Association between physician-staffed ambulances and patient prognoses after out-of-hospital cardiac arrests with respect to shockable and non-shockable rhythms: a retrospective observational study in a southern area of Shiga Prefecture Japan.

Despite our study's limitations, physician-staffed ambulances might be associated with good neurological outcomes in non-shockable rhythm patients. Our observations could provide more appropriate prehospital treatment options for OHCA patients.
