ACO-Affiliated Hospitals Reduced Rehospitalizations From Skilled Nursing Facilities Faster Than Other Hospitals

The First Decade of ACO Model Evaluations in the Medicare Program: A Systematic Review

Health care providers participating in five accountable care organization (ACO) models designed, implemented, and evaluated by the Innovation Center at the Centers for Medicare & Medicaid Services have cared for almost six million fee-for-service Medicare patients over the past decade. This systematic review summarizes the features and performance of these ACO models, capturing five major themes arising from their evaluation reports: spending performance by ACO organization type; the role of management companies in ACO structure and performance; financial risk and ACO participation; clinician incentives, waivers, and payment mechanisms; and patient engagement with ACOs. In difference-in-differences analyses, these 214 ACOs lowered spending by an estimated $2.8 billion, or $316.9 million after accounting for shared savings payouts derived from benchmarks, with no evident decrements in quality of care. ACOs' challenge in ongoing and future ACO models is to apply their accrued experience to reduce spending and improve quality within a fee-for-service payment system.

Do Medicare Beneficiaries Under Accountable Care or Medicare Advantage Use Lower Quality Nursing Homes?

BACKGROUND

With the growing number of Medicare beneficiaries attributed to Accountable Care Organizations (ACO) or enrolled in Medicare Advantage (MA) and their financial incentives to lower the cost of the cared patients, it is essential to understand how these alternative payment models affect post-acute outcomes among beneficiaries, with or without dementia diagnoses. In this study, we examined the quality of skilled nursing facilities (SNFs) that beneficiaries entered after hospital discharge under different payment models.

STUDY PARTICIPANTS

Medicare beneficiaries who were discharged from hospitals and admitted to SNFs between 2013 and 2018.

KEY MEASURES

The exposure variable was a payment indicator, including ACO, MA, or non-ACO traditional Medicare (TM) fee-for-service. The dependent variable was high overall quality SNF, defined as with at least 4-star rating in the CMS Nursing Home Care Compare.

ANALYTIC PLAN

We examined the payer distribution by dementia diagnosis using ZIP Code Tabulation Areas (ZCTAs) fixed effects and adjusted for age, gender, and race. We also estimated the probabilities of entering high-quality SNF as a function of payer status and dementia diagnosis each year using hospital and ZCTA fixed effects and accounting for beneficiary-level covariates.

RESULTS

Among SNF admissions from 2013 to 2018, the share of ACO-attributed beneficiaries increased from 7.6% to 20.2%, MA enrollees increased from 25.2% to 32.8%, and non-ACO-attributed TM enrollees decreased from 67.2% to 47.3%. Consistently, ACO-attributed beneficiaries were the most likely, while MA enrollees were the least likely to enter high-quality SNFs, regardless of dementia diagnosis.

CONCLUSIONS

Our findings highlight significant differences in access to high-quality SNFs across Medicare payment models, with ACO-attributed beneficiaries consistently experiencing better access than their MA or traditional Medicare counterparts, regardless of dementia diagnosis. These results underscore the need for further investigation into how payment models influence care quality and access, particularly for vulnerable populations.

Association between hospital participation in Medicare Shared Savings Program and hospital use of robotic surgical approach

BACKGROUND

In 2012, Medicare introduced Shared Savings Program (MSSP) accountable care organizations (ACO) model to improve the value of health care services as a part of the national comprehensive Accountable Care Act. While the effect of the MSSP on primary care has been extensively analyzed, little is known about the effect of the MSSP on cost and quality of surgical care, in particular the use of high-cost robotic surgical modalities. Hospitals routinely market robotic procedures as an indicator of high quality, despite limited evidence of their clinical value. This study examines the relationship between hospital participation in the MSSP and use of robotic surgery.

METHODS

We conducted a retrospective analysis using 2016-2019 publicly available data on hospital MSSP participation and use of robotic-assisted procedures in New York State. Using bivariate and multivariate approaches, we identified hospital characteristics associated with the use of robotic technique and hospital quality.

RESULTS

Of the 157 general hospitals in NYS, 83 (53%) offered robotic surgery and 73 (47%) participated in the MSSP. MSSP-affiliated hospitals were more selective in the type of robotic procedures than non-MSSP hospitals, favoring procedures with stronger evidence-base such as prostatectomies. Hospitals that performed robotic surgery selectively had significantly lower spending per patient (p = 0.04). Higher volume of robotic procedures correlated with higher hospital ranking.

CONCLUSIONS

MSSP participation is associated with more selective use of robotic procedures and lower hospital spending. More research is needed to understand the relationship between hospital investments in quality improvement, use of robotic surgery and hospital performance rankings.

Skilled Nursing and Home Health Policy: A Primer for the Hospital Clinician

This paper addresses the increasing challenges faced by hospital clinicians in coordinating and recommending postacute care for patients, focusing on issues related to access to the most common postacute services: skilled nursing facilities (SNFs) and home health agencies (HHAs). In coordinating discharges, hospital clinicians have minimal information on care delivery in these settings. This knowledge gap is exacerbated by the disrupted continuum of patient care between acute care hospitals, SNFs, and HHAs. To address these challenges, hospital clinicians must understand how recent federal policies have impacted SNF and HHA care provision. The paper provides an overview of recent Centers for Medicare and Medicaid Services (CMS) policies and programs affecting SNFs and HHAs, including: (1) fee-for-service reimbursement reform (ie, Patient Driven Payment Model [PDPM] and the Patient Driven Groupings Model [PDGM]); (2) bundled payment programs; (3) accountable care organizations; (4) Medicare Advantage plans. Overall, this paper aims to help hospital clinicians stay informed about the evolving landscape of postacute care delivery by providing relevant information on how recent policy changes have impacted patient care.

How to facilitate the introduction of value-based payment models?

Value-based payment (VBP) models are designed and implemented to improve outcomes at the same or lower costs. Their adoption requires significant changes in the way healthcare organisations and insurance companies operate. Usually, before VBP models are widely implemented, pilot projects are conducted. Payers need to have a comprehensive set of requirements to enter into agreements with healthcare organisations on these pilots. In this short communication, we outline key elements reported in the literature, inside and outside healthcare organisations, as well as within the contract, that need to be considered in a pilot VBP model. Discussions regarding the introduction of VBP models may be strongly affected by external contextual factors, including regulations, which are outside the control of healthcare organisations. It requires collaboration between organisations, including primary care organisations and hospitals, while within organisations, it frequently requires creating multidisciplinary teams. The focus is on ensuring transparency, collaboration, and shared decision-making, realised by standardising communication processes and regular meetings. Additionally, effective leadership is needed, in which leaders set goals and priorities, as well as manage change. In the contractual agreements between payers and healthcare organisations, outcome measures need to be adequately defined and measured, including individual patient outcomes and composite scores, as well as absolute and relative performance measures. These measures should be tested periodically and catered to the organisations adopting the model. Also, incentives should have adequate size and frequency and be intrinsic and extrinsic. The consideration of these sets of key elements by the payers is essential when implementing VBP model pilot projects.

The Impact of Nurse Practitioner Care and Accountable Care Organization Assignment on Skilled Nursing Services and Hospital Readmissions

BACKGROUND

Accountable care organizations (ACOs) and the employment of nurse practitioners (NP) in place of physicians are strategies that aim to reduce the cost and improve the quality of routine care delivered in skilled nursing facilities (SNF). The recent expansion of ACOs and nurse practitioners into SNF settings in the United States may be associated with improved health outcomes for patients.

OBJECTIVES

To determine the relationship between ACO attribution and NP care delivery during SNF visits and the relationship between NP care delivery during SNF visits and unplanned hospital readmissions.

METHODS

We obtained a sample of 527,329 fee-for-service Medicare beneficiaries with 1 or more SNF stays between 2012 and 2017. We used logistic regression to measure the association between patient ACO attribution and evaluation and management care delivered by NPs in addition to the relationship between evaluation and management services delivered by NPs and hospital readmissions.

RESULTS

ACO beneficiaries were 1.26% points more likely to receive 1 or more E&M services delivered by an NP during their SNF visits [Marginal Effect (ME): 0.0126; 95% CI: (0.009, 0.0160)]. ACO-attributed beneficiaries receiving most of their E&M services from NPs during their SNF visits were at a lower risk of readmission than ACO-attributed beneficiaries receiving no NP E&M care (5.9% vs. 7.1%; P <0.001).

CONCLUSIONS

Greater participation by the NPs in care delivery in SNFs was associated with a reduced risk of patient readmission to hospitals. ACOs attributed beneficiaries were more likely to obtain the benefits of greater nurse practitioner involvement in their care.

The Impact of the Swedish Care Coordination Act on Hospital Readmission and Length-of-Stay among Multi-Morbid Elderly Patients: A Controlled Interrupted Time Series Analysis

Coordinating follow-up care after discharge from hospital is critical to ensuring good outcomes for patients, but is difficult when multiple care providers are involved. In 2018, Sweden adopted the Care Coordination Act, which modified economic incentives to reduce discharge delays and mandated a discharge planning process for patients requiring post-discharge social- or primary care services. This study evaluates the impact of this reform on hospital length-of-stay and unplanned readmissions among multi-morbid elderly patients. Interrupted time series analysis of all in-patient care episodes involving multi-morbid elderly patients in Sweden from 2015 - 2019 (n = 2 386 039) was performed. Secondary analyses using case-mix adjustment and controlled interrupted time series analysis were employed to assess for bias. Average length of stay decreased during the post-reform period, corresponding to 248 521 saved care days. Unplanned readmissions meanwhile increased, corresponding to 7 572 excess unplanned readmissions. While reductions in length-of-stay were concentrated among patients targeted by the reform, increases in readmission rates were similar in patients not targeted by the reform, indicating potential confounding. The reform thus appears to have achieved its goal of decreasing in-patient length of stay, but a robust effect on readmissions, outpatient visits, or mortality was not found. This may be due to lackluster implementation or an ineffective mandated intervention.

The impact of Medicare shared savings program participation on hospital financial performance: An event-study analysis

OBJECTIVE

To evaluate the impact of hospitals' participation in the Medicare Shared Savings Program (MSSP) on their financial performance.

DATA SOURCES

Centers for Medicare & Medicaid Services Hospital Cost Reports and MSSP Accountable Care Organizations (ACO) Provider-Level Research Identifiable File from 2011 to 2018.

STUDY DESIGN

We used an event-study design to estimate the temporal effects of MSSP participation on hospital financial outcomes and compared within-hospital changes over time between MSSP and non-MSSP hospitals while controlling for hospital and year fixed effects and organizational and service-area characteristics. The following financial outcomes were evaluated: outpatient revenue, inpatient revenue, net patient revenue, Medicare revenue, operating margin, inpatient revenue share, Medicare revenue share, and allowance and discount rate.

DATA COLLECTION/EXTRACTION METHODS

Secondary data linked at the hospital level.

PRINCIPAL FINDINGS

Controlling for trends in non-MSSP hospitals, MSSP participation was associated with differential increases in net patient revenue by $3.28 million (p < 0.001), $3.20 million (p < 0.01), and $4.20 million (p < 0.01) in the second, third, and fourth year and beyond after joining MSSP, respectively. Medicare revenue differentially increased by $1.50 million (p < 0.05), $2.24 million (p < 0.05), and $4.47 million (p < 0.05) in the first, second, and fourth year and beyond. Inpatient revenue share differentially increased by 0.29% (p < 0.05) in the second year and 0.44% (p < 0.05) in the fourth year and beyond. Medicare revenue share differentially increased by 0.17% (p < 0.01), 0.25% (p < 0.01), 0.32% (p < 0.01), and 0.41% (p < 0.01) in consecutive years following MSSP participation. MSSP participation was associated with 0.33% (p < 0.05) and 0.39% (p < 0.05) differential reduction in allowance and discount rate in the second and third years.

CONCLUSIONS

MSSP participation was associated with differential increases in net patient revenue, Medicare revenue, inpatient revenue share, and Medicare revenue share, and a differential reduction in allowance and discount rate.

Ninety-Day Risk-Standardized Home Time as a Performance Metric for Cardiac Surgery Hospitals in the United States

BACKGROUND

Assessing hospital performance for cardiac surgery necessitates consistent and valid care quality metrics. The association of hospital-level risk-standardized home time for cardiac surgeries with other performance metrics such as mortality rate, readmission rate, and annual surgical volume has not been evaluated previously.

METHODS

The study included Medicare beneficiaries who underwent isolated or concomitant coronary artery bypass graft, aortic valve, or mitral valve surgery from January 1, 2013, to October 1, 2019. Hospital-level performance metrics of annual surgical volume, 90-day risk-standardized mortality rate, 90-day risk-standardized readmission rate, and 90-day risk-standardized home time were estimated starting from the day of surgery using generalized linear mixed models with a random intercept for the hospital. Correlations between the performance metrics were assessed using the Pearson correlation coefficient. Patient-level clinical outcomes were also compared across hospital quartiles by 90-day risk-standardized home time. Last, the temporal stability of performance metrics for each hospital during the study years was also assessed.

RESULTS

Overall, 919 698 patients (age 74.2±5.8 years, 32% women) were included from 1179 hospitals. Median 90-day risk-standardized home time was 71.2 days (25th-75th percentile, 66.5-75.6), 90-day risk-standardized readmission rate was 26.0% (19.5%-35.7%), and 90-day risk-standardized mortality rate was 6.0% (4.0%-8.8%). Across 90-day home time quartiles, a graded decline was observed in the rates of in-hospital, 90-day, and 1-year mortality, and 90-day and 1-year readmission. Ninety-day home time had a significant positive correlation with annual surgical volume (r=0.31; P<0.001) and inverse correlation with 90-day risk-standardized readmission rate (r=-0.40; P <0.001) and 90-day risk-standardized mortality rate (r=-0.60; P <0.001). Use of 90-day home time as a performance metric resulted in a meaningful reclassification in performance ranking of 22.8% hospitals compared with annual surgical volume, 11.6% compared with 90-day risk-standardized mortality rate, and 19.9% compared with 90-day risk-standardized readmission rate. Across the 7 years of the study period, 90-day home time demonstrated the most temporal stability of the hospital performance metrics.

CONCLUSIONS

Ninety-day risk-standardized home time is a feasible, comprehensive, patient-centered metric to assess hospital-level performance in cardiac surgery with greater temporal stability than mortality and readmission measures.

The Effect of Network-Level Payment Models on Care Network Performance: A Scoping Review of the Empirical Literature

Introduction

Traditional payment models reward volume rather than value. Moving away from reimbursing separate providers to network-level reimbursement is assumed to support structural changes in health care organizations that are necessary to improve patient care. This scoping review evaluates the performance of care networks that have adopted network-level payment models.

Methods

A scoping review of the empirical literature was conducted according to the five-step York framework. We identified indicators of performance, categorized them in four categories (quality, utilization, spending and other consequences) and scored whether performance increased, decreased, or remained stable due to the payment model.

Results

The 76 included studies investigated network-level capitation, disease-based bundled payments, pay-for-performance and blended global payments. The majority of studies stem from the USA. Studies generally concluded that performance in terms of quality and utilization increased or remained stable. Most payment models were associated with improved spending performance. Overall, our review shows that network-level payment models are moderately successful in improving network performance.

Discussion/conclusion

As health care networks are increasingly common, it seems fruitful to continue experimenting with reimbursement models for health care networks. It is also important to broaden the scope to not only scrutinize outcomes, but also the contexts and mechanisms that lead to certain 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.

Variability in skilled nursing facility screening and admission processes: Implications for value-based purchasing

BACKGROUND

Hospitalized older adults are increasingly admitted to skilled nursing facilities (SNFs) for posthospital care. However, little is known about how SNFs screen and evaluate potential new admissions. In an era of increasing emphasis on postacute care outcomes, these processes may represent an important target for interventions to improve the value of SNF care.

PURPOSE

The aim of this study was to understand (a) how SNF clinicians evaluate hospitalized older adults and make decisions to admit patients to an SNF and (b) the limitations and benefits of current practices in the context of value-based payment reforms.

METHODS

We used semistructured interviews to understand the perspective of 18 clinicians at three unique SNFs-including physicians, nurses, therapists, and liaisons. All transcripts were analyzed using a general inductive theme-based approach.

RESULTS

We found that the screening and admission processes varied by SNF and that variability was influenced by three key external pressures: (a) inconsistent and inadequate transfer of medical documentation, (b) lack of understanding among hospital staff of SNF processes and capabilities, and (c) hospital payment models that encouraged hospitals to discharge patients rapidly. Responses to these pressures varied across SNFs. For example, screening and evaluation processes to respond to these pressures included gaining access to electronic medical records, providing inpatient physician consultations prior to SNF acceptance, and turning away more complex patients for those perceived to be more straightforward rehabilitation patients.

CONCLUSIONS

We found facility behavior was driven by internal and external factors with implications for equitable access to care in the era of value-based purchasing.

PRACTICE IMPLICATIONS

SNFs can most effectively respond to these pressures by increasing their agency within hospital-SNF relationships and prioritizing more careful patient screening to match patient needs and facility capabilities.

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.

The Effect of Medicare Shared Savings Program on Readmissions and Variations by Race/Ethnicity and Payer Status (December 9, 2020)

OBJECTIVE

Accountable care organizations in the Medicare Shared Savings Program (MSSP) in the United States attempt to reduce cost and improve quality for their patients by improving care coordination across care settings. We examined the impact of hospital participation in the MSSP on 30-day readmissions for several groups of Medicare inpatients, and by race/ethnicity and payer status.

MAIN DATA SOURCE

A 2010-2016 Medicare Provider Analysis and Review files.

RESEARCH DESIGN

With propensity score matched sample of MSSP and non-MSSP-participating hospitals, patient-level linear probability models with difference-in-differences approach were used to compare the changes in readmission rates for Medicare fee-for-service patients initially admitted for ischemic stroke, hip fracture, or total joint arthroplasty in MSSP-participating hospitals with non-MSSP-participating hospitals as well as to compare the changes in disparities in readmission rates over time.

PRINCIPAL FINDINGS

Hospital participation in MSSP was associated with further reduced readmission rate by 1.1 percentage points (95% confidence interval: -0.02 to 0.00, P<0.05) and 1.5 percentage points (95% confidence interval: -0.03 to 0.00, P=0.08) for ischemic stroke and hip fracture cohorts, respectively, compared with non-MSSP-participating hospitals, after the third year of hospital participation in the MSSP. There was no evidence that MSSP had an impact on racial/ethnic disparities, but increased disparity by payer status (dual vs. Medicare-only) was observed. These findings together suggest that MSSP accountable care organizations may take at least 3 years to achieve reduced readmissions and may increase disparities by payer status.

The Effects of Accountable Care Organizations Forming Preferred Skilled Nursing Facility Networks on Market Share, Patient Composition, and Outcomes

BACKGROUND

Through participation in payment reforms such as bundled payment and accountable care organizations (ACOs), hospitals are increasingly financially responsible for health care use and adverse health events occurring after hospital discharge. To improve management and coordination of postdischarge care, ACO hospitals are establishing a closer relationship with skilled nursing facilities (SNFs) through the formation of preferred SNF networks.

RESEARCH DESIGN

We evaluated the effects of preferred SNF network formation on care patterns and outcomes. We included 10 ACOs that established preferred SNF networks between 2014 and 2015 in the sample. We first investigated whether hospitals "steer" patients to preferred SNFs by examining the percentage of patients sent to preferred SNFs within each hospital before and after network formation. We then used a difference-in-difference model with SNF fixed effects to evaluate the changes in patient composition and outcomes of preferred SNF patients from ACO hospitals after network formation relative to patients from other hospitals.

RESULTS

We found that preferred network formation was not associated with higher market share or better outcomes for preferred SNF patients from ACO hospitals. However, we found a small increase in the average number of Elixhauser comorbidities for patients from ACO hospitals after network formation, relative to patients from non-ACO hospitals.

CONCLUSIONS

After preferred SNF network formation, there is some evidence that ACO hospitals sent more complex patients to preferred SNFs, but there was no change in the volume of patients received by these SNFs. Furthermore, preferred network formation was not associated with improvement in patient outcomes.

Evidence based processes to prevent readmissions: more is better, a ten-site observational study

Background

30-day hospital readmissions are an indicator of quality of care; hospitals are financially penalized by Medicare for high rates. Numerous care transition processes reduce readmissions in clinical trials. The objective of this study was to examine the relationship between the number of evidence-based transitional care processes used and the risk standardized readmission rate (RSRR).

Methods

Design: Mixed method, multi-stepped observational study. Data collection occurred 2014–2018 with data analyses completed in 2021. Setting: Ten VA hospitals, chosen for 5-year trend of improving or worsening RSRR prior to study start plus documented efforts to reduce readmissions. Participants: During five-day site visits, three observers conducted semi-structured interviews (n = 314) with staff responsible for care transition processes and observations of care transitions work (n = 105) in inpatient medicine, geriatrics, and primary care. Exposure: Frequency of use of twenty recommended care transition processes, scored 0–3. Sites’ individual process scores and cumulative total scores were tested for correlation with RSRR. Outcome: best fit predicted RSRR for quarter of site visit based on the 21 months surrounding the site visits.

Results

Total scores: Mean 38.3 (range 24–47). No site performed all 20 processes. Two processes (pre-discharge patient education, medication reconciliation prior to discharge) were performed at all facilities. Five processes were performed at most facilities but inconsistently and the other 13 processes were more varied across facilities. Total care transition process score was correlated with RSRR (R² = 0..61, p < 0.007).

Conclusions

Sites making use of more recommended care transition processes had lower RSRR. Given the variability in implementation and barriers noted by clinicians to consistently perform processes, further reduction of readmissions will likely require new strategies to facilitate implementation of these evidence-based processes, should include consideration of how to better incorporate activities into workflow, and may benefit from more consistent use of some of the more underutilized processes including patient inclusion in discharge planning and increased utilization of community supports. Although all facilities had inpatient social workers and/or dedicated case managers working on transitions, many had none or limited true bridging personnel (following the patient from inpatient to home and even providing home visits). More investment in these roles may also be needed.

Value-Based Provider Payment Initiatives Combining Global Payments With Explicit Quality Incentives: A Systematic Review

An essential element in the pursuit of value-based health care is provider payment reform. This article aims to identify and analyze payment initiatives comprising a specific manifestation of value-based payment reform that can be expected to contribute to value in a broad sense: (a) global base payments combined with (b) explicit quality incentives. We conducted a systematic review of the literature, consulting four scientific bibliographic databases, reference lists, the Internet, and experts. We included and compared 18 initiatives described in 111 articles/documents on key design features and impact on value. The initiatives are heterogeneous regarding the operationalization of the two payment components and associated design features. Main commonalities between initiatives are a strong emphasis on primary care, the use of "virtual" spending targets, and the application of risk adjustment and other risk-mitigating measures. Evaluated initiatives generally show promising results in terms of lower spending growth with equal or improved quality.

Medicare Shared Savings Program and readmission rate among patients with ischemic stroke

OBJECTIVE

Hospitals participating in the Medicare Shared Savings Program (MSSP) share with the Centers for Medicare and Medicaid Services (CMS) the savings generated by reduced cost of care. Our aim was to determine whether MSSP is associated with changes in readmissions and mortality for Medicare patients hospitalized with ischemic stroke, and whether MSSP has a different impact on safety net hospitals (SNHs) compared to non-SNHs.

METHODS

This study was based on the CMS Hospital Compare data for risk-standardized 30-day readmission and mortality rates for Medicare patients hospitalized with ischemic strokes between 2010 and 2017. With a propensity score-matched sample, hospital-level difference-in-difference analysis was used to determine whether MSSP was associated with changes in hospital readmission and mortality as well as to examine the impact of MSSP on SNHs compared to non-SNHs.

RESULTS

MSSP-participating hospitals had slightly greater reductions in readmission rates compared to matched nonparticipating hospitals (difference, 0.25 percentage points; 95% confidence interval [CI], -0.42 to -0.08). Mortality rates decreased among all hospitals, but mortality reduction was not significantly different between MSSP-participating hospitals and matched hospitals (difference, 0.06 percentage points; 95% CI, -0.28 to 0.17). Prior to MSSP, readmission rates in SNHs were higher compared to non-SNHs, but MSSP did not have significantly different impact on hospital readmission and mortality rates for SNHs and non-SNHs.

CONCLUSION

MSSP led to slightly fewer readmissions without increases in mortality for Medicare patients hospitalized with ischemic stroke. Similar reductions in readmission rates were observed in SNHs and non-SNHs participating in MSSP, indicating persistent gaps between SNHs and non-SNHs.

Trends In Hospitals And Skilled Nursing Facilities Sharing Medical Providers, 2008-16

Hospitals and skilled nursing facilities (SNFs) face increasing pressure to improve care coordination and reduce unnecessary readmissions. One strategy to accomplish this is to share physicians and advanced practice clinicians, so that the same providers see patients in both settings. Using 2008-16 Medicare claims, we found that as SNFs moved increasingly toward using SNF specialists, there was a steady decline in the number of facilities sharing medical providers and in the proportion of SNF primary care delivered by provider practices with both hospital and SNF clinicians (hospital-SNF practices). In SNF fixed effects analyses, we found that SNFs that increased primary care visits by hospital-SNF practices had slightly fewer readmissions, shorter lengths-of-stay, and increased successful community discharges. These findings suggest that SNFs that share medical providers with hospitals may see some benefit from that linkage, although the magnitude of the benefit may be small.

The Hospital Readmissions Reduction Program's Impact on Readmissions From Skilled Nursing Facilities

EXECUTIVE SUMMARY

Hospital readmissions have long served as an indicator of patient recovery and the effectiveness of care. The present study examines the Hospital Readmissions Reduction Program's (HRRP's) impact on hospital readmissions from skilled nursing facilities (SNFs) and the characteristics of SNFs that were predictive of lower readmission rates. Adjusted 30-day readmission rates among 14,666 SNFs in the United States from 2011 through 2015 were examined using linear regression with generalized estimating equations to determine the relationship of the HRRP mandate to readmission rates from SNFs. Findings indicate a significant downward trend in adjusted 30-day readmission rates over time, decreasing 1.4% from 2011 to 2015. Furthermore, lower readmission rates were associated with SNF characteristics including location in a hospital facility, rural designation, higher registered nurse-to-nurse ratios, and not-for-profit status. We found a substantial decrease in SNF-related readmissions associated with HRRP, which may limit the impact of the Protecting Access to Medicare Act. Policy-makers may consider these systemic and structural differences before drafting future legislation targeting hospital readmission from SNFs. In addition, acute care facility operators who do not have an SNF may consider adding one to their facility and/or consider partnering with SNFs to ensure that high-quality programs in these SNFs are in place to reduce 30-day readmissions to the acute care facilities.

Likelihood of hospital readmission in Medicare Advantage and Fee-For-Service within same hospital

OBJECTIVE

To assess the extent to which all-cause 30-day readmission rate varies by Medicare program within the same hospitals.

STUDY DESIGN

We used conditional logistic regression clustered by hospital and generalized estimating equations to compare the odds of unplanned all-cause 30-day readmission between Medicare Fee-for-Service (FFS) and Medicare Advantage (MA).

DATA COLLECTION

Wisconsin Health Information Organization collects claims data from various payers including private insurance, Medicare, and Medicaid, twice a year.

PRINCIPAL FINDINGS

For 62 of 66 hospitals, hospital-level readmission rates for MA were lower than those for Medicare FFS. The odds of 30-day readmission in MA were 0.92 times lower than Medicare FFS within the same hospital (odds ratio, 0.93; 95 percent confidence interval, 0.89-0.98). The adjusted overall readmission rates of Medicare FFS and MA were 14.9 percent and 11.9 percent, respectively.

CONCLUSION

These findings provide additional evidence of potential variations in readmission risk by payer and support the need for improved monitoring systems in hospitals that incorporate payer-specific data. Further research is needed to delineate specific care delivery factors that contribute to differential readmission risk by payer source.

Assessment of Differences in Inpatient Rehabilitation Services for Length of Stay and Health Outcomes Between US Medicare Advantage and Traditional Medicare Beneficiaries

IMPORTANCE

Enrollment in Medicare Advantage (MA) has been increasing and has reached one-third of total Medicare enrollment. Because of data limitations, direct comparison of inpatient rehabilitation services between MA and traditional Medicare (TM) beneficiaries has been very scarce. Subgroups of elderly individuals admitted to inpatient rehabilitation facilities (IRFs) may experience different care outcomes by insurance types.

OBJECTIVE

To measure the differences in length of stay and health outcomes of inpatient rehabilitation services between TM and MA beneficiaries in the US.

DESIGN, SETTING, AND PARTICIPANTS

This multiyear cross-sectional study used the Uniform Data System for Medical Rehabilitation to assess rehabilitation services received by elderly (aged >65 years) Medicare beneficiaries in IRFs between 2007 and 2016 for stroke, hip fracture, and joint replacement. Generalized linear models were used to assess whether an association existed between Medicare insurance type and IRF care outcomes. Models were adjusted for demographic characteristics, clinical conditions, and facility characteristics. Data were analyzed from September 2018 to August 2019.

EXPOSURES

Medicare insurance plan type, TM or MA.

MAIN OUTCOMES AND MEASURES

Inpatient length of stay in IRFs, functional improvements, and possibility of returning to the community after discharge.

RESULTS

The sample included a total of 1 028 470 patients (634 619 women [61.7%]; mean [SD] age, 78.23 [7.26] years): 473 017 patients admitted for stroke, 323 029 patients admitted for hip fracture, and 232 424 patients admitted for joint replacement. Individuals enrolled in MA plans were younger than TM beneficiaries (mean [SD] age, 76.96 [7.02] vs 77.95 [7.26] years for stroke, 79.92 [6.93] vs 80.85 [6.87] years for hip fracture, and 74.79 [6.58] vs 75.88 [6.80] years for joint replacement) and were more likely to be black (17 086 [25.5%] vs 54 648 [17.9%] beneficiaries) or Hispanic (14 496 [28.5%] vs 24 377 [8.3%] beneficiaries). The MA beneficiaries accounted for 21.8% (103 204 of 473 017) of admissions for stroke, 11.5% (37 160 of 323 029) of admissions for hip fracture, and 11.8% (27 314 of 232 424) of admissions for joint replacement. The MA beneficiaries had shorter mean lengths of stay than did TM beneficiaries for both stroke (0.11 day; 95% CI, -0.15 to -0.07 day; 1.15% shorter) and hip fracture (0.17 day; 95% CI, -0.21 to -0.13 day; 0.85% shorter). The MA beneficiaries also had higher possibilities of returning to the community than did TM beneficiaries, by 3.0% (95% CI, 2.6%-3.4%) for stroke and 5.0% (95% CI, 4.4%-5.6%) for hip fracture. The shorter length of stay and better ultimate outcomes were achieved without substantially compromising the intermediate functional improvements. Facility type (freestanding vs within an acute care hospital) and patient alternative payment sources other than Medicare (none vs other) partially explained the differences between insurance types.

CONCLUSIONS AND RELEVANCE

This study suggests that MA enrollees experience shorter length of stay and better outcomes for postacute care than do TM beneficiaries in IRFs. The magnitude of the differences depends on treatment deferability, patient sociodemographic subgroups, and facility characteristics.

The Medicare Shared Savings Program and Outcomes for Ischemic Stroke Patients: a Retrospective Cohort Study

BACKGROUND

Post-stroke care delivery may be affected by provider participation in Medicare Shared Savings Program (MSSP) Accountable Care Organizations (ACOs) through systematic changes to discharge planning, care coordination, and transitional care.

OBJECTIVE

To evaluate the association of MSSP with patient outcomes in the year following hospitalization for ischemic stroke.

DESIGN

Retrospective cohort SETTING: Get With The Guidelines (GWTG)-Stroke (2010-2014) PARTICIPANTS: Hospitalizations for mild to moderate incident ischemic stroke were linked with Medicare claims for fee-for-service beneficiaries ≥ 65 years (N = 251,605).

MAIN MEASURES

Outcomes included discharge to home, 30-day all-cause readmission, length of index hospital stay, days in the community (home-time) at 1 year, and 1-year recurrent stroke and mortality. A difference-in-differences design was used to compare outcomes before and after hospital MSSP implementation for patients (1) discharged from hospitals that chose to participate versus not participate in MSSP or (2) assigned to an MSSP ACO versus not or both. Unique estimates for 2013 and 2014 ACOs were generated.

KEY RESULTS

For hospitals joining MSSP in 2013 or 2014, the probability of discharge to home decreased by 2.57 (95% confidence intervals (CI) = - 4.43, - 0.71) percentage points (pp) and 1.84 pp (CI = - 3.31, - 0.37), respectively, among beneficiaries not assigned to an MSSP ACO. Among discharges from hospitals joining MSSP in 2013, beneficiary ACO alignment versus not was associated with increased home discharge, reduced length of stay, and increased home-time. For patients discharged from hospitals joining MSSP in 2014, ACO alignment was not associated with changes in utilization. No association between MSSP and recurrent stroke or mortality was observed.

CONCLUSIONS

Among patients with mild to moderate ischemic stroke, meaningful reductions in acute care utilization were observed only for ACO-aligned beneficiaries who were also discharged from a hospital initiating MSSP in 2013. Only 1 year of data was available for the 2014 MSSP cohort, and these early results suggest further study is warranted.

Changes in Use of Postacute Care Associated With Accountable Care Organizations in Hip Fracture, Stroke, and Pneumonia Hospitalized Cohorts

OBJECTIVE

To examine changes in more and less discretionary condition-specific postacute care use (skilled nursing, inpatient rehabilitation, home health) associated with Medicare accountable care organization (ACO) implementation.

DATA SOURCES

2009-2014 Medicare fee-for-service claims.

STUDY DESIGN

Difference-in-difference methodology comparing postacute outcomes after hospitalization for hip fracture and stroke (where rehabilitation is fundamental to the episode of care) to pneumonia, (where it is more discretionary) for beneficiaries attributed to ACO and non-ACO providers.

PRINCIPAL FINDINGS

Across all 3 cohorts, in the baseline period ACO patients were more likely to receive Medicare-paid postacute care and had higher episode spending. In hip fracture patients where rehabilitation is standard of care, ACO implementation was associated with 6%-8% increases in probability of admission to a skilled nursing facility or inpatient rehabilitation (compared with home without care), and a slight reduction in readmissions. In a clinical condition where rehabilitation is more discretionary, pneumonia, ACO implementation was not associated with changes in postacute location, but episodic spending decreased 2%-3%. Spending decreases were concentrated in the least complex patients. Across all cohorts, the length of stay in skilled nursing facilities decreased with ACO implementation.

CONCLUSIONS

ACOs decreased spending on postacute care by decreasing use of discretionary services. ACO implementation was associated with reduced length of stay in skilled nursing facilities, while hip fracture patients used institutional postacute settings at higher rates. Among pneumonia patients, we observed decreases in spending, readmission days, and mortality associated with ACO implementation.

Performance in the Medicare Shared Savings Program After Accounting for Nonrandom Exit: An Instrumental Variable Analysis

BACKGROUND

Accountable care organizations (ACOs) in the Medicare Shared Savings Program (MSSP) are associated with modest savings. However, prior research may overstate this effect if high-cost clinicians exit ACOs.

OBJECTIVE

To evaluate the effect of the MSSP on spending and quality while accounting for clinicians' nonrandom exit.

DESIGN

Similar to prior MSSP analyses, this study compared MSSP ACO participants versus control beneficiaries using adjusted longitudinal models that accounted for secular trends, market factors, and beneficiary characteristics. To further account for selection effects, the share of nearby clinicians in the MSSP was used as an instrumental variable. Hip fracture served as a falsification outcome. The authors also tested for compositional changes among MSSP participants.

SETTING

Fee-for-service Medicare, 2008 through 2014.

PATIENTS

A 20% sample (97 204 192 beneficiary-quarters).

MEASUREMENTS

Total spending, 4 quality indicators, and hospitalization for hip fracture.

RESULTS

In adjusted longitudinal models, the MSSP was associated with spending reductions (change, -$118 [95% CI, -$151 to -$85] per beneficiary-quarter) and improvements in all 4 quality indicators. In instrumental variable models, the MSSP was not associated with spending (change, $5 [CI, -$51 to $62] per beneficiary-quarter) or quality. In falsification tests, the MSSP was associated with hip fracture in the adjusted model (-0.24 hospitalizations for hip fracture [CI, -0.32 to -0.16 hospitalizations] per 1000 beneficiary-quarters) but not in the instrumental variable model (0.05 hospitalizations [CI, -0.10 to 0.20 hospitalizations] per 1000 beneficiary-quarters). Compositional changes were driven by high-cost clinicians exiting ACOs: High-cost clinicians (99th percentile) had a 30.4% chance of exiting the MSSP, compared with a 13.8% chance among median-cost clinicians (50th percentile).

LIMITATION

The study used an observational design and administrative data.

CONCLUSION

After adjustment for clinicians' nonrandom exit, the MSSP was not associated with improvements in spending or quality. Selection effects-including exit of high-cost clinicians-may drive estimates of savings in the MSSP.

ACO Affiliated Hospitals Increase Implementation of Care Coordination Strategies

BACKGROUND

Hospitals affiliated with Accountable Care Organizations (ACOs) may have a greater capacity to collaborate with providers across the care continuum to coordinate care, due to formal risk sharing and payment arrangements. However, little is known about the extent to which ACO affiliated hospitals implement care coordination strategies.

OBJECTIVES

To compare the implementation of care coordination strategies between ACO affiliated hospitals (n=269) and unaffiliated hospitals (n=502) and examine whether the implementation of care coordination strategies varies by hospital payment model types.

MEASURES

We constructed a care coordination index (CCI) comprised of 12 indicators that describe evidence-based care coordination strategies. Each indicator was scored on a 5-point Likert scale from 1="not used at all" to 5="used widely" by qualified representatives from each hospital. The CCI aggregates scores from each of the 12 individual indicators to a single summary score for each hospital, with a score of 12 corresponding to the lowest and 60 the highest use of care coordination strategies.

RESEARCH DESIGN

We used state-fixed effects multivariable linear regression models to estimate the relationship between ACO affiliation, payment model type, and the use care coordination strategies.

RESULTS

We found ACO affiliated hospitals reported greater use of care coordination strategies compared to unaffiliated hospitals. Fee-for-service shared savings and partial or global capitation payment models were associated with a greater use of care coordination strategies among ACO affiliated hospitals.

CONCLUSION

Our findings suggest ACO affiliation and multiple payment model types are associated with the increased use of care coordination strategies.

Hospitals Using Bundled Payment Report Reducing Skilled Nursing Facility Use And Improving Care Integration

A goal of Medicare's bundled payment models is to improve quality and control costs after hospital discharge. Little is known about how participating hospitals are focusing their efforts to achieve these objectives, particularly around the use of skilled nursing facilities (SNFs). To understand hospitals' approaches, we conducted semistructured interviews with an executive or administrator in each of twenty-two hospitals and health systems participating in Medicare's Comprehensive Care for Joint Replacement model or its Bundled Payments for Care Improvement initiative for lower extremity joint replacement episodes. We identified two major organizational responses. One principal strategy was to reduce SNF referrals, using risk-stratification tools, patient education, home care supports, and linkages with home health agencies to facilitate discharges to home. Another was to enhance integration with SNFs: fifteen hospitals or health systems in our sample had formed networks of preferred SNFs to exert influence over SNF quality and costs. Common coordination strategies included sharing access to electronic medical records, embedding providers across facilities, hiring dedicated care coordination staff, and creating platforms for data sharing. As hospitals presumably move toward home-based care and more selective SNF referrals, more evidence is needed to understand how these discharge practices affect the quality of care and patient outcomes.

Aggressive Care near the End of Life for Cancer Patients in Medicare Accountable Care Organizations

OBJECTIVES

To compare aggressiveness of end-of-life (EoL) care for older cancer patients attributed to Medicare Shared Savings Programs with that for similar fee for service (FFS) beneficiaries not in an accountable care organization (ACO) and examine whether observed differences in EoL care utilization vary across markets that differ in ACO penetration.

DESIGN

Cross-sectional observational study comparing ACO-attributed beneficiaries with propensity score-matched beneficiaries not attributed to an ACO.

SETTING

A total of 21 hospital referral regions (HRRs) in the United States.

PARTICIPANTS

Medicare FFS beneficiaries with a cancer diagnosis who were 66 years or older and died in 2013-2014.

MEASUREMENTS

Outcome measures were claims-based quality measures of aggressive EoL care: (1) one or more intensive care unit (ICU) admissions in the last month of life, (2) two or more hospitalizations in the last month of life, (3) two or more emergency department visits in the last month of life, (4) chemotherapy 2 weeks or less before death, and (5) no hospice enrollment or hospice enrollment within 3 days of death. Analyses were adjusted for demographic and clinical characteristics of beneficiaries and practice characteristics.

RESULTS

Compared with beneficiaries not in an ACO, ACO-attributed beneficiaries had a higher rate of ICU admission during the last month of life (37.7% vs 34.0%; adjusted difference = +2.8 percentage points; 95% confidence interval (CI) = 1.0-4.6) but fewer repeated hospitalizations (14.5% vs 15.2%; adjusted difference = -1.7 percentage points; CI = -3.1 to -.3). Other measures did not differ for the two groups. Although the ICU admission rates tended to decrease as ACO-penetration rates increased (P < .01), ACO patients had higher rates of ICU admission than non-ACO patients in both medium and high ACO-penetration HRRs.

CONCLUSION

Cancer patients attributed to ACOs had fewer repeated hospitalizations but more ICU admissions in the last month of life than non-ACO patients; they had similar rates of other measures of aggressive care at the EoL. This suggests opportunities for ACOs to improve EoL care for cancer patients. J Am Geriatr Soc 67:961-968, 2019.

Association Between Hospital Participation in Medicare Shared Savings Program Accountable Care Organizations and Readmission Following Major Surgery

OBJECTIVE

To evaluate the effect of Medicare Shared Savings Program accountable care organizations (ACOs) on hospital readmission after common surgical procedures.

SUMMARY BACKGROUND DATA

Hospital readmissions following surgery lead to worse patient outcomes and wasteful spending. ACOs, and their associated hospitals, have strong incentives to reduce readmissions from 2 distinct Centers for Medicare and Medicaid Services policies.

METHODS

We performed a retrospective cohort study using a 20% national Medicare sample to identify beneficiaries undergoing 1 of 7 common surgical procedures-abdominal aortic aneurysm repair, colectomy, cystectomy, prostatectomy, lung resection, total knee arthroplasty, and total hip arthroplasty-between 2010 and 2014. The primary outcome was 30-day risk-adjusted readmission rate. We performed difference-in-differences analyses using multilevel logistic regression models to quantify the effect of hospital ACO affiliation on readmissions following these procedures.

RESULTS

Patients underwent a procedure at one of 2974 hospitals, of which 389 were ACO affiliated. The 30-day risk-adjusted readmission rate decreased from 8.4% (95% CI, 8.1-8.7%) to 7.0% (95% CI, 6.7-7.3%) for ACO affiliated hospitals (P < 0.001) and from 7.9% (95% CI, 7.8-8.0%) to 7.1% (95% CI, 6.9-7.2%) for non-ACO hospitals (P < 0.001). The difference-in-differences of the 2 trends demonstrated an additional 0.52% (95% CI, 0.97-0.078%) absolute reduction in readmissions at ACO hospitals (P = 0.021), which would translate to 4410 hospitalizations avoided.

CONCLUSION

Readmissions following common procedures decreased significantly from 2010 to 2014. Hospital affiliation with Shared Savings ACOs was associated with significant additional reductions in readmissions. This emphasis on readmission reduction is 1 mechanism through which ACOs improve value in a surgical population.

Lost in Transition: a Qualitative Study of Patients Discharged from Hospital to Skilled Nursing Facility

OBJECTIVE

This research aimed to understand the experiences of patients transitioning from hospitals to skilled nursing facilities (SNFs) by eliciting views from patients and hospital and skilled nursing facility staff.

DESIGN

We conducted semi-structured interviews with hospital and skilled nursing facility staff and skilled nursing facility patients and their family members in an attempt to understand transitions between hospital and SNF. These interviews focused on all aspects of the discharge planning and nursing facility placement processes including who is involved, how decisions are made, patients' experiences, hospital-SNF communication, and the presence of programs to improve the transition process.

PARTICIPANTS

Participants were 138 staff in 16 hospitals and 25 SNFs in 8 markets across the country, and 98 newly admitted, previously community-dwelling SNF patients and/or their family members in five of those markets.

APPROACH

Interviews were qualitatively analyzed to identify overarching themes.

KEY RESULTS

Patients reported they felt rushed in making their SNF decisions, did not feel they were appropriately prepared for the hospital-SNF transition or educated about their post-acute needs, and experienced transitions that felt chaotic, with complications they associated with timing and medications. Hospital and SNF staff expressed similar opinions, stating that transitions were rushed, there were problems with the timing of the discharge, with information transfer and medication reconciliation, and that patients were not appropriately prepared for the transition. Staff at some facilities reported programs designed to address these problems, but the efficacy of these programs is unknown.

CONCLUSIONS

Results indicate problematic transitions stemming from insufficient care coordination and failure to appropriately prepare patients and their family members. Previous research suggests that problematic or hurried transitions from hospital to SNF are associated with medication errors and unnecessary rehospitalizations. Interventions to improve transitions from hospital to SNF that include a focus on patients and families are needed.

Local Health Departments' Promotion of Mental Health Care and Reductions in 30-Day All-Cause Readmission Rates in Maryland

BACKGROUND

Individuals affected with mental health conditions, including mood disorders and substance abuse, are at an increased risk of hospital readmission.

OBJECTIVES

The objective of this study is to examine whether local health departments' (LHDs) active roles of promoting mental health are associated with reductions in 30-day all-cause readmission rates, a common quality metric.

METHODS

Using datasets linked from multiple sources, including 2012-2013 State Inpatient Databases for the State of Maryland, the National Association of County and City Health Officials Profiles Survey, the Area Health Resource File, and US Census data, we employed multivariate logistic models to examine whether LHDs' active provision of mental health preventive care, mental health services, and health promotion were associated with the likelihood of having any 30-day all-cause readmission.

RESULTS

Multivariate logistic regressions showed that LHDs' provision of mental health preventive care, mental health services, and health promotion were negatively associated with the likelihoods of having any 30-day readmission for adults 18-64 years old (odds ratios=0.71-0.82, P<0.001), and adults 65 and above (odds ratios=0.61-0.63, P<0.001, preventive care and services, respectively). These estimated associations were more prominent among individuals with mental illness and/or substance use disorders, African Americans, Medicare, and Medicaid enrollees.

CONCLUSIONS

Our results suggest that LHDs in Maryland that engage in mental health prevention, promotion, and coordination activities are associated with benefits for residents and for the health care system at large. Additional research is needed to evaluate LHD activities in other states to determine if these results are generalizable.

Assessment of Between-Hospital Variation in Readmission and Mortality After Cancer Surgical Procedures

Importance

Although current federal quality improvement programs do not include cancer surgery, the Centers for Medicare & Medicaid Services and other payers are considering extending readmission reduction initiatives to include these and other common high-cost episodes.

Objectives

To quantify between-hospital variation in quality-related outcomes and identify hospital characteristics associated with high and low performance.

Design, Setting, and Participants

This retrospective cohort study obtained data through linkage of the California Cancer Registry to hospital discharge claims databases maintained by the California Office of Statewide Health Planning and Development. All 351 acute care hospitals in California at which 1 or more adults underwent curative intent surgery between January 1, 2007, and December 31, 2011, with analyses finalized July 15, 2018, were included. A total of 138 799 adults undergoing surgery for colorectal, breast, lung, prostate, bladder, thyroid, kidney, endometrial, pancreatic, liver, or esophageal cancer within 6 months of diagnosis, with an American Joint Committee on Cancer stage of I to III at diagnosis, were included.

Main Outcomes and Measures

Measures included adjusted odds ratios and variance components from hierarchical mixed-effects logistic regression analyses of in-hospital mortality, 90-day readmission, and 90-day mortality, as well as hospital-specific risk-adjusted rates and risk-adjusted standardized rate ratios for hospitals with a mean annual surgical volume of 10 or more.

Results

Across 138 799 patients at the 351 included hospitals, 8.9% were aged 18 to 44 years and 45.9% were aged 65 years or older, 57.4% were women, and 18.2% were nonwhite. Among these, 1240 patients (0.9%) died during the index admission. Among 137 559 patients discharged alive, 19 670 (14.3%) were readmitted and 1754 (1.3%) died within 90 days. After adjusting for patient case-mix differences, evidence of statistically significant variation in risk across hospitals was identified, as characterized by the variance of the random effects in the mixed model, for all 3 metrics (P < .001). In addition, substantial variation was observed in hospital performance profiles: across 260 hospitals with a mean annual surgical volume of 10 or more, 59 (22.7%) had lower-than-expected rates for all 3 metrics, 105 (40.4%) had higher-than-expected rates for 2 of the 3, and 19 (7.3%) had higher-than-expected rates for all 3 metrics.

Conclusions and Relevance

Accounting for patient case-mix differences, there appears to be substantial between-hospital variation in in-hospital mortality, 90-day readmission, and 90-day mortality after cancer surgical procedures. Recognizing the multifaceted nature of hospital performance through consideration of mortality and readmission simultaneously may help to prioritize strategies for improving surgical outcomes.

Assessing the Quality of Nursing Homes in Managed Care Organizations: Integrating LTSS for Dually Eligible Beneficiaries

Little is known about the quality of nursing homes in managed care organizations (MCOs) networks. This study (1) described decision-making criteria for selecting nursing home networks and (2) compared selected quality indicators of network and nonnetwork nursing homes. The sample was 17 MCOs participating in a California demonstration that provided integrated long-term services and supports to dually eligible enrollees in 2017. The findings showed that the MCOs established a broad network of nursing homes, with only limited attention to using quality criteria. Network nursing homes (602) scored significantly lower on 6 selected quality measures than nonnetwork (117) nursing homes. Low registered nurse and total nurse staffing were strong predictors of network nursing homes controlling for facility characteristics. Managed care organizations should consider greater transparency about the quality of their nursing homes and use specific quality criteria to improve the quality of their networks.

Hospital-Skilled Nursing Facility Collaboration: A Mixed-Methods Approach to Understanding the Effect of Linkage Strategies

OBJECTIVE

To characterize the nature and degree of hospitals' efforts to collaborate with skilled nursing facilities (SNFs) and associated patient outcomes.

DATA SOURCES/STUDY SETTING

Qualitative data were collected through 138 interviews with staff in 16 hospitals and 25 SNFs in eight markets across the United States in 2015. Quantitative data include Medicare claims data for the 290,603 patients discharged from those 16 hospitals between 2008 and 2015.

STUDY DESIGN/DATA COLLECTION

Semi-structured interviews with hospital and SNF staff were coded and used to classify hospitals' collaboration efforts with SNFs into high versus low collaboration hospitals, and risk-adjusted, claims-based hospital readmission rates from SNF were compared.

PRINCIPAL FINDINGS

Hospital collaboration efforts were defined as establishing SNF partners, transition management initiatives, and hospital staff visits to SNFs. High collaboration hospitals were more likely to send patients to SNFs (as opposed to home, home with home health, or other PAC settings), sent a higher share of patients to high quality SNFs, and had fewer hospital readmissions from SNF sooner than did low collaboration hospitals.

CONCLUSIONS

Although collaboration with SNF requires significant administrative and clinical time investment, it is associated with positive patient outcomes.

Accountable Care Organizations and Post-Acute Care: A Focus on Preferred SNF Networks

Due to high magnitude and variation in spending on post-acute care, accountable care organizations (ACOs) are focusing on transforming management of hospital discharge through relationships with preferred skilled nursing facilities (SNFs). Using a mixed-methods design, we examined survey data from 366 respondents to the National Survey of ACOs along with 16 semi-structured interviews with ACOs who performed well on cost and quality measures. Survey data revealed that over half of ACOs had no formal relationship with SNFs; however, the majority of ACO interviewees had formed preferred SNF networks. Common elements of networks included a comprehensive focus on care transitions beginning at hospital admission, embedded ACO staff across settings, solutions to support information sharing, and jointly established care protocols. Misaligned incentives, unclear regulations, and a lack of integrated health records remained challenges, yet preferred networks are beginning to transform the ACO post-acute care landscape.

Challenges and Consequences of Reduced Skilled Nursing Facility Lengths of Stay

OBJECTIVE

To identify the challenges that reductions in length of stay (LOS) pose for skilled nursing facilities (SNFs) and their postacute care (PAC) patients.

DATA SOURCES/SETTING

Seventy interviews with staff in 25 SNFs in eight U.S. cities, LOS data for patients in those SNFs.

STUDY DESIGN

Data were qualitatively analyzed, and key themes were identified. Interview data from SNFs with and without reductions in median risk-adjusted LOS were compared and contrasted.

DATA COLLECTION/EXTRACTION METHODS

We conducted 70 semistructured interviews. LOS data were derived from minimum dataset (MDS) admission records available for all patients in all U.S. SNFs from 2012 to 2014.

PRINCIPAL FINDINGS

Challenges reported regardless of reductions in LOS included frequent and more complicated re-authorization processes, patients becoming responsible for costs, and discharging patients whom staff felt were unsafe at home. Challenges related to reduced LOS included SNFs being pressured to discharge patients within certain time limits. Some SNFs reported instituting programs and processes for following up with patients after discharge. These programs helped alleviate concerns about patients, but they resulted in nonreimbursable costs for facilities.

CONCLUSIONS

The push for shorter LOS has resulted in unexpected challenges and costs for SNFs and possible unintended consequences for PAC patients.

Do Changes in Post-acute Care Use at Hospitals Participating in an Accountable Care Organization Spillover to All Medicare Beneficiaries?

BACKGROUND

While early evidence suggests that Medicare accountable care organizations (ACOs) may reduce post-acute care (PAC) utilization for attributed beneficiaries, whether these effects spill over to all beneficiaries admitted to hospitals participating in ACOs stray is unknown.

OBJECTIVE

The objective of this study was to evaluate whether changes in PAC use and Medicare spending spill over to all beneficiaries admitted to hospitals participating in the Medicare Shared Savings Program (MSSP).

DESIGN

Observational study using a difference-in-differences design comparing changes in PAC utilization and spending among beneficiaries admitted to ACO-participating hospitals before and after the start of the ACO contracts, compared to those admitted to non-ACO hospitals.

SETTING

A total of 233 hospitals participate in MSSP ACOs and 3103 non-ACO hospitals.

PARTICIPANTS

A national sample of 11,683,573 Medicare beneficiaries experiencing 26,503,086 hospital admissions from 2010 to 2013.

EXPOSURE

Admission to a hospital participating in an MSSP ACO.

MAIN MEASURES

The probability of discharge and Medicare payments to inpatient rehabilitation facilities (IRF), skilled nursing facilities (SNF), and home health agencies (HHA).

KEY RESULTS

For beneficiaries admitted to hospitals that joined an ACO, the likelihood of being discharged to PAC did not change after the hospital joined the ACO compared with non-ACO hospitals over the same period (differential change in probability of discharge to any PAC was 0.000 (P = 0.89), SNF was 0.000 (P = 0.73), IRF was 0.000 (P = 0.96), and HHA was 0.001 (P = 0.57)). Payments reduced significantly for PAC overall (- $130.41, P = 0.03), but not for any individual PAC type alone. These results were consistent in samples that were conditional on discharge to any PAC, across conditions with high PAC use nationally, and among ACO-participating hospitals that also had a PAC participant.

CONCLUSIONS

Hospital participation in an ACO did not result in spillovers in PAC utilization or payments to all beneficiaries, even when considering high PAC-use conditions and ACO hospitals that also have an ACO-participating PAC.

Hospitalist Value in an ACO World

The accountable care organization (ACO) concept is advocated as a promising value-based payment model that could successfully realign the current payment system to financially reward improvements in quality and efficiency. Focusing on the care of hospitalized patients and controlling a substantive portion of variable hospital expenses, hospitalists are poised to play an essential role in system-level transformational change to achieve clinical integration. Especially through hospital and health system quality improvement (QI) initiatives, hospitalists can directly impact and share accountability for measures ranging from care coordination to implementation of evidence-based care and the patient and family caregiver experience. Regardless of political terrain, financial constraints in healthcare will foster continued efforts to promote formation of ACOs that aim to deliver coordinated, evidence-based, and patient-centered care. Hospitalists possess the clinical experience of caring for complex patients with multiple comorbidities and the QI skills needed to lead efforts in this new ACO era.

Transformation of the Health Care Industry: Curb Your Enthusiasm?

Policy Points: Policymakers seek to transform the US health care system along two dimensions simultaneously: alternative payment models and new models of provider organization. This transformation is supposed to transfer risk to providers and make them more accountable for health care costs and quality. The transformation in payment and provider organization is neither happening quickly nor shifting risk to providers. The impact on health care cost and quality is also weak or nonexistent. In the longer run, decision makers should be prepared to accept the limits on transformation and carefully consider whether to advocate solutions not yet supported by evidence.

CONTEXT

There is a widespread belief that the US health care system needs to move "from volume to value." This transformation to value (eg, quality divided by cost) is conceptualized as a two-fold movement: (1) from fee-for-service to alternative payment models; and (2) from solo practice and freestanding hospitals to medical homes, accountable care organizations, large hospital systems, and organized clinics like Kaiser Permanente.

METHODS

We evaluate whether this transformation is happening quickly, shifting risk to providers, lowering costs, and improving quality. We draw on recent evidence on provider payment and organization and their effects on cost and quality.

FINDINGS

Data suggest a low prevalence of provider risk payment models and slow movement toward new payment and organizational models. Evidence suggests the impact of both on cost and quality is weak.

CONCLUSIONS

We need to be patient in expecting system improvements from ongoing changes in provider payment and organization. We also may need to look for improvements in other areas of the economy or to accept and accommodate prospects of modest improvements over time.

Impact of Accountable Care Organizations on Utilization, Care, and Outcomes: A Systematic Review

Since 2010, more than 900 accountable care organizations (ACOs) have formed payment contracts with public and private insurers in the United States; however, there has not been a systematic evaluation of the evidence studying impacts of ACOs on care and outcomes across payer types. This review evaluates the quality of evidence regarding the association of public and private ACOs with health service use, processes, and outcomes of care. The 42 articles identified studied ACO contracts with Medicare ( N = 24 articles), Medicaid ( N = 5), commercial ( N = 11), and all payers ( N = 2). The most consistent associations between ACO implementation and outcomes across payer types were reduced inpatient use, reduced emergency department visits, and improved measures of preventive care and chronic disease management. The seven studies evaluating patient experience or clinical outcomes of care showed no evidence that ACOs worsen outcomes of care; however, the impact on patient care and outcomes should continue to be monitored.

Early effect of Medicare Shared Savings Program accountable care organization participation on prostate cancer care

BACKGROUND

Accountable care organizations (ACOs) can improve prostate cancer care by decreasing treatment variations (ie, avoidance of treatment in low-value settings). Herein, the authors performed a study to understand the effect of Medicare Shared Savings Program ACOs on prostate cancer care.

METHODS

Using a 20% Medicare sample, the authors identified men with newly diagnosed prostate cancer from 2010 through 2013. Rates of treatment, potential overtreatment (ie, treatment in men with a ≥75% chance of 10-year mortality from competing risks), and Medicare payments were measured using regression models. The impact of ACO participation was assessed using difference-in-differences analyses.

RESULTS

Before implementation of ACOs, the treatment rate was 71.8% (95% confidence interval [95% CI], 70.2%-73.3%) for ACO-aligned beneficiaries and 72.3% (95% CI, 71.7%-73.0% [P = .51]) for non-ACO-aligned beneficiaries. After implementation, this rate declined to 68.4% (95% CI, 66.1%-70.7% [P = .017]) for ACO-aligned beneficiaries and 69.3% (95% CI, 68.5%-70.1% [P<.001]) for non-ACO-aligned beneficiaries. There was no differential effect noted for ACO participation. The rate of potential overtreatment decreased from 48.2% (95% CI, 43.1%-53.3%) to 40.2% (95% CI, 32.4%-48.0% [P = .087]) for ACO-aligned beneficiaries and increased from 44.3% (95% CI, 42.1%-46.5%) to 47.0% (95% CI, 44.5%-49.5% [P = .11]) for non-ACO-aligned beneficiaries. These changes resulted in a significant relative decrease in overtreatment of 17% for ACO-aligned beneficiaries (difference-in-differences, 10.8%; P = .031). Payments were not found to be differentially affected by ACO alignment.

CONCLUSIONS

The treatment of prostate cancer and annual payments decreased significantly between 2010 and 2013, but ACO participation did not appear to impact these trends. Among men least likely to benefit, Medicare Shared Savings Program ACO alignment was associated with a significant decline in prostate cancer treatment.
