Oklahoma Foundation for Medical Quality Performance Improvement for the Surgeon: SIPP and SCPP Why SIPP?

Oklahoma Foundation for Medical Quality Public Health Importance n SSI occurs in 2-5% of extra abdominal surgeries and up to 20% of intra-abdominal surgeries n SSI patients are 60% more likely to spend time in the ICU 5x more likely to be re-admitted 2x the incidence of mortality

Surgical Procedures of Interest National Surgical Infection Prevention Project n Cardiac n Coronary Artery Bypass Graft (CABG) n Colon n Hip & Knee Arthroplasty n Hysterectomy (abdominal and vaginal) n Vascular Surgery: Aneurysm repair Thromboendarterectomy Vein Bypass These procedures are being evaluated in the Medicare project because there is no controversy over the use of antibiotics for these operations. This does not imply that antibiotic prophylaxis should not be used for other procedures.

Oklahoma Foundation for Medical Quality Quality Indicators Quality Indicators National Surgical Infection Prevention Project n Quality Indicator #1 Proportion of patients who receive antibiotics within 1 hour before surgical incision Because of the longer required infusion time, vancomycin, when indicated for beta-lactam allergy, may be started within 2 hours before the incision.

Oklahoma Foundation for Medical Quality Impact of Timing of Antibiotic Prophylaxis Classen DC, et al. N Engl J Med

Oklahoma Foundation for Medical Quality Dose of Antibiotic for Prophylaxis n Always give at least a full therapeutic dose of antibiotic n Consider the upper range of doses for large patients and/or long operations n Consider repeating doses for long operations

Oklahoma Foundation for Medical Quality Quality Indicators Quality Indicators National Surgical Infection Prevention Project n Quality Indicator #2 Proportion of patients who receive prophylactic antibiotics consistent with current recommendations

Oklahoma Foundation for Medical Quality Appropriate Antibiotics Appropriate Antibiotics National Surgical Infection Prevention Project n Cardiac and vascular surgery cefazolin, cefuroxime, cefamandole (vancomycin only if documented beta- lactam allergy) n Hip and knee arthroplasty cefazolin, cefuroxime (vancomycin only if documented beta- lactam allergy)

Oklahoma Foundation for Medical Quality Appropriate Antibiotics Appropriate Antibiotics National Surgical Infection Prevention Project n Hysterectomy cefazolin, cefotetan, cefoxitin, or cefuroxime (fluoroquinolone + clindamycin if documented beta-lactam allergy)

Oklahoma Foundation for Medical Quality Appropriate Antibiotics Appropriate Antibiotics National Surgical Infection Prevention Project n Colorectal surgery Oral (after effective mechanical bowel prep) administered for 18 hours preop –neomycin sulfate + erythromycin base, or –neomycin sulfate + metronidazole Parenteral –cefoxitin, cefotetan, cefmetazole, or cefazolin + metronidazole –(fluoroquinolone + clindamycin if documented beta-lactam allergy)

Oklahoma Foundation for Medical Quality Impact of Prolonged Antibiotic Prophylaxis n 2,641 CABG patients Grp 1 - < 48 hours of antibiotics Grp 2 - > 48 hours of antibiotics n SSI Rates Grp % (131/1502) Grp % (100/1139) n Antibiotic resistant pathogen - Grp 2 Odds Ratio 1.6 (95% CI: ) Harbarth S, et al. Circulation

Oklahoma Foundation for Medical Quality Antibiotic Prophylaxis Antibiotic Prophylaxis Duration n In summary - Most studies have confirmed efficacy of  12 hrs of prophylactic antibiotics Many studies have shown efficacy of a single dose Whenever compared, the shorter course has been as effective as the longer course and results in less antibiotic resistance

Oklahoma Foundation for Medical Quality Surgical Infection Prevention n Besides appropriate antibiotic selection, what else reduces infection?

Oklahoma Foundation for Medical Quality HICPAC - SSI Prevention Guidelines Category 1 No prior infections15 air changes/hr in O.R. Do not shave in advance 1 Keep O.R. doors closed Control glucose in D.M. ptsUse sterile instruments Stop tobacco useWear a mask* Shower with antiseptic soapCover hair* Prep skin with approp. agentWear sterile gloves* Surgeon’s nails shortGentle tissue handling Surgeons scrub handsDPC for heavily contaminated Exclude infected surgeonswounds Give prophylactic antibioticsClosed suction drains (when used) Pos pressure ventilation in O.R.Sterile dressing x hr SSI surveillance with feedback to surgeons 1 Every published study of razor shaving has shown increased infection rates!

Oklahoma Foundation for Medical Quality Enhanced Perioperative Glucose Control in Diabetics n 2,467 diabetic patients undergoing cardiac surgery Control group - subcutaneous insulin Treatment group - IV insulin infusion n Results Controls - 2.0% SSI rate (19/968) Treatment- 0.8% SSI rate (12/1499), P=0.01 Furnary AP, et al. Ann Thorac Surg

Oklahoma Foundation for Medical Quality Perioperative Glucose Control n 1,000 cardiothoracic surgery patients n Diabetics and non-diabetics with hyperglycemia Patients with a blood sugar > 300 mg/dL during or within 48 hours of surgery had more than 3X the likelihood of a wound infection! Latham R, et al. Infect Control Hosp Epidemiol

Oklahoma Foundation for Medical Quality Temperature Control n 200 colorectal surgery patients control - routine intraoperative thermal care (mean temp 34.7°C) treatment - active warming (mean temp on arrival to recovery 36.6°C) n Results control - 19% SSI (18/96) treatment - 6% SSI (6/104), P=0.009 Kurz A, et al. N Engl J Med Also: Melling AC, et al. Lancet (preop warming)

N Engl J Med

Oklahoma Foundation for Medical Quality Reducing Surgical Infections Reducing Surgical Infections Summary n In addition to usual infection control: Appropriate antibiotic treatment –timing, selection, duration (intra-op dosing for long cases or excess blood loss) Avoid shaving and other HICPAC recommendations Blood glucose control (diabetics and non-diabetics) Temperature control (goal 37°C) Supplemental O 2
