ABSTRACT
INTRODUCTION: We assessed the effectiveness of a simulation-based education program to improve novice nurses' clinical judgment skills. METHODS: A simulation education program was implemented for 21 novice nurses. Surveys were conducted on program satisfaction, learning, and clinical judgment skills before, immediately after, and two months after the program. RESULTS: Novice nurses were highly satisfied with the simulation education program. The following nine categories were identified as learnings: provide psychological care for patients, conduct sufficient observation, conduct assessment and make judgment based on observational findings, consult and report appropriately to senior nurses, take response action calmly, collect necessary information, acquire knowledge, predict patients' conditions, and make environmental arrangements. The subscale score for theoretical and practical reasoning was significantly higher immediately after and two months after the program than before it. In addition, the subscale for grasping the condition by observation was significantly higher two months after the program than before and immediately after it. CONCLUSION: The novice nurses learned to sufficiently observe, obtain necessary information, and prospectively assess patients' conditions by taking part in the simulation education program. The subscale score for grasping the condition by observation was significantly higher two months after the program than before and immediately after it. After the simulation program, novice nurses were likely actively practicing nursing; therefore, this program may not be directly responsible for the improvement of these new nurses' clinical judgment. Nevertheless, we found that the completion of the simulation program was correlated with enhanced clinical judgment.
ABSTRACT
The aim of the present study was to examine the effects of endurance training on heart rate (HR) recovery after exercise and cardiac autonomic nervous system (ANS) modulation in female marathon runners by comparing with untrained controls. Six female marathon runners (M group) aged 32-40 years and eight age-matched untrained females (C group) performed a maximum-effort treadmill running exercise. Maximal oxygen uptake (VO2max) was measured during the exercise with a gas analyzer connected to subjects through a face mask. Heart rate, blood pressure and blood lactate were measured before and after the exercise. Rating of perceived exertion (RPE) to the exercise was obtained immediately after the exercise. Holter ECG was recorded and analyzed with power spectral analysis of heart rate variability (HRV) to investigate the cardiac ANS modulation. The M group had significantly higher VO2max, faster HR recovery after exercise, higher Mean RR, SDRR, HF power and lower LF/HF ratio at rest compared with the C group. The M group also presented greater percent decrease of blood pressure after exercise, although their blood pressure after exercise was higher than the C group. It is suggested that endurance training induced significant alterations in cardiac ANS modulation at rest and significant acceleration of HR recovery after exercise in female marathon runners. Faster HR recovery after exercise in the female marathon runners should result from their higher levels of HRV, higher aerobic capacity and exaggerated blood pressure response to exercise compared with untrained controls. Key PointsThe effects of endurance training on HR recovery after exercise and cardiac ANS modulation were investigated in female marathon runners by comparing with untrained controls.Time and frequency domain analysis of HRV was used to investigate cardiac ANS modulation.As compared with untrained controls, the female marathon runners showed faster HR recovery after exercise, which should result from their higher levels of HRV, higher aerobic capacity and exaggerated blood pressure response to exercise.
