Perceived psychological stress associated with medical device noise among healthcare workers

Hospitals rely on medical devices such as ventilators, infusion pumps, and patient monitors, but the noise they generate can impact healthcare workers’ well-being. This study examines the stress and burnout levels linked to medical device noise among Intensive Care Unit (ICU) nurses in a tertiary hospital. Using a mixed-methods approach, data were gathered through structured questionnaires incorporating the Perceived Stress Scale (PSS-10) and the Maslach Burnout Inventory (MBI). Results showed that 39.2% of nurses reported low stress, 35.3% moderate stress, and 25.5% high stress due to noise exposure. Burnout assessments revealed moderate emotional exhaustion (10%) and depersonalization (4%), though all (100%) participants maintained a sense of accomplishment. Regression analysis found no significant relationship between years of work experience and perceived stress (r = 0.063, p = 0.661). Qualitative data highlighted concentration difficulties, communication challenges, and emotional strain, with some nurses reporting sleep disturbances and alarm-related auditory hallucinations. While many adapted to the noise, concerns about its impact on safety persisted. These findings highlight the need for hospital-wide strategies to minimize noise-induced stress and enhance the work environment for healthcare providers.
