BACKGROUND Follow-up after artificial joint replacement greatly helps achieve surgical outcomes. Mobile internet technology and mobile terminal equipment may increase the effectiveness of artificial joint replacement. However, only a few studies have evaluated the effectiveness of this technology. We aimed to analyze the reasons and outcomes of patients who used the instant messaging platform after undergoing artificial joint replacement. METHODS Among the 548 cases of arthroplasty (250 hips, 298 knees) performed between December 2015 and June 2018 in the Department of Joint Surgery of our institution; 358 (164 hip joints, 194 knee joints) participated in instant messaging platform consultation, whereas the remaining 190 (86 hip joints, 104 knee joints) participated in traditional telephone consultation, as a control group. Follow-up time was from December 2015 to August 2018 (follow-up period was 2-32 months). Data on age, sex, type of surgery, date of surgery, date of discharge, and length of hospital stay were collected from electronic medical records. RESULTS We analyzed the consultation contents of 358 patients who participated in instant messaging platform consultation. Counseling was mainly related to pain (13.6%), appointment review (12.4%), activity problems (10.5%), and incision problems (8.9%). Most problems were resolved through online guidance, with 8.4% of patients requiring only outpatient treatment and 2.5% of patients requiring rehospitalization. A total of 190 patients were followed up through traditional telephone consultation; 6.8% of patients required outpatient department treatment and 7.4% were eventually re-admitted. CONCLUSION The instant messaging platform consultation service effectively informs patients of potential postoperative problems and helps resolve them. It allows early detection and management of postoperative adverse events, including problems related to medication, wound, and activity, thereby effectively reducing readmission rate.

用于全关节置换术后患者术后随访的现代即时通讯平台可能会降低再次入院率。

背景技术人工关节置换后的随访极大地有助于实现手术结果。移动互联网技术和移动终端设备可以提高人工关节置换的有效性。但是，只有很少的研究评估了该技术的有效性。我们旨在分析在进行人工关节置换后使用即时通讯平台的患者的原因和结果。方法2015年12月至2018年6月在我院关节外科进行的548例关节置换术（250髋，298膝）中; 358个（髋关节164个，膝关节194个）参加了即时消息平台咨询，而其余190个（髋关节86个，膝关节104个）参加了传统电话咨询，作为对照组。随访时间为2015年12月至2018年8月（随访时间为2-32个月）。从电子病历中收集了有关年龄，性别，手术类型，手术日期，出院日期和住院时间的数据。结果我们分析了358名参加即时通讯平台咨询的患者的咨询内容。心理咨询主要涉及疼痛（13.6％），约会审查（12.4％），活动问题（10.5％）和切口问题（8.9％）。大多数问题通过在线指导解决，只有8.4％的患者仅需门诊治疗，而2.5％的患者需要再次住院。通过传统的电话咨询方式对190名患者进行了随访。6.8％的患者需要门诊治疗，而7.4％的患者最终被重新接纳。结论即时通讯平台咨询服务可以有效地告知患者潜在的术后问题，并帮助解决这些问题。它可以及早发现和处理术后不良事件，包括与用药，伤口和活动有关的问题，从而有效降低再次入院率。
