The Association of Readmission Reduction Activities with Primary Care Practice Readmission Rates

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.

The Treatment with Xinfeng Capsule Can Reduce the Risk of Readmission for Patients with Rheumatoid arthritis:A Cohort Study of Approximately 10000 Individuals

Objective

The present study aimed to investigate the potential association between the treatment with Xinfeng Capsule (XFC) and the risk of readmission among patients with rheumatoid arthritis (RA).

Methods

Through a retrospective approach, data were collected from all hospitalized patients diagnosed with RA at the First Affiliated Hospital of Anhui University of Chinese Medicine between 2013 and 2021. To mitigate selection bias and confounding factors, patients were stratified into an XFC group and a Non-XFC (Non-XFC) group based on their treatment status using propensity score matching with a 1:2 ratio. Variables such as age, gender, and baseline medications were adjusted. Subsequently, the Cox proportional hazards model was employed to calculate the hazard ratio (HR) for readmission among RA patients, while Kaplan-Meier curves were utilized to depict the incidence of readmission.

Results

A total of 9987 RA patients were included in this study. Following rigorous inclusion/exclusion criteria and propensity score matching, the XFC group comprised 2036 patients, while the Non-XFC group contained 4072 patients. The Cox proportional hazards model analysis revealed that XFC acted as a protective factor, significantly reducing the risk of readmission among RA patients. Further examination of Kaplan-Meier curves demonstrated that XFC use not only effectively lowered the frequency of readmissions but also exhibited a more pronounced effect in diminishing the risk of readmission with extended usage durations (beyond 12 months). Additionally, association rule analysis underscored the strong link between XFC and freedom from readmission, as well as the robust correlation between XFC usage and significant improvements in multiple laboratory indicators, including C3, C4, CRP, ESR, and others.

Conclusion

This study underscores a robust and long-term association between XFC usage and lower readmission rates among RA patients. As a protective factor against readmission risk in these patients, the clinical value of XFC merits further promotion and investigation.

Medicare transitional care management services' association with readmissions and mortality

In 2013, the Centers for Medicare and Medicaid Services (CMS) introduced codes to reimburse outpatient providers for post-discharge transitional care management (TCM). Understanding the implications of TCM reimbursement on outcomes is crucial for evaluating CMS's investment and guiding future policy. We analyzed the association between physician organization (PO) TCM code use and post-discharge readmissions and mortality using 100% fee-for-service Medicare claims. Using a difference-in-differences approach we compared 1131 "high-TCM" POs (top quartile of TCM code use from 2015-2017) to 1133 "low-TCM" POs (bottom quartile) from before (2012) and after (2015-2017) TCM code implementation, controlling for PO and beneficiary attributes and readmission risk. TCM code use was associated with decreased 30- and 90-day readmissions (-0.31 [95%CI: -0.52, -0.09] and -0.42 [95% CI: -0.71, -0.14] percentage points, respectively), but no significant difference in mortality. Year-by-year, 2017 saw greatest readmission reduction, with a slight mortality reduction in that year only. Readmission reductions were greatest in POs not affiliated with health systems, Accountable Care Organizations (ACOs), or academic medical centers, and least in those with fewer primary care physicians. Narrow, indirect interventions like fee-for-service TCM billing code reimbursement may have limited potential to improve post-discharge outcomes overall. However, small independent practices may derive somewhat greater benefit from this support for post-discharge care.

Hospital Admission and Discharge: Lessons Learned from a Large Programme in Southwest Germany

Introduction

In the context of a GP-based care programme, we implemented an admission, discharge and follow-up programme.

Description

The VESPEERA programme consists of three sets of components: pre-admission interventions, in-hospital interventions and post-discharge interventions. It was aimed at all patients with a hospital stay participating in the GP-based care programme and was implemented in 7 hospitals and 72 general practices in southwest Germany using a range of strategies. Its' effectiveness was evaluated using readmissions within 90 days after discharge as primary outcome. Questionnaires with staff were used to explore the implementation process.

Discussion

A statistically significant effect was not found, but the effect size was similar to other interventions. Intervention fidelity was low and contextual factors affecting the implementation, amongst others, were available resources, external requirements such as legal regulations and networking between care providers. Lessons learned were derived that can aid to inform future political or scientific initiatives.

Conclusion

Structured information transfer at hospital admission and discharge makes sense but the added value in the context of a GP-based programme seems modest. Primary care teams should be involved in pre- and post-hospital care.

Incidence, patterns and risk factors for readmission following knee arthroplasty in China: A national retrospective cohort study

BACKGROUND

Limited data exist on readmission following knee arthroplasty (KA) in countries without well-established referral or extended care systems. This study aimed to investigate the incidence, patterns and risk factors for readmission following KA in China.

MATERIAL AND METHODS

In this national retrospective cohort study, we reviewed 167,265 primary KAs registered in the Hospital Quality Monitoring System in China between 2013 and 2018. Readmissions after KA within 30 and 90 days were evaluated. The causes for readmission were identified and classified as surgical or medical. The potential risk factors of readmission were assessed using multivariable logistic regression.

RESULTS

4017 (2.4%) patients readmitted within 30 days, and 7258 (4.3%) patients readmitted within 90 days. The readmission rate exhibited a downward trend during the period from 2013 to 2018 (2.7%-2.3% for 30-day readmission; 4.5%-4.2% for 90-day readmission). Surgical causes contributed to 54.3% readmissions within 30 days and 47.3% readmissions within 90 days. Wound infection/complication, joint pain, and thromboembolism were the most frequently reported reasons for surgical readmission. Older age, male sex, single marital status, non-osteoarthritis indication, a high comorbidity index, non-provincial hospitals, low hospital volume, and longer length of stay were associated with an increased risk of readmission. The geographic regions of hospitals contributed greatly to the variety of readmissions.

CONCLUSION

The readmission rate following KA decreased from 2013 to 2018. Surgery-related causes, especially wound infection/complication and pain, accounted for a large proportion. Both patient and hospital factors were associated with readmissions. Improved primary care and targeted measures are needed to help further prevent readmissions and optimize resource utilization.
