Which prehospital stroke screen has a 97 percent accuracy in identifying actual stroke patients?

The correct answer is based on the fact that the Los Angeles Prehospital Stroke Screen (LAPSS) is specifically designed to assess patients for possible strokes in a prehospital setting. It includes criteria such as age, history of seizures, duration of symptoms, and specific neurological deficits, all of which have been validated to provide a high degree of accuracy in identifying actual stroke patients.

The LAPSS has been well-studied and documented to have approximately 97% accuracy in correctly identifying those who are experiencing a stroke, making it a reliable tool for emergency medical personnel when assessing patients who may require urgent interventions, such as thrombolysis. By using this screening tool, EMTs can ensure that patients who are indeed having a stroke receive timely transport to appropriate medical facilities for further evaluation and treatment.

Other prehospital stroke assessments, while useful, do not have the same level of documented accuracy as the LAPSS. Each of these alternative tools might serve specific purposes or have broader applications, but the LAPSS stands out for its precision in this particular context.
