“…Alternatively, a study carried out in a primary healthcare unit observed a decrease in microbial charge through ACC and ATP bioluminescence on five surfaces by comparing outcomes obtained before and after the implementation of a cleaning and disinfection program. This effect persisted for two months, when a new assessment was performed using the same techniques [7].…”

“…Several aspects may be related to negative impacts of interventions and help explain these results. The main ones are nonadherence to the protocol; inadequacy of the executed procedures; use of contaminated materials, utensils or equipment; and lack of feedback to the team [7, 16]. The latter has been pointed out as a decisive element to achieve positive results, given that it tends to encourage the team, allowing the team to raise awareness of its role in behavior change.…”

“…There are many factors related to the positive performance of an intervention oriented toward surface cleaning and disinfection monitoring, such as measuring ATP bioluminescence. However, involvement and interest in the improvement of surface cleaning processes is determined in terms of its efficacy [7, 12].…”

“…The third step consisted of the standardization of surface cleaning and disinfection practices, such as cleaning routines and the use of microfiber cloths (80% viscose, 15% polypropylene, and 5% polyester). It was decided that microfiber cloths should be folded into four parts, every side should be used, and replacement would happen whenever necessary [7].…”

Background Cleaning and disinfection processes must be improved so that there is a reduction in environmental contamination of frequent-contact surfaces. The objective of this study was to evaluate cleaning and disinfection of surfaces at a specialized healthcare unit after an intervention program. Methods Exploratory, longitudinal, and correlational study carried out in a medium-complexity clinic. Two hundred and forty samples from five surfaces were collected during three phases: diagnosis; implementation of an intervention program; and evaluation of immediate and long-term effects. In total, 720 evaluations were made, performed through three monitoring methods: visual inspection; adenosine triphosphate bioluminescence assay (ATP); and aerobic colony count (ACC). The Wilcoxon, Mann-Whitney, and Fisher’s Exact tests were run to analyze data statistically. Results Cleaning and disinfection of surfaces were not being performed properly in most cases. Failure rates of surfaces reached 37.5 and 100% when the ATP and ACC procedures were used, respectively. However, after an intervention program, an improvement occurred. Success rates increased by 43.96% (ATP) and 12.46% (ACC) in phase I, by 70.6% (ATP) and 82.3% (ACC) immediately after interventions, and by 76.52% (ATP) and 85.76% (ACC) two months after the changes, showing that the program was effective. Conclusion The present study reveals that implementing intervention actions with a cleaning and healthcare team brings benefits to prevent the spread of pathogenic agents through frequently touched hospital surfaces.

In the constructed habitat in which we spend up to 90% of our time, architectural design influences occupants' behavioral patterns, interactions with objects, surfaces, rituals, the outside environment, and each other. Within this built environment, human behavior and building design contribute to the accrual and dispersal of microorganisms; it is a collection of fomites that transfer microorganisms; reservoirs that collect biomass; structures that induce human or air movement patterns; and space types that encourage proximity or isolation between humans whose personal microbial clouds disperse cells into buildings. There have been recent calls to incorporate building microbiology into occupant health and exposure research and standards, yet the built environment is largely viewed as a repository for microorganisms which are to be eliminated, instead of a habitat which is inexorably linked to the microbial influences of building inhabitants. Health sectors have re-evaluated the role of microorganisms in health, incorporating microorganisms into prevention and treatment protocols, yet no paradigm shift has occurred with respect to microbiology of the built environment, despite calls to do so. Technological and logistical constraints often preclude our ability to link health outcomes to indoor microbiology, yet sufficient study exists to inform the theory and implementation of the next era of research and intervention in the built environment. This review presents built environment characteristics in relation to human health and disease, explores some of the current experimental strategies and interventions which explore health in the built environment, and discusses an emerging model for fostering indoor microbiology rather than fearing it.

Background: Understanding the correlation between the methods of monitoring surface cleaning and disinfection (SCD) is fundamental for better infection control. Purpose: This study aims to correlate the SCD monitoring methods in a Brazilian pediatric unit. This is an exploratory, longitudinal, and correlational study. Methods: The study was conducted in a pediatric hospitalization unit of a medium-sized hospital from December 2020 to March 2021. Four high-contact surfaces were analyzed before and after the cleaning and disinfection process by means of visual inspection, quantification of adenosine triphosphate (ATP), and colony-forming unit (CFU) count. The study consisted of three stages: stage I involving situational diagnosis of the SCD process; stage II referring to the implementation of the Surface Cleaning and Disinfection Standardization Program (SCDSP); and stage III involving long-term assessment after implementing the program. A total of 192 assessments were performed in each stage, totaling 576 in the three study stages. Conclusions: A significant correlation was found between the ATP quantification methods and microbial count in the bed railing ( p = 0.009) and companion’s armchair ( p = 0.018) surfaces. In both cases, Spearman’s correlation coefficients were positive, indicating a positive correlation between ATP and microbial count scores, that is, the higher the ATP values (in RLUs), the greater the microbial counts (in CFUs/cm2). The analysis of the ROC curves suggests that the surfaces presenting ATP below 108 RLUs can be considered approved. The ATP method yielded 78.6% sensitivity; in turn, microbial count presented a sensitivity of 85.7%. It is important to use different methods to monitor the cleaning and disinfection of surfaces, as each one has different sensitivity and specificity.
