NCT03402945

Brief Summary

This vanguard study will be conducted at two study sites in Canada. It is a cluster randomized trial to test a combination of two antibiotics for antibiotic prophylaxis as compared to routine prophylaxis with one single antibiotic, and to test a negative-pressure wound management system (Prevena) versus standard wound dressing to reduce chest wound infections.

Outcome Measures

Primary Outcomes (3)

  • Adherence to the wound management system

    goal is \>90%

    Prevena or standard wound dressing applied after surgery as per protocol, assessed up to 90 days after surgery

  • Adherence to the antibiotic regimen

    goal is \>90%

    Cefazolin: within an hour of surgery; one intra-operative dose at 4 hours after the first dose or upon wound closure (whatever comes first); two post-operative doses q8h. Vancomycin: initially intravenously; second dose 12 hrs after the first dose.

  • Loss of follow-up

    goal is \<10%

    up to 90 days after surgery

Secondary Outcomes (7)

  • Deep incisional and organ/space sternal-surgical site infection (s-SSI)

    up to 90 days after surgery

  • Wound dehiscence

    up to 90 days after surgery

  • C. difficile infection

    up to 90 days after surgery

  • Mortality in patients with an active infection

    up to 90 days after surgery

  • ICU (Intensive Care Unit) and hospital stay

    Length of ICU - from date of surgery to initial ICU discharge date, assessed up to 90 days after surgery. Hospital Stay - date of surgery to date of hospital discharge, assessed up to 90 days after surgery.

  • +2 more secondary outcomes

Study Arms (4)

Arm 1

ACTIVE COMPARATOR

cefazolin prophylaxis plus Prevena negative-pressure wound management system . Cefazolin 2g (or 3g if greater than 120kg body weight) will be given within an hour of surgery, followed by one intra-operative dose of cefazolin at 4 hours after the first dose or upon wound closure (whatever comes first), and finally two post-operative doses q8h. Prevena will be applied to all diabetic and/or obese patients (BMI \>30kg/m2) at the end of surgery on the sternal as well as the vein harvest site (if open saphenous vein harvest) in the OR and left in place for 7 day

Device: PrevenaDrug: Cefazolin

Arm 2

ACTIVE COMPARATOR

cefazolin and vancomycin prophylaxis plus Prevena negative-pressure wound management system. Cefazolin 2g (or 3g if greater than 120kg body weight) within an hour of surgery, followed by one intra-operative dose of cefazolin at 4 hrs after the first dose or upon wound closure (whatever comes first), and finally two post-operative doses q8h. Vancomycin at roughly 15mg/kg body weight intravenously, i.e. 1g, or 1.5g if greater than 85kg body weight. No intra-operative dose of vancomycin will be given, and a single second dose will be given 12 hours after the first dose. Prevena will be applied to all diabetic and/or obese patients (BMI \>30kg/m2) at the end of surgery on the sternal as well as the vein harvest site (if open saphenous vein harvest) in the OR and left in place for 7 days.

Device: PrevenaDrug: CefazolinDrug: Vancomycin

Arm 3

ACTIVE COMPARATOR

cefazolin prophylaxis plus standard wound dressing. Cefazolin 2g (or 3g if greater than 120kg body weight) within an hour of surgery, followed by one intra-operative dose of cefazolin at 4 hours after the first dose or upon wound closure (whatever comes first), and finally two post-operative doses q8h. Standard wound dressing: non-negative wound dressing as standard of care at the study site.

Drug: CefazolinOther: standard wound dressing

Arm 4

ACTIVE COMPARATOR

cefazolin and vancomycin prophylaxis plus standard wound dressing. Cefazolin 2g (or 3g if greater than 120kg body weight) within an hour of surgery, followed by one intra-operative dose of cefazolin at 4 hours after the first dose or upon wound closure (whatever comes first), and finally two post-operative doses q8h. Vancomycin at roughly 15mg/kg body weight intravenously, i.e. 1g, or 1.5g if greater than 85kg body weight. No intra-operative dose of vancomycin will be given, and a single second dose will be given 12 hours after the first dose. Standard wound dressing: non-negative wound dressing as standard of care at the study site.
