According to a study published online in the Journal of Shoulder and Elbow Surgery, a culture of unprepared skin taken preoperatively may help predict Propionibacterium load among revision shoulder arthroplasty patients. 

The authors conducted a prospective study of 60 patients without clinical evidence of infection. They took a preoperative culture of each patient’s skin surface prior to skin preparation, along with multiple deep tissue and explant cultures at the time of surgery. Based on multivariate analysis, the authors found that preoperative specimen Propionibacterium value was predictive of Propionibacterium load in the revised shoulders as indicated by total and averaged shoulder Propionibacterium score.
