Cross-sectional OBJECTIVES: Neurogenic lower urinary tract dysfunction is common among people with spinal cord injury (SCI). Although single-use clean intermittent catheterization is recommended to facilitate routine bladder emptying, catheter re-use is common. Barriers associated with the preparation (i.e., cleaning) of catheters for re-use are unknown. This study examined barriers to catheter re-use in adult individuals with SCI by assessing (1) the time needed to clean a catheter, and (2) the perceived difficulty of the catheter cleaning routine.
Laboratory METHODS: Twenty individuals with chronic SCI ( ≥ 1 year since injury; Group 1 = 10 with tetraplegia; Group 2 = 10 with paraplegia) completed the study. Using a standardized cleaning procedure (i.e., Milton method), catheter cleaning was timed for each participant. Perceived difficulty was assessed using a 5-point Likert scale. Functional impairment was assessed with the Upper Extremity Motor Score (UEMS).
Significant between-group differences were observed for total cleaning time (Group 1 = 1584.1 ± 179.8 s; Group 2 = 1321.0 ± 93.8 s, p = 0.004) and perceived difficulty [Group 1 = 2.6 (2, 3); Group 2 = 2 (1.7, 2.3), p = 0.028]. Total cleaning time was significantly correlated with UEMS (ρ = -0.709, p ≤ 0.001) and perceived difficulty (ρ = 0.468, p = 0.037). UEMS emerged as an independent predictor of total cleaning time (R = 0.745, β = -0.833, p ≤ 0.001).
Preparing catheters for re-use is time-intensive and difficult for people with higher SCI level, severity and more pronounced upper limb motor impairment, which was independently associated with total cleaning time. Performing this routine on a consistent basis would require a substantial time commitment and would have a profoundly negative impact on overall quality of life.
横断面研究
神经原性下尿路功能障碍在脊髓损伤(SCI)患者中很常见。虽然推荐使用一次性清洁间歇性导尿来促进常规膀胱排空,但导管重复使用很常见。对于重复使用导管的准备(即清洁)相关的障碍尚不清楚。本研究通过评估(1)清洁导管所需的时间,以及(2)清洁常规的感知难度,来研究成人 SCI 患者重复使用导管的障碍。
实验室
20 名慢性 SCI 患者(损伤后≥1 年;第 1 组 10 名四肢瘫痪;第 2 组 10 名截瘫)完成了这项研究。使用标准化的清洁程序(即 Milton 法),为每位参与者计时清洁导管。使用 5 分制 Likert 量表评估感知难度。使用上肢运动评分(UEMS)评估功能障碍。
两组间总清洁时间(第 1 组 1584.1±179.8 s;第 2 组 1321.0±93.8 s,p=0.004)和感知难度[第 1 组 2.6(2,3);第 2 组 2(1.7,2.3),p=0.028]有显著差异。总清洁时间与 UEMS 显著相关(ρ=-0.709,p≤0.001)和感知难度(ρ=0.468,p=0.037)。UEMS 是总清洁时间的独立预测因子(R=0.745,β=-0.833,p≤0.001)。
为重复使用准备导管需要花费大量时间,且对 SCI 程度较高、严重程度较高和上肢运动障碍更明显的患者来说较为困难,这与总清洁时间独立相关。如果要持续执行这一常规操作,将需要大量的时间投入,并对整体生活质量产生深远的负面影响。
