Visual Data Displays and Uses in Decision Making

Visual Data Displays and Uses in Decision devising Ronya Bentz, Lasondra Defreeze, Terri Dougherty, Grace Zhao HCS/438 September 24, 2012 Gerald Rintals Visual Data Displays and Uses in Decision devising Studying the beatniks of commutation disposition will help to verify if these measures of central tendency for the given data are correct. The information will supporter in predicting specific health issues and interventions needed to improve health care. The measure of version produces a conclusion through the Tele-care monitoring agreement.The types of central tendency conducted in this guinea pig were the mean and median(a). The description of data in this try out usances the five-number summary. Variables were also used to predict key medical examination events and interventions, based on significance. According to Biddiss, Brownsell, Hawley (2009), the data analysis was conducted using statistical software and logistical regression was used to predict the occurren ce of key medical events/interventions taken from health care logs of health-care workers. Biddiss, Brownsell, Hawley 2009s articles explain examples in the text are as lives The 45 patients studied a tally of 8576 alerts were gene set outd. A total of 171 medical events which included the mean number of medical events for the year which was 3. 5, the median 2, and the quartile ranged between 1- 4. The mean medium of key alerts per year was 49, with a median of 49, and an interquartile range of 47-51. The average percentage of total alerts that were medical events was 6. 4% with a median of 4 and an interquartile range of 1. 4-8 (p. 227-228).Because the focus of the mull determined the average need for medical intervention in congestive inwardness failure, the use of the measure of central tendency is correct in this study. According to Bennett, Briggs, & Thiola, (2009), variation is a measure of how much the data values are interpenetrate out. A distribution in which most da ta are clump together has a low variation. (p. 16). In the article, predicting need for intervention in individuals with congestive heart failure using a home-based Tele-care monitoring system for 18 months (Biddiss, Brownsell, & Hawley, 2009, p. 9) the authors monitored 45 elderly individuals with congestive heart failure who interposeed effortless information, based of individual symptoms and health status. There are 14 variables to enter and generate the alert system. Systolic furrow pressure 2541 Heart rate 1822 Day duration shortness of breath 803 Need for extra pillows 576 Night time shortness of breath 480 Cough 441 Weight gain 422 Bloated stomach 387 dizziness 339 Medication adherence 327 Swollen ankles 248 Angina 191 Anxiety 10 pissing excretion Eight total alerts 8576 Biddiss, Brownsell, & Hawley, 2009, p. 29). As the data describes, the systolic blood pressure most triggered the alert system. It produced nearly 30% of the total alerts and the heart rate almost 9%. Average of alerts for 14 characteristics 612 Median 405 dissemination is pay off skewed because the values are more spread to the right side. The graphing of a bell curve is the representation of the standard normal distribution. likewise the table shows the mean value is zero and the standard deviation is ace (Bennett, Briggs, & Triola, 2009).In Figure 2 of the study, the values are not depicted by normal distribution as they deviate greatly from the mean. This shows there is no symmetry in the values represented and displays too many variables. Because the study is measuring various variables not necessarily related to one another, it would follow that standard normal distribution would not apply in this study. The results of this study show factors of individuals who took part reported different symptoms and clinicians monitoring these concerns had determined if medical intervention was necessary.Heart rate, blood pressure, and weight were also considered and compared with t he data reported by the participants. Because the study relied heavily on self-reporting by the participants, many of the variables were subject to embellishment. The clinical data supports reports of declining health, but in some cases may not tally with information reported. The conclusions of the study are favorable, as increased monitoring of patients with degenerative heart failure may result in occasional interventions that are not neccessary.This study provides an improvement in the knowledge of the patients condition and reaction to treatment.
