Identifying Main Themes in Diabetes Management Interviews Using Natural Language Processing-Based Text Mining.

This study aimed to identify the main themes from exit interviews of adult patients with type 2 diabetes after completion of a diabetes education program. Eighteen participants with type 2 diabetes completed an exit interview regarding their program experience and satisfaction. Semistructured interview questions were used, and the interviews were auto-recorded. The interview transcripts were preprocessed and analyzed using four natural language processing-based text-mining techniques. The top 30 words from the term frequency and term frequency-inverse document frequency each were derived. In the N-gram analysis, the connection strength of "diabetes" and "education" was the highest, and the simultaneous connectivity of word chains ranged from a maximum of seven words to a minimum of two words. Based on the CONvergence of iteration CORrelation (CONCOR) analysis, three clusters were generated, and each cluster was named as follows: participation in a diabetes education program to control blood glucose, exercise, and use of digital devices. This study using text mining proposes a new and useful approach to visualize data to develop patient-centered diabetes education.

Exploring the Knowledge Structures of Korean and International Nursing Research on Premature Infants Using Text Network Analysis.

This study aimed to identify the knowledge structures of Korean and international nursing studies on premature infants using text network analysis, which represents a text as a network graph that describes how keywords are linked. This network graph refers to a knowledge structure. International and Korean journal databases were searched to extract nursing studies regarding premature infants published in academic journals from 1998 to 2020. Abstracts from the selected studies were analyzed using the following four steps: word extraction and refinement, keyword extraction, co-occurrence matrix generation, and text network visualization. The results demonstrated that 182 Korean and 2502 international studies were published. The common keywords of Korean and international studies were "kangaroo mother care," "stress," and "child." The keywords of the international studies had more branches linking to other keywords than those of the Korean studies. Thus, the knowledge structure of international studies included diverse concepts. These findings will serve as important guidance for future research worldwide. Furthermore, studies to develop a more comprehensive knowledge structure of international research on premature infants are needed. The knowledge structure of Korean studies mainly included concepts related to mothers. Korean studies regarding hospitalized premature infants and communication with parents need to be conducted.

Use of Smartphone-Based Electronic Medical Records by Nurses in Tertiary Teaching Hospitals.

The adoption of smartphone-based electronic medical records is increasing in the healthcare sector. Nurses are the largest group using mobile electronic medical records. This study examined the system quality, information quality, service quality, usefulness, and ease of using mobile electronic medical records, the effects of the three qualities of the mobile electronic medical records on the usefulness and ease of use, and nurses' preference for using mobile electronic medical records. The participants were 210 nurses using a mobile electronic medical record system for over a month. An instrument modified from existing instruments was used. The data were analyzed using descriptive statistics and multiple regression analysis. The participants perceived the system and information quality more positively than the service quality of the mobile electronic medical records. They perceived the mobile electronic medical records as being useful and easy to use. System quality and information quality significantly affected the perception of the usefulness and ease of using the mobile electronic medical record. They preferred to use it as a means to identify patients' conditions at any time. For user satisfaction and the implications for nursing practice, the usability and functionality of a mobile electronic medical record system should be continuously assessed.

Health Belief Model Factors and Personal Characteristics Associated With COVID-19 Vaccination Behaviors in Adults.

Prior studies have mainly examined factors regarding COVID-19 vaccination intentions. This study investigated the factors associated with COVID-19 vaccination behaviors in Korean adults. A total of 620 adults recruited from a survey company between July and August 2021 completed an online survey asking about their personal characteristics, health beliefs, and COVID-19 vaccination status. The collected data were analyzed using descriptive statistics, Pearson's χ2 test, independent-samples t test, and logistic regression analysis. Less than half the participants received COVID-19 vaccinations, whereas 56.3% did not. The full regression model explained 33.3% of the variance in COVID-19 vaccination status. Age older than 60 years, perception of feeling healthy, presence of chronic diseases, past flu shot experiences, and five health belief model factors were significant factors associated with COVID-19 vaccination behaviors. COVID-19 vaccination intention was the most closely related factor (odds ratio, 12.37; 95% confidence interval, 3.54-43.26; P < .001). Vaccinated participants were more likely than unvaccinated to perceive susceptibility to COVID-19 infection, benefits, self-efficacy, moral responsibility, and subjective norms regarding COVID-19 vaccination. Based on the results, vaccinated and unvaccinated individuals showed different attitudes toward COVID-19 infection and vaccination. This study suggests that COVID-19 vaccination intentions lead to actual vaccination behavior.

Identifying Latent Topics and Trends in Premature Infant-Related Nursing Studies Using a Latent Dirichlet Allocation Method.

This study aimed to identify topics and within-topic core keywords in premature infant-related nursing studies published in Korean and international academic journals using topic modeling and to compare and analyze the trends in Korean and international studies. Journal databases were searched to extract nursing studies involving premature infants from 1998 to 2020. Journal databases included MEDLINE, Web of Science, CINAHL, and EMBASE for international studies and DBpia, the National Digital Science Library, the Korea Citation Index, and the Research Information Sharing Service for Korean studies. Abstracts from the selected 182 Korean and 2502 international studies were analyzed using NetMiner4.4.3e. In results, four similar topics (Korean vs international) were "pain intervention" versus "pain management"; "breast feeding practice" versus "breast feeding"; "kangaroo mother care"; and "parental stress" versus "stress & depression." Two topics that appeared only in the international studies were "infection management" and "oral feeding & respiratory care." Overall, the international studies dealt with diverse topics directly associated with premature. Korean studies mainly dealt with topics related to mothers of premature infants, whereas studies related to premature infants were insufficient. Nursing research in Korea needs to be expanded to research topics addressing premature infants.

Computed tomographic findings may be useful for differentiating small intestinal adenocarcinomas, lymphomas, and spindle cell sarcomas in dogs.

An improved understanding of the CT characteristics for histologically confirmed primary intestinal tumors would be helpful for guiding prognosis and treatment plans in affected dogs. This retrospective, multi-center, analytical study aimed to evaluate the CT characteristics for the differentiation of adenocarcinoma, lymphoma, and spindle cell sarcoma (SCS) in dogs. Thirty-seven dogs who underwent contrast CT and histopathological examinations were included (adenocarcinomas, n = 11; lymphomas, n = 12; SCS, n = 14). Quantitative and qualitative CT parameters, including tumor morphology, contrast enhancement pattern, Hounsfield unit (HU) value, and presence or absence of intraabdominal lymphadenopathy, were evaluated for each included small intestine tumor CT case. Adenocarcinomas tended to show endophytic growth, intestinal obstruction, and a heterogeneous enhancement pattern. Lymphomas tended to show exophytic growth, contrast enhancement of the intestinal tumor mucosal layer, a homogeneous enhancement pattern, and the presence of lymphadenopathies in the abdominal cavity. SCSs tended to show lobulated growth, a large cystic portion within the tumor, a heterogeneous enhancement pattern, a large size with fat stranding sign, and lower HU values in postcontrast images. Cut-off values of the minimum diameter/fifth lumbar vertebral mid-body height (≥5.80; area under the curve [AUC] = 0.97, P < 0.001) and minimum HU value/HU value of the aorta (≤0.26; AUC = 0.96, P < 0.001) were derived to discriminate SCS from the two other tumor types. In conclusion, contrast CT characteristics may be useful in differentiating small intestinal adenocarcinomas, lymphomas, and SCSs in dogs.

Effect of Electronic Medical Record Quality on Nurses' Perceived Usefulness and Ease of Use.

Electronic medical records have been adopted in Korean clinical settings for a few decades. However, there is a lack of studies on the quality, usefulness, and easy use of electronic medical records examined from the perspective of nurses. This study sought the effect of the system quality, information quality, and service quality of an electronic medical record on nurses' perceived usefulness and ease of use of the electronic medical record. A total of 278 nurses from four hospitals completed a self-administered questionnaire using a 5-point Likert scale. The data were analyzed using descriptive statistics and hierarchical multiple regression methods. The results showed that the system, information, and service quality of the electronic medical records explained 36.2% of the variance in perceived usefulness ( F = 51.760, P < .001) and 43.4% of the variance in perceived ease of use ( F = 70.019, P < .001). Thus, these three qualities were significant factors predicting perceived usefulness and ease of use. The close cooperation of stakeholders including administrators, healthcare providers including nurses, and researchers involved in clinical practice will improve electronic medical record quality leading to user-friendly electronic medical record implementation. This study provided statistical interpretations to help in understanding regression analysis.

Nurses' Perceptions of Using Personal Digital Assistants in Tertiary Hospitals.

Personal digital assistants can perform multiple functions such as Internet search, documentation, calculating, and barcode scanning. This study examined nurses' perceptions of personal digital assistants used as a barcode scanner for medication administration, blood transfusions, and blood collection. A total of 236 nurses participated in the survey using the instrument developed by the researchers. The data collected were analyzed using descriptive statistics, one-way analysis of variance, and the Scheffe test. Written responses to the advantages and drawbacks of using personal digital assistants were categorized by meaning. The results showed that the nurses perceived more drawbacks than advantages in using personal digital assistants because of nonworking barcodes, prescription practice requiring additional scanning, poor interfacing between personal digital assistants and the EMR, and frequent Wi-Fi disconnection. The drawbacks resulted in delays in nursing workflow for patient care. Therefore, increasing the availability of barcode scanning for all medications applicable to personal digital assistant use, redesigning the practice of current prescriptions to eliminate additional scanning, and seamless interfacing between personal digital assistants and EMRs should be considered. This enables the nurses to use personal digital assistants more efficiently and effectively for patient care.

Measuring Nurses' Experiences With Unintended Adverse Consequences in EMR Use in Acute Care Settings.

Adverse effects of EMR use have been rarely reported in South Korea. This study examined nurses' experiences with unintended adverse consequences associated with EMR implementation. The participants were 155 nurses using the EMR for patient care in three public hospitals. The statistically tested 21-item instrument and the same 21 open-ended questions were used for data collection. The data collected were analyzed using descriptive statistics and two-way analysis of variance, and the descriptions were grouped by meaning. The participants frequently experienced unintended adverse consequences that resulted from EMR use, and their experiences were organized into 11 subgroups under four dimensions of the unintended consequences instrument including the malfunction and inefficient design of EMR screens dimension (two groups), extra work from EMR implementation dimension (three groups), EMR incompatibility and changes in the prescription pattern dimension (three groups), and patient safety and EMR dependence (three groups). Successful implementation of EMRs is possible when unintended adverse consequences identified by the users are corrected and EMRs are tailored to user needs. Healthcare organizations should provide administrative support, timely technical remedy, and user training to increase user acceptance on a system.

Exploratory Factor Analysis for a Nursing Workaround Instrument in Korean and Interpretations of Statistical Decision Points.

The use of workarounds by nurses is prevalent in clinical settings. Understanding how work processes are adjusted as a result of implementing an electronic medical record is important because of its impact on patient care. The purpose of this study was to conduct an exploratory factor analysis of a 20-item nursing workaround instrument translated into Korean. The responses from 104 nurses were analyzed. Examinations of sample size, factorability of a correlation matrix, the Kaiser-Meyer-Olkin value, the P value of Bartlett test of sphericity, anti-image correlation coefficients, and communality were acceptable to proceed with exploratory factor analysis. The original dimensionality of four groups was retained. However, the number of items loaded onto each group was reduced from five to three. These four factors explained 66% of the total variance between the items. Cronbach's α for the internal consistency reliability of the instrument was .70. The 12-item nursing workaround instrument was specific to an electronic medical record, which was the strongest point of the instrument. Further confirmatory factor analysis of this instrument is needed. This translated instrument is expected to contribute to the proliferation of studies examining nurses' workarounds related to the use of electronic medical records in Korean clinical settings, thereby improving clinical information systems for clinical practice.

Effects of Government-Driven Smartphone Text Messages on Public Compliance With COVID-19 Preventative Measures.

The new pandemic situation caused by a highly infectious virus has prompted the government of many countries to strengthen epidemic prevention measures. An unprecedented action was taken by the Korean government by sending text messages on COVID-19 preventative measures and the movement routes of confirmed-positive persons to the entire nation's smartphones. This study aimed to examine how effective the government-driven smartphone text messages were for public compliance with the measures. A total of 489 participants completed an online questionnaire or a pencil-and-paper questionnaire between September and October 2020. A self-reported questionnaire was used to measure the degree of compliance with the measures, the perceptions of the role of smartphone text messages in compliance with the measures, and the overall feelings toward smartphone text messages. The data were analyzed using descriptive statistics and two-way analysis of variance. The written responses were grouped by meaning. The participants presented a high degree of compliance with the measures and perceived the importance of the role of continuous smartphone text messages in complying with the measures. Positive feelings toward smartphone text messages predominated over negative feelings. Using smartphone text messages in nursing practice is recommended for patients requiring the continuous management of their disease.

Nurses' Electronic Medical Record Workarounds in a Tertiary Teaching Hospital.

The objective of this study was to identify nurses' workarounds related to the use of electronic medical records in a tertiary teaching hospital. A total of 106 nurses (84.8%) using the electronic medical records completed 10-item questionnaires scored on a Likert scale and five open-ended questions with written responses. The numerical data were analyzed by descriptive statistics, and the written descriptions were categorized by meaning. The mean of the scored items ranged from 3.29 to 3.74. Approximately 38% to 50% of the participants reported (very) frequent workflow delays due to the use of the electronic medical records, and 46% to 64% reported (very) frequently using workarounds. Twenty-nine workarounds of the electronic medical records were due to electronic documentation, difficulty accessing the electronic medical records, medication administration, covering physician responsibilities, electronic communication with the physicians, respondents and physicians not skilled in using the electronic medical records, and connection failures between devices or machines and the electronic medical records. Although none of these identified workarounds were intended to be harmful, and certain workarounds were efficient for patient care and workflow, whether patient safety can be jeopardized by workarounds should be considered. This study contributes to the understanding of why and how workarounds occur in the hospital. It will be useful for achieving greater alignment between work contexts and the electronic medical record in the future.

Quality of Online Information Regarding High-Risk Pregnancies.

Health information on the Internet can have a direct effect on healthcare decision-making. However, the quality of information online has seldom been evaluated. This study aimed to assess the quality of online information on high-risk pregnancies provided by English and Korean Web sites. Through a Google search, 30 English and 30 Korean Web sites were selected on January 2 and 3, 2020, respectively, and assessed using DISCERN, a Journal of the American Medical Association, and Health On the Net Foundation code questionnaires. The data assessed were analyzed using descriptive and nonparametric statistical tests. Overall, the information provided by the English Web sites presented higher-quality information than the Korean Web sites. Most Web sites did not provide the sources of the information presented on their Web sites, meet the Journal of the American Medical Association criteria, or provide information on complementarity. Based on our results, nurses need to be competent in assessing the quality of Web sites and the health information presented there, and nursing students need to be prepared to do so as well. Nurses are responsible for educating their patients about the possibility of incorrect information provided by Internet Web sites and informing their patients about reliable Web sites, thus assisting them to make informed decisions regarding their health.

Unintended Consequences and Workarounds of Electronic Medical Record Implementation in Clinical Nursing Practice.

Nurses have experienced unintended consequences and workarounds associated with health information technology implementation. However, examination of this occurrence is rare. This study aimed to examine the unintended consequences and workarounds produced by the implementation of electronic medical record systems in clinical nursing practice. A total of 143 nurses participated in a survey using statistically tested instruments. The data were analyzed using descriptive statistics and a nonparametric test. The descriptive data were analyzed by meaning. The participants experienced unintended consequences and workarounds related to electronic medical record implementation at moderate or high levels based on the responses to questions scored on 5-point Likert scales. The unintended consequences were closely associated with workarounds. The degree of experience with unintended consequences and the use of workarounds differed significantly according to the level of education, job position, and years in nursing practice. The nursing examples of unintended consequences and workarounds were organized into four categories of unintended consequences. By presenting unintended consequences and workarounds together, this study enhances the understanding of the problems encountered in EMR implementation and the action of nurses. Nurses' needs should be considered as an important resource in developing, redesigning, or purchasing and implementing health information technology in healthcare settings.

Nurses' Electronic Medical Record Workarounds in Mental Healthcare Settings.

This study aimed to examine nurses' EMR workarounds in mental healthcare settings. Of the 52 nurses invited to participate in this study, 50 nurses (96.1%) completed the survey using the EMR nursing workaround instrument and open-ended questions. The data collected were analyzed using descriptive statistics and Pearson's correlation coefficients. The descriptive data were grouped into four units including the cases, contributing causes, and consequences of EMR workarounds, and suggestions for improving EMR implementation. The results showed scores above an average of 3.0 in all of the EMR workaround items, indicating the considerable involvement of nurses in EMR workarounds. The workarounds related to EMR use were using the physician's login account for medication access, performing retrospective documentation, performing documentation before an expected busy situation, and seeking and entering information on external medications. The workarounds associated with colleagues unfamiliar with EMR use included waiting for, filling in for, teaching, and assisting unskilled colleagues. This study identified the problems, consequences, and suggestions associated with EMR implementation for psychiatric patient care. This study added useful information for the administrative, technical, and clinical improvement of EMR implementation in mental healthcare practice.

Quality Evaluation of Visual Display Terminal Syndrome Videos Shared on YouTube.

Visual display terminal syndrome is a health problem that occurs when an individual looks at a visual display terminal for a long time. This study aimed to evaluate the quality of YouTube videos on visual display terminal syndrome. YouTube was searched using the keywords "visual display terminal syndrome" and "a prolonged user of a computer or smartphone" on October 16, 2019. A total of 45 videos were evaluated using DISCERN and the Journal of the American Medical Association scoring systems. The variables extracted from the videos were the uploading agency; content; presentation format; days since upload; the number of views, likes, dislikes, and comments; and the video power index. The mean DISCERN and Journal of the American Medical Association scores were 35.64 and 3.08 points, respectively, indicating that the information on visual display terminal syndrome in YouTube videos was inaccurate and unreliable. The major reason for the low quality of the videos was that the sources of information presented in the videos were not provided. The DISCERN and Journal of the American Medical Association scores showed significant differences in the uploading agency and presentation format variables. Nurses must be familiar with evaluating the quality of videos presenting health information. Guidelines informing patients that YouTube might provide misinformation about health need to be developed.

Moderating effects of socio-ecological factors on the relationship between adolescent exposure to media violence and attitudes towards school bullying.

AIMS: To examine the moderating effects of individual, family, and social factors on the relationship between adolescent exposure to media violence and attitudes towards school bullying. DESIGN: A cross-sectional study. METHODS: A total of 473 middle and high school students participated in a self-reported survey between August and October 2016. Self-reported questionnaires were used to measure perceived aggression, resilience, parental violence experience, parenting styles, satisfaction with school life, teacher attitudes towards school bullying, media violence exposure, and adolescent attitudes towards school bullying. The data were analyzed using descriptive statistics and hierarchical multiple regression. RESULTS: Resilience (an individual factor; ß = -0.48, p = .049) and parenting styles (a family factor; ß = -0.77, p = .045) moderated the negative influence of media violence exposure on adolescent attitudes towards school bullying. The findings indicated that higher individual resilience and parents with more positive parenting styles could reduce the harmful effects of media violence exposure on adolescent attitudes towards school bullying. The teachers' attitudes towards school bullying (a school factor) contributed to predicting the adolescents' attitudes towards school bullying. However, no moderating effect of school factors was found. CONCLUSION: Resilience and parenting styles are important socio-ecological factors influencing the relationship between adolescent exposure to media violence and attitudes towards school bullying. IMPACT: Three types of intervention programmes can be suggested based on the results of this study. Reinforcing individual resilience and positive parenting styles should be considered important in developing intervention programmes targeted at eliminating the adverse effects of media violence exposure. Intervention programmes to develop parenting styles to increase the resilience of adolescents can also be considered. Lastly, programmes to screen for adverse outcomes of media violence exposure, low resilience, and poor parenting styles need to be developed.

Implementation of an Electronic Nursing Record for Nursing Documentation and Communication of Patient Care Information in a Tertiary Teaching Hospital.

Despite the fact that implementing an electronic nursing record has become an everyday event for nurses, little is known about which type of documentation used in an electronic nursing record is better for nursing practice. The aim of this exploratory study was to identify the most suitable type of electronic nursing documentation that nurses used to record care and communicate with clinicians. Participants consisted of 118 nurses and 12 physicians. Researchers developed a self-report questionnaire of 17 items about electronic nursing record use for documentation and communication of patient care information. Data were analyzed using descriptive statistics to calculate frequencies and percentages. The χ2 test was used to identify differences in responses by demographic and clinical characteristics of participants. Bar charts were used to identify response patterns. Results showed that semistructured nursing documentation was the most preferred for care documentation and communication of patient information. Nurses did not always use the electronic nursing record to communicate patient care-related information. This study adds empirical knowledge about which type of documentation used in the electronic nursing record works well, what improvement is needed for better nursing practice, and whether the electronic nursing record has been used for communication.

Adaptation and validation of the health belief model scale for colorectal cancer screening.

Korea has the second highest incidence of colorectal cancer in the world. Instruments that are culturally and contextually sensitive, as well as valid and reliable, for determining health beliefs regarding colorectal cancer screening are essential for obtaining accurate information. The purpose of this study was to adapt and validate the health belief model scale for Koreans regarding colorectal cancer and fecal occult blood test utilization. Individual and cognitive interviews (also known as cognitive debriefing) with 33 Koreans, expert reviews with seven nursing practitioners and professors, and a pilot test with 18 Koreans were conducted to make the existing health belief model scale culturally and contextually sensitive. Subsequently, a cross-sectional survey with 728 Koreans aged >50 years was conducted. Exploratory and confirmatory factor analyses of the construct validity and internal consistency reliability supported the adapted health belief model scale. The adapted and validated health belief model scale in this study could contribute to the assessment of health beliefs regarding the fecal occult blood test among Koreans with a greater degree of accuracy with respect to Korean culture and context.

Implementation of Structured Documentation and Standard Nursing Statements: Perceptions of Nurses in Acute Care Settings.

Nurses implement structured documentation using standardized nursing terminologies in computerized healthcare settings. Nurses' perceptions, shaped by their experiences of implementing such documentation, are an important indicator for the documentation system's optimal maintenance and improvement. The purpose of this study was to describe perceptions of nurses using SYSTEM featuring standard nursing statements and structured documentation. A quantitative cross-sectional study design was used. A total of 42 nurses from a tertiary teaching hospital participated in this study. A researcher-developed survey questionnaire included seven questions asking nurses' perceptions of nursing process phases and SYSTEM's usefulness, effectiveness, necessity, assistance in decision making, and suggestions for SYSTEM improvement. As results, the assessment phase was perceived to be the most necessary, while the planning phase was perceived to be the most unnecessary. Perceived disadvantages were decreased patient care time, increased charting time, and standard nursing statements not covering diverse patients' conditions. These disadvantages conflicted with perceived advantages. For successful implementation of electronic nursing records, stakeholders at clinical, information technology, and administrative levels should cooperate closely to address adverse consequences from implementation of structured documentation and standardized nursing terminologies.
