Effectiveness of a Game-Based Mobile App for Educating Intensive Critical Care Specialist Nurses in Extracorporeal Membrane Oxygenation Pipeline Preflushing: Quasi-Experimental Trial.

Background: In the context of training specialist nurses and nursing education, a game-based mobile app was used as a simulation to teach intensive critical care specialist nurses the knowledge and skills of extracorporeal membrane oxygenation (ECMO) pipeline preflushing. Objective: This study aimed to evaluate the impact of a game-based mobile app on improving ECMO pipeline preflushing skills in intensive critical care specialist nurses. Methods: A total of 86 intensive critical care specialist nurses who were learning ECMO for the first time were included in this study. The nurses were divided into 2 groups: a control group (n=43) and an experimental group (n=43). Participants in the experimental group used a game-based mobile app for simulation exercises; the control group received no additional intervention. All participants took a theoretical test and a skill operation test at the beginning of the study and 1 week later. The differences in scores between the 2 groups were compared, and the learning curve of the experimental group was observed. Results: The final theoretical test scores (88.44 and 85.02) and skill operation test scores (89.42 and 86.33) of the experimental group and control group, respectively, were significantly higher than those of the initial tests (theoretical test scores: 75.88 and 74.42; skill operation test scores: 75.44 and 75.93; all P<.001). The scores of the final theoretical test (88.44) and the final skill operation test (89.42) in the experimental group were higher than the scores of the control group (85.02; P<.001 and 86.33; P<.001, respectively). Learning curve analysis showed that the experimental group needed an average of 17 operations to master the skill. Conclusions: This study suggests that a game-based mobile app may be more effective for intensive critical care specialist nurses in ECMO pipeline preflushing education than traditional Chinese lecture-practice education.

Research progress related to thermosensitive hydrogel dressings in wound healing: a review.

Wound healing is a dynamic and complex process in which the microenvironment at the wound site plays an important role. As a common material for wound healing, dressings accelerate wound healing and prevent external wound infections. Hydrogels have become a hot topic in wound-dressing research because of their high water content, good biocompatibility, and adjustable physical and chemical properties. Intelligent hydrogel dressings have attracted considerable attention because of their excellent environmental responsiveness. As smart polymer hydrogels, thermosensitive hydrogels can respond to small temperature changes in the environment, and their special properties make them superior to other hydrogels. This review mainly focuses on the research progress in thermosensitive intelligent hydrogel dressings for wound healing. Polymers suitable for hydrogel formation and the appropriate molecular design of the hydrogel network to achieve thermosensitive hydrogel properties are discussed, followed by the application of thermosensitive hydrogels as wound dressings. We also discuss the future perspectives of thermosensitive hydrogels as wound dressings and provide systematic theoretical support for wound healing.

Effectiveness of a Game-Based Mobile Application in Educating Nursing Students on Venous Blood Specimen Collection: A Randomized Controlled Trial.

Aim: Incorporating mobile applications into traditional clinical teaching methods to assess the impact of game-based mobile applications on the practical knowledge and skill levels of venous blood specimen collection among nursing students. Background: Although game-based mobile applications are recognized as teaching aids that replicate clinical practice in a safe environment, their impact and effectiveness are relatively unknown in the education of nursing students. Design: In September 2021, a single-blind randomized controlled trial was conducted in a university-affiliated hospital in China. Methods: One hundred five nursing students were randomly divided into the control group (n = 53) and the experimental group (n = 52). All participants received the same theoretical and operational training. For the next 7 days, the experimental group used a game-based mobile application, and the control group practiced venous blood specimen collection using traditional teaching methods. We observed the before-and-after comparison of the skill performance and learning curve of both groups of participants. Results: The final skill performance scores of the nursing students in the experimental group were higher than that of the nursing students in the control group (P < 0.001). Analysis of the learning curve showed that to master the skills, the experimental and control groups needed an average of 8 and 10 repetitions, respectively. Conclusion: This mobile application has a positive learning effect on nursing students' venous blood specimen collection skills in the short term. It should be applied to the training of clinical nursing skills.

Effectiveness of a Game-Based Phone Application in Educating Health Care Workers on the Proper Use of Personal Protective Equipment.

Objective This study explored the feasibility and effects of a game-based phone application for training health care workers to use personal protective equipment. Method A single-blind randomized controlled trial was conducted. All participants in the experimental group (n = 123) and the control group (n = 125) received 75 minutes of training and were provided with a video and a paper copy of the procedures. Participants in the experimental group used an additional game-based phone application to simulate the procedures. Results Participants in the experimental group practiced a median of 15 times (range, 14-19 times). The learning curve indicated that they needed at least 12 repetitions to master the skill. Score improvements (Z = -2.257, p = .024) in the experimental group were significantly superior to those in the control group, as were the incidences of procedural errors of hand hygiene (χ2 = 4.085, p = .043) and protective clothing (χ2 = 5.394, p = .02). Conclusion The game-based phone application simulation guided participants to practice enough times to master the skill, enhance their skill performance, and reduce the incidence of procedural errors.

Establishment of a nomogram model for predicting adverse outcomes in advanced-age pregnant women with preterm preeclampsia.

AIM: To establish a model for predicting adverse outcomes in advanced-age pregnant women with preterm preeclampsia in China. METHODS: We retrospectively collected the medical records of 896 pregnant women with preterm preeclampsia who were older than 35 years and delivered at the Affiliated Hospital of Qingdao University from June 2018 to December 2020. The pregnant women were divided into an adverse outcome group and a non-adverse outcome group according to the occurrence of adverse outcomes. The data were divided into a training set and a verification set at a ratio of 8:2. A nomogram model was developed according to a binary logistic regression model created to predict the adverse outcomes in advanced-age pregnant women with preterm preeclampsia. ROC curves and their AUCs were used to evaluate the predictive ability of the model. The model was internally verified by using 1000 bootstrap samples, and a calibration diagram was drawn. RESULTS: Binary logistic regression analysis showed that platelet count (PLT), uric acid (UA), blood urea nitrogen (BUN), prothrombin time (PT), and lactate dehydrogenase (LDH) were the factors that independently influenced adverse outcomes (P < 0.05). The AUCs of the internal and external verification of the model were 0.788 (95% CI: 0.737 ~ 0.764) and 0.742 (95% CI: 0.565 ~ 0.847), respectively. The calibration curve was close to the diagonal. CONCLUSIONS: The model we constructed can accurately predict the risk of adverse outcomes of pregnant women of advanced age with preterm preeclampsia, providing corresponding guidance and serving as a basis for preventing adverse outcomes and improving clinical treatment and maternal and infant prognosis.

Sedentary behaviors and gestational diabetes mellitus: A systematic review.

AIM: Sedentary behaviors are activities that expend less energy than 1.5 metabolic equivalents, such as watching TV, sitting. We aim to systematically review the evidence to determine the association of sedentary behavior (SB) with the risk of gestational diabetes mellitus, and the associations of SB with health outcomes in pregnant women with gestational diabetes mellitus (GDM) and women at high risk of gestational diabetes mellitus. METHODS: Two researchers independently performed a literature search using PubMed, Medline, EMBASE, CINAHL, the Cochrane Library, the Rehabilitation and Sports Medicine Source, and the Sedentary Behavior Research Database for studies published up to January 27, 2021. Randomized controlled trials, quasi-experimental studies, and observational studies were screened and selected if SB was assessed in the context of gestational diabetes mellitus. Two reviewers extracted the relevant information and independently assessed the included studies for quality and bias. RESULTS: Eighteen studies were included, involving 60 804 patients, and the timeline of the original study included was from 2006 to 2021. Our review showed that SB before pregnancy was not associated with the risk of gestational diabetes mellitus, while SB during pregnancy was uncertain about the risk of gestational diabetes mellitus. In addition, there were significant associations between SB time and metabolic outcomes. In addition, SB may cause some adverse maternal and fetal outcomes. CONCLUSION: SB is likely to be the intermediary variable between occurrence of GDM and adverse maternal and infant outcome, rather than a direct influencing factor. Limited by the quantity and quality of included studies, the above conclusions need to be verified by more high-quality studies.

Effectiveness of a game-based mobile application in educating nursing students on flushing and locking venous catheters with pre-filled saline syringes: A randomized controlled trial.

AIM: This study aimed to determine the effect of a game-based mobile application on the skill levels of nursing students in respect of flushing and locking of venous catheters with pre-filled saline syringes. BACKGROUND: In the context of the education of nursing students, a game-based mobile application was used as a motivational aid to improve nursing students' skills in flushing and locking of venous catheters. DESIGN: A single-blind randomized controlled trial was conducted from August 2020, in a university-affiliated hospital in China. METHODS: A total of 154 nursing students were divided randomly into two groups: a control group (n = 77) and an experimental group (n = 77). All the participants received a 30-min theoretical interpretation, 30-min demonstration, and one opportunity to practice. For the next seven days, the participants in the experimental group used a game-based mobile application as a motivational aid to practice their skills in flushing and locking of venous catheters; the control group received no additional intervention. We observed the skill performance and the incidence of errors in the procedural steps of the participants in the two groups at first and seven days later, along with the learning curve of the skills of the experimental group in respect of flushing and locking of venous catheters. RESULTS: The final skill performance scores of the nursing students in the experimental group were higher than the average scores of the nursing students in the control group (p = 0.003); The incidence of errors in material preparation rate, hand hygiene, and flushing and locking in the experimental group were lower than that in the control group (p = 0.027, p = 0.035, p = 0.045). Analysis of the learning curve revealed that the experimental group needed an average of 11 repeat practices sessions to master the skills. CONCLUSIONS: In the short term, the game-based mobile application was effective in improving the skills of nursing students in flushing and locking venous catheters with pre-filled saline syringes. It is an effective complement to existing training methods.
