Abstract:

Objective To construct an intervention program for diabetic retinopathy（DR） patients undergoing surgery based on the theory of ‘Timing It Right’. Methods Guided by the theory of ‘Timing It Right’，based on literature review and semi-structured interview，the first draft of the intervention program was formulated. From December 2022 to February 2023，15 medical and nursing experts in ophthalmology and endocrinology from 5 provinces（cities） in Zhejiang，Sichuan，Shanxi，Chongqing and Shanghai were interviewed by Delphi expert for 2 rounds to seek their advice and revision，and the final draft was formed. Results The effective recovery rate of 2 rounds of expert consultations was 93.75% and 100%. The authority coefficients were 0.87. The importance and feasibility of Kendall’W coordination coefficients were 0.325，0.138 and 0.193，0.141 in 2 rounds，respectively（P<0.001）. The finalized intervention program consisted of 6 months，which included 5 first-level items，18 second-level items and 43 third-level items. Conclusion The intervention program for DR patients undergoing surgery based on the theory of ‘Timing It Right’ is reliable，scientific，feasible and practical，and it can meet the needs of such patients，providing a reference for improving their self-management ability，improving their negative emotions and delaying disease progression.

摘要：

目的 基于时机理论，构建糖尿病视网膜病变手术患者的护理干预方案。 方法 以时机理论为指导，在文献研究、半结构式访谈的基础上拟订干预方案初稿。2022年12月—2023年2月对浙江省、四川省、山西省、重庆市、上海市5个省（市）的15名眼科和内分泌科的医疗和护理专家进行两轮德尔菲专家函询，形成方案终稿。 结果 两轮专家函询问卷的有效回收率分别为93.75%和100%，专家权威系数为0.87，两轮函询条目重要性和可行性的肯德尔和谐系数分别为0.325、0.138和0.193、0.141，均P<0.001。最终形成的干预方案周期为6个月，包含5个一级条目、18个二级条目、43个三级条目。 结论 基于时机理论构建的糖尿病视网膜病变手术患者护理干预方案具有可靠性、科学性、可行性和实用性，可满足患者的护理需求，并为提高其自我管理能力、改善其负性情绪、延缓疾病进展提供参考。
