NR 716 Week 5 Discussion; Analyzing Descriptive Statistics...

Perform the following calculations: Based on the data set provided, calculate the average percentage of patients with uncontrolled diabetes (HbA1c>7) both pre-implementation and post-implementation. Pre-intervention: 9 =90 % 10 Post-intervention 5 =50 % 10 Next, calculate the mean pre-implementation and post-implementation HbA1c values for patients involved in this practice change project. Pre-intervention: ∑ Pre intervention Outcomes n 7.4 +7.8+7.1+6.8+7.4+ 7.8+7.8+8.2+7.5+11.8 10 79.6 =7.96 10 Mean is 7.96 Post-intervention ∑ Post intervention Outcomes n 6.4 +6.7+6.7 +6.8+6.9+7.1+7.4+ 7.7+8+11.3 10 75 =7.5 10 Mean is 7.5 Now calculate the pre-implementation and post-implementation median score of HbA1c levels. Pre-implementation: 6.8, 7.1, 7.4, 7.4, 7.5, 7.8, 7.8, 8.2, 11.8 Median= 7.5+7.8 =7.65 2 Median is 7.65 Post-implementation: 6.4, 6.7, 6.7, 6.8, 6.9, 7.1, 7.4, 7.7, 8, 11.3 Median= 6.9+7.1 =7 2 Median is 7 Next, calculate the pre-implementation and post-implementation standard deviation of HbA1c levels of patients involved in the practice change project. The standard deviation will determine the spread of increase or decrease in HbA1c levels. Pre-implementation n s2=∑( xi−x̄ )12 i=1 s2=(7.4−7.96) 2 + (7.8−7.96 ) 2 + (7.1−7.96 ) 2 + (6.8−7.96 ) 2 + (7.4−7.96) 2+ (7.8−7.96 ) 2 + (7.8−7.96 ) 2 + (8.2−7.96 ) 2 + (7.5−7.96 ) 2 + (11.8−7.96) 2 s2= 17.8144 10 s2=1.78144 1757679175178 s=√2 s2 1757679138227 s=√2 1.78144 Standard deviation =1.3347 Post-implementation n s2=∑( xi−x̄ )12 i=1 s2= (6.9−7.5) 2 + (7.1−7.5) 2 + (6.7−7.5) 2 + (6.4−7.5) 2 + (6.8−7.5 ) 2 + (7.7−7.5) 2 + (7.4−7.5) 2 + (8−7.5) 2 + (6.7−7.5) 2 + (11.3−7.5) 2 s2= 18.4 10 s2=1.84 1300480303552 s=√2 s2 s=√2 1.84 1301750-461951Standard deviation =1.356 Finally, calculate the pre-implementation and post-implementation range of HbA1c levels. If no outliers exist, the range will determine how close together HbA1c levels are in the patients involved. Preintervention range=11.8−6.8=5 Postintervention range=11.3−6.4=4.9 Based on your analysis of the descriptive statistics, what determinations related to the mean HbA1c levels following implementation of the evidence-based intervention can be made? Based on the analysis of HbA1c levels, it can be noted that the results are not in range for the pre and post intervention. There are outliers in the patient number 10
