There is agreement, although little evidence, that consistently positioning stroke patients in allegedly reflex-inhibiting positions is therapeutic and will enhance functional recovery. The nursing staff, therefore, needs to know and implement these postures and understand their potential underlying value. We examined nurses' knowledge of and practice in positioning stroke patients before and after a formal teaching intervention.
In a quasi-experimental study, 38 stroke patients and 59 nursing staff members (44 trained nurses and 15 healthcare assistants) from 6 wards were studied. The wards were randomly allocated to experimental or control status. Patients were assessed on entry into the study by use of a range of measures to establish group equivalence. Nineteen aspects of their position were documented at intervals throughout their stay with a previously developed observational tool. One thousand sets of observations of patient position were made. Using 2 questionnaires, the nurses' knowledge of the terminology used to denote posture and of issues relating to the moving and positioning of stroke patients was assessed before, immediately after, and 3 months after a package of formal teaching was implemented on the experimental wards. Nurse knowledge and patient position were used as the main outcome measures.
Immediately after teaching, nurses in the experimental group scored significantly higher than those in the control group on the terminology questionnaire (P < 0.05) and the moving and positioning questionnaire (P < 0.001). Three months later, the experimental group scored higher on the latter questionnaire only (P < 0.005). The positioning of patients in the experimental group was improved overall after the teaching (P < 0.0005), and improvements to specific parts of the body were noted.
It was possible to effect a degree of change in the nurses' knowledge of and practice in the positioning of stroke patients. However, the quality of patient positioning remained variable. More effective ways of improving positioning need to be developed. Only then can the effects of recommended positioning be evaluated.
尽管证据不足,但人们一致认为,持续将中风患者置于所谓的反射抑制体位具有治疗作用,能够促进功能恢复。因此,护理人员需要了解并实施这些体位,并理解其潜在的价值。我们调查了在正式教学干预前后,护士对中风患者体位摆放的知识掌握情况及实际操作情况。
在一项准实验研究中,对来自6个病房的38名中风患者和59名护理人员(44名注册护士和15名医疗辅助人员)进行了研究。这些病房被随机分为实验组和对照组。患者在进入研究时通过一系列测量方法进行评估,以确保两组具有可比性。在患者住院期间,使用先前开发的观察工具,每隔一段时间记录其体位的19个方面。共进行了1000次患者体位观察。通过两份问卷,在实验组实施一套正式教学之前、之后即刻以及3个月后,评估护士对表示体位的术语以及与中风患者移动和体位摆放相关问题的了解程度。护士的知识水平和患者的体位作为主要观察指标。
教学后即刻,实验组护士在术语问卷(P < 0.05)和移动与体位问卷(P < 0.001)上的得分显著高于对照组。3个月后,实验组仅在后者问卷上得分更高(P < 0.005)。教学后,实验组患者的体位总体上有所改善(P < 0.0005), 身体特定部位也有改善。
有可能在护士对中风患者体位摆放的知识和实践方面实现一定程度的改变。然而,患者体位摆放的质量仍然参差不齐。需要开发更有效的改善体位摆放的方法。只有这样才能评估推荐体位的效果。
