血泪是指因各种原因导致眼部流出血性泪液的症状，其病因和临床表现复杂多样，往往涉及多学科多专业。不同病因引起的血泪，无论是临床表现，还是诊治方法均差异很大。为了向临床医生提供可参考的血泪临床诊疗流程，中国医师协会眼科医师分会泪器病专业委员会及中国中西医结合学会眼科专业委员会泪器病学组组织有关专家以临床实践经验为基础，经过认真讨论建立本共识，对血泪的病因、临床特征及诊疗流程提出指导性意见。

Bloody tears refers to the symptoms of blooding tears flowing from the eye due to various reasons. Its etiology and clinical manifestations are complex and diverse, often involving multiple disciplines and specialties. In order to provide clinicians with a reference for the clinical diagnosis and treatment process of bloody tears, Lacrimal Diseases Professional Committee of Ophthalmologist Branch of Chinese Medical Doctor Association and Lacrimal Diseases Group of Ophthalmic Professional Committee of Chinese Association of Integrated Medicine organized relevant experts to establish this consensus based on clinical practice after serious discussion, and put forward guiding opinions on the etiology, clinical characteristics, and diagnosis and treatment process of bloody tears.

目的：探讨PDCA循环管理模式在优化白内障日间患者诊疗流程中的应用与成效。方法：选取中山大学中山眼科中心白内障病区2018年9月至2019年12月收治的白内障日间患者400例作为试验对象，选择2018年9月至2019年4月200例患者作为优化前组，选择实施PDCA循环管理模式后的2019年5月至2019年12月的200例患者作为优化后组。统计并比较两组患者实施前后的术前检查时长、住院时长、术后第1天复诊路径及患者满意度。结果：PDCA循环管理法实施了7个月后，患者术前检查时长由优化前的(2.94±2.12) h降至(2.09±0.93) h，住院时长由优化前的(22.73±1.14) h 降至(5.22±1.29) h，差异均具有统计学意义( P <0.001)；患者满意度由优化前的92%上升至96%(P<0.05)；术后第1天，患者复查所需行走的路径缩短，由以前的172 m降至129 m。结论：实施PDCA循环管理模式能有效地改善白内障日间患者的诊疗流程，缩短患者诊疗时间，提高患者的满意度，值得临床推广。

Objective: To explore the application and effect of Plan-Do-Check-Act (PDCA) cycle management mode in optimizing the diagnosis and treatment process of cataract patients with daytime surgery. Methods: A total of 400 cases of patients with daytime surgery admitted to Department of Cataract, Zhongshan Ophthalmic Center,Sun Yat-sen University from September 2018 to December 2019 were selected as the experimental subjects. 200 patients from September 2018 to April 2019 were selected as the pre-optimization group, and 200 patients from May 2019 to December 2019 after the implementation of the PDCA cycle management mode were selected as the post-optimization group. Time of preoperative examination, length of hospital stay, the follow-up path in the first day after surgery and patient satisfaction were statistically compared between the two groups before and after implementation. Results: Seven months after the implementation of PDCA cycle management mode, the preoperative examination time decreased from (2.94±2.12) h to (2.09±0.93) h, and the length of hospital stay decreased from (22.73±1.14) h to (5.22±1.29) h, and the differences were statistically significant (P<0.001); the patients’ satisfaction increased from 92% to 96% (P<0.05); the follow-up path in the first day after operation was changed from the 13th floor (172 m) to the 3rd floor (129 m). Conclusion: The implementation of PDCA cycle management mode can effectively improve the diagnosis and treatment process of cataract patients with daytime surgery, shorten the diagnosis and treatment time and improve the satisfaction of patients, so it is worthy of clinical promotion.
