Objectives: Critical CHD is associated with morbidity and mortality, worsened by delayed diagnosis. Paediatric residents are front-line clinicians, yet identification of congenital CHD remains challenging. Current exposure to cardiology is limited in paediatric resident education. We evaluated the impact of rapid cycle deliberate practice simulation on paediatric residents’ skills, knowledge, and perceived competence to recognise and manage infants with congenital CHD. Methods: We conducted a 6-month pilot study. Interns rotating in paediatric cardiology completed a case scenario assessment during weeks 1 and 4 and participated in paired simulations (traditional debrief and rapid cycle deliberate practice) in weeks 2–4. We assessed interns’ skills during the simulation using a checklist of “cannot miss” tasks. In week 4, they completed a retrospective pre-post knowledge-based survey. We analysed the data using summary statistics and mixed effect linear regression. Results: A total of 26 interns participated. There was a significant increase in case scenario assessment scores between weeks 1 and 4 (4, interquartile range 3–6 versus 8, interquartile range 6–10; p-value < 0.0001). The percentage of “cannot miss” tasks on the simulation checklist increased from weeks 2 to 3 (73% versus 83%, p-value 0.0263) and from weeks 2–4 (73% versus 92%, p-value 0.0025). The retrospective pre-post survey scores also increased (1.67, interquartile range 1.33–2.17 versus 3.83, interquartile range 3.17–4; p-value < 0.0001). Conclusion: Rapid cycle deliberate practice simulations resulted in improved recognition and initiation of treatment of simulated infants with congenital CHD among paediatric interns. Future studies will include full implementation of the curriculum and knowledge retention work.

儿科住院医师心脏急症识别

目的：危重冠心病与发病率和死亡率相关，并因延迟诊断而恶化。儿科住院医生是一线临床医生，但先天性冠心病的识别仍然具有挑战性。目前，儿科住院医师教育中对心脏病学的了解有限。我们评估了快速循环刻意练习模拟对儿科住院医生识别和管理先天性先天性心脏病婴儿的技能、知识和感知能力的影响。方法：我们进行了为期 6 个月的试点研究。儿科心脏病学实习生在第 1 周和第 4 周完成病例情景评估，并在第 2 至第 4 周参加配对模拟（传统汇报和快速循环刻意练习）。我们在模拟过程中使用“不能错过”任务清单来评估实习生的技能。第四周，他们完成了一项回顾性岗前知识调查。我们使用汇总统计和混合效应线性回归分析数据。结果：共有26名实习生参与。第 1 周和第 4 周之间，病例情景评估分数显着增加（4，四分位距 3-6 与 8，四分位距 6-10；p 值 < 0.0001）。模拟清单上“不能错过”任务的百分比从第 2 周增加到第 3 周（73% 对比 83%，p 值 0.0263），从第 2 周到第 4 周（73% 对比 92%，p 值 0.0025）有所增加。回顾性前后调查得分也有所增加（1.67，四分位距 1.33-2.17 对比 3.83，四分位距 3.17-4；p 值 < 0.0001）。结论：快速循环刻意练习模拟提高了儿科实习生对患有先天性 CHD 的模拟婴儿的认识和开始治疗的能力。未来的研究将包括全面实施课程和知识保留工作。
