Introduction: Healthcare-associated infections (HAIs) are often caused by contaminated or inadequately cleaned surfaces and the hands of hospital personnel.
Aim: This study investigates and analyzes the levels of contamination on hospital surfaces, medical instruments, and staff hands.
Materials and Methods: A prospective study was conducted from June to August 2024 at St. Marina UniversityHospital in Varna. Adenosine triphosphate (ATP) monitoring was performed on 301 epidemiologically significant hospital objects. Sampling was carried out using the EnSURE system, including the Ultrasnap single-use device and a real-time test-reading device. The collected data were analyzed using descriptive statistics, as well as documentary and graphic methods.
Results: The study encompassed 21 clinics of St. Marina University Hospital in Varna. A total of 301 hospital surfaces were examined using the luminometry method to evaluate cleanliness. Of these, 54.3% (n=163) met acceptable ATP levels ("passes"), 13.6% (n=41) were classified as "cautionary," and 32.1% (n=97) exceeded acceptable levels ("failed").
Conclusion: The results indicate a significant adherence to hygiene standards in many cases but also highlight areas requiring improvement. Staff training to enhance competence in cleaning protocols is essential to minimize the risks of HAIs.
