Correlation between sleep cognition and sleep quality in THA or TKA patients

目的 探讨髋、膝关节置换患者睡眠认知与睡眠质量的相关性.方法 采用目的抽样法选择2016年1-3月在四川大学华西医院骨科的90例髋、膝关节置换患者,采用睡眠信念态度量表（DBAS-16）和匹兹堡睡眠质量指数量表（PSQI）进行问卷调查,分析髋、膝关节置换患者睡眠态度信念与睡眠质量的相关性.结果 不同文化程度的患者睡眠认知差异有统计学意义（P〈0.05）.髋、膝关节置换患者DBAS评分与睡眠质量差异有统计学意义（t=19.49,P〈0.01）,夸大失眠的不良后果是其主要的错误睡眠认知（t=5.25,P〈0.05）,DBAS评分与PSQI成分因子睡眠时间、睡眠障碍、催眠药物的使用、日间功能评分之间均有相关性（P〈0.05）.结论 不良的睡眠认知严重危害了髋、膝关节置换患者的睡眠质量,护理人员应及时识别患者错误的睡眠认知,采用针对性的护理措施提高患者的睡眠质量.

Objective To probe into the correlation between sleep cognition and sleep quality in THA or TKA patients. Methods Totally 90 THA or TKA patients were chosen by purposive sampling in Department of Orthopaedics,West China Hospital of Sichuan University from January to March in 2016, and were investigated by abbreviated version of dysfunctional beliefs and attitudes about sleep scale-16（DBAS-16） and Pittsburgh sleep quality index scale（PSQI）. Correlation between sleep cognition and sleep quality in THA or TKA patients were analyzed. Results There were significant differences in sleep cognition among the patients with different educational levels （P〈0.05）. The score of DBAS and the sleep quality were statistically different in THA or TKA patients （t=19.49,P〈0.01）. Exaggerated adverse consequence of insomnia was the main mistake of sleep cognition （t=5.25,P〈0.01）. The score of DBAS was significantly correlated with the sleep time, sleep disorders, using of hypnotic drugs and daytime function of PSQI （P〈0.05）. Conclusions Poor sleep cognition seriously affects sleep quality in THA or TKA patients. Nursing staff should promptly identity patients＆#39; sleep cognitive errors,and apply targeted nursing measures to improve the quality of sleep.
