title: Which should be the essential components of stroke centers in Japan? A survey by questionnaires sent to the directors of facilities certified by the Japan stroke society.
abstract: BACKGROUND
  We conducted a survey by questionnaire to identify the essential components of stroke centers in Japan and compared our results with the European Expert Survey.
  
  
  METHODS
  In 2007, a questionnaire was mailed to the directors of 740 facilities certified by the Japan Stroke Society to ask their opinion on the essential components of comprehensive stroke centers (CSC), primary stroke centers (PSC) and any hospital ward (AHW) admitting acute stroke patients. The directors were asked to provide 1 of the following 6 possible answers regarding 112 components: 'irrelevant'; 'useful but not necessary'; 'desirable'; 'important but not absolutely necessary'; 'absolutely necessary', or 'question unclear or ambiguous'. The components considered 'absolutely necessary' by more than 75% of the respondents were compared between our survey and the European Expert Survey. In addition, we compared the rates of neurosurgeons and neurologists who answered 'absolutely necessary' with regard to each component.
  
  
  RESULTS
  Responses were obtained from 428 directors (57.8% response rate). Among these respondents, 298 (69.6%) were neurosurgeons. There was no component considered 'absolutely necessary' for AHW by more than 75% of the respondents, and this was similar to the results of the European Expert Survey. The following components were considered 'absolutely necessary' for PSC in our survey: brain CT scanning 24 h a day, 7 days a week (24/7); automated monitoring of the ECG, pulse oximetry, blood pressure and breathing, and respiratory support. In both our survey and the European Expert Survey, the essential components for CSC were as follows: physiotherapist; brain CT scanning 24/7; monitoring of the ECG, pulse oximetry and blood pressure; carotid surgery; angioplasty and stenting, and intravenous recombinant tissue plasminogen activator protocols. The components multidisciplinary stroke team, stroke-trained nurse, ultrasonography, collaboration with an outside rehabilitation center, stroke pathway and clinical research were deemed essential only in the European Expert Survey. However, MRI 24/7, MR angiography 24/7, conventional angiography 24/7, respiratory support as well as most neuroendovascular and neurosurgical treatments were considered necessary for CSC by more than 75% of the respondents in our survey. Analyzing the responses from only neurologists reduced the differences between our survey and the European Expert Survey.
  
  
  CONCLUSIONS
  The present study indicated the essential components expected for stroke centers in Japan. Our survey demonstrated that more emphasis was likely to be placed on installations than on a dedicated stroke team and the use of stroke care maps. In addition, the results of this study may reflect some characteristics of the stroke care environment in Japan, such as the predominance of neurosurgeons and widespread use of MRI.
