The Effect of Fluorescent Marking and BCA Methods of Patient Unit Cleaning in Intensive Care

Patients admitted to the ICU are at great risk of developing nosocomial infections, partly because of their serious illness and partly because of exposure to life-saving invasive procedures. In ICU, implementation of invasive procedures, with the purpose of diagnosis and treatment, such as urinary catheter, central-peripheral catheter, intubation, and being subject to intensive antibiotic use increase the likelihood of infection. Environmental cleanliness is important for preventing infections.

Effective cleaning of surfaces in the hospital environment is an absolute necessity to reduce pathogen transmission. Multi Drug Resistant Organisms (MDRO) in ICU are among the leading causes of hospital-acquired infections. Today, the growing prevalence of MDRO has made it more important than ever to clean contaminated surfaces with appropriate aseptic cleaning procedures, to protect patients and personnel. Despite the disinfection and sterilization methods, microorganisms that reach a sufficient concentration in the hospital environment survive for long periods and can cause serious transmission via contaminated hands of healthcare workers. In this context, surface cleaning and disinfection procedures in the hospital environment reduce cross-contamination of the health care units and disease-causing pathogens. Recently, environmental cleaning and disinfection have become important as well as the evaluation of cleanliness.

Cleaning of frequently contacted environmental surfaces, monitoring and verifying the cleaning results are important for patient safety. The effectiveness of environmental cleaning can be assay by different methods. Visual evaluation, ATP (AdenosineTriphosphate) measurement, protein tests and fluoroscan marking methods are some of them.

Evaluation of the patient unit cleanup in the ICU, that is carried out after the discharge of patients with infection or colonization that would require strict contact isolation, by Fluoroscan Marking, BCA and Microbiological Sampling methods, is planned with the aim of collecting data in order to prove the efficiency and clinical employability of the new cleaning assessment method, PRO1 Micro Hygiene Monitoring System (System consisting of protein pen and device that analyzes with BCA method).
