Purpose. To determine and compare the perception among nurses and doctors of the roles and tasks of critical care advanced practice nurses (APNs) in order to establish standardized and formally agreed role criteria for such critical care APNs. Method. This study measured and analyzed the necessity of each of the roles and tasks of critical care APNs, as perceived by nurses and doctors, through a survey of 121 participants: 71 nurses in 7 intensive care units (ICUs) at a general hospital in Seoul, and 50 doctors who used ICUs. Data collection utilized a questionnaire of 128 questions in the following fields: direct practice (79), leadership and change agent (17), consultation and collaboration (15), education and counseling (11), and research (6). Results. Both the nurses' and the doctors' groups confirmed the necessity of critical care APNs, with doctors who frequently used ICUs indicating a particularly strong need. As for the priority of each role of critical care APNs, the nurses considered direct practice to be the most critical, followed by education and counseling, research, consultation and collaboration, and leadership and change agent. The doctors also considered direct practice to be the most critical, followed by education and counseling, consultation and collaboration, research, and leadership and change agent. There was a statistically significant difference between how the two groups regarded all the roles, except for the consultation and collaboration roles. As for the necessity of each role of critical care APNs, the nurses considered research to be the most necessary, followed by education and counseling, consultation and collaboration, leadership and change agent, and direct practice. The doctors, on the other hand, considered education and counseling to be the most necessary, followed by research, consultation and collaboration, leadership and change agent, and direct practice. The responses of the two groups to all the roles, except for education and counseling roles, were significantly different. Conclusion. Nurses and doctors have different perceptions of the roles and tasks of critical care APNs. Thus, it is necessary for the combined nursing and medical fields to reach an official agreement on a set of criteria to standardize for the roles and tasks of critical care APNs.

Purpose: The purpose of this study was to assess critical care nurses' perception, knowledge, and nursing practices regarding enteral nutrition. Methods: A descriptive study was conducted with 187 nurse participants who worked in one of the eight medical and surgical intensive care units (ICUs) from four hospitals in Korea. Data were collected using a self-administered questionnaire. Results: Although critical care nurses' perception toward enteral nutrition was high, knowledge was relatively low. The overall perception and knowledge of the nurses did not differ significantly between medical ICU and surgical ICU nurses. Perception of their own knowledge, in particular, 'nutritional goal' was lower for medical ICU nurses compared to surgical ICU nurses. Nurses also had limited knowledge about the significance of enteral nutrition, confirmation of feeding tube location, and nutritional requirements for ICU patients. They inadequately performed the following: changing the feeding tube every 24 hours, inspecting nostrils daily, and adjusting feeding schedule if feeding was stopped. Conclusion: Our results indicate that ICU nurses need up-to-date information about enteral nutrition. Based on the improved perception and knowledge, nursing practice activities with regard to enteral nutrition should be emphasized to enable nurses to provide optimal nutrition for ICU patients.

Purpose: This study was aimed to investigate the colony counts by different disinfecting processes and duration of the operation for humidifiers in an intensive care unit (ICU) in Busan. Method: The four steps of disinfecting process were taken with four different humidifiers according to the use of disinfectant (1:100 $Deconex^{(R)}$ 50FF/nothing) and refilling water (tap water/distilled water). First, the colony counts using water sample from wick was conducted at 0 hr, 24 hr, and 48 hr respectively after turning on the humidifiers. Next, the colony counts using waterdrop from the outlet was done at 0 hr, 24 hr, 48 hr, and 72 hr respectively after turning on the humidifiers. Result: No colony was counted after disinfecting with 1:100 $Deconex^{(R)}$ 50FF until 72 hr after turning on the humidifiers. However, without disinfecting with $Deconex^{(R)}$ 50FF, the colony count was increased in the humidifiers from 24 hr after turning on the humidifiers. The result was the same regardless of the refilling water. Conclusion: According to the results, the study found that disinfection of humidifiers in the ICUs with 1:100 $Deconex^{(R)}$ 50FF every 72 hr is effective to remove general bacteria.

Purpose: This study aimed to investigate the effect of a video-based enteral nutrition education program using QR codes on the perception, knowledge, and performance of enteral nutrition for intensive care unit (ICU) nurses. Methods: This was a quasi-experimental study with a nonequivalent control group pre- and post-test design. The participants were nurses working at six ICUs within a single university hospital, with 55 nurses in the experimental group and 55 nurses in the control group. The video-based enteral nutrition education program using QR codes was repeated three times to the experimental group. Results: There was a statistically significant pre-post difference in perceptions between the two groups (Z = -4.04, p < .001) with 2.00 points (± 5.57) for the control group and 7.89 points (± 7.95) for the experimental group, in knowledge (Z = -7.48, p < .001) with 0.02 points (± 1.91) for the control and 4.18 points (± 2.33) for the experimental, and in performance (Z = -2.20, p = .028) with 0.06 points (± 3.96) for the control and 2.00 points (± 5.14) for the experimental. Conclusion: The video-based enteral nutrition education program using QR codes was effective in improving the perceptions, knowledge, and performance of enteral nutrition among ICU nurses. This enteral nutrition education program using QR codes in clinical education can contribute to evidence-based nursing practice by improving perceptions and knowledge of enteral nutrition.

Purpose: The purpose of this study was to identify levels of knowledge, perception, and practice of eye care as part of nursing care in the ICU. Method: A descriptive, cross-sectional study design was used. The participants in this study were 269 registered nurses working in the ICUs of five university hospitals in Seoul, Korea. Between November 2005 and December 2005, data were collected using a semi-structured questionnaire developed by the researchers, and analyzed using the SPSS Program. Results: In general, levels of knowledge of nursing care for the eyes were moderate among ICU nurses, but levels of perception of nursing care for the eyes were very high. Of the respondents, 61.7% reported that they would consult a doctor whenever they found an eye problem. Only 42.4% nurses answered that they provide eye care as part of the daily routine and 43.9% nurses responded that they cleanse the eye lids with wet saline gauze. In regression analysis, the practice of eye care as part of nursing was significantly influenced by perception of nursing care for the eyes, and knowledge of interventions for nursing care for the eyes. Conclusion: These results suggest that education on care of the eyes for ICU nurses and the development of a standardized eye care protocol should be done to improve quality of nursing care in the ICU.

Background: Carbapenem-resistance is rapidly evolving among the pathogenic microbes in intensive care units (ICUs). This study aimed to determine annual trend of carbapenem-resistance in the ICU for 4 years, since the opening of a university-affiliated hospital in South Korea. Methods: From 2005 to 2008, microbial samples from consecutive 6,772 patients were screened in the ICU. Three hundred and ninety-seven patients (5.9%) and their first isolates of carbapenem-resistant pathogens were analyzed. Results: The percentage of patients infected with carbapenem-resistant organisms increased constantly during the initial three years (2.3% in 2005, 6.2% in 2006, 7.8% in 2007), then it declined to 6.5% in 2008. Acute Physiology and Chronic Health Evaluation (APACHE) III score at admission was $58.0{\pm}23.5$, the median length of the ICU stay was 37 days, and the mortality rate was 37.5%. The sampling sites were endotracheal suction (67%), catheterized urine (17%), wound (6%) and others (10%). Bacteria with carbapenem-resistance were Pseudomonas aeruginosa (247 isolates, 62%), Acinetobacter baumannii (117 isolates, 30%), Enterobacteriaceae (12 isolates, 3%), and others (21, 5%). Of note, peak isolation of carbapenem-resistant microorganisms in medical ICU was followed by the same epidemic at surgical ICU. Conclusion: Taken together, carbapenem-resistant pathogens are of growing concern in the ICU.

Purpose : This study aimed to present the incidence of pressure ulcers and identify different associated factors according to the time of occurrence of pressure ulcers in intensive care unit (ICU) patients. Methods : The participants were 313 patients who reported pressure ulcers among 2,908 patients in ICUs at a large tertiary hospital in Gyeonggi-do. Among them, 220 patients (70.3%) had a pressure ulcer before admission, and 93 patients (29.7%) reported newly developed pressure ulcers after admission to the ICU. Data were collected between August 2018 and April 2019. Along with the time of occurrence and characteristics of pressure ulcers, diverse associated factors were gathered through electronic medical records. Data were analyzed using descriptive statistics, independent t-tests, and 𝑥²-tests. Results : Different risk factors associated with pressure ulcers in ICU patients according to the time of occurrence were main diagnosis, score of acute physiology and chronic health evaluation, score of Richmond agitation sedation scale, level of consciousness, administered sedatives, use of a ventilator, insertion of a feeding tube, and the duration of fasting period. Conclusion : Based on the results of this study, healthcare providers, especially ICU nurses, should try to detect early signs and symptoms of pressure ulcers, taking into account the derived factors associated with pressure ulcers in ICU patients. Practical intervention programs and strategies considering the factors associated with pressure ulcers must be developed to prevent and alleviate such ulcers in ICU patients in the future.
