ARTICLE CRITIQUEName:University:Course:Tutor:Date:ARTICLE CRITIQUEBackground and significance of the studyThe background information and the significance of the research question and hypothesis questions are appropriately presented in the introduction part. It is well introduced that the incidence of surgical site infections (SSI) ranges from 0.4% to 8% after a series of heart procedures had been carried out with an overall mean of 1.5%. It is also well stated that endocarditic and mediastinitis after a series of cardiac surgery has serious complications as it increases both short and long-term mobility and mortality rates as well the costs. It is also well stated that it has negative impacts on post operation quality of life. The aim of the study was to scrutinize the impact of the risk factors typically linked with an increased occurrence of these postoperative impediments in the setting of a consistent and randomly allocated antibiotic prophylactic plan. The hypothesis of the research is to examine the impact of risk factors associated with postoperative complications.Research questions and hypothesis of the studyEndocarditis and mediastinitis following cardiac surgical procedures are solemn impediments which have led to an increased short term and long term mobility, mortality rates and costs. They also have a negative impact on postoperative superiority of life. Quite a lot of risk factors including preoperative, intraoperative and postoperative factors have been connected with all these complications in previous reports done on a number of subjects.The research questions are properly stated and appropriate in expressing a relationship between an in depended and a dependent variable. The research questions included the following: 1 Is the duration of antibiotic prophylaxis regimen with the dose of cephazolin tested associated with the impacts on the incidence on postoperative organ or space infections after open heart surgical procedures? 2 What applicable measures can be applied to decrease the rate of these serious complications? 3 What preventive strategies could be applied to help reduce respiratory complications and subsequent SSI?Literature reviewThe research strategy includes an appropriate and adequate number of databases and other...
