Traumatic brain injury (TBI) patients are known to be at high risk for venous thromboembolic events (VTEs). The Brain Trauma Foundation Guidelines (2007) state that low-molecular-weight heparin or unfractionated should used prevent VTE complications, but suggest there is an increased of expansion intracranial hemorrhages (ICH) with prophylaxis. In addition, it unclear which treatment regimen (i.e., medication, dose, and timing) provides the best risk:benefit ratio in TBI patients. We...

The Brain Trauma Foundation has published guidelines on the surgical management of traumatic subdural hematoma (SDH). However, no data exist proportion patients with SDH that can be selected for conservative and what is outcome these patients. goals this study were as follows: 1) to establish are initially treated conservatively; 2) determine will deteriorate require evacuation; 3) identify risk factors associated deterioration delayed surgery.All cases acute (869 when inclusion criteria...

Abstract: Background: Intracranial hypertension can cause secondary damage after a traumatic brain injury. Aggressive medical management might not be sufficient to alleviate the increasing intracranial pressure (ICP), and decompressive craniectomy (DC) considered. Decompressive divided into categories, according timing rationale for performing procedure: primary (done at time of mass lesion evacuation) treat refractory ICP). Most studies analyze DC together. Our hypothesis is that these two...

Aim & Background: Strategic planning has been presented as an important management practice. However, evidence of its deployment in healthcare systems low-income and middle-income countries (LMICs) is limited. This study investigated the strategic process Iranian hospitals. Methods: The present was accomplished 24 teaching hospitals Tehran, Iran from September 2012 to March 2013. data collection instrument a questionnaire including 130 items. measured situation formulation, implementation,...

The American Academy of Neurology recommended using phenytoin or carbamazepine to prevent early post-traumatic seizures (PTS) in severe traumatic brain injuries (TBI). In this study, we examined the effects prophylaxis on mild, moderate, and TBIs. There have been no studies looking at compliance rate side systematic use a large population scale. goal study is determine 1) proportion TBI patients receiving prophylaxis; 2) which parameters decided when decide administer phenytoin; 3) efficacy...

In this paper first we apply ranked set sampling (RSS) procedure in joint monitoring of both process mean and variance. Then, study the effect measurement error on variance when simple random (SRS) as well RSS is used. The results prove that can seriously deteriorate ability control chart detecting all out‐of‐control scenarios. also represent using improve scheme shifts, shifts either exists or not. other words, reduce adverse scheme. After that, utilize multiple measurements at each sample...

The effect of parameters estimation on profile monitoring methods has only been studied by a few researchers and the assumption normal response variable tackled. However, in some practical situation, normality is violated follows discrete distribution such as Poisson. In this paper, we evaluate Phase II Poisson regression profiles considering two control charts, namely Hotelling’s T2 multivariate exponentially weighted moving average (MEWMA) charts. Simulation studies terms run length (ARL)...

In this paper, we investigate the misleading effect of measurement errors on simultaneous monitoring multivariate process mean and variability. For purpose, incorporate into a hybrid method based generalized likelihood ratio (GLR) exponentially weighted moving average (EWMA) control charts. After that, propose four remedial methods to decrease effects performance procedure. The procedure as well proposed is investigated through extensive simulation studies real data example.

This paper introduces a Markov model in Phase II profile monitoring with autocorrelated binary response variable. In the proposed approach, logistic regression is extended to describe within-profile autocorrelation. The likelihood function constructed and then particle swarm optimization algorithm (PSO) tuned utilized estimate parameters. Furthermore, two control charts are which covariance matrix derived based on Fisher information matrix. Simulation studies conducted evaluate detecting...

To evaluate the effect of a specialized multidisciplinary tracheostomy team on outcome patients with severe traumatic brain injury (sTBI).Retrospective study historical controls.Twenty-seven sTBI tracheostomized before implementation approach and 34 followed by team.A regional level 1 tertiary care trauma center, McGill University Health Centre-Montreal General Hospital.Time to decannulation, length stay (LOS), Passy-Muir speaking valve use, extended Glasgow Outcome Scale (GOS-E) scores...

Abstract Nowadays, due to the increasing role of social networks in our daily life, monitoring and forecasting trends have attracted attention many researchers. To best authors' knowledge, literature includes few studies networks. Existing researches focused on analyzing only existence communications between people neglected monitor number such communications. In this paper, first counts are modeled using Poisson regression profiles. Then, 3 Phase I methods, extended T 2 , F a standardized...

This paper presents an integrated model of three interrelated topics including the statistical process monitoring, maintenance scheduling, and production cycle length for imperfect manufacturing systems. The novelty this is to take five features into consideration, including: (1) produced items deteriorate over time, hence, inventory depleted in two ways i.e. responding demand gradually deteriorating products; (2) non-conforming products can be reworked increase cost-saving by eliminating...
