To investigate the effects, costs, and feasibility of providing on-site compared with remote meetings to set up hospital sites in a multicenter, surgical randomized controlled trial.
Hospitals were randomized to receive the initial trial setup meetings on-site (i.e., face-to-face) or remotely (i.e., via teleconference). Data were collected on site setup, recruitment, follow-up, and costs for the two methods. The hospital staff experience of trial setup was also surveyed.
Thirty-nine sites were randomized and 33 sites set up to recruit (19 on-site and 14 remote). For sites randomized to an on-site meeting compared with remote meeting respectively, the time from first contact to the first recruit was a median of 246 days (interquartile range [IQR] 196-346] vs. 212 days (IQR 154-266), mean recruitment was 10 participants (median 10, IQR 2-17) vs. 11 participants (median 6, IQR 5-23), and participant follow-up at 12 months was 81% vs. 82%. Sites allocated to an initial on-site visit cost on average £289.83 more to setup.
Remote or on-site visits are feasible for the initial setup meetings with hospitals in a multicenter surgical trial. This embedded trial should be replicated to improve generalizability and increase statistical power using meta-analysis. ISRCTN78899574.
调查在一项多中心外科随机对照试验中,与远程会议相比,提供现场会议以设立医院现场的效果、成本和可行性。
将医院随机分配接受现场(即面对面)或远程(即通过电话会议)初始试验设置会议。两种方法的现场设置、招募、随访和成本数据均进行了收集。还调查了医院工作人员对试验设置的体验。
39 个站点被随机分组,33 个站点进行了招募(19 个现场,14 个远程)。与远程会议相比,随机分配到现场会议的站点的首次接触到首次招募的时间中位数分别为 246 天(四分位距 [IQR] 196-346)和 212 天(IQR 154-266),平均招募人数分别为 10 名参与者(中位数 10,IQR 2-17)和 11 名参与者(中位数 6,IQR 5-23),12 个月时的参与者随访率分别为 81%和 82%。平均而言,分配到初始现场访问的站点设置成本高出 289.83 英镑。
对于多中心外科试验中医院的初始设置会议,远程或现场访问是可行的。这项嵌入式试验应该被复制,以使用荟萃分析提高推广性和增加统计效力。ISRCTN78899574。
