The association between nurse staffing and omissions in nursing care: A systematic review.

Abstract: Aims To identify nursing care most frequently missed in acute adult inpatient wards and determine evidence for the association of missed care with nurse staffing Background Research has established associations between nurse staffing levels and adverse patient outcomes including in-hospital mortality However, the causal nature of this relationship is uncertain and omissions of nursing care (referred as missed care, care left undone or rationed care) have been proposed as a factor which may provide a more direct indicator of nurse staffing adequacy Design Systematic review Data Sources We searched the Cochrane Library, CINAHL, Embase and Medline (2006-2016) for quantitative studies of associations between staffing and missed care We searched key journals, personal libraries and reference lists of articles Review Methods Two reviewers independently selected studies Quality appraisal was based on the National Institute for Health and Care Excellence quality appraisal checklist for studies reporting correlations and associations Data were abstracted on study design, missed care prevalence and measures of association Synthesis was narrative Results Eighteen studies gave subjective reports of missed care 75% or more nurses reported omitting some care Fourteen studies found low nurse staffing levels were significantly associated with higher reports of missed care There was little evidence that adding support workers to the team reduced missed care Conclusions Low Registered Nurse staffing is associated with reports of missed nursing care in hospitals Missed care is a promising indicator of nurse staffing adequacy The extent to which the relationships observed represent actual failures is yet to be investigated This article is protected by copyright All rights reserved

Improving assessment and modelling of climate change impacts on global terrestrial biodiversity

Abstract: Understanding how species and ecosystems respond to climate change has become a major focus of ecology and conservation biology. Modelling approaches provide important tools for making future projections, but current models of the climate-biosphere interface remain overly simplistic, undermining the credibility of projections. We identify five ways in which substantial advances could be made in the next few years: (i) improving the accessibility and efficiency of biodiversity monitoring data, (ii) quantifying the main determinants of the sensitivity of species to climate change, (iii) incorporating community dynamics into projections of biodiversity responses, (iv) accounting for the influence of evolutionary processes on the response of species to climate change, and (v) improving the biophysical rule sets that define functional groupings of species in global models.

THE CLUSTERING OF MASSIVE GALAXIES AT z ∼ 0.5 FROM THE FIRST SEMESTER OF BOSS DATA

Abstract: We calculate the real- and redshift-space clustering of massive galaxies at z ∼ 0.5 using the first semester of data by the Baryon Oscillation Spectroscopic Survey (BOSS). We study the correlation functions of a sample of 44,000 massive galaxies in the redshift range 0.4
