Los Angeles Prehospital Stroke Screen GudangMovies21 Rebahinxxi LK21

    The Los Angeles Prehospital Stroke Screen (abbreviated LAPSS) is a method of identifying potential stroke patients in a pre-hospital setting.


    Screening criteria


    No history of seizures or epilepsy
    Age 45 years or older
    At baseline, patient is not bedridden and does not use a wheelchair
    Blood glucose between 60 and 400 mg/dL
    Obvious asymmetry-unilateral weakness with any of the following motor exams:
    Facial Smile/Grimace
    Grip
    Arm Strength
    If all of the above criteria are met (or not ascertainable) the LAPSS is positive for stroke. Patients may still be experiencing a stroke even if LAPSS criteria are not met.


    Validity


    A January 2000 study, conducted by 3 teams of Los Angeles-based paramedic units resulted in "sensitivity of 91% (95% CI, 76% to 98%), specificity of 97% (95% CI, 93% to 99%), positive predictive value of 86% (95% CI, 70% to 95%), and negative predictive value of 98% (95% CI, 95% to 99%). With correction for the 4 documentation errors, positive predictive value increased to 97% (95% CI, 84% to 99%)."
    In a Chinese study, Beijing paramedics using the protocol, completed LAPSS screenings in an average of 4.3±3.0 minutes (median, 5 minutes). The study resulted in a sensitivity of 78.44% and a specificity of 90.22%.
