Main features and control strategies to reduce overcrowding in emergency departments. A systematic review of the literature

Purpose: Overcrowding is a problem that affects emergency departments (ED) all over the world; it occurs due to a disproportion between user demand and the physical, human and structural resources available. Essential prerequisites to assessing and managing the phenomenon are its accurate measurement and an understanding of its impact. The objective of this systematic review is to identify the characteristics of the problem, analyzing the proposed strategies aimed at improving patient flow, delay in services provided and overcrowding of emergency departments. Methods: To achieve our objectives, a manual computerized search was performed in the bibliographic databases using as keywords “Emergency Department”, “Overcrowding”, “Emergency Room”, “Emergency Service”, “Emergency Unit”“,Emergency Ward”, “Emergency Outpatient Unit”, “Emergency Hospital”, “Crowding”, “Mass Gathering”, “Management” and “Comprehensive Health Care”. Two independent reviewers analyzed abstracts, titles and full text articles for admissibility, according to the selected inclusion and exclusion criteria. Results: The process lead to include 19 articles. It was possible to group the solutions proposed in five categories: work organization, investment in primary care, creation of new dedicated professional figures, work and structural modifications and implementation of predictive simulation models using mathematical algorithms. Conclusion: The most effective measures to guarantee an improvement in the flow of patients are represented by both improving the efficiency of human resources and by developing predictive mathematical models, regardless of the type of hospital and its location. Considering the complexity of EDs and the multiple characteristics of overcrowding and that the causes of crowding are different and site-specific, a careful examination of the specifics of each ED is necessary to identify improving fields

Prevalence and risk factors of sarcopenia among nursing home older residents

Sarcopenia has been indicated as a reliable marker of frailty and poor prognosis among the oldest individuals. At present, there are no data on sarcopenia in nursing home population. We evaluated the prevalence of sarcopenia and its association with functional and clinical status in a population of elderly persons aged 70 years and older living in nursing homes

Proinflammatory genetic profiles in subjects with history of ischemic stroke.

BACKGROUND AND PURPOSE: Proinflammatory genetic profiles, resulting from the combination of single nucleotide polymorphisms in genes encoding inflammatory molecules, may contribute to the development and progression of cardiovascular diseases. We evaluated the association between history of ischemic stroke and genetic profiles determined by the synergistic effects of polymorphisms in genes encoding prototypical inflammatory proteins. METHODS: The study included 237 individuals with history of ischemic stroke and 223 age-matched and gender-matched controls. The polymorphisms of the C-reactive protein (CRP), interleukin-6 (IL-6), macrophage migration inhibitory factor (MIF), monocyte chemoattractant protein-1 (MCP-1), intercellular adhesion molecule-1 (ICAM-1), E-selectin (E-sel), and matrix metalloproteinase-3 (MMP-3) genes were studied. RESULTS: IL-6 GG, IL-6 GC, MCP-1 GG, ICAM-1 EE, E-sel AA, and MMP-3 5A5A genotypes were significantly and independently associated with stroke history. The odds of stroke increased with the number of high-risk genotypes: carrying 1 proinflammatory gene variant conferred a risk of 3.3 (1.6 to 6.9), whereas individuals concomitantly carrying 2 and 3 proinflammatory gene variants had adjusted odds ratios of 21.0 (7.6 to 57.5) and 50.3 (10.2 to 248.1), respectively. CONCLUSIONS: Proinflammatory genetic profiles are significantly more common in subjects with stroke history. Synergistic effects between proinflammatory genotypes might be potential markers for cerebrovascular diseases

Monocyte chemoattractant protein-1 (MCP-1) gene polymorphism and risk of Alzheimer's disease in Italians.

Monocyte chemoattractant protein-1 (MCP-1) is a key molecule for monocyte chemotaxis and tissue extravasation and for the modulation of leukocyte function during inflammation. Upregulation of MCP-1 may occur in the brain of subjects affected by Alzheimer's disease (AD) and MCP-1 levels in plasma and cerebrospinal fluid have been proposed as biological markers for the inflammatory process that accompanies AD pathogenesis. Importantly, serum levels and biological activity of MCP-1 protein are strongly influenced by a single nucleotide polymorphism occurring at position -2518 of the MCP-1 gene promoter. A recent study has investigated the possible association between this gene polymorphism and AD in a Spanish population, with negative results. Here, we performed a case-control study to test whether the risk for AD might be influenced by the -2518 A/G polymorphism of the MCP-1 gene in an ethnically homogeneous Italian population. The GG genotype and the G allele of the MCP-1 gene polymorphism were significantly more common in the AD group than in control individuals (P<0.0001) A logistic regression analysis indicated that the GG genotype was an independent risk factor for AD in our population. This effect was not influenced by the presence of the APOE 4 high-risk allele, nor by the presence of other gene variations associated with a pro-inflammatory phenotype. These findings indicate that the -2518 A/G polymorphism of the MCP-1 gene is associated with AD in Italians and confirm that inflammatory gene variations may be important contributors in the development and progression of neurodegenerative disorders
