Effects of Standardized Patient Simulation and Mobile Applications on Nursing Students' Clinical Competence, Self-Efficacy, and Cultural Competence: A Quasi-Experimental Study.

BACKGROUND: Simulation-based education has emerged as an effective approach in nursing education worldwide. We aimed to evaluate the effectiveness of a surgical nursing education program based on a simulation using standardized patients and mobile applications among nursing students. METHODS: A mixed-methods design with a quasi-experimental longitudinal approach and focus group interviews was employed. The data were collected from 130 third-year nursing students at three different time points who were equally divided into experimental and control groups. This study measured the level of clinical surgical nursing competence, self-efficacy in clinical performance, cultural competence, and satisfaction with simulation experience. Four focus group interviews were conducted using open-ended questions to explore the participants' perspectives on the course's efficacy and satisfaction. RESULTS: There were statistically significant differences in clinical surgical nursing competence (F = 8.68, p < 0.001), self-efficacy in clinical performance (F = 13.56, p < 0.001), and cultural competence (F = 10.35, p < 0.001) across time between the intervention and control groups. Student satisfaction with the simulation-based training was high, particularly regarding debriefing and reflection, with an overall mean satisfaction level of 4.25 (0.40). Students' perspectives regarding integrated hybrid training are categorized into three themes: educational achievement, dynamic learning experiences, and satisfaction and suggestion. CONCLUSION: Simulation-based learning provides a dynamic and immersive educational experience that enables undergraduate nursing students to develop and refine essential clinical skills while also fostering confidence and cultural competence.

Therapeutic hypothermia after perinatal asphyxia in Vietnam: medium-term outcomes at 18 months - a prospective cohort study.

AIM: To determine neurodevelopmental outcome at 18 months after therapeutic hypothermia for hypoxic-ischaemic encephalopathy (HIE) infants in Vietnam, a low-middle-income country. METHOD: Prospective cohort study investigating outcomes at 18 months in severely asphyxiated outborn infants who underwent therapeutic hypothermia for HIE in Hanoi, Vietnam, during the time period 2016-2019. Survivors were examined at discharge and at 6 and 18 months by a neonatologist, a neurologist and a rehabilitation physician, who were blinded to the infants' clinical severity during hospitalisation using two assessment tools: the Ages and Stages Questionnaire (ASQ) and the Hammersmith Infant Neurological Examination (HINE), to detect impairments and promote early interventions for those who require it. RESULTS: In total, 130 neonates, 85 (65%) with moderate and 45 (35%) with severe HIE, underwent therapeutic hypothermia treatment using phase change material. Forty-three infants (33%) died during hospitalisation and in infancy. Among the 87 survivors, 69 (79%) completed follow-up until 18 months. Nineteen children developed cerebral palsy (8 diplegia, 3 hemiplegia, 8 dyskinetic), and 11 had delayed neurodevelopment. At each time point, infants with a normal or delayed neurodevelopment had significantly higher ASQ and HINE scores (p<0.05) than those with cerebral palsy. CONCLUSION: The rates of mortality and adverse neurodevelopment rate were high and comparable to recently published data from other low-middle-income settings. The ASQ and HINE were useful tools for screening and evaluation of neurodevelopment and neurological function.

A fatal eosinophilic granulomatosis with polyangiitis case presenting intracerebral hemorrhage and thrombocytopenia.

We report the case of a patient with eosinophilic granulomatosis with polyangiitis and unexplained thrombocytopenia that culminated in a fatal intracerebral hemorrhage. Because vessel damage associated with thrombocytopenia could be the leading cause of fatal hemorrhage, more urgent treatment of thrombocytopenia should be performed in such cases.

Challenges and Lessons Learned in the Development of a Participatory Learning and Action Intervention to Tackle Antibiotic Resistance: Experiences From Northern Vietnam.

Antibiotic use in the community for humans and animals is high in Vietnam, driven by easy access to over-the counter medicines and poor understanding of the role of antibiotics. This has contributed to antibiotic resistance levels that are amongst the highest in the world. To address this problem, we developed a participatory learning and action (PLA) intervention. Here we describe challenges and lessons learned while developing and testing this intervention in preparation for a large-scale One Health trial in northern Vietnam. We tested the PLA approach using community-led photography, and then reflected on how this approach worked in practice. We reviewed and discussed implementation documentation and developed and refined themes. Five main themes were identified related to challenges and lessons learned: understanding the local context, stakeholder relationship development, participant recruitment, building trust and motivation, and engagement with the topic of antibiotics and antimicrobial resistance (AMR). Partnerships with national and local authorities provided an important foundation for building relationships with communities, and enhanced visibility and credibility of activities. Partnership development required managing relationships, clarifying roles, and accommodating different management styles. When recruiting participants, we had to balance preferences for top-down and bottom-up approaches. Building trust and motivation took time and was challenged by limited study team presence in the community. Open discussions around expectations and appropriate incentives were re-visited throughout the process. Financial incentives provided initial motivation to participate, while less tangible benefits like collective knowledge, social connections, desire to help the community, and new skills, sustained longer-term motivation. Lack of awareness and perceived importance of the problem of AMR, affected initial motivation. Developing mutual understanding through use of common and simplified language helped when discussing the complexities of this topic. A sense of ownership emerged as the study progressed and participants understood more about AMR, how it related to their own concerns, and incorporated their own ideas into activities. PLA can be a powerful way of stimulating community action and bringing people together to tackle a common problem. Understanding the nuances of local power structures, and allowing time for stakeholder relationship development and consensus-building are important considerations when designing engagement projects.

Is T2 mapping reliable in evaluation of native and repair cartilage tissue of the knee?

PURPOSE: To evaluate the effect of imaging plane and experience of observers on the reliability of T2 mapping of native and repair cartilage tissue of the knee. METHODS: Fifteen consecutive patients from two randomised controlled trials (RCTs) were included in this cross-sectional study. Patients with an isolated knee cartilage lesion were randomised to receive either debridement or microfracture (RCT 1) or debridement or autologous chondrocyte implantation (RCT 2). T2 mapping was performed in coronal and sagittal planes two years postoperatively. A musculoskeletal radiologist, a resident of radiology and two orthopaedic surgeons measured the T2 values independently. Intraclass Correlation Coefficient (ICC) with 95% Confidence Intervals was used to calculate the inter- and intraobserver agreement. RESULTS: Mean age for the patients was 36.8 ± 11 years, 8 (53%) were men. The overall interobserver agreement varied from poor to good with ICCs in the range of 0.27- 0.76 for native cartilage and 0.00 - 0.90 for repair tissue. The lowest agreement was achieved for evaluations of repair cartilage tissue. The estimated ICCs suggested higher inter- and intraobserver agreement for radiologists. On medial femoral condyles, T2 values were higher for native cartilage on coronal images (p < 0.001) and for repair tissue on sagittal images (p < 0.001). CONCLUSIONS: The reliability of T2 mapping of articular cartilage is influenced by the imaging plane and the experience of the observers. This influence may be more profound for repair cartilage tissue. This is important to consider when using T2 mapping to measure outcomes after cartilage repair surgery. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02637505 and NCT02636881 , registered December 2015. LEVEL OF EVIDENCE: II, based on prospective data from two RCTs.

Distribution of Serological Response to Burkholderia pseudomallei in Swine from Three Provinces of Vietnam.

(1) Background: Burkholderia pseudomallei is an environmentally mediated saprophytic pathogen that can cause severe disease in humans. It is well known that B. pseudomallei survives in tropical moist soil environments worldwide, but melioidosis is gaining recognition as a public and veterinary health issue in Vietnam. The contribution of animals to human disease is unknown, necessitating further investigation. (2) Methods: Swine sera were collected from two populations, one grazing and one commercially farmed, from three provinces in Vietnam. ELISAs utilizing B. pseudomallei capsular polysaccharide (CPS), outer polysaccharide (OPS), and Hcp1 protein were used to screen serum samples. Positive samples were mapped to the commune level. Seroprevalence calculations and pig population estimates were used to approximate number of swine exposures per commune. (3) Results: Grazing pigs from Hoa Binh had significantly higher seropositivity levels (11.4%, 95% CI: 9.7-13.1) compared to farmed pigs from Ha Tinh and Nghe An (4%, 95% CI: 3.3-4.7). Average swine seropositivity rates were ~6.3% (95% CI: 5-7.9), higher than previously identified in Vietnam (~0.88%). (4) Conclusions: Initial serological sampling identified a significant number of seropositive and potential melioidosis infections occurring in swine in Vietnam. This work is a critical step in understanding the role swine may play in the epidemiology of human melioidosis in Vietnam.

Sustained effects of a multimodal campaign aiming at hand hygiene improvement on compliance and healthcare-associated infections in a large gynaecology/obstetrics tertiary-care centre in Vietnam.

BACKGROUND: Hung Vuong Hospital (HVH) is a 900-bed maternity hospital in Ho-Chi-Minh-City, Vietnam. Due to low compliance, a quasi-experimental, observational study was conducted with the aim to improve hand hygiene. METHODS: A multimodal promotion strategy was established in 2010 and further developed towards ongoing, repetitive and inventive campaigns including patient participation. Hand hygiene compliance was monitored by direct observation and healthcare-associated infections (HAIs) by applying standard definitions. RESULTS: Between 2010 and 2018, a total of 43,711 hand hygiene opportunities were observed. Compliance improved from 21.5% (95%CI: 20.2-22.8%) in 2010 to 75.1% (73.9-76.2%) in 2018 (incidence rate ratio, IRR , 1.10; 95%CI, 1.10-1.11). This was achieved through increasing recourse to alcohol-based hand rubbing. A total of 554,720 women were admitted to HVH during the study period for 353,919 deliveries (198,679 vaginal; 155,240 by C-section) and 257,127 surgical procedures. The HAI-incidence decreased significantly from 1.10 episodes per 1000 patient-days in 2010 to 0.45 per 1000 patient-days in 2018 (IRR 0.85; 95%CI, 0.79-0.90). Significant improvement was observed also for surgical site infections after gynaecological surgery (IRR 0.95; 95%CI, 0.92-0.99) and endometritis after abortion (IRR 0.80; 95%CI, 0.68-0.93). CONCLUSIONS: A multimodal strategy aiming at behaviour change significantly improved and sustained hand hygiene, which contributed to the reduction of healthcare-associated infections.

Enhanced infection control interventions reduced catheter-related bloodstream infections in the neonatal department of Hung Vuong Hospital, Vietnam, 2011-2012: a pre- and post-intervention study.

Background: Catheter-related bloodstream infections (CR-BSI) cause high neonatal mortality and are related to inadequate aseptic technique during the care and maintenance of a catheter. The incidence of CR-BSI among neonates in Hung Vuong Hospital was higher than that of other neonatal care centres in Vietnam. Methods: An 18-month pre- and post-intervention study was conducted over three 6-month periods to evaluate the effectiveness of the intervention for CR-BSI and to identify risk factors associated with CR-BSI. During the intervention period, we trained all nurses in the Department of Neonatology on BSI preventive practices, provided auditing and feedback about aseptic technique during catheter care and maintenance, and reorganised preparation of total parenteral nutrition. All neonates with intravenous catheter insertion ≥48 h in the pre- and post-intervention period were enrolled. A standardised questionnaire was used to collect data. Blood samples were collected for cultures. We used Poisson regression to calculate rate ratio (RR) and 95% confidence interval (CI) for CR-BSI incidence rates and logistic regression to identify risk factors associated with CR-BSI. Results: Of 2225 neonates enrolled, 1027 were enrolled in the pre-intervention period, of which 53 CR-BSI cases occurred in 8399 catheter-days, and 1198 were enrolled in the post-intervention period, of which 32 CR-BSI cases occurred in 8324 catheter-days. Incidence rates of CR-BSI significantly decreased after the intervention (RR = 0.61, 95% CI 0.39-0.94). Days of hospitalisation, episodes of non-catheter-related hospital-acquired infections, and the proportion of deaths significantly decreased after the intervention (p < 0.01). The CR-BSI was associated with days of intravenous catheter (odds ratio [OR] = 1.05, 95% CI 1.03-1.08), use of endotracheal intubation (OR = 2.27, 95% CI 1.27-4.06), and intravenous injection (OR = 8.50, 95% CI 1.14-63.4). Conclusions: The interventions significantly decreased the incidence rate of CR-BSI. Regular refresher training and auditing and feedback about aseptic technique during care and maintenance of catheters are critical to reducing CR-BSI.

An educational intervention to improve hand hygiene compliance in Vietnam.

BACKGROUND: Hand hygiene compliance is the basis of infection control programs. In developing countries models to improve hand hygiene compliance to reduce healthcare acquired infections are required. The aim of this study was to determine hand hygiene compliance following an educational program in an obstetric and gynecological hospital in Vietnam. METHODS: Health care workers from neonatal intensive care, delivery suite and a surgical ward from Hung Vuong Hospital, Ho Chi Minh City, Vietnam undertook a 4-h educational program targeting hand hygiene. Compliance was monitored monthly for six months following the intervention. Hand hygiene knowledge was assessed at baseline and after six months of the study. RESULTS: There were 7124 opportunities over 370 hand hygiene recording sessions with 1531 opportunities at baseline and 1620 at 6 months following the intervention. Hand hygiene compliance increased significantly from baseline across all sites (43.6% [95% Confidence interval CI: 41.1-46.1] to 63% [95% CI: 60.6-65.3]; p < 0.0001). Health care worker hand hygiene compliance increased significantly after intervention (p < 0.0001). There were significant improvements in knowledge scores from baseline to 2 months post educational intervention with mean difference standard deviations (SD): 1.5 (2.5); p < 0.001). CONCLUSIONS: A simple educational model was implemented in a Vietnamese hospital that revealed good hand hygiene compliance for an extended period of time. Hand hygiene knowledge increased during the intervention. This hand hygiene model could be used in developing countries were resources are limited.

Development of photoreactive degradable branched polyesters with high thermal and mechanical properties.

Branched polyesters composed of poly(L-lactide)s (PLLAs) and 3,4-dihydroxycinnamic acid (DHCA) were obtained by the thermal melt-polycondensation of 3,4-diacetoxycinnamic acid (DACA)-terminally conjugated PLLAs (DACA-PLLAs). The chemical structures of the DHCA/PLLA polyesters were confirmed by FT-IR and (1)H NMR measurements. All of the polyesters showed high photoreactivities independent of LLA content. Furthermore, the polyesters had high solubility even after UV irradiation. Interestingly, the thermal stability and mechanical properties of PLLA were improved depending on the incorporation ratio of the DHCA moiety into the backbone. The hydrolysis speed of the DHCA/PLLA polyesters decreased upon increasing the composition of LLA, but the pure PLLA presented the highest hydrolysis speed. Furthermore, all of the polyesters showed faster hydrolysis after UV irradiation as compared to the uncross-linked samples. These novel branched DHCA/PLLA polyesters with high thermal stabilities, mechanical properties and photocontrollable degradability may be useful as functional degradable polyester for the environmental and biomedical fields.
