HF mortality trends under Medicare readmissions reduction program at penalized and nonpenalized hospitals.
After announcement and implementation of the Medicare Hospital Readmissions Reduction Program (HRRP), 30-day readmissions declined rapidly among seniors with heart failure (HF) while 30-day mortality rose. This raised questions about whether the policy was responsible, because lower HF readmission rates have historically been associated with higher mortality. In this study, the investigators compared trends in heart failure (HF) mortality at penalized and nonpenalized hospitals nationally.

Excess mortality associated with weekend hospital admissions may be due to patient-level differences, rather than reduced staffing or services.
The author comments on a study by Walker that explained the weekend effect as arising from differences in patient characteristics among patients who present to the emergency department on the weekend. For staffing, Walker used a proxy measure because staffing information was not available. The author cautions that, although a clear rationale was provided, there should be acknowledgement that use of a proxy, whether for illness severity or staffing, may alter results.

Mortality rate estimation and standardization for public reporting: Medicare’s Hospital Compare.
The authors calibrated Bayesian recommendation systems by checking, out of sample, whether predictions aggregate to give correct general advice derived from another sample. Their process leads to substantial revisions in the Hospital Compare model for acute myocardial infarction mortality. They found that indirect standardization, as currently used by Hospital Compare, fails to adequately control for differences in patient risk factors and systematically underestimates mortality rates at the low volume hospitals. They proposed direct standardization instead.

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.

Measuring mortality performance: How did safety-net hospitals compare with other hospitals?
This study assessed mortality performance of safety-net hospitals (SNHs) using all-payer databases and measures for a broad range of conditions and procedures. It found small differences in risk-adjusted mortality rates between SNHs and non-SNHs only among teaching hospitals. After controlling for hospital factors, these differences were substantially reduced and remained significant only for surgical mortality rates.

Association of do-not-resuscitate orders and hospital mortality rate among patients with pneumonia.
The researchers evaluated the effect of analytic approaches accounting for do-not-resuscitate (DNR) status on risk-adjusted hospital mortality rates and performance rankings. They found that after accounting for patient DNR status and between-hospital variation in the association between DNR status and mortality, hospitals with higher DNR rates had lower mortality.
