Ŀ   The more detailed way:                                                        1 out of HOW MANY cases, working shifts or any other regulated/regular        "time or action unit" does the Tested Worker suffers an injury (sharp         trauma, stick, stab, jab, bite or any other injury where he or she            actually exposed to the blood or other bodily fluids known to POTENTIALLY     contain HIV)?                                                                 It makes no difference whether the source of injury is HIV+ or not.           That is accounted for elsewhere in this program. The answer is related        strictly to the frequency of accidents.                                                                                                                        Ŀ                                                           More explanations:                                                           Ŀ        How many Encounter (or potential accident)  goes by WITHOUT an actual         accident. For example: if a surgeon claims that he gets stuck with a          scalpel or needle 1 out of every 5 Encounters (operations,cases), the         number should be entered is a 5  [Suggested:5-30]                                                                                                                  Ŀ   Another example: A floor nurse works 6 hours a day. During every Shift        she has to administer shots. For her, that 6 hours period of time, counts     as an Encounter. If she works 18 Shifts in one month (6 hours each) and       she claims (or incident reports show) that she gets stuck, or exposed to      some other way, to a potential source of HIV once in every 2 month, then      the number entered here, should be 36 (2 x 18 shifts)                                                                                                       Meaning: She suffers an injury in 1 out of 36 shifts.                         An injury of course is only a potential exposure to HIV, hence if the         patient is HIV negative, there will be no HIV transmission.                                                                                                    Ŀ                                                              Advanced usage:                                                              Ŀ   The Simulator is capable to Simulate a Group of individuals, in which the     individuals has very similar exposure characteristics. In order to            activate that feature, press the TAB key on your keyboard and answer the      questions related to the Group.                                                                                                                             Example: There is a hospital, which has a "surgical ward" on each floors.     The surgical patients are randomly distributed, wherever there is an          empty bed, that is where the next will go, thus each ward has the same        type of patient population.                                                                                                                                 You want to simulate the "AIDS time-risk" for all LPN's (Licensed             Practical Nurse). Say there are 50 LPN's on those surgical wards and          their duties are similar, the number of hours they work are similar.          Every hospital has an "incident report" system, where every employee must     report if anything irregular happens, such as being stuck by a needle,        being exposed to blood, slipping on the hallway, etc.                                                                                                       Every hospital compiles those reports into a year end statistics,             therefore they all have the figures regarding a particular type of            incident and that how many of them happened through a year, or any other      given time period. Such as: the 50 "surgical floor" LPN's had a total of      150 incidents which involved a "skin penetrating" injury.                                                                                                   The numbers needed for this question:                                         a) the number of individuals in that given group                              b) the total number of such accidents                                         c) The number of months during which those numbers were collected.               Usually it is a year, but the Simulator accommodates for other time           intervals.                                                                                                                                               If you have these numbers, exit the help and press the TAB key and answer     these questions at the middle of the screen.                                   Ŀ                       What the result will indicate for Group calculations:                       Ŀ   If the above inputs were properly provided, at the conclusion of the          simulation, the                                                               "Tested Worker will most likely contract AIDS within the next 6.7 years"      display will apply to each member of the tested Group.                        Needless to say, this is a crude approximation, but it can give you a not     so accurate, but still within the realm of the problem, result.               Assume that it is not so accurate and it is really not 6.7 years to any       of the given individuals in the group, but it is 7.5 years.                   Regarding the topic we are discussing, would it really make any difference?
