This Design and Development Research (DDR) study, utilizing a quasi-experimental one-group pretest-posttest design, aimed to develop and evaluate the effectiveness of a prototype pediatric central venous catheterization (CVC) circulation model on the practical nursing skills of nursing students. The model integrated design thinking concepts and Kolb’s (2015) experiential learning theory, developed in collaboration with electrical power engineering experts. The sample consisted of 30 fourth-year nursing students selected through purposive sampling. The research instruments included: 1) a prototype pediatric CVC circulation model focusing on anatomical realism and a pressurized tubing system, 2) an E-book practical manual, and 3) a practical nursing skill assessment form. The instruments were validated by experts (IOC = 0.67–1.00) with a reliability coefficient of 0.76. Data were analyzed using descriptive statistics and a paired t-test.
The results revealed that: 1) the developed innovation featured two models based on catheter insertion sites (internal jugular and subclavian veins) connected to a real catheter system for concrete flushing and locking practice; and 2) the post-test mean practical skill score (Mean = 34.73, S.D. = 1.61) was significantly higher than the pre-test score (Mean = 18.63, S.D. = 2.78) (t = 35.133, p < .001, 95% CI = [15.163, 17.037]). The dimension with the highest mean score increase was the aseptic technique. In conclusion, the innovative learning package significantly enhanced students' practical skills.
The findings suggest that nursing institutions integrate this innovative package into practicum courses to prepare and enhance procedural competencies among learners within a safe environment prior to clinical placement.
