The aim of this study was to (i) describe registered nurses' and assistant nurses' repositioning skills with regard to their existing attitudes to and theoretical knowledge of pressure ulcer (PU) prevention, and (ii) evaluate if the continuous bedside pressure mapping (CBPM) system provides staff with a pedagogic tool to optimise repositioning. A quantitative study was performed using a descriptive, comparative design. Registered nurses (n = 19) and assistant nurses (n = 33) worked in pairs, and were instructed to place two volunteers (aged over 70 years) in the best pressure-reducing position (lateral and supine), first without viewing the CBPM monitor and then again after feedback. In total, 240 positionings were conducted. The results show that for the same person with the same available pressure-reducing equipment, the peak pressure varied considerably between nursing pairs. Reducing pressure in the lateral position appeared to be the most challenging. Peak pressures were significantly reduced, based on visual feedback from the CBPM monitor. The number of preventive interventions also increased, as well as patients' comfort. For the nurses as a group, the knowledge score was 59·7% and the attitude score was 88·8%. Real-time visual feedback of pressure points appears to provide another dimension to complement decision making with respect to PU prevention.
（i）根据注册护士和助理护士对压疮（PU）预防的现有态度和理论知识，描述他们的重新定位技能；（ii）评估连续床边压力映射（CBPM）系统是否为工作人员提供一种优化重新定位的教学工具。采用描述性、比较性设计进行了一项定量研究。注册护士（n = 19）和助理护士（n = 33）两两一组工作，并被要求将两名志愿者（年龄超过70岁）置于最佳减压体位（侧卧位和仰卧位），首先不查看CBPM监测器，然后在获得反馈后再次进行。总共进行了240次定位。结果表明，对于使用相同减压设备的同一个人，护理组之间的峰值压力差异很大。在侧卧位时减压似乎最具挑战性。根据CBPM监测器的视觉反馈，峰值压力显著降低。预防性干预的次数也增加了，患者的舒适度也提高了。作为一个群体，护士的知识得分是59.7%，态度得分是88.8%。压力点的实时视觉反馈似乎为压疮预防决策提供了另一个补充维度。
