Aprepitant is a substance P/neurokinin-1 (NK1)-receptor antagonist that was approved in 2003 for prevention of CINV. In addition, updated anti-emetic guidelines that include the aprepitant regimen have been published by NCCN and ASCO. However there is scarce clinical data in Korea. The prospective study was performed to evaluate the prevention of high dose cisplatin induced nausea and vomiting in all patients who started high-dose cisplatin-based chemotherapy at our hospital. We checked the nausea severity and vomiting episodes by calling patients within 4 to 5 days after chemotherapy. The retrospective study was performed to compare the prevention of CINV in solid tumor patients who switched their anti-emesis regimen from the standard regimen to the aprepitant regimen. In aprepitant regimen, aprepitant was added to the same anti-emetic regimen used during previous cycles. We checked the nausea, vomiting grades and adverse events in electronic medical records (EMR). In prospective study, 195 patients were included in the analysis. 88.2% of patients achieved a complete response (no emesis and no rescue therapy). In retrospective study, 54 patients were reviewed. With aprepitant regimen, nausea and vomiting grades were improved in 22 patients (40.7%) and in 9 patients (16.7%), respectively. Compared with standard regimen, addition of aprepitant provided superior prevention against CINV in Korean patients receiving highly emetogenic cisplatin-based chemotherapy. Moreover, aprepitant significantly prevented CINV in patients who received the standard regimen to prevent CINV in previous chemotherapy cycles.

Purpose: We investigated the association between defoliant exposure and survival to discharge after out-of-hospital cardiac arrest. Methods: This is a retrospective case-control study based on the cardiopulmonary resuscitation (CPR) registry. The electronic medical records of out-of-hospital cardiac arrest victims from 6/9/2008 to 12/31/2016 were analyzed statistically. The case patients group had a history of defoliant exposure while the control group did not. Among the 401 victims studied, a total of 110 patients were male out-of-hospital cardiac arrest patients. Baseline characteristics and the parameters involved in cardiac arrest were analyzed and compared between the two groups after propensity score matching. The primary outcome was survival to discharge, and secondary outcomes were sustained return of spontaneous circulation (ROSC) and survival to admission. Results: After propensity score matching a total of 50 patients (case=25, control=25) were analyzed. Primary outcome (survival to discharge) was not significantly different between case and control groups [(OR, 1.759; 95% C.I., 0.491-6.309) and (OR, 1.842; 95% C.I., 0.515-6.593), respectively]. In the subgroup analysis, there were also no significant differences between the control group and subgroups in primary and secondary outcomes according to defoliant exposure severity. Conclusion: There is no statistically significant association between defoliant exposure and survival of out-of-hospital cardiac arrest.
Purpose: The purpose of this study was to analyze the characteristics of patients who canceled their ED visits and to determine the factors that influence ED cancellation. Methods: Retrospective study that analyzed data from the electronic medical records(EMR) and Prehospital Care Reports(PCRs) of 305 patients who cancelled their appointments at a single emergency medical center over a six-month period from October 12, 2022, to April 12, 2023. Results: ED cancellations were 2.287 times higher if the patient presented to the ambulance after outpatient hours(09:00~17:00) (p=.007), and ED cancellations were 3.712 times higher if the patient presented to the ambulance under the influence of alcohol(p=.011). For patients' symptoms, medical diseases were associated with a 1.965 times increase in cancelled ED visits compared to other modes of transport (p=.005), while mental and chronic diseases were associated with a 67.3% decrease in cancelled ED visits compared to other modes of transport (OR=0.327, CI=[0.130-0.822], p=.018). symptomatic improvement was associated with a 2.482 times increase in presentations to a 119 ambulance compared to delayed waiting time(p=.022). Conclusion: Emergency medical centers should consider improving the legal system, such as increasing emergency medical care fees, to reduce the number of patients who cancel their appointments.
Background and Aim: Oxaliplatin hypersensitivity is a well-known adverse reaction but the prevalence varies and data for frequency and clinical features have not been reported for Korea. Here we evaluates the prevalence and risk factors for hypersensitivity reactions to oxaliplatin after chemotherapy. Methods: Clinical information on all patients treated with oxaliplatin was retrospectively reviewed in electronic medical records between August 2009 and July 2010 in Seoul National University Bundang Hospital. Patients who experienced hypersensitivity reactions to oxaliplatin were compared with those who did not. Results: A total of 393 patients received oxaliplatin, with 42 (10.7%) experiencing hypersensitivity reactions including three cases of anaphylaxis. Median cycle of the first hypersensitivity reaction was 8. Reactions correlated with lower dexamethasone doses. Other variables were not significant. Conclusions: The prevalence of hypersensitivity reactions was 10.7%, symptoms being mostly mild and cutaneous. Lower dexamethasone doses could be a predictor for hypersensitivity reactions to oxaliplatin.

Background: Few studies have investigated unspecified or idiopathic pain associated with COIVD-19. This study aimed to provide the incidence rates of unspecified pain and idiopathic pain in patients with COVID-19 for 90 days after COVID-19 diagnosis. Methods: A propensity score matched cohort was used, including all patients with COVID-19 in South Korea, and analyzed their electronic medical records. The control group consisted of those who had not had tests for COVID-19 at all. Unspecified pain diagnoses consisted of diagnoses related to pain included in the ICD-10 Chapter XVIII. Idiopathic pain disorders included fibromyalgia, temporomandibular joint disorders, headaches, chronic prostatitis, complex regional pain syndrome, atypical facial pain, irritable bowel syndrome, and interstitial cystitis. Results: After matching, the number of participants in each group was 7,911. For most unspecified pain, the incidences were higher in the COVID-19 group (11.7%; 95% confidence interval [CI], 11.0-12.5) than in the control group (6.5%; 95% CI, 6.0-7.1). For idiopathic pain, only the headaches had a significantly higher incidence in the COVID-19 group (6.6%; 95% CI, 6.1-7.2) than in the control group (3.7%; 95% CI, 3.3-4.1). However, using a different control group that included only patients who visited a hospital at least once for any reasons, the incidences of most unspecified and idiopathic pain were higher in the control group than in the COVID-19 group. Conclusions: Patients with COVID-19 might be at a higher risk of experiencing unspecified pain in the acute phase or after recovery compared with individuals who had not had tests for COVID-19.

Hospitals store and manage personal and health information through the electronic medical record (EMR). However, vulnerabilities and threats are increasing with the provision of various services for information sharing in hospitals. Therefore, in this paper, we propose a model to prevent personal information leakage due to the transmission of patient information in EMR. A method for granting permission to securely receive and transmit patient information from hospitals where patient medical records are stored is proposed using OAuth authorization tokens. A protocol was proposed to enable secure information delivery by applying and delivering the record access restrictions desired by the patient to the OAuth Token. OAuth Delegation Token can be delivered by writing the authority, scope, and time of destruction to view patient information.This prevents the illegal collection of patient information and prevents the leakage of personal information that may occur during the delivery process.

In addition to complying with access standards for facilities that require infection control (operating rooms, delivery rooms, intensive care units, etc.) in accordance with the 2019 Medical Care Act Enforcement Regulations, entry, exit, contact information, etc. for entry and exit, the criteria for entering and exiting special rooms of medical institutions have been revised so that records of facts are kept for one year. However, even now, the inconvenience continues due to the fact that such contents are created by hand or due to errors. For this reason, this study designed and implemented a system that provides automatic opening, closing, and accessing record storage functions for authorized users using IoT devices and UWB technology, and we expected that the convenience of the visitors and systemized access control will be possible.

Objective : The occurrence of posterior fossa teratomas in adulthood is extremely rare. In this study, we aimed to report our experience with two cases of posterior fossa mature teratoma in adults who underwent surgical resection. We also performed a systematic review of published papers available to date. Methods : We retrospectively reviewed the electronic medical records of patients who had onset of posterior fossa teratomas in adulthood at our institute between 1995 and 2020. We evaluated the clinical, radiographic, and pathological features of mature teratomas at the posterior fossa in adulthood. Furthermore, we searched the PubMed, EMBASE, and Web of Science database and reviewed published articles. Results : We found 507 articles on database review; of them, 102 were duplicates and 389 were excluded based on the inclusion criteria. Finally, 16 cases of posterior fossa from the web search and related articles. Subsequently, we added two cases that underwent surgery at our institute. We analyzed a total of 18 cases of mature teratomas. Headache was the most common (55.6%) symptom. The teratomas showed heterogeneous signals on magnetic resonance imaging. Thirteen patients (72.2%) had lesion at midline, five patients (27.8%) had calcification. Surgical resection was performed in all patients. No studies reported recurrence after resection. Conclusion : The occurrence of posterior fossa teratomas in adulthood is difficult to diagnose at the initial stage. Radiographic diagnosis alone can lead to misdiagnosis. Pathological confirmation is essential. Surgical resection is a curative option for posterior fossa teratomas in adulthood.

Objectives The aim was to find effective vectorization and classification models to predict a psychiatric diagnosis from text-based medical records. Methods Electronic medical records (n = 494) of present illness were collected retrospectively in inpatient admission notes with three diagnoses of major depressive disorder, type 1 bipolar disorder, and schizophrenia. Data were split into 400 training data and 94 independent validation data. Data were vectorized by two different models such as term frequency-inverse document frequency (TF-IDF) and Doc2vec. Machine learning models for classification including stochastic gradient descent, logistic regression, support vector classification, and deep learning (DL) were applied to predict three psychiatric diagnoses. Five-fold cross-validation was used to find an effective model. Metrics such as accuracy, precision, recall, and F1-score were measured for comparison between the models. Results Five-fold cross-validation in training data showed DL model with Doc2vec was the most effective model to predict the diagnosis (accuracy = 0.87, F1-score = 0.87). However, these metrics have been reduced in independent test data set with final working DL models (accuracy = 0.79, F1-score = 0.79), while the model of logistic regression and support vector machine with Doc2vec showed slightly better performance (accuracy = 0.80, F1-score = 0.80) than the DL models with Doc2vec and others with TF-IDF. Conclusions The current results suggest that the vectorization may have more impact on the performance of classification than the machine learning model. However, data set had a number of limitations including small sample size, imbalance among the category, and its generalizability. With this regard, the need for research with multi-sites and large samples is suggested to improve the machine learning models.
Background: The purpose of this study was to investigate the characteristics and direction of treatment for peripheral facial palsy (PFP) based on medical collaboration between Western and Korean medicine departments. Methods: There were 195 outpatients with PFP identified retrospectively by examining electronic medical records. These patients were treated with Korean and Western medicine from January 1st, 2018 to December 31st, 2018 at the Kyung Hee University hospital. Records were analyzed according to the patients' demographic characteristics and clinical features of the collaborative combined treatment. Results: According to the collaborative treatment pathway, the number of patients consulted from Western medicine departments was more than consulted from Korean department for the first time. The time taken by the Western medicine departments to consult with the patients at the Korean center for the first time was 14.9 days from the onset of symptoms. Acupuncture was the most frequently used Korean medicine treatment. The total treatment period for Korean medicine sessions and intervals were 91.9 days, 23 times and 3.6 days, respectively. When the Korean medicine center consulted with Western medicine departments, the time taken until the first consultation was 8.5 days from the onset of symptoms. Medication was the most used treatment, prescribed after 3.1 days. The most frequently used clinical test was an electromyogram, and this was performed after 20.5 days. The total treatment period, sessions and intervals were 21.2 days, 2.8 times and 5 days, respectively. Conclusion: The clinical status of collaborative treatment for PFP was determined including the timing and interval of consultation according to treatments.
