One change to field triage guidelines for emergency medical services (EMS) responding to older adults with head trauma could make a ‘clinically important improvement over usual care,’ according to a study and accompanying editorial published earlier this month.
‘Adding a question about the use of blood thinners in older adults to our field triage criteria could save lives,’ said the editorial’s writer, Craig Newgard, MD, MPH, of Oregon Health & Science University in Portland, Ore. ‘Older patients suffering head trauma who are taking blood thinners are more likely to suffer from bleeding in the brain that requires time-sensitive surgery at a major trauma centre. Current EMS triage criteria do not include that question but this study suggests that maybe they should.’
Researchers analysed charts for 2,100 patients who were 55 or older with head trauma who were transported to the hospital by EMS. Using standard field triage criteria, 19.8 percent of those patients were correctly identified as suffering traumatic intracranial haemorrhage, or bleeding in the brain. Adding a fourth question – whether the patient is on anti-coagulant therapy – improved the sensitivity for intracranial haemorrhage to 59.5 percent.
‘Use of steps one to three triage criteria is not sufficient for identifying intracranial haemorrhage and death or neurosurgery for older patients who suffer head trauma,’ said the lead author of the study, Daniel K. Nishijima, MD, MAS, of the University of California Davis School of Medicine in Sacramento, Calif. ‘While we wait for other studies to confirm our research, we strongly urge patients to make their medication history available and known to their families and EMS providers, especially for situations that may arise where they cannot speak for themselves. Knowledge of their use of blood thinners may help in getting these patients to the right hospital.’
