Evaluation of pre-hospital transport time of stroke patients to thrombolytic treatment.

Bottom Line: Response time was reduced from the period before to the period after reorganization (7 vs. 5 minutes, p <0.001).In a linear multiple regression model, higher patient age and longer distance to the hospital correlated with significantly longer transportation time (p <0.001).Response time, but not total alarm-to-door time, was reduced during the five years.

ABSTRACT

Background: Effective treatment of stroke is time dependent. Pre-hospital management is an important link in reducing the time from occurrence of stroke symptoms to effective treatment. The aim of this study was to evaluate time used by emergency medical services (EMS) for stroke patients during a five-year period in order to identify potential delays and evaluate the reorganization of EMS in Copenhagen in 2009.

Methods: We performed a retrospective analysis of ambulance records from stroke patients suitable for thrombolysis from 1 January 2006 to 7 July 2011. We noted response time from dispatch of the ambulance to arrival at the scene, on-scene time and transport time to the hospital-in total, alarm-to-door time. In addition, we noted baseline characteristics.

Results: We reviewed 481 records (58% male, median age 66 years). The median (IQR) alarm-to-door time in minutes was 41 (33-52), of which 18 (12-24) minutes were spent on scene. Response time was reduced from the period before to the period after reorganization (7 vs. 5 minutes, p <0.001). In a linear multiple regression model, higher patient age and longer distance to the hospital correlated with significantly longer transportation time (p <0.001).

Conclusions: This study shows an unchanged alarm-to-door time of 41 minutes over a five-year period. Response time, but not total alarm-to-door time, was reduced during the five years. On-scene time constituted nearly half of the total alarm-to-door time and is thus a point of focus for improvement.

Mentions: The median age was 66 years (IQR 55–76 years), and 58% of patients were men. The age distribution was not normally distributed and is summarized in Figure 1. Seventy-seven percent of patients received thrombolytic treatment. Number of transports for the duration of the study period was not normally distributed and is illustrated in Figure 2.Figure 1
