Comparing perioperative processes of care in high and low mortality centers performing pancreatic surgery.
The researchers compared high and low mortality hospitals in order to identify differences in patient care impacting safety. They concluded that high and low mortality hospitals both have high compliance with common quality measures; however, high mortality hospitals performed worse in other areas of perioperative care, indicating possible targets for quality improvement efforts.

Lung cancer resection at hospitals with high vs low mortality rates.
The objective of this study was to evaluate perioperative outcomes in patients who underwent lung cancer resection at high-mortality hospitals [HMHs] and low-mortality hospitals [LMHs]) in order to better understand the factors related to differences in mortality rates after lung cancer resection. It concluded that failure-to-rescue rates are higher at HMHs, which may explain the large differences between hospitals in mortality rates following lung cancer resection.

Readmission predicts 90-day mortality after esophagectomy: analysis of surveillance, epidemiology, and end results registry linked to Medicare outcomes.
The purpose of this study was to characterize postesophagectomy readmissions and determine their relationship with subsequent 90-day mortality. It found that one in 5 esophagectomy patients are readmitted early after discharge. Readmitted patients have a 5-fold increase in early mortality.

Variation in the contents of sepsis bundles and quality measures. a systematic review.
The researchers sought to determine the degree of agreement on component elements of sepsis bundles and the associated timing goals for completion of each element. They also evaluated the amount of variation between metrics associated with bundles. They found that no bundle included metrics evaluating timeliness or completeness of sepsis recognition. Also, there was a lack of consensus on component elements and timing goals across highly recognized sepsis bundles.

Prophylactic inferior vena cava filter placement does not result in a survival benefit for trauma patients.
The researchers examined the relationship between prophylactic inferior vena cava (IVC) filter use, mortality, and venous thromboembolic events (VTE). They found that high rates of prophylactic IVC filter placement have no effect on reducing trauma patient mortality and are associated with an increase in deep venous thromboembolism (DVT) events.

Readmission destination and risk of mortality after major surgery: an observational cohort study.
This study examined the association between readmission destination and mortality risk in the USA in Medicare beneficiaries after a range of common operations. It found that patients who are readmitted to hospital after various major operations consistently achieve improved survival if they return to the hospital where their surgery took place.

Mortality associated with medical therapy versus elective colectomy in ulcerative colitis: a cohort study.
This study sought to determine whether patients with advanced ulcerative colitis (UC) treated with elective colectomy have improved survival compared with those treated with medical therapy. It found that elective colectomy was associated with improved survival compared with long-term medical therapy, although this result did not remain statistically significant in all sensitivity analyses.

Pulmonary support on day of life 30 is a strong predictor of increased 1 and 5-year morbidity in survivors of congenital diaphragmatic hernia.
The researchers aimed to determine if the degree of pulmonary support (PS) on day of life 30 (DOL-30) could be a simple cross-institutional tool for identifying those patients with a higher risk of long-term morbidity. They found that PS on DOL-30 is a strong independent predictor of morbidity at 1 and 5-years and may be used as a simple prognostic tool to identify high-risk infants.

Surgeon case volume and 30-day mortality after carotid endarterectomy among contemporary medicare beneficiaries: before and after national coverage determination for carotid artery stenting.
The objective of this study is to examine the decline in past-year case-volumes of surgeons performing carotid endarterectomy (CEA) before and after the National Coverage Determination (NCD) for carotid artery stenting (CAS) and to assess its effect on 30-day post-CEA mortality. It found that the rate of CEA procedures decreased substantially during 2001 to 2008. The postprocedural mortality in Medicare beneficiaries was high compared with trial patients.

Multimorbidity redefined: prospective health outcomes and the cumulative effect of co-occurring conditions.
The researchers explored the prospective effects of multimorbidity on health outcomes (health status, major health decline, and mortality). They found a strong and significant association between multimorbidity and prospective health status, major health decline, and mortality and concluded that multimorbidity may be used — both in clinical practice and in research — to identify older adults with heightened vulnerability for adverse outcomes.

Correlation between the international consensus definition of the Cancer Anorexia-Cachexia Syndrome (CACS) and patient-centered outcomes in advanced non-small cell lung cancer.
The researchers applied the recently posed weight-based international consensus CACS definition to a population of patients with advanced non-small cell lung cancer (NSCLC) and explored its impact on patient-reported outcomes. They concluded that it is useful in identifying patients with advanced NSCLC who are likely to have significantly inferior survival and who will develop more precipitous declines in physical function and QOL.

Nighttime intensivist staffing, mortality, and limits on life support: a retrospective cohort study.
This study assesses whether the relationships between nighttime staffing models and clinical outcomes are mediated by differences in end-of-life decision-making. It found little evidence that nighttime physician staffing models affect patient outcomes. ICUs without physicians at night may exhibit reduced hospital mortality that is possibly attributable to differences in end-of-life care practices.

The effect of graft type on mortality in liver transplantation for hepatocellular carcinoma.
The researchers aimed to: (1) examine the risk of mortality in liver transplantation for hepatocellular carcinoma (HCC), (2) to establish if this risk is affected by partial graft use, and (3) to determine if this effect is mitigated by improved tumor-associated risk stratification. They found that the risk of mortality following LT does not differ by the type of graft used in recipients with favorable-risk HCC or those without HCC.

Validation study of medicare claims to identify older US adults with CKD using the Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study.
The researchers compared characteristics and outcomes for individuals with chronic kidney disease (CKD) defined using laboratory measurements versus claims data from 6,982 study participants who had Medicare fee-for-service coverage. They found that CKD, whether identified using a claims-based algorithm or through estimated glomerular filtration rate or albumin-creatinine ratio measurements, is associated with increased risk for all-cause mortality and end-stage renal disease (ESRD).

Donor hepatitis C sero-status does not impact survival in liver transplantation.
The researchers sought to assess the impact of both donor and recipient HCV status on patient and graft survival. They found that the use of HCV+ grafts in HCV+ recipients is not associated with worse outcomes. They conclude that with the increase in HCV+patients awaiting an organ, more consideration should be given to HCV+ donors.

Statin therapy after infrainguinal bypass surgery for critical limb ischemia is associated with improved 5-year survival.
The aim of this study was to determine the effect of long-term statin use after lower extremity bypass grafting on patient-related and graft-related outcomes. It found that statin therapy is associated with a 5-year survival benefit after lower extremity bypass in patients with critical limb ischemia. However, 1-year limb-related outcomes were not influenced by statin use in our large observational cohort of patients undergoing revascularization in New England.

Treatment of diffuse large B-cell lymphoma in the elderly: regimens without anthracyclines are common and not futile.
This study characterized treatment choices and compared the 3-year overall survival rates of 8262 Medicare beneficiaries diagnosed with diffuse large B-cell lymphoma in 2000 – 2006. It found that patients treated with anthracycline-containing regimens with rituximab have the highest survival rates when all available clinical features are accounted for.
