The longitudinal effect of concept map teaching on critical thinking of nursing students.

Concept map is a useful cognitive tool for enhancing a student's critical thinking by encouraging students to process information deeply for understanding. However, there is limited understanding of longitudinal effects of concept map teaching on students' critical thinking. The purpose of the study was to investigate the growth and the other factors influencing the development of critical thinking in response to concept map as an interventional strategy for nursing students in a two-year registered nurse baccalaureate program. The study was a quasi-experimental and longitudinal follow-up design. A convenience sample was drawn from a university in central Taiwan. Data were collected at different time points at the beginning of each semester using structured questionnaires including Critical Thinking Scale and Approaches to Learning and Studying. The intervention of concept map teaching was given at the second semester in the Medical-Surgical Nursing course. The results of the findings revealed student started with a mean critical thinking score of 41.32 and decreased at a rate of 0.42 over time, although not significant. After controlling for individual characteristics, the final model revealed that the experimental group gained a higher critical thinking score across time than the control group. The best predictive variables of initial status in critical thinking were without clinical experience and a higher pre-test score. The growth in critical thinking was predicted best by a lower pre-test score, and lower scores on surface approach and organized study. Our study suggested that concept map is a useful teaching strategy to enhance student critical thinking.

Predictors and patterns of chronic pain three months after cardiac surgery in Taiwan.

OBJECTIVES: Clinicians and researchers have a very limited understanding of how acute pain after cardiac surgery may develop into chronic pain. The aims of this study were to describe the pattern of pain during the first 3 months after cardiac surgery and to examine the predictors of surgery-related chronic pain. DESIGN: A prospective panel study was conducted to monitor changes in worst and average pain intensity before and during the first 3 months following cardiac surgery in a sample of Taiwanese patients. Fifty-three patients who underwent a midsternotomy rated pain intensity before surgery and at postoperative days 7, 10, 30, and 90. The participants also rated beliefs about opioid use, and their medical records were reviewed to document opioid use during the first week after surgery. RESULTS: The patients who reported chronic pain 90 days following surgery showed an unusual pattern of an increase in pain from 10 to 30 days after surgery. Higher worst pain intensity ratings at 30 days following surgery and more negative beliefs in opioid use were both associated with a greater likelihood of reporting chronic pain at 3 months. CONCLUSION: Patients reporting a pattern of increasing pain starting about 10 days after surgery and holding negative beliefs about opioid use are at risk of developing chronic pain and may require more careful monitoring and pain treatment. The possible benefits of interventions that minimize pain during the weeks after surgery and that alter negative beliefs about opioid use should be examined in future research.
