Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study aims to investigate the use of BPO and BPO/C as a topical skin preparation and to determine the effects it has in reducing positive superficial and deep cultures in patients undergoing TSA.

3 Groups.
1. Benzoyl Peroxide 5% Gel
2. Phisohex wash (1% triclosan, sodium benzoate 5mg/ml, benzyl alcohol 5mg/ml)
3. Benzoyl Peroxide 5% Gel with Clindamycin Gel 1%

All these are topical skin applications.
Patients are to apply morning and night starting two days prior to surgery and applying their last application the morning of surgery. (Total of 5 applications) The Gel/wash is to be applied liberally to the entire shoulder area as instructed by study investigators and explained with pictures in the patient information consent form document.

Outcomes
Primary outcome [1] 303540 0
This is a composite primary outcome. To quantify the effects of benzyl peroxide and benzyl peroxide with clindamycin skin prep preoperatively on the ability to reduce superficial colonization and deep tissue inoculation of Propionibacterium. acnes (P. acnes).
Timepoint [1] 303540 0
Pre-op and intraoperatively swabs will be taken to determine positive P. acnes culture rate.
Secondary outcome [1] 339242 0
To determine the rate of P. Acnes contamination in primary total shoulder arthroplasty.
Timepoint [1] 339242 0
Following growth of cultures taken intra-operatively - assessed by swabs of shoulder skin area and deep swabs
Secondary outcome [2] 340178 0
To determine the level of compliance relating to application of 3 different shoulder preparations prior to arthroplasty.
Timepoint [2] 340178 0
Compliance with the various skin preparations will be completed at the 2 week follow-up via survey.
Secondary outcome [3] 341006 0
To determine the rate of P. Acnes innoculation in primary total shoulder arthroplasty.
Timepoint [3] 341006 0
Following growth of cultures taken intra-operatively - assessed by swabs of shoulder skin area and deep swabs

Eligibility
Key inclusion criteria
Inclusion criteria:
1. Male or Female
2. Age 30-90
a. This age range depicts the typical population that undergo total shoulder arthroplasty. Participants less than 30 years are not amenable to a total shoulder arthroplasty. Patients older than 90 years often have much higher co-morbidity and have an increased risk of complications and thus do not typically have total shoulder arthroplasty.
4. Patients who require a primary TSA for treatment of OA or rotator cuff injuries
Minimum age
30 Years
Maximum age
90 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Exclusion criteria include:
Patients with active infection
Patients with BMI >40, (may impact on study)
Patients who are pregnant or planning on becoming pregnant during the course of the study
Patients unable to provide informed consent
Patients who have undergone previous arthroplasty, have had previous infection, previous surgical procedures or injection into the shoulder within the previous 6 months prior to surgery.
Patients with documented allergy to any of the skin preparation solutions
Patients with English as second language unless understanding English proficiently or a translator service is available
