Drug resistance from treatment-related causes is often the result of misuse (e.g.,incorrect use,overuse,or underuse)of antibiotics.It is believed that 50% of all antibiotic use in the United States can be characterized by misuse in one form or another,and efforts to reduce surgical site infections include appropriate prophylactic antibiotic use in surgical patients.It is estimated that half of all antibiotic prescriptions written are not warranted.Although some surgical complications are unavoidable,surgical care can be improved through decisions and subsequent care focusing on evidence-based practice recommendations.Research shows that delivering antibiotics to a patient within 1 hour of beginning surgery (or 2 hours for vancomycin or fluorquinolones which need to be administered over 1 to 2 hours)can dramatically decrease SSI rates,yet this practice is not followed in all situations.
