Using Statistical Information
Statistics have become critical to the operation of any medical facility. At Samaritan Medical Center (SMC), we routinely look at data to guide our workflow, staffing and patient satisfaction. One of the most commonly referenced statistical databases used at our facility is Press Ganey. Press Ganey utilizes a mailed survey to a random selection of discharged patients to gauge the quality of care given to a given patient, based on their perception of the hospital visit. (Press Ganey, 2010). The Press Ganey data is generated from a comprehensive patient survey tool, which is divided into multiple areas. This division looks at the patient’s visit by location, provider and individual elements in each area. (Press Ganey, 2010). The resulting data is then presented in different frequency tables. This data encompasses both descriptive and inferential statistics. A descriptive statistic is used to describe a specific set of measurements. (Bennett, 2009). An example of how Press Ganey uses descriptive statistics would be our facility’s quarterly ranking percentile. This information is presented based upon the overall patient satisfaction rating averaged from the responses received from the patient surveys that are returned in the mail. Thus this data is born out of the inferential statistics gathered in the survey. This result is given in a percentage of satisfaction, which is presented every quarter. For example, SMC’s quarterly patient satisfaction rating was 86%. This number is then weighed against other facilities that have the same approximate volume and similar demographics. Based on that comparison, we receive a ranking as compared to these other facilities. Our overall ranking of 86% put SMC in the 60th percentile. Press Ganey also presents data in the form of inferential statistics. Inferential statistics use data gathered from a sample to make...

In choosing caregiver statistics, it is with the intent to familiarize and inform about the staggering numbers of those who are informal or unpaid caregivers on a national level. With baby boomers turning of age, it appears that the need for care givers will increase with those turning of age. “Informal caregiver and family caregiver are terms that refer to unpaid individuals such as family members, friends and neighbors who provide care. These individuals can be primary or secondary care givers, full time or part time, and can live with the person being cared for or live separately”, (Fradkin, & Heath 1992) and (McConnell & Riggs, 1994).
Depending on the definitions and criteria used, the number of informal caregivers in the U.S. has wide latitude in the estimates. The following numbers show the magnitude of informal caregivers.
52 million informal and family caregivers provide care to someone aged 20+ who is ill and disabled. (National Survey of Families and Households, 1998).
29.2 million family caregivers provide personal assistance to adults (aged 18+) with a disability or chronic illness. (Arno, 2002).
34 million adults (16 % of population) provide care to adults 50+ years. (National Alliance for Caregiving and AARP, 2004).
8.9 million caregivers (20% of adult...

Many organizations use statistic to view their overall performance and how they can improve in specific areas of their job. Florence Nightingale, the mother of nursing , utilized statistics by demonstrating and presenting data. Statistics was used by gathering and evaluating data to determine the effectiveness of nursing intervention. For example, central tendency revealed washing hands in between patients decreased the risk for spreading microorganisms for both the health care providers and patients. Statistics determine the results of intervention or treatments and is presented to different types of health conclusions. Statistical applications assess the health outcomes such as determining if an intervention has a good effect of patient’s general health and measures how specific treatments are applicable to certain diseases.
Health care providers practice statistics to measure the outcome of continuous variables, such as temperature, blood pressure or cholesterol, to observe if the values changed after exposure to a treatment. (Zellner, 2008, p. 55). When continuous variables are used, the health care providers are able to compare the “average” values of the variable, such as the mean or median, after the treatment (p. 55). For...

Abstract
For this assignment, I will be looking at the different uses of statisticalinformation used in the healthcare setting. Statistics in healthcare are used in many areas including human resources, employee retention, patient satisfaction, and too many others to name. Hospitals use thisinformation to look at areas that need improvement, to save money, and to improve different workflows. In today’s healthcare environment, it is much easier to look at these statistics with the implementation of the electronic medical record. Statistics that would have taken days or even weeks to obtain can now be filtered through a computer and retrieved in a matter of minutes or seconds.
Statistics Used In the Workplace
Statistics measure a wide variety of items in the workplace. I will focus on those typically used in the emergency department. One statistic used is for stroke patients. It measures the length of time it takes from arrival at a community hospital to the time they are transported to a hospital with a higher level of care. Another statistic that my hospital measures is the door to discharge time. This measures the amount of time it takes for diagnosis, treatment and discharge. Hospitals monitor this closely because insurance companies only allow patients to stay...

As the context of health care is changing due to the pharmaceutical services and technological advances, nurses and other health care professionals need to be prepared to respond in knowledgeable and practical ways. Health information is very often explained in statistical terms for making it concise and understandable. Statistics plays a vitally important role in the research. Statistics help to answer important research questions and it is the answers to such questions that further our understanding of the field and provide for academic study. It is required the researcher to have an understanding of what tools are suitable for a particular research study. It is essential for healthcare professionals to have a basic understanding of basic concepts of statistics as it enables them to read and evaluate reports and other literature and to take independent research investigations by selecting the most appropriate statistical test for their problems (Current, 2012).

The use of statisticalinformation is vital in the healthcare industry. In my current position, we utilize data every day to make it a safe and comfortable environment for every single patient that uses our products. The products we specialize in range from commodity to special devices used in surgery.
Statistics are used in my workplace twofold. There is the healthcare side, as well as the sales aspect of what I do. The company I work for sells products to hospitals, laundries, and other healthcare related facilities. Our products vary from reusable linens to disposable goods, surgical devices, and many more clinical commodity items. I deal directly with customers who have a choice on the products that they buy. They are searching for statistics from me to help them find solutions for their patients. They need to know what makes my product stand out above the competition in the statistical aspects of productivity. They also need to know the price and statistical comparison of other companies to determine if I can give them a better deal. Most of the time, clinicians depend on evidence based practice results from my company to assist them in making a decision.
Descriptive statistics is used throughout my job in so many ways. Descriptive statistics is a set of brief descriptive coefficients that...

...HCS/438 DQ’s
Week 1:
DQ1: What are the differences between descriptive and inferential statistics?
According to Bennett (2009), the biggest difference between descriptive and inferential statistics is that descriptive statistics "deals with describing raw data in the form of graphics and sample of statistics" and inferential statistics "deals with estimating population parameters from sample data." This means that inferential statistics would be an estimate because the data would be estimated from sample data rather than using specific data whereas descriptive statistics would be more accurate. An example of descriptive statistics would be trying to find an average of something such as a G.P.A. or your overall grade in a class. Inferential statics can be used to find the effectiveness of a new medication on a target group.

The four levels of management are:
The nominal level of measurement is the simplest level of variables such as hair color or gender.
Ordinal level of measurement is data with a ranking or ordering scheme such as a star rating used on movies.
Interval level of measurement is when intervals are meaningful but ratios are not such as Fahrenheit temperatures.
Ratio level of measurement is when...
