Summary
Evidence Based Approach to Ventilator Acquired Pneumonia Name of Student Institution Though medical interventions aim at restoration of patient’s well-being, some medical procedures may pose as demerits by acting as source infections. Ventilator acquired pneumonia (VAP) is one of those infections (Chastre & Fagon, 2008)…

Chastre, J. & Fagon, Y. (2008). Ventilator-associated pneumonia. American Journal of Respiratory Critical Care, 165 (7), 867-903. The effective duration of antibiotic use is not clear. The research done by Chastre & Fagon aimed at identifying the relative efficacy of an eight day regimen compared to a fifteen day regimen. Antibiotic chemotherapy is crucial in the management of VAP since it usually caused by bacteria. According to Chastre & Fagon, a short duration regimen would have the benefit of decreased development of drug resistance, but the patients would have lower survival rates (2008). This inference was made due to the observation that more people died after the eight day therapy but, the occurrence of drug resistance incase of relapse was lower in these people. This document will used as an inference as it elaborates on the relationship on chemotherapy and decreased mortality of VAN.

This journal is based on research carried out in Canadian hospitals and utilised one thousand and fourteen sick people admitted in these hospitals. This large sample size coupled with the prospective cohort method of research also used was ideal in the coming up of reliable results to establish the predisposing factors. According to Cook et al., the key predisposing factor was the duration of time spent at the intensive care unit (1998). This was because most of the patients who acquired VAP had stayed in this specialised care area for more than five days. Other associated factors include body injury, burns, respiratory disease, cardiovascular disease, neurologic disease, paralysis and regurgitation of gastric contents into the airways. Iregui, M., Ward, S., Sherman, G., Fraser, J.V., & Kollef, M.H. (2002). Clinical importance of delays in the initiation of appropriate antibiotic treatment for ventilator-associated pneumonia. Chest. 122 (1), 262-268. In addition to the duration of antibiotic use, another important parameter that influences the outcome of VAP is the time taken since diagnosis up to the time when antibiotic therapy is initiated in the patient. Iregui et al. cite that a delay in prescription is the most common reason that leads to an increased time interval (2002). In their research, Iregui et al concluded that the delay was associated with increased morbidity and mortality of patients (2002). Therefore, it is necessary to undertake a swift diagnosis and prescription processes for these patients. Fagon.

Ventilator associated pneumonia

...? VAP Bundle and Implementation Ventilator Associated Pneumonia or VAP is one of the leading causes of mortality in patients who are ventilated. It is also the leading cause of death among hospital acquired infections. There is some evidence that implementation of certain interventions, grouped under VAP bundle, decreases the incidence of VAP from 20 per 1,000 ventilator days to 5 per 1,000 ventilator days (Safer Healthcare Now, 2011). The VAP bundle includes four components of care and they are: 1. Elevation of the head of the bed of the patient This is the most integral part of VAP bundle and has been strongly...

Ventilator Acquired Pneumonia

...suctioning of the secretions from epiglottis; use of tracheostomy and endotracheal tubes that have an extra subglottic port that can be used to clear the pooled secretions; specially designed endotracheal tubes that do not allow pooling of secretions; and Tracheal Suctioning systems (TSS) (Zack, 2002). Conclusion Ventilator associated Pneumonia is among the hospital acquired infections that have an increased mortality rate. This is evident among the patients in ICU. VAP should be suspected in patients on mechanical ventilation whose health is deteriorating. The methods of diagnosis include clinical approach, radiographic findings, and...

Ventilator Acquired Pneumonia: Literature Review and Theory Application

.../days. After the multipronged approach, the rate dropped to approximately 0.5 cases per 1,000 ventilator/days (Arroliga, 2009). This study objectifies the imperativeness of a multidisciplinary approach in tackling VAP. For effective management and preventive strategy, one needs to approach the disease from several angles. Another study was conducted by Keeley in 2007 sought to identify whether the occurrence of ventilator acquired pneumonia can be reduced by elevating the head of the patient to 45 degrees. This study was carried out in the Royal Sussex County Hospital in the Critical Care department. The study utilized 30...

...? Middle Range Theory Application Middle Range Theory Application An informed application of the provisions of the caring theory developed by Kristen M. Swanson could help in reducing and mitigating the impacts of ventilator-associated pneumonia (VAP). The theory supplies the structural and theoretical approaches that might help in combating the nosocomial infection, which remains one of the deadliest pneumonia complications that affect patients who are routinely subjected to ventilators while at the hospital (Acton, 2011). Multiple studies have established that it is possible to reduce the impacts of this disease through a proper administration of...

Polices and guidelines There are several polices set according to the hospitals. However, the polices in each hospital are common. For example, in the hospitals the use of an ongoing program on the infection and preventive control on the patients undergoing mechanical ventilation should be adopted. Information such as the location of the local and epidemiological evidence based strategy needs evaluation and it should therefore include the information on the evidence-based strategies for the control of the...

Evidence Based Practice: Use of the ventilator bundle to prevent ventilator associated pneumonia

...Evidence Based Practice: Use of the Ventilator Bundle to Prevent Ventilator-associated Pneumonia Introduction Mechanical ventilation is commonly usedin the intensive care setting to artificially ventilate persons who are unable to breathe spontaneously at all or are unable to provide themselves with adequate spontaneous ventilation to guarantee satisfactory gas exchange (Boles et al., 2007). This becomes more relevant in a district hospital working in the capacity of a critical care nurse, where supports from the specialist care professionals are less available, and where the nurses in the critical care...

Critique of Systemic Research Review (SRR): Preventing Ventilator Acquired Pneumonia in The Acute Care Setting

...Preventing Ventilator Acquired Pneumonia in the Acute Care Setting Systematic Research Review Introduction Pneumonia refers to inflammation that occurs at the lungs due to irritation by chemical substance, bacteria, virus, fungi or an aspirate. Pneumonia can either be community acquired or nosocomial in nature. In the hospital setting, patients can be able to get pneumonia from nosocomial infections, mechanical ventilators or during aspirations in anesthesia. Quite a number of studies have been on going in regard to ventilator acquired pneumonia which is...

..., condition and influences affecting and surrounding the development of an individual with particular consideration of the interrelationship with the earth resources, challenges and their residual stimuli. The theory had two subsystems approach (Datta, 2013). First, the cognator, which involves fours channels of cognitive emotions. The four included judgment, emotion, learning, information and perpetual information. Basing the theory to the study of intervention of the ventilator-associated pneumonia, this may suggest that individual who at one point in their lifetime was exposed to the bacteria causing VAP; they can develop resistive character to the infection or the...

Reducing the Risk of Ventilator-acquired Pneumonia

...of the sample size that was used could be able to be overcome through prolonging the length of the study to include a large sample or through making the study multicenter. As described by Hubmayr (2002), the duration of mechanical ventilation of antibiotic exposure before the onset of VAP are considered some of the most important factors in the microbiology, incidence, and severity. Conclusion The findings show that the study did not provide sufficient evidence to support changing the clinical practice. The trend that is obtained from the research shows that a reduction in the incidence of VAP through the increase of angle of head evaluation from 25 to 45. The fact however needs further...
