Burnout symptoms, work motivation and their relationships among Italian ICU's nurses after COVID-19 emergency. A multicenter study.

Background: Despite the end of the health emergency, healthcare professionals are at risk of developing long-term mental health problems. The aim of this study was to observe Burnout symptoms and work motivation among Intensive Care Nurses, one year after admission to the Intensive Care Unit of the last positive SARS-CoV-2 swab patients.

Study design: A multicenter cross-sectional study design was carried out and a national web-based survey was conducted between April, 2023 and May, 2023 among 21 Italian Intensive Care Units.

Methods: The survey consisted of single- and multiple-choice questions structured into 3 sections: demographic sample data, Maslach Burnout Inventory Scale for the assessment of Burnout-symptoms and Multidimensional Work Motivation Scale for the assessment of work motivation.

Results: Four hundred-nine surveyed and questionnaires were included in the study. Of these 272 were male (66.5%). Burnout-related symptoms were identified in at least 79% of ICU nurses. Symptoms of severe Burnout was observed in 169 nurses analysed (41.3%) and they are significantly among nurses who had COVID-19 or positive SARS-COV-2 swab during the pandemic (RR= 1.55; CI= 1.24-1.95, p= .0004) and among nurses with at least one child (RR= 1.37; CI= 1.07-1.76; p= .011). Motivated nurses for the intrinsic motivation's level have been 281 (68.7%). The risk of being intrinsically demotivated is significantly greater among nurses with 5-10 years of work experience (RR= 2.44; CI= 1.48-4.02; p= .0002). Emotional exhaustion was associated in increase in demotivation and introjected estrinsic motivation. Depersonalization was associated with demotivation. Personal accomplishment was associated with increase in external estrinsic motivation and amotivation.

Conclusions: High level of Burnout has been observed among Italian ICU nurses associated with low work motivation after COVID-19 emergency. Interventions and strategies should be adopted to prevent burnout and improve work motivation.
