Participant Flow

From 2015 to 2017, patients with abdominal trauma or acute surgical abdomen were recruited from participating research sites' universities, hospitals and/or emergency departments.

The planned sample size was 1100 screened, 650 completed \& 600 evaluated. However, the study was terminated early after the interim analysis due, in part, to issues with the accuracy and completeness of the data collected. There were 627 consented and 617 randomized subjects. The intent-to-treat (ITT) population was defined as all randomized subjects. Of these, 309 were randomized to Irrisept and 308 to Standard of Care.

Measure
Irrisept
For subjects randomized to the investigational group, Irrisept was used during the surgical procedure, per the provided instructions for use. Irrisept consists of two containers: (1) a sterile bottle of 450 mL of 0.05% Chlorhexidine Gluconate (CHG) in 99.95% sterile water and (2) a sterile bottle of 450 mL of sterile 0.9% normal saline.
Standard of Care (SoC)
For subjects randomized to the control group, any Standard of Care (SoC) irrigation solution, preferred by the site, was used during the surgical procedure.

PRIMARY outcome

Timeframe: 30 (+/- 3) days post-surgical procedure

Population: Data is from the percentage of subjects that reported an SSI for the mITT subject populations.

The primary endpoint was the rate of SSIs observed 30 days from the date of the index operation.

SECONDARY outcome

Timeframe: 30 (+/- 3) days post-surgical procedure

Population: Data is from the percentage of subjects that reported hospital readmission, due to an SSI, for the mITT subject populations.

A secondary endpoint was the rate of Irrisept versus SoC subjects that required hospital readmission due to SSIs.

SECONDARY outcome

Timeframe: 0 days

Population: No data was collected for either randomization group, towards this objective. Therefore, the success or failure of this endpoint was not assessed.

A secondary endpoint was the estimated hospital cost to charge ratio between Irrisept and SoC subjects. No data was collected towards this objective; thus, the success or failure of this endpoint was not assessed.

SECONDARY outcome

Timeframe: 30 (+/- 3) days post-surgical procedure

Population: Data is from the average number of days in the hospital for the mITT subject populations.
