Objectives: This study aims to determine the risk factors predicting rehospitalization by comparing three models and selecting the most successful model. Methods: In order to predict the risk of rehospitalization within 28 days after discharge, 11 951 inpatients were recruited into this study between January and December 2009. Predictive models were constructed with three methods, logistic regression analysis, a decision tree, and a neural network, and the models were compared and evaluated in light of their misclassification rate, root asymptotic standard error, lift chart, and receiver operating characteristic curve. Results: The decision tree was selected as the final model. The risk of rehospitalization was higher when the length of stay (LOS) was less than 2 days, route of admission was through the out-patient department (OPD), medical department was in internal medicine, 10th revision of the International Classification of Diseases code was neoplasm, LOS was relatively shorter, and the frequency of OPD visit was greater. Conclusions: When a patient is to be discharged within 2 days, the appropriateness of discharge should be considered, with special concern of undiscovered complications and co-morbidities. In particular, if the patient is admitted through the OPD, any suspected disease should be appropriately examined and prompt outcomes of tests should be secured. Moreover, for patients of internal medicine practitioners, co-morbidity and complications caused by chronic illness should be given greater attention.

The purpose of this study was to explore the structure of nursing needs during labor pain as perceived by women who have given birth. The phenomenological perspective of qualitative research theory guided the approach to the study. The sample consisted of 20 women who had undergone normal labor and had delivered a healthy baby at term. Collection of data was by means of in-depth interviews conducted 1-2 days after delivery in the admission room from March to may 1998. On average, the interviews lasted for about 30 minutes. Interviews were taken with the consent of the subjects. Data were analyzed by means of Giorgi's method and categorized according to the similarities of their contents. The investigator read the data repeatedly to identify themes and categories. Four categories were : 1) a sense of security 2) self esteem 3) willingness to learn 4) a sense of comfort. Under these categories there were twelve themes. I. A sense of security : (a) presence (b) conversation (c) touching II. Self esteem : (a) praise (b) encouragement (c) treating the women with respect (d) caregiver with good character III. Willingness to learn : (a) teaching (b) information IV. A sense of comfort : (a) self controlled pain relief (b) artificially controlled pain relief (c) skillfulness of caregiver The findings should sensitize nurses to the various needs of women in labor who are under their care. Further research should focus on developing instruments to assess the nursing needs of parturients. Researchers also need to identify ways to assess women's satisfaction with nursing needs.

Purpose: The purpose of this study was to investigate the effects of education and practice of the maternal role and becoming a mother using the concepts of self-confidence in caring, maternal attachment, and maternal identity. Methods: A non-equivalent control group non-synchronized design was used. Data was collected with the use of self-administered questionnaires from November 2007 to April, 2008. A total of 54 women at a Sanhujoriwon (postpartum care center) participated in the study. The experimental group consisted of 26 women (Nov-Dec), whereas the control group had 28 women (Feb-Apr). Education and practice on the maternal role was given individually and consisted of explanations, demonstrations and practice on breast feeding (day1 to 3), maternal attachment (day 8 to 9), bathing (day 10 to 11) and infant healthcare (day 13 to 14). The experimental group received education and practice on the maternal role while the control group received routine education only. Results: Data collection was done using pre and post questionnaires at admission and fourteen days later. The experimental group showed significant increases in self-confidence in caring (t=-3.31, p=.002) and maternal identity (t=-2.16, p=.036) compared to the control group. Conclusion: Education and practice on the maternal role and being a mother was an effective intervention in increasing self-confidence in caring and maternal identity.

Purpose: This study examined the effects of a breastfeeding coaching program for mothers on growth and neonatal jaundice in late preterm infants (LPIs). Methods: This was a quasi-experimental study (non-randomized intervention) with a time-series design. The study was conducted among 40 LPIs who were admitted to the neonatal intensive care unit of a university hospital in Daegu, South Korea. In the order of admission, the first 21 infants were assigned to the experimental group, and 19 were assigned to the control group. The intervention program consisted of home- based and web-based practical breastfeeding support education for mothers across a total of 5 sessions. Infant growth was measured using body weight, length, and head circumference, and neonatal jaundice was assessed using transcutaneous bilirubin levels. Results: The likelihood of breastfeeding for infants in the experimental group at 4 weeks after discharge was the same as on the day of discharge, whereas it steadily decreased in the control group. There were significant differences in head circumference between the groups. However, weight, length, and transcutaneous bilirubin levels did not show a significant group-time interaction. Conclusion: A formal breastfeeding coaching program should be considered in clinical settings and at home within the first few weeks postpartum.

Purpose: The number of glyphosate and glufosinate intoxication cases are increasing in Korea. This study was undertaken is to compare the clinical manifestations of poisoning by these two herbicides and to document severities and clinical outcomes. Methods: We retrospectively evaluated cases of glyphosate or glufosinate intoxication among patients that visited our emergency department between January 1, 2013, and December 31, 2017. Incidences of intoxications were analyzed over this five year period, and underlying diseases, transportation, mental state, shock occurrence, inotropics, gastric lavage, charcoal administration, intubation and ventilator therapy, and hemodialysis were investigated. In addition, we included transfer to the intensive care unit, incidences of pneumonia and of other complications, death, and hopeless discharge. Results: There were 119 cases of glyphosate intoxication and 42 of glufosinate intoxication. Levels of consciousness were lower for glufosinate and vasopressor usage was higher due to a high shock rate (p=0.019). In addition, many patients were referred to the ICU for intubation and ventilation. The incidences of pneumonia and of other complications were significantly higher for glufosinate. Conclusion: Overall glufosinate intoxication was found to be more severe than glyphosate intoxication as determined by complication and ICU admission rates.

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 recent increase in electric scooter (e-scooter) use has been accompanied by an increase in injuries from e-scooter-related accidents. Studies have reported that most such injuries are minor, and physicians may therefore underestimate the severity of such injuries. This study investigated the types and severity of injuries caused by isolated e-scooter accidents (i.e., those that did not involve colliding with other cars or falling from heights). Methods: This prospective observational study was conducted from May to December 2021 at Dankook University Hospital tertiary medical center. The demographic data of patients injured in isolated e-scooter-related accidents were collected. All injuries were categorized by body part. Results: Fifty eligible patients visited our emergency department during the study period. Of these, 76% were categorized as nonemergency, and 62% were discharged after initial evaluation and treatment at the emergency department. Another 10% were admitted to the intensive care unit (ICU) and 18% to the ward, with nine patients receiving at least one operation. The average hospital stays were 2.4 days in the ICU and 9 days in the ward. One death occurred due to traumatic brain injury (overall mortality rate, 2%). Multiple fractures of the left third through ninth ribs combined with lung laceration and fractures of T12 and L4 were noted. Conclusions: Various types and severities of injuries can occur in isolated e-scooter accidents. While most such injuries are minor, some will require ICU admission or surgery, and deaths can occur. Physicians should not underestimate the severity of such injuries.

Objectives: This study compared the number of graduates in each region for the past 6 years and the number of dental hygienists working in dental clinics by region to evaluate the trend of dental hygienists moving to work areas after graduation. Methods: Health care big data open system_medical manpower statistics, resident population and household status data by year, and education statistics service were used to calculate the number of dentists and dental hygienists, admission status by region, number of dental hygienists per 100,000 population, number of dental hygienists per number of dentists, and distribution of dental hygienists by region. Results: Although the number of active dental hygienists increased in the metropolitan area, the ratio of dental hygienists to dentists did not improve significantly. In addition, the number of students enrolled in provincial universities decreased, and there were fewer active dental hygienists than graduates in provincial areas. Conclusions: Although the number of active dental hygienists increased due to increase in the number of dental hygiene departments, it was found that rural areas did not have a significant impact on the availability of dental hygienists as the graduates moved to the metropolitan area.

Purpose: The purpose of this study was to develop a motivational enhancement therapy (MET) for coronary artery disease (CAD) patients in early stages of health behavior change and evaluate its effects on health motivation, the stages of change, health behaviors, and cardiovascular risk factors. Methods: Using a non-equivalent control pre-post design, the study was conducted on 42 CAD patients who underwent medical treatment or percutaneous coronary interventions in a hospital. The intervention group (n=21) received the MET (MET 1 during admission, MET 2 after discharge via telephone). The control group (n=21) received a standard care. Data were analyzed using descriptive statistics, ${\chi}^2-test$ and t-test with the SPSS 12.0 program. Results: Participants in the intervention group reported significantly increased scores of health motivation (t=-2.093, p=.043), the stages of change (t=-5.682, p<.001), and health behaviors (t=-3.069, p=.004) and significantly decreased scores of cardiovascular risk factors (t=2.131, p=.039) compared to those of the control group. Conclusion: The findings indicate that the MET is an effective intervention in improving health behaviors and decreasing cardiovascular risk factors for CAD patients.

Objective : This study aimed to evaluate the clinical feasibility of the combination of ultrasound and nerve stimulator guidance in transforaminal epidural steroid injections (TESIs) to manage lumbosacral chronic radicular pain. Methods : Using the combination of nerve stimulator and ultrasound guidance, TESIs were performed in 125 segments of 78 patients who presented with chronic lumbar radicular pain. Demographic characteristics and surgical outcomes were recorded on admission, pre-procedural and post-procedural for 1-week, 1-month, 3-month, and 6-month follow-ups. The result was measured using the Numeric rating scale (NRS) and Oswestry disability index (ODI). Results : Patients who received TESIs showed significant improvements on two evaluation tools (NRS, ODI), compared to that before procedure (p<0.001). No significant complications were observed for 6 months' follow-up. Conclusion : The result suggests that a combination of ultrasound and nerve stimulator guidance in transforaminal epidural injections is safe, reliable and effective for short-term management of lumbar disc herniation. It is a promising technique and has shown good results in providing intermediate pain relief.
