Structured Abstract: Objective: Closed-suction drains are commonly placed after thoracolumbar surgery to reduce the risk of post-operative hematoma and neurologic deterioration, and may stay in place for a longer period of time if output remains high. Prolonged maintenance of surgical site drains, however, is associated with an increased risk of surgical site infection (SSI). The present study aims to examine the literature regarding extended duration (≥24 h) prophylactic antibiotic use in patients undergoing posterior thoracolumbar surgery with closed-suction drainage. Methods: This systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Relevant studies reporting the use of 24-h post-operative antibiotics compared with extended duration post-operative antibiotics in patients undergoing posterior thoracolumbar surgery with closed-suction drainage were identified from a PubMed database query. Results: Six studies were included for statistical analysis, encompassing 1003 patients that received 24 h of post-operative antibiotics and 984 patients that received ≥24 h of post-operative antibiotics. The SSI rate was 5.16 % for the shorter duration group (24 h) and 4.44 % (p = 0.7865) for the longer duration group (≥24 h). Conclusions: There is no significant difference in rates of SSI in patients receiving 24 h of post-operative antibiotics compared with patients receiving ≥24 h of post-operative antibiotics. Shorter durations of post-operative antibiotics in patients with thoracolumbar drains have similar outcomes compared to patients receiving longer courses of antibiotics. Shorter durations of antibiotics could potentially help lead to lower overall cost and length of stay for these patients.

Background: Indications for deep brain stimulation (DBS) are rapidly growing within functional neurosurgery. The objective of this study was to characterize national trends in demographics and complications across distinct populations of DBS patients. Methods: We identified patients from the 2008–2018 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Participant Use Data File (PUF) who underwent an implantation or revision procedure for DBS. Summary statistics for postoperative infection rate, noninfectious complication rate, total hospital length of stay, discharge disposition, mortality, reoperation or readmission, and time from operation to readmission were obtained. Patients were categorized by diagnosis for DBS treatment. Outcomes for each diagnosis group were compared to outcomes for the total study population. Results: DBS patients who underwent primary implantation procedures had low rates of postoperative infections (1.2%), noninfectious complications (0.8%), and mortality (0.1%) and a high likelihood of discharge home (97.6%). In addition, a large percentage of patients presented for revision or removal of neurostimulators (34.2% of cases) or treatment of long-term hardware infection (4.5%). Compared with patients with other diagnoses, patients with Parkinson disease experienced lower rates of noninfectious complications (odds ratio 0.32; 95% CI, 0.15–0.63; p = 0.002) and fewer unplanned reoperations (odds ratio 0.60; 95% CI, 0.39–0.92; p = 0.02). Conclusion: Analysis of a national database suggests that DBS is a relatively safe treatment across several different patient populations. These overall favorable results support the continued practice of DBS surgery and provide encouraging validation for increasing access to DBS therapy for new indications that are being actively investigated.
