title: Digital chromoendoscopy utilization in clinical practice: A survey of gastroenterologists in Connecticut.
abstract: OBJECTIVE
  To use a survey to characterize and identify potential barriers to the use of digital chromoendoscopy (DC) by practicing gastroenterologists.
  
  
  METHODS
  An anonymous, internet-based survey was sent to gastroenterologists in Connecticut who were members of one of three national gastrointestinal organizations. The survey collected demographic information, frequency of DC use, types of procedures that the respondent performs, setting of practice (academic vs community), years out of training, amount of training in DC, desire to have DC training and perceived barriers to DC use. Responses were collected anonymously. The primary endpoint was the proportion of endoscopists utilizing DC. Associations between the various data collected were analyzed using χ(2) test.
  
  
  RESULTS
  One hundred and twenty-four gastroenterologists (48%) of 261 who received the online survey responded. Seventy-eight percent of surveyed gastroenterologists have used DC during the performance of upper endoscopy and 81% with lower endoscopy. DC was used in more than half of procedures by only 14% of gastroenterologists during upper endoscopy and 12% during lower endoscopy. Twenty-three percent (upper) and 21% (lower) used DC more than one quarter of the time. DC was used for 10% or less of endoscopies by 60% (upper) and 53% (lower) of respondents. Endoscopists reported lack of training as the leading deterrent to DC use with 36% reporting it as their primary deterrent. Eighty-nine percent of endoscopists never received formal training in DC. Lack of time (30% of respondents), lack of evidence (24%) and lack of reimbursement (10%) were additional deterrents. There were no differences in DC use relative to academic vs community practice setting or years out of training.
  
  
  CONCLUSIONS
  DC is used infrequently by most endoscopists, primarily due to a lack of training. Training opportunities should be expanded to meet the interest expressed by the majority of endoscopists.
