Others
NO
Association between physician volume and death rate in patients who are hospitalized for ischemic and haemorrhagic stroke remains unclear. It is unknown whether a volume threshold for such an association exists. We aimed to analyse the correlation between in-hospital stroke mortality and physician volume, considering board certification status.

Male and Female
We identified patients hospitalized for stroke in a deidentified discharge database using the International Classification of Diseases (ICD)10 diagnosis codes related to ischemic stroke (I63 0to9), nontraumatic intracerebral haemorrhage (ICH I61 0 to9) and subarachnoid haemorrhage (SAH I60 0to9). Because of major differences in their typical prognosis, patients with transient ischemic attack were excluded. We further selected those patients who had been urgently admitted between 1 April 2010 and 31 March 2016 to the hospitals.

From 295,150 (ischemic stroke), 98,657 (ICH), and 36,174 (SAH) patients, 30day inhospital mortality rates were 4, 16, and 26%. For all stroke types, the number of stroke care physicians was associated with reduced in-hospital mortality (all p for trend<0.001). The numbers of board-certified neurosurgeons, stroke physicians, and endovascular surgeons showed clear association with reduced in-hospital mortality for ischemic stroke
