Medicaid Managed Care Structures and Care Coordination

Medicaid and the Children's Health Insurance Program: an overview for the pediatric radiologist

In terms of number of beneficiaries, Medicaid is the single largest health insurance program in the US. Along with the Children's Health Insurance Program (CHIP), Medicaid covers nearly half of all births and provides health insurance to nearly half of the children in the country. This article provides a broad introduction to Medicaid and CHIP for the pediatric radiologist with a special focus on topics relevant to pediatric imaging and population health. This includes an overview of Medicaid's structure and eligibility criteria and how it differs from Medicare. The paper examines the means-tested programs within the context of pediatric radiology, reviewing pertinent topics such as the rise of Medicaid managed care plans, Medicaid expansion, the effects of Medicaid on child health, and COVID-19. Beyond the basics of benefits coverage, pediatric radiologists should understand how Medicaid and CHIP financing and reimbursement affect the ability of pediatric practices, radiology groups, and hospitals to provide services for children in a sustainable manner. The paper concludes with an analysis of future opportunities for Medicaid and CHIP.

Concordance of Data on Children's Unmet Health Care Needs Between 2 National Surveys

OBJECTIVE

We used public data from 2 national surveys to determine how survey mode and questionnaire wording potentially impact estimated prevalence and predictors of children's unmet health care needs.

METHODS

Data from 2016-2017 were obtained for the National Health Interview Survey (NHIS), where interviewers ask caregivers about each type of unmet health care need in person, and the National Survey of Children's Health (NSCH), a self-administered questionnaire asking a general question about any unmet health care needs, with subparts about specific types of unmet needs. Weighted proportions and multivariable logistic regression were used to analyze each data set.

RESULTS

The weighted proportion of any unmet health care needs was significantly higher in the NHIS (7.5%; 95% confidence interval [CI], 7.0-8.1; N = 17 723) than in the NSCH (3.3%; 95% CI, 2.9-3.7; N = 65 766). When analyzing specific unmet needs, unmet need for dental care was significantly higher according to the NHIS (4.2% vs 1.9% in the NSCH), as was unmet need for vision care (1.7% vs 0.8%). Conversely, estimates of unmet need for medical care were comparable between the surveys (1.4% and 1.0%). On multivariable analysis, predictors of unmet health care needs, such as being uninsured, had effect sizes of similar magnitude in both surveys.

CONCLUSION

The NHIS design, asking about each type of unmet need in person, may have been more conducive to identifying the full range of unmet health care needs among children. However, our results did not indicate that this was a source of bias in multivariable regression analysis.

State-Level Managed Care Penetration in Medicaid and Rates of Preventive Care Visits for Children

OBJECTIVE

To examine time trends in receipt of Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) services in serial cohorts of Medicaid beneficiaries <21 years, as Medicaid managed care (MMC) was adopted by states.

METHODS

Using annual state-level data from the Centers for Medicare & Medicaid Services, we performed national analyses of Medicaid beneficiaries <21 years from 2000 to 2017. We used generalized linear models to assess the relationship between MMC enrollment and EPSDT encounters, accounting for repeated measures, first at the national level overall and then specifying random effects at the state level.

RESULTS

From 2000 to 2017, there was an increase at the national level in Medicaid beneficiaries <21 years enrolled in MMC, from 65% to 94%. At the national level, for every additional 100 enrollees in MMC there was an associated increase of 36 beneficiaries with an EPSDT visit (95% confidence interval: 19-53; P < .001). When accounting for state-level variation, for every additional 100 enrollees in MMC, there was an increase of 6 beneficiaries with an EPSDT visit (95% confidence interval: 2-10; P = .003). Examining the association between MMC penetration and EPSDT participation within each state, including the 50 states and Washington DC, there were 17 states with a significant positive association between MMC ratio and EPSDT participation, and 6 states with a significant negative association.

CONCLUSIONS

As managed care has become the predominant form of Medicaid coverage, there has been a modest increase in preventive visits as indicated by EPSDT participation, with marked variation across states.

Racial and Ethnic Differences in Managed Care Enrollment Among US Children

This survey study uses data from the 2018 Medical Expenditure Panel Survey Household Component to compare rates of health maintenance organization (HMO) enrollment, by race and ethnicity, for children with commercial and public coverage.

Pediatric complex care and surgery comanagement: Preparation for spinal fusion

The aim of this study is to assess the impact of preoperative comanagement with complex care pediatricians (CCP) on children with neuromuscular scoliosis undergoing spinal fusion. We performed chart review of 79 children aged 5-21 years undergoing spinal fusion 1/2014-6/2016 at a children's hospital, with abstraction of clinical documentation from preoperative health evaluations performed regularly by anesthesiologists and irregularly by a CCP. Preoperative referrals to specialists, labs, tests, and care plans needed last minute for surgical clearance were measured. The mean age at surgery was 14 (SD 3) years; cerebral palsy (64%) was the most common neuromuscular condition. Thirty-nine children (49%) had a preoperative CCP evaluation a median 63 days (interquartile range (IQR) 33-156) before the preanesthesia visit. Children with CCP evaluation had more organ systems affected by coexisting conditions than children without an evaluation (median 11 (IQR 9-12) vs. 8 (IQR 5-11); p < .001). The rate of last-minute care coordination activities required for surgical clearance was lower for children with versus without CCP evaluation (1.8 vs. 3.6). A lower percentage of children with CCP evaluation required last-minute development of new preoperative plans (26% vs. 50%, p = .002). Children with CCP involvement were better prepared for surgery, requiring fewer last-minute care coordination activities for surgical clearance.

Medicaid Managed Care's Effects on Costs, Access, and Quality: An Update

Medicaid is integral to public health because it insures one in five Americans and half of the nation's births. Nearly two-thirds of all Medicaid recipients are currently enrolled in a health maintenance organization (HMO). Proponents of HMOs argue that they can lower costs while maintaining access and quality. We critically reviewed 32 studies on Medicaid managed care (2011-2019). Authors reported state-specific cost savings and instances of increased access or quality with implementation or redesign of Medicaid managed-care programs. Studies on high-risk populations (e.g., disabled) found improvements in quality specific to a state or a high-risk population. A unique model of managed care (i.e., the Oregon Health Plan) was associated with reduced costs and improved access and quality, but results varied by comparison state. New trends in the literature focused on analysis of auto-assignment algorithms, provider networks, and plan quality. More analysis of costs jointly with access/quality is needed, as is research on managing long-term care among elderly and disabled Medicaid recipients.

Antipsychotic Use Among Youth in Foster Care Enrolled in a Specialized Managed Care Organization Intervention

OBJECTIVE

Little is known about whether interventions implemented by specialized Medicaid managed care organizations (MMCOs) contributed to recent stabilization of antipsychotic prescribing to youths in foster care. This study examined a multimodal antipsychotic intervention implemented by a specialized MMCO for youths in foster care with routine mental health screening, health passports, elective psychiatric consultation line, and retrospective drug utilization reviews to determine whether this multimodal intervention significantly reduced antipsychotic dispensing for youths with conditions without US Food and Drug Administration (FDA)-approved indications.

METHOD

Employing a difference-in-differences design, intervention effectiveness for youths in foster care (age 6-17 years) compared with adopted youthss was examined. Analyses were stratified by FDA-indicated conditions, other externalizing conditions, and other internalizing conditions. Outcomes included predicted annual probabilities of any antipsychotic dispensed, antipsychotic dispensed for ≥90 consecutive days, and glucose and lipid testing.

RESULTS

Intervention-enrolled youths with FDA-indicated conditions, relative to comparison youths, experienced a 0.6% reduction in any antipsychotic dispensed and 3.1% increase for ≥90 consecutive days dispensed in the 2 years following implementation, both nonsignificant differences. Youths with other externalizing disorders experienced significant reductions, relative to comparison youths, in any antipsychotic dispensed (-6.3%, p < .001) and in ≥90 consecutive days dispensed (-5.5%, p < .001). Youths with other internalizing disorders experienced a significant reduction, relative to comparison youths, in any antipsychotic dispensed (-7.6%, p < .001) and in ≥90 consecutive days dispensed (-5.1%, p < .001). Glucose and lipid testing increased at statistically comparable rates for both groups.

CONCLUSION

MMCO implementation significantly reduced antipsychotic medications without FDA-indicated conditions prescribed to youths, while not significantly affecting antipsychotic medications prescribed to youths with FDA-indicated conditions.
