This model includes the classical risk model and the Pólya-Aeppli risk model as special cases. The objective is to find a dividend policy so as to maximize the expected discounted value of dividends which are paid to the shareholders until the company is ruined. We show that under some conditions the optimal dividend strategy is formed by a barrier strategy. Moreover, two conjectures are proposed.展开更多
目的探讨重症监护室(intensive care unit,ICU)住院患者中应用循环质控理念联合风险管理模式的效果。方法选取2023年1—5月寿光市人民医院ICU住院患者335例作为对照组,实施常规医院感染管理;选取2023年6—12月ICU住院患者340例作为干预...目的探讨重症监护室(intensive care unit,ICU)住院患者中应用循环质控理念联合风险管理模式的效果。方法选取2023年1—5月寿光市人民医院ICU住院患者335例作为对照组,实施常规医院感染管理;选取2023年6—12月ICU住院患者340例作为干预组,实施循环质控理念联合风险管理模式。比较2组管理质量、风险事件、医院感染发生率及患者满意度。结果干预组管理质量(感染监测、组织管理、风险评估、制度建设)评分高于对照组(P<0.05);干预组风险事件发生率(1.47%)低于对照组(4.48%)(P<0.05);干预组医院感染发生率(3.82%)低于对照组(7.46%)(P<0.05);干预组患者满意度(98.24%)低于对照组(95.52%)(P<0.05)。结论循环质控理念联合风险管理模式应用于ICU住院患者中,可提高管理质量,减少风险事件与医院感染发生,促进患者满意度提升,体现了《ICU十大安全目标》的执行标准。展开更多
