简要总结
This study evaluates whether an online training resource can improve the performance of medical students in recognising imminently dying palliative care patients.
详细描述
Clinicians are routinely asked to provide survival estimates for palliative care patients, but recognition of imminent death (last 72 hours of life) is often inaccurate. We developed an online training resource, based on a previous study that identified the symptoms or signs that were most influential in forming expert palliative care doctors' prognostic decisions about imminent death.
This double-blind randomised controlled trial will evaluate the effectiveness of this online training resource in improving the performance of medical students in recognising imminently dying palliative care patients.
Participants are asked to visit the study website and review three series of vignettes describing patients referred to palliative care. For each vignette, participants are asked to provide an estimate (0-100%) about the probability that the patient will die in the next 72 hours. After the first series of vignettes, students randomised to the intervention arm are given access to an online training resource showing how experts weighted the relative importance of symptoms and signs. All participants are asked to complete a second series of vignettes. After two weeks, all participants are asked to return to the website and complete a third series of vignettes to assess if any effect has been maintained.

研究组 & 干预措施
Intervention group
The intervention is an online training resource to improve the recognition of imminent death in palliative care patients. The intervention should take approximately 15 minutes to complete. During this time, the participants who are in the intervention arm will be shown the results of a previous study which identified how expert palliative care doctors recognise imminently dying palliative care patients. The intervention will be implemented via the website, immediately after participants have completed the first set of vignettes.
干预措施: Online training resource (Other)
Control group
The participants assigned to the control group will not receive this additional information and will simply be informed that they are approximately half way through the task and will be asked to continue on to the next set of vignettes.
结局指标
主要结局
Survival estimates - immediate effect
时间窗: Second series of vignettes, taking into account the estimates from the first series. Students can participate at their convenience and will have a four week window to complete the first and second series of vignettes.
The primary outcome will be a continuous survival estimate provided from the students for the second series of vignettes; ranging from 0-100%.
次要结局
- Survival estimates - follow-up(Third series of vignettes, taking into account the estimates from previous series. Two weeks after completing the first and second series of vignettes, students will be asked to complete a third series of vignettes within a four week window.)
- Level of expertise(Change over time including all three series of vignettes. Students are given a four week window to complete the first and second series of vignettes. After two weeks, they will be asked to complete a third series of vignettes within a four week window.)
- Cue weighting(Change over time including all three series of vignettes. Students are given a four week window to complete the first and second series of vignettes. After two weeks, they will be asked to complete a third series of vignettes within a four week window.)
