ADJUST: A Study on MDT Prognostication

Not Applicable

Completed

• Conditions: Terminal Illness
• Interventions: Other: Advice from another clinician; Other: Advice from the PiPS-B14 prognostic tool

• Registration Number: NCT04568629
• Lead Sponsor: University College, London

Brief Summary

This study investigates how clinicians form intuitive judgements about the prognoses of palliative care patients after receiving advice perceived as coming from either a team member or an algorithm.

Detailed Description

Using the Judge-Advisor System, the investigators will recruit clinicians working in palliative care for adults. Participants will be asked to complete an online survey and review five patient summaries ("vignettes") based on real cases derived from a previous study. Clinicians will be presented with key prognostic information and will be asked to provide an estimate of the probability that the patient will survive for two weeks (0-100%). After providing this initial estimate, participants will receive prognostic advice. While in reality all participants will receive the same advice, participants will be randomised into two groups and these groups will be informed that the advice is either: (1) provided by an algorithm; or (2) provided by a team colleague. Participants will then be given the opportunity to give a second, possibly revised estimate in the light of the advice received.
