Intervention effect and appraisal cognition behavior of about rational antibiotic usage among general surgeons.

OBJECTIVE To explore the pathway of effective intervention to increase among clinicians the cognition knowledge level about rational use of antibiotics.METHODS The cognition about antibiotics knowledge through intervention among general surgeons in our hospital was investigated by cluster sampling.RESULTS The ratio of prescription by China Approved Drug Names increased from 57.7% before intervention to 94.0% after intervention(P0.05).Before intervention only 4 surgeons used antibiotics less than 30% of surgical patients vs 10 surgeons after intervention and 6 vs 10 surgeons(30-50% of surgical patients).The surgeons who used antibiotics less than 3d increased from 12.5% beforeintervention to 40.6% after intervention(P0.05).The first three factors influencing the surgeons to choose the antibiotics were efficacy,pathogens and safety,but after intervention more surgeons began to pay attention to drug resistance of bacteria.Surgeons'self-evaluation on knowledge of antibiotics was all good both before and after intervention.But the survey results showed that surgeons grasped general knowledge well,but cognized professional knowledge poor.By quantitative evaluation on surgeon professional knowledge,the average score was only(3.91±1.12)vs(6.06±1.27),after intervention.CONCLUSIONS The antibiotics knowledge of surgeons has gained some improvement by intervention,but grows slowly in general,it needs further strengthen the integrated management,communication and training.
