Critical care nurses have high workloads due to the severity of the disease and the complexity of the treatment and care. Understanding the factors that influence subjective workload as well as the association between subjective and objective workload could lead to new insights to reduce critical care nurses' workload. (1) To describe critical care nurses' subjective and objective workload per shift in a university-affiliated interdisciplinary adult intensive care unit in Switzerland and (2) to explore the association between objective and subjective workload. The study used a prospective longitudinal cohort design. Critical care nurses completed the adapted Questionnaire on the Experience and Evaluation of Work 2.0 (QEEW2.0) to assess the subjective workload after every shift for four weeks (0 = never loaded, 100 = always loaded). The objective workload was assessed with the Therapeutic Intervention Scoring System-28 (TISS-28), Nine Equivalents of Nursing Manpower Use Score (NEMS), Swiss Society for Intensive Care Medicine (SGI)-patients' categories and Patient-to-Nurse Ratio (PNR). Data was analysed using multilevel mixed models. The workload of 60 critical care nurses with a total of 765 shifts were analysed. The critical care nurses experienced a subjective high mental load (66 ± 26), moderate pace and amount of work (30 ± 25) and physical load (33 ± 25), and low emotional-moral load (26 ± 22). The one-time baseline subjective workload values were higher than the day-to-day values. The mean objective shift load using the TISS-28 was 43 ± 16 points, the NEMS 36 ± 14 points, the SGI-category 1.1 ± 0.5 nurses needed per patient and the PNR 1.2 ± 0.4. We found positive associations between day-to-day objective variables with subjective pace and amount of work, with physical and mental load but not with emotional-moral load and performance. Measured objective workload is associated with only certain subjective workload domains. To promote and retain critical care nurses in the profession, nursing management should give a high priority to understanding subjective workload and strategies for reducing it.
