Development of an Instrument to Assess the Nursing Professional Pride

Purpose@#The purpose of this study was to develop an instrument to assess nursing professional pride. @*Methods@#Fifty-six preliminary items were identified through literature review and focus group interview of nurses working in a hospital. Of these, 45 preliminary instruments were completed over 0.80 of content validity index. To verify the reliability and validity of the preliminary instrument, data were collected from 294 nurses. The data were analyzed using factor analysis and multidimensional scaling analysis. @*Results@#From the factor analysis, 27 significant items were divided into 5 subscales. These subscales were as follows: feeling of vocation, role satisfaction, role of problem solver, self-achievement, and willingness to stay. The nursing professional pride also established criterion-related validity, discriminant validity, and group validity. Cronbach’s a of the instrument was .92, and the subscales ranged from .74 to .85. @*Conclusion@#The developed scale for nursing professional pride shows validity and reliability. The significance of this study is the development of an instrument capable of measuring nursing professional pride. To verify the relevance of this instrument, conducting comparative studies is suggested.

Validity of bispectral index monitoring during deep sedation in children with spastic cerebral palsy undergoing injection of botulinum toxin / 대한마취과학회지

BACKGROUND: This prospective study aimed to determine whether the bispectral index (BIS) is a valid objective tool for differentiating adequate from inadequate deep sedation in spontaneously breathing children with cerebral palsy (CP).METHODS: Propofol was titrated to increase the level of sedation with a continuous infusion of remifentanil at a rate of 0.05 μg/kg/min while maintaining spontaneous ventilation in 22 children with spastic CP, aged 3–18 years. The depth of sedation was assessed using the University of Michigan Sedation Scale (UMSS) and the Modified Observer’s Assessment of Alertness and Sedation (MOAAS) scale. Receiver operating characteristic curve analysis was performed to determine the cutoff BIS values for deep sedation, defined as a UMSS score of 3–4 and a MOAAS score of 0–1.RESULTS: The BIS values significantly changed with the increase in the level of sedation across both the UMSS and MOAAS scores (P < 0.001). The BIS values correlated with the UMSS (r = −0.795, P < 0.001) and MOAAS (r = 0.815, P < 0.001) scores. The cutoff BIS value to detect adequate deep sedation in children with CP was 61.5 (UMSS score: sensitivity 0.860, specificity 0.814; MOAAS score: sensitivity 0.794, specificity 0.811).CONCLUSIONS: The BIS value strongly correlates with the clinical sedation scales, such as the UMSS and MOAAS, during deep sedation in children with CP. Therefore, BIS monitoring can be used as a valid tool for assessing the level of propofol sedation in spontaneously breathing children with CP undergoing a botulinum toxin injection.

Adequacy of Nurse Staffing Level in Integrated Nursing Care / 간호행정학회지

PURPOSE: This study was done to evaluate the adequacy of nurse staffing in integrated nursing care. METHODS: Statistical data on integrated nursing care from the National Health Insurance Corporation was used in this study. We extracted hospital data and patient data related to patient needs for nursing care. We analyzed the differences in patient needs by staffing level of each type of medical institution. RESULTS: Approximately 70% of medical institutions provided nursing care by the mid level of nurse staffing, which was 1:6, 1:10 and 1:12 in the tertiary hospital, general hospital and semi-hospital, respectively. The patients' characteristics were significantly different by hospital type. Especially, the distribution of the main diagnosis was completely different between the tertiary hospital and semi-hospital. In the tertiary hospital, the patient needs measured by severity and activities of daily living dependency were higher at higher staffing level than at lower staffing level. However, the nurse staffing was less relevant to the patient needs in the general hospital and semi-hospital. CONCLUSION: To provide high-quality nursing care, accurate workload forecasting is required at the start, and then the standard nurse staffing level can established based on workload forecasting.

Sexual Maturation, Attitudes towards Sexual Maturity, and Body Esteem in Elementary-School Children

PURPOSE: The purpose of this study is to evaluate sexual maturation, attitudes toward sexual maturity, and body esteem in the sexual development of Korean elementary-school boys and girls. METHODS: A descriptive cross-sectional study was conducted with 399 fifth and sixth graders (192 boys and 207 girls). The data were analysed with a χ2 test, t-test, and Pearson correlation coefficients. RESULTS: Among the 207 girls, 70.5% had pubic hair growth, 68.1% had breast development, and 56.0% had a menstrual period. In boys, 59.4% of the 192 subjects experienced the development of external genitalia and 52.6% had pubic hair growth. Sexual maturation was related to grade (boys, t=7.07, p=.008; girls, t=12.76, p < .001), age (t=−2.20, p=.030; t=−4.11, p < .001), height (t=−5.16, p < .001; t=−7.52, p < .001), and weight (t=−2.89, p=.004; t=−5.19, p < .001) in both boys and girls. Girls were more likely to have sexual maturity than boys (χ2=22.29, p < .001). Boys showed more positive attitudes toward sexual maturity (t=2.10, p=.036) and higher body esteem (t=2.12, p=.035) than girls. CONCLUSION: This study shows that sexual maturation, attitude toward sexual maturity, and body esteem in sexual development differ between boys and girls. The findings indicate that it is necessary to develop a tailored sex-education program according to the sex of elementary-school children.

Policy Issues and New Direction for Comprehensive Nursing Service in the National Health Insurance / 간호행정학회지

PURPOSE: This study was done to identify issues surrounding comprehensive nursing care within the national health insurance, analyze results and problems within national health insurance and to suggest new policy directions for stability. METHODS: A literature search was performed using RISS, KISS, PUBMED databases. Eighteen studies were analyzed. RESULTS: For implementation of comprehensive nursing care, there was improvement in nursing and in facilities. By improvement of structure, this new system showed positive outcomes in term of patient satisfaction and indicators related to patient safety. However, issues related to overload, job stress and evaluation of the system remain. In order to establish this system, staffing levels for nurses and nurse aids need to be adjusted to appropriate levels that reflect requirements for nursing. In addition, range of work needs to be determined clearly. Lastly, regular and systematic evaluation is needed to provide safe quality services to patients and to prevent waste of financial resources. CONCLUSION: Comprehensive nursing care needs to be implemented in ways that patients can be provided with safe and high quality service. There is a need to resolve several issues to allow this new system to function.

Analysis of Qualitative Research Published in the Journal of Korean Academy of Nursing Administration (First publication to the end of 2016) / 간호행정학회지

PURPOSE: This study was done to analyze qualitative research published in the Journal of Korean Academy of Nursing Administration (JKANA). METHODS: Selected studies included 38 qualitative studies in which an interview was used and which were published in JKANA from 1995 to 2016 (22 years). Consolidated Criteria for Reporting Qualitative Research (COREQ), a reporting guideline for analysis of qualitative research was employed. RESULTS: Items that were included in less than half of the selected studies were as follows: interviewers' credentials, occupation, gender, and relationship established with participants in the 1st domain; non-participants, presence of non-participants, and transcripts returned in the 2nd domain; participant checking in the 3rd domain. CONCLUSION: Findings indicate that future challenges face JKANA qualitative researchers. First, the expansion of qualitative research should be ensured to explain complex interaction between humans and the environment. Second, a variety of qualitative research methods should be considered to enhance understanding of nursing fields. Third, research procedures should be described more precisely to increase transparency of research results. Fourth, not only personal information on the researcher but also how subjective opinions of the researcher reflected in the research process should be explained in detail to clarify the relationship between researchers and participants.

A Population-Based Genomic Study of Inherited Metabolic Diseases Detected Through Newborn Screening

BACKGROUND: A newborn screening (NBS) program has been utilized to detect asymptomatic newborns with inherited metabolic diseases (IMDs). There have been some bottlenecks such as false-positives and imprecision in the current NBS tests. To overcome these issues, we developed a multigene panel for IMD testing and investigated the utility of our integrated screening model in a routine NBS environment. We also evaluated the genetic epidemiologic characteristics of IMDs in a Korean population. METHODS: In total, 269 dried blood spots with positive results from current NBS tests were collected from 120,700 consecutive newborns. We screened 97 genes related to NBS in Korea and detected IMDs, using an integrated screening model based on biochemical tests and next-generation sequencing (NGS) called NewbornSeq. Haplotype analysis was conducted to detect founder effects. RESULTS: The overall positive rate of IMDs was 20%. We identified 10 additional newborns with preventable IMDs that would not have been detected prior to the implementation of our NGS-based platform NewbornSeq. The incidence of IMDs was approximately 1 in 2,235 births. Haplotype analysis demonstrated founder effects in p.Y138X in DUOXA2, p.R885Q in DUOX2, p.Y439C in PCCB, p.R285Pfs*2 in SLC25A13, and p.R224Q in GALT. CONCLUSIONS: Through a population-based study in the NBS environment, we highlight the screening and epidemiological implications of NGS. The integrated screening model will effectively contribute to public health by enabling faster and more accurate IMD detection through NBS. This study suggested founder mutations as an explanation for recurrent IMD-causing mutations in the Korean population.

Economic Effect of Home Health Care Services for Community-dwelling Vulnerable Populations

PURPOSE: In this study the costs and benefits of a home health care program were examined to evaluate the economic feasibility of the program. METHODS: The study participants included 349 patients in the community who had been registered at a home health care center for 5 years. The costs and benefits of the program were analyzed using performance data and health data. The benefits were classified as the effects of pressure ulcer care, skin wound care and catheters management. The program effect was evaluated on the change of progress using transition probability. Benefits were divided into direct benefit such as the savings in medical costs and transportation costs, and indirect benefits which included saving in productivity loss and lost future income. RESULTS: Participants had an average of 1.82 health problems. The input cost was KRW 36.8~153.3 million, the benefit was KRW 95.4~279.7 million. Direct benefits accounted for 53.4%~81.2%, and was higher than indirect benefits. The net benefit was greater than 0 from 2006 to 2009, and then dropped below 0 in 2010. CONCLUSION: The average net benefit during 5 years was over 0 and the benefit cost ratoi was over 1.00, indicating that the home health care program si economical.

Validity and Reliability of the Korean Version of the Expanded Nursing Stress Scale / 간호행정학회지

PURPOSE: This study was done to evaluate validity and reliability of the Korean version of the expanded nursing stress scale (ENSS). METHODS: Forward-backward translation of ENSS from English to Korean was conducted. The translated instrument was pilot-tested and administrated to 285 nurses who worked in five general hospitals in Korea. Internal consistency reliability was assessed using Cronbach's alpha and composite reliability. Validity was evaluated through construct validity with confirmatory factor analysis, convergent and discriminant validity. RESULTS: The Korean version of ENSS showed a reliable internal consistency with Cronbach's alpha .95 and composite reliability .99. Model fit indexes for 46 items were validated by confirmatory factor analysis(goodness of fit index .82, Tucker-Lewis index .92, root mean square error of approximation .04), indicating suitable construct validity. Factor loading of the 48 items (.47~.88) and average variance extracted out of nine factors (.52~.71.) indicated satisfactory convergent validity. Some values of square of the correlation coefficient between factors (.12~.89) were higher than average variance extracted values of each factor (.52~.71) so that it partly satisfied discriminant validity. CONCLUSION: Findings show that the Korean version ENSS has good reliability and suitable validity; therefore, can be used to assess and identify Korean nurses' job stress.

A Study on the Operating Status of Community-based Home Health Care Centers / 간호행정학회지

PURPOSE: This study was done to evaluate the operating status of community-based home health center for revitalization of the centers. METHOD: In this study performance data including organization plan and service utilization plan were evaluated according process theory. Target of evaluation was the community-based home health care center. RESULTS: The vulnerable part of the organization was the information system and financial resources. The home health center introduced PDA (Personal Digital Assistants) in 2005, however home health care nurses did not make full use of it. This service received full support from Seoul city and local government and there were no other sources of income. The vulnerable part of service utilization was service expansion and standardization due to vulnerability of organizational aspects. CONCLUSIONS: The home health care center provides high quality services to underprivileged people. In the future, these services should be provided with equity for continuous health care for this population.

The Effect of Self-help Tai Chi Over 16 Weeks in Community Program for Older Adults Korean American Women / 여성건강간호학회지

PURPOSE: The purpose of this study was to examine the effects of a 16-week Self-help Tai Chi for Arthritis (SHTC) combined with health education for Korean American older women. METHODS: This research was a designed quasi-experimental pre-posttest. Forty one women aged 55~79 were recruited 20 in SHTC group 21 in control group and, but twelve in SHTC group and thirteen in control group were left after 16 weeks. SHTC group was educated for 1 hour health education and 1hour TCA, once a week during 16 wks. Measurements for comparison were taken three times, at baseline, 8 wks and 16wks. The effect were evaluated with self-efficacy, shoulder flexibility, back flexibility, both hand grip strength and standing balance with closed eyes. RESULTS: All variables except for left hand grip strength at baseline had significant homogeneity between both groups. After 16 weeks intervention, there was a significant interaction effect of time and group on right hand grip strength by repeated measure of ANOVA (F=3.398, p=.044). No significant interaction effects were found on self-efficacy, shoulder and back flexibility, left hand grip strength and standing balance with closed eyes. CONCLUSION: I can suggest this self-help Tai Chi program may be effective partially, but further research is needed to establish the best times and periods to intervene for a better effect.

A Cost Benefit Analysis of Individual Home Visiting Health Care

PURPOSE: The purpose of this study is to evaluate the costs and benefits of individual home visiting health care using secondary data and literature review. METHODS: The total number of subjects was 1,008,837. A specific program was classified into disease management, care of infant, child and women, or elderly care. The costs and effects of a program were identified from a societal perspective, and the effects were converted into monetary terms or benefits. The total cost was calculated in the way that medical expenses, travel costs and productivity losses were offset by the decrease in benefits and thus only the program budget was included in the total cost. RESULTS: The total program cost was 47.6 billion won per year and the total annual benefit was estimated at 435.6 billion won. The benefits of arthritis management were the biggest among disease management programs. The net benefit was 388.0 billion won per year and the benefit/cost ratio was 9.16. CONCLUSION: Home visiting health care was validated to be economically effective. It made a positive contribution to improving the health status of vulnerable populations and reducing medical expenses. These results suggest that home visiting care should be extended more broadly to vulnerable populations.

Current Use of Dexamethasone Rescue Therapy for Bronchopulmonary Dysplasia

PURPOSE: The aim of this study is to investigate the current use of dexamethasone rescue therapy (DRT) for bronchopulmonary dysplasia (BPD). METHODS: This is a retrospective study of 251 BPD patients managed in the neonatal intensive care units at Seoul National University Childrens Hospital and Seoul National University Bundang Hospital between March 2004 and August 2008. The demographic data and clinical characteristics of the mothers and infants were analyzed. The infants were compared based on DRT responsiveness. The DRT complications were investigated. RESLUTS: Ninety-three patients (37.1%) were classified with severe BPD, DRT was only given to patients with severe BPD. Dexamethasone was administered to 24 patients (9.6%) whose respiratory status had precluded extubation, which indicated that conventional BPD management had failed. Fourteen patients (58.3%) who received DRT were responsive. DRT non-responders required more oxygenation and more complicated with pulmonary arterial hypertension (PAH). Responder had shorter length's of hospitalization and lower mortality rates. High dose dexamethasone was no more effective in weaning neonates from the ventilatior than low dose dexamethasone. Sepsis was the most common complication of DRT. CONCLUSION: DRT is a valuable treatment for severe BPD ahead of PAH development. DRT should not be performed in BPD patients with PAH due to the possibility of complications.

Pulmonary Aspergillus niger Fungus Ball Associated with Calcium Oxalate Crystal: A Case Report

Pulmonary aspergillomas are considered to represent saprophytic growth of hyphae within the preexisting lung cavity. Causative Aspergillus species are mostly composed of A. fumigatus and A. flavus and, occasionally, A. niger. It is difficult to identify these species using histopathologic evaluation without a culture of sputum and bronchoalveolar lavage. We recently experienced a case of pulmonary Aspergillus niger infection associated with characteristic calcium oxalate crystal formation. A large cavity contained hyphae with a typical conidial head, conidiophore, and conidia. Characteristic birefrigent calcium oxalate crystals were demonstrated in the cavity wall.

Expression of CD44v6 Protein in the Progression of Colorectal Carcinomas

During tumor progression, a subset of cells acquires metastatic properties, presumably through a series of genetic alterations. CD44 variant glycoproteins containing sequences encoded by exon v6 are related to tumor progression of human colorectal cancer. But their expression in normal colonic epithelium is controversial and studies of CD44 on each step of colorectal carcinogenesis are scanty. We studied CD44v6 expression in the normal colonic mucosa, adenoma, carcinoma in situ, and invasive colorectal carcinomas of different Astler-Coller stages. Endoscopically or surgically resected 36 normal colonic mucosa, 19 adenomas, 8 cases of carcinoma in situ, and 25 cases of carcinoma were selected. After immunohistochemical stain with CD44v6 antibody, positivity was graded as 0 to 4 based on the estimated percentage of positively stained tumor cells. The intensity of positive staining cells was also graded as 0 to 3. In all but one cases (97.2%), normal colorectal mucosa was negative for CD44v6. Positive rates in adenoma, carcinoma in situ, Astler-Coller stage A/B and C/D carcinoma were 73.6%, 88.9% and 87.5%, respectively. There was no statistically significant difference in the positivity between these groups. The staining intensity was significantly higher in the cases of stage C/D carcinoma group than those of adenomas (p<0.05). The percentage of positivity for CD44v6 was higher in stage C/D carcinoma group than adenoma, carcinoma in situ, and stage A/B carcinoma group (p<0.05). Expression of CD44v6 in the normal colonic mucosa was extremely rare and the positivity was increased according to the progression of colorectal tumors. Furthermore, it is more important to interpret the CD44v6 positivity according to the estimated percentage of positively stained tumor cells.
