 Exam 3 10/16/12 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 types of data - nominal  Also called categorial, qualitative or named dataInclude numeric values assign to catergoriesExample: Male =0 Female=1 types of data - ordinal Represent rankings according to some criterion Example: Severity of illness0=no risk illness1=low risk2=moderate risk3=high risk4=severe risk 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) types of data - continuous Continous data assumes an infinite number of possible values Example: charges(cost) or weight 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 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 variableHorizontal (x) shows discrete categoryVertical (y) shows the frequency  methods of presentations: (differences & similarities)  - histograph Used to represent frequency distributive with continous-interval data 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 graphHeight of bar graph displays the frequency of each categoryHistograms are used when the distribution of the data needs to be emphasized more than the value methods of presentations: (differences & similarities)  - pie chart: determine the angles 360 chartdivided into sectionseach section represents the frequency of each category (by relative frequency) Methods of presentations: (differences & similarities)  - frequency polygon/line graph Displays continous dataShows relationship between two variablesHorizontal (x)axis shows independant dataVertical (y)axis shows the dependant datathe area under the polygram (line) displays the frequency methods of presentations: (differences & similarities)  - Rules for preparing a graph Must have titletime period, if appropriateauthor (who prepared it)source of data (monthly stats, medical record, etc.)date of graphbreif staetment, if special studykeep graphs simple 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. ACOG/ICD-9 classification of gestational age Early fetal death = less than 20 weeks (500g or less)Intermediate fetal death = 20-27 weeksLate fetal death = 28 weeks or later -          Available bodies (bodies included/excluded in the denominator) -                   - hospital autopsy -                   - gross autopsy -                   - fetal autopsy -                   - net autopsy Reporting Vital Statistics (points of distribution) BirthsDeathFetal death Vital stats provide valuable information to private individuals, public health and welfare information, laywers, research and social workers. Calculations: ·         Includes: Length of stay (LOS) Calculations:  Average LOS Calculations: c-section rate, Calculations: consultation rate, Calculations: infection rate, Calculations: autopsy rate, Calculations: death rate, Calculations: occupancy rate 3 reportable statistics BirthDeathFetal death Autopsy the inspection and partial dissection of a dead body to learn the cause of death and the nature and extent of disease Net Autopsy Only IP are included / Total IP -coronors cases Hospital autopsy # of autopsies for period/# of death of hospital available for hospital for that period Fetal Autoposy rate i & l fetal deaths for period/Total i&l fetal deaths Gross autopsy IP autopsied/total deaths (A&C, NB) Stats taken from Death Cert. helps who evaluate? underlying causes of deathdeath rate trendsmultiple causes of deathfrequency of conditions that occur together Points distribution for fetal death form go to: Copies to NCHS & local agencyOriginal to state Who is responsible for fillingout death cert?
