We evaluate the influence of MR contrast agent on positron emission tomography (PET) image using phantom, animal and human studies. Phantom consisted of 15 solutions with the mixture of various concentrations of Gd-based MR contrast agent and fixed activity of [18F]FDG. Animal study was performed using rabbit and two kinds of MR contrast agents. After injecting contrast agent, CT or MRI scanning was performed at 1, 2, 5, 10, and 20 minutes. PET image was obtained using clinical PET/CT scan, and attenuation correction was performed using the all CT images. The values of HU, PET activity and MRI intensity were obtained from ROIs in each phantom and organ regions. In clinical study, patients (n=20) with breast cancer underwent sequential acquisitions of early [18F]FDG PET/CT, MRI and delayed PET/CT. In phantom study, as the concentration increased, the CT attenuation and PET activity also increased. However, there was no relationship between the PET activity and the concentration in the clinical dose range of contrast agent. In animal study, change of PET activity was not significant at all time point of CT scan both MR contrast agents. There was no significant change of HU between early and delayed CT, except for kidney. Early and delayed SUV in tumor and liver showed significant increase and decrease, respectively (P<0.05). Under the condition of most clinical study (< 0.2 mM), MR contrast agent did not influence on PET image quantitation. J Radiopharm Mol Probes 1(2):130-136, 2015

Purpose: This study assessed the status of the Development and Utilization of critical pathways (CP) in South Korea. Methods: We surveyed 195 hospitals obtained on the Korean Hospital Association website. Data were collected using structured questionnaires for staff members in charge of CP management personnel in these hospitals. The questionnaire included CP developed by the institutions, the coverage rates and completion rates of CP in the current year, and management indicators related to CP. The questionnaire also included CP support systems and content within the institutions and questions regarding the advantages of CP utilization and obstacles associated with the CP development process. Results: Analysis of the responses from 70 hospitals (35.9% response rate) showed that a total of 1,370 CP sets were developed. The number of CP related to surgery departments was 365 (26.6%), and CP related to surgery and procedure was 1,093 (79.8%), respectively. The CP coverage rate was the most frequently used indicator to monitor the effect of CP (97.1%), followed by the completion rate (90.0%) and the length of stay in hospital (61.4%). CP managers reported that CP were highly useful for communication (3.39±0.493) and accurate information provision (3.39±0.491). The perception that CP violated doctors’ autonomy in treatment was relatively low (2.87±0.645). Conclusion: It is necessary to establish an infrastructure in hospitals for CP. CP can facilitate communication and provide accurate information.

Purpose: The purpose of this study was to develop and validate the Psychiatric Inpatient Classification System (PICS) based on nursing care needs of psychiatric inpatients. Methods: The preliminary items of the PICS based on the Korean Patients Classification System-1 (KPCS-1) were revised through literature review and interviews with psychiatric nurses. Content validity was assessed by 11 psychiatric nursing experts. In a convenience sample of 154 psychiatric inpatients, nurses reported nursing activities performed for their patients using the PICS. Criterion validity of the PICS was evaluated by testing correlation between the PICS and the Subjective Patient Classification (SPC). To identify groups of patients, the cluster analysis was performed with the PICS as a cluster variable, and cluster analysis was used. Results: The final PICS comprised 12 nursing areas, 61 nursing activities, and 104 items. Significant correlation between the PICS and the SPC showed criterion validity of the PICS. Conclusion: Results suggest a patient classification system based on psychiatric nursing needs. This will improve the quality of psychiatric nursing by providing substantial data on an appropriate ratio of psychiatric nursing staffing.

오인옥,남경아 한국정신간호학회 2018 정신간호학회지 Vol.27 No.4

Purpose: This study aimed to explore the essentials of psychiatric and mental health nursing by identifying the care experience of the psychiatric nurses. Methods: Eleven psychiatric nurses were recruited across five geographical areas in the Korea. Data were collected using semi-structured interviews from two focus groups, which were analyzed with an inductive content analysis. Results: Participants constructed two categories including ‘nursing tasks for the client’ and ‘nursing tasks for the organization’. Subcategories of nursing tasks for the client are ‘staying alert on crisis prevention’, ‘leading them to be real with eager and persistent will’, ‘nursing beyond role boundaries’, ‘tuning the needs of clients’ family’, ‘taking journey with clients’ personal life history’, and ‘doing invisible but recognizable nursing’. Subcategories of nursing tasks for the organization are ‘working as a responsible team member’, ‘integrating team competencies at the center of team’, and ‘balancing protection and control’. Conclusion: Psychiatric nurses played professional and holistic care roles for the clients, and managerial roles for the organizations. This study provides essential data for defining psychiatric nursing and estimating the appropriate ratio of psychiatric nursing staffing.

Purpose: The purpose of this study was to determine the effect of preoperative guidance and operating room environment experience using virtual reality on increasing satisfaction with information and reducing anxiety in preoperative patients undergoing general anesthesia and local anesthesia. Methods: A non-equivalent control group quasi-experimental design was employed. The participants were 80 surgical patients from 4 wards (40 experimental group and 40 control group) of the general hospital located in Gyeonggi-do. Data collection was conducted from June to November 2023 after completing the control group survey in January 2023. Data were analyzed using Chi-square, t-test, and Mann-Whitney U test using SPSS 23.0 program. Results: Satisfaction with preoperative information was higher in the experimental group than that of the control group. Additionally, anxiety related to surgery in the experimental group was significantly lower than that of the control group. The preoperative state anxiety score in the experimental group was not significantly lower than that of the control group. Conclusions: These results suggest that providing patient education and information using virtual reality technology can not only alleviate patients' anxiety related to surgery, but also have the potential to be used as an effective intervention to improve positive patient experiences.
