摘要

The risk of healthcare-associated infection is associated with being in the intensive care unit (ICU), undergoing surgery, and invasive procedures. Although not all catheter-associated urinary tract infections and bloodstream infections can be prevented, it is believed that a large number could be avoided by the proper management of patients' care with invasive devices. The purpose of the study to investigate the influence of patients' care with invasive devices (urinary catheters and peripheral vein catheters) on the risk of healthcare-associated infections. Quantitative and qualitative research methods such as questionnaire, clinically structured empirical plan and microbiological tests was used in the ICUs and in the surgical units of multi-profile hospitals of Latvia. By means of microbiological investigation the contamination level of the ICUs and surgical units was determined: a) using a Count-Tact applicator and a culture medium specially selected for this method, b) using the swab method for the microbiological contamination of the equipment and nurses' hands, and c) using the catheter sedimentation method for the microbial contamination of the invasive devices. In total were analysed 177 microbiological samples and 45 observation objects. Results suggested that a common problem in ICUs and in surgical units is the lack of unified nursing protocols on performing invasive procedures. There was excessive workload of nurses working in ICUs and in surgical units. Results showed disregard for basic principles of hand hygiene and aseptic mistakes during patients' care with invasive devices. Microbiological investigations showed a high level of bio-contamination on the nurses' hands during invasive procedures and medium to high levels of bio-contamination were discovered on patient's changed bed sheets as well as in nurses' hair and their workwear. Mentioned factors influence the patients care with invasive devices and induce risk for HAIs.
