Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The current study seeks to assess if the XPERIENCE® Advanced Surgical Irrigation (XASI) wash can reduce the incidence of Cutibacterium acnes (C. Acnes) pathogen contamination in shoulder arthroplasty surgery. XASI is an intra-operative surgical irrigant employed to cleanse and remove debris including micro-organisms, from the surgical wound space. It was designed as a no-rinse intraoperative surgical irrigation solution. It consists of citric acid, sodium citrate, and sodium lauryl sulfate in water. Citric acid and sodium citrate serve as pH buffers and aid in metal ion chelation, while sodium lauryl sulfate acts as a surfactant, assisting in debris removal including micro-organisms.

XASI will be placed into the wound (following skin incision and once the wound is opened to expose the shoulder joint) as a wash and allowed to remain in the surgical field until the shoulder arthroplasty procedure has been completed. Following the completion of the surgical procedure, the wound will then be washed appropriately with normal saline irrigation prior to wound closure. For each procedure, a 500ml container is emptied into the surgical wound site in all cases.

Recruited patients will be randomized into two groups: 1) specimen swabs taken before receiving 500ml of XASI (Group 1, which is the control group for the purpose of the study), or 2) receiving 500ml of XASI before specimen swabs are taken (Group 2, which is the intervention group for the purpose of the study). All participants will therefore undergo the XPERIENCE® wash. Swabs will be taken from six different sites from around the skin incision and surgeon’s instruments, and is expected to add an extra 2-3 minutes to the operating time.

Treatment: Drugs
Comparator / control treatment
While there is no comparator as such, Group 1 has been allocated as the control group for the purpose of the study (specimen swabs taken before receiving 500ml of the XPERIENCE® wash). All participants will undergo the XPERIENCE® wash. However, swabs will be taken from patients randomized to two groups which will be either before (Group 1, which is the control group for the purpose of the study) or after (Group 2, which is the intervention group for the purpose of the study) having the XPERIENCE® wash applied.

Outcomes
Primary outcome [1] 340986 0
Presence of Cutibacterium Acnes contamination. Six swab sites will be assessed, with a composite score reviewed from these six sites. If three (or more) of the six swabs test positive for C. acnes, a positive infection will be recorded for this primary outcome. Swabs will be taken from the following six sites: one at the edges of the skin incision (at the exposed subdermal layer of the incision), four from the surgeon’s instruments (outside scalpel blade, inside scalpel blade, forceps and the tip of the surgeon’s glove), and one at the edges of the skin incision.
Timepoint [1] 340986 0
Samples will be assessed for contamination at 24 and 48 hours post-intervention application for aerobic plates and at 48 hours, 5, 10, and 14 days post-intervention application for anaerobic plates. The primary timepoint is 14 days post-intervention application.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomization will be undertaken via concealed envelopes provided at the time of surgery (Group 1 = microscopy, culture and sensitivity (MC&S) swabs taken before receiving 500ml of XASI, Group 2 = receiving 500ml of XASI before microscopy, culture and sensitivity swabs are taken).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization will be undertaken via a random number generator.

Efficacy
Statistical methods / analysis
Statistical analysis will be performed using SPSS software (SPSS, Version 29.0, SPSS Inc., USA), with statistical significance determined at p<0.05. Statistical analysis will investigate differences in the proportion of patients with C. acnes incidence, across each of the swab sites, using chi-square tests (proportions).
