  20. 25. IMPROVED RESPONSE TIMES WITH MOTORCYCLE BASED FAST RESPONSE PARAMEDICS IN AN URBAN SETTINGS Ong Marcus, MBBS, FRCS Ed (A&E) Registrar, Department of Emergency Medicine, Singapore General Hospital Chan YH, Phd Head Biostatistics, Clinical Trials and Epidemiology Research Unit, Ministry of Health A/P V Anatharaman, MBBS, MRCP, FRCS Ed (A&E), FAMS Senior Consultant and Head, Department of Emergency Medicine, SGH Clinical Associate Professor, Faculty of Medicine, NUS introduction aims/objectives methods results conclusions Pre-hospital response intervals are known to be an important factor in the level of care provided by any Emergency Medical System. In big cities, response intervals are known to be long due to traffic and accessibility problems. To see if response intervals can be improved with motorcycle based Fast Response Paramedics (FRP) compared with standard ambulances in an urban setting. A prospective, observational study. Simultaneous dispatch of motorcycles based FRP’s equipped with Automated External Defibrillators and standard ambulances for cardiac arrest, cardiac, respiratory conditions and road traffic accidents. 48 consecutive ambulance runs were recorded. Locations involved: home (41.7%), work (29.2%), road accident (20.8%) and others (8.3%) Ambulances took on average 4.96 minutes longer than motorcycles to respond (p<0.001, 95% CI 2.61 to 7.31). Adjusting (via multiple regression) for the day of the week, location, station, traffic and case, ambulances took on the average 4.71 (p<0.001, 95% CI 2.45 to 6.98) minutes longer to respond. Improvements in response times were greater when overall response times were longer (weekdays, residential/office location, moderate or heavy traffic). Use of motorcycle based paramedics allow for faster response intervals and earlier interventions, especially early defibrillation in cardiac arrest. Larger follow-up studies are planned to assess the impact of implementation of more FRP’s on mortality and morbidity.
