目的研究基于服务流程设计的全程管理对全膝关节置换术患者疼痛、功能、满意度及并发症发生等的影响。方法选取2021年4月–2022年3月在四川大学华西医院骨科接受单侧全膝关节置换术的患者204例,使用随机数字表法分为普通组和全程管理组...目的研究基于服务流程设计的全程管理对全膝关节置换术患者疼痛、功能、满意度及并发症发生等的影响。方法选取2021年4月–2022年3月在四川大学华西医院骨科接受单侧全膝关节置换术的患者204例,使用随机数字表法分为普通组和全程管理组各102例。普通组患者接受传统围手术期管理,全程管理组患者接受基于服务流程设计优化后的全程管理。比较两组患者一般资料,术后3 d及术后3、8、12周的视觉模拟疼痛评分(VAS)、膝关节伸屈活动度、特种外科医院膝关节评分(HSS)、患者满意度调查问卷简表(PSQ-18)评分、术后12周上下楼梯能力以及并发症发生情况等。结果两组患者一般资料及入组时的基线数据比较差异无统计学意义(P>0.05)。两组患者术前及术后3 d HSS评分、关节活动度及VAS疼痛评分差异无统计意义(P>0.05),但在术后3、8、12周时全程管理组评分均优于普通组,差异有统计学意义(P<0.05)。同时,在术后12周时全程管理组患者较普通组具有更好的上下楼梯能力,差异有统计学意义(P<0.001)。在满意度方面,全程管理组患者在术后3 d,术后3、8、12周时满意度均优于普通组(P<0.001)。结论基于服务流程设计的全程管理对减轻膝关节置换术患者疼痛、增加活动度、改善功能、提高满意度和减少并发症等具有积极作用。展开更多
