Discriminative Accuracy of Physician and Nurse Predictions for Survival and Functional Outcomes 6 Months After ICU Admission
Detsky 2017 trial design and results
Design
Prospective cohort study
Treatment
Physician and nurse predictions of 6-month survival and functional outcome
Control
Observed outcomes at 6 months
Population
303 patients of 340 approached, median age 62, 57% men, 32% African American; follow-up completed for 299 (99%)
Follow-up
6 months
Primary endpoint
Discriminative accuracy of clinician predictions for survival and functional outcomes
Result
Follow-up was completed for 299 of 303 patients (99%). Clinician predictions discriminated survival reasonably well but were substantially less accurate for functional outcomes such as cognition and ability to return home.
Secondary endpoints
Accuracy by clinician type, confidence and accuracy
ICU physicians' and nurses' discriminative accuracy in predicting 6-month outcomes of critically ill patients varied depending on the outcome being predicted and confidence of the predictors. Further research is needed to better understand how clinicians derive prognostic estimates of long-term outcomes.
The trial authors, in the published abstract
How it has aged
Directly relevant to conversations held every day at ICU bedsides. Families rarely ask only whether the patient will live; they ask what life will look like — the question clinicians answer least reliably. Worth knowing before offering a confident prognosis.
