Performance Of Safety-Net Hospitals In Year 1 Of The Comprehensive Care For Joint Replacement Model.

ABSTRACT: The Comprehensive Care for Joint Replacement (CJR) model introduced in 2016 aims to improve the quality and costs of care for Medicare beneficiaries undergoing hip and knee replacements. However, there are concerns that the safety-net hospitals that care for the greatest number of vulnerable patients may perform poorly in CJR. In this study we used Medicare's CJR data to evaluate the performance of 792 hospitals mandated to participate in the first year of CJR. We found that in comparison to non-safety-net hospitals, 42 percent fewer safety-net hospitals qualified for rewards based on their quality and spending performance (33 percent of safety-net hospitals qualified, compared to 57 percent of non-safety-net hospitals), and safety-net hospitals' rewards per episode were 39 percent smaller ($456 compared to $743). Continuation of this performance trend could place safety-net hospitals at increased risk of penalties in future years. Medicare and hospital strategies such as those that reward high-quality care for vulnerable patients could enable safety-net hospitals to compete effectively in CJR.

Project description:ObjectiveTo determine whether the Comprehensive Care for Joint Replacement (CJR) model, a mandatory episode-based payment program for knee and hip replacement surgery, affected patient-reported measures of quality.Data sourcesSurveys of Medicare fee-for-service beneficiaries who had hip or knee replacement surgery, collected between July 2018 and March 2019, secondary Medicare administrative data, the Provider of Services file, CJR and Bundled Payments for Care Improvement participant lists from the Centers for Medicare & Medicaid Services, and the Area Health Resource Files.Study designIn 2018, participation in the CJR model was mandatory for nearly all hospitals in 34 randomly selected, metropolitan statistical areas (MSAs) that had high historical Medicare payments for lower-extremity joint replacements surgery. The control group included 47 high-payment MSAs randomly assigned as controls. We estimated risk-adjusted differences in self-reported measures of functional status and pain, satisfaction with care, and caregiver help between respondents in CJR hospitals and respondents in hospitals located in the control group.Data collectionWe selected a census of CJR patients and an equal number of control patients to survey. We fielded two waves of surveys using a mail and phone protocol, yielding 8433 CJR and 9014 control respondents.Principal findingsCJR respondents were slightly more likely to depend on caregivers for certain activities of daily living when they got home (either directly from the hospital or after an institutional post-acute care stay). On a 100-point scale, differences ranged from -2.6 points (p < 0.01) for help needed bathing to -1.7 points (p < 0.05) for help needed using the toilet. However, differences in eight measures of self-reported functional status approximately 90-120 days after hospital discharge were not statistically significant, ranging from -1.1% (p = 0.087) to 0.7% (p = 0.437).ConclusionsCJR did not harm patient health or affect patient satisfaction on average but did increase reliance on caregivers during recovery.

Project description:BackgroundSafety-net hospitals care for a high proportion of uninsured/underinsured patients who may lack access to longitudinal care. The present study characterized the use of mechanical valves and clinical outcomes of surgical aortic valve replacement at safety net hospitals.MethodsAll adults undergoing surgical aortic valve replacement were abstracted from the 2016-2018 Nationwide Readmissions Database. Hospitals were divided into quartiles based on volume of all Medicaid and uninsured admissions, with the highest quartile defined as safety net hospitals. Multivariable regression was used to determine the association between safety net hospitals and several outcomes including mechanical valve use, perioperative complications, index hospitalization costs, 90-day readmission, and complications at readmission.ResultsOf the 94,580 patients undergoing surgical aortic valve replacement, 14.5% of operations were at safety net hospitals. Patients at safety net hospitals more commonly received mechanical valves (20.3% vs 16.9%, P < .01) compared to those at non-safety net hospitals. After adjustment, safety net hospitals remained associated with a greater odds of mechanical aortic valve use (adjusted odds ratio, 1.13, 95% confidence interval 1.05-1.21). However, operation at safety net hospitals was also associated with increased odds of perioperative complications (adjusted odds ratio 1.10, 95% confidence interval 1.03-1.17) and higher hospitalization costs (β coefficient +$6.15K, 95% confidence interval +$5.26 - +$7.03) despite similar 90-day readmissions. Upon readmission, safety net hospitals patients were more likely to experience mortality (adjusted odds ratio 1.87, 95% confidence interval 1.18-2.98) and stroke (adjusted odds ratio 2.41, 95% confidence interval 1.23-4.70) compared to those at non-safety net hospitals.ConclusionHospital safety net status is associated with increased use of mechanical valves for surgical aortic valve replacement despite also being associated with increased perioperative complications, costs, and significant complications upon readmission. Ability to access adequate follow-up care may be an important consideration for surgical aortic valve replacement at safety net hospitals.

Project description:ImportancePrior research concluded that institutional postacute care spending decreased under the Comprehensive Care for Joint Replacement (CJR) model. Less is known about how changes in institutional postacute care spending varied across different types of hospitals.ObjectiveTo measure hospital-level heterogeneity in the association of the CJR model with changes in institutional postacute care spending and to identify hospital characteristics associated with this variation.Design setting and participantsUsing 100% Medicare claims data, this cross-sectional study assessed institutional postacute care spending from 2016 to 2017 among US hospitals randomly selected to participate in the CJR model and control group hospitals that were eligible but not selected for the participation in the CJR model. A causal forest was used to estimate the treatment effect of the CJR model conditional on hospital characteristics. Analysis was conducted between October 2019 and October 2021.Main outcomes and measuresThe unit of analysis was each hospital; the outcome was the average per-episode Medicare spending for institutional postacute care within 90 days after hospital discharge for hip or knee joint replacement.ResultsThis study included 531 CJR participating hospitals and 658 control group hospitals from 2016 to 2017. The CJR model was associated with a $761 reduction in institutional postacute care spending (95% CI, -$1172 to -$351). The reduction in spending under the CJR model did not vary across conditional on hospital characteristics. Limited evidence was found for greater savings among hospitals with higher pre-CJR spending. However, this finding did not hold for hospitals in the highest quintile of pre-CJR spending.Conclusions and relevanceIn this cross-sectional study of 1189 hospitals, findings did not show strong evidence for significant heterogeneity in how the CJR model was associated with reductions in institutional postacute care spending across a range of hospital characteristics. Savings were not concentrated in hospitals with specific characteristics, such as hospitals with high-volume joint replacement or hospitals serving less medically or socially complex patients. Findings suggest that the CJR model created opportunities for savings across a spectrum of different hospitals.
