Introduction: What is a systematic review?
A systematic review is a paper that summarizes the results of available studies and provides information on the reliability of results and evidence by working to delimit bias (Schlosser, R., 2006). It may or may not make judgment on the value of this information for health care practice. To have a better understanding of what a systematic review is, I decided to look more closely at one myself. After considering my recent experience in the nursing lab with practicing and reviewing cardiopulmonary resuscitation (CPR) and considering the importance of knowing how to do this accurately, I decided to use this as my search term. The systematic review I found to be most interesting was entitled, “Cardiopulmonary …show more content…
According to the American Heart Association (2015), each year over 320,000 out-of-hospital cardiac arrests (OHCA) occur and as a result are one of the leading causes of death in the United States. With the frequent occurrence of such a life-threatening event, it is essential to understand the proper way to react. Cardiac arrests can be separated into three groups; ventricular fibrillation/tachycardia (VF/ VT), pulseless electrical activity (PEA), and asystole. The most common arrhythmia is VF or VT; during this event CPR provides a means to circulate the blood while defibrillation helps to restore rhythm (Huang, He, Yang, Liu, & Jones, 2014). Early defibrillation is associated with higher survival rates (Valenzuela, Roe, Nichol, Clark, Spaite, & Hardman, 2000). However, some hypothesize that CPR before defibrillation creates a more conductive environment (Huang et al., 2014). Understanding the priority of whether CPR or defibrillation needs to occur first is essential to improving survival rates. The overall question of this systematic review seeks to determine this order by asking; whether or not CPR plus defibrillation or immediate defibrillation resulted in better patient outcomes in OHCA. This question was addressed by examining whether 1 to 3 minutes of CPR performed by paramedics resulted in better survival rates and neurological outcomes compared to immediate defibrillation upon paramedic

    Targeted Temperature Management Case Study

    The goal of this trail is to give a higher life expectancy of a patient who has an out of hospital cardiac arrest with loss of consciousness and see if putting the body into a very low stage of hypothermia allows for a higher expectancy of survival both in cardiac and neurological function. The hypothesis is that if the patient is put into the 28°C category, then that means that the body has to be in the state hypothermia longer; allowing more time for the body to rest and recover uninterrupted. This way body can focus all of its energy on repairing the brain signals and recover from the heart attack than having to worry about body temperature regulation, breathing and about the patient moving to name a few. It gives the doctors and researches a longer time to observe and work with the body, to find what medications and care is more effective for the…

    EGT1 Task 3

    According to Grove, Burns, and Gray (2015), systematic review and meta-analysis are considered to have the strongest evidence because the researchers utilize explicit methods when conducting systematic reviews, which assist to eliminate bias to facilitate production of reliable findings. The meta-analysis and evidence-based guideline has strong evidence and are ranked on the topic together with systematic reviews. The randomized control trial is the next in the pyramid, followed by quasi-experimental study, non-experimental (such as correlation and cohort studies), a systematic review of the qualitative study, descriptive study and expert opinion in that order. The randomized control trials are experiments used to test the efficiency of healthcare interventions by assigning individual control or experimental groups. Controlled clinical trials are testing treatment used for evaluating the outcome of a studied intervention where a bias-free method is used to assign patients to the treatment…

    Again the carer was unable to inform us if this was the case. We did ascertain that the patient was not suffering a terminal illness where death was imminent & unavoidable (JRCALC, 2013). My colleagues and I assessed the situation and concluded attempting resuscitation was in order (Institute of Health and Care Development (IHCD), 2003). We moved the patient from the bed to floor and promptly began chest compressions whilst attaching the defibrillator pads and inserting an airway.…

    Primary Research And Evidence Based Practice Essay

    Evidence based practice (EBP) involves the integration and analysis of primary research findings to make decisions on best practice for effective patient care (Melnyk & Fineout-Overholt, 2015; Polit & Beck, 2012). These forms of research complement each other as well. Primary research is the building block for EBP inquiries. EBP research involves the analysis of multiple primary research studies to make decisions about the most effective, highest quality patient care strategies. Numerous primary studies must be completed to generate enough evidence to promote change in practice to affect patient care and contribute to a culture of evidence based practice…

    Evidence Based Practice Process: A Case Study

    Mara, Your posting, does a fantastic job in breaking down steps zero and step one of evidence based practice process. Similarly, when appropriate steps are not taken or particular steps are skipped in an operational process failure often occurs. A clinical example of this is when a patient is about to be discharged from a hospital after breaking their right ankle with pins placed, the patient commonly asks questions evaluating what to expect at home with healing (step zero). Then once the patient is in their own environment, events and situations become true test (establishing keywords). The patient really wants to cut the lawn but recall’s discharge restricts were given, such as no strenuous activity for example, cutting the lawn (step 1)…

    Pseudo-PEA Essay

    While no universal definition exists, PEA is often deemed as being either “true-PEA” or “pseudo-PEA”; a distinction that is based on the strength of the myocardial contraction. Both pseudo- and true-PEA involve appropriately organized cardiac electrical activity. The term “pseudo” implicates the production of weak myocardial contraction that is insufficient in producing a palpable pulse, whereas “true” describes an absence of myocardial contraction altogether (2). During arrest, pseudo-PEA often precedes true-PEA, but the two cannot be differentiated without direct visualization of mechanical ventricular activity (MVA) on ultrasound (3). Patients with pseudo-PEA potentially have better resuscitation outcomes than patients with true-PEA due…

    Systematic Review Paper

    The authors of the article, “Systematic Review of Apraxia Treatments to Improve Occupational Performance Outcomes”, set out to evaluate serval of the currently published treatments for apraxia, in order to find which type of intervention is most effective on a patient’s occupational skills. The need for such a review stems from the fact that many apraxia studies lack a focus on occupational performance, such as ADL’s and IADL’s. After setting up the criteria for selecting the articles to be include in the review, the authors used the FAME (feasibility, appropriateness, meaningfulness, and effectiveness) rating system to determine which type of intervention proved to be best for the use in occupational therapy. Eight studies were included and can be grouped into three different treatment approaches: errorless learning approach, gesture training, and strategy training. In was concluded that task-specific strategy training is the best treatment for patients suffering from apraxia.…

    Evidence Based Practice Paper

    Prior to joining my present healthcare organization, I labored with one of the largest public hospital in Atlanta for five years, while working at the surgical intensive care unit; we had a critical ill, unstable patient with intra-aortic balloon pump unfortunately developed a stage II pressure ulcer due to the inability to mobilize her. The patient was treated with arrays of skin care to heal the wound to no avail, finally underwent surgical debridement and grafts, which made me wonder what could have been done to avert the added agony the patient encountered, this is how evidence-based practice came into existence for me, to ensure this agonizing event do not occur again. My inquisitive took me to a mentor and the clinical nurse specialist on the medical intensive unit; she was an advocate for EBP and with further investigation on arrays of research analysis and incorporating the leadership team and the wound care department. This event led to the development of best practice, guideline and policies created for skin and wound care that immensely have profited arrays of…

    Evidence Based Study Examples

    An example of the limitation is deep brain stimulation for patients with Parkinson’s resulting a lack of controlled data, mismatch evidence, insufficient medication effect in the clinical practice. Another instance of the limitation in the EBM are the patients with non-motor symptoms of PD. Some areas such as constipation, anxiety, fatigue, insomnia, sexual dysfunction urinary incontinence have not been thoroughly discussed in the research for symptoms of PD patients which can be considered as an evidence gap for standard of care therapy. Pharmacologic treatments such as amantadine, dopamine agonist, anticholinergics, levodopa formulations have lacking evidence with regards to their effectiveness for the delay progression or preventing the progress of PD. Furthermore, some medications serve as a symptomatic monotherapy such as amantadine and anticholinergics are considered as probable or likely effective, dopamine agonist like cabergoline and ropinrole are updated to be effective as a symptomatic…
