Equivalent survival between lobectomy and segmentectomy for clinical stage IA lung cancer.
This study compared the effectiveness of lobectomy and segmentectomy for treatment of clinical stage IA (T1N0) lung cancer patients. The Society of Thoracic Surgeons General Thoracic Surgery Database was linked to Medicare data in 14,286 lung cancer patients who underwent segmentectomy (n = 1654) or lobectomy (n = 12,632) from 2002 to 2015. Survival rates were found to be similar.

Association of hospital-level intensive care unit use and outcomes in older patients with isolated rib fractures.
Researchers characterized interhospital variability in intensive care unit (ICU) vs non-ICU admission of older patients with isolated rib fractures and evaluated whether greater hospital-level use of ICU admission is associated with improved outcomes. This study included trauma patients who were admitted to trauma centers participating in the National Trauma Data Bank. The researchers found that admission location of older patients with isolated rib fractures was variable across hospitals, but hospitalization at a center with greater ICU use was associated with improved outcomes. They recommended that hospitals with low ICU use admit more such patients to an ICU.

Swamped: emergency department crowding and patient mortality.
U.S. emergency departments are experiencing extreme levels of crowding. This study estimated the impact of emergency department crowding on patient mortality. Identification relied on the abrupt crowding shocks felt by "old" emergency departments at the time a new emergency department opened nearby. Using death records linked to hospital administrative records, the investigator found that a 10% alleviation of emergency department patient volume significantly lowered the average patient's chance of mortality.

Association of use of an intravascular microaxial left ventricular assist device vs intra-aortic balloon pump with in-hospital mortality and major bleeding among patients with acute myocardial infarction complicated by cardiogenic shock.
This study examines outcomes among patients undergoing percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) complicated by cardiogenic shock. Two interventions are compared: intravascular microaxial left ventricular assist devices (LVADs) versus intra-aortic balloon pumps (IABPs). The American College of Cardiology’s National Cardiovascular Data Registry was used to identify patients with AMI complicated by cardiogenic shock from hospitals participating in the CathPCI and Chest Pain-MI registries and identified 28,304 patients. Over the study period (2015 to 2017), LVAD was used in 6.2% of patients and IABP in 29.9%. LVAD was shown to have higher rates of in-hospital death and major bleeding complications compared to IABP.

Frailty as a predictor of death or new disability after surgery: a prospective cohort study.
The purpose of this study was to compare the accuracy of the modified Fried Index (mFI) and the Clinical Frailty Scale (CFS) to predict death or patient-reported new disability 90 days after major elective surgery. Results showed that older people with frailty are significantly more likely to die or experience a new patient-reported disability after surgery and that although accuracy was similar, the CFS, compared to the mFI, was easier to use and feasibility was higher.

Utilization of intensive care unit nutrition consultation is associated with reduced mortality.
The aim of this project was to investigate the prevalence of nutrition consultation (NC) in U.S. intensive care units (ICUs) and to examine its association with patient outcomes. Data from the Healthcare Cost and Utilization Project's state inpatient databases was utilized from 2010 - 2014. A multilevel logistic regression model was used to evaluate the relationship between NC and clinical outcomes. The investigators concluded that rates of NC were low in critically ill patients.

Premature mortality among adults with schizophrenia in the United States.
The objective of the study was to describe overall and cause-specific mortality rates and standardized mortality ratios for adults with schizophrenia compared with the US general population. In a US national cohort of adults with schizophrenia, excess deaths from cardiovascular and respiratory diseases implicate modifiable cardiovascular risk factors, including especially tobacco use.

Residential racial segregation and mortality among black, white, and Hispanic urban breast cancer patients in Texas, 1995 to 2009.
The authors investigated whether residential segregation was associated with mortality among urban women with breast cancer. They found that greater black segregation and Hispanic segregation were adversely associated with cause-specific mortality and all-cause mortality.

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.

Does the use of neoadjuvant therapy for pancreatic adenocarcinoma increase postoperative morbidity and mortality rates?
The researchers used data from the NSQIP Pancreatectomy Demonstration Project (11/2011 to 12/2012) to identify patients with pancreatic adenocarcinoma who did and did not receive neoadjuvant therapy. They found that despite evidence for more extensive disease, patients receiving neoadjuvant therapy did not experience more complications. Neoadjuvant radiation was associated with lower pancreatic fistula rates.

Early mortality after aortic valve replacement with mechanical prosthetic vs bioprosthetic valves among Medicare beneficiaries: a population-based cohort study.
The researchers compared early mortality after aortic valve replacement (AVR) between the recipients of mechanical and bioprosthetic aortic valves. Among 66,453 Medicare beneficiaries who received AVRs, use of mechanical valves was associated with a higher risk for death on the date of surgery and within 30 days compared with the bioprosthetic aortic valves. However, this applied only to those who underwent concurrent AVR and coronary artery bypass graft but not isolated AVR.

Outcomes of patients with healthcare-associated pneumonia: worse disease or sicker patients?
The researchers sought to determine the contribution of healthcare-associated pneumonia (HCAP) criteria to case-fatality rate. They found that, after adjustment for differences in patient characteristics, HCAP was associated with greater case-fatality rate than community-acquired pneumonia, possibly due to HCAP organisms or to HCAP criteria themselves.

Severity-adjusted mortality in trauma patients transported by police.
Two decades ago, Philadelphia began allowing police transport of patients with penetrating trauma. In this retrospective cohort study, the investigators conduct a large, multiyear, citywide analysis of this policy. They examine the association between mode of out-of-hospital transport (police department versus emergency medical services [EMS]) and mortality among patients with penetrating trauma in Philadelphia.
