Background: Hypercalcemia is an important metabolic emergency condition in cancer patients. Bisphosphonate is the treatment of choice for hypercalcemia, whereas calcitonin and hydration with furosemide are recommended for acute supportive therapy. However, data regarding real-world treatment patterns and outcomes of pharmacological treatments are limited. Therefore, we aimed to investigate the treatment patterns and clinical outcomes of hypercalcemia treatment in solid tumor patients. Methods: Electronic medical records of 123 adults with solid cancers and albumin-corrected calcium levels >10.5 mg/dL or ionized calcium levels >1.35 mmol/L were reviewed. We retrospectively analyzed the pharmacological treatment and recovery rate according to the severity of hypercalcemia. Results: A total of 177 cases were identified, of which 49 were not treated and 30 were treated with hydration only. In moderate-to-severe cases, 86.5% received pharmacological treatment. Thirty-four cases (19.2%) were treated with bisphosphonate alone and 58 cases (32.8%) were treated with bisphosphonate and calcitonin. In mild hypercalcemia cases, the recovery rate was higher for those receiving hydration only or pharmacological treatment (79.7%) than for those receiving no treatment (61.4%, p = 0.041). Most moderate-to-severe cases were treated with medication and of those treated, 56.3% recovered. The recovery rate was lower in those treated with bisphosphonate alone (38.2%) than in those who underwent calcitonin combination treatment (73.7%, p = 0.001). Conclusions: Bisphosphonate combined with calcitonin was found to be more effective than bisphosphonate alone for the treatment of moderate-to-severe hypercalcemia. Considering the current shortage of calcitonin, further efforts are required to ensure its stable supply.

With growing interest in novel digital healthcare devices, such as artificial intelligence (AI) software for medical diagnosis and prediction, and their potential impacts on healthcare, discussions have taken place regarding the regulatory approval, coverage, and clinical implementation of these devices. Despite their potential, 'digital exceptionalism' (i.e., skipping the rigorous clinical validation of such digital tools) is creating significant concerns for patients and healthcare stakeholders. This white paper presents the positions of the Korean Society of Radiology, a leader in medical imaging and digital medicine, on the clinical validation, regulatory approval, coverage decisions, and clinical implementation of novel digital healthcare devices, especially AI software for medical diagnosis and prediction, and explains the scientific principles underlying those positions. Mere regulatory approval by the Food and Drug Administration of Korea, the United States, or other countries should be distinguished from coverage decisions and widespread clinical implementation, as regulatory approval only indicates that a digital tool is allowed for use in patients, not that the device is beneficial or recommended for patient care. Coverage or widespread clinical adoption of AI software tools should require a thorough clinical validation of safety, high accuracy proven by robust external validation, documented benefits for patient outcomes, and cost-effectiveness. The Korean Society of Radiology puts patients first when considering novel digital healthcare tools, and as an impartial professional organization that follows scientific principles and evidence, strives to provide correct information to the public, make reasonable policy suggestions, and build collaborative partnerships with industry and government for the good of our patients.

Purpose: This study was conducted to evaluate the performance following the application of the pilot program for the education nurse system of the Ministry of Health and Welfare in a medical institution. Methods: This study was employed a non-homogeneous comparative group design by comparing new nurses who entered the medical institution after the pilot project from December 2019 to April 2020 with new nurses who entered before the pilot project during the same period. Satisfaction, academic achievement, job adaptation, personal turnover within one year, and patient safety incident rate were investigated as performance indicators. Results: After the pilot project, the overall satisfaction among new nurses, preceptors, and fellow nurses increased, but there were no significant changes in academic achievement and job adaptation in new nurses. The personal turnover rate decreased from 15.6% to 9.1%, and the patient safety incident rate also decreased from 26.3% to 15.7%. Also, the preceptor overtime also decreased from 3.67 to 0.66 hours. Conclusion: The performance of the pilot project for the education nurse system was related to improvements in satisfaction, turnover rate of new nurses, patient safety incident rate, and preceptor overtime. Above all long-term monitoring of each performance indicator is necessary through the continuation of the education nurse system of the Ministry of Health and Welfare.

Purpose: This study was to develop a factor-type patient classification system for general nursing unit based on nursing needs (KPCS; Korean patient classification system for nurses). Method: We reviewed workload management system for nurses(WMSN) of Walter Reed Medical Center, Korean patient classification system for ICU, and nursing activities in nursing records and developed the first version of KPCS. The final version KPCS was evaluated via validity and reliability verifications based on panel discussions and data from 800 patient classifications. Content validity was performed by Delphi method and concurrent validity was verified by the correlation of two tools (r=.71). Construct validity was also tested by medical department (p<.001), patient type (p<.001), and nurse intuition (p<.001). These verifications were performed from April to October, 2008. Results: The KPCS has 75 items in classifying 50 nursing activities, and categorized into 12 different nursing area (measuring vital sign, monitoring, respiratory treatment, hygiene, diet, excretion, movement, examination, medication, treatment, special treatment, and education/emotional support). Conclusion: The findings of the study showed sound reliability and validity of KPCS based on nursing needs. Further study is mandated to refine the system and to develop index score to estimate the necessary number of nurses for adequate care.

신생아 황달의 주요 원인인 담도폐쇄증은 Kasai portoenterostomy가 기본적인 치료 술식이다. 수술 이후 다양한 합병증이 발생할 수 있는데 portoenterostomy를 통해 발생하는 상행성 담도염이 가장 흔하다. 성공적인 Kasai portoenterostomy 후에도 간 섬유화가 진행할 수 있어 이로 인한 간경화, 문맥 고혈압으로 인한 합병증이 많은 경우에서 발생하게 된다. 합병증이 조절되지 않거나 진행성 고빌리루빈혈증이 있는 경우 간이식을 시행하게 된다. Kasai portoenterostomy 이후 합병증 확인 및 장기 생존 환자의 추적 검사로 다양한 영상 진단이 주요 역할을 하고 있다. 또한 간이식이 필요한 경우 이식 전후로 공여자 및 수혜자 모두에서 수술 금기 확인 및 합병증 조기 발견을 위해 영상 검사들이 중요한 역할을 한다. 초음파 검사가 추적 관찰에 가장 먼저 사용되는 유용한 검사이며 추가적으로 CT 및 MRI를 통해 진단에 도움을 받을 수 있다.

Technological advances in contemporary medicine has discovered the causes of countless diseases and recorded a noticeable medical performance. As technology develops, the role of hospitals is expanding to include disease prevention of inpatients, on top of their fundamental role of treating diseases. Recently, hospitals are becoming more influential as they create environments to provide comfort and stability to patients. In this regard, contemporary hospitals are increasingly shifting their focus to create a patient-centric environment as well as develop into humanistic establishments. The same goes to dentists, as well. Since inpatients often have fear and frustration over treatment, hospitals should figure out the environmental factors that are more effective and relaxing for patients and design medical services to provide them. The patients' movement and spaces during their treatment were categorized by stages and collected for gazing information using eye tracking. It analyzed users' gaze information according to Heatmap analysis of distribution and frequency and was determined the presence or absence of stimuli on the components of space. This research is an advanced research to study and enhance treatment environment based on the analysis of patients' gazes. It attempted to create an opportunity to get closer to patient-centric environment by understanding the stimulants and obstacles and controlling the background settings.

Purpose: This study was performed to verify reliability and validity of Korean Patient Classification System for nurses(KPCS-1), to estimate nursing time conversion index, and to classify patients into groups according to KPCS-1 scores. Methods: KPCS-1 was revised from KPCS by a professional review team. Interrater reliability and construct validity of KPCS-1 were verified by data from 433 patients. Direct and indirect nursing time of 204 patients were measured by stopwatch observation and self reports for 24 hours. Nursing time conversion index was calculated. Results: KPCS-1 consisted of 12 area, 50 nursing activities, and 73 items. The interrater reliability was tested between two nurse group (r=.88, p<.001) and construct validity was verified according to medical department (F=10.97, p<.001) and patient pattern (F=5.54, p=.001). The correlation of nursing time and classification score was also statistically significant (r=.56, p<.001). The nursing time conversion index was 9.03 minutes per 1 classification score. The patients were classified into 4 groups by the classification scores. Conclusion: KPCS-1 can be a useful factor type patient classification system for general ward. Further study is needed to evaluate validity and reliability for refining KPCS-1 and to develop ways connecting the scores with nursing outcomes.
