This paper describes a cross-sectional study which examines musculoskeletal symptoms in nurses working in two similar units in a residential care centre for the developmentally disabled. Amongst the 30 nurses who were administered the Nordic Questionnaire, neck and upper limb symptoms had resulted in considerable inability to perform work. In contrast, a similar incidence of reported back symptoms in these nurses had not prevented them from doing their work. An examination of the worker's compensation claims made by nurses from the whole facility showed low back claims to be more common than neck and upper limb claims. It appears that nurses are more likely to make a worker's compensation claim for low back symptoms than neck and upper limb symptoms. In other words, worker's compensation claims do not accurately reflect the types of musculoskeletal symptoms actually experienced by nurses and affecting their ability to do their work. Five nurses from each unit were also observed during the entire morning and afternoon shifts to examine the work load and the effects of fatigue on the musculoskeletal system. Heart rate measurements and ratings of perceived exertion were taken. Activities performed and types of transfers carried out were also recorded. Nurses in one of the units had significantly more reported neck and shoulder symptoms than their counterparts. Observations of a sample of five nurses from each unit also showed higher ratings of perceived exertion in this unit. These differences were possibly confounded by the fact that nurses in the unit which experienced these problems were about 8 cm shorter and about 5 kg lighter than their counterparts. Differences in the work practices in the two units, especially methods of manual handling and use of ergonomic interventions were identified as important contributing factors.
本文描述了一项横断面研究,该研究调查了在一家为发育障碍者提供住宿护理的中心两个类似病房工作的护士的肌肉骨骼症状。在接受北欧问卷调查的30名护士中,颈部和上肢症状导致他们在很大程度上无法开展工作。相比之下,这些护士中报告的背部症状发生率虽与之相似,但并未妨碍他们工作。对整个机构护士提出的工伤赔偿申请进行审查发现,下背部索赔比颈部和上肢索赔更为常见。看来,护士因下背部症状提出工伤赔偿申请的可能性高于颈部和上肢症状。换句话说,工伤赔偿申请并不能准确反映护士实际经历的、影响其工作能力的肌肉骨骼症状类型。还在上午和下午的整个班次对每个病房的5名护士进行了观察,以检查工作量以及疲劳对肌肉骨骼系统的影响。测量了心率并记录了自觉用力程度评分。还记录了所进行的活动和搬运类型。其中一个病房的护士报告的颈部和肩部症状明显多于另一个病房的护士。对每个病房5名护士样本的观察还显示,这个病房的自觉用力程度评分更高。这些差异可能因出现这些问题的病房护士比另一个病房的护士矮约8厘米、轻约5千克这一事实而变得复杂。两个病房工作方式的差异,尤其是人工搬运方法和人体工程学干预措施的使用,被确定为重要的促成因素。
