Association Between Care Management and Outcomes Among Patients With Complex Needs in Medicare Accountable Care Organizations

The effectiveness of emergency medicine follow-up in attaining closed loop communication and downstream follow-up

BACKGROUND

Utilization of different Electronic Health Records (EHR) impedes communication between Emergency Medicine (EM) and Primary Care Provider (PCP) necessitating study on EM's effectiveness in enabling continuity of care following patient discharge. This study's objective was to evaluate the effectiveness of an EM-based follow-up program using secure email for closed-loop communication and follow-up of incidental findings (IF) after EM discharge.

METHODS

Retrospective study of IFs from two Emergency Departments (ED) and one urgent care between 9/1/20-8/30/21. Preceding day IFs were identified by an EM Quality Assurance (QA) team who then notified the patient's PCP via email. Automated rules-based natural language processing (NLP) of emails linking data to EHRs. Chart reviewing of outcomes included whether closed loop communication was established (via a PCP reply acknowledging IF receipt) and whether follow-up care occurred within 12 months. Multivariate logistic regression models examined factors associated with each outcome.

RESULTS

Of 1781 IF notifications, 62 % were female, 77 % white, and 91 % English speaking. PCP replied to 39.1 %; 64.9 % were ultimately followed-up. Patient and IF characteristics were not associated with PCP reply. PCP tenure and EM/PCP EHR system concordance were associated with higher adjusted Odds Ratio (aOR) of PCP reply (aOR 1.05 [1.04-1.07] vs 2.6 [2.0-3.3]). Laboratory IFs were followed-up more than imaging IFs (aOR 1.94 [1.46-2.6]). EM/PCP Use of same EHR was associated with higher odds of some form of follow-up (aOR: 2.1 [1.7-2.7]).

CONCLUSIONS

While email notifications and using the same EHR improve continuity of care, they are insufficient on their own. More comprehensive solutions are needed to enable EM-PCP communication and patient follow-up.

Social Risks and Health Care Use in Medically Complex Patients

Importance

Integrated health care systems have initiated major investments to identify and address social risks, particularly for patients with multiple medical conditions.

Objective

To evaluate the association of social risks with health care use among patients with complex multimorbidity.

Design, Setting, and Participants

This longitudinal cohort study assessed Kaiser Permanente Northern California (KPNC) patients with (1) moderate medical complexity (defined by high comorbidity score, high risk of hospitalization, and/or prior emergency department [ED] admissions) and (2) high medical complexity (eg, meeting additional criteria, such as ≥7 medications and laboratory evidence of poor disease control).

Exposure

Social risks (eg, requiring medical financial assistance and self-reported social barriers to care).

Main Outcomes and Measures

Inpatient and outpatient health care use during 12 months of follow-up (January 15, 2023, to January 14, 2024).

Results

The sample included 97 252 KPNC patients (mean [SD] age, 69.5 [16] years; 52.1% female; 10.6% Asian, 11.1% Black, 18.3% Hispanic, 54.6% White, and 5.5% other race or ethnicity [eg, American Indian or Alaskan Native, Native Hawaiian or Pacific Islander, multiracial, or unknown race]; and 8.8% insured by Medicaid), including 27 827 with moderate medical complexity (5074 [18.2%] with social risks) and 69 425 with high medical complexity (17 343 [25.0%] with social risks). In fully adjusted models, for moderate medical complexity, social risks were associated with higher odds of inpatient admissions (odds ratio [OR], 1.2; 95% CI, 1.1-1.4), ED visits (OR, 1.2; 95% CI, 1.1-1.3), and mental health visits (OR, 1.2; 95% CI, 1.1-1.3) vs individuals without social risks. Among individuals with high medical complexity, social risks were associated with higher odds of inpatient admissions (OR, 1.2; 95% CI, 1.1-1.2), ED visits (OR, 1.2; 95% CI, 1.1-1.2), and 30-day readmissions (OR, 1.2; 95% CI, 1.1-1.3) and higher odds of mental health visits (OR, 1.3; 95% CI, 1.2-1.3) vs individuals without social risks.

Conclusions and relevance

In this cohort study of individuals with medical complexity, coexisting social risks were associated with substantial downstream health care use. Efforts to reduce use in individuals with complex medical comorbidity could include concurrent efforts to identify and reduce social risks.

The Impact of Structural Racism on Continuity of Care at Pediatric Academic Primary Care Clinics

OBJECTIVE

Using a structural racism framework, we assessed racial inequities in continuity of care, using the Usual Provider Continuity Index (UPC - the proportion of visits with the provider the patient saw most frequently out of all visits), in a set of large pediatric academic clinics.

METHODS

We conducted a retrospective cohort study. Patients 12-24 months seen at three pediatric academic primary care clinics for any visit during October 1-31, 2021 were included. We then reviewed continuity for these patients in the preceding 12 months. Outcomes included each patient's UPC for all visits, and a modified UPC for well child checks only (UPC Well). Covariates included race, ethnicity, insurance, clinic site, age, sex, care management, or seeing a social worker. We evaluated for differences in outcomes using bivariate analyses and multivariable regression models.

RESULTS

Our cohort included 356 patients (74% Black, 5% Hispanic, 85% Medicaid, 52% female, median age 15.8 months). The median UPC was 0.33 and median UPC Well was 0.40. Black patients had significantly lower median values for UPC (0.33 Black vs 0.40 non-Black, P < .01) and UPC Well (0.33 Black vs 0.50 non-Black, P < .01). There were similar inequities in continuity rates by insurance and clinic site. In multivariable models, clinic site was the only variable significantly associated with continuity.

CONCLUSIONS

Clinic sites serving higher percentages of Black patients had lower rates of continuity. The main driver of racial inequities in continuity rates was at the institutional level.

Telehealth Infrastructure, Accountable Care Organization, and Medicare Payment for Patients with Alzheimer's Disease and Related Dementia Living in Socially Vulnerable Areas

Background: Structural social determinants of health have an accumulated negative impact on physical and mental health. Evidence is needed to understand whether emerging health information technology and innovative payment models can help address such structural social determinants for patients with complex health needs, such as Alzheimer's disease and related dementias (ADRD). Objective: This study aimed to test whether telehealth for care coordination and Accountable Care Organization (ACO) enrollment for residents in the most disadvantaged areas, particularly those with ADRD, was associated with reduced Medicare payment. Methods: The study used the merged data set of 2020 Centers for Medicare and Medicaid Services Medicare inpatient claims data, the Medicare Beneficiary Summary File, the Medicare Shared Savings Program ACO, the Center for Medicare and Medicaid Service's Social Vulnerability Index (SVI), and the American Hospital Annual Survey. Our study focused on community-dwelling Medicare fee-for-service beneficiaries aged 65 years and up. Cross-sectional analyses and generalized linear models (GLM) were implemented. Analyses were implemented from November 2023 to February 2024. Results: Medicare fee-for-service beneficiaries residing in SVI Q4 (i.e., the most vulnerable areas) reported significantly higher total Medicare costs and were least likely to be treated in hospitals that provided telehealth post-discharge services or have ACO affiliation. Meanwhile, the proportion of the population with ADRD was the highest in SVI Q4 compared with other SVI levels. The GLM regression results showed that hospital telehealth post-discharge infrastructure, patient ACO affiliation, SVI Q4, and ADRD were significantly associated with higher Medicare payments. However, coefficients of interaction terms among these factors were significantly negative. For example, the average interaction effect of telehealth post-discharge and ACO, SVI Q4, and ADRD on Medicare payment was -$1,766.2 (95% confidence interval: -$2,576.4 to -$976). Conclusions: Our results suggested that the combination of telehealth post-discharge and ACO financial incentives that promote care coordination is promising to reduce the Medicare cost burden among patients with ADRD living in socially vulnerable areas.

Health Care Contact Days Among Older Cancer Survivors

PURPOSE

Health care contact days-days spent receiving health care outside the home-represent an intuitive, practical, and person-centered measure of time consumed by health care.

METHODS

We linked 2019 Medicare Current Beneficiary Survey and traditional Medicare claims data for community-dwelling older adults with a history of cancer. We identified contact days (ie, spent in a hospital, emergency department, skilled nursing facility, or inpatient hospice or receiving ambulatory care including an office visit, procedure, treatment, imaging, or test) and described patterns of total and ambulatory contact days. Using weighted Poisson regression models, we identified factors associated with contact days.

RESULTS

We included 1,168 older adults representing 4.51 million cancer survivors (median age, 76.4 years, 52.8% women). The median (IQR) time from cancer diagnosis was 65 (27-126) months. In 2019, these adults had mean (standard deviation) total contact days of 28.4 (27.6) and ambulatory contact days of 24.2 (23.6). These included days for tests (8.0 [8.8]), imaging (3.6 [4.1]), visits with any clinicians (12.4 [11.5]), and visits with primary care clinicians (4.4 [4.7]), and nononcology specialists (7.1 [9.4]) specifically. Sixty-four percent of days with a nonvisit ambulatory service (eg, a test) were not on the same day as a clinician visit. Factors associated with more total contact days included younger age, lower income, more chronic conditions, poor self-rated health, and tendency to "go to doctor as soon as feel bad."

CONCLUSION

Older adult cancer survivors spent nearly 1 month of the year receiving health care outside the home. This care was largely ambulatory, often delivered by nononcologists, and varied by factors beyond clinical characteristics. These results highlight the need to recognize patient burdens and improve survivorship care delivery, including through care coordination.

Healthcare contact days among older adults living with dementia

BACKGROUND

For older adults with dementia and their care partners, accessing health care outside the home involves substantial time, direct and indirect costs, and other burdens. While prior studies have estimated days spent by these individuals in or out of hospitals and nursing homes, ambulatory care burdens are likely substantial yet poorly understand. Therefore, we characterized "health care contact days"-days spent receiving ambulatory or institutional care-in this population.

METHODS

We used 2019 Medicare Current Beneficiary Survey data linked to claims for community-dwelling, ≥65-year-old adults with dementia in Traditional Medicare. We measured contact days including ambulatory days (with an office visit, test, imaging, procedure, or treatment) and institutional days (spent in an emergency department, hospital, skilled nursing facility, or hospice facility). We described variation and patterns in contact days. Using multivariable Poisson regression, we identified sociodemographic and clinical factors associated with contact days.

RESULTS

In weighted analyses, 887 older adults with dementia (weighted: 2.9 million) had mean (SD) 31.1 (33.7) total contact days/year, of which 21.7 (20.6) were ambulatory. Ten percent had ≥68 contact days in the year. One-third (34%) of ambulatory contact days involved multiple services. In multivariable models, receipt of more ambulatory contact days was associated with younger age (65-74 reference vs. -32.3% [95% CI: -42.2%, -20.7%] for 85+), higher income (>200% Federal Poverty Level [FPL] reference versus -16.6% [95% CI: -26.7%, -5.0%] for ≤200% FPL), and lack of functional impairment (reference versus -14.6% [95% CI: -23.7%, -4.4%]). Each additional chronic condition was associated with 8.2% (95% CI: 6.7%, 9.8%) more ambulatory contact days.

CONCLUSIONS

Older adults with dementia spent 31 days a year accessing care which was mostly ambulatory. These days varied widely by both clinical and sociodemographic factors. These results highlight the need to reduce patient burden through strategies such as reducing unneeded care, coordinating care, and shifting care to home settings through telemedicine and home care.

Health Care Contact Days Among Older Adults in Traditional Medicare : A Cross-Sectional Study

BACKGROUND

Days spent obtaining health care outside the home can represent not only access to needed care but also substantial time, effort, and cost, especially for older adults and their care partners. Yet, these "health care contact days" have not been characterized.

OBJECTIVE

To assess composition of, variation and patterns in, and factors associated with contact days among older adults.

DESIGN

Cross-sectional study.

SETTING

Nationally representative 2019 Medicare Current Beneficiary Survey data linked to claims.

PARTICIPANTS

Community-dwelling adults aged 65 years and older in traditional Medicare.

MEASUREMENTS

Ambulatory contact days (days with a primary care or specialty care office visit, test, imaging, procedure, or treatment) and total contact days (ambulatory days plus institutional days in a hospital, emergency department, skilled-nursing facility, or hospice facility); multivariable mixed-effects Poisson regression to identify patient factors associated with contact days.

RESULTS

In weighted results, 6619 older adults (weighted: 29 694 084) had means of 17.3 ambulatory contact days (SD, 22.1) and 20.7 total contact days (SD, 27.5) in the year; 11.1% had 50 or more total contact days. Older adults spent most contact days on ambulatory care, including primary care visits (mean [SD], 3.5 [5.0]), specialty care visits (5.7 [9.6]), tests (5.3 [7.2]), imaging (2.6 [3.9]), procedures (2.5 [6.4]), and treatments (5.7 [13.3]). Half of the test and imaging days were not on the same days as office visits (48.6% and 50.1%, respectively). Factors associated with more ambulatory contact days included younger age, female sex, White race, non-Hispanic ethnicity, higher income, higher educational attainment, urban residence, more chronic conditions, and care-seeking behaviors (for example, "go to the doctor…as soon as (I)…feel bad").

LIMITATION

Study population limited to those in traditional Medicare.

CONCLUSION

On average, older adults spent 3 weeks in the year getting care outside the home. These contact days were mostly ambulatory and varied widely not only by number of chronic conditions but also by sociodemographic factors, geography, and care-seeking behaviors. These results show factors beyond clinical need that may drive overuse and underuse of contact days and opportunities to optimize this person-centered measure to reduce patient burdens, for example, via care coordination.

Practice Site Heterogeneity within and between Medicaid Accountable Care Organizations

The existing literature has considered accountable care organizations (ACOs) as whole entities, neglecting potentially important variations in the characteristics and experiences of the individual practice sites that comprise them. In this observational cross-sectional study, our aim is to characterize the experience, capacity, and process heterogeneity at the practice site level within and between Medicaid ACOs, drawing on the Massachusetts Medicaid and Children's Health Insurance Program (MassHealth), which launched an ACO reform effort in 2018. We used a 2019 survey of a representative sample of administrators from practice sites participating in Medicaid ACOs in Massachusetts (n = 225). We quantified the clustering of responses by practice site within all 17 Medicaid ACOs in Massachusetts for measures of process change, previous experience with alternative payment models, and changes in the practices' ability to deliver high-quality care. Using multilevel logistic models, we calculated median odds ratios (MORs) and intraclass correlation coefficients (ICCs) to quantify the variation within and between ACOs for each measure. We found greater heterogeneity within the ACOs than between them for all measures, regardless of practice site and ACO characteristics (all ICCs ≤ 0.26). Our research indicates diverse experience with, and capacity for, implementing ACO initiatives across practice sites in Medicaid ACOs. Future research and program design should account for characteristics of practice sites within ACOs.

Reducing Rural and Urban Disparities in Potentially Preventable Hospitalizations: Evidence of Hospital-Based Health Information Technology and Enabling Services

Background: Telehealth and enabling services are promising approaches to address the intersecting challenges of chronic disease burden, a growing aging population, and poor access to care disproportionately affecting rural areas. Using potentially preventable hospitalizations (PPHs) as an indicator for health system efficiency and quality, this study examined the relationship between health information technology and hospital-provided enabling services on PPHs across rural, micropolitan, and metropolitan areas. Methods: We constructed a patient-, hospital-, community-, and state-level data set using the Medicare fee-for-service claims file and the Medicare Master Beneficiary Summary File, and the American Hospital Association Annual Survey. Logistic regressions were applied to examine associations between PPH and telehealth post-discharge, telehealth treatment, and telehealth post-discharge and enabling services. Results: Approximately 50% of rural and micropolitan residents (vs. 36% of urban residents) were treated in hospitals providing neither telehealth post-discharge services nor enabling services, and 7% (vs. 11% of urban residents) were treated in hospitals with both services. Telehealth post-discharge services were associated with significantly lower odds ratio (OR) of having any PPH due to acute (OR = 0.91, p < 0.001) and chronic conditions (OR = 0.94, p < 0.001). The ORs of having any PPH due to acute and chronic conditions were the least among beneficiaries who were treated in hospitals with both telehealth post-discharge and enabling services (OR = 0.56, p < 0.001, for acute conditions, and OR = 0.73, p < 0.001, for chronic conditions). Conclusions: Hospital use of post-discharge telehealth alongside enabling services may help provide timely access to care, improve care coordination, and reduce PPHs for older rural residents.

Challenges in predicting future high-cost patients for care management interventions

BACKGROUND

To test the accuracy of a segmentation approach using claims data to predict Medicare beneficiaries most likely to be hospitalized in a subsequent year.

METHODS

This article uses a 100-percent sample of Medicare beneficiaries from 2017 to 2018. This analysis is designed to illustrate the actuarial limitations of person-centered risk segmentation by looking at the number and rate of hospitalizations for progressively narrower segments of heart failure patients and a national fee-for-service comparison group. Cohorts are defined using 2017 data and then 2018 hospitalization rates are shown graphically.

RESULTS

As the segments get narrower, the 2018 hospitalization rates increased, but the percentage of total Medicare FFS hospitalizations accounted for went down. In all three segments and the total Medicare FFS population, more than half of all patients did not have a hospitalization in 2018.

CONCLUSIONS

With the difficulty of identifying future high utilizing beneficiaries, health systems should consider the addition of clinician input and 'light touch' monitoring activities to improve the prediction of high-need, high-cost cohorts. It may also be beneficial to develop systemic strategies to manage utilization and steer beneficiaries to efficient providers rather than targeting individual patients.

US practice adoption of patient-engagement strategies and spending for adults with diabetes and cardiovascular disease

Patient-engagement strategies are being encouraged by payers and governments, but with limited evidence about whether practice adoption of these strategies impacts utilization and spending. We examine the association of physician practice adoption of patient-engagement strategies (low vs moderate vs high) with potentially preventable utilization and total spending for patients with type 2 diabetes and/or cardiovascular disease using US physician practice survey (n = 2086) and Medicare fee-for-service (n = 736 269) data. In adjusted analyses, there were no differences in potentially preventable utilization associated with practice adoption of patient-engagement strategies. Compared with patients attributed to practices with moderate adoption, patients attributed to practices with high adoption had higher total spending ($26 364 vs $25 991; P < .05) driven by spending for long-term services and supports, including home health agency, long-term care, skilled nursing facilities, and hospice payments. In contrast, patients attributed to practices with low adoption had higher total spending ($26 481 vs $25 991; P < .01) driven by spending for tests and acute care and clinical access spending. The results highlight that stakeholders that encourage the use of patient-engagement strategies should not necessarily expect reduced spending.

Evaluating a Care Management Program for Dual-Eligible Beneficiaries: Evidence from Rhode Island

As health systems attempt to contain utilization and costs, care management programs are proliferating. However, there are mixed findings on their impact. In 2018, Rhode Island initiated a care management program for dually eligible Medicare and Medicaid beneficiaries at high risk of hospitalization or institutionalization. The objective of this study is to evaluate the association between health care utilization and costs and care management for dual-eligible participants (n = 169). The authors employed an interrupted time series analysis of administrative claims data using the Rhode Island All Payer Claims Database, which includes data from all major payers in the state, for 11 quarters (January 1, 2017 until September 1, 2019). On average, participants were younger (46.2% were 19-64 years of age vs. 41.9% of non-participants), female (71% vs. 62.6% of non-participants), and had a higher comorbidity burden (more commonly had anemia, atrial fibrillation, chronic kidney disease, chronic obstructive pulmonary disease, depression, diabetes, heart failure, hyperlipidemia, hypertension, ischemic heart disease, and stroke). Participation was associated with significantly fewer hospital admissions (118 fewer admissions per 1000 admissions per quarter; 95% confidence interval [CI] -11 to -22), and a reduction in Medicaid ($1841 less spent per quarter, 95% CI -2407 to -1275) and total ($2570 less spent per quarter; 95% CI -$4645 to -$495) costs. Participation was not significantly associated with a change in Emergency Department (ED) visits, preventable ED visits, Skilled Nursing Facility stays, or Medicare costs. These results suggest that targeted care management programs may provide dual-eligible beneficiaries with needed services while diverting inefficient health care utilization.

Primary Care Practice Structural Capabilities and Emergency Department Utilization Among High-Need High-Cost Patients

BACKGROUND

US primary care practices are actively identifying strategies to improve outcomes and reduce costs among high-need high-cost (HNHC) patients. HNHC patients are adults with high health care utilization who suffer from multiple chronic medical and behavioral health conditions such as depression or substance abuse. HNHC patients with behavioral health conditions face heightened challenges accessing timely primary care and managing their conditions, which is reflected by their high rates of emergency department (ED) utilization and preventable spending. Structural capabilities (i.e., care coordination, chronic disease registries, shared communication systems, and after-hours care) are key attributes of primary care practices which can enhance access and quality of chronic care delivery.

OBJECTIVE

The purpose of this study was to analyze the association between structural capabilities and ED utilization among HNHC patients with behavioral health conditions.

DESIGN AND MEASURES

We merged cross-sectional survey data on structural capabilities from 240 primary care practices in Arizona and Washington linked with Medicare claims data on 70,182 HNHC patients from 2019.

KEY RESULTS

Using multivariable Poisson models, we found shared communication systems were associated with lower rates of all-cause and preventable ED utilization among HNHC patients with alcohol use (all-cause: aRR 0.72, 95% CI: 0.62, 0.84; preventable: aRR 0.5, 95% CI: 0.40, 0.64) and HNHC patients with substance use disorders (all-cause: aRR 0.76, 95% CI: 0.68, 0.85; preventable: aRR 0.61, 95% CI: 0.52, 0.71). Care coordination was also associated with decreased rates of ED utilization among the overall HNHC population and those with alcohol use, but not among HNHC patients with depression or substance use disorders.

CONCLUSION

Shared communication systems and care coordination have the potential to increase the effectiveness of primary care delivery for specific HNHC patients.

Expectations of the Ontario Healthcare System following the Implementation of Ontario Health Teams

With the arrival of Ontario Health Teams (OHTs), healthcare providers, clinicians and patients seek to witness the efficacy of an integrated care model. OHTs are built on the concept of healthcare integration, coordinated care, shared fiscal and clinical accountabilities between multiple healthcare service providers, as well as bridging the gaps between the clinical, social and health promotional aspects of care delivery. This meta-narrative review seeks to examine, compare and determine the efficacy of the integrated care model using cross-sectional studies from around the world to see how integrated care effects health related outcomes. The efficacy of the model will be determined by evaluating the abilities of other integrated care models to reduce healthcare expenditures, improve coordination of care between healthcare service providers, bolster patient satisfaction and health outcomes, minimise emergency and life-threatening cases, lower emergency hospital admission rates as well as provide a comprehensive set of healthcare services including biomedical, mental and social supports. For future applications, this study could be used as a guideline to highlight areas of improvement in integrated care models, as well as to evaluate benefits of existing models and determine best approaches forward.

Comparison of Health Care Utilization by Medicare Advantage and Traditional Medicare Beneficiaries With Complex Care Needs

Importance

Medicare beneficiaries with co-occurring chronic conditions and complex care needs experience high rates of acute care utilization and poor outcomes. These patterns are well described among traditional Medicare (TM) beneficiaries, but less is known about outcomes among Medicare Advantage (MA) beneficiaries. Compared with TM, MA plans have additional levers to potentially address beneficiary needs, such as network design, care management, supplemental benefits, and value-based contracting.

Objective

To compare health care utilization for MA and TM beneficiaries with complex care needs.

Design, Setting, and Participants

This cross-sectional study analyzed beneficiaries enrolled in MA and TM using claims data from a large, national MA insurer and a random 5% sample of TM beneficiaries. Beneficiaries were segmented into the following cohorts: frail elderly, major complex chronic, and minor complex chronic. Regression models estimated the association between MA enrollment and health care utilization in 2018, using inverse probability of treatment weighting to balance the MA and TM cohorts on observable characteristics. The study period was January 1, 2017, through December 31, 2018. All analyses were conducted from December 2020 to August 2022.

Exposures

Enrollment in MA vs TM.

Main Outcomes and Measures

Hospital stays (inpatient admissions and observation stays), emergency department (ED) visits, and 30-day readmissions.

Results

Among a study population of 1 844 326 Medicare beneficiaries (mean [SD] age, 75.6 [7.1] years; 1 021 479 [55.4%] women; 1 524 458 [82.7%] White; 223 377 [12.1%] with Medicare-Medicaid dual eligibility), 1 177 896 (63.9%) were enrolled in MA and 666 430 (36.1%) in TM. Beneficiary distribution across cohorts was as follows: frail elderly, 116 047 with MA (10.0% of the MA sample) and 104 036 with TM (15.6% of the TM sample); major complex chronic, 320 954 (27.2%) and 158 811 (23.8%), respectively; and minor complex chronic, 740 895 (62.9%) and 403 583 (60.6%), respectively. Beneficiaries enrolled in MA had lower rates of hospital stays, ED visits, and 30-day readmissions. The largest relative differences were observed for hospital stays, which ranged from -9.3% (95% CI, -10.9% to -7.7%) for the frail elderly cohort to -11.9% (95% CI, -13.2% to -10.7%) for the major complex chronic cohort.

Conclusions and Relevance

In this cross-sectional study of Medicare beneficiaries with complex care needs, those enrolled in MA had lower rates of hospital stays, ED visits, and 30-day readmissions than similar beneficiaries enrolled in TM, suggesting that managed care activities in MA may influence the nature and quality of care provided to these beneficiaries.

Rural and urban disparities in potentially preventable hospitalizations among US patients with Alzheimer's Disease and Related Dementias: Evidence of hospital-based telehealth and enabling services

We examined urban and rural disparities in potentially preventable hospitalizations (PPHs) among US patients with Alzheimer's Disease and Related Dementias (ADRD) and the use of telehealth post-discharge and enabling services as mediators. We merged 2017 100% Medicare Fee-For-Service (FFS) claims with the Medicare Beneficiary Summary File, along with population and hospital-based characteristics. Logistic regression models were employed to examine differences in PPHs by telehealth and enabling services. The rates of PPHs related to acute and chronic conditions for patients with ADRD living in rural and micropolitan areas were significantly higher compared to patients with ADRD in urban areas. Telehealth post-discharge combined with enabling services significantly decreased the odds of PPHs associated with acute (OR: 0.93, 95% CI: 0.89-0.98, P-value <0.01) and chronic conditions (OR: 0.96, 95% CI: 0.92-1.00, P-value = 0.07). In addition, telehealth post-discharge combined with enabling services significantly decreased the odds of PPHs in patients with ADRD in rural (acute PPHs OR: 0.56, 95% CI: 0.41-0.77, P-value <0.01; chronic PPHs OR: 0.73, 95% CI: 0.55-0.97, P-value = 0.03) and micropolitan (acute PPHs OR: 0.65, 95% CI: 0.57-0.73, P-value <0.01; chronic PPHs OR: 0.83, 95% CI: 0.74-0.93, P-value <0.01) areas. Our results suggest that the combinations of telehealth post-discharge and enabling services are important interventions in helping to reduce preventable hospitalizations among patients with ADRD living in rural and micropolitan areas.

Changes in spending, utilization, and quality of care among Medicare accountable care organizations during the COVID-19 pandemic

The COVID pandemic disrupted health care spending and utilization, and the Medicare Shared Savings Program (MSSP), Medicare's largest value-based payment model with 11.2 million assigned beneficiaries, was no exception. Despite COVID, the 513 accountable care organizations (ACO) in MSSP returned a program record $1.9 billion in net savings to Medicare in 2020. To understand the extent of COVID's impact on MSSP cost and quality, we describe how ACO spending changed in 2020 and further analyze changes in measured quality and utilization. We found that non-COVID per capita spending in MSSP fell by 8.3 percent from $11,496 to $10,537 (95% confidence interval(CI),-1,223.8 to-695.4, p<0.001), driven by 14.6% and 7.5% reductions in per capita acute inpatient and outpatient spending, respectively. Utilization fell across inpatient, emergency, and outpatient settings. On quality metrics, preventive screening rates remained stable or improved, while control of diabetes and blood pressure worsened. Large reductions in non-COVID utilization helped ACOs succeed financially in 2020, but worsening chronic disease measures are concerning. The appropriateness of the benchmark methodology and exclusion of COVID-related spending, especially as the virus approaches endemicity, should be revisited to ensure bonus payments reflect advances in care delivery and health outcomes rather than COVID-related shifts in spending and utilization patterns.

Access to mental health support services in Accountable Care Organizations: A national survey

Patients with serious mental illness often lack access to mental health support services. Whether new payment models facilitate access to these services is unknown. We conducted a national survey of accountable care organizations(ACOs) and find that fewer than 50% of ACOs surveyed reported that they have the ability to offer or refer patients to supported employment, family psychoeducation, assertive community treatment and illness, management and recovery services. These findings suggest that even among organizations that are early adopters of payment and delivery reforms -- those most likely to lead innovations in population health -- access to these services is limited.

Remote care management for older adult populations with elevated prevalence of depression or anxiety and comorbid chronic medical illness: A systematic review

BACKGROUND

Comorbidity of psychiatric and medical illnesses among older adult populations is highly prevalent and associated with adverse outcomes. Care management is a common form of outpatient support for both psychiatric and medical conditions in which assessment, care planning, and care coordination are provided. Although care management is often remote and delivered by telephone, the evidence supporting this model of care is uncertain.

OBJECTIVE

To perform a systematic review of the literature on remote care management programs for older adult populations with elevated prevalence of depression or anxiety and comorbid chronic medical illness.

METHODS

A systematic review was performed in accordance with PRISMA guidelines. A multi-database search was performed. Articles were included for review if they studied fully remote care management for older adult populations with elevated prevalence of depression or anxiety and chronic medical illness or poor physical health. A narrative synthesis was performed.

RESULTS

A total of 6 articles representing 6 unique studies met inclusion criteria. The 6 studies included 4 randomized controlled trials, 1 case-matched retrospective cohort study, and 1 pre-post analysis. Two studies focused on specific medical conditions. All interventions were entirely telephonic. Five of 6 studies involved an intervention that was 3 to 6 months in duration. Across the 6 studies, care management demonstrated mixed results in terms of impact on psychiatric outcomes and limited impact on medical outcomes. No studies demonstrated a statistically significant impact on health care utilization or cost.

CONCLUSION

Among older adult populations with elevated prevalence of depression or anxiety and comorbid chronic medical illness, remote care management may have favorable impact on psychiatric symptoms, but impact on physical health and health care utilization is uncertain. Future research should focus on identifying effective models and elements of remote care management for this population, with a particular focus on optimizing medical outcomes.

[10 Years Accountable Care Organizations in the USA: Impulses for Health Care Reform in Germany?]

GOAL OF THE STUDY

An intent of the Patient Protection and Affordable Care Acts (ACA), also know as Obama Care, was to slow the expenditure growth in the public Medicare-System by shifting the accountability for health care outcomes and costs to the provider. For this purpose, provider were allowed to form networks, which would then take accountability for a defined population - Accountable Care Organizations (ACOs). Ten years after the introduction of ACOs, this paper looks at the impact of ACOs both on quality of care and costs of care to assess if ACOs can be a model of care delivery for Germany.

METHODS

In a mixed-method approach, a rapid review was conducted in Health System Evidence and PubMed. This was supported with further papers identified using the snowballing-technique. After screening the abstracts, we included articles containing information on cost- and/or quality impact of US-Medicare-ACOs. The findings of the rapid review were challenged with 16 ACO-experts and stakeholder in the USA.

RESULTS

In total, we included 60 publications which incorporated 6 reports that were either conducted directly by governmental institutions or ordered by them, along with 3 previous reviews. Among these, 31 contained information on costs of care, 18 contained information on quality of care and 11 had information on both aspects. The publications show that ACOs reduced costs of of care. Cost reductions were achieved compared to historic costs, to populations not cared for in ACOs, and counterfactuals. Quality of care stayed the same or improved.

CONCLUSION

ACOs contributed to slowing the cost growth in US Medicare without compromising quality of care. Thus, a transferal of this model of care to Germany should be considered. However, various policies have led to ACOs failing to unleash their full potential. Against this background, and against the background of stark differences between US Medicare and the German health care system, a critical reflection of the necessary policies underlying ACOs-like structures in Germany, needs to be undertaken.

Care Management for Serious Mental Illness: A Systematic Review and Meta-Analysis

OBJECTIVE

Persons with serious mental illness face adverse psychiatric and medical outcomes, and their care is associated with a large burden of health care costs. Care management, in which assessment, care planning, and care coordination are provided, is a common model of support, yet the evidence supporting its use among psychiatric populations is mixed. A systematic review and a meta-analysis were undertaken to determine the impact of care management on clinical outcomes, acute care utilization, cost, and satisfaction among adults with serious mental illness.

METHODS

A multidatabase literature search was performed. Articles were included if they compared standard outpatient care plus care management with standard outpatient care alone for adults with serious mental illness and reported on one or more predefined outcomes. Randomized controlled trials (RCTs) and other study designs were permitted for inclusion in the systematic review. The meta-analysis included only RCTs.

RESULTS

For the systematic review, 34 articles representing 28 unique studies were included. Fifteen of these articles, representing 12 unique studies, were included in the meta-analysis, which indicated that care management was associated with small, statistically significant improvements in psychiatric symptoms, overall quality of life (QOL), and mental QOL (Hedges' g range 0.13-0.26). In addition, care management was associated with a small, statistically significant reduction in inpatient psychiatric hospital days (Hedges' g=0.16, p=0.02).

CONCLUSIONS

Care management is associated with fewer psychiatric symptoms and greater QOL for persons with serious mental illness. Further work is needed to determine which components of the intervention are associated with effectiveness.

Value-Based Care and Kidney Disease: Emergence and Future Opportunities

The United States health care system has increasingly embraced value-based programs that reward improved outcomes and lower costs. Health care value, defined as quality per unit cost, was a major goal of the 2010 Patient Protection and Affordable Care Act amid high and rising US health care expenditures. Many early value-based programs were specifically designed for patients with end-stage renal disease (ESRD) and targeted toward dialysis facilities, including the ESRD Prospective Payment System, ESRD Quality Incentive Program, and ESRD Seamless Care Organizations. While a great deal of attention has been paid to these ESRD-focused programs, other value-based programs targeted toward hospitals and health systems may also affect the quality and costs of care for a broader population of patients with kidney disease. Value-based care for kidney disease is increasingly relevant in light of the Advancing American Kidney Health initiative, which introduces new value-based payment models: the mandatory ESRD Treatment Choices Model in 2021 and voluntary Kidney Care Choices Model in 2022. In this review article, we summarize the emergence and impact of value-based programs on the quality and costs of kidney care, with a focus on federal programs. Key opportunities in value-based kidney care include shifting the focus toward chronic kidney disease, enhancing population health management capabilities, improving quality measurement, and leveraging programs to advance health equity.

Aligning care with the personal values of patients with complex care needs

OBJECTIVE

To identify opportunities to align care with the personal values of patients from three distinct groups with complex medical, behavioral, and social needs.

DATA SOURCES/STUDY SETTING

Between June and August 2019, we conducted semi-structured interviews with individuals with complex care needs in two integrated health care delivery systems.

STUDY DESIGN

Qualitative study using semi-structured interviews.

DATA COLLECTION METHODS

We interviewed three groups of patients at Kaiser Permanente Washington and Kaiser Permanente Colorado representing three distinct profiles of complex care needs: Group A ("obesity, opioid prescription, and low-resourced neighborhood"), Group B ("older, high medical morbidity, emergency department, and hospital use"), and Group C ("older, mental and physical health concerns, and low-resourced neighborhood"). These profiles were identified based on prior work and prioritized by internal primary care stakeholders. Interview transcripts were analyzed using thematic analysis.

PRINCIPAL FINDINGS

Twenty-four patients participated; eight from each complex needs profile. Mean age across groups was 71 (range 48-86) years. We identified five themes common across the three groups that captured patients' views regarding values-aligned care. These themes focused on the importance of care teams exploring and acknowledging a patient's values, providing access to nonphysician providers who have different perspectives on care delivery, offering values-aligned mental health care, ensuring connection to community-based resources that support values and address needs, and providing care that supports the patient plus their family and caregivers.

CONCLUSIONS

Our results suggest several opportunities to improve how care is delivered to patients with different complex medical, behavioral, and social needs. Future research is needed to better understand how to incorporate these opportunities into health care.

Organizational Capacity of Hospitals Co-Participating in Accountable Care Organizations and Bundled Payments

Building organizational capacity is critical for hospitals participating in payment models such as bundled payments and accountable care organizations, particularly "co-participant" hospitals with experience in both models. This study used a national survey of American Hospital Association member hospitals with bundled payment experience, with (co-participant hospitals) or without (bundled payment hospitals) accountable care organization experience. Questions examined capacity in 4 domains: performance feedback, postacute care provider utilization, care management, and health information technology. Of 424 hospitals, 38% responded. Both co-participant and bundled payment hospitals reported high capacity for performance feedback and risk stratification and predictive risk assessment using health information technology systems. The hospital groups did not differ in care management capacity, but bundled payment hospitals reported higher postacute care provider utilization capacity. Experience with multiple payment models may prompt hospitals to make different investments or adopt different strategies than hospitals with experience in a single model.

Ten-Year Evaluation of the Population-Based Integrated Health Care System "Gesundes Kinzigtal"

BACKGROUND

The population-based integrated health care system called "Gesundes Kinzigtal" (Integrierte Versorgung Gesundes Kinzigtal, IVGK) was initiated more than 10 years ago in the Kinzig River Valley region, which is located in the Black Forest in the German state of Baden-Württemberg. IVGK is intended to optimize health care while maximizing cost-effectiveness. It consists of programs for promoting health and for enabling cooperation among service providers, as well as of a shared-savings contract that has enabled resources to be saved every year. The goal of the present study was to investigate trends in the quality of care provided by IVGK over the past ten years in comparison to conventional care.

METHODS

This is a non-randomized observational study with a control-group design (Kinzig River Valley versus 13 structurally comparable control regions), employing data collected by AOK, a large statutory health-insurance provider in Germany, over the period 2006-2015. Quality assessment was conducted with the aid of a set of indicators, developed by the authors, that was based exclusively on claims data. The statistical analysis of the trends in these indicators over time was conducted with preset criteria for the relevance of any observed changes, as well as preset mechanisms of controlling for confounding factors.

RESULTS

For 88 of the 101 evaluable indicators, no relevant difference was seen between the trend over time in the region of the intervention and the average trend in the control regions. Relevant differences in favor of the IVGK were observed for six indicators, and negatively divergent trends compared to the controls were observed for seven indicators. In the main summarizing statistical analysis, no positive or negative difference was found between the Kinzig River Valley and the other regions with respect to trends in the health-care indicators over time.

CONCLUSION

An evaluation based on 101 indicators derived from health-insurance data did not reveal any improvement of the quality of care by IVGK and the totality of the programs that were implemented under it. However, under the conditions of the shared-savings contract, no relevant diminution in the quality of care was observed over a period of 10 years either, compared with structurally similar control regions without an integrated care model.

Disparities in Preventable Hospitalization Among Patients With Alzheimer Diseases

INTRODUCTION

System-level care coordination strategies can be the most effective to promote continuity of care among people with Alzheimer's disease; however, the evidence is lacking. The objective of this study is to determine whether accountable care organizations are associated with lower rates of potentially preventable hospitalizations for people with Alzheimer's disease and whether hospital accountable care organization affiliation is associated with reduced racial and ethnic disparities in preventable hospitalizations among patients with Alzheimer's disease.

METHODS

This study employed a cross-sectional study design and used 2015 Healthcare Cost and Utilization Project inpatient claims data from 11 states and the 2015 American Hospital Association Annual Survey. Logistic regression and the Blinder-Oaxaca decomposition method were used.

RESULTS

African American patients with Alzheimer's disease were less likely to be hospitalized at accountable care organization‒affiliated hospitals than White patients. Among patients with Alzheimer's disease who were hospitalized, hospital accountable care organization affiliation was associated with lower odds of potentially preventable hospitalizations (OR=0.86, p=0.02; OR=0.66, p<0.001 with propensity score matching) after controlling for patient characteristics, hospital characteristics, and state indicators. Hospital accountable care organization affiliation explained 3.01% (p<0.01) of the disparity in potentially preventable hospitalizations between White and African American patients but could not explain disparities between White and Latinx patients.

CONCLUSIONS

Evidence suggests that accountable care organizations may be able to improve care coordination for people with Alzheimer's disease and to reduce disparities between Whites and African Americans. Further research is needed to determine whether this benefit can be attributed to accountable care organization formation or whether providers that participate in accountable care organizations tend to provide higher-quality care.

A Systematic Review of Primary Care and Payment Models on Emergency Department Use in Patients Classified as High Need, High Cost

INTRODUCTION

Reducing costly and harmful ED use by patients classified as high need, high cost is a priority across health care systems. The purpose of this systematic review was to evaluate the impact of various primary care and payment models on ED use and overall costs in patients classified as high need, high cost.

METHODS

Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a search was performed from January 2000 to March 2020 in 3 databases. Two reviewers independently appraised articles for quality. Studies were eligible if they evaluated models implemented in the primary care setting and in patients classified as high need, high cost in the United States. Outcomes included all-cause and preventable ED use and overall health care costs.

RESULTS

In the 21 articles included, 4 models were evaluated: care coordination (n = 8), care management (n = 7), intensive primary care (n = 4), and alternative payment models (n = 2). Statistically significant reductions in all-cause ED use were reported in 10 studies through care coordination, alternative payment models, and intensive primary care. Significant reductions in overall costs were reported in 5 studies, and 1 reported a significant increase. Care management and care coordination models had mixed effects on ED use and overall costs.

DISCUSSION

Studies that significantly reduced ED use had shared features, including frequent follow-up, multidisciplinary team-based care, enhanced access, and care coordination. Identifying primary care models that effectively enhance access to care and improve ongoing chronic disease management is imperative to reduce costly and harmful ED use in patients classified as high need, high cost.

Pandemic Pause: Systematic Review of Cost Variables for Ambulatory Care Organizations Participating in Accountable Care Organizations

Ambulatory health care provider organizations participating in Accountable Care Organizations (ACOs) organizations assume costs beyond typical practice operations that are directly associated with value-based care initiatives. Identifying these variables that influence such costs are essential to an organization’s financial viability. To enable the U.S. healthcare system to respond to the COVID-19 pandemic CMS issued blanket waivers that permit enhanced flexibility, extension, and other emergency declaration changes to ACO reporting requirements through the unforeseen future. This relaxation and even pausing of reporting requirements encouraged the researchers to conduct a systematic review and identify variables that have influenced costs incurred by ambulatory care organizations participating in ACOs prior to the emergency declaration. The research findings identified ACO-ambulatory care variables (enhanced patient care management, health information technology improvements, and organizational ownership/reimbursement models) that helped to reduce costs to the ambulatory care organization. Additional variables (social determinants of health/environmental conditions, lack of integration/standardization, and misalignment of financial incentives) were also identified in the literature as having influenced costs for ambulatory care organizations while participating in an ACO initiative with CMS. Findings can assist ambulatory care organizations to focus on new and optimized strategies as they begin to prepare for the post-pandemic resumption of ACO quality reporting requirements once the emergency declaration is eventually lifted.

The association of continuity of care and risk of mortality in breast cancer patients with cardiometabolic comorbidities

OBJECTIVE

The association of continuity of care (COC) among providers and mortality risk for breast cancer patients with comorbidities is not sufficiently studied.

DESIGN

A retrospective cohort study using the 2006-2014 Surveillance, Epidemiology and End Results (SEER)-Medicare data.

PARTICIPANTS

Newly diagnosed female breast cancer patients (n = 57,578) with comorbidities (hypertension, hyperlipidemia, and/or diabetes).

METHODS

All-cause mortality was assessed annually for up to 5 years. COC was estimated using the Bice-Boxerman index, which included: 1) specialty COC capturing continuity of visits to the same provider type (Primary Care Physicians, Oncologists, and Other specialists) and 2) individual COC capturing continuous care to the same provider regardless of provider specialty. Cox proportional hazards models estimated the hazard ratio (HR) of all-cause mortality across quartile of the COC index.

RESULTS

Mortality was positively associated with advanced tumor stages and number of comorbidities (p < 0.05). Patients with high specialty COC (4th vs. 1st quartile, HR 1.34, 95%CI 1.29-1.40) had higher risks of mortality compared with those with low specialty COC. However, patients with high individual COC (4th vs. 1st quartile, HR 0.53, 95%CI 0.51-0.54) had lower risks of mortality compared to those with low individual COC.

CONCLUSION

Receiving care from fewer providers is associated with lower mortality and from fewer types of provider is associated with higher mortality. The results might be confounded by uncontrolled factors and provoke the need for alternative patient care models that recognize the balance between appropriate subspecialties and minimizing the fragmentation of care within and across subspecialties.

Use of Latent Class Analysis and k-Means Clustering to Identify Complex Patient Profiles

IMPORTANCE

Medically complex patients are a heterogeneous group that contribute to a substantial proportion of health care costs. Coordinated efforts to improve care and reduce costs for this patient population have had limited success to date.

OBJECTIVE

To define distinct patient clinical profiles among the most medically complex patients through clinical interpretation of analytically derived patient clusters.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study analyzed the most medically complex patients within Kaiser Permanente Northern California, a large integrated health care delivery system, based on comorbidity score, prior emergency department admissions, and predicted likelihood of hospitalization, from July 18, 2018, to July 15, 2019. From a starting point of over 5000 clinical variables, we used both clinical judgment and analytic methods to reduce to the 97 most informative covariates. Patients were then grouped using 2 methods (latent class analysis, generalized low-rank models, with k-means clustering). Results were interpreted by a panel of clinical stakeholders to define clinically meaningful patient profiles.

MAIN OUTCOMES AND MEASURES

Complex patient profiles, 1-year health care utilization, and mortality outcomes by profile.

RESULTS

The analysis included 104 869 individuals representing 3.3% of the adult population (mean [SD] age, 70.7 [14.5] years; 52.4% women; 39% non-White race/ethnicity). Latent class analysis resulted in a 7-class solution. Stakeholders defined the following complex patient profiles (prevalence): high acuity (9.4%), older patients with cardiovascular complications (15.9%), frail elderly (12.5%), pain management (12.3%), psychiatric illness (12.0%), cancer treatment (7.6%), and less engaged (27%). Patients in these groups had significantly different 1-year mortality rates (ranging from 3.0% for psychiatric illness profile to 23.4% for frail elderly profile; risk ratio, 7.9 [95% CI, 7.1-8.8], P < .001). Repeating the analysis using k-means clustering resulted in qualitatively similar groupings. Each clinical profile suggested a distinct collaborative care strategy to optimize management.

CONCLUSIONS AND RELEVANCE

The findings suggest that highly medically complex patient populations may be categorized into distinct patient profiles that are amenable to varying strategies for resource allocation and coordinated care interventions.

From Rural Germany, Integrated Care Grows Into A Global Model

Fifteen years after a precursor to the ACO formed in the Black Forest region, a value-based approach to health care gains traction.

Nurse Practitioner Involvement in Medicare Accountable Care Organizations: Association With Quality of Care

The objective was to examine trend and care quality outcomes associated with nurse practitioner (NP) involvement in Accountable Care Organizations (ACOs) via a cross-sectional study of 521 Medicare Shared Savings Program ACOs during 2014 to 2016. Data include ACO provider/beneficiary files, Medicare claims, and ACO performance data with a focus on Medicare beneficiaries with diabetes, chronic obstructive pulmonary disease, or heart failure. ACO care quality measures were stratified by NP involvement and adjusted for patient, provider, and ACO factors. NP involvement was highest in larger ACOs, states that allow NPs full scope of practice, and rural areas. Greater involvement was associated with fewer readmissions and higher scores on measures of preventive care but not chronic disease and medication management. Greater NP involvement in ACOs was associated with improvement in some care quality measures. With NPs' increasing involvement in ACOs, more research is needed to understand the NP role in processes and outcomes of care.

Accountable Care Organizations and Preventable Hospitalizations Among Patients With Depression

INTRODUCTION

Accountable care organizations have been successful in improving quality of care, but little is known about who is benefiting from accountable care organizations and through what mechanism. This study examined variation of potentially preventable hospitalizations for chronic conditions with coexisting depression in adults by hospital accountable care organization affiliation and care coordination strategies by race/ethnicity.

METHODS

Data files of 11 states from 2015 State Inpatient Databases were used to identify potentially preventable hospitalizations for chronic conditions with coexisting depression by race/ethnicity; the 2015 American Hospital Association's Annual Survey was used to identify hospital accountable care organization affiliation; and American Hospital Association's Survey of Care Systems and Payment (collected from January to August 2016) was used to identify hospital Accountable care organizations affiliation and hospital-based care coordination strategies, such as telephonic outreach, and chronic care management. In 2019, multiple logistic regressions was used to test the probability of potentially preventable hospitalization by accountable care organization affiliation and race/ethnicity. The test was repeated on a subsample analysis of accountable care organization-affiliated hospitals by care coordination strategy.

RESULTS

Preventable hospitalizations were significantly lower among accountable care organization-affiliated hospitals than accountable care organization-unaffiliated hospitals. Lower preventable hospitalization rates were observed among white, African American, Native American, and Hispanic patients. Effective care coordination strategies varied by patients' race. Results also showed variation of the adoption of specific care coordination strategies among accountable care organization-affiliated hospitals. Analysis further indicated effective care coordination strategies varied by patients' race.

CONCLUSIONS

Accountable care organizations and specifically designed care coordination strategies can potentially improve preventable hospitalization rates and racial disparities among patients with depression. Findings support the integration of mental and physical health services and provide insights for Centers for Medicare and Medicaid Services risk adjustment efforts across race/ethnicity and socioeconomic status.
