Objective: To evaluate the effectiveness of an intervention combining Root Cause Analysis (RCA)–based quality management and Psychological Capital (PsyCap) theory in reducing communication interruptions and improving communication quality and teamwork in surgical safety check teams. Methods: Eighty surgical team members from a tertiary hospital (January 2025 - December 2025.) were assigned to a control group or an intervention group according to operating room allocation (40 per group). The control group followed routine surgical safety check procedures, whereas the intervention group additionally received an RCA-guided workflow analysis and a PsyCap-based communication enhancement program. Post-intervention outcomes included communication interruption rate, execution quality and efficiency of safety checks, Psychological Capital Questionnaire (PCQ-24) scores, and TeamSTEPPS Teamwork Perceptions Questionnaire (T-TPQ) scores. Results: The intervention group demonstrated a significantly lower communication interruption rate compared with the control group (P＜0.05). Execution quality and communication efficiency were significantly improved in the intervention group (P＜0.001). PCQ-24 total and subscale scores were significantly higher in the intervention group than in the control group (P＜0.001), as were T-TPQ total and subscale scores (P＜0.001). Conclusion: Integrating RCA-based workflow optimization with PsyCap-oriented psychological and behavioral training can effectively enhance communication quality, reduce interruptions, and strengthen teamwork in surgical safety check teams. The combined model has strong applicability and potential for wider clinical promotion.

目的 探讨达格列净在行经皮冠状动脉介入治疗（Percutaneous Coronary Intervention，PCI）后2型糖尿病（Type 2 Diabetes Mellitus,T2DM）伴不稳定型心绞痛（Unstable Angina，UA）患者中的应用价值及短期心功能改善效果。方法 本研究为单中心、随机对照试验，纳入90例PCI术后2型糖尿病合并不稳定型心绞痛患者，随机分为达格列净组（n=43）和二甲双胍组（n=47），规范调整降糖药物保证降糖强度一致。治疗期间及治疗后6-12个月通过心脏彩超测量左心室射血分数（Left Ventricular Ejection Fraction，LVEF）、左室舒张末期内径（Left Ventricular End-Diastolic Diameter，LVEDD），并采集静脉血样检测N端B型利钠肽前体（N-terminalpro-Brain Natriuretic Peptide，NT-proBNP）水平，以评估心功能变化。 结果 PCI治疗后的6-12个月随访中，观察组NT-proBNP（P<0.01）显著降低，左心室射血分数LVEF（P<0.01）显著提升。与对照组相比：观察组NT-ProBNP水平明显下降（P<0.01），且低于对照组。结论 在PCI术后合并不稳定型心绞痛的T2DM患者中，加用达格列净治疗可显著改善NT-proBNP和LVEF等心功能替代指标，且安全性良好。

Objective:To explore the application value of dapagliflozin and its short-term cardiac function improvement effect in patients with type 2 diabetes mellitus (T2DM) combined with unstable angina (UA) after percutaneous coronary intervention (PCI). Methods: This was a single-center, randomized controlled trial. A total of 90 patients with type 2 diabetes mellitus (T2DM) complicated with unstable angina (UA) after percutaneous coronary intervention (PCI) were enrolled and randomly assigned to a dapagliflozin group (n=43) and a metformin group (n=47). Hypoglycemic agents were adjusted routinely to ensure consistent glycemic control intensity between the two groups. During treatment and at 6–12 months after treatment, left ventricular ejection fraction (LVEF) and left ventricular end-diastolic diameter (LVEDD) were measured by echocardiography, and venous blood samples were collected to determine the level of N-terminal pro-Brain Natriuretic Peptide (NT-proBNP) for the evaluation of cardiac function changes. Results: During the 6-month follow-up after PCI treatment, the N-terminal pro-brain natriuretic peptide (NT-proBNP) level in the observation group decreased significantly (P<0.01), and the left ventricular ejection fraction (LVEF) increased significantly (P<0.01).Compared with the control group, the NT-proBNP level in the observation group was notably lower (P<0.01) and also remained below that of the control group. Conclusion: For type 2 diabetes mellitus (T2DM) patients complicated with unstable angina pectoris after PCI, adjuvant treatment with dapagliflozin for 6 months can significantly improve cardiac function surrogate markers such as NT-proBNP and LVEF, with favorable safety profile.
