Purpose: Malnutrition affects all age groups, but older adults are particularly more vulnerable to nutritional deficiencies. This study evaluated the age-specific factors affecting malnutrition in hospitalized older adults. Methods: A retrospective study was conducted on inpatient elderly people who received artificial nutrition from 2010 to 2017. Data of demographics, diagnosis, type of nutrition therapy, number of comorbidity, fall risk assessment, Acute Physiologic Assessment and Chronic Health Evaluation (APACHE) score, and intensive care unit admission were collected. Malnutrition was defined as a body mass index (BMI) of less than 18.5 kg/m². Patients were classified as the young-old (65~74 years old), the old-old (75~84 years old), or the oldest-old (85 years old or older). Results: A total of 7,130 older adults were included, and 4,028 patients were classified as the young-old, 2,506 into the old-old, and 596 into the oldest-old. Proportion of malnutrition was higher in the oldest-old compared to the other groups. In multivariate analysis, parenteral nutrition, alcohol, and high risk of falls were factors affecting malnutrition in all groups. Parenteral nutrition and alcohol in the young-old, high risk of falls in the old-old, and male sex in the oldest-old were the factors affecting malnutrition by the age group. Conclusion: Older age was the most significant factor affecting malnutrition. Specific strategies by age are needed to improve nutritional status in hospitalized older adults as influencing factors for malnutrition vary among different age groups.

Purpose: The purpose of this descriptive study was to assess levels of stress, coping style, and nursing needs for hospitalized pregnant women diagnosed with preterm labor. Methods: Data were collected from 125 pregnant women aged between 20 and 40 years and diagnosed with preterm labor by OBGY units at 3 hospitals. Data were analyzed by frequency, percentage, t-test, and ANOVA with $Scheff{\acute{e}}$ test. Results: The level of stress among women was an average of 2.13 out of 4 points, the level of coping style was an average of 2.66, and nursing needs was an average of 2.83 out of 4 points. The level of stress was significantly different by job, length of hospital stay, type of hospital, and history of admission at obstetric unit. The level of coping style was significantly different by age and monthly income. The level of nursing needs was significantly different by type of hospital. Higher level of stress and coping style were related to higher level of nursing needs. There was no significant correlation between stress and coping style. Conclusion: The result showed the importance of nursing intervention dealing with stress, coping style and nursing needs for women with preterm labor. Nurses need to provide nursing interventions to reduce the stress, to strengthen the coping style, and to satisfy the nursing needs for pregnant women hospitalized due to preterm labor.

Objectives: This study was performed to evaluate the impact of glycosylated hemoglobin (HbA1c) level on characteristics and prognosis of maxillofacial fascial infection in diabetic patients. Materials and Methods: We reviewed the medical records of 72 patients (35 patients with HbA1c lower than 7.0% and 37 patients with HbA1c higher than 7.0%) diagnosed with maxillofacial fascial space infection and hospitalized for treatment at the Department of Oral and Maxillofacial Surgery in Dankook University Hospital (Cheonan, Korea) from January 2005 to February 2014. We compared demographics, parameters of glucoregulation (HbA1c), laboratory parameters of inflammation (white blood cell [WBC], C-reactive protein [CRP] count), type and number of involved spaces, type and number of antibiotics, period of hospitalization, number of surgical operations, need for tracheostomy, complications, computed tomography (CT), and microorganisms between the two groups. Results: Compared with the well-controlled diabetes mellitus (DM) group (HbA1c <7.0%), patients in the poorly-controlled (HbA1c ${\geq}7.0%$) DM group had the following characteristics: longer hospitalization periods, higher values of laboratory parameters of inflammation (WBC, CRP count) at the time of admission, higher number of antibiotics prescribed, more frequent complications, frequent deep neck space involvement, and distinctive main causative microorganisms. As the HbA1c level increases, hospitalization periods and incidence of complications increase gradually. Conclusion: This retrospective study suggests that regulation of DM significantly impacts maxillofacial fascial infection. Poorly controlled DM with high HbA1c level negatively influences the prognosis of infection.

Purpose: Intentional poisoning is a major public health issue in many parts of the world. This study was conducted to provide details regarding the epidemiology of intentional poisoning in a metropolitan emergency department and to identify the changing patterns and epidemiology of poisoning. Methods: A retrospective study was conducted to evaluate intentional poisoning of patients who visited the emergency department in a tertiary teaching hospital between 2001 and 2015. All intentional poisoning-related emergency department visits over three five year periods (2001-2005 (P1), 2006-2010 (P2) and 2011-2015 (P3)) were reviewed to investigate trends in intentional poisoning patients. Information regarding patient sex, age, time from episode to admission, psychiatric history, type of intoxicants, alcohol co-ingestion, gastric lavage, charcoal administration, any previous suicide attempts, need for hospitalization and death before discharge was reviewed. Results: A total of 1269 patients were enrolled in this study. The number of patients admitted during each period was P1=515, P2=439 and P3=315. Comparison of the three groups revealed significant differences according to age (p<0.001), psychiatric history (p<0.001), alcohol co-ingestion (p=0.013), gastric lavage (p<0.001), charcoal administration (p<0.001), need for hospitalization (p=0.044), repeated attempt (p<0.001) and type of intoxicants (p<0.001). Conclusion: The average age of intentional poisoning patients has increased. While the use of sedatives and multiple drugs increased, the use of pesticides and the antihistamine decreased.

Purpose: This study was done to compare breast feeding rates and factors influencing feeding practice between late preterm ($34{\leq}GA<37$) and preterm infants (GA<34). Methods: A survey was done of 207 late preterm and 117 preterm infants in neonatal intensive care units (NICU) of 4 university hospitals in D city. Data were collected from July 2009 to June 2010 from 324 medical records in the NICU. Breast-feeding at home was checked either by telephone survey or questioning during hospital visits. Results: Rate of breast feeding for late preterm infants was significantly lower than for preterm infants. There was no significant difference in breast-feeding at home. We found differences in factors influencing breast feeding between the two groups. Factors influencing feeding for late preterm infants were type of delivery, mothers' occupation, feeding type during hospitalization, time elapse from hospital discharge, total admission days, infant's body weight at first feeding and length of NPO (nothing by mouth). Factors influencing feeding for preterm infants were birth order, maternal disease and obstetric complications, and one-minute Apgar score. Conclusion: Results of the study show low rates of breast-feeding for late preterm infants indicating a need for breast-feeding education for mothers of these infants.

Adverse drug events (ADEs) are the most common type of adverse events in medical practice. Hospital admissions related to ADEs cost high and should be monitored to prevent them. While concerns about the ADEs are increasing, the frequency and characteristics of admissions related to ADEs have not been reported in Korea. The objective of the study was to assess the rate of hospital admission related to ADEs and their characteristics through ADE signal-based retrospective reviews of medical records. As results, a total of 1,420 patients had ADE signals suggesting potential ADEs from 3,494 patients who discharged from an academic medical center over one month period. Six pharmacists independently assessed the presence of ADEs after the review of patients' medical records. Among the 3,494 discharges, 62 admissions (1.8%) were found to be realted to ADEs. Of admissions with ADEs, 83.9% were moderate (category F by the NCC MERP classification), 37.2% were preventable, and 85.5% were type A reaction. The most frequent suspected drugs causing ADEs were antineoplastics (48.9%), and the most frequent ADE signal detecting hospital admissions related to ADEs was white blood cell count (24.2%). Hospital admissions related to ADEs were found through screening the ADE signals. The ADE signal-based retrospective review could be a practical approach for identifying hospital admissions related to ADEs.

The subjects of following research were 663 medical practitioners working at hospitals or bigger sized medical facilities in Pusan. Among the entire research subjects, it was shown that medical practitioners are notably and positively affected when their supervisors' type of leadership was either servant leadership or transformational leadership. The types of leaderships of supervisors that are recognized by medical practitioners were transformational leadership, transactional leadership, servant leadership. The effect of supervisors' leadership according to different type of role are as following. Under the circumstance of no personal and controlled variables, the each group of different medical occupants showed notable positive effects. Nurses corresponded to transformational leaderships, while admission and discharge corresponded to servant leadership. At the same time, medical technicians were most effected by both servant and transformational leadership.

Background: Personal mobility devices (PMDs) have become an increasingly popular transport modality globally. With increasing social interest in and demand for PMDs, the number of individuals visiting emergency departments with PMD-related injuries has also increased annually. This study aimed to evaluate injury patterns and treatment costs for patients treated in the department of plastic surgery in a trauma center. Methods: In this retrospective study, data concerning patients with PMD-related injuries from January 2017 to December 2021 were reviewed. The data retrieved included age, sex, alcohol consumption, helmet use, the type of impact, onset of injury, place of first visit, type of injury, admission status, operation status, and treatment cost. Multiple linear regression analysis was performed to determine the effects of various factors on cost. Results: Data were collected from 93 patients. Until 2019, the annual number of PMD-related accidents was less than 10; however, this number increased sharply in 2020. The average cost of hospitalization was USD 7,698 whereas the average cost of non-hospitalization was USD 631. Only fractures had a significant association with total cost in linear regression analysis (p< 0.001). Conclusion: The prevalence of PMD use and related injuries requiring plastic surgery during the study period showed significant health and financial costs both to the patients involved and to society. This cost could be reduced through stricter regulations concerning PMD use, advocating the use of protective gear, and promoting greater awareness of safety measures and of the consequences of PMD-related accidents.

Objectives: The purpose of this study was to analyze whether there are differences in medical expenses according to medical security type in the use of medical services with high disease burden such as coronary intervention. Methods: Chi-square test and covariance analysis(ANCOVA) were conducted to identify the differences in the characteristics and costs according to medical security type of 1,904 patients who underwent coronary intervention in a university hospital from 2011 to 2012. Hierarchical regression analysis was conducted to determine whether the cost affects medical expenses. Results: In the medical aid group, the proportion of women, those without a job, those without a spouse, and those who received hemodialysis was high, length of stay was high, patients using the emergency room and those who died was high. The medical aid patients were significantly higher in the non-benefit medical expenses, optional medical expenses, physician and admission, meals, medications and injections. National health insurance patients were significantly higher in procedure. The medical security type was found to be significant as a variable affecting the medical expenses. Conclusions: Provision of medical expenses should be managed in advance by providing prevention and education services for the vulnerable, and care services in the region should be provided to suppress the occurrence of medical expenses due to the increase in the number of days spent. In addition, it is necessary to support medical expenses to prevent unsatisfactory medical services from occurring for non-benefit and optional care.
