Delta neutrophil index as a predictor of vesicoureteral reflux in children with febrile urinary tract infection

Purpose@#Delta neutrophil index (DNI) indicates immature granulocytes in peripheral blood and has been confirmed to be effective as a prognostic factor for neonatal sepsis. Also, it has been reported to have diagnostic value in acute pyelonephritis and in predicting vesicoureteral reflux (VUR) in the infant. We conducted the study to verify whether DNI is also helpful in the entire pediatric age group with febrile urinary tract infection (UTI). @*Methods@#Medical records of children hospitalized for febrile UTIs were analyzed retrospectively. All subjects underwent kidney ultrasound and voiding cystourethrography. In the group with and without VUR, we compared sex and age, and the following laboratory values: the white blood cell count, neutrophil, polymorphonuclear leucocyte, eosinophil, hemoglobin, platelet count, C-reactive protein, DNI value, and the finding of ultrasound. @*Results@#A total of 315 patients (163 males and 152 females; range, 0–127 months) were eligible, and 41 patients (13%) had VUR. As a result of univariate analysis, the white blood cell count, neutrophil, DNI, and ultrasonic abnormalities were high in the reflux group, and the hemoglobin and lymphocyte fraction values were low. The value of DNI and the abnormal ultrasound were significantly higher in the reflux group on the multivariate analysis. The area under the curve value of the receiver operating curve was higher in DNI (0.640; 95% confidence interval, 0.536–0.744; P=0.004), and the DNI cutoff value for VUR prediction was 1.85%. @*Conclusions@#We identified that ultrasound findings and DNI values were helpful predictors of VUR in pediatric febrile UTIs.

Correlation between Transient Elastography (Fibroscan ® ) and Ultrasonographic and Computed Tomographic Grading in Pediatric Nonalcoholic Steatohepatitis / 대한소아소화기영양학회지

Purpose@#This study aimed to examine the advantages and usefulness of transient elastography (Fibroscan ® ) in diagnosing non-alcoholic steatohepatitis in children and adolescents compared to those of abdominal computed tomography and liver ultrasonography. @*Methods@#Forty-six children and adolescent participants aged between 6 and 16 years who underwent transient elastography (Fibroscan ® ) as well as liver ultrasonography or abdominal computed tomography were included. Thirty-nine participants underwent liver ultrasonography and 11 underwent computed tomography. The physical measurements, blood test results, presence of metabolic syndrome, and the degree of liver steatosis and liver fibrosis were analyzed, and their correlations with transient elastography (Fibroscan ® ), abdominal computed tomography, and liver ultrasonography, as well as the correlations between examinations, were analyzed. @*Results@#Thirty-six participants (78.3%) were boys, and the mean age was 12.29±2.57 years, with a mean body mass index of 27.88±4.28. In the 46 participants, the mean values for aspartate aminotransferase, alanine aminotransferase, and total bilirubin were 89.87±118.69 IU/L, 138.54±141.79 IU/L, and 0.77±0.61 mg/dL, respectively. Although transient elastography (Fibroscan ® ) and abdominal computed tomography grading had a statistically significant positive correlation with aspartate aminotransferase and alanine aminotransferase values, the correlations between the results of grading performed by transient elastography (Fibroscan ® ), abdominal computed tomography, and liver ultrasonography were not statistically. @*Conclusion@#We confirmed that each examination was correlated with the results of some blood tests, suggesting the usefulness and possibility of diagnosis and treatment of steatohepatitis mediated by transient elastography (Fibroscan ® ) in the department of pediatrics.

Incidence of Extravasation in Acute Care Hospitals and Nurses’ Knowledge and Attitude toward Extravasation Prevention and Management / 임상간호연구

Purpose@#Extravasation of diagnostic and therapeutic materials might occur when the intravascular solution leaks into the surrounding tissues. Injury associated with extravasation depends on various factors. It may range from mild skin reaction to severe necrosis. However, the incidence rate for extravasation is largely unknown because of the limited reporting in Korea. Therefore, this study was conducted to identify the incidence of extravasation and nurses’ attitude and knowledge of extravasation for providing high-quality nursing care. @*Methods@#Three acute care hospitals were surveyed to estimate the occurrence of extravasation. Knowledge and attitude toward extravasation were investigated from 793 nurses working in six hospitals. @*Results@#The incidence rate of extravasation was 0.5%. Extravasation commonly occurred in elderly patients aged 66 or older (59.9%) and internal medicine (48.2%), and it happened 13.73±20.68 days after hospitalization on average.It mostly occurred in the forearm site (52.9%) and was mainly caused by parenteral nutrition (33.6%). The mean scores of nurses’ knowledge and attitude were 14.63±2.86 and 28.91±36.00, respectively. There was a significant negative correlation between the subjects' knowledge and attitude (r=-.11, p=.002). @*Conclusion@#It is necessary to have a reporting system that can accurately monitor the occurrence of extravasation for patient safety management. In addition, it is necessary to develop a protocol that can be applied to clinical practice and a nurse education program.

14q12q13.3 Deletion Diagnosed Using Chromosomal Microarray Analysis in an Infant Showing Seizures, Hypoplasia of the Corpus Callosum, and Developmental Delay

14q12q13.3 Deletion is a rare microdeletion syndrome associated with neurodevelopmental delay, failure to thrive, seizures, and abnormal brain development. Symptoms vary depending on the sites of gene deletion, and establishing the diagnosis is often difficult, as the condition cannot be detected with routine chromosome analysis. In this report, we present a patient with intrauterine growth retardation, microcephaly, muscle weakness, seizures, and hypoplasia of the corpus callosum who underwent diagnostic tests, including karyotyping in the neonatal period without leading to a specific diagnosis. The patient was confirmed with a serious developmental disorder, and a chromosomal microarray analysis was performed at 8 months of age, revealing a 14q12q13.3 deletion. In this case, the condition was diagnosed in early infancy, in contrast to previously reported cases, and the patient had diverse and severe symptoms. Establishing the diagnosis of 14q12q13.3 deletion syndrome allows better management of patient care and genetic counseling for the parents.

Clinical Usefulness of ¹⁸F-FC119S Positron-Emission Tomography as an Auxiliary Diagnostic Method for Dementia: An Open-Label, Single-Dose, Evaluator-Blind Clinical Trial

Mortality Rate and Major Causes of Death by Gestational Age in Korean Children under 5 Years of Age

Background@#Preterm birth is associated with increased infant mortality. However, it is not clear whether prematurity is associated with mortality after 1 year of age. There is a lack of research on mortality rate and causes of death after infancy in preterm babies in Korea. We aimed to analyze the mortality rates and causes of deaths up to 5 years of age in Korea. @*Methods@#Using the Microdata Integrated Service of Statistics Korea database, this retrospective cohort study screened infants born between 2010 and 2012. After applying the exclusion criteria, 1,422,913 live births were classified into the following groups by gestational age: those born at < 32 weeks' gestation (n = 10,411), those born between 32 and 36 weeks' gestation (n = 75,657), and those born at ≥ 37 weeks' gestation (n = 1,336,845). The association of gestational age with mortality in infancy (< 1 year of age) and childhood (1–5 years of age) was analyzed, with and without covariates. The major causes of death in infancy and childhood were analyzed by gestational age. @*Results@#Overall, 4,930 (0.3%) children died between birth and 5 years of age, with 19.1% of these deaths occurring after infancy. Adjusted hazard ratios (HRs) for infant death were 78.79 (95% confidence interval [CI], 71.33–87.04) and 4.62 (95% CI, 4.07–5.24) for the < 32 and 32–36 weeks groups, respectively, compared to the full-term group; the adjusted HRs for deaths occurring at ages 1–5 years were 9.25 (95% CI, 6.85–12.50) and 2.42 (95% CI, 1.95–3.01), respectively. In infancy, conditions originating in the perinatal period were the most common cause of deaths in the < 32 and 32–36 weeks groups (88.7% and 41.9%, respectively). Contrarily, in the ≥ 37 weeks group, conditions originating in the perinatal period explained 22.7% of infant deaths, with congenital malformations primarily accounting for 29.6% of these deaths. The most common cause of death in children (after infancy) in the < 32 weeks group was perinatal causes (25.0%); in the 32–36 weeks group, congenital malformation and nervous system disease were the common causes (21.7% and 19.1%, respectively). In the ≥ 37 weeks group, injury, poisoning, and other consequences of external causes explained 26.6% of childhood deaths, followed by neoplasms and nervous system disease (15.7% and 14.7%, respectively). @*Conclusion@#Low gestational age is associated with not only infant mortality but also child mortality. The major causes of death differed by gestational age in infancy and childhood.For the care of preterm infants, especially those born at < 32 weeks' gestation, particular attention and continuous monitoring are needed in consideration of the major causes of deaths until 5 years of age.

Juvenile Polyp associated with Hypovolemic Shock Due to Massive Lower Gastrointestinal Bleeding / 대한소아소화기영양학회지

Juvenile polyps are the most common types of polyps in children, and patients usually present with lower gastrointestinal (GI) bleeding as the predominant symptom. These lesions, which are referred to as hamartomas, usually measure approximately 2 cm in size and are benign tumors located mainly in the rectum and sigmoid colon. The most common symptom of a juvenile polyp is mild intermittent rectal bleeding. It is rare for anemic patients because the amount of blood loss is small and often not diagnosed immediately. We present the case of a 6-year-old girl with a juvenile polyp in the distal transverse colon, who developed hypovolemic shock due to massive lower GI bleeding. Pediatricians must perform colonoscopy for thorough evaluation of polyps, because their location and size can vary and they can cause massive bleeding.

Usefulness of Transient Elastography for Non-Invasive Diagnosis of Liver Fibrosis in Pediatric Non-Alcoholic Steatohepatitis

BACKGROUND: Transient elastography (FibroScan®) is a non-invasive and rapid method for assessing liver fibrosis. While the feasibility and usefulness of FibroScan® have been proven in adults, few studies have focused on pediatric populations. We aimed to determine the feasibility and usefulness of FibroScan® in Korean children. METHODS: FibroScan® examinations were performed in 106 children (age, 5–15 years) who visited the Konyang University Hospital between June and September 2018. Liver steatosis was measured in terms of the controlled attenuation parameter (CAP), while hepatic fibrosis was evaluated in terms of the liver stiffness measurement (LSM). Children were stratified into obese and non-obese controls, according to body mass index (≥ or 95% percentile) (P 5.5 kPa), whereas the remaining 29 did not (LSM < 5.5 kPa). Obese children with fibrosis had higher levels of AST (73.57 ± 56.00 vs. 39.86 ± 31.93 IU/L; P = 0.009), ALT (132.47 ± 113.88 vs. 48.66 ± 51.29 IU/L; P = 0.001), and gamma-glutamyl transferase (106.67 ± 69.31 vs. 28.80 ± 24.26 IU/L; P = 0.042) compared to obese children without fibrosis. LSM had high and significant correlation (P < 0.05) with AST, ALT, homeostasis model assessment for insulin resistance, and AST-to-platelet ratio index. CONCLUSION: FibroScan® is clinically feasible and facilitates non-invasive, rapid, reproducible, and reliable detection of hepatic steatosis and liver fibrosis in the Korean pediatric population.

Clinical manifestation of Campylobacter enteritis in children / 소아과

PURPOSE: Timely antibiotic therapy in selected cases of diarrhea associated with bacterial infections can reduce the duration and severity of illness and prevent complications. The availability of a predictive index before identification of causative bacteria would aid in the choice of a therapeutic agent. METHODS: The study included patients admitted to the pediatrics unit at Konyang University Hospital for acute inflammatory diarrhea from August 1, 2015 to July 31, 2016 who underwent multiplex polymerase chain reaction testing. Of 248 patients, 83 had positive results. The clinical symptoms and blood test results were examined in 61 patients with Campylobacter spp. (25 patients), Salmonella spp. (18 patients), and Clostridium perfringens (18 patients) infections. The mean age of the 61 patients (male:femal=31:30) was 84.0±54.8 months, and the mean hospital stay was 4.6±1.7 days. RESULTS: There were no statistical differences in sex, age, clinical symptoms, or signs. Patients with Campylobacter infection were significantly older (P=0.00). C-reactive protein (CRP) levels in patients with Campylobacter infection were higher than those in the other 2 groups, at 9.6±6.1 mg/dL. The results of receiver-operating characteristic curve analysis showed that the cutoff age was ≥103.5 months (sensitivity, 72%; specificity, 86%) and the CRP cutoff level was ≥4.55 mg/dL (sensitivity, 80%; specificity, 69%). CONCLUSION: Age (≥103.5 months) and higher CRP level (≥4.55 mg/dL) were good predictors of Campylobacter enterocolitis. If neither criterion was met, Campylobacter enterocolitis was unlikely (negative predictive value 97.2%). When both criteria were met, Campylobacter enterocolitis was highly likely.

The improvement of right ventricular function after adenotonsillectomy in children with obstructive sleep apnea / 소아과

PURPOSE: Adenotonsillar hypertrophy (ATH) that causes upper airway obstruction might lead to chronic hypoxemic pulmonary vasoconstriction and right ventricular (RV) dysfunction. We aimed to evaluate whether adenotonsillectomy (T&A) in children suffering from obstructive sleep apnea (OSA) due to severe ATH could improve RV function. METHODS: Thirty-seven children (boy:girl=21:16; mean age, 9.52±2.20 years), who underwent T&A forsleep apnea due to ATH, were included. We analyzedthe mean pulmonary artery pressure (mPAP), the presence and the maximal velocity of tricuspid regurgitation (TR), the tricuspid annular plane systolic excursion (TAPSE), and the right ventricular myocardial performance index (RVMPI) with tissue Doppler echocardiography (TDE) by transthoracic echocardiography pre- and post-T&A. The follow-up period was 1.78±0.27 years. RESULTS: Only the RVMPI using TDE improved after T&A (42.18±2.03 vs. 40±1.86, P=0.001). The absolute value of TAPSE increased (21.45±0.90 mm vs. 22.30±1.10 mm, P=0.001) but there was no change in the z score of TAPSE pre- and post-T&A (1.19±0.34 vs. 1.24±0.30, P=0.194). The mPAP was within normal range in children with ATH, and there was no significant difference between pre- and post-T&A (19.6±3.40 vs. 18.7±2.68, P=0.052). There was no difference in the presence and the maximal velocity of TR (P=0.058). CONCLUSION: RVMPI using TDE could be an early parameter of RV function in children with OSA due to ATH.

Comparison of Birth Outcomes Based on Maternal Ethnicity in Korea: Korean, Vietnamese, and Chinese, 2010–2015

PURPOSE: The purpose of this study is to compare birth outcomes based on maternal ethnicity in Korea. METHODS: Using the birth data of Statistics Korea from 2010 to 2015, this study selected data from infants with a Vietnamese mother and Korean father (Vietnamese/Korean group), and a Chinese mother and Korean father (Chinese/Korean group), to compare them with that of a Korean mother and Korean father (Korean/Korean group). The newborn infants' birth outcomes and parental characteristics were investigated, and trends in annual changes were compared. In addition, this study investigated whether the mother's ethnicity affected the mean birth weight. RESULTS: Gestational age and birth weight were highest in the Chinese/Korean group, and were slightly lower in the Korean/Korean and Vietnamese/Korean group, in that order. The highest rate of preterm birth before 37 weeks and low birth weight rate were observed in the Vietnamese/Korean group; 4.62% and 4.26%, respectively. From 2010 to 2015, the mean gestational age decreased in all the three groups, and the preterm birth rate increased at gestational ages less than 37 weeks. However, the birth weight decreased only in the Korean/Korean group, but increased in the Chinese/Korean and Vietnamese/Korean groups. In addition, we found that factors such as parents' educational levels, percentage of hospital births, and appropriate maternal age improved in the Vietnamese/Korean group. CONCLUSION: This study confirms that the mean birth weight and low birth weight rate are affected by maternal ethnicity in Korea. Therefore, careful research and active national support policies are needed.

Gastrointestinal Mucormycosis in Extremely Low Birth Weight Infants Mimicking Atypical Necrotizing Enterocolitis and Intussusception

Neonatal gastrointestinal mucormycosis, a rare disease with a high mortality rate, shows a rapid progressive course in premature infants with an immature immune system. We report the case of a male neonate weighing 970 g, delivered via cesarean section at 27 weeks, as one of a pair of dizygotic twins. From the 7(th) day after birth, bile was seen to drain through the orogastric tube, and paralytic ileus was noted on performing an abdominal X-ray. Thus, oral feeding was discontinued because necrotizing enterocolitis (NEC) was highly suspected. On the 9(th) day after birth, a firm mass was palpable in left upper abdominal quadrant, but no pneumatosis intestinalis was observed on performing abdominal X-ray. Small bowel intussusception was suspected on performing abdominal ultrasonography. Based on these findings, an exploratory laparotomy was performed, and although no intussusception was found intraoperatively, we performed a partial gastrectomy and hemicolectomy due to the presence of necrotic changes and perforations of the stomach and colon. Postoperatively, he was observed to have hypotension with persistence of hemorrhage at the surgical site. He died on the 11(th) day after birth. Intraoperative histopathological examination of stomach and colon showed fungal aseptate hyphae with broad branching. Gastrointestinal mucormycosis was confirmed based on findings of vascular involvement in the form of fungal hyphae and thrombosis in the transmural blood vessels. We report a case of an extremely low birth weight infant with neonatal gastrointestinal mucormycosis with an initial clinical presentation suggestive of intussusception and atypical NEC.

Structural Equation Modeling on Health-Related Quality of Life in Adults with Epilepsy

PURPOSE: This study aimed to identify variables influencing the health-related quality of life (HRQoL) of adults with epilepsy in order to establish a structural model and design an intervention strategy to improve patients' HRQoL. METHODS: The selected subjects were 212 patients with epilepsy aged between 18 and 70 years who were currently receiving treatment from hospital, general hospital, and clinic. They were surveyed using a structured questionnaire. RESULTS: The goodness of fit measures of the final hypothetical model were as follows: χ2/df=2.51, GFI=.91, AGFI=.90, CFI=.96, SRMR=.04, NFI=.93, and RMSEA=.08. The major variables influencing the HRQoL of adults with epilepsy were epilepsy self-efficacy, depression, social support, and side effects of anti-epileptic drugs (AEDs), which were significant in the mentioned order, whereas the duration of AEDs use and perceived stigma did not show any effects. Six variables accounted for 75.6% of HRQoL. Variables having a direct and total effect on the HRQoL of adults with epilepsy were the side effects of AEDs, social support, epilepsy self-efficacy, and depression, and those with an indirect effect were the side effects of AEDs and social support. CONCLUSION: It is necessary to accurately identify the side effects of AEDs in adults with epilepsy and accurately observe the physical changes caused by depression. In addition, it is imperative to establish an active and effective nursing intervention program to strengthen the self-efficacy of the patients and to improve their quality of life through social support provided by family members and medical professionals.

Age-adjusted plasma N-terminal pro-brain natriuretic peptide level in Kawasaki disease / 소아과

PURPOSE: Recent reports showed that plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) could be a useful biomarker of intravenous immunoglobulin (IVIG) unresponsiveness and coronary artery lesion (CAL) development in Kawasaki disease (KD). The levels of these peptides are critically influenced by age; hence, the normal range and upper limits for infants and children are different. We performed an age-adjusted analysis of plasma NT-proBNP level to validate its clinical use in the diagnosis of KD. METHODS: The data of 131 patients with KD were retrospectively analyzed. The patients were divided into 2 groups—group I (high NT-proBNP group) and group II (normal NT-proBNP group)—comprising patients with NT-proBNP concentrations higher and lower than the 95th percentile of the reference value, respectively. We compared the laboratory data, responsiveness to IVIG, and the risk of CAL in both groups. RESULTS: Group I showed significantly higher white blood cell count, absolute neutrophil count, C-reactive protein level, aspartate aminotransferase level, and troponin-I level than group II (P<0.05). The risk of CAL was also significantly higher in group I (odds ratio, 5.78; P=0.012). IVIG unresponsiveness in group I was three times that in group II (odds ratio, 3.35; P=0.005). CONCLUSION: Age-adjusted analysis of plasma NT-proBNP level could be helpful in predicting IVIG unresponsiveness and risk of CAL development in patients with KD.

Granular cell tumor of the esophagus in an adolescent / 소아과

Esophageal granular cell tumor (GCT) is a rare neoplasm originating from the Schwann cells of the submucosal neuronal plexus. Histology is the gold standard for its diagnosis. Endoscopic resection or surgical excision should be considered, depending on the potential for malignancy. Here, we report a case of an esophageal GCT in an adolescent. A 12-year-old boy presented with a 1-year history of dysphagia and vomiting. Upper gastrointestinal endoscopic examination and esophagography showed narrowing of the midesophagus, and computed tomography angiography of the thoracic aorta revealed an esophageal or periesophageal mass posterior to the paratracheal segment of the esophagus. The tumor was surgically excised, and based on the pathological findings, esophageal GCT was diagnosed.

Influence of Job Stress and Professional Self-concept on Job Satisfaction among Nurses in Rehabilitation Units / 재활간호학회지

PURPOSE: The purpose of this study was to define the relationships between job stress, professional self-concept, and job satisfaction among nurses in rehabilitation units and to identify factors that influence job satisfaction. METHODS: This study surveyed 240 nurses working at the rehabilitation units of 10 hospitals located in G City. To collect the data, nurses' job stress, the professional self-concept of nurses instrument (PSCNI), and the Korean-Minnesota Satisfaction Questionnaire (K-MSQ) were used. The data were analyzed through t-tests, ANOVA, Pearson's correlation coefficient, and multiple regression using the SPSS/WIN 18.0 program. RESULTS: The scores for job stress, professional self-concept, and job satisfaction were 3.34+/-0.61, 72.36+/-8.64 and 3.17+/-0.39, respectively. Job satisfaction and job stress showed a low-level negative correlation with statistical significance (r=-.13, p=.042), whereas a medium-level positive correlation was found between job satisfaction and professional self-concept (r=.46, p<.001). Job stress, professional self-concept, total career length and size of working hospital explained approximately 25.8% of job satisfaction (F=17.52, p<.001). CONCLUSION: Considering the results in this study, it is necessary to develop a practical educational program to establish positive professional self-concept for nurses in rehabilitation units. Such efforts must be supported by clinical nursing administrations through policies aimed at reducing job stress and increasing job satisfaction.

Fecal calprotectin concentration in neonatal necrotizing enterocolitis / 소아과

PURPOSE: Among the many factors associated with acute intestinal mucosal infection, numerous studies have proposed the usefulness of fecal calprotectin. The aim of this study was to evaluate the usefulness of fecal calprotectin in the diagnosis of necrotizing enterocolitis (NEC). METHODS: We collected 154 stool samples from 16 very low birth weight and premature newborns at the Konyang University Hospital neonatal intensive care unit or neonatal nursery. The stool samples were collected using the Calprest device, and the fecal calprotectin level was measured with the BUHLMANN Calprotectin enzyme-linked immunosorbent assay kit. RESULTS: Fecal calprotectin levels were significantly higher in the NEC group than in the non-NEC group (P=0.02). There was a significant positive linear relationship between the fecal calprotectin level and number of days after birth (P=0.00) in the gestational age or =26 weeks and <30 weeks group. There was no difference in the calprotectin levels according to the type and method of feeding between the NEC and non-NEC groups. CONCLUSION: Fecal calprotectin levels were significantly increased in premature infants with NEC. The fecal calprotectin test is a noninvasive, easy, and useful tool for the diagnosis of NEC.

Increase in Aminotransferase Levels during Urinary Tract Infections in Children / 대한소아소화기영양학회지

PURPOSE: The aim of this study was to evaluate the prevalence of increased aminotransferase levels and to identify associated factors in children admitted to hospital with urinary tract infections (UTIs). METHODS: The study included children with a diagnosis of UTI who were admitted to the Konyang University Hospital from January 2007 to May 2011. The total number of patients was 249 and the mean age was 15.88+/-28.21 months. UTI was defined as a positive urine culture (>105/colony forming unit [CFU]) with pyrexia. Patients were treated by intravenous antibiotics, such as ampicillin/sulbactam, aminoglycoside, cephalosporins or vancomycin. Patients with neonatal jaundice or other liver disease were excluded. We investigated the relationship of aminotransferase levels with the type of antibiotic, degree of vesicoureteral reflux (VUR), and causative organisms. RESULTS: Children with increased aminotransferase levels were younger than those with normal levels (p=0.001), but white blood cell count, platelet count, causative organisms, type of antibiotics and presence of VUR were not associated with aminotransferase levels. Aminotransferase levels became normal within 1 month after discharge without special measures, except in 1 case. CONCLUSION: We found that many children with UTI have abnormal aminotransferase levels. In most cases, this change is mild and self-limiting. We conclude that increased aminotransferase level increase during UTI do not require unnecessary tests and excessive treatment.

Factors Affecting Burnout among Clinical Nurses according to Positive Psychological Capital / 간호행정학회지

PURPOSE: The purpose of this study was to analyze factors affecting burnout among clinical nurses according to Positive Psychological Capital. METHODS: The study design was a descriptive survey and questionnaires were collected from 412 clinical nurses who worked in a general hospital in "J" city. Data were analyzed using frequency, percentage, mean, standard deviation, independent t-test, One-way ANOVA, Scheffe test, Pearson Correlation, and hierarchical multiple regression. RESULTS: In Model individual characteristics accounted for 27.8% of the influence on burnout. In model II with the addition of the 4 factors; Self-efficacy, Hope, Resilience, Optimism, individual characteristics accounted for 48.5% of the influence on burnout. Optimism and Resilience of the Positive Psychological Capital sub-variables were statistically useful as factors influencing burnout. CONCLUSION: The results indicate that it is necessary to develop active human resource management and educational programs to decrease burnout and strengthen the Positive Psychological Capital of the nurses.
