Effect of teleconsultation on the application of thrombolytic therapy in stroke patients in the emergency department

Introduction Recently, telemedicine has become a widely used method worldwide for the treatment of patients with acute ischemic stroke in hospitals where neurologists are unavailable. The purpose of this study was to determine the accuracy and reliability of treatment decisions made by remote neurologists via teleconference assisted by emergency physicians in acute stroke cases and to determine whether the use of teleconsultation would lead to any delays in assessment and treatment decisions. Methods This single-center and prospective study was performed with 104 patients who met the inclusion criteria. Patients were concurrently assessed by a teleneurologist (TN) experienced in stroke and an on-site neurologist (OS-N). The TN performed their assessment via teleconference and assisted by an emergency physician for test results and physical examination. NIHSS (The National Institutes of Health Stroke Scale) scores, assessment times, treatment decisions by the two neurologists, and patient outcomes were recorded separately. The TN was asked to rate the quality of communication. Results Of the 104 patients in the study, 59.6% (n = 62) were men and the median age was 66 (interquartile range = 56–78) years. The median duration of assessment by the OS-N was 30 (18–45) min and the median duration of assessment by the TN was 6 (5–8) min; the duration of assessment by the TN was significantly shorter (6.56 min vs. 33.35 min; Z = 8.669; p < 0.001 ). The median rating assigned by the TN to the quality of teleconsultation was 5.0 (4.25–5.0) (Table 1 ). The NIHSS scores assigned by both neurologists showed significant correlation (p < 0.001 ). Analysis of the agreement between the OS-N and TN in their treatment decisions yielded a Kappa value of 74.3% for interrater agreement. Conclusions Teleconsultation was a successful and reliable strategy in assessing patients with ischemic stroke and making decisions for IV-tPA. Moreover, patient assessment via teleconsultation was less time consuming. The results of the study are promising for the use of teleconsultation in the future.
