odds of a well-child medical visit including fluoride varnish by county rurality, adjusting for other individual and county characteristics. RESULTS: Among 328,661 pediatric well-child visits paid by private insurance, fluoride varnish was included in 4.3% of visits in metropolitan counties, 6.2% of visits in rural counties, and 10.3% of visits in remote rural counties. There were significantly higher odds of a visit including fluoride varnish in rural remote counties (odds ratio [OR] = 3.5, 95% confidence interval [CI] = 2.3-5.3, p < 0.001) and in rural counties (OR = 2.4, 95% CI = 1.4-4.0, p < 0.001) compared to metropolitan counties. Rates of fluoride varnish during well-child visits increased since 2016 in metropolitan counties and remained stable in rural counties. CONCLUSIONS: All young children are recommended to receive fluoride varnish applications in medical settings, yet overall rates were low. For privately insured young children, pediatric well-child medical visits were more likely to include fluoride varnish in rural and rural remote counties than metropolitan counties.

Variation in Current Guidelines for Fluoride Varnish Application for Young Children in Medical Settings in the United States.

Background: The United States Preventive Services Task Force recommends that medical providers apply fluoride varnish (FV) to the teeth of all children under 6 years of age, but fewer than 10% of eligible children receive FV as recommended. Prior studies suggest that variation in clinical guidelines is associated with low uptake of other evidence-based health-related interventions, but consistency of national guidelines for the delivery of FV in medical settings is unknown. Methods: Eligible guidelines for application of FV in medical settings for children under 6 years of age were published in the past 10 years by national pediatric or dental professional organizations or by national public health entities. Guidelines were identified using the search terms fluoride varnish + [application; guidelines, or recommendations; children or pediatric; American Academy of Pediatrics (AAP); American Academy of Pediatric Dentistry] and a search of Guideline Central. Details of the guidelines were extracted and compared. Results: Ten guidelines met inclusion criteria. Guidelines differed in terms of periodicity recommendations and whether FV was indicated for children with a dental home or level of risk of dental caries. Conclusion: Numerous recommendations about FV delivery in medical settings are available to pediatric medical providers. Further study is warranted to determine whether the variation across current guidelines detected in this study may contribute to low FV application rates in medical settings.

Impact of state-level training requirements for medical providers on receipt of preventive oral health services for young children enrolled in Medicaid.

OBJECTIVES: Young children enrolled in Medicaid make few dental visits and have high rates of tooth decay. To improve access to care, state Medicaid programs have enacted policies encouraging nondental providers to deliver preventive oral health services (POHS) in medical offices. Policies vary by state, with some states requiring medical providers to obtain training prior to delivering POHS. Our objective was to test whether these training requirements were associated with higher rates of POHS for Medicaid-enrolled children <6 years. METHODS: This study took advantage of a natural experiment in which policy enactment occurred across states at different times. We used Medicaid Analytic eXtract enrollment and claims data, public policy data, and Area Health Resource Files data. We examined an unweighted sample of 8,711,192 (45,107,240 weighted) Medicaid-enrolled children <6 years in 38 states from 2006 to 2014. Multivariable logistic regression models estimated the odds a child received POHS in a calendar year. Results are presented as adjusted probabilities. RESULTS: Five or more years after policy enactment, the probability of a child receiving POHS in medical offices was 10.7 percent in states with training requirements compared to 5.0 percent in states without training requirements (P = 0.01). Findings were similar when receipt of any POHS in medical or dental offices was examined 5 or more years post-policy-enactment (requirement = 42.5 percent, no requirement = 33.6 percent, P < 0.001). CONCLUSIONS: Medicaid policies increased young children's receipt of POHS and at higher rates in states that required POHS training. These results suggest that oral health training for nondental practitioners is a key component of policy success.

Medicaid Payment and Fluoride Varnish Application During Pediatric Medical Visits.

All Medicaid programs pay for fluoride varnish applications during medical visits for infants and toddlers, but receipt of care varies considerably across states. Using 2006-2014 Medicaid data from 22 states, this study examined the association between Medicaid payment and receipt of fluoride varnish during pediatric medical visits. Among 3,393,638 medical visits, fewer than one in 10 visits included fluoride varnish. Higher Medicaid payment was positively associated with receipt of fluoride varnish during pediatric medical visits. As policymakers consider strategies for increasing young children's access to preventive oral health services, as well as consider strategies for balancing budgets, attention should be paid to the effects of provider payment on access to pediatric oral health services.

Racial/Ethnic Differences in Receipt of Oral Health Services in Medical and Dental Offices: Impact of Medicaid Policies on Young Children.

Purpose: The purpose of this study was to examine receipt of preventive oral health services (POHS) by race/ethnicity for young Medicaid-enrollees following the enactment of state policies enabling medical providers to deliver POHS. Methods: Using Medicaid data (2006 to 2014) from 38 states for 8,711,192 child-years (aged six months to five years), logistic regressions were used to examine differences within and between racial/ethnic groups (white, black, Hispanic, and "other" race/ethnicity groups) in terms of adjusted probabilities of receiving POHS in medical offices or any medical or dental offices. Models were adjusted for years since policy enactment and estimated separately for states with and without requirements that medical providers obtain POHS training. Results: Receipt of any POHS was 10.9 percentage points higher for Hispanic children and 4.7 percentage points higher for "other" race/ethnicity group children than white children after five or more years of policy enactment in states with training requirements (P<0.05). Findings for medical POHS and states without training requirements were similar but smaller in magnitude. Conclusions: Hispanic and "other" race/ethnicity group children benefitted more from the integration of POHS into medical offices than white children. Policies enabling delivery of POHS in medical offices increased receipt of POHS among some minority groups and may help to reduce disparities.

Impact of a Medicaid policy on preventive oral health services for children with intellectual disabilities, developmental disabilities, or both.

BACKGROUND: Integrating preventive oral health services (POHS) into medical offices may ease access to care for children with intellectual and developmental disabilities (IDD). The authors examined the impact of state policies allowing delivery of POHS in medical offices on receipt of POHS among Medicaid enrollees with IDD. METHODS: The authors used 2006 through 2014 Medicaid data for children with IDD aged 6 months through 5 years from 38 states. IDD were defined using 14 condition codes from Centers for Medicare & Medicaid Services Chronic Conditions Data Warehouse. The length of the state's medical POHS policy (no policy, < 1 year, 1 year, 2 years, 3 years, or ≥ 4 years) was interacted with an indicator that the child was younger than 3 years. The authors used logistic regression models to estimate the likelihood that a child received POHS in a medical office or in a medical or dental office in a given year. RESULTS: Among 447,918 children with IDD, 1.6% received POHS in medical offices. Children younger than 3 years in states with longer-enacted policies had higher rates of receiving POHS. For example, the predicted probability of receiving POHS was 40.6% (95% confidence interval, 36.3% to 44.9%) for children younger than 3 years in states with a medical POHS policy for more than 4 years compared with 30.6% (95% confidence interval, 27.8% to 33.5%) for children in states without a policy. CONCLUSIONS: State Medicaid policies allowing delivery of POHS in medical offices increased receipt of POHS among Medicaid-enrolled children with IDD who were younger than 3 years. PRACTICAL IMPLICATIONS: Few children with IDD receive POHS in any setting. Efforts are needed to reduce barriers to POHS for publicly insured children with IDD.

Low rates of pediatric dental coverage for families purchasing marketplace insurance plans.

OBJECTIVES: Pediatric dental care is an essential health benefit that the Affordable Care Act (ACA) requires most private health plans to cover. Insurance marketplaces have flexibility in how pediatric dental coverage is offered, with states requiring purchase of dental coverage or embedding dental coverage in all medical plans. It is unknown how these different offerings may affect uptake of coverage. METHODS: We analyzed the 2014-2015 National Health Interview Survey to determine rates of private dental coverage for children obtaining private medical insurance from all state marketplaces (weighted N = 12,380). RESULTS: We found low rates of dental coverage for children in states where purchase of dental coverage was required (9%) and in states where all marketplace medical plans had embedded dental coverage (24%). CONCLUSIONS: Few families obtaining private medical insurance on the marketplaces report having pediatric dental coverage, suggesting that the ACA essential health benefit policy may not be having its intended effect.

Changes in pediatric dental coverage and visits following the implementation of the affordable care act.

OBJECTIVE: To determine the impact of the inclusion of pediatric dental care in the Affordable Care Act's (ACA) core package of essential health benefits on dental coverage and utilization. DATA SOURCES: Children aged 1-18 years included in the nationally representative 2010-2015 National Health Interview Survey (NHIS). STUDY DESIGN: We used regression-adjusted difference-in-differences to examine changes in rates of dental coverage and visits pre- and post-ACA for children likely to be affected by the ACA (have a parent working for a small employer) to a comparison group of children who were unlikely to be affected (have a parent in a firm with ≥50 employees). Models adjusted for relevant health and sociodemographic measures. DATA COLLECTION: NHIS is an annual household survey conducted by the National Center for Health Statistics. PRINCIPAL FINDINGS: Comparing pre- and post-ACA periods, private dental insurance increased by 4.6 percentage points more (P = 0.013) and annual dental visits were unchanged (2.7 percentage points, P = 0.071) among children likely to be affected by the ACA compared to children unlikely to be affected by the ACA. CONCLUSION: Inclusion of pediatric dental care as an ACA essential health benefit increased dental insurance coverage, but not dental visits among children likely to be affected by this policy.

Delivery of Preventive Oral Health Services by Rurality: A Cross-Sectional Analysis.

PURPOSE: Integrating oral health care into primary care has been promoted as a strategy to increase delivery of preventive oral health services (POHS) to young children, particularly in rural areas where few dentists practice. Using a multistate sample of Medicaid claims, we examined a child's odds of receiving POHS in a medical office by county rurality. METHODS: We used 2012-2014 Medicaid Analytic extract claims data for 6,275,456 children younger than 6 years in 39 states that allowed Medicaid payment for POHS in medical offices. We used county-level characteristics from the Area Health Resources Files, including a 3-level measure of county rurality. We used logistic regression to estimate a child's odds of receiving POHS in a medical office by county rurality, while controlling for other patient and county characteristics. FINDINGS: POHS in medical offices were received by 7.8% of children. Rates of POHS in medical offices were higher in metropolitan (metro) counties (8.4%) than nonmetro adjacent to metro (5.8%) and nonmetro not adjacent to metro (4.3%). In adjusted analysis, children living in nonmetro not adjacent to metro (OR = 0.79, 95% CI: 0.64-0.99) and adjacent to metro counties (OR = 0.70, 95% CI: 0.59-0.82) were significantly less likely to receive POHS in medical offices than children living in metro counties. CONCLUSIONS: In this study of POHS in medical offices among young Medicaid-enrolled children, we found POHS rates were lowest in nonmetro counties. Given barriers to dental care in rural areas, states should take additional steps beyond allowing Medicaid reimbursement to increase delivery of POHS in medical offices.

Association between type of health insurance and children's oral health, NHANES 2011-2014.

OBJECTIVES: To examine the association between type of health insurance (public, uninsured, private, or other) and oral health outcomes for children in the United States using nationally representative surveillance data. METHODS: Using the National Health and Nutrition Examination Survey (2011/12-2013/14), logistic regression models were used to estimate the odds of any dental caries and any untreated caries by type of health insurance (public, uninsured, private, and other) for children aged 2-19 years, with adjustment for relevant individual and socioeconomic characteristics. RESULTS: Among 6,057 children, the odds of having any dental caries or untreated caries was not significantly different for publicly insured and uninsured children compared to privately insured children, when adjusting for family income and education. Children in families with income to poverty ratios <200 percent had greater odds of caries and untreated caries relative to children in families with income to poverty ratios ≥400 percent. Children with less educated parents also experienced greater odds of caries and untreated caries. CONCLUSIONS: Oral health outcomes, after adjusting for covariates, were similar for children with public and private health insurance. However, children in low-income families and with less educated parents had greater odds of untreated caries and dental caries, suggesting that initiatives focused on publicly insured populations may miss other vulnerable children of low socioeconomic status.

Improved access and quality of care after enrollment in the New York State Children's Health Insurance Program (SCHIP).

BACKGROUND: Although many studies have noted that uninsured children have poorer access and quality of health care than do insured children, few studies have been able to demonstrate the direct benefits of providing health insurance to previously uninsured children. The State Children's Health Insurance Program (SCHIP), enacted as Title XXI of the Social Security Act, was intended to improve insurance coverage and access to health care for low-income, uninsured children. With limited state and federal resources for health care, continued funding of SCHIP requires demonstration of success of the program. As yet, little is known about the effectiveness of SCHIP on improving access and quality of care to enrollees. OBJECTIVES: To measure the impact of the New York State (NYS) SCHIP on access, utilization, and quality of health services for enrolled children. DESIGN SETTING: NYS, stratified into 4 regions. The NYS SCHIP is modeled on commercial insurance (32 managed care plans) and at the time of the study had 18% of SCHIP enrollees nationwide. STUDY DESIGN: For the study group, the design used pre/poststudy telephone interviews of parents of children enrolling in the NYS SCHIP, with baseline interviews soon after enrollment and follow-up interviews 1 year after enrollment. Baseline interviews reflected the child's experience during the 1-year period before enrollment in SCHIP. The follow-up interviews reflected the 1-year period after enrollment in SCHIP. For the comparison group, the design used baseline interviews of a comparison group enrolled 1 year after the study group to test for secular trends; these interviews reflected the 1-year period before enrollment in SCHIP. SUBJECTS: Children (n = 2644) 0 to 18 years of age who enrolled in the NYS SCHIP for the first time (November 2000 to March 2001), stratified by age (0-5, 6-11, and 12-18 years), race/ethnicity (white non-Hispanic, black non-Hispanic, and Hispanic; others excluded), and region of NYS. The comparison group consisted of 400 children. Telephone interviews were conducted in English or Spanish throughout the day and evening, 7 days per week, to obtain measures. MAIN OUTCOME MEASURES: Demographic and health measures (child and family characteristics, health status, presence of a special health care need, and prior health insurance), access (usual source of care [USC] and unmet needs for health care), utilization (visits for specific health services), and quality (continuity with USC and measures of primary care interactions). Analyses included bivariate tests, comparing the pre-SCHIP period to the 1-year period after enrollment in SCHIP. Multivariate models were computed to generate standardized populations comprised of key characteristics of the sample to test for differences in measures (after SCHIP versus before SCHIP), controlling for demographic characteristics. RESULTS: Of the 2644 study-group children who completed the initial interview, 2290 (87%) completed the follow-up interview. Key measures for the pre-SCHIP period and short-term "postenrollment" measures for the study group were not statistically different from measures for the comparison group, suggesting no major secular trends. Participants were non-Hispanic white (25%), non-Hispanic black (31%), and Hispanic (45%). Fifty-one percent of the parents were single, and 61% had a high school education or less; 81% of families had income <160% of the federal poverty level. Sixty-two percent of the children were uninsured > or = 12 months before the NYS SCHIP; of those insured, 43% previously had Medicaid. The proportion of children who had a USC increased after enrollment in the NYS SCHIP (86% to 97%). Two measures of accessibility (difficulty getting a medical person by telephone and difficulty getting an appointment) improved after enrollment in SCHIP. The proportion of children with any unmet health care needs decreased (31% to 19%). Specific types of unmet need also were reduced after enrollment; for example, among SCHIP enrollees who had a need for specific type of care, unmet needs wds were significantly lower postenrollment versus pre-SCHIP for specialty care (-15.5% in unmet need), acute care (-10.1%), preventive care (-9.6%), dental care (-13.0%%), and vision care (-13.2%). Emergency and total ambulatory visits did not change, but the proportion of children with a preventive care visit increased (74% to 82%). The proportion of children who used their USC for most or all visits increased (47% to 89%), demonstrating increased continuity of care. Several indicators of health care quality improved, including an overall rating of quality, the 4 indicators of physician-patient interaction used by the Consumer Assessment of Health Plans Survey, and a measure of parental worry about their child's health. Improvements were noted among major subgroups of children, with the greatest improvements for those with the lowest baseline levels. For example, at baseline, a lower percentage of children living at <160% of the federal poverty level had a presence of a USC or continuity with their USC than children living in families at >160% of the federal poverty level, and these poorer children experienced the greatest gains in having a USC or having continuity with their USC after enrollment in SCHIP. CONCLUSIONS: Enrollment in the NYS SCHIP was associated with 1) improved access, continuity, and quality of care and 2) a change in the pattern of health care, with a greater proportion of care taking place within the usual source of primary care.

The evolution of the State Children's Health Insurance Program (SCHIP) in New York: changing program features and enrollee characteristics.

BACKGROUND: The State Children's Health Insurance Program (SCHIP) has been operating for >5 years. Policy makers are interested in the characteristics of children who have enrolled and changes in the health care needs of enrolled children as programs mature. New York State's SCHIP evolved from a similar statewide health insurance program that was developed in 1991 (Child Health Plus [CHPlus]). Understanding how current SCHIP enrollees differ from early CHPlus enrollees together with how program features changed during the period may shed light on how best to serve the evolving SCHIP population. OBJECTIVE: To 1) describe changes in the characteristics of children enrolled in 1994 CHPlus and 2001 SCHIP; 2) determine if changes in the near-poor, age-eligible population during the time period could account for the evolution of enrollment; and 3) describe changes in the program during the period that could be responsible for the enrollment changes. SETTING: New York State, stratified into 4 regions: New York City, New York City environs, upstate urban counties, and upstate rural counties. DESIGN: Retrospective telephone interviews of parents of 2 cohorts of CHPlus enrollees: 1) children who enrolled in CHPlus in 1993 to 1994 and 2) children who enrolled in New York's SCHIP in 2000 to 2001. The Current Population Survey (CPS) 1992 to 1994 and 1999 to 2001 were used to identify secular trends that could explain differences in the CHPlus and SCHIP enrollees. PROGRAM CHARACTERISTICS: 1994 CHPlus and 2001 SCHIP were similar in design, both limiting eligibility by age, family income, and insurance status. SCHIP 2001 included 1) expansion of eligibility to adolescents 13 to 19 years old; 2) expansion of benefits to include hospitalizations, mental health, and dental benefits; 3) changes in premium contributions; 4) more participating insurance plans, limited to managed care; 5) expansions in marketing and outreach; and 6) a combined enrollment application for SCHIP and several low-income programs including Medicaid. SAMPLE: Cohort 1 included 2126 new CHPlus enrollees 0 to 13 years old who were enrolled for at least 9 months, stratified by geographic region. Cohort 2 included 1100 new SCHIP enrollees 0 to 13 years old who were enrolled for at least 9 months, stratified by geographic region, age, race, and ethnicity. Results were weighted to be representative of statewide CHPlus or SCHIP new enrollees who met the sampling criteria. Samples of age- and income-eligible children from New York State were drawn from the CPS and pooled and reweighted (1992-1994 and 1999-2001) to generate a comparison group of children targeted by CHPlus and SCHIP. MEASURES: Sociodemographic characteristics, race and ethnicity (white non-Hispanic, black non-Hispanic, and Hispanic), prior health insurance, health care access, and first source of information about the program. ANALYSES: Weighted bivariate analyses (comparisons of means and rates) adjusted for the complex sampling design to compare measures between the 2 program cohorts and between the 2 CPS samples. We tested for equivalence by using chi2 statistics. RESULTS: As the program evolved from CHPlus to SCHIP, relatively more black and Hispanic children enrolled (9% to 30% black from 1994 to 2001, and 16% to 48% Hispanic), more New York City residents (46% to 69% from 1994 to 2001), more children with parents who had less than a high school education (10% to 25%), more children from lower income families (59% to 75% below 150% of the federal poverty level), and more children from families with parents not working (7% to 20%) enrolled. These socioeconomic and demographic changes were not reflected in the underlying age- and income-eligible population. A greater proportion of 2001 enrollees were uninsured for some time immediately before enrollment (57% to 76% had an uninsured gap), were insured by Medicaid during the year before enrollment (23% to 48%), and lacked a USC (5% to 14%). Although "word of mouth" was the most common means by which families heard about both programs, a greater proportion of 2001 enrollees learned about SCHIP from marketing or outreach sources. CONCLUSION: As New York programs for the uninsured evolved, more children from minority groups, with lower family incomes and education, and having less baseline access to health care were enrolled. Although changes in the underlying population were relatively small, progressively increased marketing and outreach, particularly in New York City, the introduction of a single application form for SCHIP and Medicaid, and expansions in the benefit package may have accounted, in part, for the large change in the characteristics of enrollees.
