| Popis: | Introduction: The timing of administering tissue-type plasminogen activator (tPA) in patients with an ischemic stroke is directly related to clinical outcomes. The use of a mobile stroke unit (MSU) is a strategy to provide acute ischemic stroke assessment and treatment in a more rapid fashion compared to standard stroke transport and management. Our program initiated the use of a MSU in 2017 as a part of a phased implementation program. We sought to determine the impact of the MSU on the timing of stroke care in the region as it related to proximity to the hospital. Methods: We collected data during the first 9 months of 2017 on patients who were transported to the hospital as pre-hospital stroke alerts (PHSA) via conventional ambulance or via the MSU. Using a retrospective case-controlled design we compared process metrics associated with the phased implementation of the MSU with conventional pre-hospital stroke alerts as standard of care (SOC). Results: There was a total of 178 stroke alert patients; 72 in the MSU group and 106 in the PHSA group. 35 patients received tPA, 16 in the MSU, 19 in SOC. There was no significant difference in age, body weight, race, gender, and length of stay in the hospital in the two groups. The time from 911 call to arrival on scene was 12.06 min versus 20.4 min in the PHSA and MSU groups, respectively. Despite a longer time for arrival TPA administration for patients within a 5 miles radius of the hospital was 89 ± 25 mins in the SOC group and 78±12 mins in the MSU group (p=0.11). For 911 calls originating 10-20 miles from the hospital, the time for 911 call to tPA was 106 ± 23 mins in the PHSA group (n = 4) and 86 ± 2 mins in the MSU group (n = 4). Conclusion: Our initial results are comparable with previously reported data . Our data suggests the MSU may have a greater impact on reducing time to tPA for those further from the hospital or where transport time is delayed. The role of the MSU for non tPA patients such as mechanical thrombectomy, intracerebral hemorrhage and subarachnoid hemorrhage warrants further investigation. |
