RESUMO
BACKGROUND: Patients may be endangered if new graduate nurses cannot recognize and manage anaphylactic shock. Consequently, enhancing the new graduate nurses' understanding of their roles and responsibilities during the rescue of a patient with anaphylactic shock is important. However, due to its inherent limitations, traditional classroom-based teaching makes it difficult to explore the potential of the students. Although popular simulation teaching has several notable advantages, it has not been proven to be effective in training inexperienced nurses on anaphylactic shock. We investigated the effect of a standardized patient-based simulation on the behaviors of new graduate nurses' during anaphylactic shock rescue to identify an effective and safe method for contemporary nursing education. METHODS: Except for the ill or pregnant, all the new graduate nurses were included in the study as students to undergo a standardized patient-based simulation conducted in the clinical skills center of a general hospital. The simulation training was designed to teach students to recognize the signs and symptoms of anaphylactic shock, place the patient in the correct position, stop the ongoing intravenous infusion of the antibiotic which triggers the anaphylactic shock, restart an intravenous infusion on a new infusion apparatus, give 100% oxygen via a nasal cannula or mask, preserve airway patency, call the rapid response team, and correctly administer the medications prescribed by the clinicians. Before and after the training, the instructors evaluated each student's skills and behaviors using a clinical competency evaluation list. After the training, all students completed the Chinese version of the Simulation Design Scale (SDS) to demonstrate their satisfaction with the program and then participated in semi-structured interviews with their instructors. RESULTS: All 104 graduate nurses had a significant improvement on the 6 competencies of the clinical competency evaluation list after the simulation training (P < 0.001). The SDS scores revealed that the students were highly satisfied with all the aspects of the simulation training (the 20 satisfaction rates were all above 90.00%). During the semi-structured interviews, most of the new graduate nurses reported that simulation training in the management of anaphylactic shock was critical and would guide them in clinical practice. CONCLUSION: Simulation training in anaphylactic shock is a potentially viable and effective method for teaching new graduate nurses to manage clinical incidents.
RESUMO
Resumo Objetivo Avaliar os efeitos da intervenção terapêutica de enfermagem baseada no modelo de trajetória da doença crônica na ansiedade e na qualidade de vida de pacientes com doença cardíaca coronária (DCC). Métodos Um total de 118 pacientes com DCC admitidos entre fevereiro de 2019 e fevereiro de 2021 foram distribuídos aleatoriamente em grupos controle e observação (n = 59). O grupo controle recebeu intervenção de enfermagem de rotina, enquanto o grupo observação recebeu intervenção com base no modelo de trajetória da doença crônica. Os sintomas clínicos, a escala de autoavaliação de ansiedade (SAS), a qualidade de vida (QV) e as pontuações de autoeficácia foram comparados. As taxas de incidência de complicações foram comparadas. A análise de regressão linear multivariada foi realizada para o efeito mediador da autoeficácia na relação entre ansiedade e QV. Um modelo de equação estrutural foi construído e validado. Resultados Após a intervenção, os sintomas clínicos e a pontuação da SAS diminuíram significativamente em ambos os grupos, especialmente no grupo observação (P<0,05). As pontuações de QV e autoeficácia aumentaram significativamente em ambos os grupos, particularmente no grupo de observação (P<0,05). A pontuação de autoeficácia correlacionou-se negativamente com a pontuação SAS e positivamente com a pontuação QV. Houve correlação negativa entre a pontuação SAS e a pontuação QV (P<0,05). O modelo de autoeficácia, ansiedade e QV apresentou boa adequação, e o efeito mediador da autoeficácia na relação entre ansiedade e QV foi de 0,896. A taxa de incidência de complicações foi significativamente menor no grupo observação do que no grupo controle (P <0,05). Conclusão A intervenção de enfermagem baseada no modelo de trajetória da doença crônica alivia significativamente a ansiedade, melhora a QV e aumenta a pontuação de autoeficácia de pacientes com DCC. A autoeficácia é um mediador da relação entre ansiedade e QV.
Resumen Objetivo Evaluar los efectos de la intervención terapéutica de enfermería con base en el modelo de trayectoria de la enfermedad crónica en la ansiedad y en la calidad de vida de pacientes con enfermedad arterial coronaria (EAC). Métodos Un total de 118 pacientes con EAC admitidos entre febrero de 2019 y febrero de 2021 fueron distribuidos aleatoriamente en grupos control y observación (n = 59). El grupo control recibió intervención de enfermería de rutina, mientras el grupo observación recibió intervención con base en el modelo de trayectoria de la enfermedad crónica. Se compararon los síntomas clínicos, la escala de autoevaluación de ansiedad (EAA), la calidad de vida (CV) y el puntaje de autoeficacia. Se compararon las tasas de incidencia de complicaciones. El análisis de regresión lineal multivariado se realizó para el efecto mediador de la autoeficacia en la relación entre ansiedad y CV. Se elaboró y validó un modelo de ecuación estructural. Resultados Después de la intervención, los síntomas clínicos y el puntuaje de la EAA disminuyeron de forma considerable en ambos grupos, especialmente en el grupo observación (P<0,05). Los puntajes de CV y de autoeficacia aumentaron considerablemente en ambos grupos, particularmente en el grupo de observación (P<0,05). El puntaje de autoeficacia se correlacionó negativamente con el puntaje EAA y positivamente con el puntaje CV. Hubo una correlación negativa entre el puntaje EAA y el puntaje CV (P<0,05). El modelo de autoeficacia, ansiedad y CV presentó una buena adecuación y el efecto mediador de la autoeficacia en la relación entre ansiedad y CV fue de 0,896. La tasa de incidencia de complicaciones fue considerablemente inferior en el grupo observación que en el grupo control (P <0,05). Conclusión La intervención de enfermería con base en el modelo de trayectoria de la enfermedad crónica alivia de forma considerable la ansiedad, mejora la CV y aumenta el puntaje de autoeficacia de pacientes con EAC. La autoeficacia es un mediador de la relación entre ansiedad y CV.
Abstract Objective We aimed to assess the effects of nursing intervention therapy based on chronic disease trajectory model on anxiety and quality of life (QOL) of patients with coronary heart disease (CHD). Methods A total of 118 CHD patients admitted from February 2019 to February 2021 were randomly assigned into control and observation groups (n=59). Control group was given routine nursing intervention, while observation group was given intervention based on chronic disease trajectory model. Clinical symptom, self-rating anxiety scale (SAS), QOL and self-efficacy scores were compared. Incidence rates of complications were compared. Multivariate linear regression analysis was performed for the mediating effect of self-efficacy on relationship between anxiety and QOL. A structural equation model was constructed and verified. Results After intervention, clinical symptom and SAS scores significantly declined in both groups, especially in observation group (P<0.05). QOL and self-efficacy scores rose significantly in both groups, particularly in observation group (P<0.05). Self-efficacy score was negatively correlated with SAS score and positively correlated with QOL score, and there was a negative correlation between SAS score and QOL score (P<0.05). The model of self-efficacy, anxiety and QOL had good fitness, and the mediating effect of self-efficacy on relationship between anxiety and QOL was 0.896. The incidence rate of complications was significantly lower in observation group than in control group (P<0.05). Conclusion Nursing intervention based on chronic disease trajectory model significantly relieves the anxiety, improves QOL, and increases the self-efficacy score of CHD patients. Self-efficacy is a mediator for the relationship between anxiety and QOL.
