Abstract

Importance: Aortic stenosis (AS) is one of the most common heart valve conditions and its incidence and prevalence increases with age. With the introduction of transcatheter aortic valve replacement (TAVR), racial and ethnic disparities in AS diagnosis, treatment and outcomes is poorly understood. Objective: In this study we assessed racial and ethnic disparities in AS diagnosis, treatment, and outcomes among Medicare beneficiaries. Design: We conducted a population-based cohort study of inpatient, outpatient, and professional claims from a 20% sample of Medicare beneficiaries Main outcomes and measures: Incidence and Prevalence was determined among Medicare Beneficiaries. Outcomes in this study included management; the number of (non)-interventional cardiology and cardiothoracic surgery evaluation and management (E&M) visits, and number of transthoracic echocardiograms (TTE) performed. Treatment, which was defined as Surgical Aortic Valve Replacement and Transthoracic Aortic Valve Replacement. And outcomes described as All-cause Hospitalizations, Heart Failure Hospitalization and 1-year mortality. Results: A total of 1,513,455 Medicare beneficiaries were diagnosed with AS (91.3% White, 4.5% Black, 1.1% Hispanic, 3.1% Asian and North American Native) between 2010 and 2018. Annual prevalence of AS diagnosis was lower for racial and ethnic minorities compared with White patients, with adjusted rate ratios of 0.66 (95% CI 0.65 to 0.68) for Black patients, 0.67 (95% CI 0.64 to 0.70) for Hispanic patients and 0.75 (95% CI 0.73 to 0.77) for Asian and North American Native patients as recent as 2018. After adjusting for age, sex and comorbidities, cardiothoracic surgery E&M visits and treatment rates were significantly lower for Black, Hispanic and Asian and North American Native patients compared with White patients. All-cause hospitalization rate was higher for Black and Hispanic patients compared with White patient. 1-year mortality was higher for Black patients, while Hispanic and Asian and North American Native patients had lower 1-year mortality compared with White patients. Conclusions and relevance: We demonstrated significant racial and ethnic disparities in the diagnosis, management and outcomes of AS. The factors driving the persistence of these disparities in AS care need to be elucidated to develop an equitable health care system. [ABSTRACT FROM AUTHOR]

Abstract

Cardiac surgery remains highly morbid and requires significant postoperative care. The use of postacute care facilities, such as skilled nursing facilities (SNFs) has grown in popularity to reduce healthcare spendings. Currently, sex and race disparities associated with SNF use after cardiac surgery are poorly understood. Patients who underwent coronary artery bypass graftingfrom June 2016 to December 2018 were identified in Medicare Provider Analysis and Review data. Patients were stratified into 4 groups based on sex and race as follows: White male, White female, Black male, and Black female. The impact of sex and race on SNF use and the associated outcomes were evaluated using logistic regression and Cox-proportional hazards analysis. Of the 93,727 patients who underwent coronary artery bypass grafting, 67,244 (71.7%) were White males, 2517 (2.7%) were Black males, 22,187 (23.7%) were White females, and 1779 (1.9%) were Black females. Black female patients (37.1%) were most likely to be discharged to SNF, followed by White females (33.7%), Black males (24.9%), and White males (18.9%) (P < 0.001). After adjustment, Black males (OR = 1.34, 95% CI: 1.21-1.49), White females (OR = 1.82, 95% CI: 1.75-2.13), and Black females (OR = 1.90, 95% CI: 1.70-2.13) were more likely to be discharged to SNF compared to White males. However, of the patients discharged to SNF, only White females and Black females had better overall survival when compared to White men. Significant disparities in the use of SNF after cardiac surgery are present across sex and race categories; however, the 1-y mortality benefit after risk adjustment does not reflect these differences.

Abstract

Under the Comprehensive Care for Joint Replacement (CJR) model, hospitals are held accountable for nearly all Medicare payments that occur during the initial hospitalization until 90 days after hospital discharge (ie, the episode of care). It is not known whether unrelated expenditures resulting from this "broad" definition of an episode of care will affect participating hospitals' average episode-of-care payments.To compare the CJR program's broad definition of an episode of care with a clinically narrow definition of an episode of care.We identified Medicare claims for 23 251 patients in Michigan who were Medicare beneficiaries and who underwent joint replacement during the period from 2011 through 2013 at hospitals located in metropolitan statistical areas. Using specifications from the CJR model and the clinically narrow Hospital Compare payment measure, we constructed episodes of care and calculated 90-day episode payments. We then compared hospitals' average 90-day episode payments using the 2 definitions of an episode of care and fit linear regression models to understand whether payment differences were associated with specific hospital characteristics (average Centers for MedicareMedicaid Services-hierarchical condition categories risk score, rural hospital status, joint replacement volume, percentage of Medicaid discharges, teaching hospital status, number of beds, percentage of joint replacements performed on African American patients, and median income of the hospital's county). We performed analyses from July 1 through October 1, 2015.The correlation and difference between average 90-day episode payments using the broad definition of an episode of care in the CJR model and the clinically narrow Hospital Compare definition of an episode of care.We identified 23 251 joint replacements (ie, episodes of care). The 90-day episode payments using the broad definition of the CJR model ranged from $17 349 to $29 465 (mean [SD] payment, $22 122 [$2600]). Episode payments were slightly lower (mean payment, $21 670) when the Hospital Compare definition was used. Both methods were strongly correlated (r = 0.99, P .001). The average payment difference between these 2 types of episodes of care was small (mean [SD], $452 [$177]; range, $73-$1006). In our multivariable analysis, we found that the hospital characteristics examined had a minimal impact or no impact on the payment differential.The average 90-day episode payments determined by both definitions of an episode of care were strongly correlated, and there was a small payment differential for most hospitals. In the context of joint replacement bundled payments, these data suggest that hospital performance will be consistent whether a broad or clinically narrow definition of an episode of care is used.
