Variation in the rates of do not resuscitate orders after major trauma and the impact of intensive care unit environment

Abstract

There is an increased emphasis on benchmarking of trauma mortality outcomes as a measure of quality. Differences in approaches to end-of-life care or perceptions of salvageability might account for some of the variability in outcomes across centers. We postulated that these differences in perceptions or practice might lead to significant variation in the use of do not resuscitate (DNR) orders and sought to identify institutional characteristics associated with their use. Patients surviving >24 hours and admitted to an intensive care unit (ICU) in one of 68 centers across the United States were identified from a large prospective cohort study of severely injured patients. Independent predictors of a DNR order at both the patient and institutional level were identified using multivariate hierarchical modeling stratified by age <55 or >/=55. Of 6,765 patients, 7% had a DNR order, of whom 88% died. The proportion of patients in each center with a DNR order ranged from 0% to 57%. Independent patient-level predictors associated with a DNR order were increasing age, preinjury comorbidity burden, severe injury, and organ failure. Institutional predictors of DNR orders differed by age. Care in an open ICU was associated with a DNR order...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
