Emergency and Urgent Care Network: Analysis of the Stroke Care Line According to Care Times and Outcomes

Background: Given the importance of acute stroke care for public health in terms of its burden and consequences like disability and death, evidence-based practice has directed the development of clinical protocols and operational guidelines to care of the populations affected by this pathology.

Aim: To evaluate the impact of implementing the stroke care line in the Urgency and Emergency Care Network of a large Brazilian municipality.

Methods: This is a retrospective study, conducted between 2014 and 2019 in public health services in Ribeirao Preto, SP, a large municipality of Brazil. Data was collected through secondary sources. A total of 403 patients were included in the study, of which: 172 were treated between 2014 and 2016 and 231 between 2017 and 2019; 118 were served by the mobile pre-hospital care services and 285 by the fixed pre-hospital care services. Data comprise clinical, epidemiological characteristics and severity of cases, as well as stroke care times and outcomes and were analyzed using descriptive techniques, Mann-Whitney and Chi-squared tests.

Results: First care provided by a mobile pre-hospital care unit increased from 16.9% to 38.5%. The service times for people undergoing thrombolysis were shorter in the period from 2017 to 2019 compared to 2014 to 2016 in the door-to-needle, stroke onset-to-call, stroke onset-to-ambulance dispatch and regulation-to-door times. Stroke victims treated first by a mobile (ambulance) unit had shorter care times when compared to those who received care in a fixed unit, except in ambulance dispatch-to-door time. No difference was identified in the percentage of outcomes studied in the period from 2017 to 2019 compared to the period from 2014 to 2016. There was a higher craniectomy occurrence in people treated at home than in those attended in health services. The percentage of unfavorable stroke outcomes increased depending on the case severity.

Conclusion: The care flow organization with defined responsibilities for each care point through the creation of a care line and the use of pre-established protocols reduced pre- and in-hospital care times; however, they did not have a significative influence on the case outcomes.
