The effects of the reorganisation of an intensive care unit due to COVID-19 on nurses' wellbeing: An observational cross-sectional study.

OBJECTIVES: To evaluate the effects of the reorganisation of an intensive care unit for COVID-19 patients in the context of the SARS-CoV-2 pandemic on wellbeing perceived by nurses. METHODS: An observational cross-sectional study was conducted to evaluate wellbeing perceived by nurses who during the study were on duty in the COVID-19 intensive care unit. The "Covid-19-Nurse Well-being at Work (NWB) scale" questionnaire consisting of 72 items divided into 13 sections, was validated and used to collect data. RESULTS: The level of wellbeing perceived by the nurses was very good (4.77; SD 0.83). Differences in the of level of perceived wellbeing were found for "years of experience" and the various levels of competence. We found a positive correlation between "female gender" and "nurses' togetherness and collaboration", a negative correlation between "male gender" and "satisfactory practical organisation of work, and a negative correlation between "work experience" and the overall "level of wellbeing at work. CONCLUSIONS: The reorganisation had positive effects in terms of wellbeing perceived by the nurses. The factors that contributed mostly to the perception of wellbeing were in the area of "support", "communication, and "socializing with colleagues". It is appropriate to consider "gender differences", "work experience" and "levels of competence" when implementing this type of reorganisation to respond to a pandemic or a health emergency.

Improving Cleaning and Disinfection of High-Touch Surfaces in Intensive Care during Carbapenem-Resistant Acinetobacter baumannii Endemo-Epidemic Situations.

Aims: High-touch surfaces cleaning and disinfection require the adoption of effective and proper executed protocols, especially during carbapenem-resistant Acinetobacter baumannii (CRAB) endemo-epidemic situations. We evaluated the effectiveness and residual disinfectant activity of disposable pre-impregnated wipes (Modified Operative Protocol, MOP) in reducing environmental bioburden versus a two-step Standard Operative Protocol (SOP) in a 12-bed Intensive Care Unit. Methods: Five high-touch surfaces were cleaned and disinfected either according to the SOP (alcohol-based cleaning and chlorine-based disinfection) or using quaternary ammonium compounds-based disposable wipes (MOP). Sampling was performed before each procedure and at 0.5, 2.5, 4.5 and 6.5 h after (560 sites). Total viable count (TVC) was evaluated according to Italian hygiene standard (<50 CFU/24 cm²). Clinical and environmental CRAB strains isolated were genotyped. Results: On non-electromedical surfaces the difference between TVC before procedure and at each of the following times was significant only for the MOP (p < 0.05, Wilcoxon test). Using the MOP, only 7.4% (10/135) of sites showed TVC >50 CFU/24 cm² (hygiene failures) versus 18.9% (25/132) after SOP (p < 0.05, Fisher's Exact test). On infusion pumps a higher number of hygiene failures was observed after the SOP (7/44, 15.9%) compared with the MOP (4/45, 8.9%). Genotyping highlighted a common source of infection. Conclusion: On high-touch surfaces, the use of disposable wipes by in-house auxiliary nurses may represent a more effective alternative to standard cleaning and disinfection procedure performed by outsourced cleaning services, showing effectiveness in reducing microbial contamination and residual disinfection activity up to 6.5 h.
