Higher 2-Year Cumulative Incidence of Mental Health Disorders Following Irrigation and Debridement in Primary Lumbar Fusion.

Introduction: Spinal fusion is an operation that is employed to treat spinal diseases. Surgical site infection (SSI) after lumbar fusion (LF) is a postoperative complication. SSI is treated with irrigation and debridement (I&D), which requires readmittance following discharge or prolonged hospital stays, which are deleterious to patients' mental health. The long-term relationship between treating SSI with I&D and patients' mental health is still understudied. Methods: Using the Mariner dataset from the PearlDiver Patient Records Database using Current Procedural Terminology and International Classification of Diseases procedure codes, retrospective cohort analysis was carried out. This study involved 445,480 patients who underwent LF with at least 2-year follow-up and were followed up for 2 years. Of the patients, 2,762 underwent I&D. Using univariate analysis employing Pearson Chi-square and Student Results: For patients who received I&D, 2-year CI depression (HR: 1.72; 95% CI: 1.49-1.99; Conclusions: In conclusion, 16.8% of patients developed new-onset depression 2 years following I&D, in comparison to 10.3% of those who underwent LF. Patients who underwent I&D following LF were significantly more likely to experience depression and stress. To mitigate negative mental health outcomes, mental health services should be available to patients who underwent surgery.
