Chapter 1 Statistical Terminology and Health Care Data Statistics Collection, organization, summarizing, and analysis of numerical data Statistical reports often refer to the “number of” an event Analysis of statistical data is done to draw reasonable decisions and conclusions about the data Health care statistics, employment statistics, vital statistics School of Health Science

Chapter 1 Statistical Terminology and Health Care Data School of Health Science Data are used to derive information Data are facts in numerical form Data are collected on: -Inpatients, outpatients, emergency department patients, surgical patients, employees, encounters, and financials

Chapter 1 Statistical Terminology and Health Care Data Demographic data Used in: In planning and disease control By hospital administrators to analyze the health care service needs of their communities and service areas To identify the geographic density of a given area such as a county, city, suburb School of Health Science

Chapter 1 Statistical Terminology and Health Care Data Who may request data? Administration and Governing Board Medical staff Treatment facilities Outside agencies and organizations Insurers/payers Researchers Government agencies School of Health Science

Chapter 1 Statistical Terminology and Health Care Data Data Uses Used in decision making for management and patient care decisions Patient care decisions include: Hospital-acquired infections Medication errors Diagnosis-specific length of stay Statistical reports: Example: Indices Birth Death Disease Research: Treatment protocols School of Health Science

Chapter 1 Statistical Terminology and Health Care Data Users of Data Internal users External users of data Sources of Data Primary data Secondary data School of Health Science

Chapter 1 Statistical Terminology and Health Care Data Role of Heath Information Management (HIM) Professionals collect, preserve, and present data in health care facilities HIM practitioners require a basic understanding of statistics HIM practitioners can assure accuracy of data in the data collection process School of Health Science

Chapter 1 Statistical Terminology and Health Care Data Statistical Terms Population Sample Constant Variable Qualitative Quantitative Nominal Data Ordinal Data Descriptive statistics Inferential statistics Morbidity data Mortality School of Health Science

Chapter 2 Health Care Overview and Patient Data Collection Terms Encounter Occasion of service Visit Health Care Settings Inpatient (IP) Outpatient (OP) Health Care Providers Hospitals Long term care facilities Skilled Nursing (SNF) Residential Care (RCF) Specialized facilities School of Health Science

Chapter 2 Health Care Overview and Patient Data Collection Two ways to collect data include: Concurrent During hospitalization Retrospective Following discharge Primary source Medical record including physician notes, lab reports, surgical reports Secondary source Abstracts, lists, indexes, registries Indexes Computer generated list to locate information Master Patient Disease Registries Repository of abstracted data Cancer/tumor registry Trauma registry School of Health Science

Chapter 3 Mathematical Review An amount less than one Digits to right of decimal point are decimal digits Decimal point separates the fraction of the whole number from the whole number itself A percentage is the number of times something happens out of every one hundred times It tells us how many hundredths are of interest A percentage is a specific rate or ratio followed by the percent sign (%) A percentage is a fraction expressed in hundredths Example: ¾ = 0.75 = 75% School of Health Science

Chapter 3 Mathematical Review A fraction is a Fragment of a number Part of a whole Written as ¾ Numerator Number above the line Denominator Number below the line Quotient Result of dividing denominator into the numerator Example: to determine the quotient using the fraction ¾ divide denominator into the numerator 3 divided by 4 is.75 School of Health Science

Chapter 3 Mathematical Review An average is the value obtained by dividing the sum of a set of numbers by the number of values An average is also referred to as the arithmetic mean to distinguish it from the median and mode The average is the sum of all scores divided by the number of all values involved Rounding approximates a total or final number Rounding data is done to arrive at a usable number Numbers are rounded to the nearest 10, 100, etc. Rounding to the nearest ten means to round the number to the nearest multiple of ten or 10, 20, 30, 40, etc. School of Health Science

Chapter 3 Mathematical Review Converting a fraction to percentage Divide the numerator by the denominator and multiply by 100 Converting a ratio to percentage: Divide the fraction Multiply the quotient by 100 Converting Decimal to Percentage Move the decimal point two places to the right of the decimal point and add the percent sign Or multiply the decimal by 100 Converting Percentage to Decimal Cross out the percent sign and move the decimal point two places to the left of the decimal point Example: 65% =.65 If the percentage is only one digit: Place a 0 in front of it and place the decimal point in front of the 0 Example: 5% =.05; 105% = 1.05 School of Health Science

Chapter 3 Mathematical Review Converting Percentage to Fraction Cross out the percent sign and place the number in the numerator Place 100 in the denominator Example: 45% converted to a fraction Replace the percent sign with 100 Write as a fraction = 45/100 Reduce to the lowest fraction = 9/20 45 and 100 can both be divided by 5 Therefore, the lowest fraction is 9/20 School of Health Science
