| Abstract | Cilj istraživanja je ispitati razlike u doživljenoj razini stresa koju izazivaju različiti aspekti rada u dvorani kod anestezioloških tehničara i medicinskih sestara/tehničara JIL-a.
Metode: U empirijskom dijelu ovog rada primjenom kvantitativnih metoda u biomedicini testira se važnost odabranih čimbenika stresa. U radu se koriste metode grafičkog i tabelarnog prikazivanja, metode deskriptivne statistike, Wilcoxonon test za jedan nezavisni uzorak, te T-test za jedan idva nezavisna uzorak. Metodama grafičkog i tabelarnog prikazivanja prikazana je struktura odgovora ispitanika, dok je metodama deskriptivne statistike prikazana srednja vrijednost čimbenika stresa sa pripadajućim odstupanjima među ispitanicima. Postojanje stresa testirano je Wilcoxon testom za jedan uzorak gdje je proveden test na način da se utvrdi postojanje niske, umjerene ili visoke razine stresa, dok je razina ukupnog stresa testirana T-testom. Razlika u razini stresa između anesteziološki tehničara i medicinska sestra/tehničar u JIL-u testirana je T-testom gdje je testirana razlika u ukupnoj razini stresnosti. Opravdanost korištenja parametrijskog T-testa proizlazi iz obilježja varijable ukupne stresnosti koja ima obilježja kontinuirane numeričke varijable, te je zadovoljen uvjet normalnosti distribucije (normalnost testirana Kolmogorov-Smirnovim testom). Analiza je rađena u statističkom softwareu STATISTICA 12. Zaključci su doneseni pri razini signifikantnosti od 5%.
Rezultati istraživanja pokazuju kako najvišu razinu stresa među medicinskim osobljem izaziva čimbenik nedostatnog broja djelatnika, nakon čega slijedi preopterećenost poslom, neadekvatna materijalna sredstva za rad (financijska ograničenja), loša organizacija na poslu, te čimbenik oskudne komunikacije sa nadređenima. Riječ je o pet čimbenika koji su u najvećoj mjeri izraženi među zdravstvenim osobljem. Najveći broj ispitnih medicinskih djelatnika iskazao je visoku razinu stresa uzrokovanom lošom organizacijom na poslu (37,7%), vremenskim ograničavanjem za pregled pacijenta zbog stresa (29,31%), oskudna razina komunikacije s nadređenima (36,07%), malom mogućnosti napretka i promaknuća (34,43%), nedostatnim brojem djelatnika (45,90%), svakodnevnim nepredviđenim ili neplaniranim situacijama (30,51%), te straha od izloženosti ionizacijskom zračenju (27,87%). Nepostojanje stresa kod najvećeg broja ispitanih medicinskih djelatnika utvrđeno je za dežurstvo (24 sata; 35,29%), uvođenje novih tehnologija (30%), prijetnja sudske tužbe i parničenja (27,87%), te straha zbog izloženosti citostaticima. Dokazana je viša je razina stresa među anesteziološkim tehničarima u odnosu na medicinske sestre/tehničare u JIL-u.
Zaključci: Na temelju empirijske t vrijednosti 3,42 pri 59 stupnjeva slobode donosi se zaključak da postoji statistički značajna razlika u razini čimbenika stresa na radnom mjestu među medicinskim sestrama/tehničarima u JIL-u i anesteziološkim tehničarima. Zaključak je donesen pri empirijskoj razini signifikantnosti <0,001 te je time potvrdio postavljenu hipotezu. |
| Abstract (english) | Main goal of this research is to examine differences in experienced levels of stress which are caused by several different aspects of work in the gym with anesthesiologists and JIL's nurses/technicians.
Methods: Stress factors' importance is tested in empiric part of this paper by applying quantative methods in biomedicine. Methods of graphic and table representation, methods of descriptive statistics, Wilcoxon's test for independent sample and T-test for one and two independent samples are used in this paper. Structure of subject's answer is shown by methods of graphical and table representation, while average value of stress factors with associated deviations among subjects is shown by methods of descriptive statistics. Existence of stress is tested by Wilcoxon's test for one sample, where the test is carried out in order to determine the existence of low, medium or high levels of stress, while the total amount of stress is tested by T-test. Differences in stress levels between JIL's anesthesiologist and nurse/technician were tested by T-test, where the differences in stress levels were examined. T-test parameter justification of usage comes out of total stress variable mark which has marks of continuous numeric variable, and when term of normality distribution (normality tested by Kolmogorov-Smirnov test) is being met. Analysis was made in statistics software "Statistica 12". Conclusions were carried out with significance level of 5%.
Research results are showing that the highest levels of stress within medical staff are caused by factor of missing number of staff, which is followed by work overload, non-adequate material resources for work (financial restrictions), bad work organization and the factor of low level communication with superiors. There are 5 factors which are the most expressed ones between medical staff. The biggest part of questioned medical staff expressed high levels of stress caused by poor work organization (37,7%), time limits for patient examination for stress (29,31%), poor level of communication with superiors (36,07%), low chances for progress and promotion (34,43%), insufficient number of staff (45,90%), unpredicted or unplanned situations on daily basis (30,51%) and fear of being exposed to ionizing radiance (27,87%).
Lack of stress was laid down for staff on duty (24 hours; 35,29%), introduction of new technologies (30%), threat of law suit and judicial proceeding (27,87%) and fear of citostatic exposure. Higher levels of stress were proven to exist among anesthesiology technicians than among JIL's nurses/technicians.
Conclusions: Existance of statisticaly significant difference in levels of stress on work place among JIL's nurses/technicians and anesthesiology technicians was concluded on basis of empiric t value of 3,42 with 59 degrees of freedom. Conclusion was made with empiric significance value of <0,001.
The lack of stress at the highest number of medical personnel surveyed was established for day care (24 hours, 35.29%), introduction of new technologies (30), threats of court action and litigation (27.87%), and fear of exposure to cytostatics. There is a higher level of stress among anesthesiologists compared to JIL's nurses/ technicians.
Conclusions: Based on the empirical value of 3.42 at 59 degrees of freedom, it is concluded that there is a statistically significant difference in the level of stress factors at workplace among nurses/ technicians in JIL and anesthesiologists. The conclusion was reached at the empirical level of significance <0.001. |
