Critical analysis of research Evidence Free Essay Example, 1250 words

Validity: What has been found to be the major strength of this study was that it made use of five research tools in an effort to gather the data needed. The tools were composed of observation, surveys, and health assessments (Abbott et al. , 2006). Even if three among the five research tools were made by VAP group created, they can be considered valid as it went through face validity when it was administered to a pilot group. Unfortunately the reliability score of the instruments were not revealed. Statistical Analysis: The statistical tools used included a t-test and a multivariate analysis of covariance. Applicability to the Setting: As a whole, this study has not really established whether the adoption of the clinical practice guidelines can make a significant impact in reducing the incidence of VAP. Research Study Title 2: Supine Body Position As A Risk Factor For Nosocomial Pneumonia In Mechanically Ventilated Patients: A Randomised Trial. Summary: This study was made to find ou t if a semi-recumbent position can help decrease the frequency of nosocomial pneumonia in patients (Drakulovic et al. ,1999). The subjects were divided into two groups with one group having a semi-recumbent body position and the other a supine stance. It was found that the group positioned in a semi-recumbent way had less tendency to develop nosocomial pneumonia in comparison to those positioned in a supine set up. Problem Statement and Research Question: This study was very focused on only one question and that was to find out how frequent nosocomial pneumonia develops when patients have either a supine or semi-recumbent body position (Drakulovic et al. ,1999).

There were only four researches incorporated in the study and one is not directly related to the case of nosocomial pneumonia. Validity: The patients were given equal and regular amounts of treatment to ensure that the likelihood of developing the pneumonia can be prevented (Drakulovic et al. ,1999). The subjects were randomly assigned to the two groups by means of a computer generated list. These efforts could decrease the possibility of intervening factors from affecting study results. No reliability measure was mentioned. Statistical Analysis: The tools used in the study included an interim analysis, a univariate analyses, Fihser’s exact test, and Student’s t test (Drakulovic et al. ,1999). In answer to the research question, the interim analysis showed that there is a significant decrease in the development of pneumonia in the semi-recumbent group at p=0.003.
