MÉTODOS DE AVALIAÇÃO DA LIMPEZA E DESINFECÇÃO DE SUPERFÍCIES EM PERÍODO PANDÊMICO: ESTUDO CORRELACIONAL

Abstract

Introduction: In healthcare settings, environmental control of cleaning and disinfection of surfaces is essential to reduce healthcare-associated infections. Contaminated surfaces serve as reservoirs for microorganisms. In this sense, it is important to understand the correlation between monitoring methods. Objective: To correlate the methods of assessing cleaning and disinfection of surfaces in a respiratory syndrome unit during the pandemic period and to verify the adenosine triphosphate cutoff point. Method: A quantitative correlational study. Data were collected from April to June 2022 in an Acute Severe Respiratory Syndrome Treatment Unit integrated into a Primary Care Unit of the Unified Health System. Results: The study did not find a significant correlation between the quantification of adenosine triphosphate by bioluminescence and microbial count on most of the surfaces and stages evaluated, except for the mattress in phase I, where there was a strong positive correlation. The ROC curve revealed that adenosine triphosphate quantification is more sensitive in identifying clean surfaces, while microbial count is more specific in detecting contaminated surfaces.Conclusion: However, neither method showed a significant comparative relationship. The cutoff value for adenosine triphosphate was equal to or less than 67 RLU to consider the surface clean in this study.
