Medicaid Managed Care in an Integrated Health Care Delivery System: Lessons from Geisinger's Early Experience

The association between care management and neonatal outcomes: the role of a Medicaid-managed pregnancy medical home in North Carolina

BACKGROUND

Preterm birth is a significant clinical and public health issue in the United States. Rates of preterm birth have remained unchanged, and racial disparities persist. Although a causal pathway has not yet been defined, it is likely that a multitude of clinical and social risk factors contribute to a pregnant person's risk. State-based public health and provider programmatic partnerships have the potential to improve care during pregnancy and reduce complications, such as preterm birth. In North Carolina, a state-based Medicaid-managed Pregnancy Medical Home Program screens pregnant individuals for psychosocial and medical risk factors and utilizes community-based care management, to offer support to those at highest risk.

OBJECTIVE

This study aimed to examine the association between care-management and birth outcomes (low birthweight and preterm birth rates) among high-risk non-Hispanic White and Black pregnant people enrolled in the North Carolina Pregnancy Medical Home.

STUDY DESIGN

This was a quasi-experimental study of people in the Medicaid-managed North Carolina Pregnancy Medical Home who had singleton pregnancies and who enrolled in the program between January 2016 and December 2017. Black and White pregnant people were included in the analysis if they had singleton pregnancies, were enrolled in the Pregnancy Medical Home, and for whom there were data regarding care management involvement. Preterm birth and low birthweight were chosen as the outcomes of interest. Two different methodologies were used to test the effect of care management on outcomes: Method 1 evaluated the effect of intensive care management (≥5 face-to-face visits from a care manager) and Method 2 evaluated the effect of the implementation of a specific risk-stratification system. Chi-squared and multivariate logistic regressions were performed as appropriate.

RESULTS

From January 1, 2016 to December 31, 2017, a total of 3564 singleton pregnancies occurred among non-Hispanic Black and White pregnant Medicaid beneficiaries, who were a part of the Pregnancy Medical Home in North Carolina. White pregnant people comprised 57% and Black pregnant people comprised 43% of the sample. In the Method 1 analysis, intensive care management was significantly associated with reductions in preterm birth and low birthweight among Black and White pregnant people whereas in the Method 2 analysis, the implementation of a risk-stratification score only resulted in a significant reduction among Black pregnant people. In multivariable logistic modeling, race, number of prenatal visits, and intensive care management were all significantly associated with the outcomes of interest.

CONCLUSION

Care management is associated with reductions in preterm birth and low birthweight in the Medicaid-managed Pregnancy Medical Home in North Carolina. This study contributes to a growing body of literature on the role of state-based initiatives in reducing perinatal morbidity. These results are significant as it demonstrates the importance of care coordination and management, in identifying and providing resources for high-risk pregnant people. In the United States, where pregnancy-related outcomes are poor, programs that address the multitude of economic, social, and clinical complexities are becoming increasingly crucial and necessary.

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.

Upstream and downstream revenue of upper gastrointestinal endoscopic ultrasound determined with an episode-of-care approach

Background and study aims  Upper gastrointestinal endoscopic ultrasound (EUS) has clinical advantages that can lead to improved patient outcome. This study seeks to characterize and quantify the upstream and downstream healthcare utilizations and revenues. Patients and methods  A retrospective claims data analysis of upper gastrointestinal EUS procedures was conducted at a large health system. Types of care and total revenues associated with each episode of care were characterized by descriptive statistics. Comparisons were made between patients who had Medicare Advantage and commercial plans as well as those with and without cancer diagnoses during the downstream period. Results  A total of 436 cases were identified. The most frequent downstream healthcare utilizations consisted of radiology (31 %), pathology services (28 %), and high-revenue services including chemotherapy and inpatient admissions. The most common upstream utilizations included radiology (18 %) and lab services (22 %). Average total downstream revenue was $ 34 231 (95 %CI: $ 28 561 - $ 39 901) per case, and average total upstream revenue was $4373 (95 %CI: $3227 - $ 5519). Average total revenue per case did not differ significantly between Medicare Advantage and commercial plan members. However, patients who were diagnosed with cancer at or immediately following EUS (20 %) were associated with significantly higher total revenue compared to those without cancer diagnosis ( P  < 0.0001). Conclusions  This episode-of-care approach to quantifying the revenue impact of upper gastrointestinal EUS to the providers suggests there are substantial downstream as well as upstream revenues associated with upper gastrointestinal EUS procedures, driven by patients who are diagnosed with cancer by the EUS procedures and subsequently require oncologic care.

The Impact of Medicaid Managed Care on Health Service Utilization Among Adults With Intellectual and Developmental Disabilities

People with intellectual and developmental disabilities (IDD) are frequent users of health services. We examined how their service utilization of emergency department (ED), inpatient hospitalization, and primary care physicians changed as they transitioned from fee-for-service to Medicaid managed care (MMC). Our results showed that MMC reduced the utilization of all of these services. A substantial decrease in ED visits was associated with the reduction in visits due to mental/behavioral health conditions and conditions that could be nonemergent and manageable with the community-based health services. These findings suggest that health service utilization of people with IDD is related not only to their health needs, but also to the delivery model that provides their health services.

Do Patient-Centered Medical Homes Improve Health Behaviors, Outcomes, and Experiences of Low-Income Patients? A Systematic Review and Meta-Analysis

OBJECTIVES

To examine: (1) what elements of patient-centered medical homes (PCMHs) are typically provided to low-income populations, (2) whether PCMHs improve health behaviors, experiences, and outcomes for low-income groups.

DATA SOURCES/STUDY SETTING

Existing literature on PCMH utilization among health care organizations serving low-income populations.

STUDY DESIGN

Systematic review and meta-analysis.

DATA COLLECTION/EXTRACTION METHODS

We obtained papers through existing systematic and literature reviews and via PubMed, Web of Science, and the TRIP databases, which examined PCMHs serving low-income populations. A total of 434 studies were reviewed. Thirty-three articles met eligibility criteria.

PRINCIPAL FINDINGS

Patient-centered medical home interventions usually were composed of five of the six recommended components. Overall positive effect of PCMH interventions was d = 0.247 (range -0.965 to 1.42). PCMH patients had better clinical outcomes (d = 0.395), higher adherence (0.392), and lower utilization of emergency rooms (d = -0.248), but there were apparent limitations in study quality.

CONCLUSIONS

Evidence shows that the PCMH model can increase health outcomes among low-income populations. However, limitations to quality include no assessment for confounding variables. Implications are discussed.

New Delivery Model for Rising-Risk Patients: The Forgotten Lot?

BACKGROUND

Shared-risk models encourage providers to engage young patients early. Telemedicine may be well suited for younger, healthier patients although it is unclear how best to incorporate telemedicine into routine clinical care.

INTRODUCTION

We test the assumptions surrounding the use of telemedicine, younger and rising-risk patients, and primary care in ClickWell Care (CWC), a care model developed at our institution for our own accountable care organization.

MATERIALS AND METHODS

CWC's team of physicians and wellness coaches work together to provide comprehensive primary care through in-person, phone, and video visits. This study examines usage of the clinic over its initial year in operation.

RESULTS

1,464 unique patients conducted a total of 3,907 visits. 2,294 (58.7%) visits were completed virtually (1,382 [35.4%] by phone and 912 [23.3%] by video). Patients were more inclined to see the physician in-person for a new visit (1,065 visits [70.5%] vs. 362 [24%] phone and 83 [6%] video) and more likely to see the physician virtually for a return visit (606 [43.2%] phone and 249 [17.7%] video vs. 548 [39.1%] in-person), a statistically significant difference (X² = 306.7, p < 0.00001).

CONCLUSION

This new care model successfully engaged a younger population of patients. However, our data suggest young patients may not be inclined to establish care with a primary care physician virtually and, in fact, choose an initial in-person touch point, although many are willing to conduct return visits virtually. This new model of care could have a large impact on how care is delivered to low- and rising-risk patients.
