目的探讨提高晚期老年痴呆患者家居安全，减少并发症发生率的有效方法。方法将47例晚期老年痴呆患者随机分为观察组24例，对照组23例。对照组采用常规出院指导，出院后不进行护理干预；观察组对患者、家庭照顾者进行为期1年的老年痴呆相关知识和护理技能、家居安全等家庭护理干预，指导照顾者为患者进行预防肺部感染、泌尿系感染、压疮，肢体功能锻炼，并对照顾者进行心理疏导等。比较两组干预1年期间全身并发症及家居安全意外发生率。结果观察组肺部感染、泌尿系感染、压疮发生率及家居安全意外发生率显著低于对照组（P〈0．05，P〈0．01）。结论充分有效的家庭护理干预可减少晚期老年痴呆患者并发症的发生，延缓病情进展，提高其家居安全。

英文摘要：

Objective To guarantee home safety of patients with advanced Alzheimerrs disease（AD）, and to minimize the rates of complication. Methods A total of 47 AD patients were randomized into an observation group （n=4） and a control group （n=23）. Patients in the control group were given routine instruction at discharge, and no further nursing care was given to them after discharge. Patients in the observation group were subjected to family intervention for one year including teaching of AD knowledge, nursing skills and home safety. And the care givers of the patients were arranged to learn such knowledge as bow to prevent infection of the lungs and the urinary tract, how to prevent pressure ulcer, and how to assist patients to perform rehab training. The care givers were emotionally supported by the researchers. The rates of complications and homebound accidents within one year between the two groups were compared. Results The rates of lung infection and urinary tract infection, incidence of pressure ulcers and homebound accidents were significantly lower in the observation group than in the control group （P〈0.05 ,P〈0.01）. Conclusion Effective family interventions can reduce the rates of complication among bomebound AD patients, delay disease progress, and guarantee home safety for them.
