title: Management of patients with colorectal cancer: do Australian surgeons know the scientific evidence?
abstract: OBJECTIVE
  Not all Australian surgeons are aware of the status of the current evidence for the management of colorectal cancer.
  
  
  METHODS
  Postal survey of Fellows of the Royal Australasian College of Surgeons.
  
  
  METHODS
  One hundred ninety-five surgeons (127 general surgeons and 68 subspecialist colorectal surgeons) from a response fraction of 89%.
  
  
  METHODS
  Overall awareness score for 23 clinical recommendations and a subscore for 10 of these for which evidence is compelling rather than inconclusive (9 for and 1 against incorporation in clinical practice).
  
  
  RESULTS
  Although no surgeon indicated the status of the evidence correctly for all 23 items, 61% of respondents correctly identified 12 or more items. Surgeons who practiced in capital cities had significantly higher scores than those who practiced outside cities (beta =.16; B = 1.01; 95% confidence interval [CI], 0.14-1.89; P =.02). Surgeons who had been in practice for relatively more years had significantly lower scores than younger surgeons (beta = -.17; B = -0.059; 95% CI, -0.11 to 0.01; P =.02). Surgeons involved in research had significantly higher scores (beta =.18; B = 1.11; 95% CI, 0.23-1.99; P =.01), as did those respondents who had been involved in guideline development (beta =.18; B = 1.42; 95% CI, 0.24-2.63; P =.02). Subscores showed a significantly greater awareness of compelling evidence (level I or level II) (P<.001). There was no relationship between awareness of the evidence for adjuvant therapy and surgeons' perceptions of the usefulness of guidelines about this aspect of clinical management.
  
  
  CONCLUSIONS
  Our innovative preguidelines survey has shown that not all surgeons were aware of the evidence underpinning the management of colorectal cancer, affirming the need for guidelines. Predictors of low awareness could be used to target efforts to disseminate and implement guidelines.
