목 적 : 집중 치료를 받고 있는 환자들에서 MDR-HAI이 전세계적으로 중요한 문제로 인식되고 있다. 그러나 이와 관련하여 소아 환자들을 대상으로 한 연구는 성인에 비해 상대적으로 부족하다. 본 연구에서는 단일 대학병원 중환자실에 입원한 소아환자를 대상으로 MDR-HAI의 발생률과 연관인자를 알아보고자 하였다. 방 법: 2009년 1월부터 2010년 12월까지 본원 환자실에서 3일 이상 입원치료 하였던 135명의 소아 환자를 대상으로 입원기록을 후향적으로 검토하였다. 원내감염을 MDR-HAI과 non-MDR-HAI의 두 군으로 나누어 각각 임상적 특징과 여러 연관인자들을 비교하였다. 결 과: 39명의 환자에서 45례의 중환자실내 원내감염이 발생하였다. 원내감염의 발생률은 중환자실 재원 1,000일당 47.7이었다. 45례 원내감염 중 36례(80.0%)가 다제 내성균에 의한 감염이었다. A. baumannii는 MDR-HAI군에서 더 흔하게 검출되었다(54.5% vs. 8.3%; P=0.007). 중환자실 입원 적응증 중 내과적 질환, 인공 호흡기 치료, 도뇨관 삽입, 이전 광범위 항생제 사용은 MDR-HAI군에서 통계적으로 유의하게 높았다. 회귀분석 결과 이전 광범위 항생제 사용만이 MDR-HAI의 독립적 위험인자였다. 결 론 : 중환자실내 원내감염의 발생률은 이전에 보고된 것보다 높았으며, 이전 광범위 항생제 사용이 MDR-HAI의 독립적 위험인자였다. 향후 중환자실에 입원한 소아 환자에게 발생한 MDR-HAI의 정확한 특징을 확인하기 위해 추가적인 연구가 필요할 것으로 생각된다.

배 경 : 중환자실에서 발열은 가장 흔한 임상 상황이며 그 원인을 감염성 또는 비감염성으로 감별하는 것은 적절한 치료와 예후 측면에서 매우 중요하다. Procalcitonin(PCT)는 최근 여러 감염 질환의 뛰어난 표식자로 보고되고 있다. 연구자 등은 중환자실 발열 환자에서 혈청 PCT의 측정이 감염성과 비감염성 원인을 감별하는 데 도움이 되는지 알아보기 위해 연구를 시행하였다. 방 법 : 2005년 3월부터 8월까지 내과 중환자실에서 치료받은 환자 중 $38^{\circ}C$ 이상의 발열이 있는 환자를 대상으로 백혈구, CRP, PCT, IL-6, $TNF-{\alpha}$를 측정하였고 원인을 규명하기 위한 검사를 시행하였다. 감염성과 비감염성 원인의 감별은 배양 검사 결과와 임상적인 경과에 의존해 판단하였다. 감염성 발열 환자, 비감염성 발열 환자, 발열이 없는 중환자 및 건강 성인에서 각각의 값을 비교하였다. 결 과 : 1) 총 42명의 환자를 대상으로 46 예의 발열에 대해 평가하였다. 감염성으로 생각된 경우는 26 예, 비감염성은 13 예, 7예는 원인이 명확하지 않았다. 2) 감염성과 비감염성 원인의 발열의 정도, 백혈구 수, CRP, IL-6, $TNF-{\alpha}$는 유의한 차이가 없었다. 3) 감염성 원인과 비감염성 원인의 혈청 PCT는 각각 $15.1{\pm}32.57ng/mL$, $2.68{\pm}3.63ng/mL$로 감염성 원인이 높았으나 통계적인 유의성은 없었다(p=0.06). 4) 발열이 있는 환자의 혈청 PCT은 $10.94{\pm}27.15ng/mL$로, 발열이 없는 중환자의 $0.45{\pm}0.49ng/mL$에 비해 의미 있게 높았다(p=0.02). 결 론 : 중환자실 발열 환자에서 혈청 PCT의 측정은 감염성 원인과 비감염성 원인을 감별하는 데 도움이 되지 않을 것으로 사료된다.

Purpose : This study aimed to develop an in-depth and comprehensive understanding of the experiences of critical care nurses caring for dying patients. Method : Eleven critical care nurses with experience in caring for dying patients were recruited from four tertiary hospitals. Semi-structured face-to-face interviews were conducted between November 2016 and March 2017. The transcribed data were analyzed using qualitative content analysis to identify major themes and sub-themes that represented the experiences of critical care nurses. Results : The following six themes, and twelve sub-themes, were identified: (1) the gap between expectation and reality, (2) a distorted meaning of death, (3) repeated emotional pain and stress, (4) finding a solution alone, (5) sublimation into mission and calling, and (6) integration into one's own life. Conclusion : This study found that critical care nurses experience various psychological difficulties while caring for dying patients, and they made efforts on their own to overcome them. These findings are expected to inform the development of specialized programs to support critical care nurses to tackle these challenges, create guidelines on caring for dying patients, and help promote death education.

Purpose: This study was conducted to identify changes in limb circumferences among patients admitted to the intensive care unit (ICU) and related factors. Methods: We conducted a prospective observational study with 27 patients from 3 ICUs at a university hospital located in B city of Korea, from September 1 to October 30, 2015. The circumferences of the left and right upper arms, thighs, and lower legs were measured on the first, third, fifth, and seventh days of ICU admission. Information on the related factors was collected from the medical records. The data were analyzed using a linear mixed model method. Results: The limbs circumferences significantly reduced from day 3, and the changes continued till day 7. These changes were related to the gender of the subjects, restraints application, use of steroids, and continuous renal replacement therapy. Conclusions: Based on the above results, it can be concluded that ICU-acquired weakness begins before the third day of admission. Thus, early mobilization protocols for ICU patients need to be developed and implemented in order to improve long-term outcomes.

Purpose : To explore the person-centered care (PCC) experienced by critical patients. Method : This qualitative study deductively examined the attributes of the PCC model proposed by Jakimowicz and Perry. The participants were 16 patients who were recently discharged from intensive care units at a university hospital. Data were collected through in-depth interviews and were analyzed using the deductive method of content analysis. Results : A total of 4 categories, 16 subcategories, and 33 codes were generated from 171 meaningful statements. The final 4 categories were "compassionate presence," "professional interaction," "outstanding competency," and "patient identity." These were consistent with the main attributes of Jakimowicz and Perry's model. However, most of the codes belonged to the "compassionate presence" and "patient identity" categories. Among the attributes of the model, "continuity of nursing," "therapeutic relationship," "expert knowledge," "clinical knowledge," "evidence-based intervention," and "patient's rights" were not derived as codes. Conclusion : These findings deepen the understanding of the PCC model from the patient's point of view. The main attributes of PCC identified in the current study can be applied to the development of practical guidelines for intensive care nursing. In addition, we recommend the development of a PCC measurement tool for critical care patients.

Purpose: To investigate the post-intensive care syndrome (PICS) and to analyze the factors affecting the quality of life (QoL) of survivors of critical illness. Methods: Subjects were 114 outpatients who had been discharged from intensive care units of a university hospital in B city, Korea. From July 30 through September 30, 2015, PICS was assessed using the Korean Montreal Cognitive Assessment, Hospital Anxiety-Depression Scale, Korean Instrumental/Activities of Daily Living (K-I/ADL) index, and handwriting transformation, while physical and mental health-related QoL was measured using the SF-12. Results: Of the subjects, 39.5% were screened for mild cognitive disorder and 23.7% experienced handwriting transformation after discharge. Multiple regression analysis revealed that restraint application, current job, time of ${\geq}36$ months after discharge, depression, anxiety, and handwriting transformation accounted for 40.9% of the physical health-related QoL, and depression, anxiety and experience of delirium accounted for 62.4% of the mental health-related QoL. Conclusions: It is necessary to make efforts to reduce restraint application in intensive care units and prevent the occurrence of delirium, with the objective of reducing PICS and improving the QoL of critical illness survivors.

Purpose : This study aimed to identify the prevalence and risk factors of cognitive impairment in survivors discharged from the intensive care unit (ICU). Methods : This secondary analysis study utilized data from a multicenter prospective cohort of post-ICU patients. We analyzed the data of 175 patients enrolled in the primary cohort who completed the cognitive function evaluation three months after ICU discharge. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) scale. The cut-off points for cognitive impairment were < 23 for face-to-face evaluation and < 18 for telephone evaluation. Results : The prevalence of cognitive impairment three months after ICU discharge was 32.6%. Significant risk factors for cognitive impairment were age ≥ 60 years (OR=10.52, 95% CI=3.65~30.33, p<.001), education < high school graduation (OR=2.53, 95% CI=1.07~6.01, p=.035), unplanned ICU admission (OR=4.01, 95% CI=1.45-11.14, p=.008), and delirium in the ICU (OR=4.33, 95% CI=1.08-17.23, p=.038). Conclusion : ICU nurses should use preemptive strategies to reduce post-ICU cognitive impairment of patients with risk factors. It is necessary to frequently assess and detect early delirium in critically ill patients, while attempting various non-pharmacological interventions.

Purpose : This study aimed to investigate the characteristics and risk factors associated with pressure injuries related to medical devices among patients admitted to the intensive care unit (ICU). Method : A retrospective study analyzed data from 462 ICU patients. Statistical analyses, including independent t-tests, Fisher's exact tests, and logistic regression were performed to analyze the data. Results : Among the 154 subjects, there were a total of 198 medical device-related pressure injuries (MDRPI). Stage 2 and deep tissue pressure injuries were the most frequent. MDRPI occurred most frequently on the face, with nasogastric tubes being its leading cause, followed by endotracheal tubes. The risk factors for MDRPI included male sex (odds ratio [OR]=1.78, 95% confidence interval [CI]=1.12-2.83), department at the time of ICU admission (OR=4.29, 95% CI=2.01-9.15), post-surgery ICU admission (OR=0.43, 95% CI=0.25-0.73), application of extracorporeal membrane oxygenation machines (OR=2.72, 95% CI=1.06-6.95), number of medical devices (OR=1.16, 95% CI=1.05-1.30), inotropic drug administration (OR=2.33, 95% CI=1.19-4.60), and sedative use (OR=2.53, 95% CI=1.17-5.45). Conclusion : These results enable the determination of the characteristics and risk factors associated with MDRPI. It is crucial to acknowledge the risk factors for MDRPI in ICU patients and establish a prevention strategy.

Purpose : This study sought to explore intensive care unit (ICU) nurses' perceptions regarding the disclosure of patient safety incidents (DPSI) and identify the relationship between the perception of DPSI and communication barriers. Methods : This study used a descriptive research design. A total of 110 ICU nurses from a tertiary hospital were surveyed online between September 14 and October 5, 2022. The mean DPSI score ranged between 1.0 and 4.0, with a higher score indicating a higher perception of DPSI. Results : The mean score for ICU nurses' perceptions of DPSI was 2.92 (SD=0.37). Among the characteristics of ICU nurses, differences were observed in perceptions of DPSI according to gender, age, total work experience, and ICU work experience. Communication barriers among ICU nurses were negatively correlated with negative results as a sub-factor of perceptions of DPSI. Ambiguity in the nurse's position, lack of confidence, differences in perspectives with patients, and inadequate nurse-patient relationships as sub-factors of communication barriers exhibited a negative correlation with negative results as a sub-factor of perceptions of DPSI. Conclusions : ICU nurses' perceptions of DPSI and the sub-factors related to communication barriers are negatively related to DPSI. To improve ICU nurses' perceptions, open and non-punitive circumstances, staff education, practical guidelines, and support systems are required.
