Original Question

Review questions for article 6: Özden, D., & Görgülü, R. S. (2015). Effects of open and closed suction systems on the haemodynamic parameters in cardiac surgery patients. Nursing In Critical Care, 20(3), 118-125. doi:10.1111/nicc.12094 1.) What was the purpose of the study? What were the independent and dependent variables? 2.) What level of measurement was the independent variable? 3.) What level of measurement were the dependent variables? 4.) Why does this study matter to evidence based practice? 5.) The authors report several studies they found during their literature review which reported significant differences between utilizing open and closed suction systems, however, these differences were small and clinically irrelevant. What does this statement tell you about the statistical and clinical significance of the studies in question? 6.) This study was conducted in a cardiovascular surgery intensive care unit (CVS-ICU) in Turkey that utilized both open and closed ES. What were the inclusion criteria for the study? 7.) What were the exclusion criteria? 8.) Of the 258 patients admitted during the timeframe of the study they selected 120 from a list of previously designated surgical patients. This is an example of what type of sampling method? 9.) What do you know about the demographic characteristics of the two groups? Were the demographics of the two groups similar? 10.) When were the hemodynamic parameters measured? 11.) How does repeating and comparing the hemodynamic measures on the same subjects over time effect the power of the study? 12.) Look at table 1. Which group had a higher PaO2 level before any intervention at all? Was this a significant difference? 13.) What happened to the average PaO2 level for patients who had open ES from baseline to as soon as the suctioning was terminated? 14.) Look at table 1. What happened to the average PaO2 level for patients who had closed ES from baseline to as soon as the suctioning was terminated? 15.) Look at table 1. The researchers compared the PaO2 levels for patients as soon as the suctioning was terminated using a t-test. What did they report? 16.) Look at table 1. What happens to the average PaO2 level in the open ES group over time? 17.) Look at table 1. What happens to the average PaO2 level in the closed ES group over time?’ 18.) Look at table 1. Were the differences in the average PaO2 level in the two groups significant at any single point of measure? 19.) Look at table 1. The researchers then look at the average PaO2 level within the open ES group at multiple points in time utilizing repeat measure ANOVA. What does this test result indicate? 20.) If the researchers had only compared the groups to each other and not to themselves how could this have potentially impacted the results? 21.) Look at table 1. The researchers then look at the average PaO2 level within the closed ES group at multiple points in time utilizing repeat measure ANOVA. What does this test result indicate? 22.) The researchers report that when they completed a post hoc t-test and evaluated the average PaO2 level for patients who had open ES from baseline to as soon as the suctioning was terminated. Was it significant? 23.) Was the average PaO2 level immediately after ES significantly different from the average PaO2 level at other points in time in both groups? 24.) How do the researchers explain these results? 25.) If the researchers had missed the significance of the drop in the average PaO2 level within the open ES group what type of error would this be?
