Statistical Terms/Databases and Data Sets –

1: Q&A

Data Correct Ans - items, observations, or raw facts Data analytics Correct Ans - The inspection and evaluation of groups of data using statistics. Health Care data Correct Ans - administrative, financial, and clinical data Examples of data items in health care Correct Ans - patient age, sex, marital status, and diagnosis. table Correct Ans - Used to compare characteristics of items. Bar graph Correct Ans - Used to compare categories with each other. line graph Correct Ans - Used to represent data over a period of time pie chart Correct Ans - Used to compare categories with one another in relation to the whole group. Histogram Correct Ans - Used to illustrate a frequency distribution Categories of data Correct Ans - departmental data, financial data, clinical data, administrative (demographic & socioeconomic) data. Information Correct Ans - Data that have been organized to give it context and meaning

Data and information Correct Ans - Used synonymously, but not similar. Data are units of observation and information is organized data for context and meaning. Knowledge Correct Ans - conclusion arrived at by using information to determine a truth. Business intelligence Correct Ans - the application of knowledge to make a decision. Final use of the collection, analysis, interpretation, and presentation of data. Primary purpose of recording data Correct Ans - communication which is necessary to deliver patient care Primary data Correct Ans - The original, firsthand account of the patient's treatment. In healthcare, items that are obtained directly from the patient record and which specifically identify that patient. Secondary data Correct Ans - come from sources other than the original recorder or reporter of the data. Summarized of abstracted items that may or may not be patient identifiable. Types of statistics Correct Ans - descriptive and inferential descriptive stratistics Correct Ans - The analytical activities performed to explain what is and what was. discipline of collecting, interpreting, describing, and presenting data. inferential statistics Correct Ans - study of using mathematical models to predict future events and to draw conclusion about a sample of a population. Population Correct Ans - a complete group of all of the items that are under study. Data that are studied (ex: all of the patients, salaries, doctors, etc..)

Dependent vs independent variables Correct Ans - Independent variables are the suspected cause, while dependent variables are the presumed effect. Qualitative data Correct Ans - 1)groups of categories that can be counted or sorted out but not added together or has no numerical value.

  1. Observations without a numerical value that can be sorted or counted into categories. EX: Likert scales in patient satisfaction surveys (least to most satisfied) Two levels of qualitative data Correct Ans - Nominal level and Ordinal level data Nominal level data Correct Ans - 1)descriptive and have no logical orders.
  2. A type of qualitative data without a mathematical relationship or order among observations.
  3. No numerical value or not measured, but can still be counted. ex: listing of insurance carriers, patient's personal identifier (medical records number), gender, race, and ethnicity. Ordinal level Correct Ans - 1) descriptive and have an inherent natural order
  4. A type of nominal data in which the observations have an ordered value.
  5. no arithmetic relationship among observations ex: patient survey satisfactions satisfaction ranging from least to most satisfied. Qualitative data or... Correct Ans - discrete data dichotomous data binary data categorical data. discrete data Correct Ans - represented by totals for the categories and are represented by whole numbers (47 married patients, 8 widowed, 33 single, and 12 divorced).

Quantitative data Correct Ans - 1) Numeric data (ex: age, weight, height, time,..)

  1. may be used for calculations to further describe their groups (patients, hours per week, or salaries) Qualitative Vs Quantitative data Correct Ans - qualitative data are represented by categories quantitative data are numerical. interval data Correct Ans - 1) have a logical order or ranking, and the the intervals are meaningful, but the concept of a natural zero is missing.
  2. A type of quantitative data without a natural zero, in which the values may be added or subtracted but multiplying and dividing them have no meaning. (ex: interval scale--we are able to add and subtract degrees on the scale, but no meaning with multiplying and dividing) ratio level data Correct Ans - 1) have a logical order or ranking, meaningful, consistent intervals, and include a zero in its order.
  3. A type of quantitative data with a meaningful, natural zero in its order.
  4. Observation may be multiplied or divided to produce meaningful results. (Ex: patient ages, weights, length of stay, billing charges, etc...) Continuous data Correct Ans - 1) represented by numbers that have values in between the whole numbers.
  5. Data on a scale in which numbers have values in between the whole numbers. Ex: temperatures: 37.5; weights: time; salaries: $32,450.81, $49,341.28; ) Differences of data in quantitative data Correct Ans - Interval data and ratio data have numerical value and can have some arithmetic relationships

ORYX for Hospitals (National Hospital Quality Measures) Correct Ans - Maintained by the Joint Commission (TJC) ORYX is the TJC's performance measurement and improvement initiative, which integrates outcomes and other performance measure data into accreditation. Reported to quality check. Uniform Ambulatory Care Data Set (UACDS) Correct Ans - Maintained by National Uniform Claim Committee (NUCC) A set of data to provide uniformity in outpatient settings, collected on a form called the CMS-1500. Uniform Hospital Discharge Data Set (UHDDS) Correct Ans

  • Maintained by National Uniform Billing Committee (NUBC) A set of data elements to provide uniformity in hospital inpatient data, collected on a form called UB- National Cancer Database (NCDB) Correct Ans - Maintained by American College of Surgeons, the Commission on Cancer, and American Cancer Society A nationwide oncology outcomes database for more than 1500 Commission-accredited cancer programs in the United States and Puerto-Rico
