Background and aims: Interhospital transport adds additional risks for critical children, much more if untrained staffs do it. Aims: Our aim was to describe the characteristics of interhospital transport of critically ill children referred to a Latin-American tertiary hospital. Methods: Prospective descriptive study. All patients under 14 years old, referred from different hospitals for Paediatric Intensive Care Unit (PICU) between January-August 2013, were included. We described referral characteristics, evolution and monitoring during transport, ambulances supplies, transport staff training and clinical characteristics at admission and clinical evolution. Ethics-committee approved this project. Results: We included 111 children. Eighty-one patients (73%) were not previously accepted by PICU staff and arrived without beds availability. Eleven patients (10%) were transported in more than one vehicle including commercial flights. Median of transport time was 60 minutes (Range: 4–580). One-third of patients had no monitoring during transport. Forty-eight patients were intubated at first hospital, while 2 during transport. Sixteen of intubated (32%) had monobronchial intubation. Of 61 non-intubated children, 17 (27,8%) needed immediate intubation at admission. Eleven (9,9%) children had hypothermia. Half of children had clinical or technical adverse events during transport, while 84 (75,7%) had adverse events detected at admission. One child died during transport. None of transport staff had training in critically ill children. Conclusions: All types of adverse events were common during critically ill children transport. Immediate orotracheal intubation at admission was frequent; therefore, lack of respiratory failure anticipation was common. Absence of communication between hospitals and PICU staff was the rule. Lack of training in paediatric transport is an urgent issue to address in Colombia.
