Summary
This indicator is intended to identify trauma systems with protocols for guiding transfer of injured patients between healthcare facilities.


Panel Review
Panelists emphasized the importance of this indicator for rural regions where Level 1 centers are significant distances from the site of injury. It was noted that there is a need to evaluate both the application and effectiveness of the protocol in addition to simply having a protocol. Panelists reported that protocols may vary between centers and this could impact protocol effectiveness.


Trauma Center Review
The trauma centers emphasized the importance of protocols for both patient transfer and transfer agreements between centers. They noted that getting the patient to the most appropriate facility is important. The trauma centers highlighted that all centers, regardless of trauma center status, needed to be involved in documentation for this indicator.


Review of Literature & Evidence
Face Validity: In one study, 88% of Delphi panel participants ranked implementation of a protocol to ensure prompt transfer of trauma patients from a lower-level to a higher-level facility as very important13.
Construct Validity: No studies identified.
Reliability: No studies identified.
Risk Adjustment: Not applicable.
Utilization: Patient Transfer Protocol is used as an indicator by a moderate number of trauma centers: USA 38% (75/200), Canada 3% (1/35), Australasia 0% (0/12).
Protocols should specify the transfer of appropriate injured patients from rural areas to Level 1 trauma centers in a timely fashion in order to reduce mortality rates30. Two hours has been suggested as one possible time threshold for transfer31. There is some evidence to support the use of helicopter transfer to improve patient survival32. Pretransfer interventions such as CT scan and laparotomy have been shown to delay time of transportation and increase cost and not improve outcomes33. Protocols should include means to ensure the equitable transfer of patients and not be based on patients’ ability to pay34.
