Abstract
Vertical integration of health systems-the common ownership of different aspects of the health care system-continues to occur at increasing rates in the United States. This systematic review synthesizes recent evidence examining the association between two types of vertical integration-hospital-physician (n = 43 studies) and hospital-post-acute care (PAC; n = 10 studies)-and cost, quality, and health services utilization. Hospital-physician integration is associated with higher health care costs, but the effect on quality and health services utilization remains unclear. The effect of hospital-PAC integration on these three outcomes is ambiguous, particularly when focusing on hospital-SNF integration. These findings should raise some concern among policymakers about the trajectory of affordable, high-quality health care in the presence of increasing hospital-physician vertical integration but perhaps not hospital-PAC integration.

Abstract
Amid enthusiasm about accountable care organizations (ACOs) in Medicaid, little is known about the primary care practices engaging in them. We leverage a survey of administrators within a random sample (stratified by ACO) of 225 practices joining Massachusetts Medicaid ACOs (64% response rate; 225 responses). We measure the integration of processes with distinct entities: consulting clinicians, eye specialists for diabetes care, mental/behavioral care providers, and long-term and social services agencies. Using multivariable regression, we examine organizational correlates of integration and assess integration's relationships with care quality improvement, health equity, and satisfaction with the ACO. Integration varied across practices. Clinical integration was positively associated with perceived care quality improvement; social service integration was positively associated with addressing equity; and mental/behavioral and long-term service integration were positively associated with ACO satisfaction (all p < .05). Understanding differences in integration at the practice level is vital for sharpening policy, setting expectations, and supporting improvement in Medicaid ACOs.

The dynamics of integration and integrated care: An exploratory study of physician organizations. Health Care Manage Rev 2023; 48:92-108.

Abstract
BACKGROUND Substantial variation exists in how well health care is integrated, even across similarly structured organizations, yet research about what physician organizations (POs) do that enables or inhibits integrated care is limited. PURPOSE The aim of this study was to explore the dynamics that enable POs to integrate care. METHODOLOGY/APPROACH We ranked a stratified sample of POs according to patient perceptions of integrated care, as measured in a survey. We interviewed professionals, patients, and family members in 10 higher and 3 lower ranked POs about the process of caring for patients with complex conditions. We derived integration-related themes from the interview data and quantified their prevalence. Using a quasi-statistical approach, we explored relationships among themes and their associations with patient perceptions of integrated care. RESULTS From 6,104 coded references, we derived a set of themes representing integration perspectives, integration engagement mechanisms, and integration failures. POs experienced frequent integration failures. Higher ranked POs experienced these failures less often because of a combination of functional, interpersonal, and stakeholder engagement mechanisms, which appear to complement one another. Integration perspectives, including both people-oriented and systems-oriented mindsets, appear to play a role in generating these integration dynamics. CONCLUSION Delivering integrated care depends on a PO's ability to limit integration failures, keeping provider attention focused on patients. Building on the attention-based view, we present a framework suggesting that this ability is a function of both integration perspectives and integration engagement mechanisms. PRACTICE IMPLICATIONS POs interested in delivering more integrated care should employ a variety of complementary integration engagement mechanisms and facilitate these efforts by nurturing both people-oriented and system-oriented mindsets among PO decision-makers.

The Association of Readmission Reduction Activities with Primary Care Practice Readmission Rates. J Gen Intern Med 2022; 37:3005-3012. [PMID: 34258724 PMCID: PMC9485329 DOI: 10.1007/s11606-021-07005-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2021] [Accepted: 06/24/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND A great deal of research has focused on how hospitals influence readmission rates. While hospitals play a vital role in reducing readmissions, a significant portion of the work also falls to primary care practices. Despite this critical role of primary care, little empirical evidence has shown what primary care characteristics or activities are associated with reductions in hospital admissions. OBJECTIVE To examine the relationship between practices' readmission reduction activities and their readmission rates. DESIGN, SETTING, AND PARTICIPANTS A retrospective study of 1,788 practices who responded to the National Survey of Healthcare Organizations and Systems (fielded 2017-2018) and 415,663 hospital admissions for Medicare beneficiaries attributed to those practices from 2016 100% Medicare claims data. We constructed mixed-effects logistic regression models to estimate practice-level readmission rates and a linear regression model to evaluate the association between practices' readmission rates with their number of readmission reduction activities. INTERVENTIONS Standardized composite score, ranging from 0 to 1, representing the number of a practice's readmission reduction capabilities. The composite score was composed of 12 unique capabilities identified in the literature as being significantly associated with lower readmission rates (e.g., presence of care manager, medication reconciliation, shared-decision making, etc.). MAIN OUTCOMES AND MEASURES Practices' readmission rates for attributed Medicare beneficiaries. KEY RESULTS Routinely engaging in more readmission reduction activities was significantly associated (P < .05) with lower readmission rates. On average, practices experienced a 0.05 percentage point decrease in readmission rates for each additional activity. Average risk-standardized readmission rates for practices performing 10 or more of the 12 activities in our composite measure were a full percentage point lower than risk-standardized readmission rates for practices engaging in none of the activities. CONCLUSIONS Primary care practices that engaged in more readmission reduction activities had lower readmission rates. These findings add to the growing body of evidence suggesting that engaging in multiple activities, rather than any single activity, is associated with decreased readmissions.

Abstract
No research has considered a range of physician practice capabilities for managing patient care when examining practice-level influences on quality of care, utilization, and spending. Using data from the 2017 National Survey of Healthcare Organizations and Systems linked to 2017 Medicare fee-for-service claims data from attributed beneficiaries, we examined the association of practice-level capabilities with process measures of quality, utilization, and spending. In propensity score-weighted mixed-effects regression analyses, physician practice locations with "robust" capabilities had lower total spending compared to locations with "mixed" or "limited" capabilities. Quality and utilization, however, did not differ by practice-level capabilities. Physician practice locations with robust capabilities spend less on Medicare fee-for-service beneficiaries but deliver quality of care that is comparable to the quality delivered in locations with low or mixed capabilities. Reforms beyond those targeting practice capabilities, including multipayer alignment and payment reform, may be needed to support larger performance advantages for practices with robust capabilities.

Abstract
Healthcare policy in the United States (U.S.) has focused on promoting integrated healthcare to combat fragmentation (e.g., 1993 Health Security Act, 2010 Affordable Care Act). Researchers have responded by studying coordination and developing typologies of integration. Yet, after three decades, research evidence for the benefits of coordination and integration are lacking. We argue that research efforts need to refocus in three ways: (1) use social networks to study relational coordination and integrated healthcare, (2) analyze integrated healthcare at three levels of analysis (micro, meso, macro), and (3) focus on clinical integration as the most proximate impact on patient outcomes. We use examples to illustrate the utility of such refocusing and present avenues for future research.

Abstract
OBJECTIVE Musculoskeletal problems like hip and knee osteoarthritis and low-back pain are preference sensitive conditions. Patient engagement strategies (PES), such as shared decision-making and motivational interviewing, can help align patients' preferences with treatment options and potentially reduce spending. We assess the association of physician practice-level adoption of PES with utilisation and spending. DESIGN Cross-sectional study in which patients were matched across low, moderate and high levels of PES via coarsened exact matching. SETTING Primary and secondary care in 2190 physician practices. PARTICIPANTS 39 336 hip, 48 362 knee and 67 940 low-back patients who were Medicare beneficiaries were matched to the 2017-2018 National Survey of Healthcare Organizations and Systems. PRIMARY AND SECONDARY OUTCOME MEASURES Total hip replacement (THR), total knee replacement (TKR), 1-2 level posterior lumbar fusion (LF), total annual spending, components of total annual spending. RESULTS Total annual spending for patients with musculoskeletal problems did not differ for practices with low versus moderate PES, low versus high PES or moderate versus high PES, but spending was significantly lower in some categories for practices with relatively higher PES adoption. For hospital-owned and health system-owned practices, the ORs of receiving LF were 0.632 (95% CI 0.396 to 1.009) for patients attributed to practices with high PES compared with patients attributed to practices with moderate PES. For independent practices, the odds of receiving THR were 1.403 (95% CI 1.035 to 1.902) for patients attributed to practices with moderate PES compared with patients attributed to practices with low PES. CONCLUSIONS Practice-level adoption of PES for patients with musculoskeletal problems was generally not associated with total spending. PES, however, may steer patients toward evidence-based treatments. Opportunities for overall spending reduction exist as indicated by the variation in the subcomponents of total spending by PES adoption.

Abstract
More is known about the structural features of health system integration than the social features-elements of normative integration (alignment of norms) and interpersonal integration (collaboration among professionals and with patients). We surveyed practice managers and 1,360 staff and physicians at 59 practice sites within 17 health systems (828 responses; 61%). Building on prior theory, we developed and established the psychometric properties of survey measures describing normative and interpersonal integration. Normative and interpersonal integration were both consistently related to better provider experience, perceived care quality, and clinical integration (e.g., a 1-point increase in a practice's normative integration was associated with 0.53-point higher job satisfaction and 0.77-point higher perceived care quality in the practice, measured on 1 to 5 scales, p < .01). Variation in social features of integration may help explain why some health systems better integrate care, pointing to normative and interpersonal integration as potential resources for improvement.

Abstract
EXECUTIVE SUMMARY Accountable care organizations (ACOs) need confidence in their return on investment to implement changes in care delivery that prioritize seriously ill and high-cost Medicare beneficiaries. The objective of this study was to characterize spending on seriously ill beneficiaries in ACOs with Medicare Shared Savings Program (MSSP) contracts and the association of spending with ACO shared savings. The population included Medicare fee-for-service beneficiaries identified with serious illness (N = 2,109,573) using the Medicare Master Beneficiary Summary File for 100% of ACO-attributed beneficiaries linked to MSSP beneficiary files (2014-2016). Lower spending for seriously ill Medicare beneficiaries and risk-bearing contracts in ACOs were associated with achieving ACO shared savings in the MSSP. For most ACOs, the seriously ill contribute approximately half of the spending and constitute 8%-13% of the attributed population. Patient and geographic (county) factors explained $2,329 of the observed difference in per beneficiary per year spending on seriously ill beneficiaries between high- and low-spending ACOs. The remaining $12,536 may indicate variation as a result of potentially modifiable factors. Consequently, if 10% of attributed beneficiaries were seriously ill, an ACO that moved from the worst to the best quartile of per capita serious illness spending could realize a reduction of $1,200 per beneficiary per year for the ACO population overall. Though the prevalence and case mix of seriously ill populations vary across ACOs, this association suggests that care provided for seriously ill patients is an important consideration for ACOs to achieve MSSP shared savings.

Abstract
OBJECTIVE To assess the association between clinical integration and financial integration, quality-focused care delivery processes, and beneficiary utilization and outcomes. DATA SOURCES Multiphysician practices in the 2017-2018 National Survey of Healthcare Organizations and Systems (response rate 47%) and 2017 Medicare claims data. STUDY DESIGN Cross-sectional study of Medicare beneficiaries attributed to physician practices, focusing on two domains of integration: clinical (coordination of patient services, use of protocols, individual clinician measures, access to information) and financial (financial management and planning across operating units). We examined the association between integration domains, the adoption of quality-focused care delivery processes, beneficiary utilization and health-related outcomes, and price-adjusted spending using linear regression adjusting for practice and beneficiary characteristics, weighting to account for sampling and nonresponse. DATA COLLECTION/EXTRACTION METHODS 1 604 580 fee-for-service Medicare beneficiaries aged 66 or older attributed to 2113 practices. Of these, 414 209 beneficiaries were considered clinically complex (frailty or 2 + chronic conditions). PRINCIPAL FINDINGS Financial integration and clinical integration were weakly correlated (correlation coefficient = 0.19). Clinical integration was associated with significantly greater adoption of quality-focused care delivery processes, while financial integration was associated with lower adoption of these processes. Integration was not generally associated with reduced utilization or better beneficiary-level health-related outcomes, but both clinical integration and financial integration were associated with lower spending in both the complex and noncomplex cohorts: (clinical complex cohort: -$2518, [95% CI: -3324, -1712]; clinical noncomplex cohort: -$255 [95% CI: -413, -97]; financial complex cohort: -$997 [95% CI: -$1320, -$679]; and financial noncomplex cohort: -$143 [95% CI: -210, -$76]). CONCLUSIONS Higher levels of financial integration were not associated with improved care delivery or with better health-related beneficiary outcomes. Nonfinancial forms of integration deserve greater attention, as practices scoring high in clinical integration are more likely to adopt quality-focused care delivery processes and have greater associated reductions in spending in complex patients.
