Abstract
OBJECTIVES: To evaluate short-term outcomes and mortality after interhospital transportation of intensive care patients performed by a mobile intensive care unit (MICU). SETTING: This study was performed in the tertiary care process of interhospital transportation using the local MICU system in the South East of the Netherlands. PARTICIPANTS: Between March 2009 and December 2011, all transports of adult patients being performed by the local MICU centre have been documented; data on 42 variables, including a 24 h follow-up Sequential Organ Failure Assessment (SOFA) score of 368 consecutive interhospital transports of intensive care patients, were recorded. In 24 cases, the follow-up SOFA score was missing, so 344 data sets were included. INTERVENTIONS: No interventions have been done. PRIMARY/SECONDARY OUTCOME MEASURES: Primary outcome measures were the mean SOFA score before and 24 h after transport, and the 24 h post-transport mortality. Moreover, the differences between the groups of 24 h post-transport survivors and non-survivors have been analysed. RESULTS: The mean SOFA score before transport was 8.8 for the whole population and 8.6 for those patients who were alive 24 h after transport, with a mean SOFA score of 8.4 after transport. The adverse events rate was 6.4%. Fourteen patients (4.1%) died within 24 h after transport. Patients in this group had a higher SOFA score, lower pH, higher age and more additional medical support devices than those patients in the survivor group. CONCLUSIONS: The non-significant decrease in the post-transport SOFA score and the lack of an association between transport and 24 h post-transport mortality indicates that in the study setting, interhospital transportation of intensive care patients performed by a MICU system was not associated with a clinically relevant deterioration of the patient.
