Onset-to-alarm time in patients with acute stroke: Results from a Mexican population

Abstract: Dear Editor, Reperfusion therapy using tissue plasminogen activator (tPA) improves the clinical outcome in stroke; however, it should be applied during the first 4.5 h. Only less than 30% of patients arrive at the hospital on time mainly due to a prehospital delay. 1,2 Prehospital delay is analyzed as onset-to-door time, which is divided into onset-to-alarm time (OAT), that corresponds to the time since the patient or the witness identified stroke symptoms until the decision to look for medical attention, and … Show more

“…We identified 67 studies addressing pre-hospital organizational factors associated with delay or access to ART ( Appendix A - Table A3 ). Activation of stroke code, pre-hospital notification and use of pre-hospital emergency services [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ], mobile stroke units [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ], implementation of specific electronic apps to insert and share clinical data with the hospital stuff [ 33 ], use of ambulance [ 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ], telestroke [ 47 , 48 ], implementation of specific pre-hospital protocols [ 49 , 50 ], education campaigns […”

“…On the other hand, existing comorbidities, such as stroke history and related risk factors (e.g., hypertension, atrial fibrillation) play an important role in earlier response ( 7 , 10 13 ). Consequently, it is not just the knowledge of stroke symptoms that prompt timely hospital arrival but also the response to symptoms ( 12 , 14 ). It is thus crucial that people correctly identify symptoms pointing toward a stroke that they or their loved ones encounter ( 15 ).…”

“…The ability to act quickly and obtain the most appropriate treatment is crucial to a favourable outcome of stroke (Gonzalez-Aquines et al, 2018). Studies have noted that speedy action reduces emergency medical system response times and optimises in-hospital response times which may lead to an increase in thrombolysis rates to 57% (California Acute Stroke Pilot Registry [CASPR] Investigators, 2005).…”
