Spinal Immobilization in Disasters: A Systematic Review

In response to the International Liaison Committee on Resuscitation (ILCOR; Niel, Belgium) release of an updated recommendation related to out-of-hospital spinal immobilization (SI) practice in 2015, a systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist of English-language studies published from January 2000 through July 2019 on the use of SI in resource-scarce environments (RSEs). Studies meeting the following criteria were included in the analysis: peer-reviewed statistical studies or reports detailing management of potential traumatic spinal injury in RSE, civilian, and military environments; as well as consensus clinical guidelines, academic center, or professional association protocols or policy statements detailing management of potential traumatic spinal injury in RSE, civilian, and military environments; statistical analysis; and subsequent management of spinal injuries after mass-casualty incidents, in complex humanitarian events or conflict zones, low-to middle-income countries, or prolonged transport times published by government and non-government organizations. Studies excluded from consideration were those not related to a patient with a potential traumatic spinal injury after a mass-casualty incident, in complex humanitarian event or conflict zones, in low-to middle-income countries, or with prolonged transport times.There were one thousand twenty-nine (1029) studies initially identified. After removal of duplicates, nine hundred-nineteen (919) were screened with eight hundred sixty-three (863) excluded. The remaining fifty-six (56) received further review with fourteen (14) selected studies achieving inclusion. The reviewed articles comprised six (6) types of studies and represented research from institutions in seven (7) different countries (Israel, United States, Haiti, Wales, Pakistan, China, and Iran). Thirteen (13) references were case reports/narrative reviews, policy statements, retrospective observational studies, narrative literature reviews, scoping reviews, and one systematic review. The majority of literature describing spinal cord injury was predominantly associated with earthquakes and blast-related disasters. There were no SI evidence-based clinical guidelines (EBG) in RSE. Information was obtained that could be used to formulate statements in a modified Delphi study to present to experts to obtain consensus SI EBG in RSE.
