Methods: A prospective survey of dressings used to cover abdominal wounds was undertaken. Surgical trainees from 25 hospitals were invited to participate. Information about patient risk factors, operation type and type of wound dressings used were recorded for elective and unplanned abdominal procedures over a two week period. The type of dressings used were summarized and associations with operation type and patient risk factors explored.
Results: Twenty hospitals participated, providing data from 727 patients (1794 wounds). Wounds were predominantly covered with basic dressings (n=1203/1769, 68%) and in 27% (485/1769), tissue adhesive was used; dressing type was missing for 25 wounds. Just 4% (63/1769) wounds did not have a dressing applied at the end of the procedure. There was no evidence of an association between type of dressing used and patient risk factors, type of operation, or between elective and unscheduled surgery.
Conclusions: Based on the findings from this large study of current practice, the pilot study design has evolved. The inclusion criteria have expanded to encompass patients undergoing unscheduled surgery, and tissue adhesive as-a-dressing will be evaluated as an additional intervention group. Collaborative methods are recommended to inform the design of RCTs in surgery, helping to ensure they are relevant to current practice.
