Serotonergic Antidepressants Linked to Increased Bleeding Post-Shoulder Arthroplasty

Overview

This large propensity-matched study of 54,291 patients undergoing total shoulder arthroplasty (TSA) found that perioperative use of serotonergic antidepressants (SSRIs/SNRIs) is associated with elevated bleeding events within 30 days postoperatively. Patients on these medications had higher rates of post-hemorrhagic anemia, hematoma/hemorrhage, and transfusions compared to matched controls.

Background

Total shoulder arthroplasty is increasingly performed for various shoulder pathologies. SSRIs and SNRIs are commonly prescribed antidepressants known to impair platelet aggregation by reducing serotonin in platelets, potentially increasing bleeding risk. While prior studies have linked these medications to bleeding complications in other surgeries, their impact on TSA outcomes had not been studied. This investigation aimed to clarify the association between serotonergic antidepressant use and postoperative bleeding following TSA.

Data Highlights

Key Findings

• Patients on SSRIs/SNRIs had significantly higher odds of bleeding events within 30 days post-TSA.
• Bleeding events included increased rates of post-hemorrhagic anemia, hematoma/hemorrhage, and blood transfusions.
• Propensity matching controlled for demographics, comorbidities, coagulation parameters, and medication use, minimizing confounding.
• The increased bleeding risk was observed despite similar baseline characteristics between cohorts.
• No prior studies had evaluated this association specifically in TSA patients before this investigation.

Clinical Implications

Clinicians should carefully evaluate the bleeding risk in patients undergoing TSA who are prescribed SSRIs or SNRIs. Consideration of perioperative management strategies, including potential modification of serotonergic antidepressant therapy and enhanced monitoring for bleeding complications, may be warranted. Awareness of this association can inform preoperative risk assessment and postoperative care.

Conclusion

Perioperative use of serotonergic antidepressants is associated with increased bleeding complications following total shoulder arthroplasty. These findings highlight the need for heightened vigilance and tailored management in this patient population.
