Antibiotic prophylaxis audit and questionnaire study: Traffic Light Poster improves adherence to protocol in gastrointestinal surgery

Abstract

ObjectiveTo measure adherence to antibiotic prophylaxis (AP) protocol amongst surgeons and anesthetists and explore their understanding of AP prescribing in practice. DesignA prospective audit of AP in gastrointestinal surgery and re-audit after intervention. A questionnaire survey of practice. Results58 (38%- clean; 62%- clean contaminated) operations were audited and 73 (48%-clean; 51%-clean contaminated) operations were re-audited after intervention with “Traffic Light Poster” (TFP) .55 colleagues (32 consultants and 23 trainees) were recruited for questionnaire survey in three West Midlands hospitals.Audit and Re-Audits. Only 31% of procedures followed the protocol correctly in the initial audit and this increased to 73% in the re-audit. 73% of patients undergoing clean procedures received AP inappropriately in the initial audit but reduced significantly to 20% (p < 0.002) in the re-audit. In the initial audit, 62% of clean contaminated procedures did not receive the appropriate first line AP but this fell to 35% (p < 0.05) in the re-audit.Questionnaire Survey- Only 30% of respondents would not give AP in clean surgery as recommended. 45% would use appropriate AP for clean-contaminated wounds. 73% of respondents will give AP at induction, 20% 1 h pre op and 7% just before incision. ConclusionThere is poor compliance with AP protocols in gastrointestinal surgery in part due to general lack of awareness. An educational intervention in the form of a ‘Traffic Light Poster’ improved adherence to AP protocol two fold. There was improved rationalizing of AP. Clean procedures, in particular, had less inappropriate prescribing.
