BACKGROUND: Helicopter transport may shorten transport time to neurosurgical intervention; however, there is little data regarding its utility for non-traumatic emergencies. METHODS: Pre-hospital and hospital records of all @entity1 transferred via helicopter to Dartmouth-Hitchcock Medical Center for spontaneous @entity510 between January 2007- December 2011 were reviewed. Primary outcome measure was emergent tertiary-level care intervention, defined as ventriculostomy, conventional angiography, endovascular treatment, or craniotomy within three hours of arrival. RESULTS: Fifty-one @entity1 met inclusion criteria. Median helicopter transport time, defined as time from telephone referral to arrival, was 97 minutes (range 61-214 minutes). Fifteen @entity1 underwent intervention within 3 hours of arrival (29%), 19 between 3 and 6 hours (37%), 9 between 6 to 12 hours (18%), and 11 greater than 12 hours after arrival (16%). Univariate analysis of pre-transfer clinical and radiographic findings showed significant correlations between GCS less than 15 (OR 22.8, 95%CI 4.2-122.5), WFNS scale greater than 2 (OR 46.75, 95%CI 7.511-290.99), presence of @entity548 (OR 4.7, 95%CI 1.3-17.5), and intubation (OR 12.4, 95%CI 2.9-51.8) with emergent intervention. On logistic multivariate regression analysis, GCS less than 15 and WFNS scale greater than 2 independently predicted emergent intervention. CONCLUSIONS: A majority of @entity1 with spontaneous @entity510 who were transferred by inter-facility helicopter ambulance did not require emergent intervention. GCS less than 15 at an outside hospital was independently associated with emergent intervention on multivariate analysis.
