Characteristics of the study population.

Introduction
Non-beneficial stays in the intensive care unit (ICU) may have repercussions for patients and their families, but can also cause suffering among the nursing staff. We aimed explore the perceptions of nursing staff in the ICU about patient stays that are deemed to be “non-beneficial” for the patient, to identify areas amenable to intervention, with a view to improving how the nursing staff perceive the patient pathway before, during and after intensive care.
Methods
Multicentre, qualitative study using individual, semi-structured interviews. All qualified nurses and nurses’ aides who were full-time employees in the ICU of three participating centres were invited to participate. Interviews were recorded, transcribed and analyzed using textual content analysis.
Results
A total of 21 interviews were performed from February 2020 to October 2021, at which point saturation was reached in the data. Average age of participants was 38.5±7.5 years, and they had an average of 10.7±7.4 years of experience working in the ICU. Four major themes emerged from the interviews, namely: (1) the work is oriented towards life-threatening emergencies, technical procedures and burdensome care; (2) a range of specific criteria and circumstances influence the decisions to admit patients to ICU; (3) there are significant organisational, physical and psychological repercussions associated with a non-beneficial stay in the ICU; (4) respondents made some proposals for improvements to the patient care pathway.
Conclusion
Nursing staff have a similar perception to physicians regarding admission decisions and non-beneficial ICU stays. The possibility of future ICU admission needs to be anticipated, discussed systematically with patients and integrated into healthcare goals that are consistent with the patient’s wishes and preferences, in multi-professional collaboration including nursing and medical staff.
