N2 - The study aimed to determine factors related to ICU mortality in critically ill patients
transferred by Adult Retrieval Victoria (ARV) medical staff. Patients who died in ICU after
interhospital transfer were compared against those who survived.
Methods: This was a retrospective cohort study of ARV cases between 1 January 2009 and 30 June
2010. Retrieval data were linked with data from the ANZICS CORE APD (Australia and
New Zealand Intensive Care Society Centre for Outcome and Resource Evaluation Adult
Patient Database). Victoria Data Linkage (VDL) performed linkage of data. Data included
demographic and clinical data obtained during transfer and clinical data recorded in ICU.
Results: Of the 601 cases transferred by ARV during the study period, 549 cases were eligible for
linkage to 25 543 ANZICS APD case records for the same period. VDL matched 460 of these
cases (83.8 ). Mortality rate in the matched sample was 13.9 . Variables associated with
mortality were: advanced age (odds ratios [OR] 1.02, 95 confidence interval [CI] 1.00?1.04,
P = 0.02), principal referral problem cardiac (OR 1.84, 95 CI 1.02?3.32, P = 0.04), lower
mean arterial blood pressure (OR 0.97, 95 CI 0.95?0.99, P = 0.005) and tachycardia (OR
1.02, 95 CI 1.00?1.03, P = 0.008) on arrival at destination hospital.
Conclusions: Advanced age, lower mean arterial blood pressure and tachycardia towards the completion
of transfer were associated with increased ICU mortality in this population. Clinicians
should be aware of the additional risk for cardiac patients.
