Hospital case volume is associated with improved survival for patients with metastatic melanoma.
This study investigated the influence of hospital case volume on malignant melanoma survival and treatment utilization. The researchers discovered that for patients diagnosed with metastatic melanoma, being treated in a high-volume hospital was associated with an improvement in survival and lower utilization of chemotherapy, immunotherapy, surgery, and radiation therapy.

Relative impact of surgeon and hospital volume on operative mortality and complications following pancreatic resection in Medicare patients.
This study's objective was to evaluate the relative effects of surgeon and hospital volume on mortality and complications after pancreatic resection among older patients. The researchers used Texas Medicare data and found that high surgeon volume and high hospital volume were associated with lower risk of mortality, while high surgeon volume was also associated with lower risk of complications.

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.

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.

Electronic health records and quality of care: an observational study modeling impact on mortality, readmissions, and complications.
The authors assessed the relationship between electronic health records (EHR) adoption and patient outcomes. Their results indicate that patients receiving medical and surgical care at hospitals with no EHR system have similar outcomes compared to patients seeking care at hospitals with a full EHR system. They concluded that EHRs may play a smaller role than expected in patient outcomes and overall quality of care.

Incidence and in-hospital mortality of acute kidney injury (AKI) and dialysis-requiring AKI (AKI-D) after cardiac catheterization in the National Inpatient Sample.
This study examined cardiac catheterization or percutaneous coronary intervention (PCI) hospital discharges from the nationally representative National Inpatient Sample to determine annual population incidence rates for AKI and AKI-D in the United States from 2001 to 2011. It found that the incidence of AKI among cardiac catheterization and PCI patients has increased sharply in the United States; however, mortality has significantly declined.

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.
