Validation of a consciousness level scale for palliative care

Palliative Medicine

Abstract

The main objective of this study is to validate a Consciousness Scale for palliative care. The scale was named Consciousness Scale for palliative care (CSPC). The validation had two phases: 1) face validity--the scale was assessed by seven healthcare professionals, both doctors and nurses, experienced in palliative care; 2) reliability and construct validity--performed by four investigators, two nurses and two doctors. The construct validation was performed by comparing the CSPC with a Visual Analogue Scale (VAS) of 100 mm, anchored in the terms 'awake' and 'unarousable', and then with the Glasgow Coma Scale (GCS). In this study, all four observers completed 44 periods of observation relative to 38 patients resulting in a total of 176 observations. In the phase of face validation, there were no discrepancies in relation to the issue: the scale provides measures for measurement; the scale can be useful to clinical practice; the scale can improve communication among professionals and the scale is easy to use. As a measure of internal consistency, Cronbach's alpha was found to be very high (0.99). The inter-rater reliability was also very high with an intraclass correlation coefficient of 0.99 (P < 0.001). The correlation of the C...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.
