The coronavirus pandemic, since its inception, has shown great and significant consequences on all aspects of human life. One of the most important roles in the fight against the pandemic is played by health professionals who not only have to function adequately, quickly and efficiently on their job, but also have to face and solve problems and difficulties in their personal life. The turbulent period of the pandemic is primatily reflected in the increased levels ov stress that health professionals feel in the workplace on a daily basis, due to major changes in the entire health system. The aim of this paper is to examine the level and sources of stress in nurses and technicians employed at COVID and non-COVID departments at KBC Split. We hypothesized that there would be a statistically significant difference in the level of perceived stress between nurses and technicians from the COVID department compared to those from the non-COVID department. COVID employees should show statistically significantly higher levels of stress. The questionnaire used in this study consisted of four parts. The first part referred to demographic data, the secon part is the Patient Health Questionnaire for Depression and Anxiety 4 (PHQ-4) with four questions, the third part is the Percieved Stress Scale 4 (PSS-4), while the fourth part covered questions about the use od mental health preservation techniques. The hypothesis has been confirmed, meaning that COVID employees truly experience higher levels of stress at work than non-COVID employees. The most commonly usen mental health techniques are exercise and prayer.
