目的 探讨护理警示标识对老年冠心病患者住院期间护理不良事件的预防作用。方法 选取在心内科住院的60岁及 以上的老年冠心病(CHD)患者180例，按随机数字表法分为对照组(n=90，给予警示标识)和观察组(n=90，予警示标 识)，对比护理标识使用前后护理人员的风险管理能力、两组患者护理不良事件的发生情况以及护理满意度。结果 使用护理标识后，护理人员的理论分数、实践分数及合格率均显著高于使用护理标识前(P＜0.05)；护理警示标识 干预后，观察组的护理不良事件的发生率显著低于对照组(P＜0.05)；观察组护理满意度(98.9%)明显高于对照组 (83.3%)(P＜0.05)。结论 护理警示标识能减少老年冠心病患者住院期间护理不良事件的发生。

Objective To explore the preventive effects of nursing warning signs on adverse nursing events during hospitalization in elderly patients with coronary heart disease. Methods A total of 180 elderly patients with coronary heart disease (CHD) aged 60 years old and above who were hospitalized in the department of cardiology were selected and divided into control group (n=90, given warning signs) and observation group (n=90, warning signs). The risk management ability of nursing staff, occurrence of adverse nursing events and nursing satisfaction were compared between the two groups before and after application of nursing signs. Results After application of nursing signs, the theoretical score, practice score and qualified rate of nursing staff were significantly higher than before application of nursing signs (P<0.05). After intervention of nursing warning signs, the incidence rate of nursing adverse events in observation group was significantly lower than that in control group (P<0.05). The nursing satisfaction in observation group was significantly higher than that in control group (98.9% vs 83.3%) (P<0.05). Conclusion Nursing warning signs can reduce the occurrence of adverse nursing events during hospitalization of elderly patients with coronary heart disease.
