  1. Exam 3
    10/16/12
  2. How is statistics used in the hospital and health care facilities?

    Internal & external uses...
    • Internally:
    • as a management tool for decision making
    • personnel and staffing
    • budgeting

    • Externally:
    • accrediting
    • state licensure boards
    • health planning commissions
    • physician training porgrams
    • nursing and allied health training porgrams
  3. types of data
    - nominal 
    • Also called categorial, qualitative or named data
    • Include numeric values assign to catergories
    • Example: Male =0 Female=1
  4. types of data
    - ordinal
    Represent rankings according to some criterion

    • Example: Severity of illness
    • 0=no risk illness
    • 1=low risk
    • 2=moderate risk
    • 3=high risk
    • 4=severe risk
  5. types of data
    - discrete
    Numeric values in which the number has meaning. (usually a whole number)

    Example: number of admissions by residence (city, suburbs, rural)
  6. types of data
    - continuous
    Continous data assumes an infinite number of possible values

    Example: charges(cost) or weight
  7. Methods of presentations: (differences & similarities) 
    - frequency distribution 
                           
    • Allows nominal, ordinal, discrete, and continous data to be grouped into specific categories and the total number of observations in each category to be displayed.
    • Percentage represent the relative frequency
  8. Methods of presentations: (differences & similarities) 
    - bar graph
    • used to compare different things at one time or one thing over a period of time i.e the frequency of a variable
    • Horizontal (x) shows discrete category
    • Vertical (y) shows the frequency 
  9. methods of presentations: (differences & similarities) 
    - histograph
    • Used to represent frequency distributive with continous-interval data
  10. methods of presentations: (differences & similarities) 
    - know the difference between bar graph and histogram
    • Histogram is similar to bar graph, but horizontal axis usually reppresent the continous-interval categories rather than discrete categories used in the bar graph
    • Height of bar graph displays the frequency of each category
    • Histograms are used when the distribution of the data needs to be emphasized more than the value
  11. methods of presentations: (differences & similarities) 
    - pie chart: determine the angles
    • 360 chart
    • divided into sections
    • each section represents the frequency of each category (by relative frequency)
  12. Methods of presentations: (differences & similarities) 
    - frequency polygon/line graph
    • Displays continous data
    • Shows relationship between two variables
    • Horizontal (x)axis shows independant data
    • Vertical (y)axis shows the dependant data
    • the area under the polygram (line) displays the frequency
  13. methods of presentations: (differences & similarities) 
    - Rules for preparing a graph
    • Must have title
    • time period, if appropriate
    • author (who prepared it)
    • source of data (monthly stats, medical record, etc.)
    • date of graph
    • breif staetment, if special study
    • keep graphs simple
  14. Difference between a birth and a delivery
    Birth is the act or process of bearing or bringing forth offspring; childbirth ; parturition:

    Delivery expulsion or extraction of the child and fetal membranes at birth.
  15. ACOG/ICD-9 classification of gestational age
    • Early fetal death = less than 20 weeks (500g or less)
    • Intermediate fetal death = 20-27 weeks
    • Late fetal death = 28 weeks or later
  16. -          Available bodies (bodies included/excluded in the denominator)
    -                   - hospital autopsy
    -                   - gross autopsy
    -                   - fetal autopsy
    -                   - net autopsy
  17. Reporting Vital Statistics (points of distribution)
    • Births
    • Death
    • Fetal death

    Vital stats provide valuable information to private individuals, public health and welfare information, laywers, research and social workers.
  18. Calculations:
    ·         Includes: Length of stay (LOS)
  19. Calculations:  Average LOS
  20. Calculations: c-section rate,
  21. Calculations: consultation rate,
  22. Calculations: infection rate,
  23. Calculations: autopsy rate,

  29. Hospital autopsy
    # of autopsies for period/# of death of hospital available for hospital for that period
  30. Fetal Autoposy rate
