Insights
Interhospital transfer, especially from pediatric intensive care units (PICUs), increases resource use and can impact patient outcomes. Further research is needed to understand transfer decisions and severity factors.
Area of Science:
- Pediatric Critical Care Medicine
- Healthcare Resource Utilization
- Patient Outcomes
Background:
- Interhospital transfer is common for critically ill children requiring specialized care.
- Understanding the impact of transfer on resource use and outcomes is crucial for healthcare planning.
Purpose of the Study:
- To evaluate the effect of interhospital transfer on resource utilization and clinical outcomes in a tertiary pediatric intensive care unit (PICU).
- To compare outcomes and resource consumption between direct admissions and various types of interhospital transfers (e.g., from emergency departments, wards, or other PICUs).
Main Methods:
- Retrospective analysis of 2146 consecutive admissions for sepsis or respiratory failure to a PICU.
- Data collected included demographics, admission source (direct vs. interhospital transfer), and clinical outcomes.
- Admission sources were categorized as direct from the study hospital's emergency department (ED) or interhospital transfers from referring hospital EDs, wards, or PICUs.
Main Results:
- Inter-PICU transfers showed higher crude mortality but not significantly different adjusted mortality compared to direct admissions.
- Emergency department transfers had lower PICU mortality than direct ED admissions.
- All transfer types, particularly inter-PICU transfers, were associated with significantly longer stays and increased use of intensive care technology (P < .01).
Conclusions:
- Interhospital transfer, especially from PICUs, is linked to substantial hospital resource consumption, often correlating with initial illness severity.
- Further prospective research is recommended to identify factors influencing pretransfer illness severity and the decision-making process for interhospital transfers.
Purpose:
The study aimed to examine the effect of interhospital transfer on resource utilization and clinical outcomes at a tertiary pediatric intensive care unit (PICU) among patients with sepsis or respiratory failure.
Materials And Methods:
Data on 2146 consecutive admissions with respiratory failure or sepsis to the PICU were analyzed. Data included demographics, admission source, and outcomes. Admission source was classified as interhospital transfer from the emergency departments (ED), wards, or PICUs of referring hospitals; or from the study hospital ED (direct).
Results:
Compared with direct admissions, inter-PICU transfers had higher crude mortality (odds ratio, 1.93; 95% confidence interval, 1.31-2.84) but not significant mortality difference (odds ratio, 1.16; 95% confidence interval, 0.71-1.86) after adjusting for illness severity, age, and sex. Conversely, ED transfers had lower PICU mortality than direct ED admissions. Children with transfer admissions stayed significantly longer and used more intensive care technology in the study PICU than children directly admitted (P < .01). In comparisons within quartiles of mortality risk, inter-PICU transfers had longer hospitalization and higher mortality in all but the highest quartile.
Conclusions:
Interhospital transfer, particularly inter-PICU transfer, was associated with significant hospital resource consumption that often correlated with admission illness severity. Future prospective studies should identify determinants of pretransfer illness severity and investigate decision making underlying interhospital transfer.
