## 4 Case Study: Oncology Department
### Experiment and Results  
The average medical staff response time in the example of the oncology department from Figure 2 at full capacity when a total of 31 patients receive IV chemotherapy according to PEB or PEI protocol, was determined experimentally. Therefore, the total number of IV  
Figure 2: An example of an oncology department: room for nurses (R-A1), room for cytostatics preparation and other medical supplies (R-A2), room for clean linen (R-A3), bathroom for hospital staff (R-A4), room for doctors (R-A5), room for head nurse (R-A6), room for ECG and other minor diagnostics (R-A7), room for medical equipment including mobile and stationary devices and instruments (R-A8), room for housekeeping staff (R-B1), room with material for hospital cleaning and disinfection (R-B2), rooms for patients with two beds each in which there are isolated or immobile patients (PR-1, PR-2, PR-3, PR-4, PR-5), and rooms for patients with seven beds each in which there are mobile patients (PR-6, PR-7, PR-8). bottles to be placed, turned on and off, was 165. In addition, the trajectory of the medical staff from the cytostatic room (R-A2) is shown in Figure 2 in the form of black arrows for each individual patient. Thus, the distance from the cytostatic room to the farthest patient (P4 or P5) was calculated to be 53 m.  
Within the experiment, a total of 50 healthy and adult subjects participated, of which 40 (80%) were women (nurses) and 10 (20%) were men (medical technicians) in four age groups: a total of 27 subjects (54%) were from 18 to 25 years old; a total of 8 subjects (16%) were from 25 to 30; a total of 8 subjects (16%) were from 35 to 45 and a total of 7 subjects (14%) were from 45 to 55 years old. All the subjects performed the task of crossing a straight path with a total length of 53 m for two different scenarios--spontaneous and fast walking. Times were measured using a stopwatch. Table 2 shows the results of the experiment for the female, male, and total sample. In addition, for each age group, depending on the scenario, data for minimum, main, and maximum walking times as well as standard deviation are given. The first part of the table refers to female subjects representing 80% of the total number of subjects in the experiment. The first age group included a total of 21 subjects (52.5%), the second a total of 7 subjects (17.5%), while the third and fourth groups had a total of 6 subjects (15.0%) each. Therefore, the response time of female subjects during the spontaneous and fast walk was in the intervals of 24.05-35.34 s and 21.69-31.46 s, respectively. The shortest main reaction time was recorded in the first group and the longest in the fourth group. In addition, the major times of all female subjects in the spontaneous and fast walk were 30.61 \(\pm\) 2.22 s and 25.33 \(\pm\) 2.04 s, respectively. The second part of the table refers to male subjects representing 20% of the total number of subjects in the experiment. The first age group includes a total of 6 subjects (52.5%), the second and fourth a total of 1 subject each (10%), while the third group a total of 2 subjects (20%). Therefore, the reaction times of male subjects during spontaneous and fast walking were in the range of 25.24-31.84 s and 20.25-25.64 s, respectively. The shortest main reaction time was recorded in the second group, while the longest was in the fourth
