Purpose: This study aimed to identify the factors influencing nurses’ perceptions of the disclosure of patient safety incidents in tertiary hospitals. Methods: As a descriptive study, data were collected from 315 nurses working in two tertiary hospitals in Busan via structured self-report questionnaires from June 28 to September 3, 2023, through an online survey. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson’s correlation coefficients, and hierarchical regression analysis with SPSS/WIN 27.0. Results: Analysis was conducted by controlling for the characteristics of the study participants, which revealed significant differences in their perceptions of the disclosure of patient safety incidents. Ethical nursing competence (β=.30, p<.001) and patient safety culture (β=.15, p=.012) were significant influencing factors on the perception of such disclosure, and the explanatory power of the regression model was 21.0% (F=14.63, p<.001). Conclusion To enhance the aforementioned perception among nurses in tertiary hospitals, healthcare institutions should provide learning opportunities to improve their ethical nursing competence. Fostering an organizational culture that promotes and encourages open disclosure of patient safety incidents is also essential.

Background: While individuals exposed to radiation in hospitals are typically registered as radiation workers, with regulated exposure levels, many interns and residents who are not registered as radiation workers are occupationally exposed to radiation. This study aimed to assess the current status and awareness of radiation exposure and related protective practices among interns and residents. Methods: An online survey was conducted nationwide from June 3 to June 16, 2023, engaging 262 interns and 799 residents. Descriptive analyses were conducted to summarize the status of occupational radiation exposure and radiation protection practices. Results: Approximately 6% of interns and 18% of residents reported receiving personal dosimeters, and 6% and 20%, respectively, were registered as radiation workers. In contrast, compliance with personal radiation protection equipment, such as lead aprons and thyroid shields, exceeded 85% during tasks involving radiation exposure. On average, interns spent 7 months (standard deviation [SD], 2.1) and residents 8.1 months (SD, 4.8) in main departments with potential radiation exposure. While overall safety performance showed improvement, the provision of personal dosimeters and radiation worker registration remained low (14.7%, 16.6%). Conclusion Despite improvements in radiation protection education and the provision of personal protective equipment, the registration rate for radiation workers among interns and residents remains low. Ensuring these medical professionals are registered and managed as radiation workers is crucial for prioritizing their safety and well-being.

Background: Chronic atrophic gastritis causes hypochlorhydria, hypergastrinemia, and malabsorption of nutrients, leading to lower bone mineral density. The few studies that investigated the association between chronic atrophic gastritis and bone mineral density have reported inconsistent findings. As such, the present study assessed the association between chronic atrophic gastritis and bone mineral density among a large sample of women >40 years of age in Korea. Methods: Data from 8,748 women >40 years of age who underwent esophagogastroduodenoscopy and bone densitometry were analyzed. Chronic atrophic gastritis was diagnosed using esophagogastroduodenoscopy. Bone mineral density of the lumbar vertebrae (L), femur neck, and femur total, measured using dual-energy X-ray absorptiometry, were the primary outcome variables. Low bone mineral density, which could be diagnosed as osteoporosis or osteopenia, was defined and analyzed as a secondary outcome. Linear regression was used to calculate adjusted mean values of bone mineral density. The association between low bone mineral density and chronic atrophic gastritis was analyzed using multiple logistic regression. Results: The adjusted mean bone mineral density for L1–L4 was 1.063±0.003, femur neck (0.826±0.002), and femur total (0.890±0.002) were significantly lower in patients with chronic atrophic gastritis than others (1.073±0.002, 0.836±0.001, 0.898±0.002, respectively; all P<0.01). Women with chronic atrophic gastritis exhibited an increased likelihood for osteopenia or osteoporosis, even after adjusting for age and other confounding factors (odds ratio, 1.25; 95% confidence interval, 1.13–1.40; P<0.01). However, subgroup analysis revealed statistical significance only in postmenopausal women (odds ratio, 1.27; P<0.001). Conclusion Chronic atrophic gastritis was associated with lower bone mineral density and a higher risk for osteopenia or osteoporosis among postmenopausal women.

Objectives: Aquatic therapy is a significant intervention method for both patients and healthy individuals. However, in clinical practice, quantitative measurements are rarely applied in aquatic therapy due to the disadvantages of submerging expensive instruments in water. In this study, we used readily available smartphones and armbands to measure leg segments and joint angles during aquatic gait and evaluated the reliability of these measurements. Methods: Waterproof smartphones were strapped to the trunk, thighs, and shanks of 19 healthy young adults using armbands. The angles of the trunk, thigh, and shank segments were measured during aquatic gait. The measurements were repeated 1 day later. The data were analyzed to obtain the angles of the hip and knee joints. Results: Measurement repeatability, calculated using the intraclass correlation coefficient (ICC), was the highest for the shank segment range of motion (ROM) (first 46.79° ± 5.50°, second 50.12° ± 9.98°, ICC = 0.78). There was high agreement in trunk segment ROM (first 6.36° ± 1.42°, second 4.29° ± 1.83°, ICC = 0.73), thigh segment ROM (first 33.49° ± 5.18°, second 37.31° ± 8.70°, ICC = 0.62), and knee joint ROM (first 52.43° ± 11.26°, second 62.19° ± 16.65°, ICC = 0.68) and fair agreement in hip joint ROM (first 34.60°±4.71°, second 37.80° ± 7.84°, ICC = 0.59). Conclusions Smartphones can be used to reliably measure leg segments and joint angles during aquatic gait, providing a simpler method for obtaining these measurements and enabling the wider use of aquatic motion analysis in clinical practice and research.

Economic evaluations in the healthcare are used to assess economic efficiency of pharmaceuticals and medical interventions such as diagnoses and medical procedures. This study introduces the main concepts of economic evaluation across its key steps: planning, outcome and cost calculation, modeling, cost-effectiveness results, uncertainty analysis, and decision-making. When planning an economic evaluation, we determine the study population, intervention, comparators, perspectives, time horizon, discount rates, and type of economic evaluation. In healthcare economic evaluations, outcomes include changes in mortality, the survival rate, life years, and quality-adjusted life years, while costs include medical, non-medical, and productivity costs. Model-based economic evaluations, including decision tree and Markov models, are mainly used to calculate the total costs and total effects. In cost-effectiveness or costutility analyses, cost-effectiveness is evaluated using the incremental cost-effectiveness ratio, which is the additional cost per one additional unit of effectiveness gained by an intervention compared with a comparator. All outcomes have uncertainties owing to limited evidence, diverse methodologies, and unexplained variation. Thus, researchers should review these uncertainties and confirm their robustness. We hope to contribute to the establishment and dissemination of economic evaluation methodologies that reflect Korean clinical and research environment and ultimately improve the rationality of healthcare policies.

In this study, the Search Your Mind (S.Y.M., 心) project aimed to collect prospective digital phenotypic data centered on mood and anxiety symptoms across psychiatric disorders through a smartphone application (app) platform while using both centralized and decentralized research designs: the centralized research design is a hybrid of a general prospective observational study and a digital platform-based study, and it includes face-to-face research such as informed written consent, clinical evaluation, and blood sampling. It also includes digital phenotypic assessment through an application-based platform using wearable devices. Meanwhile, the decentralized research design is a non-face-to-face study in which anonymous participants agree to electronic informed consent forms on the app. It also exclusively uses an application-based platform to acquire individualized digital phenotypic data. We expect to collect clinical, biological, and digital phenotypic data centered on mood and anxiety symptoms, and we propose a possible model of centralized and decentralized research design.
