“…In adult cardiac arrest, physician presence during resuscitation, compared with paramedics alone, has been reported to increase compliance with guidelines (LOE 2 307 ; LOE 4 308 ) and physicians in some systems can perform advanced resuscitation procedures more successfully (LOE 2 307,309 ; LOE 4 310 -312 ). When compared within individual systems, 4 studies suggested improved survival to hospital discharge when physicians were part of the resuscitation team (LOE 2 313,314 ; LOE 3 315,316 ) and 10 studies suggested no difference in survival of the event (LOE 2) 307,313 or survival to hospital discharge (LOE 2).…”
