The goal was to determine the advantages and limitations of these rapid alternative tests in assessing the sanitary condition of hospital surfaces.Methods: A total of 88 samples were collected from various surfaces (stainless steel, metal, plastic, Tarkett, ceramic, glass, textile) in medical and surgical wards of a pediatric hospital. For each tested area, one sample underwent standard microbiological culture (25 cm²), and two adjacent samples (each 100 cm²) were analyzed using the ENSURE® TOUCH luminometer (Hygiena): one for ATP quantification (Ultrasnap) and one for ACC determination (Microsnap Total). Surfaces had been disinfected with commonly used agents—hydrogen peroxide, chlorinated products, or peracetic acid.Results: The Ultrasnap system identified 25 non-conforming samples; Microsnap Total found 13 non-conforming samples, while microbiological culture revealed one non-conforming sample and an additional 11 with low but detectable bacterial presence. The Ultrasnap method recorded a sensitivity of 100%, a specificity of 72.41% and an accuracy of 72.73%. In comparison, the Microsnap Total system showed higher specificity and accuracy (85.05% and 84.09%, respectively), but failed to identify the positive (non-conforming) test, resulting in a 0% positive predictive value.Conclusion: The study highlighted several advantages of rapid ATP tests, particularly their ease of use, their ability to provide results in just 10 seconds for Ultrasnap and approximately 7 hours for Microsnap Total, and their capacity to accurately identify well-sanitized surfaces. Additionally, Ultrasnap proved to be a sensitive indicator of residual organic matter, enhancing the capacity to distinguish between different sanitation levels and allowing cleaning and disinfection practices to be adjusted in real time, thereby reducing the risk of cross-transmission.Keywords: bioluminescence, ATP, disinfection, rapid assessment, hospital surfaces |
