Improving Case Selection for Perioperative S. Aureus Transmission Surveillance to Reduce Surgical Site Infections

July 6, 2021 updated by: Randy Loftus
The first patient in the dyad will receive the bundle, which includes patient decolonization methods, environmental cleaning in the OR, a hand hygiene system located on the IV pole for the anesthesia provider, and intravascular catheter and syringe tip disinfection practices. The second patient in the dyad will receive usual care. Both patients will be surveyed by obtaining swab samples at the beginning and end of the surgery using the OR PathTrac kits. The OR PathTrac software (RDB Bioinformatics, Omaha, NE 68154) uses algorithms to guide analysis of the S. aureus isolates and to identify transmission events. Transmission stories are processed by the software to generate transmission maps that identify improvement successes and failures. It also identifies actionable steps to improve the bundle. The perioperative infection control team then uses this information to continually optimize the bundle, and the software to measure the effect.

Detailed Description

Surgical site infections increase patient morbidity and healthcare costs. The Centers for Disease Control and Prevention emphasizes improved basic preventive measures to reduce bacterial transmission and infections for patients undergoing surgery.

Patients undergoing planned oncologic gynecological and plastic surgery will be entered as dyads into a worksheet each day that will rank and select the optimal cases. The research assistants consent both patients in the dyad to the study while they are in the Day of Surgery Admissions area. The first patient in the dyad will receive the bundle, which includes patient decolonization methods, environmental cleaning in the OR, a hand hygiene system located on the IV pole for the anesthesia provider, and intravascular catheter and syringe tip disinfection practices. The second patient in the dyad will receive usual care. Both patients will be surveyed by obtaining swab samples at the beginning and end of the surgery using the OR PathTrac kits. The OR PathTrac kits are obtained from and analyzed for S. aureus isolates by RDB Bioinformatics. The OR PathTrac software (RDB Bioinformatics, Omaha, NE 68154) uses algorithms to guide analysis of the S. aureus isolates and to identify transmission events. Transmission stories are processed by the software to generate transmission maps that identify improvement successes and failures. It also identifies actionable steps to improve the bundle. The perioperative infection control team then uses this information to continually optimize the bundle, and the software to measure the effect.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
First patient in the case pair
This patient will receive the treatment bundle. S. aureus transmission surveillance will be conducted.
Patient decolonization within one hour of incision, improved environmental cleaning (frequency and quality, including but not limited to targeted use of no touch disinfection with UV-C treatment), provider hand hygiene leveraging proximity, improved catheter disinfection, and surveillance optimization.
Second patient in the case pair
This patient will receive usual care. S. aureus transmission surveillance will be conducted.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time course in S. aureus transmission decline with the intervention.
Time Frame: Up to 52 weeks
S. aureus transmission events by time.
Up to 52 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Systematic selection of sequential cases in operating rooms for surveillance to reduce sample size and increase power.
Time Frame: Up to 52 weeks
The outcome is the proportional reduction in the necessary sample size of pairs of cases achieved by systematic selection of sample cases as compared with random selection.
Up to 52 weeks
