Look at the following research article to see how the statistical techniques you have already learned are used in practice: Edwards, A., Sitanggang, N., Wolff, K., Role, J., Cardona, T., Sanchez, M., & Radovich, P. (2021). Pressure injury prevention in patients with prolonged ED stays prior to admission. American Journal of Nursing , 121 (2), 46– 52. 1. What was the purpose of this study? 2. Why does this matter? 3. What are the mean and median costs per hospital-acquired pressure injury (HAPI)? 4. Because the mean and median are not the same, what does this tell you about the distribution? 5. In 2015, a nurse-led evidence-based practice (EBP) team detected an increase in HAPIs and set out to assess the situation. They conducted a root-cause analysis and a retrospective chart review. What was the incidence rate (new cases) of HAPIs from May to August 2015 before the intervention? 6. Was the correlation between HAPI incidence and emergency department (ED) boarding time significant in the baseline analysis? 7. What was the sample in this study? 8. After finding a positive correlation between HAPI incidence and ED boarding time in their initial sample (May to August 2015), the team developed an intervention consisting of improving supplies in the ED, staff education, and the use of standardized skin assessment and prevention care for high-risk patients while in the ED. They measured outcomes from June to August 2016 for this intervention group and compared the results to the 2015 group. What happened to the incidence of HAPIs? 9. Then they measured the outcome variables again in October 2016– January 2017 after the intervention to see if there was any sustained change. What happened? 10. They compared the average boarding time in the baseline group, the intervention group, and the postintervention group with an analysis of variance (ANOVA). Why didn’t they use repeated-measures ANOVA? 11. You are a nurse manager in an acute medical unit. If you feel these results are clinically significant, what might you decide to do in your hospital?
