title: Informed consent in direct access colonoscopy.
abstract: OBJECTIVE
  Although direct access colonoscopy is a common practice, some consider the level of informed consent as inadequate, and therefore a medico-legal concern. The aim of this study was to assess the adequacy of informed consent from a patient perspective in a direct access colonoscopy service.
  
  
  METHODS
  All patients having outpatient colonoscopy from May 2003 to February 2004 at a direct access colonoscopy service were considered for inclusion into the study. Information was obtained from patients by structured questionnaire administered either at the time of discharge from the day ward or mailed to their homes.
  
  
  RESULTS
  Information was obtained from 346 direct access colonoscopy patients (172 male, 159 female; 226 >or= 50 years, 103 < 50 years), 80% of whom were referred by their family doctor. Colonoscopy was done for investigation of symptoms in 220 patients, and for screening and surveillance in 115 patients, with an indication not specified in 11 patients. The majority of patients were either very satisfied (70.5%) or satisfied (25.1%) with the consent process, with no demographic characteristics found to predict dissatisfaction. Thirty-seven patients expressed a preference to have seen a gastroenterologist prior to colonoscopy, and four of these patients reported the consent process to be unsatisfactory. Seventy (20.2%) patients reported that the most useful information about colonoscopy was received after they had completed bowel preparation.
  
  
  CONCLUSIONS
  No demographic characteristics were found to predict the small fraction of patients dissatisfied with the informed consent process. Further medico-legal risk reduction may be facilitated by enhancing the provision of information prior to bowel preparation.
