title: [Complications and monitoring standards after elective craniotomy in Germany].
abstract: BACKGROUND
  The increasing endeavors to make inpatient treatment processes more effective leads to a reduction of the length of stay in hospital and minimization of postoperative monitoring. Therefore, the aim of our study was to determine potential postoperative complications for neurosurgical patients undergoing elective surgery with respect to assessment of the relevance for intensive medical care. Furthermore, our approach was compared with the standard of postoperative care of such patients in Germany.
  
  
  METHODS
  All 499 patients scheduled for elective craniotomy at our institute from 2010-2013 could be included corresponding to various treatment criteria for vascular diseases, such as aneurysms, arteriovenous malformation (AVM) and cavernous hemangioma as well as supratentorial and infratentorial tumors, transsphenoidally operated pituitary adenomas and stereotactic biopsies. All complications could be collated and categorized according to major and minor complications. Furthermore, a survey was conducted among 155 neurosurgical hospitals and departments with respect to the preferred postoperative monitoring strategy for the named treatment categories.
  
  
  RESULTS
  The numbers of major complication were in accordance with data from other studies and although minor complications (13.4% in our collective) are rarely recorded in the literature, they do however indicate an adequate postoperative inpatient monitoring. The results of the survey showed a broad preference for intensive care unit monitoring of patients undergoing elective craniotomy in Germany.
  
  
  CONCLUSIONS
  The undisputed gold standard of postoperative monitoring of neurosurgical patients undergoing elective surgery is still the intensive care unit. Although more flexible surveillance modalities are available, a cost-driven restructuring of postoperative monitoring and in particular reduction of the length of stay in hospital must be subjected to detailed scrutinization.
