Decentralised services using outreach clinics or modern technology are methods to reduce both patient transports and costs to the healthcare system. Telemedicine consultations via videoconference are one such modality. Before new technologies are implemented, it is important to investigate both the quality of care given and the economic impact from the use of this new technology. The aim of this clinical trial was to study the quality of planned remote orthopaedic consultations by help of videoconference.
We performed a randomised controlled trial (RCT) with two parallel groups: video-assisted remote consultations at a regional medical centre (RMC) as an intervention versus standard consultation in the orthopaedic outpatient clinic at the University Hospital of North Norway (UNN) as a control. The participants were patients referred to or scheduled for a consultation at the orthopaedic outpatient clinic. The orthopaedic surgeons evaluated each consultation they performed by completing a questionnaire. The primary outcome measurement was the difference in the sum score calculated from this questionnaire, which was evaluated by the non-inferiority of the intervention group. The study design was based on the intention to treat principle. Ancillary analyses regarding complications, the number of consultations per patient, operations, patients who were referred again and the duration of consultations were performed.
Four-hundred patients were web-based randomised. Of these, 199 (98 %) underwent remote consultation and 190 (95 %) underwent standard consultation. The primary outcome, the sum score of the specialist evaluation, was significantly lower (i.e. 'better') at UNN compared to RMC (1.72 versus 1.82, p = 0.0030). The 90 % confidence interval (CI) for the difference in score (0.05, 0.17) was within the non-inferiority margin. The orthopaedic surgeons involved evaluated 98 % of the video-assisted consultations as 'good' or 'very good'. In the ancillary analyses, there was no significant difference between the two groups.
This study supports the argument that it is safe to offer video-assisted consultations for selected orthopaedic patients. We did not find any serious events related to the mode of consultation. Further assessments of the economic aspects and patient satisfaction are needed before we can recommend its wider application.

利用外展诊所或现代技术提供的分散式服务是减少患者交通费用和医疗系统成本的方法。通过视频会议进行的远程医疗咨询就是这样一种方式。在实施新技术之前,重要的是要调查所提供护理的质量以及使用这项新技术的经济影响。本临床试验的目的是借助视频会议研究计划中的远程骨科会诊的质量。
我们进行了一项随机对照试验(RCT),分为两个平行组:在区域医疗中心(RMC)进行视频辅助远程会诊作为干预组,与挪威北部大学医院(UNN)骨科门诊的标准会诊作为对照组。参与者是被转诊或安排在骨科门诊会诊的患者。骨科医生通过填写问卷对他们进行的每次会诊进行评估。主要结局指标是根据该问卷计算的总分差异,通过干预组的非劣效性进行评估。研究设计基于意向性分析原则。对并发症、每位患者的会诊次数、手术、再次转诊的患者以及会诊时长进行了辅助分析。
400名患者通过网络随机分组。其中,199名(98%)接受了远程会诊,190名(95%)接受了标准会诊。主要结局指标,即专科评估的总分,在UNN显著低于RMC(分别为1.72和1.82,p = 0.0030)。得分差异的90%置信区间(CI)为(0.05,0.17),在非劣效界值范围内。参与的骨科医生将98%的视频辅助会诊评为“良好”或“非常好”。在辅助分析中,两组之间没有显著差异。
本研究支持这样的观点,即对选定的骨科患者提供视频辅助会诊是安全的。我们未发现与会诊方式相关的任何严重事件。在推荐其更广泛应用之前,需要进一步评估经济方面和患者满意度。
