The idea behind the implementation of nursing workload measurement tools was to deliver an evidence-based decisionmaking process, guaranteeing transparency of policy and achieving a higher level of efficiency. However, the concept of "nursing workload" is still complex and difficult to define. Currently, the main validated tools for nursing workload monitoring are: 1) Simplified therapeutic intervention scoring system (TISS 28) (Miranda et al, 1996) , 2) Nine equivalents of man power score (NEMS) (Miranda et al, 1997) and 3) Nursing Activities Score (NAS) (Miranda et al, 2003) . The staff skill mix should be adjusted on the basis of the resulting scores. The patient's clinical complexity could be, in selected cases, a good proxy for measuring nursing complexity. An example of this correlation is represented by patients undergoing extracorporeal membrane oxygenation (ECMO). The Extracorporeal Life Support Organization (ELSO) guidelines suggest that these patients should be centralised in referral centres where, an adequate nurse-to-patient ratio could be guaranteed in addition to the technical equipment. The use of NAS in an Italian ECMO centre, demonstrated that the nurse to patient in ECMO ratio was between 1: 1.5 and 1: 1 (Lucchini et al., 2019) Padilha et al. (2008) investigated the associations between NAS and patients' variables such as gender, age, length of stay, ICU discharge, ICU management, Simplified Acute Physiology Score II (SAPS II) and TISS-28. This study shows that the highest NAS scores were associated with increased mortality, length of stay, severity of the patient illness (SAPS II) and particularly to TISS-28 in the ICU. Recently Staveseth et al. (2018) , showed that NAS highlights nurses' workload and may be a helpful classification system to be used in planning and budgeting of intensive care resources. A statistically significant association was found between monthly costs, NAS and NEMS; therefore, the cost of care should be reckoned on the individual patients' nursing care needs. However, the greatest challenge related to nursing workload is represented by the levels of nursing complexity management in ICU patients. Kisse et al. (2020) , have used the "King's-TISS" score to evaluate the nursing workload and the ideal nurse-to-patient ratio, in the first 48 hour perioperative period after blood product free liver transplantations. The authors found that the absence of blood product administration in liver transplantations decreased the total and organ specific workload, with the exception of metabolic, haemostasis, immunology conditions and for basic support (Negro et al., 2020) . Moreover, in this (unexpected) COVID-19 era, new factors can tremendously influence nursing workload. COVID-19 patients require prophylactic measures to prevent or contain the spread of the virus to other patients: donning protective garments, specific decontamination procedures, isolated dedicated areas where specific supplies are stored. All these measures increase nursing workload (Giuliani et al., 2018) , not only for the time required of their implementation but also for their organisation and management. Critical care nurses are experiencing a new challenging working scenario inside the COVID-19 ICUs. In these setting, they are called to provide the usual high standard care of patients with the additional problems caused by the personal protective equipment, especially for long periods. COVID-19 ICU patients cannot receive external visitors, they are dependent on support from healthcare workers. The sudden lack of ICU beds and mechanical ventilators for ICU patients has led to an increasing number of conversions of recovery and operating rooms into new COVID-19 areas. (Bambi et al., 2020; . New ICU beds were designated and critical care nurses were needed to manage patients who were dependant on high tech organ and system support (including ECMO) (Bambi et al., 2020; Lucchini et al.2020) . Some preliminary reports identify the nursing workload is dramatically high in COVID-19 patients Reper et al., 2020) . In addition to the severity of illness, the nursing workload increased because of the need to provide humanistic care in the absence of family. The introduction of mobile phone calls (Negro et al., 2020) also helped patients to mitigate their sense of isolation and keep them and their relatives updated, about what is happening outside and inside "the hospital walls". When people affected by COVID-19 enter the hospital, they literally disappear from their relatives' lives. Therefore, the COVID-19 era is driving the need to enhance nursing workload scores with new issues, including the time for donning and doffing PPE, the additional time taken to provide care wearing PPE, the need for distanced communication between patient and relatives and the need to manage the increasing incidence and severity of agitation and delirium due to the isolated environment (Kotfis et al., 2020) .
