Ocular vestibular-evoked myogenic potential assists in differentiation of multiple system atrophy from Parkinson's disease.

Vestibular-evoked myogenic potentials (VEMPs) can help assess otolithic neural pathway in the brainstem that may also participate in cardiovascular autonomic function. Parkinson's disease (PD) is associated with altered VEMP responses; however, the association between VEMP abnormalities and multiple system atrophy (MSA) remains unknown. Therefore, we compared the extent of otolith dysfunction using ocular (oVEMP) and cervical VEMP (cVEMP) between MSA and PD. We analyzed the clinical features and VEMP and head-up tilt table test (HUT) findings using the Finometer in 24 patients with MSA and 52 with de-novo PD, who had undergone neurotologic evaluation in a referral-based university hospital in South Korea from January 2021 to March 2023. MSA was associated with bilateral oVEMP abnormality (odds ratio [95% confidence interval] = 9.19 [1.77-47.76], p=0.008). n1-p1 amplitude was negatively correlated with Unified Multiple System Atrophy Rating Scale I-II scores in patients with MSA (r=-0.571, p=0.033), whereas it did not correlate with Movement Disorder Society-Unified Parkinson's Disease Rating Scale-III scores in patients with PD (r=-0.051, p=0.687). n1 latency was negatively correlated with maximum changes in systolic blood pressure within 15 s during HUT in patients with PD (r=-0.335, p=0.040) but not in those with MSA (r=0.277, p=0.299). In conclusion, bilaterally abnormal oVEMP responses may indicate the extent of brainstem dysfunction in MSA. oVEMP reflects the integrity of otolith-autonomic interplay, reliably assists in differentiating between MSA and PD, and helps infer clinical decline.

The incidence of periungual desquamation and thrombocytosis in Kawasaki disease and the importance of systematic observation in the subacute phase.

Periungual desquamation and thrombocytosis are characteristic of the subacute phase of Kawasaki disease (KD). However, accurate observations of periungual desquamation and thrombocytosis are lacking. This retrospective study included patients with acute-phase KD who received treatment at seven affiliated university hospitals in Korea between 2015 and 2017. Data were extracted from an anonymized registry established by the Korean Society of Kawasaki Disease. We investigated whether the findings of patients observed according to a set protocol until the subacute stage (group I) were different from those of patients observed without the use of a protocol (group II). A total of 879 patients with KD were included in the analysis. Periungual desquamation was observed in 85% and 12.7% of patients in groups I and II, respectively. Thrombocytosis was observed in 76.7% and 44.7% of patients in groups I and II, respectively. Furthermore, compared to the initial test, the platelet counts of patients increased 100% and 67.9% in group I and II, respectively. When incomplete KD was defined only by the main symptoms during the acute stage and the diagnostic criterion of periungual desquamation during the subacute stage was excluded, the significant difference in the incidence of incomplete KD between groups I and II was no longer apparent. Performing regular and detailed observations has resulted in a higher incidence of periungual desquamation and thrombocytosis during the subacute phase of KD than those reported in recent studies. This indicates that until now, we have been neglecting the observation of symptoms and signs during the subacute phase. Regular monitoring during this period can also aid in differentiating suspected cases of KD and facilitate appropriate follow-up of complications.

Intraoperative neuromonitoring during thyroidectomy does not decrease vocal cord palsy risk, but the cumulative experience of the surgeon may.

To evaluate the influence of intraoperative neuromonitoring (IONM) on vocal cord palsy (VCP) rates and assess the temporal trends in VCP rates. The subjects of this retrospective study were patients who underwent thyroidectomy for thyroid cancer between March, 2014 and June, 2022, at a university hospital in Korea. We compared VCP rates between the non-IONM and IONM groups and analyzed the risk factors for VCP and VCP rates over time. A total of 712 patients were included in the analysis. The rates of transient and permanent VCP did not differ significantly between the non-IONM and IONM groups. Transient VCP occurred in 4.6% and 4.3% patients (p = 0.878) and VCP was permanent in 0.7% and 0.4% patients (p = 0.607) in the non-IONM and IONM groups, respectively. Among the nerves at risk, transient damage occurred in 2.8% and 3.0% patients (p = 0.901), and permanent damage occurred in 0.4% and 0.3% (p = 0.688), respectively. Multivariate analysis revealed no significant risk factors for VCP. There was a significant decreasing trend in VCP rates over time as the cumulative number of cases increased (p = 0.017). IONM did not reduce the risk of VCP significantly. However, the declining trend of VCP rates suggests that the surgeon's experience may mitigate VCP risk.

Enhancing ACLS training effects through video-assisted boosting methods: A comparative analysis of self-simulation and model simulation videos

AimsTo assess the impact of learner-participation and instructor-led simulation videos on nurses’ CPR skills, focusing on iterative learning to boost proficiency in ACLS. BackgroundAdvanced cardiac life support (ACLS) training is crucial for nurses, especially to improve cardiopulmonary resuscitation (CPR) proficiency, for which an effective training strategy is needed. DesignA quasi-experimental, pretest–posttest design was implemented to assess the impact of self-simulation and model simulation videos on sustaining CPR education. MethodsThe research was carried out at a university hospital in Korea from August 2021 to July 2022. A total of 110 nurses were allocated into three groups based on the building of their workplace in the hospital. Each group watched training videos at 4-month intervals after the simulation training. The self-video group viewed simulations featuring their participation, while the model video group watched instructor-led simulations. A comparison group participated in the simulations without subsequent video boosting. ResultsBoth the self-video and model video groups exhibited significantly superior ACLS performance compatred with the comparison group at both four months (H = 70.33, p <.001) and eight months (H = 81.52, p <.001) following the intervention, with large effect sizes (self-video vs. comparison: d = 4.73 at four months, d = 12.54 at eight months; model video vs. comparison: d = 4.53 at four months, d = 11.01 at eight months). ACLS knowledge scores also significantly increased over time in both intervention groups (self-video: χ² = 22.09, p <.001; model video: χ² = 24.13, p <.001), but not in the comparison group (χ² = 3.75, p =.153). There were no significant differences among the groups in terms of CPR self-efficacy or stress at either time point. ConclusionSupplementary training using simulation videos is an effective method for maintaining and enhancing nurses’ ACLS competency, offering a sustainable approach to repetitive CPR training. This study underscores the value of incorporating recorded simulation videos in clinical training, offering insights into efficient methods for continuous learning and CPR proficiency among nursing professionals.

Association of menopausal status with body composition and anthropometric indices in Korean women.

Menopause induces various health problems and is associated with obesity, but the association between menopausal status and obesity is unclear due to several confounding factors, such as aging and reduced physical activity. The objective of this study was to examine the association of menopausal status with anthropometric indices and body composition indices in South Korean women. In this cross-sectional study, a total of 734 subjects (297 postmenopausal women, 437 premenopausal women) from five university hospitals in South Korea were included. A binary logistic regression analysis was performed to examine the association of menopause with anthropometric indices and body composition indices. Height, body mass index, waist-to-height ratio, waist-to-hip ratio, and neck, armpit, chest, rib, waist, iliac, and hip circumferences were associated with menopausal status in the crude analysis, but these associations disappeared in the adjusted models. Among the body composition indices, menopausal status was strongly associated with total body water, skeletal muscle mass, body fat mass, and body fat percentage in the crude analysis. However, the associations with body fat mass and body fat percentage disappeared in the adjusted models. Only the associations with total body water and skeletal muscle mass remained in the adjusted models. Most of the anthropometric indices and body composition indices were not associated with menopausal status, but total body water and skeletal muscle mass were significantly lower in postmenopausal women than in premenopausal women.

ASSOCIATION BETWEEN ORTHOSTATIC HYPERTENSION AND FRAILTY AMONG OLDER PATIENTS WITH HYPERTENSION

Objective: Frailty frequently co-exists with hypertension in older patients. We aimed to evaluate the association between frailty and positional change in blood pressure, especially orthostatic hypertension. Design and method: Participants were recruited from 12 University hospitals in South Korea. Using a digital device, trained research nurses measured blood pressure in the supine and standing positions. Physical frailty was evaluated using the Korean version of the FRAIL questionnaire, gait speed, and hand-grip strength. Orthostatic hypertension was defined as a &gt;= 20-mmHg increase in systolic blood pressure within 3 min of standing and upright systolic blood pressure of &gt;= 140 mmHg. Results: We analyzed the data of 2,065 participants who had been enrolled until December 31, 2022. The mean age was 73.2 ± 5.6 years and 52.0% were female. The mean blood pressure was 137.1 ± 14.9 / 75.1 ± 9.7 mmHg. Among the participants, 1,886 (91.3%) showed normal response after standing, but 94 (4.6%) had orthostatic hypertension, and 85 (4.1%) had orthostatic hypotension. Orthostatic hypertension was associated with female sex, obesity, cognitive function, physical frailty, and lower quality of life (QOL). In the multivariable analysis, body mass index and frailty status were independently associated with orthostatic hypertension. Conclusions: Orthostatic hypertension is associated with physical frailty, cognitive impairment, and low QOL in older patients with hypertension. Therefore, evaluation of orthostatic blood pressure changes to confirm orthostatic hypertension or hypotension in frail older adults will serve as an important diagnostic procedure in vulnerable patients. Further studies are required to identify the underlying mechanisms of this association.

Association Between Orthostatic Hypertension and Frailty Among Older Patients With Hypertension.

Frailty frequently coexists with hypertension in older patients. We aimed to evaluate the association between frailty and positional change in blood pressure, especially orthostatic hypertension. Participants were recruited from 12 University hospitals in South Korea. Using a digital device, trained research nurses measured blood pressure in the supine and standing positions. Physical frailty was evaluated using the Korean version of the FRAIL questionnaire, gait speed, and handgrip strength. Orthostatic hypertension was defined as a ≥20-mm Hg increase in systolic blood pressure within 3 minutes of standing and upright systolic blood pressure of ≥140 mm Hg. We analyzed the data of 2065 participants who had been enrolled until December 31, 2022. The mean age was 73.2±5.6 years, and 52.0% were female. The mean blood pressure was 137.1±14.9/75.1±9.7 mm Hg. Among the participants, 1886 (91.3%) showed normal response after standing, but 94 (4.6%) had orthostatic hypertension, and 85 (4.1%) had orthostatic hypotension. Orthostatic hypertension was associated with female sex, obesity, cognitive function, physical frailty, and lower quality of life. In the multivariable analysis, body mass index and frailty status were independently associated with orthostatic hypertension. Orthostatic hypertension is associated with physical frailty, cognitive impairment, and low quality of life in older patients with hypertension. Therefore, evaluation of orthostatic blood pressure changes to confirm orthostatic hypertension or hypotension in frail older adults will serve as an important diagnostic procedure in vulnerable patients. Further studies are required to identify the underlying mechanisms of this association.

Differences in patient-reported and clinical characteristics by age group in adults with type 2 diabetes.

The global burden of type 2 diabetes (T2D) is growing, and the age of onset is widening, resulting in increasing numbers of young adults and elderly patients with T2D. Age-specific diabetes care needs have yet to be fully explored. This study examined (1) differences in patient-reported and clinical characteristics by age group and (2) the effect of age on two proxy measures assessing psychological health and self-care adherence after adjusting for potential mediators. A cross-sectional, correlational design was used. Adults with type 2 diabetes (T2D) were recruited from a university hospital in Korea between 2019 and 2020. Participants were divided into four groups based on years of age (40s and younger group [n = 27]; 50s group [n = 47]; 60s group [n = 54]; and 70s and older group [n = 48]) to compare patient-reported and clinical characteristics. Chi-square tests, ANOVA, Kruskal-Wallis tests, and logistic regression analysis were performed to assess group differences and effect of age on psychological health and self-care adherence. Of 178 participants, two-thirds were men (n = 114; 64.41%). The mean ages in the 40s and younger, 50s, 60s, and 70s and older groups were 39.4, 54.7, 63.9, and 76.0 years, respectively. There were significant differences in patient-reported and clinical characteristics by age group. The youngest group reported the poorest psychological health and self-care behaviors. Although the oldest group showed the poorest physical functioning, this group also showed the highest self-care adherence and the best psychological health. Regarding clinical characteristics, traditional diabetes-related blood test results showed no significant group differences. Age-specific diabetes care needs were identified in adults with T2D. Interventions to improve psychological health and priming effects of behavioral adherence need to be developed. Furthermore, meticulous investigation to detect potential complications early is essential in adults with T2D.

GCN-assisted attention-guided UNet for automated retinal OCT segmentation

With the increase in the aging population of many countries, the prevalence of neovascular age-related macular degeneration (nAMD) is expected to increase. Morphological parameters such as intraretinal fluid (IRF), subretinal fluid (SRF), subretinal hyperreflective material (SHRM), and pigment epithelium detachment (PED) of spectral-domain optical coherence tomography (SD-OCT) images are vital markers for proper treatment of nAMD, especially to get the information of treatment response to determine the proper treatment interval and switching of anti-vascular endothelial growth factor (VEGF) agents. For the precise evaluation of the change in nAMD lesions and patient-specific treatment, quantitative evaluation of the lesions in the OCT volume scans is necessary. However, manual segmentation requires many resources, and the number of studies of automatic segmentation is increasing rapidly. Improving automated segmentation performance in SD-OCT visual results requires long-range contextual inference of spatial information between retinal lesions and layers. This paper proposes a GAGUNet (graph convolution network (GCN)-assisted attention-guided UNet) model with a novel global reasoning module considering these points. The dataset used in the main experiment of this study underwent rigorous review by a retinal specialist from Konkuk University Hospital in Korea, contributing to both data preprocessing and validation to ensure a qualitative assessment. We conducted experiments on the RETOUCH dataset as well to demonstrate the scalability of the proposed model. Overall, our model demonstrates superior performance over the baseline models in both quantitative and qualitative evaluations.

Developing and evaluating an evidence-based practice research competency enhancement program for clinical nurses in Korea: a pilot study

BackgroundEvidence-based practice (EBP) is crucial for delivering high-quality healthcare and effective self-care. Enhancing clinical nurses’ research competencies through structured mentorship is key to the widespread application of EBP. This study evaluated a newly developed Research Competency Enhancement Program (RCEP), aimed at bolstering EBP among experienced nurses.MethodsConducted in a tertiary university hospital in Korea, this single-group study employed a pretest-post-test design and a mixed-methods approach. The RCEP involved 11 experienced clinical nurses in an 8-week intervention, featuring mentor-led workshops, interactive sessions, and resource-driven activities. Data were collected using the Evidence-Based Practice Beliefs Scale (EBPB), the Evidence-Based Practice Attitude Scale (EBPA), and the Research Practice Ability (RPA) tool, alongside qualitative feedback. These measures assessed the program’s feasibility, acceptability, and preliminary effectiveness.ResultsThe quantitative analysis indicated significant improvements in research competency post-intervention. Mean scores on the EBPB and RPA scales increased (Z = -2.53, p = .011; Z = -2.66, p = .008). Participants described the RCEP as inspirational and challenging, creating an environment conducive to research. Facilitators included mentor support and innovative learning tools, while barriers were internet connectivity and scheduling conflicts. Suggestions for improvement included more hands-on sessions, small team collaborations, and integration with academic institutions.ConclusionThe RCEP, facilitated by EBP mentors, significantly improved the research competencies and attitudes of clinical nurses towards EBP. The study underscores the importance of continual RCEP refinement, integrating structured, interactive, and collaborative elements to further empower nurses in evidence-based practice. The program shows promise in enhancing research competencies and fostering a commitment to EBP in clinical settings.

A Survey on Situation-related Communication Educational Needs for Novice Intensive Care Unit Nurses

Purpose : This study sought to investigate novice nurses’ communication education needs in the intensive care unit (ICU) using Importance-Performance Analysis (IPA) and Borich’s need assessment model. This study identified communication challenges in clinical settings to develop a simulation program that enhances communication competencies based on educational requirements.Methods : A descriptive research design and a self-report questionnaire were used. The latter was developed and administered to 121 novice nurses with less than one year of experience in the ICU at various university hospitals in Korea. Data were collected via the online open chatroom from June 24th to July 28th, 2023. The communication education needs were identified using descriptive statistics, t-tests, IPA, and Borich’s needs assessment model. Text analysis was used to categorize the participants’ communication experience.Results : The results revealed that “communication with physicians,” “communication with patients,” and “communication with nurse on another shift” domains contained the most substantial educational needs for novice nurses working in the intensive care units.Conclusion : The results provide fundamental data for developing and enhancing customized communication education programs for novice ICU nurses. This valuable information could help ICU nurses and educators improve new nurses’ communication skills, which would ultimately contribute to the advancement of nursing education and clinical practice.

A predictive model for medication adherence in older adults with heart failure.

Although many studies have examined the predictors of medication adherence (MA), further empirical research is required to clarify the best model for predicting MA for older adults with heart failure (HF). Thus, we hypothesized a model in which information (knowledge), motivation (social support and depressive symptoms), and behavioural skills (barriers to self-efficacy) would be associated with MA in patients with HF. Using a cross-sectional survey, 153 adults aged ≥ 65 years taking medication for HF were recruited from a university hospital in Korea. Data were collected based on the information-motivation-behavioural skills (IMB) model constructs and MA. In the hypothesized path model, self-efficacy was directly related to MA (β = -0.335, P = 0.006), whereas social support was indirectly related to MA through self-efficacy (β = -0.078, P = 0.027). Depressive symptoms were directly related to MA (β = 0.359, P = 0.004) and indirectly related to MA through self-efficacy (β = 0.141, P = 0.004). The hypothesized MA model showed a good fit for the data. Knowledge, social support, and depressive symptoms accounted for 44.3% of the variance in self-efficacy (P = 0.004). Left ventricular ejection fraction, knowledge, social support, depressive symptoms, and self-efficacy explained 64.4% of the variance in MA (P = 0.004). These results confirmed the IMB model's suitability for predicting MA in older adults with HF. These findings may guide and inform intervention programmes designed to alleviate depressive symptoms in older adults with HF and enhance their HF knowledge, social support, and self-efficacy, with the ultimate goal of improving their MA.

Ocular motor and vestibular dysfunction in central nervous system lymphoma.

Diagnosis of lymphoma involving the central nervous system (CNS) is challenging. This study aimed to explore the abnormal vestibular and ocular motor findings in CNS lymphoma. A retrospective search of the medical records identified 30 patients with CNS lymphoma presenting ocular motor and vestibular abnormalities from four neurology clinics of university hospitals in South Korea (22 men, age range 14-81 years, mean 60.6 ± 15.2). The demographic and clinical features and the results of laboratory, radiological and pathological evaluation were analyzed. Patients presented with diplopia (13/30, 43%), vestibular symptoms (15/30, 50%) or both (2/30, 7%). In 15 patients with diplopia, abnormal ocular motor findings included ocular motor nerve palsy (n = 10, 67%), internuclear ophthalmoplegia (n = 2, 13%), external ophthalmoplegia (n = 2, 13%) and exophoria (n = 1, 7%). The vestibular abnormalities were isolated in 14 (82%) of 17 patients with vestibular symptoms and included combined unilateral peripheral and central vestibulopathy in three from lesions involving the vestibular nuclei. CNS lymphoma involved the brainstem (53%), cerebellum (33%), leptomeninges (30%), deep gray nuclei (23%) or cranial nerves (17%). Two patients showed the "double-panda" sign by involving the midbrain. This study expands the clinical and radiological spectra of CNS lymphoma. Neuro-ophthalmological and neuro-otological evaluation may guide the early diagnosis of CNS lymphoma.

P630 Identification of specific cell subsets related to treatment response after anti-tumor necrosis factor use in Korean ulcerative colitis patients using single cell RNA sequencing: a preliminary study

Abstract Background The breakdown of the epithelial barrier and mucosal homeostasis plays an important role in the development of ulcerative colitis (UC). Recently, single-cell RNA sequencing (scRNA-seq) has been performed to better understand the gene expression patterns and the characteristics of cells in intestine of UC patients. However, there is a lack of studies focus on Asian UC patients. The aim of this preliminary study was to identify the relevant cellular subsets related to treatment response after anti-tumor necrosis factor (anti-TNF) use in Korean UC patients using scRNA-seq. Methods This prospective study was conducted two University hospitals in Korea. We performed scRNA-seq on sigmoid colon tissue samples collected from one healthy control and nine biologic naïve UC patients scheduled to use anti-TNF due to lack of response to conventional therapy. All mucosal biopsies from active moderate to severe UC were collected at baseline (n=9) and at 52 weeks follow-up after anti-TNF use (n=2), at which time treatment response was assessed. Treatment responder was defined as those with sustained clinical remission (a partial Mayo score of ≤2 with no subscore &amp;gt;1 and a rectal bleeding subscore of 0) at 52 weeks. Results After processing the scRNA-seq data, 13 clusters were discovered and cell clusters were annotated using colon marker gene. Among nine patients, two patients who underwent response evaluation at 52 weeks after anti-TNF use were treatment responder. The normalized proportion of cluster 1 (stem cell-like cluster) in 52 weeks follow-up tissue samples after anti-TNF use was shown to be decreased significantly (p-value=0.03) from that found in the disease tissue samples. A decrease in the proportion of cell cluster 1 from disease tissue samples’ initial average percentage (30.6%) down to an average of 4.8% in the follow-up tissue samples is quite substantial (p-value=0.03). This decrease signifies a notable change in the composition of this specific cell cluster post-anti-TNF treatment. Moreover, reaching a level close to that of the healthy tissue sample (2.7%) suggests a potential restoration of this cell cluster's proportion towards a healthier state (Figure 1). Conclusion In Korean UC patients, this information should be crucial in understanding the impact of anti-TNF treatment on the cellular composition or behavior of this stem cell-like cluster, suggesting a potential effect of anti-TNF treatment on this particular cell population.

Post-COVID-19 Vaccination Myocarditis: A Histopathologic Study on a Monocentric Series of Six Cases.

Many reports on the development of myocarditis following coronavirus disease 2019 (COVID-19) vaccination (PCVM) have emerged. However, only a few case studies have investigated endomyocardial biopsy (EMB) results. This study describes the clinicopathologic features of PCVM. We surveyed all hospitalized patients in a single university hospital in Korea and identified six cases of PCVM. All six patients underwent EMB, five of whom were men aged 15-85 years. All patients developed cardiac dysfunction. Among these patients, two had mild disease without sequelae, whereas the other four had dilated cardiomyopathy with depressed cardiac function. All six cases demonstrated lymphohistiocytic myocarditis. Two of our cases fulfilled the criterion of CD3+ T lymphocytes > 7 cells/mm2 (Case nos. 3 and 6), while the remaining four cases did not fulfill the Dallas criteria. In conclusion, most PCVM cases showed mild degree inflammation histopathologically, and some cases could not fulfill the Dallas criteria and were classified as borderline myocarditis.

Anxiety Symptoms and Associated Psychological and Job-Related Factors Among Hospital Nurses.

Recently, burnout and mental health issues regarding nurses are reported increasingly. This study aimed to investigate the prevalence of anxiety symptoms among hospital nurses and determine their association with psychological and job-related factors. Data on demographics, job-related characteristics, burnout, Type A behavior patterns, self-esteem, and happiness were collected from 515 nurses working at a university hospital in Korea. Anxiety symptoms were assessed using the anxiety subscale of the Hospital Anxiety and Depression Scale, with scores of 8 or higher indicating the presence of anxiety symptoms. Demographic, job-related, and psychological factors were compared according to the presence of anxiety. Logistic regression was conducted to identify factors associated with anxiety symptoms. Two hundred and four (39.6%) participants had anxiety symptoms. Self-esteem and happiness were associated with a lower risk of anxiety symptoms, whereas burnout was associated with a higher risk of anxiety symptoms. Furthermore, being female, having a career of less than five years, and requiring counseling due to stress were associated with a higher risk of anxiety symptoms. Being younger, female, or a basic nurse; having a career of less than five years; partaking in shift work; experiencing job dissatisfaction; requiring counseling due to stress; being exposed to higher levels of burnout; and having lower levels of self-esteem and happiness were all found to be significantly correlated with anxiety symptoms. These findings suggest that promoting self-esteem and happiness while reducing burnout may be beneficial in preventing and managing anxiety symptoms among hospital nurses.

Factors Affecting Nurses’ Performance of Noise Management in Adult Intensive Care Units

The aim of this study was to identify factors affecting the noise management performance of adult intensive care unit (ICU) nurses in Korea. The ICU environment is exposed to various types of noises due to the use of medical devices for the treatment of critically ill patients. The noise has an adverse effect on nurses’ health and their nursing performance, which might potentially threaten patient safety. A cross-sectional study was conducted with a total of 148 nurses working in adult ICUs from two university hospitals in Korea. Data were collected using self-administered questionnaires, which included various aspects such as noise knowledge, response to noise, patient safety culture, and noise management performance. Multiple regression analysis revealed that teamwork (β = 0.33, p=0.004), patient safety policy, and procedure (β = 0.25, p=0.037), which were subscales of patient safety culture, as well as frequency of noise experience (β = 0.16, p=0.030) were significant factors affecting adult ICU nurses’ performance of noise management. This study provides a significant basis for promoting adult ICU nurses’ performance in noise management. A structured policy and procedure for noise management should be established for reducing noise in adult ICUs. In terms of nursing education, it is necessary to consider and develop team-based training programs to promote noise management performance in the ICU. Nurse managers and nursing organizations should consider how to create conditions in which nurses can recognize the importance of noise reduction and perform well in noise management.

Incidence rate and risk factors for post-intensive care syndrome subtypes among critical care survivors three months after discharge: A prospective cohort study

ObjectivesTo investigate the incidence of post-intensive care syndrome subtypes and their risk factors among intensive care unit survivors. Research methodology/designThis prospective observational cohort study assessed post-intensive care syndrome at three months after discharge in 475 survivors (median age of 62 years, 59.4 % male) admitted for more than 24 hours to 19 intensive care units. Setting19 intensive care units at four university hospitals in Korea. Main outcome measuresThree months after discharge, the Hospital Anxiety and Depression Scale, Posttraumatic Diagnosis Scale, Montreal Cognitive Assessment, and Activities of Daily Living were used to evaluate post-intensive care syndrome. ResultsParticipants exhibited eight subtypes of post-intensive care syndrome: post-intensive care syndrome free (50.3 %), impaired in physical (3.4 %), mental (13.5 %), cognitive (12.4 %), physical and mental (7.8 %), physical and cognitive (2.3 %), mental and cognitive (4.0 %) and all three domains (6.3 %). Age, unemployment, education, comorbidities, unplanned admission, longer stay, and place of discharge were risk factors for each domain. Age ≥ 65 years (OR 9.234, p < .001), female gender (OR = 5.143, p = .002), two or more comorbidities (OR = 8.701, p = .002), and discharge to an extended care facility (OR = 36.040, p < .001) were associated with increased probability of impairment in all three domains. ConclusionThe type with impaired in both mental and physical domains was the most prevalent in cases of co-occurrence. Discharge to an extended care facility was one of the most significant risk factor for the occurrence of each domain and intensity of post-intensive care syndrome. Implications for clinical practiceNurses must promote prevention strategies by proactively evaluating intensive care unit survivors for post-intensive care syndrome risk factors. Additionally, it is necessary to raise healthcare providers' awareness of post-intensive care syndrome evaluation and management in extended care facilities.

Factors influencing the supportive care needs of female patients with genital cancer in South Korea.

Genital cancers are particularly important compared to other cancers because of the psychological impact they have on the individual. This study investigated the complexity in illness and quality of life among female genital cancer patients and determined the effects of these factors on supportive care needs to provide evidential data for the development of nursing intervention strategies to reduce supportive care needs in female genital cancer patients. This cross-sectional study collected data from July 22 to August 17, 2021. The study subjects were 103 female outpatients and inpatients aged 19 years or older who were treated for cervical cancer, endometrial cancer, ovarian cancer, or other female genital cancers such as vulvar cancer and vaginal cancer in a university hospital in Korea. The data were analyzed with t-tests and Scheffé's test using SPSS 26.0. The factors affecting supportive care needs were examined using hierarchical regression. The average age of the subjects was 56.41 (±9.91) years. Cervical cancer was the most common diagnosis at 42.7%, followed by ovarian cancer at 34.0%, and endometrial cancer at 21.4%. The factors affecting supportive care needs included a middle school education or below (β = 0.21, P = .028), unemployment (β = 0.23, P = .018), complexity in illness (β = 0.32, P < .001), and quality of life (β = -0.68, P < .001). Developing a strategy for managing the complexity in illness and quality of life caused by various variables including disease stage and type of treatment is necessary to reduce the supportive care needs of female genital cancer patients. Improving their quality of life through effective communication with healthcare providers is essential.

ISSUES OF LIFE-SUSTAINING TREATMENT DECISION ACT IN CLINICAL PRACTICE FOR INDIVIDUALS AT THE END OF LIFE

Abstract This study aimed to investigate the status and issues related to the patient’s decision-making regarding life-sustaining treatment (LST) in clinical practice and to provide strategic suggestions to improve the hospital policy. The retrospective observational study was conducted with adult patients, admitted between Jan 1 and Dec 31, 2021, who went through the end-of-life process and died in a university hospital in Korea. The electronic data included age, gender, admission date, expiration date, and Do-not-attempt-resuscitation (DNAR) and LST-related data (date to sign, who signed, and clinical state when signed). A total of 916 patients were included. Only 4.1% of the patients decided on LST by themselves, while the decision was made mainly by the family, specifically children (54.2%). The time of signing DNAR consent was before eight days from the date of death (33.7%) and the previous day of the death (27.6%). While early warning score was used to predict the critical state of the patients, the period from the date of sign to the date of death was 8.9 (SD=25.7) days for DNAR and 2.76 (SD=6.95) days for LST. Strategic suggestions were made to facilitate the timing of signing the consent form for LST based on the early warning score, and encourage patient involvement in the decision-making process. Further efforts are required to improve the awareness of patients and medical staff on the implementation of LST and to clarify the ambiguity of the timing of document preparation.
