Hyperhidrosis increases the risk of postoperative infections after shoulder arthroplasty and rotator cuff repair

This is the authors' abstract. We don't add key points for this paper.

Background: Hyperhidrosis (HH), or excessive sweating, has been associated with higher rates of infections. Despite being a relatively common condition, its impact on postoperative outcomes following orthopedic procedures in proximity to the axilla, such as rotator cuff repair (RCR) and shoulder arthroplasty (SA), remains unknown. Methods: A retrospective cohort study was conducted using the TriNetX globally federated database. Patients with and without HH who underwent either RCR or SA were matched based on patient demographics and comorbidities. A standard difference of <0.1 was used to assess success of propensity score matching. Primary outcomes were 90-day postoperative superficial soft tissue infections (SSTIs), deep infections, and wound complications. Tests of significance and risk ratios (RR) with 95% confidence intervals were calculated. Results: < .001). There was no significant difference in the rates of deep soft tissue infections between the HH and non-HH groups for both RCR and SA. Discussion: HH is associated with an increased risk for 90-day complications including SSTIs, UTIs, and emergency services usage following both RCR and SA. Additional strategies for optimizing surgical care of these patients should be investigated.
