Racial and ethnic disparities in hospitalization outcomes among Medicare beneficiaries during the COVID-19 pandemic.
This study assessed assess racial and ethnic differences in hospitalization outcomes during the COVID-19 pandemic among Medicare beneficiaries. Medicare claims from the Social Security Administration was used to determine in-hospital mortality and mortality inclusive of discharges to hospice and discharges to postacute care. Over 31 million Medicare recipients in the database were analyzed with over 14 million hospitalizations from January 2019 to February 2021. There was a decline in non-COVID-19 and an emergence of COVID-19 hospitalizations among beneficiaries of different racial and ethnic minority groups through February 2021. In-hospital mortality was not significantly different among Black patients relative to White patients but was 3.5 percentage points higher among Hispanic patients and other racial and ethnic minority groups. There were disparities in discharges to hospice and postacute care as well.

Changes in hospital-acquired conditions and mortality associated with the hospital-acquired condition reduction program.
This study evaluated changes in Hospital-Acquired Conditions (HACs) and 30-day mortality after the announcement of the Centers for Medicare and Medicare Services’ Hospital-Acquired Condition Reduction Program (HACRP) in August 2013. The authors evaluated models to test for changes in HACs and 30-day mortality before and after the Affordable Care Act (ACA), and after the HACRP. Fee-for-service Medicare claims from 2009 to 2015 were used. The HAC rate declined after the ACA was passed and declined further after the HACRP announcement. However, 30-day mortality rates were unchanged.

Improvement in activities of daily living during a nursing home stay and one-year mortality among older adults with sepsis.
This study looked at the association between recovery of activities of daily living (ADLs) during a skilled nursing facility (SNF) stay and 1-year mortality after SNF discharge among Medicare beneficiaries treated in intensive care for sepsis. This retrospective cohort study identified 59,383 Medicare beneficiaries who were admitted to an SNF within 3 days of discharge from hospitalization that included time in an ICU for sepsis from all of 2013 to October 2015. About 58% of SNF residents showed improvement in ADL function. The higher the improvement in ADL score the less the mortality risk compared to residents who did not improve.

Prior cancer does not adversely affect survival in locally advanced lung cancer: a national SEER-Medicare analysis.
Researchers identified patients > 65 years of age diagnosed 1992-2009 with locally advanced lung cancer in the Surveillance, Epidemiology, and End Results-Medicare linked dataset. They found that, for patients with locally advanced lung cancer, prior cancer does not adversely impact clinical outcomes. Patients with locally advanced lung cancer and a history of prior cancer should not be excluded from clinical trials.

Association between hospital performance on patient safety and 30-day mortality and unplanned readmission for Medicare fee-for-service patients with acute myocardial infarction.
The researchers studied the relationship between hospital performance on adverse event rates and hospital performance on 30-day mortality and unplanned readmission rates for Medicare fee-for-service patients hospitalized for acute myocardial infarction (AMI). They found that for Medicare fee-for-service patients discharged with AMI, hospitals with poorer patient safety performance were also more likely to have poorer performance on 30-day all-cause mortality and on unplanned readmissions.

National trends in heart failure hospitalization after acute myocardial infarction for Medicare beneficiaries: 1998-2010.
This study used a complete national sample of 2 789 943 AMI hospitalizations of Medicare fee-for-service beneficiaries from 1998 through 2010, we evaluated annual changes in the incidence of subsequent heart failure (HF) hospitalization and mortality using Poisson and survival analysis models. It found that HF hospitalization after AMI decreased from 1998 to 2010, which may indicate improvements in the management of AMI.

Improving Medicare's Hospital Compare mortality model.
The researchers sought to improve the predictions provided by Medicare's Hospital Compare (HC) to facilitate better informed decisions regarding hospital choice by the public. Their model produces very different predictions from the current HC model, with higher predicted mortality rates at hospitals with lower volume and worse characteristics. The expanded model would advise patients against seeking treatment at the smallest hospitals with worse technology and staffing.
