A Study on the Meal Assistance and Nutrition Knowledge of Caregivers for the Elderly in Nursing Homes

This study attempted to examine the nutrition knowledge of caregivers for the elderly and the diet-related medical treatment and dietary assistance given by them. Thus, this research is a descriptive study focusing on the current nutritional knowledge of caregivers and the dietary assistance given by them. The survey included a questionnaire (nutritional knowledge level of digestive system diseases, diabetes, cardiovascular risk, brain disease, bone disease, and meal assistance performance status) for caregivers working in nursing homes for the elderly. Self-administered questionnaires were completed by 235 caregivers between February and March 2020. The results were analyzed using the SPSS 25.0, and the significance test of each question was verified by the Friedman test and the Chi-square independence test. The number of elderly people who needed meal assistance from caregivers was 4.4 more than the average. The most common types of meal assistance were partial assistance (59.20%) and the task of when to stop eating for the elderly (58.71%). Besides, the higher nutritional knowledge level of the caregivers, the more the time spent on services related to meal assistance (P＜0.001), and the higher the meal assistance level. The disease state of the elderly was considered the most relevant (P＜0.001). Caregivers with high levels of knowledge and offering significant meal assistance were found to have received nutrition education (P＜0.001). Up to 80% of the respondents needed nutrition education, and most of them answered that they needed education on appropriate management methods for the specific disease state of the elderly (P＜0.01). Accordingly, providing nutrition education for caregivers for the elderly should be a means to improve their ability to offer meal assistance.

A patient who was diagnosed with arachnoid web due to weakness in the limb: a case report

Arachnoid web is a very rare disease that occurs when the normal flow of cerebrospinal fluid is disturbed due to abnormal formation of the arachnoid membrane in the arachnoid space. Consequently, symptoms appear in the form of various myelopathies, such as loss of strength and sensation in the upper and lower extremities, or bladder control disorders. In general, surgical treatment can be considered if symptoms are exhibited. Arachnoid web requires a high consideration of appropriate diagnosis and treatment methods. However, due to its extremely rare occurrence in actual clinical practice, it is difficult to differentiate from other diseases such as herniated intervertebral disc or subdural tumor causing spinal myelopathy. This would effectively lead to a completely different direction of treatment. To date, there have been no case reports of Arachnoid web in Korea, except for collecting and reporting the focal anterior displacement of the thoracic spine, which is a similar lesion in the spinal cord. This article therefore provides information through case reports and literature review.

Traumatic brain injury in patients aged ≥65 years versus patients aged ≥80 years: a multicenter prospective study of mortality and medical resource utilization

Objective@#This study aimed to determine whether there is a difference in mortality and medical resource utilization between geriatric (aged ≥65 years) and super-geriatric patients (aged ≥80 years) with traumatic brain injury (TBI). @*Methods@#We obtained comprehensive data (demographics, injury characteristics, injury severities, and outcomes) of geriatric and super-geriatric TBI patients from an emergency department-based injury surveillance system database from 2011 to 2016. Multivariate logistic regression analysis was performed to compare the mortality and nonroutine discharge (NRDC) status between both groups. @*Results@#Among 442,533 TBI patients, 48,624 were older than 65 years. A total of 48,446 patients (37,140 geriatric and 11,306 super-geriatric) without exclusion criteria were included in the final analysis. Both overall in-hospital mortality (adjusted odds ratio, 1.88; 95% confidence interval [CI], 1.28 to 2.74; P=0.001) and NRDC (adjusted odds ratio, 1.35; 95% CI, 1.07 to 1.71; P=0.011) were significantly higher in the super-geriatric group. In the stratified analysis, there were no significant differences in NRDC rate for all stratifications of treatment timing (emergency department vs. ward admission), but mortality remained to be significant for all stratifications. @*Conclusion@#Super-geriatric TBI patients showed a significantly higher risk-adjusted overall mortality and more inadequate medical resource utilization than did geriatric TBI patients. However, super-geriatric patients were more likely to undergo NRDC after admission; thus, further research about age-related health inequalities is needed in the treatment of super-geriatric patients.

Occupational Stress and Quality of Life in Mental Health Welfare Center Workers / 우울ㆍ조울병

Background@#This study aimed to examine the occupational stress and quality of life of mental health welfare center workers and to identify the impact of occupational stress on compassion satisfaction, burnout, and secondary traumatic stress. @*Methods@#This study included 588 employees working at 15 provincial/municipal/regional mental health welfare centers. Demographic and psychosocial factors were surveyed. Data were analyzed using independent t-test, Pearson’s correlation test, and multiple regression analysis. @*Results@#The high-risk group for occupational stress showed low compassion satisfaction, high burnout, and high secondary traumatic stress. Compassion satisfaction showed a significant negative correlation with occupational stress. Burnout and secondary traumatic stress showed a significant positive correlation with occupational stress.Occupational stress factors affecting compassion satisfaction included lack of reward (β=−0.155, p<0.001), whereas those affecting burnout included physical environment (β=0.028, p<0.01), job demand (β=0.042, p<0.001), relationship conflict (β=0.033, p<0.01), job instability (β=0.016, p<0.01), lack of reward (β=0.051, p<0.001), and occupational climate (β=0.024, p<0.01). Additionally, occupational stress factors affecting secondary traumatic stress included physical environment (β=0.063, p<0.001) and job instability (β=0.020, p<0.05). @*Conclusion@#Occupational stress had a significant impact on compassion satisfaction, burnout, and secondary traumatic stress. Therefore, active interventions against occupational stress factors are necessary to improve the quality of life of mental health welfare center workers.

Interpersonal violence epidemiology and mortality by violence victim-perpetrator relationships

OBJECTIVE: The aim of this study was to investigate the interpersonal violence (IPV) epidemiology and mortality according to the violence victim-perpetrator relationships. METHODS: A retrospective cross-sectional study was done using the comprehensive data of the emergency department (ED)-based Jeju Injury Surveillance System from all EDs in Jeju Island. The demographic characteristics of the victims, the types of perpetrators (spouse, family members, acquaintance, and stranger), injury characteristics and clinical outcomes from the injury were collected. The IPV epidemiology was reported by descriptive statistics. Multivariate Poisson regression was used to analyze the association between the mortality and violence victim-perpetrator relationships. RESULTS: Among the 23,508 violent injury patients enrolled from January 1, 2008, and December 31 of 2016, 19,879 (84.6%) were analyzed; 16 (0.08%) died at the ED. The types of perpetrators were the spouse (10.1%), family members (3.9%), acquaintances (43.4%), and strangers (42.7%). The mortality of the violence victims was increased significantly by the spouse (incidence rate ratio [IRR], 6.336; P=0.043) or family members (IRR, 11.089; P=0.016) compared to strangers. On the other hand, there was no difference between the acquaintances and strangers. CONCLUSION: The epidemiology and mortality of IPV were associated with the violence victim-perpetrator relationships. Therefore, it is necessary to develop and apply prevention programs considering these differences, particularly for intimidate/ family violence because of its high fatality.

Effect of Personalized Nutritional Counseling on the Nutritional Status of Hemodialysis Patients

This study set out to evaluate the impact of personalized nutritional counseling (PNC) on the nutritional status of hemodialysis (HD) patients. This was an intervention study for 10 months at 2 hospitals. Anthropometric, biochemical, dietary, and body composition parameters were measured at baseline and after 3 and 6 months of PNC. A total of 42 patients (23 men and 19 women) were included. Intake of dietary protein, serum albumin, and cholesterol levels had increased significantly from baseline to month 6 (p < 0.05). Among the bioelectrical impedance analysis (BIA) parameters, both the body cell mass (BCM) and the fat free mass (FFM) had significantly reduced at month 3 compared to baseline (p < 0.05). However, there was no difference between baseline and month 6. We assessed the nutritional status of the subjects using the malnutrition inflammation score (MIS), and divided them into an adequately nourished (AN) and a malnourished (MN) group at baseline. In the subgroup analysis, serum levels of albumin and cholesterol had increased significantly, particularly from baseline to month 6 in the MN group (p < 0.05). This study suggests that consecutive PNC contributed to the improvement of the protein intake, serum levels of albumin, cholesterol and to the delay of muscle wasting, which could also have a positive impact on the nutritional status, particularly in malnourished patients receiving HD treatment.

The impact of high serum bicarbonate levels on mortality in hemodialysis patients

BACKGROUND/AIMS: The optimal serum bicarbonate level is controversial for patients who are undergoing hemodialysis (HD). In this study, we analyzed the impact of serum bicarbonate levels on mortality among HD patients. METHODS: Prevalent HD patients were selected from the Clinical Research Center registry for End Stage Renal Disease cohort in Korea. Patients were categorized into quartiles according to their total carbon dioxide (tCO₂) levels: quartile 1, a tCO₂ of < 19.4 mEq/L; quartile 2, a tCO₂ of 19.4 to 21.5 mEq/L; quartile 3, a tCO₂ of 21.6 to 23.9 mEq/L; and quartile 4, a tCO₂ of ≥ 24 mEq/L. Cox regression analysis was used to calculate the adjusted hazard ratio (HR) and confidence interval (CI) for mortality. RESULTS: We included 1,159 prevalent HD patients, with a median follow-up period of 37 months. Kaplan-Meier analysis revealed that the all-cause mortality was significantly higher in patients from quartile 4, compared to those from the other quartiles (p = 0.009, log-rank test). The multivariate Cox proportional hazard model revealed that patients from quartile 4 had significantly higher risk of mortality than those from quartile 1, 2 and 3, after adjusting for the clinical variables in model 1 (HR, 1.99; 95% CI, 1.15 to 3.45; p = 0.01) and model 2 (HR, 1.82; 95% CI, 1.03 to 3.22; p = 0.04). CONCLUSIONS: Our data indicate that high serum bicarbonate levels (a tCO₂ of ≥ 24 mEq/L) were associated with increased mortality among prevalent HD patients. Further effort might be necessary in finding the cause and correcting metabolic alkalosis in the chronic HD patients with high serum bicarbonate levels.

A Study on the Dietary Intake and the Nutritional Status among the Pancreatic Cancer Surgical Patients

The adequate dietary intake is important to maintain the nutritional status of the patients after pancreatic cancer surgery. This prospective study was designed to investigate the dietary intake and the nutritional status of the patients who had pancreatic cancer surgery. Thirty-one patients (15 men, 16 women) were enrolled and measured body weight, body mass index (BMI), nutritional risk index (NRI), and Malnutrition Universal Screening Tool (MUST). Actual oral intake with nutritional impact symptoms recorded on the clinical research foam at every meal and medical information were collected from electronic medical charts. The rates of malnutrition at admission were 45.1% (14/31) and 28.9% (9/31) by NRI and MUST method, respectively, but those were increased to 87% (27/31) and 86.6% (26/31) after operation on discharge. The median values of daily intake of energy, carbohydrates, fat, and protein were 588.1 kcal, 96.0 g, 11.8 g, and 27.0 g, respectively. Most patients (n = 20, 64.5%) experienced two or more symptoms such as anorexia, abdominal bloating and early satiety. There were negative correlations between C-reactive protein (CRP) levels and the intake of total energy, protein, fat, and zinc. The rates of malnutrition were increased sharply after surgery and the dietary intake also influenced the inflammatory indicators. The results suggested that need of considering special therapeutic diets for the patients who received pancreatic surgery.

The Poisoning Information Database Covers a Large Proportion of Real Poisoning Cases in Korea

The poisoning information database (PIDB) provides clinical toxicological information on commonly encountered toxic substances in Korea. The aim of this study was to estimate the coverage rate of the PIDB by comparing the database with the distribution of toxic substances that real poisoning patients presented to 20 emergency departments. Development of the PIDB started in 2007, and the number of toxic substances increased annually from 50 to 470 substances in 2014. We retrospectively reviewed the medical records of patients with toxic exposure who visited 20 emergency departments in Korea from January to December 2013. Identified toxic substances were classified as prescription drug, agricultural chemical, household product, animal or plant, herbal drug, or other. We calculated the coverage rate of the PIDB for both the number of poisoning cases and the kinds of toxic substances. A total of 10,887 cases of intoxication among 8,145 patients was collected. The 470 substances registered in the PIDB covered 89.3% of 8,891 identified cases related to poisoning, while the same substances only covered 45.3% of the 671 kinds of identified toxic substances. According to category, 211 prescription drugs, 58 agricultural chemicals, 28 household products, and 32 animals or plants were not covered by the PIDB. This study suggested that the PIDB covered a large proportion of real poisoning cases in Korea. However, the database should be continuously extended to provide information for even rare toxic substances.

Ten Years of Results of Modified Frontalis Muscle Transfer for the Correction of Blepharoptosis

BACKGROUND: Conventional frontalis transfer may cause a range of complications. In order to overcome complications, we made modifications to the surgical technique, and compared the outcomes of patients who underwent conventional frontalis transfer with those of patients who underwent modified frontalis transfer. METHODS: We conducted a retrospective study of 48 patients (78 eyes) who underwent conventional frontalis transfer between 1991 and 2003 (group A) and 67 patients (107 eyes) who underwent modified frontalis transfer between 2004 and 2014 (group B). The frontalis transfer procedures were modified conform to the following principles. The tip of the frontalis muscle flap included soft tissue that was as thick as possible and the soft tissue on the tarsal plate was removed to the greatest extent possible. A double fold was created in cases of unilateral ptosis. In order to evaluate the objective effects of modification, preoperative and postoperative values of the marginal distance reflex 1 (MRD1), the corneal exposure area, and the decrease in eyebrow height were compared between the two groups. RESULTS: In group A, patients showed an improvement of 1.19 mm in the MRD1, a 6.31% improvement in the corneal exposure area, and a 7.82 mm decrease in eyebrow height. In group B, patients showed an improvement of 2.17 mm in the MRD1, an 8.39% improvement in the corneal exposure area, and an 11.54 mm decrease in eyebrow height. The improvements in group B were significantly greater than those in group A. CONCLUSIONS: Modified frontalis transfer showed better results than the conventional procedure and provided satisfactory outcomes.

Healthcare-Associated Pneumonia among Hospitalized Patients: Is It Different from Community Acquired Pneumonia? / 결핵및호흡기질환

BACKGROUND: The increasing number of outpatients with multidrug-resistant (MDR) pathogens has led to a new category of pneumonia, termed healthcare-associated pneumonia (HCAP). We determined the differences in etiology and outcomes between patients with HCAP and those with community-acquired pneumonia (CAP) to clarify the risk factors for HCAP mortality. METHODS: A retrospective study comparing patients with HCAP and CAP at Jeju National University Hospital. The primary outcome was 30-day mortality. RESULTS: A total of 483 patients (208 patients HCAP, 275 patients with CAP) were evaluated. Patients with HCAP were older than those with CAP (median, 74 years; interquartile range [IQR], 65-81 vs. median, 69 years; IQR, 52-78; p<0.0001). Streptococcus pneumoniae was the major pathogen in both groups, and MDR pathogens were isolated more frequently from patients with HCAP than with CAP (18.8% vs. 4.9%, p<0.0001). Initial pneumonia severity was greater in patients with HCAP than with CAP. The total 30-day mortality rate was 9.9% and was higher in patients with HCAP based on univariate analysis (16.3% vs. 5.1%; odds ratio (OR), 3.64; 95% confidence interval (CI), 1.90-6.99; p<0.0001). After adjusting for age, sex, comorbidities, and initial severity, the association between HCAP and 30-day mortality became non-significant (OR, 1.98; 95% CI, 0.94-4.18; p=0.167). CONCLUSION: HCAP was a common cause of hospital admissions and was associated with a high mortality rate. This increased mortality was related primarily to age and initial clinical vital signs, rather than combination antibiotic therapy or type of pneumonia.

The Demand and Causes of Emergency Medical Service Utilization of Visitors on Jeju Island, South Korea

PURPOSE: Providing proper emergency medical services (EMS) for domestic or international visitors to popular destinations is becoming increasingly important. Jeju Island is the most visited spot in South Korea. The number of people visiting Jeju Island has increased every year, and this was over ten times the registered population on Jeju Island. The purpose of this study was to describe EMS use behavior and to estimate demand for EMS for visitors on Jeju Island. METHODS: A retrospective observational study was conducted on Jeju Island, with 580,000 citizens. EMS is a fire-based system with a single tiered intermediate service level by a single centralized dispatch center, 29 ambulances, and approximately 130 EMS providers. We collected all ambulance run-sheet data, which included comprehensive information as well as patients' address identification, monthly number of visitors, and census data of Jeju Island from January, 2010 to December, 2012. RESULTS: Among 90,674 EMS transports, 7,209 (8%) were excluded because of unknown address of patients, and of all 83,456 (100%) patients using EMS, 9,733 (12%) were visitors and 73,732 (88%) were residents. The percentage of females was higher for visitors than residents (45% vs. 43%, p<0.001) and the mean age was younger in visitors (38+/-19 vs. 54+/-22, p<0.001). Injury was much higher for visitors than residents (63% vs. 38%, p<0.001). The estimated monthly number of EMS use per 10,000 people was 3.7 (95% CI 3.5 to 3.9) in visitors and 35.7 (95% CI 34.9 to 36.5) in residents, with a ratio of 0.104 (95% CI 0.099 to 0.108). The trend of ratio by year was not significant (p=0.630). The correlation between monthly EMS use in visitors and monthly number of unregistered population was significant (Pearson's correlation 0.844). CONCLUSION: Determining EMS use behavior and the demand of EMS in visitors is a critical task. Our results are of interest in preparing and providing the provision of EMS for visitors.

Analysis of Symptoms and Provided Services in Home-Based Cancer Patients

PURPOSE: This study was to identify symptoms and provided services of home-based cancer patients in J province. METHODS: 1,350 data poins for 167 home-based cancer patients were analyzed retrospectively. 13 symptoms and 39 service items were measured by tools for home-based cancer patients suggested by the Ministry for Health, Welfare and Family Affairs. RESULTS: The mean number of provided services was 7.4+/-9.1. The most common symptoms were fatigue, anorexia, and pain. Patients whose duration after diagnosis was over 6 years, who had metastasis, or who underwent terminal care had more symptoms. Patient education, emotional and spiritual support, and basic assessment and services were provided most often. Frequency of provided services in patients whose duration after diagnosis was over 6 years or who had metastasis was higher. Services such as symptom and pain control, or death of the patient/the bereaved were provided with more support with patients who underwent terminal care. CONCLUSION: There were some differences in provided services according to medical characteristics. Patients experienced diverse symptoms, but services regarding these symptoms seemed to be insufficient. For more effective services, cooperation between organizations for home-based cancer patients is needed to form a better management model based on the merit of each facility or patient characteristics.

Teaching Clinical Performance Examination Using Action Learning Techniques / 한국의학교육

PURPOSE: Action learning is an educational method, whereby participants study their own actions and experiences to improve performance. We aimed to study the effects and share the experiences with action learning to teach clinical performance examination (CPX). METHODS: Twenty-eight fourth-year medical students participated in this study in 2010. This course consisted of three mini-lectures, three CPX practice sessions, and an evaluation. Satisfaction and improved and deficient elements in the CPX practice session were investigated. Internal consistencies of peer evaluation and CPX scores were also investigated using Cronbach's alpha. RESULTS: Average satisfaction was 4.5 on a 5-point scale. Low Cronbach's alpha was noted for the consistencies of peer evaluation and patient-physician interaction. The most common improved element was self-confidence, followed by accustoming themselves to conversation with the standard patient. Seven students stated that they were deficient in self-confidence; other deficiencies were sympathy expression, conversation, and physical examination. CONCLUSION: CPX education using action learning by peer evaluation, generating CPX cases by themselves, repeated practices, and feedback, effected self-active learning. However, the educator and educatee must invest much time and effort. Allotting specific, scheduled times for this type of education would be more effective.

The Characteristics of Injured Pregnant Patients Visiting Seven Emergency Departments

PURPOSE: In Korea, few studies have compared outcomes in injured pregnant women to their non-pregnant counterparts. The purpose of this study is to describe the characteristics of patients injured during pregnancy who visited seven emergency departments in South Korea. METHODS: The Korean Traumatic Brain and Spine Injury Research Network (KTBSIRN) database, based on 7(emergency department) from June, 2008 to September, 2010 was used to derive data on all injured patients between 12 and 49 years of age. Data were divided into two comparison groups: pregnant and non-pregnant women. For comparison of characteristics and admission by pregnancy, we selected patients using the statistical matching method according to hospital, age, and injury mechanism after comparison with all enrolled patients. Then, members of the pregnant women group were divided into two subgroups: or =20 weeks gestational age. RESULTS: A total of 13,449 women were identified in a total of 76,596 injuries. Among them, 164(1.22%) women were pregnant. Fewer alcohol-related injuries were observed in pregnant women compared with non-pregnant women. Transportation was the leading mechanism of ED injury visits by pregnant women (52.4%). Emergency Medical Service (EMS) usage (22.0% vs. 14.6%, p<.0.008) and admission (14.0% vs. 7.9%, p<.0.001) were more common in pregnant women than in non-pregnant women. However, no significant difference was observed in injury severity scores. After matching, adjusted odds ratio of pregnancy for admission was 2.8(95% CI: 1.46~5.53). Less than half the number of pregnant women underwent an obstetric exam and non-stress test (NST) for the fetus (44.5% and 27.4%, respectively). CONCLUSION: Injured pregnant women who visited the ED were used more medical resources but showed no significant difference in injury severity. Despite maternal and fetal risk after injury, obstetric exam including fetal monitoring was not performed appropriately. Therefore, establishment of standards for injured pregnant women is needed in many EDs.

Factors Associated with Advanced Life Support Simulation Performance of Senior Medical Students

PURPOSE: Although use of simulation for medical students in medical education has increased, little is known about factors associated with performance on advanced life support simulation. The goal of this study was to determine which educational and psychosocial factors are associated with performance of senior medical students using a simulation resuscitation model. METHODS: Fourth year medical students enrolled in the study were divided into six groups. Subjects in each group underwent training in emergency medicine for a period of two weeks. This was a consecutive study conducted from March to July of 2009. Each student underwent an advanced cardiac life support (ACLS) simulation performance test while performance was graded by two ACLS instructors who were certified by the American Heart Association. The scores of the followings were collected: basic life support (BLS) practice, personality characteristics survey, case presentation, one post-training written test, and two planned tests for the Korean Medical Licensing Examination (KMLE). RESULTS: A total of 46 students participated in the study. As measured by the post-training written test and two planned tests for the KMLE, no association was observed between ACLS performance scores and personality type, BLS skills, or medical knowledge. However, scores on case presentations showed a moderate association with ACLS performance scores: r=0.390 (p<0.01). CONCLUSION: Results of this study demonstrated an association of ACLS simulation performance with case presentations. These results support the idea that the ability to manage resuscitation is associated with aptitude for analysis and coordination of patient management. These results provide guidance that can be applied to education of medical students.
