Background We report a nosocomial outbreak caused by Burkholderia cepacia that occurred among six patients admitted in the medical and surgical intensive care unit between 04 March 2019 and 02 April 2019 in Istanbul, Turkey. Methods The outbreak investigation was launched on 11 March 2019 five days after the detection of B. cepacia in four different patients. We defined potential reservoirs and started environmental screening. We sampled the liquid solutions used in patient care activities. Pulse-field gel electrophoresis (PFGE) was performed to determine the genetic relatedness of environmental and patient samples. Results Burkholderia cepacia was isolated in tracheal aspiration cultures of six patients. Three out of six patients developed healthcare-associated pneumoniae due to B. cepacia. Environmental cultures in the ICUs revealed B. cepacia growth in 2% chlorhexidine-gluconate mouthwash solution that been used in the colonized patients as well as in samples obtained from the unused products. PFGE revealed the patient and a specific batch of chlorhexidine mouthwash solution samples had a 96% similarity. Conclusion Contamination of medical solutions used in critical patient care could cause outbreaks and should be detected early by infection control teams. Graphic abstract

Background: Hand hygiene (HH) is the most effective way to prevent health care-associated infections; however, HH compliance rates continue to be suboptimal. Purpose: To determine the effectiveness of video-assisted training and visual feedback with ultraviolet (UV) germ technology on nursing students' HH beliefs, practices, and compliance. Methods: This study used a double-blind, posttest randomized controlled design. The experimental group received training, visual feedback with UV germ technology, and instructional videos. Results: A total of 46 students were included in the study (experimental 21 and control 25). The mean score of the HH skills checklist of the experimental group was significantly higher than that of the control group (P = .0001). The HH compliance rate was also higher in the experimental group (52.62%) compared with the control group (39.1%). Conclusions:The training, visual feedback with UV germ technology, and instructional videos increased HH compliance rates in nursing students.
