This paper will define how statistics are used in my place of work. I will provide example of descriptive statistics and inferential statistics that are used in my workplace. I will provide examples of how the four levels of measurements are used in my workplace. I will then explain the advantages of accurate interpretation of information to improve decision making in my workplace. Statistics is important in health care at many different levels such as quality measures, patient satisfaction and revenue. Without statistics, you cannot improve quality measures, patient satisfaction, on manage revenue. Statistics is usually divided into two different categories. Descriptive statistics deals with describing raw data in the form of graphics and sample statistics (Bennett, Briggs, & Triola, 2009). Inferential statistics uses sample data from a population to gather data (Bennett, Briggs, & Triola, 2009). There are many ways descriptive statistics is used in my workplace; one is the use of Press Ganey to evaluate the patient’s experience. Press Ganey is an independent company who mails surveys to patients that was discharged home. Each patient who is selected to be mailed a survey is assigned a code that reflects the unit the patient was discharged from as well as the discharged diagnosis. The survey consists of 20 questions about their impressions of the hospital, the staff, and the physicians. The surveys are than sent back to the company where the data is analyzed and forwarded back to our hospital. The data not only provides the quality of care provided, but also compares our hospital to other hospitals within the Press Ganey database. The data is analyzed by the leadership team and determined what areas need improvement. The drawback of Press Ganey is the amount of returned surveys. An example of inferential statistics used in my workplace is with the stroke population. We are a Primary Stroke Center certified by The Joint Commission. There are standards we need to follow and report to American Heart Association, Get with the Guidelines and The Joint Commission to maintain our certification. The purpose of having a certification is to drive best practice for stroke patients and improve the quality of patient care by reduction variation in clinical processes. There are eight stroke core measures that are abstracted through our stroke quality abstractor. The data is submitted quarterly to The Joint Commission through a secured site. The data is reviewed monthly at with the stroke committee with gap analyzes. Case studies are conducted with any charts that have fallouts with any of the eight reportable standards. Data can be classified by level of measurement, which are nominal, ordinal, interval and ratio. Nominal measurement consists of assigning items to groups or categories but has no meaning other than to label a group. There are pain scales that describe the quality of a symptom, such as a nominal measure of the quality of pain may include categories as aching, dull, sharp, or burning. Ordinal measurement assigns values based on their ranking. An example of ordinal measurement is within the Press Ganey survey. There are four choices to answer the questions, always, sometimes, never. Interval measurements are numerical scales in which intervals have the same interpretation throughout (Bennett, Briggs, and Triola, 2009). An example of interval measurement in our healthcare system is used in the hypothermic protocol for rewarming. There are three categories for rewarming the patient depending on the core body temperature; mild >34ºC; moderate 30ºC - 34ºC; and severe I < 30ºC. Using the interval measurements helps to predict the outcome of the patient. The ratio measurement is an interval scale with the additional property that its zero position indicates the absence of the quantity being measured (Bennett, Briggs, and Triola, 2009). Examples of ratio measurement used in our healthcare system are documentation of height, weight, cardiac output, etc. Height and weight data is abstracted and used in our Bariatric Clinic for research purposes. In health care, it is important to know what to measure and how to manage the numbers. Statistics is important in measuring success or failure. The healthcare organization I work for has established benchmarks and standards of service excellence as this helps to measure the future outcome. Quarterly, we analyze the data of any preventable error, infection control issues, hospital acquired diseases and medication errors. Without this data, we could not improve the quality of care we provide and deliver to our patients. The advantage of accurate interpretation of statistical information in healthcare is to measure our performance outcome, patient outcome and provide continuous quality improvement programs to maximize efficiency.

...Introduction: I work at Cardinal Glennon Children’s hospital. This is a hospital designated to care for children between the ages of 0 through 21 years of age. It is located within the city limits of Saint Louis, Missouri. I am a registered nurse (RN) in the Emergency Department (ED). Our hospital is a 190 inpatient bed hospital (“Cardinal Glennon”, 2015). They also provide specialty care and outpatient services. The ED specifically has a 24 bed unit and is a Level 1 pediatric trauma center. According to our website we see and treat nearly 41,000 children per year in the ED (“Cardinal Glennon”, 2015). It is truly a fascinating place to work and I learn something new every day that I am there. How Statistics are used at my Workplace: At Cardinal Glennon, there are various forms of statistics used. Like many other hospitals, the administration keeps track of numbers for all sorts of reasons. A few examples are as follows; the amount of infections that are related to central lines, how much profit was made each year, how many patients were seen in the ED each day, week, month and year, patient satisfaction scores, handwashing rates of co-workers, amount of blood cultures drawn each month and the amount that were determined contaminated. Those are just a few that matter to nursing but I am sure each individual department has their own forms of statistics they track. After these different sets of data are complied, some form of chart or graph is used to make an impact on the employees...

Alex Ovechkin Case Study

In the first place year Capitals mentor Barry Trotz needs Ovechkin to turn into a more finish player and the initial phase, in the seat manager's eyes, is to recover the Russian objective scorer on the left wing. (Scratch Wass/Associated Press) Alex Ovechkin moved again to left wing by new mentor Barry Trotz As though he knew the inquiry was impending, Alex Ovechkin grinned when asked what his new mentor needs him to take a shot at. "On backcheck?" Ovechkin said from Arlington, Va. An alternate season, an alternate opportunity to discover whether one of the class' most gifted objective scorers can genuinely assist some all the more on resistance. The Washington Capitals opened preparing camp Friday with new mentor Barry Trotz, who says he'll work, as different mentors have before him, to make the three-time group MVP into a more finish player. On the off chance that Day 1 is any evidence, Ovechkin sounds prepared to be a co-agent understudy. "On the off chance that you need to be great," he said, "you need to chip away at everything." Step No. 1, as Trotz had shown at one time, is moving Ovechkin once more to left wing, turning around a seismic movement under past mentor Adam Oates. Ovechkin headed the NHL with 51 objectives keep going season playing generally on the right, however his in addition to short was less 35, and...

Analysis of Newspaper Research Report Results

...Analysis of Newspaper Research Report Results Rolanda Redman HCS/438 July 12, 2015 Sil Di Gregorio Analysis of Newspaper Research Report Results The Chicago Tribune published an article educating readers on the perils of children riding in vehicles of inebriated drivers. The study confirmed that driving under the influence (DUI) related deaths among children reveals the children were riding in the vehicle of the inebriated driver. This recklessness needs to stop before another child pays the consequences of an irresponsible individual. Gregory & Ziezulewicz, (2014) report from 2001 to 2010, 2,344 children under age 15 were killed in crashes involving at least one alcohol-impaired driver. Illinois recorded 42 of those deaths during that time, holds one of the lower rates of child passengers killed in crashes involving impaired drivers. South Dakota had the highest rate. New Jersey, New York and Massachusetts registered the lowest rates. The report reveals of those 2,344 deaths, 1,515 of the children were with impaired drivers. Most of the drivers survived the crashes, while the unrestrained children died. In this writer’s opinion, this article used descriptive statistics to get the point across to the readers. This writer’s thinks the authors of the article are trying to use these statistics as a tragic example of the recklessness of the driver. The authors cited their references but the reader would have to do research to see if the numbers are actually...

...Analysis of Research Report Paper HCS/438 Analysis of Research Report Paper Spousal homicide is a very serious issue facing society today. Rising as one of the most predominate reasons for murder, spousal homicide is an issue with more statistics available than most homicide related deaths. In the study, “Spousal Homicide Risk and Endangerment”, multiple statistical procedures are used to identify such things as rate between genders, rate in area, etc. For one, the study mentions a collection of data on perpetrators of spousal homicide in Sweden over a nine year period between 1990 and 1999, compared to pure homicide in Sweden in the same time frame. By using this statistical gather procedure, they were able to determine that homicide in Sweden was four times more likely among married people as compared to unmarried people. What’s more, they found that 80% of the perpetrators in the spousal homicide cases had some type of mental disorder, clearly indicative of possible violence against their partner, and may not have been caught as a statistic if not for the collection of data for spousal homicide. Another procedure used in this study was a gender ratio statistic. What they found was that out of 276 spousal homicides between 1991 and 2010, 234 of those were committed by a man, as opposed to 42 by the female. This was a study in Quebec, they also did a companion statistic that found only 28% of the females who murdered their husbands had been previously abused in the...

Statistical Analysis

...Statistical Information Paper HCS 438 July 17, 2011 Monica Vargas Statistical Information Paper Statistics are used in many different ways in my workplace. The use of statistics is for the improvement of quality care and safety. Statistics are also used to measure employee compliance in regards to hand washing and proper use of policies and procedures. We also use charts and graphs to show infection rates, skin integrity, falls within the facility, budget concerns, and many more. These graphs help hospital personal improve care and safety to provide quality care to all patients. Graphs can also be used to measure patient and employee satisfaction. Descriptive statistics are used to describe the basic features of the data in a study and do not involve generalizing the data that has been collected. They provide simple summaries about the sample and the measures. Together with simple graphics analysis, they form the basis of virtually every quantitative analysis of data (Trochim, 2006). An example of descriptive statistics used at my workplace can be the number of patients that are admitted into the hospital on a Monday versus a patient admitted on any other day of the week. This information can also be broken down into more descriptive categories such as how many patient were men, women , children, what is their diagnosis, why were they admitted, and so on and so forth. We use inferential statistics to make judgments of the probability that an observed difference...

The Los Angeles Times newspaper published recent research on the obesity rates of Americans. Whereas, certain group’s weight continues to increase, American’s weight appears to be leveling off (Roan, 2012). The article in Los Angeles Times newspaper,, “Obesity rates in the U.S. appear to be finally leveling off,” does not give the mean, mode, or median. However, it does report the sample size of people surveyed from the National Health and Nutrition Examination Survey done from 2009 to 2010. Seventy million people in America are obese with a body mass index (BMI) of 30 and higher. This statistical data is similar to years 2005 to 2006. Furthermore, children and teenagers weights in 2007 to 2008 have not increased or decreased according to the Journal of the American Medical Association. Percentages of decrease or increase, according to the Los Angeles Times, are reported by the Centers for Disease Control and Prevention (CDC), the Journal of the American Medical Association, and the National Health and Nutrition Examination Survey along with other statistical data collected for this article (Roan, 2012).

Statistical Uses

...Use of Statistical Information HCS/438 August 6, 2012 Use of Statistical Information Statistics is defined as “the science of collecting, organizing, and interpreting data” (Bennett, Briggs, & Triola, 2009). For most patients and their families, the process of healthcare appears simple. People with illnesses are admitted into a hospital facility and a specific course of treatment is identified and the care is carried out by a team of physicians, nurses, and social workers. What is not noticed is a specialized resource team aimed at keeping all patients safe throughout the course of their hospitalization. This paper will identify how statistics are utilized in the infection prevention setting, identify one example of descriptive statistics, identify one example of inferential statistics, explain data at each of the four levels of measurement and describe the advantages of accurate interpretation of statistical information to improve decision making in the workplace. How Are Statistics Used in Your Workplace There are many uses for statistical application in the field of infection prevention and control. The purpose of infection prevention and control is to put into place policies and procedures that minimize the spread of infections, especially in the hospital setting.
