Interhospital transfers to intensive care units (ICUs) do not show differences in length of stay or mortality based on ICU subspecialty. Age and transfer from another ICU were associated with increased mortality and length of stay, respectively.
Area of Science:
- Critical care medicine
- Health services research
Background:
- Interhospital transfers, especially to intensive care units (ICUs), are linked to increased length of stay and mortality.
- While surgical ICUs show higher mortality for transferred patients, differences across other ICU types are not well-established.
Purpose of the Study:
- To investigate variations in length of stay and mortality among different intensive care unit (ICU) subspecialties for transferred patients.
Main Methods:
- Retrospective analysis of a critical care transfer data repository.
- Utilized multiple and logistic regression to identify factors influencing length of stay and mortality.
Main Results:
- No significant differences in length of stay or mortality were observed based on ICU subspecialty.
- Each year increase in age correlated with an 8.6% rise in mortality odds (P = .002).
- Transfers from an ICU were associated with a 6.3-day longer length of stay (P < .001), and non-Caucasian patients had a 3.4-day shorter length of stay (P = .012).
Conclusions:
- ICU subspecialty does not appear to influence length of stay or mortality for transferred patients.
- Further research is required to elucidate the impact of sending unit type and race on length of stay.
- Additional factors predicting mortality in surgical ICUs need identification.
