114 Results differences in nursing workload per patient category Figure 3 shows the mean Nursing Activities Score per patient for the COVID-19 patients compared with the pneumonia patients and the non-COVID-19 patients compared to the non-pneumonia patients. We found a significant higher Nursing Activities Score in COVID-19 patients compared to the pneumonia patients (Median (IQR) 55.2 (44.9 – 64.8) vs 50 (40.4 – 55.6), p<0.001). The Nursing Activities Score of both groups of other ICU patients (non-COVID-19 patients during the pandemic and non-pneumonia patients in a recent non-COVID-period) was not significantly different (Median (IQR): 42.6 (38.5 – 46.9) vs 42.9 (29.5 – 51.0), p 0.037). We also compared the Nursing Activities Score per patient of the COVID-19 patients to the other ICU patients in the COVID period. We found a significant higher Nursing Activities Score in COVID-19 patients (Median (IQR) 55.2 (44.9 – 64.8) vs 42.6 (38.5 – 46.9), p<0.001). 0 20 40 60 80 100 120 NAS per patient Year NAS 2020 2019 2020 2019 COVID Pneumonia Non−COVID Non−pneumonia Figure 3. differences in NAS per patient of COVID-19 versus pneumonia patients and non-COVID versus non- pneumonia patients Comparing the type of nursing interventions of the COVID-19 patients with the pneumonia patients, we found a significant difference in all the nursing interventions except for one intervention; care for the patients with a cardiopulmonary resuscitation after arrest in the past 24 hours (Table 2).
