Information handoff and outcomes of critically ill patients transferred between hospitals.
Patients transferred between hospitals are at high risk of adverse events and mortality. This study aims to identify which components of the transfer handoff process are important predictors of adverse events and mortality. ⋯ Documentation completeness is associated with improved outcomes and resource utilization in patients transferred between hospitals.

Immortal time bias in observational studies of time-to-event outcomes.
The purpose of the study is to show, through simulation and example, the magnitude and direction of immortal time bias when an inappropriate analysis is used. ⋯ To minimize the risk of immortal time bias in observational studies of survival outcomes, we strongly suggest time-dependent exposures be included as time-dependent variables in hazard-based analyses.
