title: Classifying complications of interventional procedures: a survey of practicing radiologists.
abstract: OBJECTIVE
  To determine the variability of radiologists' classification of complications from interventional procedures.
  
  
  METHODS
  Fifteen test cases were selected from a database of morbidity and mortality cases that occurred in our department during the past 2 years. Ten cases were selected randomly, and five were chosen because of classification difficulties within our department. A survey with the case descriptions was presented to 145 SCVIR members via the World Wide Web and 48 were distributed to participants at a statewide angiography club meeting. Participants were asked to complete a short assessment of the their clinical background and to classify each case as "no complication," "minor complication," or "major complication."
  
  
  RESULTS
  Thirty-eight percent (74 of 193) of the surveys were completed. Seventy percent (52 of 74) of the respondents were affiliated with an academic program, 12% (nine of 74) were affiliated with private practice groups, and 18% (13 of 74) claimed both academic and private affiliation. The consensus rate in classifying the complications for the randomly selected cases varied from 50% to 95%, with a median of 69%, and the consensus rate in classifying the selected cases varied from 46% to 95%, with a median of 85%. The lowest consensus rates occurred when (i) a significant procedural event was followed by a normal outcome, (ii) when a procedure was aborted, and (iii) when a significant event occurred but did not prolong hospital stay.
  
  
  CONCLUSIONS
  Current criteria for reporting complications are associated with moderate rates of disagreement among interventional radiologists.
