Objective: This study examined adherence to clinical practice guidelines (CPGs) and U.S. Food and Drug Administration (FDA) medication labels when prescribing psychotropic medications to Medicaid-insured children with attention-deficit hyperactivity disorder (ADHD)., Methods: A retrospective analysis was conducted with 2016-2018 Medicaid claims data across 46 states for children with an ADHD diagnosis and at least one psychotropic medication prescription (N=1,236,068 children). Medications recommended for pediatric use were identified with CPGs from the American Academy of Child and Adolescent Psychiatry and the Florida Medicaid Drug Therapy Management Program for Behavioral Health., Results: Across 46 states, 86.7% of children received guideline-recommended and FDA-approved medications for the treatment of ADHD and comorbid mental disorders. Antidepressants, antihistamines, and second-generation antipsychotics that were not included in CPGs were prescribed for 23.4% of children., Conclusions: High adherence to CPGs and FDA medication labels for medications prescribed for ADHD was observed, suggesting the effectiveness of guidelines in driving evidence-based care., Competing Interests: Dr. Naylor is the psychiatric consultant to the Illinois Department of Children and Family Services (DCFS) Psychotropic Medication Consent Program and is paid via a contract between the University of Illinois Chicago and DCFS.

Objective: This study evaluates the dentists' availability to deliver preventive dental care to children in schools and the impact of school-based programs on access., Methods: The study population included Florida elementary-school children, differentiated by dental insurance (Medicaid, CHIP, private, or none). We considered the implementation of school-based programs using optimization modeling to (re)allocate the dentists' caseload to schools to meet demand for preventive care under resource constraints. We considered multiple settings for school-based program implementation: (i) school prioritization; and (ii) dentists' participation in public insurance. Statistical inference was used to identify communities to improve access and reduce disparities., Results: School-based programs reduced unmet demand (3%-12%), being more efficient if prioritizing schools in communities targeted to improve access. The access improvement varied by insurance status and geography. Uninsured urban children benefited most from school-based programs, with 15%-75% unmet need reduction. The percentage of urban communities targeted to improve access decreased by 12% against no-school program. Such percentage remained large for suburban (15%-100%) and rural (50%-100%) communities. Disparity in access for public-insured vs. private-insured children persisted under school-based programs (32%-84% identified communities)., Conclusion: School-based programs improve dental care access; the improvement was however different by insurance status, with uninsured children benefiting the most. Accounting to the dentists' availability in prioritizing schools resulted in effective resource allocation to school-based programs. Access disparities between public and private-insured children did not improve; school-based programs shifted resources from public-insured to uninsured. School-based programs are effective in addressing access barriers to those children experiencing them most., (© 2022 American Association of Public Health Dentistry.)

Objective: Prior studies have identified low rates of engagement in mental health (MH) services in clinic settings among children enrolled in Medicaid. Yet, little is known about whether the delivery of in-home MH treatment (in which the clinician travels to the child's home) improves engagement for this population. This study examines the association between the delivery of in-home psychosocial treatment and engagement in services among Medicaid-enrolled youth., Method: We used 2010 to 2014 Georgia Medicaid claims data to identify 53,508 children and adolescents (aged 5-17 years) with a MH diagnosis that initiated new psychosocial treatment. We estimated regression models controlling for covariates to examine the relationship of the receipt of any in-home psychosocial treatment in the home setting with 3 outcome measures of engagement: receipt of at least 4 psychosocial visits during the first 12 weeks; total number of psychosocial visits during the first 12 weeks; and total duration of service use., Results: Those who received any in-home psychosocial treatment (compared to those who did not) had 4.3 times the odds (odds ratio = 4.3, 95% CI = 4.0, 4.7) of receiving at least 4 visits during the first 12 weeks, had 4.5 (95% CI = 4.3, 4.7) more predicted visits during the first 12 weeks, and had a longer treatment episode duration (mean rate ratio = 1.54, 95% CI = 1.48,1.59)., Conclusion: Although many Medicaid-enrolled youth do not receive a sufficient number of MH services to achieve positive outcomes, our findings suggest that providing in-home psychosocial treatment can improve service engagement and potentially help address this challenge., (Copyright © 2022 American Academy of Child and Adolescent Psychiatry.

Background: In this article, the authors addressed shortcomings in existing research on pediatric oral health care access using rigorous data and methods for identifying statistically significant disparities in oral health care access for children., Methods: The study population included children, differentiated by insurance status (Medicaid, Children's Health Insurance Program, private, none). The authors measured provider-level supply as the number of oral health care visits, stratified by provider type and urbanicity-rurality. The authors defined demand as the number of dental visits for children and derived demand and supply mainly from 2019 and 2020 data. Using statistical modeling, the authors evaluated where disparities in travel distance across communities or by insurance status were statistically significant., Results: Although Dental Health Professional Shortage Areas are primarily rural, this study found that the proportions of rural, suburban, and urban communities identified for access interventions ranged from 24% through 66% and from 8% through 86%, respectively. For some states (Florida, Louisiana, Texas), rural and suburban communities showed a need for interventions for all children, whereas in the remaining states, the lack of Medicaid and Children's Health Insurance Program access mainly contributed to these disparities. Variations in access disparities with respect to insurance status across states or by urbanicity-rurality were extensive, with the rate of communities identified for reducing disparities ranging from 1% through 100%., Conclusions: All states showed a need for access interventions and for reducing disparities due to geographic location or insurance status. The sources of disparities were different across states, suggesting need for different policies and interventions across the 10 states., Practical Implications: The study findings support the need for policies toward reducing disparities in oral health care access., (Copyright © 2022 American Dental Association.

Objective: To assess the effect of adolescent birth on the health and wellness of these infants within their first year of life., Methods: Our study focused on 2011 Medicaid births nationwide. The study group (infants born to adolescents, aged 10 to 19 at time of birth) was matched with infants born to adults (aged 20 to 44 at time of birth), based on demographics. Statistical tests (proportion test and Poisson test) were used to compare the outcomes of these two groups to determine if differences were significant., Results: The outcomes assessed were: low birth weight (LBW), substance exposure, foster care, health status, infant mortality, emergency department (ED) visits, and wellness visits. Of the 68,562 infant pairs included in the study, we found statistically significant higher rates of LBW (P ≤ 0·005), infant mortality (P = 0·05), and ED visits (P ≤ 0·005) for infants born to adolescents at the 95% confidence interval. The rate of wellness visits for all infants was well below the recommended amount. Additional differences were found at the race/ethnicity and urbanicity levels., Conclusion for Practice: Infants born to adolescents had a higher rate of ED visits within the first year of life, however, the increased rates of LBW and mortality for the Medicaid population are not as significant as previous national studies suggest. Analysis of outcomes across stratification helped identify vulnerable populations (i.e. urban infants). Public health programs are urged to examine ED visits in infants born to adolescents among the Medicaid population. Improved health education or phone-based resources could help reduce unnecessary visits and reduce cost.

Objective: We estimated the caseload of providers, practices, and clinics for psychosocial services (including psychotherapy) to Medicaid-insured children to improve the understanding of the current supply of such services and to inform opportunities to increase their accessibility., Methods: We used 2012-2013 Medicaid claims data and data from the 2013 National Plan and Provider Enumeration System to identify and locate therapists, psychiatrists, and mental health centers along with primary, rehabilitative, and developmental care providers in the United States who provided psychosocial services to Medicaid-insured children. We estimated the per-provider, per-location, and state-level caseloads of providers offering these services to Medicaid-insured children in 34 states with sufficiently complete data to perform this analysis, by using the most recent year of Medicaid claims data available for each state. We measured caseload by calculating the number of psychosocial visits delivered by each provider in the selected year. We compared caseloads across states, urbanicity, provider specialty (eg, psychiatry, psychology, primary care), and practice setting (eg, mental health center, single practitioner)., Results: We identified 63 314 providers, practices, or centers in the Medicaid claims data that provided psychosocial services to Medicaid-insured children in either 2012 or 2013. The median provider-level per-year caseload was <25 children and <250 visits across all provider types. Providers with a mental health center-related taxonomy accounted for >40% of visits for >30% of patients. Fewer than 10% of providers and locations accounted for >50% of patients and visits., Conclusions: Psychosocial services are concentrated in a few locations, thereby reducing geographic accessibility of providers. Providers should be incentivized to offer care in more locations and to accept more Medicaid-insured patients.

Background . Intensive multidisciplinary intervention (IMI) represents a well-established treatment for pediatric feeding disorders (PFDs), but program availability represents an access care barrier. We develop an economic analysis of IMI for weaning from gastronomy tube (G-tube) treatment for children diagnosed with PFDs from the Medicaid programs' perspective, where Medicaid programs refer to both fee-for-service and managed care programs. Methods . The 2010-2012 Medicaid Analytic eXtract claims provided health care data for children aged 13 to 72 months. An IMI program provided data on average admission costs. We employed a finite-horizon Markov model to simulate PFD treatment progression assuming 2 treatment arms: G-tube only v. IMI targeting G-tube weaning. We compared the expenditure differential between the 2 arms under varying time horizons and treatment effectiveness. Results . Overall Medicaid expenditure per member per month was $6814, $2846, and $1550 for the study population of children with PFDs and G-tube treatment, the control population with PFDs without G-tube treatment, and the no-PFD control population, respectively. The PFD-diagnosed children with G-tube treatment only had the highest overall expenditures across all health care settings except psychological services. The expenditure at the end of the 8-year time horizon was $405,525 and $208,218 per child for the G-tube treatment only and IMI arms, respectively. Median Medicaid expenditure was between 1.7 and 2.2 times higher for the G-tube treatment arm than for the IMI treatment arm. Limitations . Data quality issues could cause overestimates or underestimates of Medicaid expenditure. Conclusions . This study demonstrated the economic benefits of IMI to treat complex PFDs from the perspective of Medicaid programs, indicating this model of care not only holds benefit in terms of improving overall quality of life but also brings significant expenditure savings in the short and long term.

Background: Small-area asthma prevalence measures, which are crucial for targeting interventions, are currently sparsely available for children., Objective: To provide measures of in-contact asthma prevalence for the 2012 Medicaid child population so as to highlight areas in need of targeted asthma interventions., Methods: Using the 2012 Medicaid Analytic eXtract claims files, we developed 2 prevalence metrics differentiated by persistent and diagnosed asthma. We developed prevalence measures at the state, county, and census tract levels, with statistical inferences to highlight areas of high prevalence where interventions should be focused. We compared the measures with asthma prevalence estimates derived from a sample of the child population that self-reported whether they have been diagnosed with asthma regardless of in-contact asthma., Results: A total of 1.98 million (8.1%) and 1.71 million (6.9%) Medicaid-enrolled children were identified with in-contact asthma diagnosis and persistent asthma, respectively. Among 40 states, 17 had lower prevalence estimates for the Medicaid-enrolled children compared with similar child asthma self-reported prevalence estimates from the Centers for Disease Control and Prevention. High-prevalence regions spanned primarily in the southern Midwest region, from Texas to West Virginia and from Illinois to north Florida., Conclusion: There are large variations in the differences between the self-reported estimates from the Centers for Disease Control and Prevention for the general population and the in-contact estimates for the Medicaid-enrolled children, highlighting potential asthma misdiagnosis in the Medicaid population in many states. Small-area estimates point to areas of high prevalence, consistently throughout the south and southeast., (Copyright © 2018 American Academy of Allergy, Asthma & Immunology.

Background: The authors' aims were to compare, according to strata, dentists' participation in Medicaid and Medicaid provider-level caseload measured as the number of patients or visits for preventive or restorative care for 2 comparison years., Methods: The data sources were the 2012-2013 Medicaid Analytic eXtract claims and 2013 National Plan and Provider Enumeration System data sets. The authors measured Medicaid participation as the proportion of dentists participating in Medicaid among those in the National Plan and Provider Enumeration System. The authors measured provider-level caseload according to the number of patients or visits. The authors stratified oral health care providers according to state; whether practicing in rural, suburban, or urban communities; and provider type., Results: The differences in participation rates for rural versus suburban and versus urban communities ranged from -4% through 27% and -6% through 37%, respectively. The 2012 state median number of patients per provider for preventive care ranged from 99 through 358. The provider-level caseload increased from rural to urban and from other provider to general dentist to pediatric dentist. The difference in caseload from 2012 to 2013 was not statistically significant except for the pediatric dentist type., Conclusions: This study's results suggest that the realized caseload for children enrolled in Medicaid varies according to provider type and urbanicity. The state median caseload for preventive care is lower than the 500:1 patient to provider ratio used as the minimum caseload in access estimates from other studies., Practical Implications: This study's results can assist states in gauging the level of oral health care provided to children insured by Medicaid compared with that in other states, with implications for the specification of oral health policies., (Copyright © 2019 American Dental Association.

Introduction: The US Medical Eligibility Criteria for Contraceptive Use (MEC) identified 20 medical conditions that increase a woman's risk for adverse outcomes in pregnancy. MEC recommends that women with these conditions use long-acting, highly effective contraceptive methods. The objective of our study was to examine provision of contraception to women enrolled in Medicaid who had 1 or more of these 20 medical conditions METHODS: We used Medicaid Analytic Extract claims data to study Medicaid-enrolled women who were of reproductive age in the 2-year period before MEC's release (2008 and 2009) (N = 442,424) and the 2-year period after its release (2011 and 2012) (N = 533,619) for 14 states. We assessed 2 outcomes: provision of family planning management (FPM) and provision of highest efficacy methods (HEMs) for the entire study population and by health condition. The ratio of the after-MEC rate to the before-MEC rate was used to determine significance in MEC's uptake., Results: Outcomes increased significantly from the before-MEC period to the after-MEC period for both FPM (1.06; lower bound confidence interval [CI], 1.05) and HEM (1.37; lower bound CI, 1.36) for a 1-sided hypothesis test. For the 19 of 20 conditions we were able to test for FPM, contraceptive use increased significantly for 12 conditions, with ratios ranging from 1.05 to 2.14. For the 16 of 20 conditions tested for HEM, contraception use increased significantly for all conditions, with ratios ranging from 1.19 to 2.80., Conclusion: Provision of both FPM and HEM increased significantly among women with high-risk health conditions from the before-MEC period (2008 and 2009) to the after-MEC period (2011 and 2012). Health policy makers and clinicians need to continue promotion of effective family planning management for women with high-risk conditions.

Objective: Attention-deficit/hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder of childhood. Clinical guidelines recommend behavior therapy as the first-line treatment for preschool-age children with ADHD. This study evaluated longitudinal patterns of services received by Medicaid-enrolled children ages 2 to 5 with ADHD in seven southeastern states (Alabama, Florida, Georgia, Louisiana, Mississippi, North Carolina, and South Carolina)., Methods: A discrete sequence clustering analysis was used with 2005-2012 Medicaid Analytic eXtract data to profile patient-level utilization for each state, with a focus on receipt of psychological services and medication. The model output was used to assess utilization behaviors longitudinally relative to recommended care guidelines and to characterize sources of variation in utilization patterns by demographic and ecological factors., Results: Five states had a utilization profile with a high probability of receipt of psychological services before medication among children with ADHD, covering 16% of the total study population. Most young children's ADHD care experience in the seven states (65%) fit utilization profiles characterized by a high probability of receiving any ADHD medication. Black race was significantly associated with higher utilization of psychological services in three states., Conclusions: About 16% of Medicaid-enrolled preschool-age children with ADHD received care during 2005-2012 that appeared to be consistent with 2011 recommended care guidelines. State-level and subpopulation variations in utilization for ADHD-related clinical care were found. The findings indicate that there were major gaps in treatment for ADHD among young children and that the gaps are wider for some states and subpopulations of children.

Objective: To quantify the impact of multiyear utilization of preventive dental services on downstream dental care utilization and expenditures for children., Data Sources/study Setting: We followed 0.93 million Medicaid-enrolled children who were 3-6 years old in 2005 from 2005 to 2011. We used Medicaid claims data of Alabama, Georgia, Mississippi, North Carolina, South Carolina, and Texas., Study Design: We clustered each state's study population into four groups based on utilization of topical fluoride and dental sealants before caries-related treatment using machine learning algorithms. We evaluated utilization rates and expenditures across the four groups and quantified cost savings of preventive care for different levels of penetration., Data Extraction Method: We extracted all dental-related claims using CDT codes., Principal Findings: In all states, Medicaid expenditures were much lower for children who received topical fluoride and dental sealants before caries development than for all other children, with a per-member per-year difference ranging from $88 for Alabama to $156 for Mississippi., Conclusions: The cost savings from topical fluoride and sealants across the six states ranged from $1.1M/year in Mississippi to $12.9M/year in Texas at a 10 percent penetration level. Preventive dental care for children not only improves oral health outcomes but is also cost saving., (© Health Research and Educational Trust.)

Many studies in health services research rely on regression models with a large number of covariates or predictors. In this article, we introduce novel methodology to estimate and perform model selection for high-dimensional non-parametric multivariate regression problems, with application to many healthcare studies. We particularly focus on multi-responses or multi-task regression models. Because of the complexity of the dependence between predictors and the multiple responses, we exploit model selection approaches that consider various level of groupings between and within responses. The novelty of the method lies in its ability to account simultaneously for between and within group sparsity in the presence of non-linear effects. We also propose a new set of algorithms that can identify inactive and active predictors that are common to all responses or to a subset of responses. Our modeling approach is applied to uncover factors that impact healthcare expenditure for children insured through the Medicaid benefits program. We provide important findings on the association between healthcare expenditure and a large number of well-cited factors for two neighboring states, Georgia and North Carolina, which have similar demographics but different Medicaid systems. We also validate our methods with a benchmark cancer data set and simulated data examples.

Background: This study introduces a framework for analyzing and visualizing health care utilization for millions of children, with a focus on pediatric asthma, one of the major chronic respiratory conditions., Methods: The data source is the 2005 to 2012 Medicaid Analytic Extract claims for 10 Southeast states. The study population consists of Medicaid-enrolled children with persistent asthma. We translate multiyear, individual-level medical claims into sequences of discrete utilization events, which are modeled using Markov renewal processes and model-based clustering. Network analysis is used to visualize utilization profiles. The method is general, allowing the study of other chronic conditions., Results: The study population consists of 1.5 million children with persistent asthma. All states have profiles with high probability of asthma controller medication, as large as 60.6% to 90.2% of the state study population. The probability of consecutive asthma controller prescriptions ranges between 0.75 and 0.95. All states have utilization profiles with uncontrolled asthma with 4.5% to 22.9% of the state study population. The probability for controller medication is larger than for short-term medication after a physician visit but not after an emergency department (ED) visit or hospitalization. Transitions from ED or hospitalization generally have a lower probability into physician office (between 0.11 and 0.38) than into ED or hospitalization (between 0.20 and 0.59)., Conclusions: In most profiles, children who take asthma controller medication do so regularly. Follow-up physician office visits after an ED encounter or hospitalization are observed at a low rate across all states. Finally, all states have a proportion of children who have uncontrolled asthma, meaning they do not take controller medication while they have severe outcomes.

Objective: We evaluated the impact of loan repayment programmes, revising Medicaid fee-for-service rates, and changing dental hygienist supervision requirements on access to preventive dental care for children in Georgia., Methods: We estimated cost savings from the three interventions of preventive care for young children after netting out the intervention cost. We used a regression model to evaluate the impact of changing the Medicaid reimbursement rates. The impact of supervision was evaluated by comparing general and direct supervision in school-based dental sealant programmes., Results: Federal loan repayments to dentists and school-based sealant programmes (SBSPs) had lower intervention costs (with higher potential cost savings) than raising the Medicaid reimbursement rate. General supervision had costs 56% lower than direct supervision of dental hygienists for implementing a SBSP. Raising the Medicaid reimbursement rate by 10 percentage points would improve utilization by <1% and cost over $38 million. Given one parameter set, SBSPs could serve over 27 000 children with an intervention cost between $500 000 and $1.3 million with a potential cost saving of $1.1 million. Loan repayment could serve almost 13 000 children for a cost of $400 000 and a potential cost saving of $176 000., Conclusions: The three interventions all improved met need for preventive dental care. Raising the reimbursement rate alone would marginally affect utilization of Medicaid services but would not substantially increase acceptance of Medicaid by providers. Both loan repayment programmes and amending supervision requirements are potentially cost-saving interventions. Loan repayment programmes provide complete care to targeted areas, while amending supervision requirements of dental hygienists could provide preventive care across the state., (© 2017 John Wiley & Sons A/S.

Introduction: We compared access to preventive dental care among low-income children eligible for public dental insurance to access among children with private dental insurance and/or high family income (>400% of the federal poverty level) in Georgia, and the effect of policies toward increasing access to dental care for low-income children., Methods: We used multiple sources of data (eg, US Census, Georgia Board of Dentistry) to estimate, by census tract, measures of preventive dental care access in 2015 for children aged 0 to 18 years. Measures were percentage of met need, 1-way travel distance to a dentist, and scarcity of dentists. We used an optimization model to estimate access, quantify disparities, and evaluate policies., Results: About 1.5 million children were eligible for public insurance; 600,000 had private insurance and/or high family income. Across census tracts, average met need was 59% for low-income children and 96% for high-income children; for rural census tracts, these values were 33% and 84%, respectively. The average 1-way travel distance for all census tracts was 3.7 miles for high-income and/or privately insured children and 17.2 miles for low-income children; for rural census tracts, these values were 11.6 and 32.9 miles, respectively. Increasing dentists' acceptance of public insurance-eligible children increased met need more in rural areas than in urban areas. To achieve 100% met need in rural tracts, however, an 80% participation rate among dentists would be required., Conclusion: Across census tracts, high-income children had better access to preventive dental care than low-income children had. Identifying tracts with disparities in access could result in more efficient allocation of public health dental resources.

Objectives: To evaluate how met need for accessibility and availability of primary care among nonelderly individuals in Georgia will be affected by the Patient Protection and Affordable Care Act (ACA) over the next 10 years., Methods: We used a stock-and-flow model to predict the number of available visits from 2013 to 2025, regression models to project needed visits, and an optimization model to estimate met need. The outputs of these models were used to estimate unmet need and the availability and accessibility of primary care., Results: Our findings showed that the number of primary care providers will increase by 9.2% to 11.7% by 2025 and that the number of needed visits will increase by 20%. Under Medicaid expansion, the percentage of met need will increase from 67% to 80%. Accessibility will improve by 20% under expansion, and availability will decrease by 13% to 19% under expansion., Conclusions: The ACAs' provisions will reduce unmet need and positively affect accessibility while reducing availability in some communities. Increased need because of a larger Medicaid population under Medicaid expansion will not be a significant burden on the privately insured population.

Objective: This article discusses the sources of overestimation of spatial access as recently provided by the Health Policy Institute (HPI) of the American Dental Association.Methods: Sources of overestimation of access included estimation of Medicaid participation and capacity and limitations of the access measurement approach.Results: While the HPI analysis used a 30% Medicaid acceptance rate for Florida, 10.2% of dentists accepted ≥100 Medicaid patients in 2015. The nationwide median number of Medicaid-enrolled children per provider ranges from 36 (Nebraska) to 265 (Florida). HPI estimated that 94% of publicly insured children in Georgia lived within 15 minutes of participating dentists. More rigorous modeling for access estimated that 23% of the total child population do not have access within the state access standards in Georgia.Conclusions: The estimates provided by HPI substantially overestimate access for children with public insurance. The overestimation comes from both the data limitations and the shortcomings of the methodology employed. [ABSTRACT FROM AUTHOR]

We introduce a modeling approach for characterizing heterogeneity in healthcare utilization using massive medical claims data. We first translate the medical claims observed for a large study population and across five years into individual-level discrete events of care called utilization sequences. We model the utilization sequences using an exponential proportional hazards mixture model to capture heterogeneous behaviors in patients’ healthcare utilization. The objective is to cluster patients according to their longitudinal utilization behaviors and to determine the main drivers of variation in healthcare utilization while controlling for the demographic, geographic, and health characteristics of the patients. Due to the computational infeasibility of fitting a parametric proportional hazards model for high-dimensional, large-sample size data we use an iterative one-step procedure to estimate the model parameters and impute the cluster membership. The approach is used to draw inferences on utilization behaviors of children in the Medicaid system with persistent asthma across six states. We conclude with policy implications for targeted interventions to improve adherence to recommended care practices for pediatric asthma. Supplementary materials for this article are available online.
