Characterizing ICU-like profiles of very old patients hospitalized in medical intermediate care units in France: A clustering analysis of a nationwide population-based study
Authors' conclusion
A substantial number of very old patients were admitted to IMCU despite meeting ICU-level criteria.
Study context
- Population
- Critically ill patients ≥80 y.o hospitalised in medical intermediate care units (IMCUs) in France over a two-year period
- Participants
- 202,976 very old IMCU patients
- Exposure
- "ICU-like" IMCU patients vs propensity-matched ICU patients
- "ICU-like" IMCUn = 23,508
- Outcome
- Clusters (phenotypes) of very old IMCU patients and factors associated with IMCU rather than ICU admission
Methodological detailslatent class analysis, propensity-score matched, multivariate logistic regression
- Latent class analysis
- Propensity-score matched
- Multivariate logistic regression
Main finding
As reported in the abstract
- IMCU phenotypes identified
- seven
- "ICU-like" population share of cohort
- 11.6%
Observational data: associations, not effects.
