ABSTRACT

The aim of this study was to calculate the equation of correlation between the microbial air contamination values obtained by active sampling (colony-forming units per cubic metre, CFU/m3) and by passive sampling (Index of microbial air contamination, IMA), by using the data from the ISChIA study, and to compare the values obtained with the recommended limits defined by the EU Guidelines to Good Manufacturing Practice (EU GGMP), 2008, for clean areas used to manufacture sterile medicinal products. Air sampling was performed during 335 elective prosthesis procedures. Correlation between CFU/m3 and IMA values was evaluated using the Spearman test; p<0.05 was considered to indicate significance. This equation was used to calculate the IMA values corresponding to the CFU/m3 recommended threshold values by EU GGMP for the different Grades of microbial contamination. The following correlation equation was obtained: y = 1.86 + 0.12x, where "x" = cfu/m3 value and "y" = IMA value. The relationships between CFU/m3 and IMA values obtained from active and passive sampling during the ISChIA study showed to be in line to those suggested by the EU GGMP for pharmaceutical manufacturing for Grade C and D. This study shows that the EU GGMP relationship could be considered valid also for operating theatres. Both methods, active and passive samplings, can be used to evaluate microbial air quality and highlight critical situations; however, in particular during the activity, passive sampling estimating the risk posed by airborne microorganisms to the surgical wound, can be considered more relevant, and for its simplicity, economy and standardization, can be suggested for routine microbial monitoring.

ABSTRACT

The epidemic wave that hit Italy from February 21st, 2020, when the Italian National Institute of Health confirmed the first case of SARS­CoV­2 infection, led to a rapid and efficient reorganization of Dialysis Centers' activities, in order to contain large-scale spread of disease in this clinical setting. We herein report the experience of the Hemodialysis Unit of Parma University Hospital (Azienda Ospedaliero-Universitaria, Parma, Italy) and the Dialysis Centers of Parma territory, in the period from March 1st, 2020 to June 15, 2020. Among patients undergoing chronic haemodialysis, 37/283 (13%) had positive swabs for SARS­CoV­2, 9/37 (24%) died because of COVID-19. Twenty-three patients required hospitalization, while the remaining were managed at home. The primary measures applied to contain the infection were: the strengthening of personal protective equipment use by doctors and nurses, early identification of infected subjects by performing oro-pharyngeal swabs in every patient and in the healthcare personnel, the institution of a triage protocol when entering Dialysis Room, and finally the institution of two separate sections, managed by different doctors and dialysis nurses, to physically separate affected from unaffected patients and to manage "grey" patients. Our experience highlights the importance and effectiveness of afore-mentioned measures in order to contain the spread of the virus; moreover, we observed a higher lethality rate of COVID-19 in dialysis patients as compared to the general population.
